Abstract
The utility model discloses a three-pin shaft assembly with combined knuckle bearings and sliding bearings. The three-pin shaft assembly with the combined knuckle bearings and sliding bearings comprises a three-pin frame, wherein each sliding bearing is sleeved outside each pin shaft of the three-pin frame, each sliding bearing is in interference fit with the three-pin shaft, each knuckle bearing is sleeved outside each sliding bearing, and each knuckle bearing is in clearance fit with each sliding bearing. The utility model further discloses a three-pin shaft constant velocity universal joint which comprises a driving shaft, a driven shaft, a groove shell and the three-pin shaft assembly, wherein the driving shaft is connected with a spline of the three-pin frame, a groove which is matched with each knuckle bearing is formed in the inner portion of one end of the groove shell, and the other end of the groove shell is connected with the driven shaft. The three-pin shaft assembly with the combined knuckle bearings and sliding bearings and the universal joint of the three-pin shaft assembly have the advantages of being small in number of parts, low in manufacturing cost, high in assembly efficiency, strong in bearing capability, and long in service life.
Description
Technical field
The utility model relates to three Assembly of pin, specifically is three Assembly of pin of a kind of joint shaft bearing and sliding bearing combination; Also relate to the universal joint that has adopted this three Assembly of pin simultaneously.
Background technique
Three Assembly of pin of conventional construction comprise spider and ball, and the axis of three bearing pins is distributed on the same plane on the spider; Ball is the outer spherical surface of symmetry, and the ball internal diameter is by completely adorning on the needle roller assembling bearing pin, and ball can rotate around bearing pin.
The internal spline of spider is connected with splined shaft, and splined shaft is a driving shaft; Three Assembly of pin are placed in the pot shell, and pot shell is connected with driven shaft; Driving shaft drives driven shaft by three Assembly of pin and rotates.
For preventing that needle roller and ball from coming off at work, specialized designs three opening jump rings, place three jump ring grooves at three bearing pin tops of spider, corresponding again structure of joining three punching press back-up rings respectively.
Show that through use following deficiency is arranged:
(1) three Assembly of pin parts of conventional construction are too many, the manufacture cost height, and assembly process is many and complicated, and efficiency of assembling is low.
(2) the conventional construction ball is undersized, and bearing capacity reduces.
(3) very high to physical dimension, precision, intensity and the toughness reguirements of punching press back-up ring, owing to be sheet stamping, be prone to crackle and breakage causes needle roller to come off.
(4) because three bearing pins of spider must grinding, and each axle journal place all will process a grinding wheel groove, each top also will process a jump ring groove, has increased the operation process of spider, has also increased the difficulty of cost and quality control.
(5) because needle roller is that line contacts with ball, and bearing capacity is low, and needle roller very easily damages, these three Assembly of pin life-spans that show conventional construction are low.
The model utility content
In order to overcome the deficiencies in the prior art, the utility model discloses three Assembly of pin of a kind of joint shaft bearing and sliding bearing combination, this Assembly of pin part is few, low cost of manufacture, efficiency of assembling height, bearing capacity strong, long service life.
The utility model has adopted following technological scheme:
Three Assembly of pin of joint shaft bearing and sliding bearing combination comprise spider, and the bearing pin of spider is arranged with a sliding bearing outward respectively, sliding bearing and three bearing pin interference fit; Sliding bearing is arranged with a joint shaft bearing outward respectively, joint shaft bearing and sliding bearing Spielpassung.
Three sliding bearings are pressed into respectively on three bearing pins of spider, then three joint shaft bearings are installed to respectively on the external diameter of sliding bearing, form three Assembly of pin of the present utility model.
The invention also discloses a kind of three bearing pin constant velocity universal joints, comprise driving shaft, driven shaft, pot shell and aforesaid three Assembly of pin, driving shaft is connected with the spider spline; Pot shell one end inside is provided with the raceway groove that cooperates with joint shaft bearing, and the pot shell the other end is connected with driven shaft.
Three Assembly of pin are inserted in the spider, again three Assembly of pin are placed in the pot shell, thereby constitute constant velocity universal joint.
The utility model has been cancelled jump ring, punching press back-up ring and the needle roller of three Assembly of pin of conventional construction, replaces three groups with three sliding bearings and completely adorns needle roller, replaces three balls with three joint shaft bearings.
The beneficial effects of the utility model are: steadily, flexibly, reliably and accurately transmitting movement and moment of torsion, and compact structure, rationally, improve bearing capacity, and be convenient to processing and check, improve processing and efficiency of assembling.
Description of drawings
Fig. 1 is a plan view of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Number in the figure: 1-joint shaft bearing, 2-sliding bearing, 3-spider, 4-bearing pin, 5-internal spline.
Embodiment
Below in conjunction with drawings and Examples model utility is described further:
As depicted in figs. 1 and 2, three Assembly of pin of joint shaft bearing and sliding bearing combination comprise spider 3, the bearing pin 4 outer sliding bearings 2, sliding bearing and three bearing pin interference fit of being arranged with respectively of spider; Sliding bearing is arranged with a joint shaft bearing 1 outward respectively, joint shaft bearing and sliding bearing Spielpassung; The spider inwall is provided with internal spline 5.
A kind of three bearing pin constant velocity universal joints comprise driving shaft, driven shaft, pot shell and aforesaid three Assembly of pin, and driving shaft is provided with the external splines that cooperates with the internal spline of spider; Pot shell one end inside is provided with the raceway groove that cooperates with joint shaft bearing, and the pot shell the other end is connected with driven shaft.Driving shaft is with after the spider spline is connected, and three Assembly of pin are inserted raceway groove in the pot shell, promptly forms universal joint.
This patent product loads moment of torsion and has improved 13.3% than industry standard through test, and frequency accelerates 50%, and product does not have any damage; Durability (life-span) improves more than 17%.A series of test result show that this patent reliability of products and life-span have had significantly improves.
Claims (2)
1. three Assembly of pin of joint shaft bearing and sliding bearing combination is characterized in that comprise spider, the bearing pin of spider is arranged with a sliding bearing outward respectively, sliding bearing and three bearing pin interference fit; Sliding bearing is arranged with a joint shaft bearing outward respectively, joint shaft bearing and sliding bearing Spielpassung.
2. a bearing pin constant velocity universal joint is characterized in that, comprises driving shaft, driven shaft, pot shell and three Assembly of pin as claimed in claim 1, and driving shaft is connected with the spider spline; Pot shell one end inside is provided with the raceway groove that cooperates with joint shaft bearing, and the pot shell the other end is connected with driven shaft.
