[0002] The cam rotor pump is a positive displacement pump widely used in applications where high viscosity, solid particles or special properties of fluid need to be handled, such as food industry, chemical industry, petroleum, environmental protection and other fields. Due to its complex and changeable working environment, the reliability and durability of the pump are extremely high, especially the key component of the pump - bearings, whose installation quality directly affects the performance and life of the pump. As a key component supporting the rotation of the rotor, the bearing bears the radial and axial loads generated by the pump during operation, ensuring the smooth and low-vibration operation of the rotor. The correct installation method is the prerequisite for ensuring the service life of the bearing and the working efficiency of the pump. The bearings are installed on the rotor shaft of the pump, usually close to both ends of the pump. These bearings support the rotor shaft, enabling it to rotate inside the pump casing, while reducing friction and bearing the radial and axial loads generated by the pump during operation. Such bearings can be ball bearings, roller bearings or plain bearings, etc. The specific type depends on the design requirements and working conditions of the pump.

[0003] The traditional method of pressing bearings by hand or using simple tools is difficult to achieve precise installation requirements, which may cause the bearings to be too tight or too loose, leading to problems such as early bearing failure, reduced pump efficiency, and increased noise.
