Embodiment 1

[0043] Self-lubricating anti-cold welding light-duty self-locking nut 22, including a sealing locking ring 1 and a self-locking nut body 2.

[0044] First, thread the connecting bolt 21 through the connected part 20 to the self-locking nut 22 and screw the hexagonal wrenching surface 15 of the self-locking nut 22 to achieve the required pre-tightening force. The installation process is now complete. like Figure 4 shown. The design of the lightening groove 9 effectively reduces the weight of the self-locking nut. The sealing and locking ring 1 is closed and fixed in the self-locking nut body 2 through the stamping and bending deformation of the nut body end face 6, and the sealing and locking ring 1 is plastically deformed to obtain a locking torque and a rational sealing effect at the same time. The organic combination of metal materials and non-metal materials can effectively prevent cold welding.

Abstract

The invention discloses a self-lubricating cold welding preventing light self-locking nut and manufacturing and use methods thereof. The self-locking nut comprises a self-locking nut body (2) and a sealing locking ring (1) used for being mounted in the self-locking nut body (2) and generating locking torque through plastic deformation. The structural design weight of the self-locking nut is minimized, the locking torque can be controlled, meanwhile, an ideal sealing effect is obtained, and cold welding bonding between the nut and a bolt after assembly is effectively prevented. High safety reliability is achieved, mechanical performance is stable, and maintenance is convenient.

Description

technical field [0001] The invention relates to a fastening connection assembly in the technical field of mechanical processing, in particular to a self-lubricating anti-cold welding light-weight self-locking nut and its manufacturing and using methods. Background technique [0002] In the design of mechanical connection fasteners, there are more and more high-end fasteners with multi-functionality, small size, light weight, high strength, self-lubricating anti-cold welding, and good sealing. This type of fastener has high technical requirements, complex structure, difficult process and expensive price. Contents of the invention [0003] The object of the present invention is to provide a self-lubricating anti-cold welding light-duty self-locking nut and its manufacturing and using methods to solve the problems of high technical requirements, complex structure, difficult process and high price of fasteners in the prior art. [0004] The present invention is achieved like ...
