Description of drawings:
Fig. 1 is the structural representation that partly cuts open of the present utility model;
Fig. 2 is the B-B sectional structure schematic representation of Fig. 1.
Embodiment: by Fig. 1 and Fig. 2 as can be known, left half-clutch 2 engage sleeves that are set with power transmission steel ball 4 are contained in the right semi-clutch 3 that is set with buffering steel ball 5.The outer wall that inner right side is the left half-clutch 2 of drum type is provided with 3 hemispherical pits 8, power transmission steel ball 4 engage sleeves are contained in 3 hemispherical pits 8 of outer wall of left half-clutch 2, the spring of the bottom of the pit 8 of left half-clutch 2 is installed pocketed springs in the cylindrical hole 10, touches mutually with the inwall of right semi-clutch 3 to guarantee power transmission steel ball 4.The inwall of right semi-clutch 3 is provided with 3 horizontal rows and to buffering steel ball cylindrical hole 9 is installed, the outer end inner wall that buffering steel ball is installed cylindrical hole 9 is provided with screw thread, be used for the adjustment screw 7 that suit cooperates with it, buffering steel ball is installed the outer end internal diameter of the inner bottom internal diameter of cylindrical hole 9 less than buffering steel ball installation cylindrical hole 9, each buffering steel ball is installed in the cylindrical hole 9 and is cooperated suit buffering steel ball 5 from the inside to the outside successively, spring 6 and adjustment screw 7, make the center of the buffering steel ball [5] after the assembling in right semi-clutch 3, show to keep, to guarantee that buffering steel ball 5 does not drop out, guarantee that simultaneously buffering steel ball 5 remains on the inner port that is sleeved on buffering steel ball installation cylindrical hole 9.Every row installs 6 buffering steel balls 5, per from left to right 2 is one group by the opening end of right semi-clutch 3, the outside dimension of every group of buffering steel ball is identical, and the internal diameter that the buffering steel ball of each group is installed cylindrical hole 9 increases one by one, and buffering steel ball 5 is installed cylindrical hole 9 with each buffering steel ball and matched.Engage sleeves is equipped with pad between the spring in buffering steel ball 5 in pit 8 and the spring installation cylindrical hole 10, is in order to prevent the wearing and tearing of buffering steel ball 5 and spring.
When the needs clutch, pass through operating mechanism, driving left half-clutch 2 is moved right by the position that power transmission steel ball 4 diagrams go up the place, the moment of torsion of organizing transmission predetermined when each, power transmission steel ball 4 is entered between a certain group of buffering steel ball successively, then power transmission steel ball 4 contacts with two steel balls of this group and transmits equivalent twisting moment and can compensate axial displacement and drift angle displacement between the diaxon, and radial displacement is guaranteed by the radial clearance between the table in power transmission steel ball 4 and the outer part 3.Power transmission steel ball 4 is approaching more or enter between the maximum pool of buffer steel ball of outside dimension, and then the moment of torsion of Chuan Diing is big more or maximum, and then this device is the classification safety clutch.When making power transmission steel ball 4 enter arbitrary buffering steel ball group by operating mechanism, when the moment of torsion that transmits is organized predetermined torque value above this, then power transmission steel ball 4 will be organized between two buffering steel balls at this and slip over, and overload stops the effect that transmission is an overload protection automatically thereby reach step by step; When power transmission steel ball 4 entered big or maximum outside diameter size buffering steel ball group, less outside dimension buffering steel ball group all can play the obviously effect of buffering, vibration damping, and then this device is a classification buffer shock-absorbing safety clutch.1 is dustproof, grease proofing rubber cover.
When the needs safety clutch separates, can make left half-clutch 2 to moving to left by operating mechanism, power transmission steel ball 4 returns illustrated idle loop position and is separated state.
