Description

Technical Field

[0001] The utility model belongs to the technical field of bearing assembly assembly, in particular to an outer spacer ring of a bearing assembly which is convenient for disassembling a spring ring. Background Art

[0002] The important function of the outer spacer of the bearing assembly is to install the oil storage ring inside to provide lubricating oil atmosphere and ensure the lubrication requirements throughout the design life. There are grooves at both ends of the outer spacer to install the spring ring. The function of the spring ring is to fix the oil storage ring, and the surface is blackened and the end is cut flat to facilitate prying out with a thin iron needle.

[0003] Disadvantages of existing designs:

[0004] 1. When using a thin iron needle to pry the spring coil, the spring coil is easy to break and fly;

[0005] 2. When taking out the spring coil again, the friction between the spring coil, groove and oil storage ring will cause the oxide layer on the surface of the part to fall off, forming small debris and causing pollution;

[0006] 3. Thin iron needles can easily leave scratches on the surface of the oil storage ring, affecting the appearance;

[0007] 4. The removal process is time-consuming and laborious.

[0008] Because in application, the spring ring cannot block the flow of lubricating oil, and considering the cost, it is inconvenient to change the existing shape. Utility Model Content

[0009] In order to solve the above problems, the utility model provides an outer spacer ring of a bearing assembly which is convenient for disassembling a spring ring, so that the spring ring can be taken out quickly.

[0010] The utility model is realized by the following technical solutions:

[0011] The invention discloses an outer spacer ring of a bearing assembly for facilitating the removal of a spring ring. Grooves are arranged along the circumference of the inner cavity of the outer spacer ring at both ends. The spring ring for fixing an oil storage ring is accommodated in the groove. Through holes for facilitating the insertion of a thin iron needle are symmetrically arranged on the outer wall of the outer spacer ring corresponding to the spring ring.

[0012] Furthermore, the diameter of the through hole is larger than the diameter of the thin iron needle, and the diameter of the through hole is not larger than the diameter of the spring coil.

[0013] Furthermore, the spring ring is in an annular opening structure, and the spring ring opening is located at a portion of the groove where there is no through hole.

[0014] Furthermore, the opening end of the spring ring is a flattened oblique section.

[0015] Furthermore, the outer spacer is cylindrical.

[0016] The beneficial effects of the utility model are:

[0017] 1. The utility model only has through holes symmetrically opened at the inner groove of the outer spacer ring. When disassembling, a thin iron needle is inserted into the through hole, and the spring coil is pushed out and then clamped out with tweezers. The structure is simple and the cost is low.

[0018] 2. The utility model is easy to clean, simple to operate, highly reliable, and has no performance impact on existing bearing components. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the present utility model.

[0024] Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0026] As shown in the figure, an outer spacer of a bearing assembly that is easy to remove a spring ring, the outer spacer 1 is cylindrical, and grooves 2 are respectively arranged along the circumference at both ends of the inner cavity of the outer spacer 1, and the inner cavity of the groove 2 accommodates a spring ring 3 for fixing an oil storage ring, and the oil storage ring is located between the two spring rings 3. Through holes 4 are symmetrically arranged on the outer wall of the outer spacer 1 corresponding to the spring rings 3. The diameter of the through hole 4 is larger than the diameter of the thin iron needle 5, which is convenient for the thin iron needle to be inserted, and the diameter of the through hole 4 is not larger than the diameter of the spring ring 3, so as to prevent the spring ring 3 from being squeezed out of the through hole 4.

[0027] Furthermore, the spring ring 3 is in an annular opening structure, which is convenient for the spring ring 3 to be installed in the groove 2. When assembling, the opening of the spring ring 3 is placed at a place where there is no through hole in the groove, which is convenient for the thin iron needle 5 to be inserted into the through hole 4 to push out the spring ring 3. After the spring ring is pushed out, it can be clamped out with tweezers. The structure is simple, the cost is low, and it is easy to clean, easy to operate, and has high reliability, and has no performance impact on the existing bearing assembly.

[0028] Furthermore, the open end of the spring coil 3 may be a flattened oblique section or a flat surface.

[0029] The basic principles, main features and advantages of the utility model are shown and described above. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model.
