Shaft sleeve with tricyclic oil groove

The utility model discloses a shaft sleeve with a tricyclic oil groove and solves the technical problems that the bearing capacity of the inner wall of a traditional shaft sleeve is low and the service life of the shaft sleeve is short. The shaft sleeve with the tricyclic oil groove comprises a cylinder shaft sleeve body and the oil groove, wherein the oil groove is arranged on the inner wall face of the shaft sleeve body. The shaft sleeve with the tricyclic oil groove has the key that the oil groove is of a tricyclic structure on the inner wall face of the shaft sleeve body. Compared with the prior art, the oil reserve and the oil distribution effect of the shaft sleeve with the tricyclic oil groove are equivalent to that of a shaft sleeve with four X-shaped oil grooves evenly arranged crosswise, whereas compared with the shaft sleeve with four X-shaped oil grooves evenly arranged crosswise, the bearing area of the inner wall of the shaft sleeve is effectively increased, and the service life of the shaft sleeve is prolonged.
