Description
Technical Field
The invention relates to the field of automobile transmission shafts, in particular to a self-lubricating cylindrical three-ball pin of a spherical ring roller.
Background
The conventional column type tripod universal joint has the functions of transmitting torque and motion and is a joint part of an automobile transmission shaft; the ball ring or bearing with rolling needle can slide in three tracks in the bell housing to realize the length change of the driving shaft during the motion of the automobile, and has high requirement on the performance of tripod universal joint.
The roller pin is used between the tripod journal and the ball ring of the existing cylindrical tripod universal joint, and in order to ensure that the pin does not fall off or clamp during assembly and operation of the tripod, a proper amount of lubricating grease needs to be coated between the ball ring and the roller pin, so that the performance requirement is high. And the rolling needle is fragile under the high intensity operational environment, also can lead to the tripod universal joint function to reduce or fail. In order to ensure that the needle does not fall off, the root of the shaft neck of the tripod is provided with a bevel for bearing the needle roller and a fillet for preventing interference. Meanwhile, a needle roller check ring is assembled at the top end of the three-pin-frame shaft neck. Due to the reasons, the three-ball pin universal joint has high machining precision requirement, high manufacturing difficulty and high manufacturing cost.
Disclosure of Invention
The invention aims to overcome the defects in the prior art, and provides the self-lubricating cylindrical tripod for the ball ring roller, which not only reduces the manufacturing difficulty and the manufacturing cost, but also prolongs the service life of the tripod universal joint.
The purpose of the invention is achieved by the following technical scheme: the self-lubricating cylindrical tripod ball of the spherical ring roller mainly comprises tripod stands and spherical rings sleeved on each tripod stand of the tripod stands, wherein the inner walls of the spherical rings are uniformly provided with a plurality of lubricating grooves for filling solid lubricants, and the shaft necks of the tripod stands are directly contacted and lubricated with the spherical rings through the solid lubricants; and the upper part of the three-pin frame shaft neck is provided with a retaining ring groove for mounting a steel wire retaining ring.
As a preferable technical scheme, the number and the size of the lubricating grooves can be adjusted according to specific working conditions.
The invention has the beneficial effects that:
1. the invention is a self-lubricating tripod without coating lubricating grease between the ball ring and the rolling pin during assembly;
2. lubricating grease, the rolling needles and the rolling needle retainer rings are not used, and inclined planes for propping the rolling needles and round corners for preventing interference are not required to be designed at the roots of the three-pin frames, so that the structure of the universal joint is simplified, the assembly is convenient, the manufacturing difficulty is reduced, and the manufacturing cost is reduced;
3. the universal joint has the advantages that the rolling needles are not used, the shaft diameter of the cross shaft can be increased, the strength is increased, and the service life of the tripod universal joint is prolonged.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a partially enlarged view of the region I in fig. 1.
Description of reference numerals: the ball-and-socket joint comprises a tripod 1, a ball ring 2, a lubricating groove 2-1, a steel wire retainer ring 3 and a retainer ring groove 3-1.
Detailed Description
The invention will be described in detail below with reference to the following drawings:
example (b): as shown in the attached drawing, the self-lubricating cylindrical tripod ball mainly comprises a tripod frame 1 and a ball ring 2 sleeved on each tripod frame of the tripod frame 1, wherein the inner wall of the ball ring 2 is uniformly provided with a plurality of lubricating grooves 2-1 for filling solid lubricant, and the shaft neck of the tripod frame 1 is directly contacted and lubricated with the ball ring 2 through the solid lubricant; and the upper part of the shaft neck of the tripod 1 is provided with a retainer groove 3-1 for mounting a steel wire retainer ring 3.
As a preferable technical scheme, the lubricating groove 2-1 can be a round hole or a groove, and the number and the size of the lubricating groove can be adjusted according to specific working conditions and structures.
The working principle of the invention is as follows: the invention provides a mode of punching the lubricating groove 2-1 on the inner wall of the ball ring 2 and filling the lubricating groove with the solid lubricant, and effectively solves the industrial problems that the three-ball pin universal joint roller pin is fragile, lubricating grease is required to be used during assembly, and the manufacturing difficulty is high. When the surfaces of the ball ring 2 and the shaft neck of the tripod 1 move, a thin lubricating film is quickly formed between the generated friction surfaces due to the filled solid lubricant, and because the shearing strength is low, the adhered shearing is generated in the film during sliding, the friction (namely the outer wall of the shaft neck and the inner wall of the ball ring) originally generated between metals is changed into the friction between the solid lubricant, so that the ball ring can play a good lubricating role without adopting a roller pin. In addition, because the rolling needles are omitted, the shaft diameter of the cross shaft can be increased in the design process, so that the strength is improved, and the service life of the tripod universal joint is prolonged.
It should be understood that equivalent substitutions and changes to the technical solution and the inventive concept of the present invention should be made by those skilled in the art to the protection scope of the appended claims.
