The utility model has the advantages of smaller abrasion, longer service life, easy checking and maintaining, etc. The utility model is the equispeed universal joint which is favorably eliminated stress centralization.
Description
Technical field
The utility model relates to a kind of universal joint, especially a kind of structure improvement of constant velocity universal joint.
Technical background
In common constant velocity universal joint, the moment of universal joint is transmitted by spherical ball, and this spherical ball is located between inner ring and the outer ring, and is not limited in the hole upward uniform between the ball.When universal joint is worked, go up between ball and the ball between the edge in hole to some contact, very easily produce stress and concentrate, thus a certain parts of destruction universal joint.The stress of comparatively concentrating has also quickened the wearing and tearing of ball in addition, has further reduced the working life of universal joint.And the universal joint of said structure also is not easy to maintenance, has therefore reduced troubleshooting of faults efficient, incurs loss through delay man-hour.
Summary of the invention
The utility model has solved and has been easy to generate stress in the universal joint operation process that prior art exists and concentrates, it is more serious to wear and tear, and the technical problem that universal joint working life is short etc. provides a kind of stress of having eliminated to concentrate, reduce wearing and tearing, and increased a kind of constant velocity universal joint in working life.
The utility model has solved the technical problem of the difficult maintenance that prior art exists etc., and a kind of maintenance and the efficient of fixing a breakdown higher constant velocity universal joint of being easy to is provided.
Above-mentioned technical purpose of the present utility model mainly is by technological scheme solution once: a kind of constant velocity universal joint, comprise the outer ring, inner ring, be located at ball support and ball between outer ring and the inner ring, it is characterized in that being cylindrical body in the middle of the described ball, two ends are spheroid, and the described two ends that are spheroid have the same centre of sphere, and radius of sphericity is greater than the radius of ball mediate cylindrical; Evenly be provided with several grooves on the outside of described inner ring, the inner edge of described outer ring is provided with the groove of similar number, described ball support is provided with and inner ring and the corresponding hole of outer ring upper groove, described ball be located in this hole with Internal and external cycle on contact grooves.On one, the outer ring is structure as a whole with the axle that is positioned at the universal joint end described inner ring by key and snap fit, and the groove on the inner ring is evenly arranged, the curved outer surface of non-groove part.Groove number on the outer ring equates with the number of inner ring upper groove, and the line of centres of two grooves is by the center of inner ring and outer ring.Hole uniform on the ball support is corresponding one by one with groove, and ball is embedded in this hole, and the spheroid at ball two ends contacts with Internal and external cycle by the groove on the Internal and external cycle, and the cylindrical body in the middle of the ball matches with hole on the ball support, and is the line contact between the two.
As preferably, the centre of sphere of described ball two ends spheroid be positioned at the perpendicular plane of described cylindrical body on, and this plane is by cylindrical center.That is, the barrel portion of described ball and spheroid part coaxial line, center altogether, this structure makes ball have good stability, and two ball-shaped end of ball be easy to Internal and external cycle on groove coincide.
As preferably, described groove is curved, and its radius of arc is slightly larger than the radius of ball two ends spheroid, and this structure has improved the anastomose property between ball end and the Internal and external cycle.
As preferably, it is straight line that there are two opposite side in the hole on the described ball support, and the distance of two opposite side approximates cylindrical diameter, and this structure has reduced the wearing and tearing of ball, has prolonged the working life of ball.
As preferably, described cylindrical height is about 1/5～1/4 of described ball whole height.
As preferably, the diameter of described ball column part approximates the diameter of former spherical ball, and therefore when changing when using ball described in the utility model, former ball support still can continue use.
Therefore, it is less to the utlity model has wearing and tearing, and working life is longer, be easy to characteristics such as maintenance, is a kind of concentrated constant velocity universal joint of stress of having eliminated well.

Accompanying drawing 3 is part section enlarged views of accompanying drawing 1.
Specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: shown in accompanying drawing 1 and accompanying drawing 3, described constant velocity universal joint 1 comprises outer ring 6, and inner ring 2 is located at ball support 16 and ball 12 between outer ring 6 and the inner ring 2.Inner ring 2 is fixed on one 5 by key 3 and buckle 4, and outer ring 6 is structure as a whole with the axle 7 that is positioned at the universal joint end.Evenly be provided with several arc grooves 9 on the outside of inner ring 2, the curved outer surface 8 of non-groove part, the inner edge of outer ring 6 is provided with the arc groove 11 of similar number, and the line of centres of two arc grooves is by the center of inner ring 2 and outer ring 6.Ball support 16 be provided with inner ring 2 and outer ring 6 on arc groove 9 and 11 corresponding holes 17.Be cylindrical body 13 in the middle of the described ball 12, two ends are spheroid 14 and 15, the described two ends 14 and 15 that are spheroid have the same centre of sphere, the spheroid radius is greater than the radius of ball mediate cylindrical 13, the diameter of cylindrical body 13 approximates the distance of these 17 liang of opposite side in hole, and two spheroids 14 and 15 and mediate cylindrical 13 coaxial lines, center altogether.Arc groove 9 and 11 radius of arc are slightly larger than the radius of arc of ball spheroid place sphere, and the height of ball cylindrical body 13 parts accounts for 1/5 of ball 12 whole heights.Ball 12 is embedded in the hole 17 on this ball support 16, the spheroid 14 at ball two ends and 15 contacts with Internal and external cycle by the groove on the Internal and external cycle 9 and 11, on cylindrical body 13 in the middle of the ball and the ball support match (as shown in Figure 2) in hole 17, and be the line contact between the two, changed traditional some contact, concentrate so eliminated stress, reduced wearing and tearing, and prolonged the working life of universal joint.Because the diameter of ball cylindrical body 13 parts approximates the diameter of former spherical ball, therefore when changing use ball described in the utility model, former ball support still can continue to use.
