The invention discloses a roller bearing retainer for an electric vehicle of a new energy vehicle. The roller bearing retainer comprises a retainer body, wherein a bearing outer ring is arranged outside the retainer body; a bearing inner ring is arranged inside the retainer body; both the bearing outer ring and the bearing inner ring are connected with the retainer body in a matching mode; the retainer body comprises upright posts, a left guide baffle edge and a right guide baffle edge, wherein the upright posts are radially arranged, and ball pocket holes are formed between the upright posts;the left guide baffle edge is arranged on that left sides of the upright posts and is fixedly connected with the upright posts; the right guide baffle edge is arranged on the right sides of the upright posts and is fixedly connected with the upright posts; and the section of the retainer body is in a Z shape, a plurality of rollers are embedded in the retainer body, and the rollers are connectedwith the retainer body in a matching mode. The problems of early failure, poor noise and the like caused by insufficient lubrication and large friction in the use process of an existing bearing are solved.
Description
technical field [0001] The invention relates to the field of bearings, in particular to a roller bearing cage for new energy vehicles and electric vehicles. Background technique [0002] With the increasingly stringent environmental regulations and the increasing consumption of energy, the global demand for environmentally friendly vehicles is increasing, and new energy electric vehicles are accelerating their popularity. The bearings of new energy electric vehicles have been working and running under the conditions of high speed, rapid acceleration and rapid deceleration for a long time. The bearings must meet the requirements of high speed, low torque and low noise. The existing "window hole" nylon cage (such as Figure 4 , Figure 5 As shown), problems such as insufficient lubrication, early failure and poor noise caused by high friction are prone to occur during use. Contents of the invention [0003] The purpose of the present invention is to provide a roller bearing...
