Tooth-shaped gasket for preventing following rotation of bolt and high-strength bolt connecting pair

Abstract

The invention discloses a tooth-shaped gasket for preventing bolt following rotation and a high-strength bolt connecting pair. The tooth-shaped gasket comprises a gasket body, and radial teeth in the radial direction are arranged on the two end faces of the gasket body correspondingly; the radial tooth profiles comprise a plurality of outer tooth profiles extending inwards from the outer circle face of the gasket along the end face and a plurality of inner tooth profiles extending outwards from the inner hole of the gasket along the end face, the outer tooth profiles and the inner tooth profiles are arranged in a staggered and spaced mode, and the interval between every two adjacent outer tooth profiles and inner tooth profiles is small. The outer tooth profiles and the inner tooth profiles are arranged densely, and the number is large. By the adoption of the gasket, in the tightening process of applying torque to a bolt and a nut in a matched mode, the situation that the bolt and the gasket rotate along with the bolt is avoided, the nut can be reliably tightened, the assembling reliability and the equipment installation quality are guaranteed, and therefore the equipment safety is guaranteed. The device is particularly suitable for outdoor environments with severe use environments and places with severe working conditions on working sites and high working difficulty.

Description

technical field [0001] The invention relates to the technical field of bolt connection structures, in particular to an anti-bolt heel-tooth-shaped washer and a high-strength bolt connection pair. Background technique [0002] In the prior art, when some high-strength bolt connections are assembled, flat washers are usually assembled under the bolt heads. The problem with using flat washers is that in the process of applying torque, the bolts and flat washers will often rotate together, which will cause the set value to be unstable, which will lead to assembly failure and even affect the performance of the equipment. Installation quality affects personal and equipment safety. In addition, such high-strength bolted joints are often used outdoors, where the environment is harsh, and the working conditions on the job site are relatively harsh, making the operation difficult. If the assembly failure occurs due to follow-up, there are likely to be potential safety hazards. At th...

The problem with using flat washers is that in the process of applying torque, the bolts and flat washers will often rotate together, which will cause the set value to be unstable, which will lead to assembly failure and even affect the performance of the equipment. Installation quality affects personal and equipment safety

In addition, such high-strength bolted joints are often used outdoors, where the operating environment is harsh, and the working conditions on the job site are relatively harsh, making the operation difficult

If assembly failure occurs due to follow-up, there may be potential safety hazards. At the same time, when replacing the connection pair, the operation is cumbersome, and the cost of labor, spare parts and delays in the construction period will increase, which greatly increases the cost of use and maintenance and affects the efficiency of the enterprise.
