Description

A kind of ball with oil guide groove

Technical field

The utility model relates to field of mechanical technique, specially a kind of ball with oil guide groove.

Background technique

Cage is also constant velocity cardan joint, is the important component in car drive system, and cage is divided into internal spherical cage and external ball cage, For internal spherical cage, three ball pin assemblies are core components, and the torsion for transmitting engine mission plays particularly significant Effect, existing constant speed universal joint inner ball cage is by interior ball shell, the composition such as three ball pin assemblies and entering spindle, wherein three balls Pin assembly includes spider, is installed on spider and be spaced apart from each other 120 degree of three pin shafts, is set with ball, ball on pin shaft Lateral wall and the inner sidewall of internal spherical cage shell be spherical surface, in the rotation of three ball pins, the lateral wall of ball can with outside internal spherical cage The inner sidewall of shell is in contact and generates friction, so that the lateral wall of ball be made to be worn, while three ball pin balls its interior cylinders Face contacts friction with the spider cylinder of three ball pins in three ball pin ring of universal joint, substantially reduces the service life of universal joint, unfavorable In long-run development, such ball is also unable to satisfy the demand in present market, for this purpose, we have proposed a kind of with oil guide groove Ball comes into operation, to solve the above problems.

Utility model content

The purpose of this utility model is to provide a kind of balls with oil guide groove, to solve to propose in above-mentioned background technique The problem of.

To achieve the above object, the utility model provides the following technical solutions: a kind of ball with oil guide groove, including this Body, the outside of the ontology are equipped with the oil guide groove of Spiral distribution, are fixedly installed with multiple groups thermal vias in the inner cavity of the ontology, The inner ring front and rear sides of the ontology are equipped with ball, and ball runs through ontology, and the ball is located at two adjacent groups thermal vias Between, the outside of the ball is equipped with fixing groove.

Preferably, the fixing groove includes groove body, and the groove body is equipped with taper card slot, and taper card slot is equipped with lubrication Oil hole is uniformly equidistantly fixedly installed with three groups of oil storage tanks on the groove body.

Preferably, the interior cavity wall of the groove body is equipped with puigging.

Preferably, the thermal vias runs through ontology, and the two sides of thermal vias are equipped with filter screen.

Compared with prior art, the utility model has the beneficial effects that

1, the lateral wall that the oil guide groove being equipped on the outside of ball can reduce ball can be in contact with the inner sidewall of internal spherical cage shell Lubrication is played the role of at place, thus the abrasion that the lateral wall for reducing ball is subject to.

2, the setting of ball, be conducive to ball in the process of movement, prevent its inner cylinder face of ball and three ball pins Spider cylinder directly contacts friction, is replaced using rotatable ball, reduces the loss of mechanical energy.

3, the setting of fixing groove is conducive to for ball being fixed, prevents ball from spilling, at the same in fixing groove oil storage tank and The setting for lubricating oil hole, can proceed to the lubricating oil inside ball in fixing groove, play lubricating action, and storage to ball Oil groove can store lubricating oil, can be lubricated for a long time to ball, reduce time that staff refuels to ball Number, alleviates the workload of staff, improves work efficiency, and puigging is equipped in fixing groove, ball can be reduced and move The noise generated in the process.

4, the setting of thermal vias is conducive to evacuate the heat for the generation that rubs in ball motion process, and heat dissipation is logical The setting of filter plate prevents dust to enter in through-hole the blocking for causing thermal vias on hole, and extend the present apparatus uses the longevity Life.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-4 is please referred to, the utility model provides a kind of technical solution: a kind of ball with oil guide groove, including ontology 1, the outside of the ontology 1 is equipped with the oil guide groove 2 of Spiral distribution, and it is logical that multiple groups heat dissipation is fixedly installed in the inner cavity of the ontology 1 Hole 3, the inner ring front and rear sides of the ontology 1 are equipped with ball 5, and ball 5 runs through ontology 1, and the ball 5 is located at two adjacent groups Between thermal vias 3, the outside of the ball 5 is equipped with fixing groove 4.

Wherein, the fixing groove 4 includes groove body 41, and the groove body 41 is equipped with taper card slot 42, and on taper card slot 42 Equipped with lubrication oil hole 44, it is uniformly equidistantly fixedly installed with three groups of oil storage tanks 43 on the groove body 41, the setting of fixing groove 4, Be conducive to for ball 5 being fixed, prevent ball 5 from spilling, while oil storage tank 43 and lubrication oil hole 44 are set in fixing groove 4 It sets, the lubricating oil inside ball can be proceeded in fixing groove 4, playing lubricating action and oil storage tank 43 to ball 5 can will moisten Lubricating oil storage, can for a long time be lubricated ball 5, reduce the number that staff refuels to ball, alleviate The workload of staff, improves work efficiency；The interior cavity wall of the groove body 41 is equipped with puigging, sets in fixing groove 4 There is puigging, the noise that ball 5 generates during the motion can be reduced；The thermal vias 3 runs through ontology 1, and thermal vias 3 Two sides be equipped with filter screen, the setting of thermal vias 3 is conducive to dredge the heat for the generation that rubs in ball motion process It dissipates, the setting of filter screen prevents dust to enter in through-hole the blocking for causing thermal vias 3 on thermal vias 3, extends this dress The service life set.

Working principle: three balls are fixedly mounted on three pin shafts of three ball pins respectively, and in the outside of three ball pins It is cased with internal spherical cage shell, then ball normal rotation can be run on pin shaft, during rotation, outer due to ball ontology 1 Side wall is in contact with the inner sidewall of internal spherical cage shell, since the lateral wall of ontology 1 is equipped with the oil guide groove 2 of Spiral distribution, can incite somebody to action Lubricating oil inside three ball pins is uniformly covered on the outside of ontology 1 by oil guide groove 2, reduces 1 outside of ontology and internal spherical cage The friction of the inner sidewall of shell, while can allow ball that can work down with normal rotation by being equipped with ball 5 in the inner ring of ontology 1, it allows There is a certain distance between the inner ring of ontology 1 and the pin shaft of three ball pins, prevents the inner ring of ontology 1 and the pin shaft generation of three ball pins from rubbing It wipes, the lubricating oil in the inside of ontology 1 can be entered in fixing groove 4 by lubricating oil hole 44, the work being lubricated to ball 5 With and oil storage tank 43 lubricating oil can be stored, ball 5 can be lubricated for a long time, the utility model is convenient to use, Design rationally, has very strong practical value.
