Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-3, an embodiment of the present invention is shown: the main column spinner 1 and the spacing shell 2 that are fixed with main connection flange dish 3 and main stopper 4 respectively including both ends, the circumference side of main column spinner 1 is equipped with the main spiral ball groove 5 of a heliciform and indent formula, 2 inside centers of spacing shell are equipped with a main overlap hole 7, spacing shell 2 is equipped with the vice spiral ball groove 8 of an indent at the edge that lies in main overlap hole 7, the both ends in vice spiral ball groove 8 do not extend to the both ends face of spacing shell 2, be tip seal structure, main overlap hole 7 cup joints the outside at main column spinner 1, the regional intussuseption that vice spiral ball groove 8 and main spiral ball groove 5 coincide is filled with a plurality of balls 10, and a plurality of annular array's reinforcement connecting rod 11 is installed at a terminal surface edge of spacing shell 2, and reinforcement connecting rod 11's an end fixing flange dish 12 contradicts.
The concave depth of the main spiral ball groove 5 is the same as the radius of the ball 10.
The concave depth of the auxiliary spiral ball groove 8 is the same as the radius of the ball 10.
The structure radiuses of the concave cross sections of the main spiral ball groove 5 and the auxiliary spiral ball groove 8 are the same as the radius of the ball 10, so that the relative sliding of the spiral balls is realized, and the spiral progressive relation is realized.
The specific use mode is as follows: in the working process of the invention, a main connecting flange plate 3 is butted with the end part of a driving rotating shaft, a telescopic rod with a rotation transmission function is required to be installed at the end part of a driven shaft, then an auxiliary connecting flange plate 12 is butted with the telescopic rod, when the driving rotating shaft rotates according to a preset direction, a main rotating column 1 rotates, due to the gravity torque resistance of a limiting shell 2, a reinforcing connecting rod 11 and a butting flange plate 12 and the common resistance of the telescopic rod, balls 10 can roll and run in a spiral ball groove 5, similarly, under the action of a spiral structure, the balls 10 can drive the limiting shell 2, the reinforcing connecting rod 11 and the butting flange plate 12 to move to one side, when the limiting shell 2 butts against the side surface of a main limiting block 4, the components can not move transversely due to further rotation, at the moment, the force of the rotation load can be completely acted on the rotation transmission aspect, so as to drive the driven rotating shaft to rotate, the telescopic rotation transmission function of distance is realized.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof.
