A high-strength washing machine high-speed motor bearing

Abstract

The invention discloses a high-strength washing machine high-speed motor bearing and relates to the field of bearings. The high-strength washing machine high-speed motor bearing comprises a bearing body. The bearing body is sequentially provided with an outer ring, a rolling body, a retainer, a first inner ring, a second inner ring and an inner shaft sleeve from outside to inside. The first inner ring and the second inner ring are arranged side by side. The rolling body comprises a first cylindrical roller arranged on the outer side of the first inner ring, a second cylindrical roller arranged on the outer side of the second inner ring, a first rolling ball arranged on the inner side of the first inner ring and a second rolling ball arranged on the inner side of the second inner ring. A fastening portion is arranged on the outer side of the inner shaft sleeve. The fastening portion is used for fixing the first inner ring and the second inner ring. The inner side of the inner shaft sleeve is provided with a toothed groove which is used for fixing the bearing body to a rotating shaft. By means of the design that the rolling balls are combined with the cylindrical rollers, the effect of increasing the load of the bearing is well achieved, the largest rotating speed of the bearing can be greatly improved due to the design of a good lubricating system and a nylon retainer, the service life of the bearing is prolonged, and the requirement for the high-strength and high-speed bearing of a washing machine is met.

Description

technical field [0001] The invention relates to the field of bearings, in particular to a high-strength washing machine high-speed motor bearing. Background technique [0002] 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 limitations of the shape and material of the roller, it is difficult to avoid the wear of the outer frame and the inner frame of the roller. At the same time, in many equipment, the bearing also bears a large radial impact. Rollers...
