Lubrication for gear reducer
The lifetime lubrication combination of the gear reducer is injected with full synthetic oil at the factory. In addition, the reducer supplies don't provide lubricant, which have the fill plug and oil drain plug. Reducer lubricant number listed in this sample is only an estimate. According to the installation location and the location of the oil level plug specified in the order to ensure proper oiling. The reducer injecting fuel should be determined according to the different installation methods. If the transmission power exceeds the thermal capacity of the reducer, then you must provide an external cooling device.
The indicators of gear reducer
Reduction ratio: input speed and output speed ratio Number of stages: It is the number of planetary gears. Generally can reach three and the efficiency will be reduced。 Full load efficiency: The transfer efficiency of the reducer machine at the maximum load (stop at failure and output torque).。 Working life: It is the cumulative working time for reducer at rated input speed under rated load. Rated torque: It is the torque for long-term operation allowed by the rated life. When the output speed is 100 rev / min, the life of gear reducer is the average life and the average life expectancy will be reduced when the expectancy of the reducer exceeds this value. The reducer will fail when the output torque is more than twice as the speed. Noise: in decibels dB (A), this value is the values being measured at the input speed of 3000 rev / min, with no load at distance 1 m away from the reducer. Backlash: fix the input terminal, make the output terminal rotate clockwise and counterclockwise, when the output withstand plus or minus 2% of the rated torque, the output of the reducer terminus of a small angular displacement, the angular displacement is the backlash. The unit is the "sub", which is the 1/60.
The gear reducer lubrication and maintenance
Install the proposed model and the value of lubricating grease in the reducer before putting into operation. For the vertical installed reducer, in view of the lubricating oil may not be able to guarantee reliable lubrication on the top, we need to use other lubrication measures. Inject the right amount of lubricating oil into the gear speed reducers before running, lubricating oil viscosity based on the following list to choose. Reducer is usually equipped with the filling hole and drain plug. Thus the installation location must be specified when ordering reducer.
Notes:
For the application of unconventional working conditions, please consult the manufacturer's advice. Working oil temperature must not exceed 80 ℃.
