Gearmotors Lifetime lubricated compound gearboxes are filled with synthetic oil at the manufacturer's factory. In addition, gearboxes are usually supplied without oil, with filler plugs and drain plugs. The number of reducer lubricants listed in this catalog is only an estimate. Set the position of the oil level plug according to the installation position specified in order to ensure the correct oil, reducer oiling amount should be determined according to different installation methods. If the transmission power exceeds the thermal capacity of the reducer, an external cooling device must be provided Reduction ratio: The ratio of input speed to output speed. Series: the number of planetary gear sets. The general maximum can reach three, the efficiency will be reduced. Full load efficiency: In the case of maximum load (fault stop output torque), reducer transmission efficiency. Working life: reducer in the rated load, the rated input speed of the cumulative working hours. Rated torque: is the rated life of the allowed long-term operation of the torque. When the output speed of 100 rev / min, the life of the reducer is the average life expectancy above which the average life reducer will be reduced. When the output torque more than twice the reducer failure. Noise: Unit dB (A), this value is the actual input speed 3000 r / min, without load, 1 meter away from the measured value when the reducer. Hysteresis: the input is fixed, the output clockwise and counterclockwise rotation, when the output plus or minus 2% rated torque, the reducer output by a tiny angular displacement, the angular displacement is the return gap. The unit is "points", once the 1/60. Gear reducer lubrication and maintenance: Put into operation the gear reducer recommended models and values ​​of grease. Reducer lubricated with oil. For vertically mounted gearheads, additional lubrication is used as the lubricant may not be able to guarantee a reliable lubrication of the uppermost bearing. Prior to operation, inject a suitable amount of lubricant into the reducer. The viscosity of the lubricant should be selected according to the following list. Gearboxes are usually equipped with oil fill holes and drain plugs. Therefore, when ordering reducer must specify the installation location. The table below lists the make and model of lubricants recommended for general use. Note: For unconventional working conditions, consult your manufacturer. Working oil temperature can not exceed 80 ℃.
