Technical Field
[0001] The invention relates to the technical field of bearing detection and matching, and in particular to a wheel hub bearing axial clearance matching machine. Background Art
[0002] The wheel hub bearing is an important component that connects the wheel and the axle, allowing the wheel to rotate smoothly with minimal friction. The main functions of the wheel hub bearing include bearing weight and providing precise guidance for the rotation of the wheel hub. It can withstand axial loads and radial loads and is a very important component in the car. The design and performance of the wheel hub bearing have a direct impact on the vehicle's driving stability, safety and fuel economy.
[0003] Bearing clearance refers to the amount of movement when the inner ring or outer ring of a bearing is fixed and the unfixed side is moved radially or axially when the bearing is not installed on a shaft or bearing box. According to the direction of movement, it can be divided into radial clearance and axial clearance. The size of the clearance during operation affects the rolling fatigue life, temperature rise, noise, vibration and other performance of the bearing.
[0004] At present, when bearings are assembled in the factory, the pre-selection and sorting of the inner and outer rings of the bearings are carried out separately, and after the selection, the assembled finished products are also measured by another device. At present, when the wheel hub bearings are assembled in the factory, the wheel hub bearings and the bearing inner rings are measured by two devices. This results in many sizes of bearing inner rings that need to be sorted and a large material warehouse. Since they are not together, when sorting deviations are found in subsequent assembly, it is easy to cause a large number of intermediate products, resulting in a large amount of subsequent rework.
