Abstract
The utility model relates to a bearing holder with oil groove, including the holder body, a plurality of bearing windows have been seted up on the holder body, the oil groove has been seted up on bearing window's top face and the bottom face. This needle bearing holder with oil groove has seted up the oil groove through having seted up on the top face and the bottom face at the bearing window, can reduce the contact of bearing end face to the holder when the bearing rotational speed is too high, prevents that the holder high temperature deformation from melting and lead to the needle bearing inefficacy to needle bearing's life has been improved.
Description
Technical Field
The utility model relates to a bearing technical field especially relates to a bearing holder with oil groove.
Background
As shown in fig. 1, a conventional needle bearing cage includes a cage body 1 ' and needle roller windows 2 ' formed along a circumferential direction of the cage body 1 '. However, when the rotation speed of the needle bearing is too high, the top end face and the bottom end face of the needle roller can be in contact friction with the top end face and the bottom end face of the needle roller window, and the needle bearing can be deformed and melted due to high temperature after being used for a long time, so that the needle bearing is failed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a simple structure, lubricated effectual, the long service life's bearing holder that has the oil groove.
The utility model discloses a realize through following technical scheme: a needle roller bearing retainer with oil grooves comprises a retainer body, wherein a plurality of needle roller windows are formed in the retainer body, and the oil grooves are formed in the top end face and the bottom end face of each needle roller window.
Preferably, the oil groove is arc-shaped, the thickness of the oil groove is the same as that of the retainer body, the oil groove on the top end face is sunken upwards, and the oil groove on the bottom end face is sunken downwards.
According to the requirement, in order to store oil conveniently, an outer beam is arranged on the outer end face of the upright column of the retainer body, the height of the outer beam is the same as that of the upright column, and an arc-shaped oil storage tank is arranged on the outer beam along the length direction of the outer beam; in order to facilitate the installation of the roller pins, an inner beam is arranged on the inner end face of the upright post of the retainer body, the height of the inner beam is the same as that of the upright post, and clamping grooves for limiting the roller pins are formed among the end face of the side portion of the inner beam, the end face of the side portion of the roller pin window and the end face of the side portion of the outer beam.
The utility model has the advantages that: this needle bearing holder with oil groove has seted up the oil groove through having seted up on the top face and the bottom face at the bearing window, can reduce the contact of bearing end face to the holder when the bearing rotational speed is too high, prevents that the holder high temperature deformation from melting and lead to the needle bearing inefficacy to needle bearing's life has been improved.
