Abstract

The utility model provides a bearing retainer ring for a rolling bearing, belonging to the technical field of bearing inhibiting devices. The bearing retainer ring comprises a retaining loop (3) and a retaining ring (4), wherein the retaining loop (3) has a two-section structure; the external round of the retaining loop (3) is provided with a first sidestep (3-1); the retaining ring (4) has a whole structure; the internal round of the retaining ring (4) is provided with a second sidestep (4-1); and the first sidestep (3-1) and the second sidestep (4-1) are matched with each other. The bearing retainer ring has the benefits that the retaining loop and the retaining ring can bear greater axial force, the positioning of the bearing retainer ring is safer and more reliable, and the bearing retainer ring is convenient to disassemble and assemble.

Description

A kind of end ring that is used for rolling bearing

Technical field

The utility model relates to bearing limit stoper technical field, is specifically related to a kind of end ring that is used for rolling bearing.

Background technique

What generally rolling bearing is carried out that axial limiting uses is circlip for shaft, and specification limit is between diameter of axle d=3～200mm, and circlip for shaft is convenient to loading and unloading by the elasticity of itself.But when stirring apparatus for reaction kettle mechanical seal designs, usually can run into the bearing of the diameter of axle greater than 200mm, larger axis footpath rolling bearing just need be designed end ring safe and reliable, that be convenient to load and unload it is carried out axial limiting.

The model utility content

For the circlip for shaft specification limit that solves existing standard covers infull problem, the utility model provides a kind of end ring that is used for rolling bearing, and it is applicable to the axial limiting of larger axis footpath rolling bearing.

The technological scheme that the utility model technical solution problem is adopted is as follows:

A kind of end ring that is used for rolling bearing comprises baffle ring and back-up ring, and baffle ring is two valve structures, and the cylindrical of baffle ring is provided with first step; Back-up ring is an overall structure, and the interior circle of back-up ring is provided with second step, and described first step matches with second step.

The beneficial effects of the utility model are: baffle ring and back-up ring can bear bigger axial force, locate more safe and reliable, and be convenient to loading and unloading; This end ring is applicable to the axial limiting of larger axis footpath rolling bearing.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further details.

To shown in Figure 5, the end ring that is used for rolling bearing of the present utility model comprises as Fig. 1: baffle ring 3 and back-up ring 4, and baffle ring 3 is two valve structures, and the cylindrical of baffle ring 3 is provided with first step 3-1, and this first step 3-1 carries out axial limiting to back-up ring 4; Back-up ring 4 is overall structures, and the interior circle of back-up ring 4 is provided with second step 4-1, and described first step 3-1 matches with second step 4-1.

The assembly process of end ring of the present utility model when using is: lower lip envelope 7 is installed, and bearing 5 is packed in the axle sleeve 1, and the inner ring of bottom end bearing leans against on the shoulder of axle sleeve 1; The baffle ring 3 of distinguish is contained in the restraining groove of axle sleeve 1, reinstalls whole back-up ring 4, the baffle ring 3 of distinguish is fixing, and rivet tightly towards nest in the cooperation place of baffle ring 3 and back-up ring 4, or assort the seam screw and rivet tightly; With upper lip envelope 2 bearing housing 6 of packing into, bearing housing 6 is installed again it is cooperated with bearing outer ring.

End ring of the present utility model has solved the assembly problem of resilient bearing back-up ring, and the thickness of baffle ring 3 and back-up ring 4 can design according to actual needs, makes it can bear bigger axial force, locate more safe and reliable, and be convenient to loading and unloading.Therefore, end ring of the present utility model is applicable to the axial limiting of larger axis footpath rolling bearing.

Claims

1. an end ring that is used for rolling bearing is characterized in that, this end ring comprises baffle ring (3) and back-up ring (4), and baffle ring (3) is two valve structures, and the cylindrical of baffle ring (3) is provided with first step (3-1); Back-up ring (4) is an overall structure, and the interior circle of back-up ring (4) is provided with second step (4-1), and described first step (3-1) matches with second step (4-1).
