[0002] The existing bearing needle roller cage is generally a one-piece metal structure. During assembly, the cage needs to be placed on the inner ring first, and then the needle rollers are pressed into the needle roller grooves on the cage. Pressing in one by one, the axis of the cage will gradually deviate from the axis of the inner ring, and the rest of the cage will be close to the inner ring, making it difficult or not in place for the last few needle rollers to be pressed in, and it needs to be adjusted many times before Completed, it took a long time and needs to be improved

Embodiment Construction
[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0015] This preferred embodiment is figure 1 and 3 Shown is a bearing needle roller cage. The cage body 1 is composed of two connecting rings and a plurality of spacer strips arranged between the two connecting rings for isolating adjacent needle rollers 2. The cage body 1 is A disconnection part 12 is provided in the axial direction for opening the cage body 1, and one side of the disconnection part 12 is provided with a buckle 13 bayonet-connected with the other side. Wherein, the diameter of the head of the buckle 13 is larger than the diameter of the bayonet socket, and is pressed through during assembly.
[0016] In this embodiment, the disconnection point 12 is arranged on the connecting ring, and may also be arranged on the connecting ring and the spacer bar at the same time. Cage body 1 consists of figure 2 The shown metal frame 1...

The invention discloses a needle roller cage for a bearing. The cage body is composed of a plurality of spacer strips for isolating adjacent needle rollers and two connecting rings for respectively connecting the two ends of each spacer strip. The cage body There is a disconnection point for opening the cage body in the upper axial direction. One side of the disconnection point is provided with a buckle connected to the other side of the bayonet. The diameter of the head of the buckle is larger than the diameter of the bayonet; the advantage is that through The disconnection part is set on the cage body, after the needle roller is quickly assembled, the cage body is opened from the disconnection part and then put into the inner ring, and then connected to the other side through the protrusion on one side of the crack, which is convenient for assembly and takes less time. ; Preferably, the cage body is composed of an openable metal frame and a shape layer wrapped outside the metal frame. The shape layer is preferably made of PEEK. The deformation and recovery performance of PEEK are relatively good. The cage body is easy to open and has no shape after recovery There will be changes.
Description
technical field [0001] The invention relates to an automobile bearing, in particular to a bearing needle roller cage. Background technique [0002] The existing needle roller cage of the existing bearing is generally a one-piece metal structure. During assembly, the cage needs to be placed on the inner ring first, and then the needle rollers are pressed into the needle roller grooves on the cage. Pressing in one by one, the axis of the cage will gradually deviate from the axis of the inner ring, and the rest of the cage will be close to the inner ring, making it difficult or not in place for the last few needle rollers to be pressed in, and it needs to be adjusted many times before It took a long time to complete and needs to be improved urgently. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a bearing needle roller cage which is easy to install and takes a short time to install on the inner ring of the bearin...
