The dynamic balancing machine will inevitably cause friction during the application process, and the friction will cause changes in the size, shape and surface quality of the related parts, causing damage and increasing the matching clearance between the related parts. When the gap is beyond the effective range, the accuracy of the relative operation between the components of the balancing machine can be ensured only according to the adjustment gap.
So should we judge and adjust these gaps like this?
1. Adjustment of guide guide precision
For ordinary mechanical equipment, the gap between the sliding guide rails is not suitable. Generally, a 0.03mm or 0.04mm thick feeler gauge is inserted into the end surface position for inspection, and the insertion depth should be less than 20mm. If there is a problem with the rail clearance, be sure to adjust it immediately.
2. Clearance adjustment between the lead screw and the nut of the worm gear screw lift
The screw nut drive of the screw lift is a common mechanism for linear motion. The cooperation of the lead screw and the nut makes it difficult to ensure that there is no gap. Especially after applying one stage, because of the damage, it will increase the gap and endanger the normal use of the machine. For this reason, it is very important to pay attention to eliminating the gap between the screw and the nut during the maintenance of the equipment.
3. Adjustment of the precision of the spindle of the dynamic balancing machine
The precision of the rotation of the main shaft of the dynamic balancing machine is generally determined by the bearing in the premise that the machining deviation of the spindle itself conforms to the standard. The key to adjusting the precision of the spindle rotation is to adjust the clearance of the bearing. Maintaining an effective bearing clearance is critical to the performance of the spindle components and bearing life. For rolling bearings, working with large clearances not only causes the load to concentrate on which rolling element in the direction of the force, but also causes severe stress concentrations in the bearing contact between the inner and outer rings. The condition, reducing the service life of the bearing, also causes the drift of the spindle center line, which easily causes the vibration of the spindle member. For this reason, the adjustment of the rolling bearing must be preloaded, causing a certain amount of interference inside the bearing, causing a certain amount of elastic deformation at the contact between the rolling element and the inner and outer ring raceways to improve the rigidity of the bearing.
For the gap caused by the dynamic balancing machine during use, it is recommended that you must treat it correctly and need immediate adjustment. In order not to endanger the normal use of the machine, daily maintenance work is essential. I hope everyone will pay attention to the quality when purchasing. In addition to good products, it is necessary to strengthen the post-maintenance work for the dynamic balancing machine.
