Problems solved by technology

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.

Embodiment 1

[0031] Such as Figure 1-5 As shown, an anti-bolt heel-toothed gasket 2 includes a gasket body 21, and two end faces 211 of the gasket body are respectively provided with radial tooth shapes along the radial direction; the radial tooth shapes include A plurality of external tooth shapes 212 extending from the position of the outer circular surface 214 of the gasket along the end surface to the inside, and a plurality of internal tooth shapes 213 extending from the position of the inner hole 215 of the gasket along the end surface to the outside. The tooth shapes are alternately arranged at intervals, the interval between two adjacent outer tooth shapes and inner tooth shapes is relatively small, and the outer tooth shapes and inner tooth shapes are arranged densely and in large numbers.

[0032] The outer tooth shape 212 gradually narrows inward from the position of the outer circular surface, and gradually becomes lower in height, and the inner tooth shape 213 gradually narro...

Embodiment 2

[0038] The external tooth shape and the internal tooth shape of the present invention are obtained through a cold stamping process.

Embodiment 3

[0040] Such as Figure 5 As shown, a high-strength bolt connection pair includes a first connected part 3, a second connected part 4, a bolt 1, and a nut 6. The first connected part 3 and the second connected part 4 are connected through the bolt 1 and the nut 6, Between the head of the bolt 1 and the connected part 3, an anti-bolt heel-tooth-shaped washer 2 is provided.

[0041] A nut washer 5 is arranged between the connected part 2 and the nut.

[0042] The nut washer 5 is a flat washer.

[0043] Structure and working principle of the present invention illustrate:

[0044]The present invention is based on the common flat pad, wherein the outer tooth shape and the inner tooth shape are obtained by cold stamping process, and radial tooth shapes interlaced inside and outside are formed on both ends. Due to the difference in diameter between the outer circular surface and the inner hole of the gasket, and the number of teeth of the outer tooth shape and the inner tooth shape...

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...
