Air lubrication and types of eccentric roller bearings

1,682 Published by admin1 Nov 08,2018

eccentric roller bearings is a very important bearing in the cycloid reducer. The original eccentric bearing consists of three parts: an eccentric sleeve and two 502 series cylindrical rollers. The eccentric sleeve and the inner ring of the bearing are integrated to form an eccentric bearing. The eccentric bearing mainly comprises an outer ring, an inner ring, a rolling body flower basket and a rolling body, wherein the inner hole of the inner ring is an eccentric hole, and a longitudinal key groove is arranged on the inner side wall of the eccentric hole.

The eccentric bearing has the advantages of simple structure and convenient use, can realize the eccentric function without the eccentric shaft, greatly simplifies the eccentric mechanism, and at the same time makes the machining of the eccentric mechanism labor-saving, time-saving and easy to assemble, and reduces the manufacturing cost of the eccentric mechanism.

 eccentric roller bearings is a roller bearing., which is composed of two or more roller bearings with eccentric sleeves. This type of bearing is also called an integral eccentric bearing.
eccentric bearings can be divided into two categories: one is a double-layer double-row tapered roller eccentric bearing, and the other is a double-layered raceway with an inner and outer eccentric negative clearance cylindrical roller bearing unit.
The characteristics of eccentric bearing: the eccentric function can be realized without the eccentric shaft, and the eccentric mechanism is greatly simplified.

Air lubrication of eccentric roller bearings
In eccentric bearings, oil and gas lubrication is much smaller than cyclic oil supply in terms of the effect of lubricant viscosity on bearing temperature rise. However, under the same conditions of oil supply, when the viscosity is high, the temperature rise is slightly increased. The usual oil and gas lubrication at 40 ° C, the role of the overall eccentric bearing, the use of oil with a viscosity of 10 - 3Cmrn2 / s.
Gas lubrication is a new lubrication method with many characteristics. The advantages of the whole eccentric bearing are used in bearings with more sliding, such as angular contact bearings. The dmn value can reach about 1.5 million.

How to choose the types of imported eccentric roller bearings?
In order to prevent the eccentric angle from being oversized, the self-aligning ball bearing, the whole eccentric bearing manufacturer, the self-aligning roller bearing, or the self-aligning bearing seat is a better choice.嗓 audio frequency and torque, the overall eccentric bearing, dynamic bearings are produced according to high-precision scale, so the voice and torque are small. Deep groove ball bearings and cylindrical roller bearings are used in combination for low noise and low torque.
