Bearings and air conditioners

Abstract

The invention provides a bearing. The bearing comprises a base ring, an upper rotation support, a lower rotation support and a motion part, wherein the inner wall of the base ring axially extends to form a stop ring; the upper rotation support and the lower rotation support are annular and arranged on the stop ring in a sleeving mode correspondingly; the lower rotation support is arranged on the lower portion of the upper rotation support; and the motion part is arranged between the upper rotation support and the lower rotation support. The invention further relates to an air conditioner. According to the bearing and the air conditioner, the functions of a regular bearing are achieved, and cost is low, so that the object of reducing production cost is achieved; the windproof effect of the bearing is improved, and the application range is wide; and the bearing is applied to the air conditioner for achieving rotation of the head of the air conditioner, the aim of bilateral wind sweeping of the air conditioner is achieved, and wind leakage at the side wall of the bearing is further reduced.

Description

technical field [0001] The invention relates to the refrigeration field, in particular to a bearing and an air conditioner. Background technique [0002] In general, the plastic bearing structure generally follows the traditional bearing structure. The plastic bearing structure includes bearing inner ring, outer ring, ball, cage and oil seal ring. Its form is relatively fixed and simple, and it is mainly used for connections with small force and unlimited rotation. Some parts cannot be adapted to rotating connections with special sealing requirements. Especially for the situation where a fixed rotation angle range is required, the existing plastic bearings have relatively large limitations. Contents of the invention [0003] Based on this, the purpose of the present invention is to provide a bearing and an air conditioner, which realizes the function of an ordinary bearing, and has a lower cost, achieves the purpose of reducing production costs, improves the air leakage p...
