Description

The heavy duty belt driven linear actuator EGHP120F has a unique, optimized move area for maximum rigidity and resilience. As a dynamic linear actuator, it attains excessive speeds even with large loads and lengthy strokes.

Product Details

The challenge for mechanical automation systems in the past has been the successful conversion of rotational motion from electric powered or mechanical motors into useful forms of linear motion. A leap forward in this regard, the conveyor belt system represented one of the first useful implementations of rotary to linear motion conversion for use in a manufacturing environment. These systems are able to transport a wide variety of raw materials and workpieces in a far more efficient manner than could previously be accomplished by the use of brute mechanical forces and are extremely useful in production environments.

Today, significant engineering work in the area of rotary motion conversion has yielded a diverse class of linear mechanical actuators which are useful for a broad range of advanced automation applications. The challenge is selecting an appropriate actuator for the desired functionality, be it simply the movement of raw material in a manufacturing environment or the construction of more advanced motion structures designed to move tooling into precise positions.

Product Description

In order to select the proper linear mechanical actuator, some important considerations, such as the desired load capacity, or thrust force, and crucial stroke distance, need to be taken into account. While these are primary considerations, others such as maintenance burden certainly play an important role as well.

Two widely used types of mechanized linear actuators are differentiated by their drive mechanisms- belt-driven and ball screw driven actuators. Both sorts are employed in similar types of applications, however the two differ significantly in function. Each type possesses unique strengths and important limitations which have to be carefully considered in the selection of an actuator.

Belt-Driven Actuators: The belt-driven actuator operates below the same principles as the conveyor belt system. The belt drive translates rotary motion to linear motion via a timing belt connected between two circular pulleys. The timing belt is normally made from a fiber-reinforced elastomer, but many other belt materials are available for more demanding applications. The belt contains teeth that interface with the rotor pulleys to efficiently transfer torque and prevent slipping. The belt drive is enclosed within an aluminum body while the carriage rides on top, and the driveshaft interface is typically situated perpendicular to the facet of the actuator.
