To avoid double worm gear and worm reduction motor failure, the first point to speak, it is to a large extent, that is, to pay attention must be to ensure the quality of assembly. In order to avoid the assembly quality of the double worm gear motor, the factory purchased and made some special tools for its own use. When removing and installing worm gear, worm, bearing, gear and other components of the reducer, try to avoid directly using other tools such as hammer Strike.
In the replacement of double worm gear and worm reduction motor gear or worm gear, should try to use the original parts and pairs of replacement; assembly of the output shaft, it is to a large extent that is to pay attention to tolerances , With D≤50mm, H7 / k6, D> 50mm, H7 / m6. At the same time, it is necessary to pay attention to the use of anti-blocking agent or Hongdan oil to protect the hollow shaft and prevent wear and rust, At the same time, it is to a large extent that is to prevent the fouling with the surface, repair time difficult to disassemble phenomenon.
To avoid double worm gear and worm reduction motor failure, to avoid the selection of lubricants and additives. Under normal circumstances, the worm gear reducer will be used 220 # gear oil, for some heavier load, it will start more frequently, the use of relatively poor environment reducer, the plant will use a number of lubricant additives (Such as Anzhi Chemical Company can be good).
When the twin-worm gear motor on the reducer in the stop running time, the gear oil will still be attached to the gear surface, speaking in terms of this, to a large extent, it will form a protective film to prevent heavy Load, low speed, high torque and metal-to-metal contact at start-up.
Finally, on the dual worm gear motor in use, among the additives to a large extent, that is, it will contain a ring regulator and anti-leakage agent, so that is to make double worm gear motor equipment The sealing ring on the soft and flexible, can effectively reduce the lubricating oil leakage phenomenon.
