Abstract

Disclosed is a composite retaining ring for a shaft. The retaining ring is characterized in that a baffle ring sectioned into halves by a circle center is inserted into a groove on the shaft to form a circular baffle ring, the retaining ring is needed to be installed in the groove, a tension ring is sleeved on the external diameter of the baffle ring, and a locking spring is jammed on the external diameter of the baffle ring on the lateral side of the tension ring, thereby forming the composite retaining ring for the shaft.

Description

The compound back-up ring of axle

Affiliated technical field:

The utility model relates to the compound back-up ring of axle that can bear powerful axial impact force and powerful radial impact power in a kind of machinery.

Background technique:

At present, in the production of machinery, the structure that the shaft block ring that uses adopts is by circlip of making than thin material and the back-up ring made with worm structure, circlip in use can not bear axial impact force, the back-up ring of worm structure is when bearing axial impact force, screw thread easily gets loose, and is difficult to guarantee to carry out long-term effectively work.

Summary of the invention:

Can not bear axial force in order to overcome circlip, threaded collar (screw thread easily gets loose) is difficult to work long-term effectively.The utility model provides a kind of to use compound back-up ring, and this compound back-up ring can not only guarantee to carry out long-term effectively work, and can bear powerful axial impact force and radial centrifugal force.

The technological scheme that its technical problem that solves the utility model adopts is: need the position of assembling back-up ring to process suitable groove on axle, a baffle ring that half-and-half dissects through the center of circle inserts in the groove of axle, be combined into the baffle ring of whole circle, external diameter at baffle ring puts cranse, blocks jump ring on the shelves ring of the side of cranse.Form the whole compound ring washer of axle.Baffle ring bears axial impact force during work; cranse protection shelves ring does not break away from the groove of rotating shaft when the rotating shaft high-speed motion, jump ring prevents that cranse from coming off; thereby guarantee that compound ring washer can bear powerful axial impact force and radial centrifugal force, and permanently effective reliable work purpose.

The beneficial effects of the utility model are, make axle can bear powerful axial impact force and radial centrifugal force with compound back-up ring when working, and simple in structure, and are easy to make and can work effectively reliably and with long-term.

Description of drawings:

Below in conjunction with drawings and Examples model utility is further specified:

Fig. 1 is a structure sectional view of the present utility model:

Among Fig. 1: 1. shelves encircle, 2. cranse, 3. jump ring, the 4. groove of rotating shaft.

Embodiment:

In Fig. 1, the shelves ring that half-and-half dissects through the center of circle 1., 1. the groove that inserts rotating shaft is combined into round shelves ring in 4., 2. cranse is placed in a shelves ring external diameter 1., 3. jump ring is stuck in cranse side 2., shelves ring outer radius is 1. formed compound ring washer.

Claims

A kind of compound back-up ring of usefulness is characterized in that: on the baffle ring external diameter that is half-and-half dissectd through the center of circle, be with a cranse, the baffle ring card of cranse side has jump ring.
