Structure of rolling bearing

Views:3     Author:Site Editor     Publish Time: 2020-11-19      Origin:Site

Bearings are all around us and have a wide range of uses.

Take a car as an example. Generally, 100 to 150 bearings are used in a car.
Not only cars, vehicles (such as trains, airplanes, ships, etc.), household appliances (such as washing machines, refrigerators, air conditioners, vacuum cleaners, etc.), office appliances (such as photocopiers, computers, etc.), children's electric toys, power tools, machine tools, etc. , Even satellites, there are bearings. Bearings play an important role in improving mechanical operation efficiency and energy saving. Although the bearing runs silently inside the machine, it is an important part to keep the machine stable and functioning.

Ball bearing 

roller bearing (rolling bearing)

The basic structure of "rolling bearing" is very simple and consists of four parts.

Outer ring

Inner ring

Rolling element

balls or rollers between the outer and inner rings


Positioning parts for rolling elements

The basic function of the bearing is to "reduce mechanical friction". There are three major benefits of reducing friction:

1. Improve the working efficiency of machinery.

2. Extend the service life of the machine.

3. Prevent seizure and reduce mechanical failure.

Bearings can reduce friction, improve transmission efficiency, and contribute to energy saving.

The relationship between ball screw preload and accuracy

The relationship between the pre-pressure of the ball screw and the load of the screw is mainly used for gap adjustment. If high precision is required, the pre-pressure should be increased accordingly, but it should not be too large, otherwise it will cause high temperature and reduced efficiency.

Ball screw drive torque

What is the ball screw drive torque? How should this torque be calculated? The torque of the mechanical components is called the driving torque of the ball screw. The ball screw will produce a certain degree of torsional deformation under the action of torque. Torque is the basic load form of transm

Ball screw axial load

SCREWTECH ball screw mechanisms are usually used together with guide components (such as linear guides, linear bearings). The ball screw mechanism only provides the axial force required by the ball nut to make the worktable move in the direction of linear motion, and the worktable as the load and th
