Double-row self-aligning ball bearings used on reducer features

Dec 19, 2023

The reducer is a device widely used in the field of mechanical transmission. It can reduce the speed of high-speed rotating motors or engines to meet the actual needs of various mechanical equipment. Double-row self-aligning ball bearings are an essential part of the reducer. They have the characteristics of automatically adjusting the axis position, withstanding high loads, high-temperature resistance, corrosion resistance, etc., which can ensure the stability and reliability of the reducer. Today, we, FV, will analyze the double-row self-aligning ball bearings on the reducer.

Structure and characteristics of double-row self-aligning ball bearings

Double-row self-aligning ball bearings comprise inner rings, outer rings, rolling elements, cages, etc. The bearing comprises two main parts: the inner and outer rings. The rolling elements roll between the inner and outer rings. The function of the cage is to prevent the rolling elements from colliding with each other. In double-row self-aligning ball bearings, the inner ring and outer ring have spherical-shaped contact surfaces that adjust the shaft center position to accommodate non-concentricity caused by shaft deflection or manufacturing errors.

The characteristics of double-row self-aligning ball bearings are as follows:

1. Self-aligning function: Double-row self-aligning ball bearings have a self-aligning function that can automatically adjust the misalignment caused by shaft deflection or manufacturing errors. This feature enables double-row self-aligning ball bearings to adapt to loads under various conditions and ensure the regular operation of the bearings.

2. Strong load-bearing capacity: There are oil grooves and holes between the balls and the inner ring of double-row self-aligning ball bearings for lubrication and cooling. This design can increase the bearing capacity and is suitable for bearing radial and specific axial loads.

3. High-temperature and corrosion resistance: Double-row self-aligning ball bearings are usually made of high-temperature and corrosion-resistant alloy steel and can typically work under strict working conditions such as high temperature, high speed, and heavy load.

4. Smooth operation: The design and processing accuracy of the balls and cages of double-row self-aligning ball bearings are very high, which can ensure the stability and noise control of the bearing during operation.

Application of double-row self-aligning ball bearings in reducers

The reducer is a device widely used in various mechanical devices. It can reduce the speed of high-speed rotating motors or engines to meet the actual needs of various mechanical equipment. As an essential part of the reducer, double-row self-aligning ball bearings have the following functions:

Support function: Double-row self-aligning ball bearings can withstand radial and axial loads and provide stable support for the operation of the reducer.

Adjust the axis position: Double-row self-aligning ball bearings have a self-aligning function, which can automatically adjust the non-concentricity caused by shaft deflection or manufacturing errors to ensure the stable operation of the reducer.

Reduce friction and wear: Double-row self-aligning ball bearings are usually made of high-temperature and corrosion-resistant alloy steel, which can work typically under harsh working conditions such as high temperature, high rotation speed, and heavy load, reducing friction and wear.

Reduce noise: Double-row self-aligning ball bearings' design and processing accuracy is very high, which can ensure the stability and noise control of the bearing during operation.

Selection and installation of double-row self-aligning ball bearings
