How to adjust the gap of dynamic balancing machine parts
The dynamic balancing machine must cause friction during use, and friction will cause changes in the size, shape and surface quality of related parts, causing wear and widening the matching clearance between related parts. When the gap is beyond the reasonable range, it will cause the failure or accuracy of the dynamic balancing machine. Zhuo Xuanjin technical engineer feels that the accuracy of the relative operation between the components of the balancing machine can be ensured only by adjusting the clearance. So how should we judge and adjust these gaps?
1. Adjustment of guide rail 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 at the end position for inspection, and the insertion depth should be less than 20mm. If the rail clearance is not suitable, be sure to adjust it in time.
2. Clearance adjustment between the lead screw and the nut of the worm gear screw lift
The screw and nut drive of the screw lift is the most common mechanism for linear operation. The combination of the lead screw and the nut makes it difficult to achieve no gap. Especially after using one stage, because of wear, it will increase the gap and affect the normal operation of the equipment. Therefore, it is necessary to pay special attention to eliminating the gap between the screw and the nut during the maintenance of the equipment.
3. Adjustment of the rotary precision of the dynamic balance machine spindle
The rotation accuracy of the main shaft of the dynamic balancing machine is determined by the bearing in the normal case on the premise that the machining deviation of the spindle itself conforms to the standard. The adjustment of the spindle rotation accuracy is important to adjust the clearance of the bearing. Maintaining a reasonable amount of bearing clearance is important for the performance of the spindle components and the service life of the bearings. For rolling bearings, working with large clearances not only causes the load to concentrate on the rolling element in the direction of the force, but also causes severe stress concentration at the contact between the inner and outer races of the bearing. To reduce the service life of the bearing, it will also cause the drift of the spindle center line, which will easily cause the vibration of the spindle components. Therefore, 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 operation of the dynamic balancing machine, Zhuo Xuanjin technical engineer suggested that you must correctly treat and adjust in time. In order not to affect the normal operation of the equipment, daily maintenance work is indispensable. When paying special attention to selecting high-quality products, it is necessary to strengthen the post-maintenance work for the dynamic balancing machine.
