Ball screw lifters are a fundamental lifting component, widely used across various industries. Here's an explanation of the working principle of ball screw lifters:

The ball screw lifting jack is composed of a worm gear reducer and a lead screw, with the reduction section driven by worm gears to power the worm wheel reducer. The worm wheel acts as a lifting nut, coordinating with the lifting screw.

The worm gear features an internal threaded structure, serving as a nut for the lifting screw and working in conjunction with it.

The rise and fall speed of the ball screw lifting mechanism is equal to the input speed of the worm gear divided by the reduction ratio of the worm and worm gear, then multiplied by the pitch of the lifting and falling screw.

Due to its structure, spiral elevators typically use grease for lubrication, with some series utilizing oil lubrication, offering the advantage of stable operation.

The lifting speed of the screw jack is equal to the worm input speed divided by the reduction ratio of the worm and worm gear, then multiplied by the pitch.

Due to the different coefficients of thermal expansion, the temperature rise of the worm gear screw lifting machine will lead to variations in different parts of the worm gear reducer, creating gaps in the mating surfaces.

Grease and other oil-lubricated gearboxes can also experience leaks or lubrication failure under the influence of high temperatures, thinning, or degradation.

Ball screw lifters and worm gear screw lifters, designed with the aim of improving operational efficiency, utilize non-ferrous metals as the primary material. The worm is made of hard steel, and the operation, especially under sliding friction, generates more heat, increasing the temperature of the reducer.

Gearbox worm bearing damage primarily manifests as rust and corrosion. The main cause of this issue is insufficient lubrication of the gear reducer, or lubrication failure due to emulsification of the gear oil.

After the ball screw lifting machine stops operating, the gear oil will emulsify due to condensation water produced by cooling. The screw lifting machine has two speeds: fast P and slow M, which depend on the worm gear ratio.
