Embodiment Construction

[0023] figure 1 It is two views of the cage 01 of the rolling bearing of the present invention. figure 1 Inset a) of is a side sectional view of a section with four pockets of the cage half of the cage 01 . figure 1 Inset b) of is a plan view of a section with four pockets of the cage half of cage 01 .

[0024] figure 1 The half of the cage 01 shown in is used to guide the eight balls that are used as rolling elements in the ball bearing. For this purpose, the cage 01 has eight spherical cage pockets 02 . Holes 03 in the cage 01 for passing rivets or other connecting means (not shown) are provided between the cage pockets 02 . To mount the ball bearing, eight balls are provided between the two halves of the cage, and the two halves of the cage 01 are connected to each other by eight rivets.

[0025] Eight cage pockets 02 are distributed evenly along the annular cage 01 . Thus, the midpoints of the cage pockets 02 are at an angle of 45 degrees to each other. The spherica...

Abstract

The invention relates to a rolling element bearing comprising a cage (01) with cage pockets (02) for guiding rolling elements which are guided in the cage pockets (02) with an axial play at least in the axial direction (04) of the rolling element bearing, thereby defining an axial cage pocket clearance. The invention is characterized in that the cage pocket clearance in a plurality of cage pockets (02) ranges between 0.07 millimeter and 0.17 millimeter.

Description

technical field [0001] The invention relates to a rolling bearing with a cage for guiding rolling elements. Background technique [0002] Rolling bearings can cause a lot of running noise under certain operating conditions, which can cause disturbances in many applications or even prevent the use of rolling bearings. In the case of rolling bearings with a cage made of sheet metal or stiff fabric for guiding the rolling elements, the noise is caused in particular by the excitation of the rolling elements to the cage. [0003] DE 197 81 320 B4 discloses a noise-reducing rolling bearing with a raceway which is designed as an assembled hollow ring. The hollow ring is composed of a first annular portion in contact with the rolling bodies and a second annular portion surrounding the first annular portion. A gap is formed between these annular parts, which gap is filled with oil or another liquid. The raceway of the first ring part deviates from the circular shape in sections by...
