Synchronous speed control mechanism based on coaxial center and reverse direction

Abstract

The invention discloses a synchronous speed control mechanical device based on a coaxial center and reverse direction, and belongs to the technical field of mechanical transmission equipment. It can be installed between the first rotating shaft and the second rotating shaft, including: a first coaxial positioning tube, which is fixedly connected to the first rotating shaft; a second coaxial positioning tube, which is fixedly connected to the second rotating shaft; a nut seat , which is fixedly connected to the second coaxial positioning tube; the reciprocating screw shaft, which is screw-fitted to the nut seat, and when it rotates with the nut seat, the reciprocating screw shaft can move back and forth; the rotary transmission structure, which is set Between the reciprocating screw shaft and the first coaxial positioning tube. The device can maintain the coaxial center, opposite direction and same speed rotation through the nut seat and the reciprocating screw shaft, and then effectively realize the coaxial center, opposite direction and same speed rotation between the first rotating shaft and the second rotating shaft through transmission. It is simple and can be realized in the same axis, which improves the functional flexibility of the installed equipment and the overall functional practicability.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission equipment, in particular to a synchronous speed control mechanical device based on coaxial centers and reverse direction. Background technique [0002] At present, in mechanical transmission equipment, for two coaxial shafts that rotate in opposite directions and require synchronous speed at the same time, gears are often used to achieve very complex multi-stage cooperation, and planetary gears are also used to cooperate with gears, but the planetary The sun gear and the outer ring gear of the sun gear can only achieve the coaxial center and reverse direction. Due to the difference in the number of teeth between the two, it still needs to be realized by combining the auxiliary gear. The structure is complex and cannot be directly realized at the coaxial center, resulting in The functional flexibility of existing mechanical transmission equipment is low.
