Locating transmission mechanism

Abstract

The invention provides a locating transmission mechanism. The locating transmission mechanism mainly solves the problems that according to an existing locating transmission mechanism, the structure is complicated, the transmission efficiency is low, an output shaft is small, the rigidity is not enough, the bearing capacity and the impact resistance are weak, and the service life is short. The locating transmission mechanism is characterized in that a rotation box is arranged on a fixing frame, the rotating box rotates around the axis of the rotating box, the rotating box is provided with an output face used for being connected with a load, a motor is connected to the rotating box, a first transmission mechanism, a second transmission mechanism and an output piece are arranged in the rotating box, one end of the first transmission mechanism is connected with the motor, the other end of the first transmission mechanism is connected with the second transmission mechanism, and the second transmission mechanism drives the rotating box to rotate synchronously through an output piece. The locating transmission mechanism has the advantages of being simple and compact in structure, light in overall weight, suitable for industrial large-batch production, large in transmission ratio, high in transmission efficiency, small in backlash, high in bearing capacity, high in impact resistance and long in service life and further has the advantages that the output shaft is large, the rigidity is large, and two-end output can be achieved.

Description

technical field [0001] The invention particularly relates to a positioning transmission mechanism. Background technique [0002] The existing positioning transmission mechanisms are widely used in solar power generation devices, radar antenna positioning devices and other fields, and most of them adopt transmission forms such as gear pairs and ball screw pairs. In order to meet the requirement of outputting a large enough torque and consume the power of the motor as small as possible, the total transmission ratio of the transmission device is often required to reach tens of thousands. To meet such a large transmission ratio, for transmission forms such as gears and ball screws, multi-stage transmission is required, and the single-stage meshing gears have a large difference in the number of teeth to meet the large transmission ratio, which seriously affects the service life of the gears and makes the overall The structure is very complex and huge. For transmission forms suc...
