What is Shaft Support
Linear shaft supports, also called shaft support blocks, are components that position the shafts on which linear bushings or bearings slide. Typically two shafts are arranged parallel to each other and supported by four shaft supports. If you want to know the specifications and prices of Shaft Support, please contact us!
Improving Load Handling
Shaft supports are designed to handle various loads effectively, whether they are radial, axial, or a combination of both. This capability is essential in applications where shafts are subjected to heavy loads, ensuring that the load is distributed evenly and preventing excessive stress on any single component.
Enhancing Operational Safety
By preventing misalignment and excessive vibrations, shaft supports contribute to the overall safety of the mechanical system. A well-supported shaft reduces the likelihood of mechanical failures that could pose safety hazards to operators and nearby personnel.
Customizability and Versatility
Shaft supports come in various designs and materials, making them adaptable to a wide range of applications. Whether used in industrial machinery, automotive systems, or aerospace technology, the versatility of shaft supports allows them to meet specific operational requirements and environmental conditions.
Facilitating Higher Speeds and Loads
Well-designed shaft supports enable mechanical systems to operate at higher speeds and handle greater loads without compromising stability or safety. This capability is particularly valuable in high-performance applications where maximizing efficiency and output is critical.
Advantages of Shaft Support
Enhancing System Stability
Shaft support is vital for maintaining system stability. Properly supported shafts can stay correctly aligned and positioned during operation, preventing issues like vibration and misalignment that can lead to wear and damage. This stability ensures smoother operation of the entire system and reduces downtime caused by mechanical failures.
Extending Equipment Lifespan
Shaft support significantly extends the lifespan of mechanical equipment. Adequate support alleviates the burden on bearings and other transmission components, reducing the risk of wear and fatigue damage. This not only decreases the frequency of component replacements but also prolongs the overall life of the equipment, lowering the total cost of ownership.
Increasing Precision and Efficiency
Proper shaft support enhances the precision and efficiency of mechanical systems. In fields that require high-precision operations, such as manufacturing and machining, stable and well-supported shafts are crucial for maintaining accuracy. Improved precision translates to higher-quality outputs and increased productivity.
Reducing Maintenance Costs
With shaft support, the wear and tear on mechanical components are minimized, which translates to less frequent maintenance and repairs. This reduction in maintenance needs leads to lower maintenance costs over time, making the operation more cost-effective.
Application of Shaft Support
Machinery
Guide shaft supports are widely used in the machinery industry. They are mainly used to support and fix the rotation center position of various shafts so that they cannot move. For example, in machine tools, guide shaft supports are often used to support and fix the rotation center position of the worktable to ensure the machining accuracy of the machine tool.
Automotive
Guide shaft supports are also widely used in the automotive industry. They are mainly used to support and fix the rotation center position of the engine and transmission system to ensure the smoothness and accuracy of car driving. For example, in automobile engine manufacturing, guide shaft supports are often used to support and fix the rotational center positions of the intake manifold and exhaust manifold.
Shipping
Guide shaft supports are also used in the shipping industry. They are mainly used to support and fix the rotation center position of the hull and rudder stock to ensure the stability and accuracy of ship navigation. For example, in ship construction, guide shaft supports are often used to support and fix the rotation center position of the hull formwork and rudder stock.
Aerospace
Guide shaft supports are widely used in the aerospace industry. They are mainly used to support and fix the rotation center position of engines and transmission systems to ensure the stability and accuracy of the aircraft. For example, in aircraft engine manufacturing, guide shaft supports are often used to support and fix the rotation center position of the engine.
Three Easy Ways to Reduce Maintenance Costs for Linear Systems
Look and Listen
Once the system is installed, tuned, and run-in, pay attention to any changes in running smoothness or noise. Rough running can indicate excess contamination or damage to bearing surfaces, while an increase in running torque often signals extreme wear. Noise has several potential causes, but when dealing with ball or lead screw assemblies, misalignment of the end bearings is one of the most common causes. In linear guide systems, noise can be caused by misalignment of guide rails or uneven loading on bearing blocks. If operational parameters change, the system may require a new tuning routine to adjust the servo system to the new application requirements.
Be Proactive
When it comes to maintenance, the most important component of a linear system are the seals. Seals keep contamination out and lubrication in, and they're relatively easy to visually inspect and replace. For linear actuators, if a cover is used, it's good practice to remove it periodically to inspect for wear and check for any contamination that may have made its way inside the unit. Whether you're dealing with bearing seals or an actuator cover, if the fit is loose or if contact between the seal and the bearing surface is degrading, it's better to perform a simple, low-cost replacement than to wait until major damage occurs.
Use the Right Components
Regardless of the application, there's a good chance that at some point in the machine's service life, a linear bearing or screw component will need to be replaced. To make repair and replacement as painless as possible (and potentially less costly), use parts that can easily be replaced. This means linear rails and bearings that are interchangeable and ball nuts with adjustable preload, where possible. Of course, there are applications that require the benefits of matched-set linear guides or ball nuts with factory-set preload, but advances in manufacturing capabilities have made it possible to get the same or comparable precision and performance from components that are machined separately. And replacing a linear guide carriage or screw nut generally requires much less effort and time than replacing an entire guide rail or ball screw assembly.
