Repair steps of worm gear reducer

时间:2018-11-03 16:46   tags: Technology Frontier  

The repair procedure of the worm gear reducer is a mechanism that uses a gear speed converter to reduce the number of revolutions of the motor to the required number of revolutions and obtain a larger torque.Among the mechanisms currently used to transmit power and motion, the application range of the repair procedures of Tianjin worm gear reducer is quite wide.It can be seen in almost all kinds of mechanical transmission systems, from ships, automobiles, locomotives, heavy machinery used in construction, processing machinery and automated production equipment used in the machinery industry, to the common ones in daily life Home appliances and so on.
However, in daily production and life, Tianjin worm gear reducer repair procedures will inevitably have such failures, so how should it be repaired?What is the maintenance process?
Let's start with the inspection first:
1. Inspection of bearings.Clean with heated mineral oil until the inner seat ring is gently rotated by hand and there is no jamming in any direction.The cleaned bearing shall be checked for clearance with a feeler gauge.
2. Inspection of gears.The gear must not have broken teeth, and there must be no cracks or peeling on the tooth surface.
3、轴的检查。轴径上的椭圆度和锥度不得大于0.015~0.025mm。轴所有配合尺寸表面粗糙度满足图纸技术要求,超差0.02mm可复用,0.02mm以上需修复后方可使用。轴宽度尺寸对不超0.04mm可复用,对超过0.04mm应更换。
4. Inspection of reducer case and bearing cover.
Then there is disassembly:
1. Clean the slime on the reducer, hoist it to the waste oil point, unscrew the oil drain plug, and drain the waste oil.  
2. Unscrew the connecting plate, bearing cover, reducer interface bolts and tile cover bolts. 
3. Knock off the tapered fixing pin and use a crane to remove the reducer box cover.
4. Remove the high-speed shaft and the driven shaft. 
After finding the reason, it is to "prescribe the right medicine". After this series is completed, it is assembly and acceptance!
Assembly:
1. Install the passive shaft, three shafts, two shafts, and high speed shafts in order.
2. Adjust the gear backlash and axial clearance.
3. The joint surface of the reduction box is evenly coated with sealing glue; close the other box; fasten the tapered fixing pin; fasten the bearing cover and the interface bolt of the box; the driving shaft is flexible and there is no friction.
