Oscillator measurement device of drum washing machine outer barrel and bearing assembly

Abstract

The invention relates to a measuring instrument, and particularly relates to an oscillator measurement device of a drum washing machine outer barrel and a bearing assembly. The oscillator measurement device comprises a pedestal and a support, a belt, a motor, a core shaft, an acceleration transducer and a measurement and control electrical cabinet, wherein the pedestal is provided with the support; the motor is arranged in the support, a through hole is formed on the center of the top of the support, and the core shaft stretches into the support along the through hole and is connected with the motor through the belt; and the upper edge of the support is provided with the acceleration transducer, the inductance end of the acceleration transducer faces to the core shaft, and the acceleration transducer is connected with the measurement and control electrical cabinet. The oscillator measurement device of the drum washing machine outer barrel and the bearing assembly provided by the invention has the advantages of simple structure, exact vibration test and simple method, and is beneficial to quantity production of the outer barrel and the bearing assembly.

Description

technical field [0001] The invention relates to a measuring instrument, in particular to a vibration measuring device for an outer tub and a bearing assembly of a drum washing machine. Background technique [0002] The vibration of the whole machine caused by the drum washing machine rotating at high speed is one of the main indicators for evaluating the quality of the washing machine. Generally, the inner tub of the washing machine is directly connected to the rotating shaft, and a pair of rolling bearings are installed on the outer tub to support the rotating shaft. During the installation process of the pair of bearings, they are pressed into the outer barrel bushing by external force, and the outer ring of the bearing and the bushing are an interference fit. During the bearing press-in process, due to changes in fit size, positioning, and press-in force, the bearing outer ring, cage, inner ring, and even rollers may be deformed, resulting in vibration and noise during h...

AI Technical Summary

Problems solved by technology

At present, the bearing is only rotated by hand after the bearing is pressed into the outer tub. Judging by feeling, the quality of the components cannot be effectively controlled, which may easily cause overall quality problems of the washing machine.