How to Choose Shaft Support for Your Application
Load Capacity
Determine the maximum load that the linear guide will need to support. Consider both static and dynamic loads, as well as any additional forces or moments acting on the system. It is also important to consider if the rail guides are used in a horizontal or a vertical application. Typically, the vertical application will require three times more load than a horizontal application. In the image below, you can see a common setup of a palletiser which has both X-axis and Y-axis linear guides. For Y-axis, you have to consider the distance to the load (a) and also the weight of the load itself (F). This will help you choose a linear guide with the appropriate load capacity and ensure stable and reliable operation.
Number of Blocks Per Rail
The number of blocks per rail and the distance between each block per rail depends on the surface area of the steel plate or object mounted on the block(s). Some linear guide blocks consist of 2, 4 or more mounting holes, and some blocks are wider than others. If two blocks are required per rail, it is best to use the widest possible distance between two blocks to operate in the more stable fashion.
Speed and Acceleration: Define the desired travel speed and acceleration for your application. Higher speeds and accelerations may require linear guides with specialized features, such as low friction or enhanced lubrication systems, to minimize heat generation and wear.
Environment and Conditions: Assess the operating environment of your application. Consider factors such as temperature extremes, humidity, dust, or corrosive substances. These conditions may dictate the choice of materials, sealing options, and protective coatings for the linear guide. Shafttech offers many grades of seal for linear guides. The standard linear guide comes with end seal and side seal. We will also be able to reinforce your current linear guides with more seals if needed, including scrappers that keep out dust in large amounts.
Accuracy and Precision
Evaluate the required level of precision and repeatability for your application. Some applications, such as CNC machines or optical systems, demand high accuracy, while others may have more lenient requirements. Consider factors like positioning tolerance, backlash, and smoothness of motion. For Shafttech, we offer varying levels of precision for linear guides, as well as the option of having linear guide parallelism when two sets of linear guides are used in a parallel system with little to no misalignment.
Maintenance and Cost Factors
When selecting a linear guide, it's crucial to consider the maintenance requirements and associated costs. Some factors to consider include:
Lubrication: Determine the lubrication requirements of the linear guide. Some guides require regular lubrication, while others feature self-lubricating properties or maintenance-free options. The ease of lubrication is also important. In cases where the linear guides are highly inaccessible or downtime has to be reduced, we will recommend a auto-lubrication system that acts as a "juice pack" for the linear guide to run for long periods of time. Watch this video to learn more about our auto-lubrication system.
Service Life: Evaluate the expected service life of the linear guide. Consider factors such as load capacity, operating conditions, and manufacturer specifications. Choosing a caged linear guide (BGC) can reduce vibration and prolong longer service life.
Frequently Asked Questions
Q: What is the guide shaft support?
The guide shaft is usually a solid shaft, with both ends supported on the guide shaft support through bearings. The function of the guide shaft support is to fix the shaft in the correct position and provide the support and fixation required when the shaft rotates. The bearing can be connected to the shaft in different ways, for example by bolting, welding or interference fit.
In some applications, guide shaft supports can also provide additional functions, such as controlling the rotation direction of the shaft, limiting the rotation angle of the shaft, increasing the rigidity of the shaft, etc. The design and manufacture of guide shaft supports need to take into account a variety of factors, including load, speed, accuracy, temperature, etc., to ensure that the shaft remains stable, precise and reliable during use.
Q: What Materials are the Guide Shaft Supports Made of?
45# steel is a high-quality carbon structural steel with high strength and hardness, but it requires surface treatment to achieve anti-rust effect.
SUS304 stainless steel is a food-grade stainless steel with good corrosion resistance and wear resistance, and can maintain surface gloss for a long time, but the cost is relatively high.
Aluminum alloy is a lightweight material with low density and high strength. It has the characteristics of low cost, easy processing and corrosion resistance, but it has poor rigidity. The commonly used material in guide shaft supports is aluminum alloy because it can meet the requirements of high speed and high precision and can effectively reduce costs.
In addition to the above three common materials, there are other materials to choose from, such as Monel alloy, high-strength and high-hardness alloy, etc. Each material has its own characteristics and scope of application, and needs to be selected according to specific applications and requirements.
When selecting a guide shaft support, you need to consider the use environment, working accuracy and requirements, cost and other factors of the mechanical equipment, and select the appropriate material and model to meet the use requirements and working requirements of the mechanical equipment. At the same time, correct installation and use are also one of the key factors to ensure long-term stable operation of the guide shaft support.
Q: How Much Torque Can the Guide Shaft Support Bear?
In the machinery industry, guide shaft supports are usually used to support and fix the rotation center position of various shafts so that they cannot move. According to different data and application scenarios, the maximum torque that the guide shaft support can withstand varies. Generally speaking, the bearing capacity of the guide shaft support can reach between 10KN·m and 30KN·m.
