JPH02195019A - Metal plate holder of ball bearing - Google Patents

Abstract

PURPOSE: To prevent the damaging of a rivet and a connection projecting piece by providing portions shifted in the axial direction and engaged with each other within the range of the connection projecting piece in a metal plate retainer for a bell bearing. CONSTITUTION: To make fitting connection between semicircular bodies 1 and 2 in a surface perpendicular to a rivet axis or a bearing axis, portions 5' and 6' shifted in an axial direction and engaged with each other are provided in the semicircular bodies within the range of connection projecting pieces 5 and 6. Forces applied on this surface area all transmitted not by a rivet 7 but the portions 5' and 6' engaged with each other. The recesses or protruded portions thereof additionally reinforce the connection projecting pieces 5 and 6. Thus, the strength and stability of the holder are increased.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a metal plate holder for ball bearings according to the generic concept of claim 1.

[Conventional technology]

A cage of the above-mentioned type is disclosed in German Patent No. 9252
This can be seen from the specification of No. 03. In the retainer described here, two half-rings, of which the pocket halves are integrally formed, are fastened to one another by means of studs in the area of a connecting tab arranged between them. This rivet connection has proven to be unsatisfactory in many practical applications. These retainer halves are often subjected to such great loads that the studs or connecting tabs break in the area of the stud holes.

[Problem to be solved by the invention]

The section of the invention does not have these disadvantages and, in particular in the area of the connecting tabs, is designed such that neither the studs nor the connecting tabs are damaged.
It is to show the metal plate holder constructed.

[Means to solve the problem]

This object is achieved in that the area of the connecting tab is provided with axially offset and mutually engaging parts. Special features are described in claims 2 and 3.

The two half-rings have axially offset and mutually engaging parts in the area of the connecting lug, so that the normal riveted connection takes place at this point in a plane perpendicular to the riveted axis. When the two hemicycles are connected directly to each other, the interlocking bonding of both hemicycles occurs directly with each other. Thereby, the shear forces occurring in this plane are transmitted directly from one half-ring to the other without additional loading of studs. These studs are only subjected to tensile forces. The centering of the two halves takes place via the axially offset parts. Furthermore, it is of great significance that the axially offset section significantly strengthens the cage in the area of the connecting tab and thereby increases its stability. These cages are also suitable for applications where rolling bearings are subject to vibration.

The axially offset part does not result in any additional outlays in manufacturing technology and assembly if it consists of a recess or a projection that is simultaneously formed in one piece and plastically deformed during the manufacture of the cage halves.

In order that in cages with an even number of pockets only one tool is required for the manufacture of these cages, according to another preferred embodiment, the axially offset portions are Alternately different directions and alternately different widths.

Thereby, one of the same cage halves only has to be twisted relative to the other and offset from each other by one pocket unit, so that both cage halves fit complementary to each other and are riveted to each other. obtain.

〔Example〕

The present invention will be explained in detail with reference to the drawings.

According to the drawing, the cage consists of two half-rings 1 and 2. Each of these half-rings has pocket halves 3 and 4 adapted to the number of balls 8, respectively. These pocket halves 3 and 4 are connected to each other by connecting tabs 5 and 6, respectively. These connecting protrusions 5 and 6
has holes, in which studs 7 are arranged, which fix the half rings 1 and 2 to each other.

A half-ring l in a plane perpendicular to the rivet axis or bearing axis
and 2, these half rings have axially offset and mutually engaging portions 5' and 6' in the area of the connecting lugs 5 and 6. ing.

Thereby all the forces acting in this plane are
The transmission is not by the studs 7, but by the mutually engaging parts 5' and 6'. These studs 7 are not additionally loaded in such loading conditions; their mutually engaging parts 5' and 6' consist of plastically deformed recesses or projections, and these recesses or The protrusion can simply be integrally formed at the same time as the cage halves are manufactured.

It is clear that these recesses or projections additionally strengthen the connecting tabs 5 and 6. This is because instead of a flat section, a grooved section results.
