Abstract
The utility model provides a new energy automobile motor bearing holder, its bottom is provided with annular supporting seat, evenly laid a plurality of connecting seats on the annular supporting seat, be provided with the ball pocket hole between the connecting seat, the ring body external diameter that the connecting seat formed is less than the external diameter of annular supporting seat, the oil groove has been seted up on the connecting seat surface, and the oil groove bottom is opened completely. Compared with the prior art, the annular supporting seat is arranged and protrudes outwards, so that the overall tensile strength of the retainer is enhanced, meanwhile, the oil groove is formed in the connecting seat on the retainer, lubricating grease in the bearing can flow circularly, the lubricating performance of the bearing is improved, the retainer is prevented from deforming under the conditions of high temperature and high speed, and the heating phenomenon of the bearing is reduced.
Description
Technical Field
The utility model relates to the technical field of bearing retainers, in particular to a new energy automobile motor bearing retainer.
Background
With the development of new energy automobiles, the new energy automobiles have higher requirements on high-temperature and high-speed application working conditions of the bearing of the driving motor, the retainer made of nylon and other materials in the prior art has poor comprehensive performance, and the retainer is easy to deform in structure when applied in a high-speed environment.
For example, in chinese patent publication No. CN 202326737U, entitled "nylon retainer", which has a main body with a steel ball mounting groove, and an outer chamfer and an inner chamfer are machined on one side near a seal ring, such retainer reduces friction force and reduces noise during operation, but the retainer deforms at high temperature and high speed due to small internal space of the bearing and poor fluidity of grease, and the bearing heats and cannot reach the rotating speed.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a new energy automobile motor bearing retainer aiming at the defects of the prior art.
In order to solve the technical problems, the utility model adopts the following technical scheme:
the utility model provides a new energy automobile motor bearing holder, its bottom is provided with annular supporting seat, evenly laid a plurality of connecting seats on the annular supporting seat, be provided with the ball pocket hole between the connecting seat, the ring body external diameter that the connecting seat formed is less than the external diameter of annular supporting seat, the oil groove has been seted up on the connecting seat surface, and the oil groove bottom is opened completely.
Further, a step is arranged between the outer ring of the connecting seat and the annular supporting seat, and the root of the step is in transition through an arc angle.
Further, the oil groove is a trapezoid groove.
Further, the upper end of the connecting seat is provided with a weight reducing groove.
Compared with the prior art, the annular supporting seat is arranged and protrudes outwards, so that the overall tensile strength of the retainer is enhanced, meanwhile, the oil groove is formed in the connecting seat on the retainer, lubricating grease in the bearing can flow circularly, the lubricating performance of the bearing is improved, deformation of the retainer under the conditions of high temperature and high speed is avoided, and the heating phenomenon of the bearing is reduced.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
wherein, 1, annular supporting seat, 2, connecting seat, 3, ball pocket hole, 4, circular arc angle, 5, oil groove, 6, subtract heavy groove.
Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below.
As shown in fig. 1, a new energy automobile motor bearing retainer, its bottom is annular supporting seat 1, be provided with a plurality of connecting seats 2 on the annular supporting seat 1, connecting seat 2 evenly lays, be provided with ball pocket 3 between the connecting seat 2, ball pocket 3 is arranged in holding the rolling element in the bearing.
The annular supporting seat 1 adopts a widening design, compared with the previous retainer, the outer diameter of the annular supporting seat 1 is increased by 0.5-1 mm so as to improve the overall tensile strength of the retainer main body, the outer diameter of an annular body formed by the connecting seat 2 is smaller than the outer diameter of the annular supporting seat 1, a step is formed between the outer ring of the connecting seat 2 and the annular supporting seat 1, the root of the step is transited through an arc angle 4, and the weight of the retainer is reduced on the basis of ensuring the overall rigidity of the retainer through the design, so that the centrifugal force born by the retainer during high-speed operation is reduced.
The connecting seat 2 surface is provided with oil groove 5, and the oil groove 5 bottom is opened, lightens the holder weight through setting up oil groove 5 for the center of mass of holder is closer to steel ball center of rotation, simultaneously, sets up oil groove 5 and still can make lubricating grease fully flow in the bearing, in this embodiment, oil groove 5 is located the cyclic annular body outer lane side that the connecting seat formed, and oil groove 5 is the dovetail groove, the long limit of dovetail groove is down, and run through annular supporting seat, increase the flux of lubricating grease, but the lubricating grease circulated flow in the bearing when the holder works, make the holder can in time supply lubricating grease, and obtain effective lubrication, avoid appearing lubrication failure, the phenomenon of generating heat, the stability of holder shape.
The upper end of the connecting seat 2 is also provided with a weight reducing groove 6, the weight of the whole retainer is reduced by using the weight reducing groove 6, and the centrifugal force during rotation of the retainer is reduced.
The utility model is not limited to the embodiments described, but a person skilled in the art may make modifications or changes without departing from the spirit of the utility model, i.e. the scope of the disclosure, and the scope of the utility model is defined by the claims.
