Description

Rolling bearings for cylindrical rolling elements

The innovation relates to a roller bearing, consisting of at least one race with lateral ribs and a cylindrical WaIZk ^ ₄ rolling in this. Ren, which are set off at their ends to a smaller diameter and are gripped under in this area by the retaining rings arranged on the race ring.

Rolling bearings in full complement design are already known, which are guided on the end face of the raceway ribs are. However, these rolling bearings lack funds for holding the rolling elements, which makes handling Such rolling bearings are difficult in many cases.

In other known rolling bearings, the rolling bodies are arranged in a cage. This is true for a Perfect guidance and retention of the rolling elements ensured, the number of rolling elements is compared to full complement Rolling bearings, however, are lower and, as a result, their load-bearing capacity.

Finally, roller bearings in full complement design are known in which dit. Ends of the rolling elements are reduced to a smaller diameter. This measure results in the possibility of a A satisfactory rolling bearing holder, however, the lack of guidance has a disruptive effect on these rolling bearings the end.

The innovation is based on the task of creating a rolling bearing for cylindrical rolling elements that is full complement is executed and is characterized by a high load-bearing capacity and in which the bracket in a simple manner and guidance of the rolling elements is accomplished.

According to the innovation, this is achieved in that the rolling elements are guided on the end face of the raceway ribs. By this measure is achieved that with a full ^ of loose bearings not only a secure mounting ^ - but also a perfect guidance of the rolling elements is guaranteed.

In a further embodiment of the innovation, it is proposed that the retaining rings be split at one point on their circumference, provided with a circumferential axially directed collar rings are formed, which in a groove of the Engage the raceway rims.

This design ensures that the retaining rings can be mounted without difficulty even in multi-row rolling bearings and are still anchored in the axial direction g positionally, whereby a simple and secure mounting of the rolling elements is achieved.

Another development of the innovation provides that the retaining rings with individual, distributed over the .Umfang Sections engage in a groove of the raceway rims and the intermediate sections for supply and removal of lubricating oil have recesses.

Due to the proposed arrangement of the recesses, perfect lubrication is possible with one as well as possible with multi-row rolling bearings.

In the drawing is an embodiment of the innovation according to the invention Rolling bearing shown.

Show it:

Figure 1 shows a rolling bearing in section along the line I-I of Figure 2 and

Figure 2 shows a retaining ring in view.

The multi-row rolling bearing shown consists of the outer race 1, the inner race 2 and the between these rolling elements 3 which are held in the outer race 1 by retaining rings 4 and 4 a. The rolling elements 3 are set down at their ends 5 to a smaller diameter and are 6 with their end faces the ribs 7 of the outer race 1 out.

The rims 7 have a groove 8 which is used to axially fix the retaining rings 4 and 4 a. For this purpose, a slot having 9 having Halterin.se 4 or 4 a distributed over the circumference portions 10, which are provided with (a nose. 11 The intermediate sections 12 are flattened in the shown embodiment, so that lubricating oil supplied and unhindered can be discharged.

To hold the rolling elements 3, the retaining rings 4 are provided on their inner circumference with a circumferential, axially directed collar 13, which engages under the ends 5 of the rolling elements 3, which are offset to a smaller diameter. Appropriately , in the embodiment shown, the design is such that the retaining rings 4 a lying between two rows of rolling bodies are provided with an axially directed collar 13 on both sides.
