Pay Attention To The Ball Screw Elevator
Because of the difference of the screw, the ball screw will also be different, so the focus will be different. In which situations are ball screw elevators generally applicable, and the focus points that need to be paid attention to in different situations are different, please introduce the precautions:
1. When the ball screw lift is running, it cannot be forced to stop artificially, and the lift will be irreparably damaged.
2. When the elevator works in a dusty environment, it is necessary to use a dust cover telescopic sleeve to protect the lead screw. When using the elevator in the open air, please consider using a cover and other devices to ensure that the ball screw elevator is not protected from wind and rain. direct erosion.
Third, when the ball screw elevator is loaded, the input shaft driving mode cannot be changed to manual operation, which may cause the input shaft to rotate rapidly and cause harm to people.
In different temperature sections, different types of lubricants should be used. Low-temperature lubricants should be used below zero, and high-temperature special greases should be used at high temperatures. Different temperatures will cause the screw lift to be affected by changes in the viscosity of the lubricating oil during operation. , so that the efficiency of the whole machine is reduced, so there must be a sufficient driving source.
6. When the ball screw hoist is running, the temperature of the box should not be too high, generally 0-50 ℃ is better. Make sure that the surface temperature of the movable nut is also within the oscillation range. Ball screw lifts are suitable for high-speed and high-frequency work, so they can be adapted to different environments.
The biggest advantage of ball screw hoist is high speed and high precision. This advantage is determined by an important part of the ball screw elevator. Precision ball pair and high precision worm gear pair. Ball bar lift is especially suitable for high-speed, high-frequency, high-tech equipment.
Rolling friction is to reduce the rolling resistance between the ball and the screw through the lubricant, and increase the sliding amount. Before adding grease, the surface of the ball screw should be thoroughly cleaned to remove dust and particles to avoid wear on the ball screw caused by these contaminants. Compared with the ordinary trapezoidal screw elevator, the ball screw elevator has longer service life and higher quality, and the working life is more than 3 times higher than that of the ordinary trapezoidal screw.
It is proposed to add a dust cover on the lead screw of the ball screw elevator, which can prevent most of the debris and dust from entering the lead screw nut and greatly reduce the wear caused by debris.
