Embodiment Construction

[0018] exist figure 1 The comb-shaped cage 2 shown in is configured as a double-comb-shaped cage, and basically consists of a cage ring 4 and a certain number of cage rings 2 scattered in the circumferential direction, axially from the cage ring 4 These beams hold and guide the associated rolling elements 8 configured as bearing rollers substantially along the axial generatrices 10 of the rolling elements 8 .

[0019] exist figure 1 In the embodiment shown in , the cage ring 4 consists of two annular disks 12 , 14 arranged coaxially with one another, which are integrally connected to one another by means of a plurality of spacers 16 arranged distributedly in the circumferential direction of the annular disks . as from figure 1 It can be seen that the two annular disks 12, 14 have the same wall thickness a or b and that the axial distance c between the two annular disks 12, 14 is also substantially the same as the wall thickness a or b, so that The spacer 16 also has the sa...

Abstract

The invention relates to a comb-shaped holding frame formed by plastic and a manufacturing method thereof. The comb-shaped holding frame comprises a holding frame ring for beam frames corresponding to attached rolling bodies in number. The beam frames are projected from the holding frame ring and maintain and guide the rolling bodies along a generatrix. In order to realize different strength requirements of the holding frame ring and the beam frames and avoid deformation so as to realize the same wall thickness in all regions of the holding frame ring, the holding frame ring is formed by a plurality of annular disks which are identical in wall thickness and are coaxially arranged, two adjacent annular disks are connected with each other by means of a plurality of separators arranged therebetween, the beam frames are configured to extend axially and have side wing strip-shaped bars matched with the rolling bodies in shape, and the wall thickness of wall elements forming the strip-shaped bars is identical with the thickness of the annular disks as far as possible.

Description

technical field [0001] The invention relates to a comb-shaped cage made of plastic for rolling bearings according to the features of the preamble of claim 1 and a method for producing such a comb-shaped cage according to the preamble of claim 6 Methods. Background technique [0002] The task of the rolling bearing cage is to hold and guide the rolling elements (balls, rollers, needles) distributed in the circumferential direction of the bearing and to prevent them from touching each other. These rolling bearing cages generally have a complex structure, so that their production is complex and expensive, especially in the case of embodiments made of metal, such as brass. Furthermore, rolling bearing cages made of metal have the disadvantage that they undesirably increase the rotating mass of the bearing during operation. Therefore, there are also rolling bearing cages made of plastic. [0003] A common method for producing rolling bearing cages made of plastic is injection ...
