Embodiment 1

[0030] Such as Figure 1-6 The shown bearing cage includes two identical upper and lower annular half cages, which can be connected up and down in the axial direction, and the connection surface of the two annular half cages is the inner end surface 22, and the two half ring The cages are snap-connected through a plurality of connecting points provided on the inner end surface 22 along the circumferential direction of the ring. After the two half-cages are connected, a plurality of pockets 21 are formed between the two half-cages along the circumferential direction. The inner end surfaces 22 are evenly spaced with pocket-shaped grooves 20 , and the inner end surfaces 22 between adjacent pocket-shaped grooves 20 are all provided with locking connection points. The inner end surface 22 protrudes from the inner end surface 22 and is provided with a locking arm 16, and one side of the locking arm 16 is recessed in the inner end surface 22 to be provided with a locking groove 15, a...

Embodiment 2

[0037] A bearing, the bearing includes any one of the above-mentioned bearing cages. This cage can be used on a bearing as a bearing cage.

[0038] When the above-mentioned bearing cage is used for bearing assembly, first put the fitted bearing on the workbench, and then put a single half cage so that the rolling elements are in the pocket of the cage, and then put it into another cage. When placing one and a half cages and another half cage, it is necessary to ensure that the lock arms and lock grooves of the two half cages correspond to each other, and finally put the bearings with the cages in the corresponding press-fitting equipment for press-fitting. So far, the assembly work of the cage is completed.

[0039] This embodiment specifically relates to the bearing cage described in Embodiment 1, which is mainly used in related bearings with large impact, large vibration, poor heat dissipation, and medium-to-high speed operation.

Abstract

The invention relates to the technical field of bearings, in particular to a retainer and a bearing. Domestic bearing retainers are mainly semi-wrapped plastic crown-shaped retainers and stamped steelwave-shaped retainers, the riveted steel retainers are poor in heat dissipation performance and vibration absorption performance, and the plastic crown-shaped retainers are insufficient in impact resistance. In order to solve the problems, the following technical scheme is adopted. The bearing retainer comprises two identical annular half-retainers, wherein the two half-retainers are connected through a plurality of connecting point lock catches arranged on the inner end faces in the annular circumferential direction; pocket-shaped grooves are evenly formed at intervals in the inner end faces, lock catch connecting points are arranged on the inner end face between every two adjacent pocket-shaped grooves, and after the two half-retainers are connected, a plurality of pocket holes are formed between the two half-retainers by splicing the pocket-shaped grooves; and the connecting position of the two annular half-retainers is sunken inwards to form a circumferential oil groove, and the circumferential oil groove communicates with the pocket holes. According to the scheme, the retainer is kept light, meanwhile, the impact resistance is improved, and the heat dissipation capacity is improved.

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 at the same time guide the rolling elements to run in the raceway. At present, half-packed plastic crown-shaped cages and stamped steel wave-shaped cages are mainly used in China to meet the needs of working conditions. For example, the Chinese invention patent with the publication number "CN103322056A" and the name "Bearing Cage" discloses a The bearing cage includes two side retaining rings and pillars. The pillars connect the retaining rings on both sides to form a column structure. The cage is placed between the outer ring and the inner ring of the bearing. The pillars and the side retaining rings are made of steel materials. A freely rotatable bearing rolling body is clamped betwee...
