Problems solved by technology

Under high temperature operation, heavy load, long-term operation of lubricating oil precipitation, grease failure, resulting in no lubrication state operation, at the same time, the elastic deformation caused by the instantaneous impact force, resulting in fatigue damage to the bearing (the characteristic of fatigue damage is the peeling of the sliding surface in the groove) , although the bearing can rotate, but dry grinding on the damaged raceway, the beating sound is loud
[0004] Especially in some occasions such as permanent magnet motors and variable frequency speed regulating motors under long-term continuous operation under heavy load, high temperature, and high humidity conditions, the bearings cannot adapt to the harsh working environment during use, causing premature fatigue damage to the bearings. Accelerated bearing fatigue damage with momentary impact forces

Embodiment Construction

[0082] In order to better understand the present invention, the content of the present invention will be further clarified below in conjunction with the examples, but the content of the present invention is not limited to the following examples, and the examples should not be regarded as limiting the protection scope of the present invention.

[0083] The invention has been improved from the four aspects of technical design, manufacturing process, bearing lubricating grease selection, and bearing manufacturing materials. The improved bearing can significantly extend the service life, and is wear-resistant and high-temperature resistant.

[0084] (1) The working clearance Gr of the bearing is calculated and selected according to the following steps:

[0085] ①Calculate the maximum contact stress according to the maximum load:

[0086]

[0087] Where: Pmax — maximum Hertz contact stress;

[0088] e a — Coefficient of the major axis of the contact ellipse;

[0089] e b — Coefficient of the...

Abstract

The invention discloses a long-service-life high-temperature-resistant textile motor bearing, and belongs to the technical field of high-precision special bearing manufacturing. The long-service-lifehigh-temperature-resistant textile motor bearing is improved in the four aspects of technical design, manufacturing process, bearing lubricating grease selection and bearing manufacturing material, the service life of the improved bearing can be obviously prolonged, and the improved bearing is wear-resistant and high-temperature-resistant. According to the long-service-life high-temperature-resistant textile motor bearing, the working clearance Gr of the bearing is scientifically designed; the mounting clearance and the change clearance of inner and outer rings caused by temperature change areconsidered; and the problems that when the maximum rolling body load of a bearing raceway bearing region is increased during working operation, friction torque and temperature rise are increased dueto clearance change caused by elastic deformation and the bearing adhesion or damage due to fatigue occur too early are mainly solved, so that the service life of the bearing is greatly prolonged.

Description

Technical field [0001] The invention belongs to the technical field of high-precision special bearing manufacturing, and specifically relates to a long-life, high-temperature-resistant textile motor bearing. Background technique [0002] In recent years, textile machinery and equipment have become increasingly stringent in the environment and conditions applicable to rolling bearings, and at the same time they have become more diverse. Textile machinery motors FYQ and FYQQ use harsh working conditions, and the bearings used in the motors must meet the requirements of special working conditions. At the same time, the motor is generally installed in a relatively closed position at the bottom of the machine tool, with only one exhaust window on the side. The internal temperature is high and the humidity is high. The radial load is large (the four belts are tight and cannot be pressed), and there will be an instant impact when starting. Because of the harsh operating conditions, t...
