Novel self-lubricating washing machine high-speed motor bearing

Abstract

The invention discloses a novel self-lubricating washing machine high-speed motor bearing, and relates to the field of bearings. The novel self-lubricating washing machine high-speed motor bearing comprises a bearing body, wherein the bearing body is sequentially provided with an outer ring, rolling bodies, retainers, an inner ring I, an inner ring II and an inner shaft sleeve from outside to inside, wherein the inner ring I and the inner ring II are arranged in parallel; each rolling body comprises a cylindrical roller I and a cylindrical roller II which are respectively arranged at the outersides of the inner ring I and the inner ring II and a ball I and a ball II which are respectively arranged at the inner sides of the inner ring I and the inner ring Ii; a fastening part is arranged at the outer side of the inner shaft sleeve; the fastening part is used for fixing the inner ring I and the inner ring II; tooth-shaped grooves are formed in the inner side of the inner shaft sleeve; the tooth-shaped grooves are used for fixing the bearing body on a rotating shaft. According to the novel self-lubricating washing machine high-speed motor bearing disclosed by the invention, through the design of the balls and the cylindrical rollers, a function of increasing the load of a bearing is well achieved; through the design of a good lubricating system and nylon retainers, the maximum rotating speed of the bearing can be greatly increased, the service life of the bearing can be prolonged, and the requirements on the high-strength and high-speed bearing of a washing machine can be met.

Description

[0001] The present invention is an application number: 2017100088694, application date: 2017-01-06, and name of the invention: a divisional application for a high-strength washing machine high-speed motor bearing. technical field [0002] The invention relates to the field of bearings, in particular to a novel self-lubricating washing machine high-speed motor bearing. Background technique [0003] With the improvement of people's performance requirements for washing machines, there is a high requirement for the rotational speed of the motor in the washing machine. High speed means high efficiency, which can greatly save the washing time of the washing machine. However, the problem of reduced bearing life caused by high speed cannot be ignored. Traditional bearings are composed of a simple outer frame, inner frame and rollers. The rollers directly contact with the The friction between the outer frame and the inner frame realizes the rotation of the bearing. Due to the limitat...
