Description

Technical Field

[0001] The utility model relates to a shaft housing with a built-in reinforcement structure, belonging to the technical field of shaft housings. Background Art

[0002] The shaft housing usually refers to a component installed outside the rotating shaft to protect the shaft and bearings, and also plays a fixing and supporting role.

[0003] A Chinese patent publication (publication number: CN 219911590 U) discloses a balancing shaft housing, wherein a leaf spring groove, a leaf spring center bolt positioning hole and a bolt hole are respectively provided on the top surface of the shaft housing body, and a stopper is fixedly installed at the left and right ends of the bottom of the shaft housing body. By setting a balancing shaft housing, the contact between the outer surface of the nut and the stopper is achieved by utilizing the structural design of the stopper, thereby achieving the purpose of limiting the movement of the nut, ensuring the fixing effect and connection efficiency between the shaft housing and the leaf spring, and facilitating the subsequent use of the shaft housing;

[0004] Although the above-mentioned device realizes the contact between the outer surface of the nut and the stopper, thereby achieving the purpose of restricting the movement of the nut, ensuring the fixing effect and connection efficiency between the shaft housing and the leaf spring, and facilitating the subsequent use of the shaft housing, the above-mentioned patent still has certain defects. When the shell is installed, the two shells are connected together only by a screw, and the operation is cumbersome. After long-term use, there is a situation where the screw wire is removed and cannot be disassembled. In addition, the existing shell protection effect is weak. The shell is prone to rupture after a long period of use, thereby damaging the internal shaft parts and reducing the service life of the shaft parts.

[0005] To this end, a shaft housing with a built-in reinforcement structure is proposed. Utility Model Content
