Share the use and maintenance of worm gear reducer

The worm gear reducer should check the lubricating oil before use, s helical gear worm gear reducer, lubrication requirements:
1. The lubrication method is generally oil immersion lubrication. When the sliding speed of the worm throat is greater than 10m / s, oil injection lubrication should be used.
2. When the ambient temperature is 0-40 ℃, the lubricating oil grades used at different working speeds must comply with the provisions in the "Lubricating Oil Selection Table".
3. The temperature rise of the reducer during working does not exceed 80 ℃, and the temperature of the lubricating oil must not exceed 100 ℃.
After checking the lubricant, the reducer should be tested before use, and the corresponding lubricant should be filled according to the requirements during the test. After the no-load test run, wpwa worm gear reducer, after no abnormal phenomena and tooth surface contact spots meet the requirements, then carry out a load test run.

Common worm gear reducer cooling methods
1. The cooling coil of the equipment in the tank oil pool, the cooling water in the pipe takes away part of the heat of the lubricating oil.
2. The electric fan is cooled, and the electric fan is added on the outgoing shaft of the worm to increase the heat dissipation and reach the cooling.
3. The cooling gear is added to the outside of the worm gear deceleration chassis to increase the cooling surface.
4. Lubricating oil external circulation equipment of worm gear reducer equipment reduces oil temperature.
Worm gear reducer planning In order to improve its application power, the worm gear uses non-ferrous metals as the primary data. The worm generally uses hard steel, so it simply generates large heat during operation, plus the influence of the operating environment temperature. The temperature of the reducer is difficult to control in use. Within the temperature range.
The operating temperature of the worm gear reducer should be controlled at -40 ° C ~ 40 ° C. When the ambient temperature is lower than 0 ° C, it should be heated before starting to fully dissolve the lubricating oil or select a low freezing point lubricating oil.

Analysis of the self-locking property of worm gear reducer
Worm gear reducer is self-locking. When the lead angle of the worm is less than the equivalent friction angle between the teeth of the meshing gear, the worm gear reducer in Linghe District has a self-locking mechanism, which can realize reverse self-locking, that is, the worm gear can only be driven by the worm, but not by the worm gear. Worm. For example, the self-locking worm mechanism used in hoisting machinery, its reverse self-locking can play a protective role!
But not all worm gear reducers have a good self-locking function. For an intelligent worm gear reducer, the self-locking function of the worm gear needs a certain speed ratio to achieve. This is related to the lead angle, and the self-locking property of the worm gear with a small speed ratio is not so obvious. Worm drive is equivalent to helical drive. It is a multi-tooth mesh drive, so the transmission is stable and the noise is very low.
