How to reduce the gap of the screw lift_leeson motors

How to reduce the gap of the screw liftHow to reduce the clearance of the screw lift and improve the fit of the screw and nut of the actuarial screw lift are very important. Therefore, it is necessary to pay attention to eliminate the gap between the screw and the nut during the maintenance of the equipment. How to reduce the clearance of the screw lift to improve the actuarial degree? 1. Compensation for axial sway: Firstly, measure the verticality error of the bearing positioning end face on the main shaft and the center line of the main shaft and its direction position: measure the end face circular runout error of the thrust bearing and its highest point position and finally position the bearing. The highest point of the end face is shifted. The amount of error in axial yaw can be reduced. For example, gears, worm gears, etc., should first measure the radial runout value of the part on the outer circle and the axis at the part assembly, and determine the position at the highest point. During assembly, the highest point of the radial runout of the two is moved and adjusted so as to be in a direction different from each other by 180° to cancel the local radial runout error. When assembling the rolling bearing, the highest point of the radial runout of the journal and the lowest point of the radial runout of the inner bore of the rolling bearing can be placed at the same position. 2. Remedy of radial circular runout: For the parts assembled on the shaft, in order to reduce the radial runout value of the front end of the main shaft, the maximum radial runout points generated by the front and rear bearings can be located in the same axial plane. The center line of the main shaft is on the same side, and the error value of the front bearing is made smaller than the error value of the rear bearing. Its load carrying capacity is much higher than that of the staggered helical gear mechanism. The displacement compensation of the screw lifter-shift compensation is often used to compensate for the error of single-item precision. In order to be assembled with the lowest point of the circular end face of the thrust bearing.CAMEL Transmission Machinery Factory is a professional supplier,distributor and manufacturer of gear reducers and related accesories. including rotary reducer,worm gearbox, servo-gearbox, planetary gearboxes,planetary gear reducer, helical gear reducers,planetary gearbox,right angle gear reducer, gear reduction,gear motors, electrical motors,DC motors, DC gear motor,dc gearedmotors,AC gear motor,AC motors, servo motors,servomotor, bearings, spur gear,helical gear,bevel gear,worm gear,planetary gear, couplings, oil seals, belts, chains, etc.If you have any need, please feel free to contact CAMEL:
