Low-noise decelerator for washing machine

Abstract

A low noise reducer for the washing machine relates to the reducer technology area. The driving assembly is stable axes. It consists of the case, input axes, driver, driven wheel, medium wheel, open tighten wheel and output wheel, and all the part connects together by the double sides wedge strips, the driver fixes on the input axes and the driven wheel fixed on the output axes, and the medium wheel, open tighten wheel and output axes install on the case actively. The driver, driven wheel, medium wheel and open tighten wheel has multi wedge groove where has the multi wedge strip. The open tighten wheel has two types such as fixed open tighten wheel and automatic open tighten wheel. This reducer for the washing machine' s configuration is simple, tighten, oil saving and the anti-bearing isgood, it can simply the sealing configuration, the maintenance is economical, the part is firmly and the lifetime is long, the instantaneous speed is stable, the driving efficiency is high, the anti-crash is good. It can reduce the noise, which is smaller than 50dB when working at unloading condition.

Description

technical field [0001] The technical solution of the invention relates to the technical field of washing machine speed reducers. Background technique [0002] The reducer of the washing machine is the main generating part of the noise of the washing machine. Conventional pulsator washing machine reducer is generally spur gear fixed shaft transmission or planetary gear transmission. The input shaft is decelerated through the reducer to drive the pulsator or at the same time drive the inner tub to rotate at a set ratio, but the transmission stability of conventional gears is poor. The noise is relatively loud; although the reducer driven by the belt can reduce the noise, but because the reducer of the washing machine has a compact structure, a large transmission ratio, and the drive shaft is vertical to the ground, it is difficult to use the traditional V-belt, round belt and toothed belt transmission. Under this condition, it can transmit relatively large power stably, and a...

Problems solved by technology

Conventional pulsator washing machine reducer is generally spur gear fixed shaft transmission or planetary gear transmission. The input shaft is decelerated through the reducer to drive the pulsator or at the same time drive the inner tub to rotate at a set ratio, but the transmission stability of conventional gears is poor. The noise is relatively loud; although the reducer driven by the belt can reduce the noise, but because the reducer of the washing machine has a compact structure, a large transmission ratio, and the drive shaft is vertical to the ground, it is difficult to use the traditional V-belt, round belt and toothed belt transmission. Under this condition, it can transmit relatively large power stably, and at the same time meet the standard requirements of the national standard for household electric washing machines on the working noise of washing machines.
