Abstract
The utility model discloses a changeable ball shaft coupling of length, including driving part, ball and follower, install the annular plate on the inside wall of driving part, install three locating lever on the annular plate, every the one end that the annular plate was kept away from to the locating lever all runs through the follower setting, locating lever assorted locating hole has been seted up on the follower, it is equipped with the threaded rod to rotate through two spacing rings in the follower, the threaded rod is close to the one end and the annular plate threaded connection of annular plate, set up on the annular plate with threaded rod assorted screw hole, the threaded rod is kept away from the one end of annular plate and is installed hexagon nut in, the follower keep away from one side of annular plate seted up with hexagon nut assorted recess. This scheme has increased the distance between follower and the initiative piece among the ball coupling for interval between them can be adjusted as required, has increased ball coupling's self length, has enlarged ball coupling's application range.
Description
Technical Field
The utility model relates to a ball coupling technical field especially relates to changeable ball coupling of length.
Background
A ball coupling is a flexible coupling without elastic elements. The coupling consists of a coupling half ball with a cylindrical inner surface and a semicircular longitudinal groove and a coupling half with a drum-shaped outer surface and a semicircular longitudinal groove.
The prior art ball coupling has the following disadvantages: the distance that the follower among the ball coupling is for the driving piece is fixed, and the length of ball coupling can't be adjusted promptly for there is the limitation in the ball coupling, consequently needs improve current ball coupling.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects existing in the prior art and providing a ball coupling with variable length.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
changeable ball shaft coupling of length, including driving part, ball and follower, install the annular plate on the inside wall of driving part, install three locating lever on the annular plate, every the one end that the annular plate was kept away from to the locating lever all runs through the follower setting, locating lever assorted locating hole has been seted up on the follower, it is equipped with the threaded rod to rotate through two spacing rings in the follower, the threaded rod is close to annular plate's one end and annular plate threaded connection, set up on the annular plate with threaded rod assorted screw hole, the threaded rod is kept away from the one end of annular plate and is installed hexagon nut in, the follower keep away from one side of annular plate set up with hexagon nut assorted recess.
Preferably, the annular plate is installed at the edge of one side of the driving member close to the driven member.
Compared with the prior art, the beneficial effects of the utility model reside in that:
this scheme has increased the distance between follower and the initiative piece among the ball coupling for interval between them can be adjusted as required, has increased ball coupling's self length, has enlarged ball coupling's application range.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
Referring to fig. 1-4, the variable length ball coupling, including driving part 1, ball 2 and follower 3, install annular plate 6 on the inside wall of driving part 1, install three locating lever 4 on the annular plate 6, the one end that annular plate 6 was kept away from to every locating lever 4 all runs through the setting of follower 3, set up locating lever 4 assorted locating hole 41 on the follower 3, it is equipped with threaded rod 51 to rotate through two spacing rings 53 in the follower 3, threaded rod 51 is close to annular plate 6's one end and annular plate 6 threaded connection, set up on the annular plate 6 with threaded rod 51 assorted screw hole, threaded rod 51 keeps away from the one end of annular plate 6 and installs interior hexagon nut 52, the one side that annular plate 6 was kept away from to follower 3 is seted up with interior hexagon nut 52 assorted recess.
The annular plate 6 is arranged at the edge of one side of the driving piece 1 close to the driven piece 3.
The utility model discloses in, rotate hexagon socket nut 52 and drive threaded rod 51 and rotate, threaded rod 51 mutually supports with the screw hole on the annular plate 6 this moment, can be so that follower 3 along 4 axial displacement of locating lever, and then realized the regulation of driving part 1 with 3 intervals of follower for ball coupling's length can be adjusted according to the demand.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
