Embodiment 1

[0030] like Figure 1-5As shown, a bearing cage is shown, the cage is an annular cage, which is formed by splicing a plurality of identical cage modules 1 connected by end-to-end clamping, and at least one cage module 1 is distributed along the circumferential direction on the cage module 1. Pocket 2. The holder module 1 is provided with a card slot on one side and a clip 4 on the other side. When connecting, the card slot of one holder module 1 is fitted with the card bar 4 on the other holder module 1, and the connection is made. into a complete ring to form the bearing cage. The clamping groove is a dovetail groove 3 with a gradually narrowed opening, and the clamping strip 4 is a clamping strip 4 that matches the shape of the dovetail groove 3, and the clamping groove and the clamping strip 4 are clamped from the axial direction of the bearing. It is fixed and limited by the narrow end of the dovetail groove 3 to form a circumferential anti-dropping structure. The inner...

Abstract

The invention relates to the technical field of bearings, in particular to a bearing cage and a roller bearing having the same. Domestic large-size roller bearings mainly use integrally processed copper cages, which have problems such as expensive casting materials, difficult processing, and complicated installation. In order to solve the above problems, the present invention adopts the following technical solutions: a bearing cage, which is formed by clamping a plurality of identical cage modules, and is connected into a complete ring to form the bearing cage; the cage The module includes an outer support beam arranged on the radial outer side, and an inner support beam arranged on the radial inner side. A weight-reducing groove opened on one side; at least one pocket is distributed along the circumferential direction on the cage module. In the technical solution of the present invention, the bearing cage is assembled in a modular manner to provide a large-size bearing cage that is light and cost-saving.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a cage and a bearing. Background technique [0002] The cage is one of the main parts of the bearing, which is used to separate the rolling elements so that they are in the correct position and guide the rolling elements to run in the raceway. At present, domestic large-size bearings mainly use integrally processed copper cages, which are not only difficult to process and difficult to ensure accuracy, but also large in size and high in cost. [0003] For example, the invention patent with the publication number of "CN107243649A" and the title of "a large-size thrust angular contact ball bearing cage finishing process" discloses the well-known features of the large-size bearing cage. Its specification describes: the well-known large-size (product outer diameter ≥ 800mm) thrust thrust angular contact ball bearing. The bearing cage is made of high-strength cast brass material, wi...
