Synchronous speed control mechanical device based on coaxiality and opposite rotating directions

Abstract

The invention discloses a synchronous speed control mechanical device based on coaxiality and opposite rotating directions, and belongs to the technical field of mechanical transmission equipment. Thesynchronous speed control mechanical device can be installed between a first rotating shaft and a second rotating shaft, and comprises a first coaxial positioning pipe fixedly connected with the first rotating shaft, a second coaxial positioning pipe fixedly connected with the second rotating shaft, a nut seat fixedly connected to the second coaxial positioning pipe, a reciprocating lead screw shaft assembled on the nut seat in a screwed mode, and a rotating transmission structure arranged between the reciprocating lead screw shaft and the first coaxial positioning pipe, wherein when the reciprocating lead screw shaft is matched with the nut seat to rotate, the reciprocating lead screw shaft can reciprocate. The device can keep coaxial, opposite-direction and same-speed rotation through the nut seat and the reciprocating lead screw shaft, then coaxial, opposite-rotating-direction and same-speed rotation between the first rotating shaft and the second rotating shaft is effectively achieved through transmission, the installation structure is simple and can be achieved coaxially, and the function flexibility of installation equipment and the overall function practicability are improved.

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. [0003] Aiming at the abov...
