Problems solved by technology

[0002] Most of the wedging surfaces between the existing combined anti-loosening washers are ordinary inclined surfaces, and the wedging design of the ordinary inclined surfaces cannot exert the anti-loosening effect well. After calculation, the effective area of ​​the anti-loosening washers designed with this ordinary inclined surface It only accounts for about 50% of the total inclined surface area, and the failure phenomenon of "not loosening" of the anti-loosening gasket often occurs

Embodiment Construction

[0032] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0033] In this disclosure, in the absence of a contrary statement, the used orientation words such as "up, down, bottom, top" can refer to figure 1 The direction of the drawing, the specific use of the anti-loosening washer of the present disclosure is not limited by the "upper, lower, bottom, top" described in the present disclosure. The distance in this disclosure refers to the length of the shortest line between two components. In the present disclosure, the thread lead angle is the included angle between the tangent of the helix (wire) of the threaded connector (helix surface) on the medium-diameter cylinder and the plane perpendicular to the axis.

Abstract

The disclosure relates to an anti-loosening washer for a threaded connection and a preparation method thereof. The anti-loosening washer includes an upper washer and a lower washer, and the bottom of the upper washer is provided with a plurality of first ratchets distributed in a fan shape. The top of the lower washer is provided with a plurality of second ratchets that are wedged with the first ratchets, and the first ratchets have a wide surface that fits with the second ratchets and an area smaller than the second ratchet. The narrow surface of the wide surface, the wide surface is a helical surface formed by the helical movement of the generatrices spaced apart from the central axis of the washer above the axis, and the helix angle of the wire at the middle diameter of the helical surface is greater than that of the threaded connection The helix angle of the piece, the middle diameter of the helical surface is the position equidistant from the inner and outer circumferences of the first ratchet on the helical surface. The anti-loosening washer provided by the disclosure has good anti-loosening effect.

Description

technical field [0001] The present disclosure relates to a lock washer for a threaded connection and a preparation method thereof. Background technique [0002] Most of the wedging surfaces between the existing combined anti-loosening washers are ordinary inclined surfaces, and the wedging design of the ordinary inclined surfaces cannot exert the anti-loosening effect well. After calculation, the effective area of ​​the anti-loosening washers designed with this ordinary inclined surface It only accounts for about 50% of the total slope area, and the failure phenomenon of "not loosening" of the lock washer often occurs. Contents of the invention [0003] The purpose of the present disclosure is to provide an anti-loosening washer for a threaded connection and a preparation method thereof. The anti-loosening washer provided by the present disclosure has a better anti-loosening effect. [0004] In order to achieve the above object, the present disclosure provides an anti-loo...
