How To Improve Working Efficiency Of Worm Gear Reducer ?
In order to improve efficiency of the worm gear reducer, the worm wheel is non-ferrous metal , the worm is hard steel. Because of sliding grinding drive, it will produce high heat to make the thermal expansion between the parts and the seal in the process of operation.So as to produce a gap in the mating surface and the oil leakage with the temperature rise . There are four main reasons: whether the collocation of the material is reasonable; the surface quality of the grinding surface;whether the choice and the added amount of lubricating oil is correct; the assembly quality and use environment.
The worm gear worm reducer generally adopts tin bronze. The matching worm material is generally hardened with 45 steel to HRC45155, and often uses 40C: quenching HRC50155. After the worm grinder grinding to roughness RaO.8fcm, worm gear reducer is in normal operation, the worm gear is like a hardened “”file””, filing the worm wheel continuously, making the worm wheel wear. Generally speaking, this wear is very slow, like a factory some worm gear reducer can be used for more than 10 years. If the wear speed is fast, it is necessary to consider whether the selection of the worm gear reducer is correct, whether there is overload operation, the material of the worm gear, assembly quality or use environment and other reasons.
Transmission small inclined gear grinding, generally occurs on the vertical mounted worm gear reducer, mainly related to the added amount of lubricating oil and the choice of lubricating oil. When vertical installation, it is easy to cause insufficient amount of lubricating oil. When the worm gear reducer stops running, the transmission gear oil between the motor and the worm gear reducer loses, the gears can not get due lubrication protection, and no effective lubrication in the start or operation process leads to mechanical wear or even damage.
