Problems solved by technology

[0007] This teaching of the prior art with regard to the adjustment of the elasticity and holding force of the fastening washer cannot therefore be transferred to a lock nut of the formed type, since the plastic washer differs from the washer made of metal in terms of its elastic properties, And because the axial displacement of the inner thread of the washer and the nut body is not provided in the prior art

Embodiment Construction

[0030] as attached Figure 1 to Figure 4As shown, the union nut 10 according to the invention has, on one end side, a nut body 12 with a concentric neck-shaped projection 14 . The union nut 10 is designed, for example, as a hex nut made of steel and in its image 3 and Figure 4 The finished state shown has an internal thread 16 , which is referred to below as “nut thread” 16 . The inner edge 18 of the neck-shaped projection 14 is displaced outward relative to the inner diameter of the thread of the union nut 10 in order to form a socket 20 for a fastening washer 22 . The fastening washer, hereinafter also referred to simply as washer, is made of metal, preferably of elastic material, such as spring steel or spring strip steel. exist Figure 1 to Figure 4 In the embodiment shown, the washer 22 has three segment-shaped recesses, wherein the washer is fastened in the union nut 10 in its circumferential region remaining between these recesses, as formed by prior art Basicall...

Abstract

The invention relates to a lock nut with a nut body and a metal fastening washer, the nut body having a threaded section with an internal thread and connecting to the threaded section the inner annular groove on the The fastening washer is held in the annular groove. Internal threads corresponding to the internal threads of the nut are processed on the inner circumference of the washer, and the internal threads of the washer are axially shifted by a distance relative to the internal threads of the nut, which distance is less than the The pitch of the internal thread. According to the invention, the thickness of the washer on its inner diameter is greater than the thickness of the washer on its outer diameter. The elasticity of the fastening washer and the holding force of the union nut can thus be adjusted.

Description

technical field [0001] The invention relates to a lock nut with a nut body and a washer made of metal, said nut body having a threaded section with an internal thread and a threaded section connected to the threaded section. An inner annular groove, the gasket is held in the annular groove, wherein an inner thread corresponding to the inner thread of the threaded section is processed on the inner circumference of the gasket, and the inner thread of the gasket is opposite to the inner thread of the The internal thread of the nut body is axially displaced by a distance which is smaller than the pitch of the internal thread. Such lock nuts are known, for example, from DE2638560C, DE4313809C1 and DE4313845C1. [0002] Other similar cage nuts are described in US2,318,397A, US2,410,090A, GB2287764A and GB610355A. Background technique [0003] In particular, the invention relates to a lock nut having a metal body with an internal thread and a neck-like protrusion connected to the...
