In the WPEDX80-135,WPEDX80-147,WPEDX100-155,WPEDX120-175,WPEDX135-200 worm gear reducer, the idle shaft worm gear reducer is equipped with a helical gear reducer at the input end of the worm gear reducer. Multi-stage reducer can get very low output speed. It is a combination of helical gear stage and worm gear stage, which is more efficient than pure single-stage worm gear reducer. Small vibration, low noise, the worm wheel can generally be made of tin bronze, the matching worm material is generally hardened to HRC45-55 with 45 steel, 40C: hardened to HRC50-55, and ground to roughness RaO with a worm grinder. 8fcm. When the reducer is in normal operation, the worm is like a hardened "file", which constantly files the worm gear, causing the worm gear to wear. Generally speaking, this wear is very slow, and some reducers can use 10 reducers, which are usually designed according to constant torque, infrequent start and stop, and normal temperature conditions.
Worm reducer Precautions for worm reducer: 1. When installing the reducer, attention should be paid to the central axis of the transmission from the middle to the middle. The error must not be greater than the compensation of the coupling used. It is beneficial to the center, which can prolong the service life and obtain ideal transmission efficiency.
2. When installing transmission parts on the output shaft, it is not allowed to strike with a hammer. Usually, the internal threads of the assembly fixture and the shaft end are used to press the transmission parts with bolts, otherwise the internal parts of the reducer will be damaged. It is best not to use rigid fixed couplings, because improper installation of such couplings will cause unnecessary external loads, and in severe cases, it will cause early damage to the bearings and even break the output shaft.
3. The reducer should be firmly installed on a stable foundation or base, the oil in the oil drain tank should be able to be drained, and the cooling air should circulate smoothly. The foundation is unreliable, vibration and noise are generated during operation, and bearings and gears are damaged. When the transmission coupling has protrusions or uses gears and sprockets for transmission, additional protection devices should be considered. When the output bearing is subjected to a large radial load, the reinforced type should be selected.
4. Install the device according to the regulations to ensure that the staff can easily access the oil mark, exhaust plug and oil drain plug. After the installation is in place, the accuracy of the installation position should be comprehensively checked in sequence, and the reliability of the compression of each fastener should be rotated flexibly after installation.
