Steel-based bushing for pin shaft sleeving

Abstract

The invention discloses a steel-based bushing for pin shaft sleeving. The steel-based bushing for pin shaft sleeving comprises a bushing body, a sliding adjusting ring and a telescopic front sleeve, the sliding adjusting ring is mounted in the middle of the bushing body, an assembling ring is arranged inside the sliding adjusting ring in a penetrating mode, a rear welding ring is welded to one endof the assembling ring, a first extrusion-supporting frame is arranged inside the rear welding ring, a second extrusion-supporting frame is arranged on one side of the first extrusion-supporting frame, the first extrusion-supporting frame is provided with a spring, one end of the spring is fixedly connected with a connecting plate, a plurality of protruding blocks are welded to the connecting plate, threads are arranged on the telescopic front sleeve, a sleeve head is arranged at one end of the telescopic front sleeve, a damping disc is longitudinally arranged at one end of the sleeve head, and a penetrating groove of a hollow structure is formed inside the telescopic front sleeve. The steel-based bushing is convenient to use, firm and durable.

Description

technical field [0001] The invention relates to a steel-based bushing used for pin shaft socketing. Background technique [0002] With the rapid development of people's living standards, bushings are more and more widely used in people's lives. Bushings refer to ring sleeves that act as pads. There are many kinds of bushings with different appearances and materials. Bushings are mainly used For the socketing of the pin shaft, it has a great effect on the fixing and sealing of the pin shaft. Steel-based bushings refer to bushes made of steel materials. [0003] However, the existing steel-based bushings for pin sockets have many disadvantages, such as the steel-based bushes are not firmly fixed to the pins after being inserted into the pin shafts, and the gap between the bushes and the pin shafts is insufficient. The frictional resistance is low, the pin is easy to slide and loosen in the bush, the wear resistance of the bush is poor, the length of the bush is fixed, the ad...

Problems solved by technology

[0003] However, the existing steel-based bushings for pin sockets have many disadvantages, such as the steel-based bushes are not firmly fixed to the pins after being inserted into the pin shafts, and the gap between the bushes and the pin shafts is insufficient. The frictional resistance is low, the pin is easy to slide and loosen in the bush, the wear resistance of the bush is poor, the length of the bush is fixed, the adaptability of the bush is not wide enough, and it can only be used for the socket of the same type of pin. After the pin shaft is inserted into the bushing, the vibration and friction loss of the pin shaft and the connecting parts are large.
