Description

Bearing rubber seat and air conditioner indoor unit

Technical Field

The application relates to the technical field of air conditioner accessories, in particular to a bearing rubber seat and an air conditioner indoor unit.

Background

The bearing rubber seat is widely applied to the split internal machine of the air conditioner, is mainly matched with a fan bearing ball for connecting a bottom shell and a fan blade, ensures that the through-flow fan blade for the internal machine can run at high speed, and can achieve the effects of vibration reduction and noise reduction. The bearing rubber seat has the advantages that the bearing rubber seat belongs to a large number of conventional used materials, has liquid resistance and high temperature resistance, and must achieve the effects of vibration and noise reduction due to the fact that the steel shaft of the through-flow fan blade is of a stainless steel structure and is matched with the steel shaft, the bearing rubber seat is generally used on a split internal machine of an air conditioner, the effect of the noise vibration problem of the whole machine of the internal machine is obvious, and the application effect is temporarily free from other product substitutes.

Because the outer surface of the fan bearing ball is smooth, the whole size of the inner cavity needs to be relatively consistent with the outer diameter of the fan bearing ball in order to ensure that the inner cavity of the fan bearing ball is well matched with the fan bearing ball, but in the process, the fan bearing ball is over-tightly assembled, and noise is generated in the process of running and matching with a steel shaft of the cross-flow fan blade. The main reasons are as follows: the inner cavity of the bearing rubber seat is oversized, a fan bearing ball is assembled in the inner cavity and shakes, and a blade steel shaft is easily clamped after being inserted, so that the cross-flow blade of the inner machine does not run, and the air of the whole machine does not flow out; the size of the inner cavity of the bearing rubber seat is too small, the fan bearing balls are matched with the bearing rubber seat too tightly after being assembled, and the fan bearing and the bearing rubber seat rub to generate noise in the high-speed operation process of the fan blade steel shaft.
