Gaskets are divided into: flat washer - grade C, large washer - grade A and C, extra large washer - grade C, small washer - grade A, flat washer - grade A, flat washer - chamfer type - Grade A, high-strength washers for steel structure, spherical washers, cone washers, square bevel washers for I-beam, square bevel washers for channel steel, standard spring washers, light spring washers, heavy spring washers, internal tooth lock washers , Internal serrated lock washers, external serrated lock washers, external serrated lock washers, single-ear stop washers, double-ear stop washers, outer tongue stop washers and stop washers for round nuts, etc.
Guangdong Yueluo Hardware Industry Co., Ltd. provides a shaft retaining ring in order to solve the above problems. The plan of Guangdong Yueluo Hardware Industry Co., Ltd. is a shaft retaining ring realized in this way, which is composed of a shaft washer, a torsion spring, a positioning pin and a limit pin. It is characterized in that the shaft washer is provided with two symmetrical distribution gaps. a circular ring, and a groove is provided at the vertical notch on one side, and a stepped through hole is provided on the side notch facet of the groove to cooperate with the limit pin, and the two sides of the groove are provided with a through hole and a locating pin Matching; the limit pin is a stepped short shaft. The beneficial effects of Guangdong Yueluo Hardware Industry Co., Ltd. are simple structure, low production cost, convenient and reliable use.
The defect of the existing press-fit solution is: when the retaining ring is placed in the chamfering section or the guide section of the shaft head, the retaining ring cannot be accurately fixed, and the retaining ring is easy to tilt or fall, especially when the shaft head is located inside the bearing chamber depression, The inclination of the retaining ring will make it difficult to press the retaining ring, affect the production efficiency, and even cause the product to be scrapped.
At present, the commonly used fastener loosening prevention methods generally include non-removable anti-loosening solutions and friction-increasing anti-loosening solutions. The non-removable anti-loosening scheme uses welding, bonding or punch point riveting to change the detachable threaded connection into a non-detachable threaded connection. In the non-removable anti-loosening scheme, the threaded fasteners cannot be reused and the operation is troublesome. It is often used in some important occasions that require high anti-loosening performance without disassembly. The anti-loosening scheme that increases the frictional force uses the method of increasing the frictional force of the bolt (screw) head and the end face of the nut to achieve the purpose of anti-loosening. The anti-loosening solution that increases friction is not limited by space and can be disassembled repeatedly, but the reliability is poor. After a certain period of work, the anti-loosening effect will be reduced due to vibration and other reasons.
