How to adjust the precision of the planetary reducer?

Regardless of the lubrication effect of the planetary reducer, friction will still occur when the planetary reducer starts.This friction causes changes in the size, shape and surface quality of the parts involved, which leads to wear and increases the fit clearance between the parts involved.Therefore, when the gap exceeds the reasonable range, the accuracy needs to be adjusted.How to adjust the precision of the planetary reducer?The following is the introduction of Tuoda official website editor.

1. Adjust the guiding precision of the guide rail

In general mechanical equipment, whether the gap between guide rails is appropriate or not is usually to insert a 0.03 mm or 0.04 mm thick feeler gauge on the end face, and the insertion depth cannot exceed 20 mm.If the guide rail clearance is improper, it should be adjusted in time.

2. Adjustment of the gap between the screw and the nut of the worm gear screw lift

Screw hoist nut drive is a commonly used screw drive mechanism.The combination of screw rod and nut is difficult to achieve no gap.Especially after a period of use, due to wear and tear, the gap will increase and affect the normal operation of the equipment.Therefore, in the process of equipment maintenance, attention should be paid to eliminating the gap between the guide rod and the nut.

3. Adjustment of the rotation accuracy of the main shaft of the planetary reducer

If the machining error of the main shaft itself meets the requirements, the rotation accuracy of the main shaft of the reducer is generally determined by the bearing.The key to adjusting the rotation accuracy of the spindle is to adjust the bearing clearance.Maintaining a proper bearing clearance is critical to spindle component performance and bearing life.For rolling bearings, when there is a large gap, not only the load will be concentrated on the rolling elements in the direction of force, but also serious stress concentration will occur at the contact between the inner and outer ring raceways of the bearing, shortening the life of the bearing, and The center line of the spindle will drift, which will easily cause the vibration of the spindle components.Therefore, the adjustment of the rolling bearing must be preloaded, so that a certain amount of interference is generated inside the bearing, so that a certain elastic deformation is generated at the contact between the rolling body and the inner and outer ring raceways, thereby improving the stiffness of the bearing.
