ball bearings are widely used important mechanical basic parts, which are widely used in various fields of national economy and national defense.
What are the installation principles of ball bearings?
What is the assembly method of ball bearing?
What should we pay attention to after the ball bearing is installed?
Assembly principle of ball bearing: According to the bearing structure, size, working conditions and the matching nature of bearing components, the pressure during assembly should be directly applied to the end face of the ring to be matched, and pressure is not allowed to be transmitted through the rolling elements. The assembly of ball bearings generally includes press-fit assembly method, temperature difference assembly method and power frequency induction heater.
1. The ball bearing should not be removed from the machine. If it must be removed, the correct tool and method should be used.
2. Before assembling the ball bearing, the appropriate cleaning agent and method should be selected according to the anti-rust method of the ball bearing.
3. Before assembly, use the inner and outer micrometers to check the inner diameter of the bearing sleeve and the diameter of the journal, and the matching tolerance must meet the requirements of the drawing.
4. The ball bearing is installed in the split bearing seat. There should be no gap between the joint surface of the bearing cover and the bearing seat, but there should be a certain gap between the outer ring of the bearing and the tile mouth on both sides of the bearing seat. .
Before starting the assembly of the ball bearing, it is necessary to clean the rolling bearing first to keep it clean and tidy; then inspect the rolling bearing and assemble it according to its assembly requirements.
1. First, remove the residual grease and anti-rust oil in the ball bearing.
2. Rinse the ball bearing with kerosene first, then with gasoline, and dry it with a clean cloth.
3. Other cleaning agents can also be used to clean the bearing, and the bearing is cleaned with a cloth.
4. Remember, do not use dirty oil or dirty cloth, cotton yarn to clean or dry the ball bearing.
All kinds of radial bearings, needle roller bearings and helical roller bearings of ball bearings must rotate flexibly after being assembled. After the bearing is assembled with grease, 65%~80% of the cavity volume of clean grease is injected into the bearing cavity. For the bearing lubricated with thin oil, it is not allowed to inject grease.
After the ball bearing is installed, the axial clearance and axial preload (axial pre-interference) that should be adjusted should be in accordance with the bearing standards or equipment technical documents.
The ball bearing plays an irreplaceable role in life. Shandong Xuanye Precision Machinery Co., Ltd. has been focused on ball bearing for several years. They will make every effort to meet the needs of users.
