Abstract
A shaft coupling allowing relative angular displacement between two coupled shafts comprises two sleeves and a middle coupling sleeve, wherein one sleeve is fixed on one side of the middle coupling sleeve, the other sleeve is arranged in the middle coupling sleeve through a gland, steel balls are jointly arranged in grooves on the outer side of the end part of the sleeve and the inner side of the middle coupling sleeve, a steel ball is arranged in a groove at the bottom of the middle coupling sleeve, and a thrust top disc is arranged at the end part of the sleeve arranged in the middle coupling sleeve. The utility model discloses can allow the two interaxes to have the angle displacement that is less than 3, the preparation installation is easy, long service life to can bear great axial thrust and axle load.
Description
The utility model relates to movable coupling technical field, more particularly relates to a kind of coupling of allowing the axle change angular dependence of two coaxial lines when motion.
Existing permission diaxon when motion has the rigid coupling of angular displacement to mainly contain Hooks coupling universal coupling and gear coupling, and the angular displacement that the former allows is bigger, but complex structure, installation precision requires high; And the angular displacement that the latter allows is too little, and rotator inertia is big, thereby the application of the two all has certain narrow limitation.What another kind of use can allow angular displacement more widely is elastic coupling flexible coupling, but its shortcoming is to use the life-span short.And all can not bearing axial pushing force and axle load with upper coupling.
The purpose of this utility model is a kind of long service life of design, can allows certain angular displacement and can bear the coupling of larger axis to thrust and axle load.
The technical solution of the utility model is: it has two sleeves and a middle joint sleeve, and an end of one of them sleeve has flange, a side of joint sleeve in the middle of being fixedly mounted on by fixing bolt; The outside of another sleeve one end has the step projection, be installed in the middle joint sleeve by the gland on the joint sleeve in the middle of being fixed on, and form certain interval with the inwall of middle joint sleeve, the outside of this sleeve ends step projection and the inboard of middle joint sleeve respectively have at least three equally distributed semi-circular recesses, in two-part semi-circular recesses cooperates the circular trough that constitutes steel ball are housed; Bottom centre at middle joint sleeve has a circular groove, and the steel ball of a diameter greater than this depth of groove is housed in the groove; The inboard, end of the sleeve in the middle of being installed in the joint sleeve has annular groove, thrust is housed in the groove takes over a business, and between the step projection in this sleeve outside and gland rubber ring is housed.
Use the utility model, can allow two between centers that angular displacement less than 3 ° is arranged, make and installation precision requires lowly, internal friction power is little, long service life, and can bear bigger end thrust and axle load, thereby wide accommodation.
Accompanying drawing has provided concrete structure of the present utility model, and wherein Fig. 1 is its overall structure schematic representation, and Fig. 2 is the A-A sectional view among Fig. 1.
1 is sleeve among the figure, and 2 is middle joint sleeve, and 3 is another sleeve, and 4 is gland, and 5 is rubber ring, and 6 is the thrust top cover, and 7,8 are steel ball.
In the embodiment that accompanying drawing provides, an end of sleeve 1 has flange, the outside, bottom surface of joint sleeve 2 in the middle of being installed in by fixing bolt.The outside of one end of another sleeve 3 has the step projection, by set screw gland 4 is installed in the end of middle joint sleeve 2, and gland 4 is installed in an end of sleeve 3 in the middle joint sleeve 2, and the end in addition of sleeve 3 is by stretching out in the hole on the gland 4.2 of sleeve 3 and gland 4 and middle joint sleeves are at regular intervals, so that between both axis of sleeve 3 and middle joint sleeve 2 certain angular displacement can be arranged.Between the step projection of gland 4 and sleeve 3 ends, flexible sealing rubber ring 5 is housed.Have equally distributed 5 semi-circular recesses respectively on the outside of sleeve 3 end step projectioies and the inwall of middle joint sleeve 2, in the circular trough that the cooperation of two-part semi-circular recesses forms a steel ball 7 is housed respectively, transmit torsion by these steel balls 7 during work, and allow diaxon that angular displacement is arranged.In middle joint sleeve 2 bottom centre one circular groove is arranged, a steel ball 8 is housed in the groove, the diameter of steel ball 8 also has groove greater than the degree of depth of groove in the end of sleeve 3, the thrust that contacts with steel ball 8 is housed in the groove takes over a business 6, the two common bearing axial pushing force.During use, should be marked with lubricating grease around steel ball 7,8, sleeve 1,3 connects with axle by long key.
