SU1444567A1 - Composite washer for threaded connection of parts - Google Patents

Abstract

The invention relates to mechanical engineering and can be used in threaded connections of machine parts that require large tightening forces, subject to periodic disassembly and subsequent assembly during operation. The purpose of the invention is to improve the condition of disassembling the joint by reducing the disassembling force. Their radius of curvature corresponds to the corresponding radius of curvature K4 and 5. K4 and 5 are made with side sections. When the casing 6 is rotated by 90 around the axis K4 and 5, under the action of a gentle load, it radially diverges. A gap is formed between the surfaces of the washer and nut 2. The installation between the K4, 5 and the clip 6 rolling elements reduces the disassembly force, 1 3.p. f-ly at 8 Il. (f, C

Description

bakes free removal of clip 6 and rings 4 and 5.

The efficiency of the washer is ensured only if the following disassembly of the joint is observed by reducing | g 2 a gap S is formed, which is subject to disassembly effort.

Fig, 1 shows a composite washer in the working position, a general view of the fig, 2 - the same, top view; on figoZ - the same, when disassembling, the general condition of the situation: the distance between the equilibrium | figure 4 - view A in FIG. 3 | Fig. 5 shows an embodiment of a washer with rolling elements; FIG. 6 is a section BB in FIG. 5; 7 - locking element - ferrule in FIG. 8 - 20 rings

A nut 2j is screwed onto the threaded rod t between it and the bearing; The top of the part 3 is fitted with a composite washer, which contains two 25 rings 4 and 5, enclosed by the sleeve 6. In the holder 6, holes 7 are made for the tool, two diametrically located protrusions 8 and 9 located at the minimum distance a from each other, and . two recesses 10 and 11, with the radius of curvature of the protrusions corresponding to the radius of curvature of the rings. In the case of rolling elements 12-15, the grooves 16 are made on the outer curved surface of the rings 4 and 5 and the projections 8 and 9, in which the rolling elements move. The rings have lateral parallel sections 17 and 18, which form its width b, transverse to; slots 19 and sloping surfaces 20,

Composite washer works as follows.

When the nut 2 is tightened to the set limit, the tightening force is transmitted through the rings 4 and 5 combined with the inclined surfaces to the part 3. At the same time, tension between the rings 4 and 5 and the holder 6 occurs, which prevents the latter from displacing.

When disassembling, a tool (not shown) and turning 40 are inserted into hole 7.

by the projection points of the protrusions “the holder 6 must be greater than the width b of the rings. The design of the washer reduces the disassembly force. The presence of grooves on the rings and cage, coupled with rolling elements, increases the reliability of fixation of the joint when operating under vibration loads.
