、蜗轮蜗杆减速机的拆卸 1.Removal of worm gear reducer
First, remove the belt cover, V-belt, pulley, remove the couplings, bolts, lift and remove the bolts at both ends of the worm and the bolts on the split surface of the reducer, and lift the upper cover of the casing on the rubber plate to prevent the middle section Face damage, clean the upper cover, and check for oil leakage at the fastening bolts.
Secondly, remove the lubrication system, remove the worm gear lock nut, remove the worm gear with a special tool, and check the worm gear and worm meshing, including the contact area, position, wear, etc.
Once again, remove the oil seal, clean the case, and check the mid-section for processing.
、检查轴 2.Check the shaft
Journal wear can be repaired by spraying, brushing, and post-electroplating grinding.
120 °相位处重新加工键槽。 The keyway on the shaft is damaged. The keyway can be reprocessed at a phase 120 ° away from the original keyway.

Worm gears with severe abrasion, pitting and gluing (adhesion and tear) can be replaced or repaired with modified worm gears, and worms can be re-formulated.
Worm gears, worm tooth surfaces are lightly glued, pitting and individual tooth surfaces are defective, and can be repaired by milling, scraping and grinding after welding.

Assembly of worm reducer
; 第二步：把涡轮放进下箱体 ; The first step: fix the bearings at both ends of the turbine and install the oil seal ; the second step: put the turbine into the lower case ;
; The third step: cover the box, remember to apply sealant or add a gasket between the box interfaces. Forgot to return oil in this step, fix the box nut, and check whether the turbine is offset or offset when pressing the box. Be sure to adjust ;
; Step 4: Do not crush the end cover of the turbine, or do not install it first ;
- 定不要蛮力装，否则会划伤蜗杆，装蜗杆的轴承和油封 ; Step 5: Put the worm into the worm hole - do not install it with force, otherwise it will scratch the worm, install the worm's bearing and oil seal ;
Step 6: Tighten the end caps of the turbine. The end caps must also be sealed. Then compress the end caps of the worms. Remember to seal them. Turn the worms by hand to see if they can turn and if they are too tight. Degree, until the worm is very easy to handle: Step 7: Check the seal of the reducer, and check the reduction of the reducer.
Cooling method of worm gear reducer
What are the cooling methods of worm gear reducer? The friends you want to know follow us to find out:
1. A cooling coil is installed in the tank oil tank, and the cooling water in the tube takes away some of the heat of the lubricating oil.
Second, the fan is cooled. Install a fan on the worm shaft to increase the heat dissipation to reduce the temperature.
Third, install the lubricant oil external circulation device to reduce the oil temperature.
4. Install cooling fins outside the box to increase the heat dissipation surface.
The operating temperature of the worm gear reducer should be controlled between minus forty degrees Celsius and minus forty degrees Celsius. When the ambient temperature is lower than zero degrees Celsius, it should be heated before starting to fully dissolve the lubricant or use low freezing point lubricant.
