A driving device for a frame-type large-load rotating mechanism

Abstract

A driving device of a frame type large-load rotating mechanism mainly comprises a driving motor, a connecting piece, a lead screw base, a lead screw, a gantry, a rotary device assembly, a transition piece, a rotating shaft, a rotating shaft base support, a fixing plate, an inner frame and an outer frame. The lead screw is fixedly connected with a motor shaft of the driving motor through the connecting piece. The lead screw base is fixed above the outer frame through the gantry. A lead screw nut and a lead screw nut base are assembled into the rotary device assembly. The lead screw is connected with the inner frame through the transition piece. One end of the transition piece is fixed to the inner frame, and the other end of the transition piece is connected with the lead screw through the rotary device assembly. The rotating shaft bears the weight of a carrier, the weight of the inner frame and the weight of corresponding accessory structures, one end of the rotating shaft is fixed above the outer frame through the rotating shaft base support, and the other end of the rotating shaft is fixedly connected above the inner frame through the fixing plate. The driving motor drives the lead screw to rotate, and the inner frame and a load are driven to rotate relative to the outer frame around the rotating shaft through the rotary device assembly and the transition piece. Due to the design, the requirements for torque and power of a driving part are lowered, and the size, weight and cost of the motor and a driving device are greatly reduced.

Description

technical field [0001] The invention relates to a driving device of a frame-type large-load rotating mechanism. The rotating driving device is an important part of many machines, and it has the functions of satisfying forward and reverse rotation of mechanical equipment, stable braking, and safe and reliable operation. Background technique [0002] The driving device of the rotating mechanism is a transmission device that realizes the power and speed of the rotating part of the mechanical equipment relative to the non-rotating part. The form and structure of the rotary drive mechanism are mainly determined according to the use, working characteristics and load weight of the mechanical equipment. For the frame-type large-load rotating mechanism, in order to ensure the reliable operation of the rotating mechanism and prevent overload, the rotating mechanism must overcome the following moments from the perspective of force: eccentric moment, inertia moment, and disturbance mome...

AI Technical Summary

Problems solved by technology

Due to the relatively large driving torque required, the motor needs to have a large output torque when directly driven by the motor, resulting in large power, large volume, heavy weight, and high cost of the motor. In practical applications, it is restricted by the mechanical structure design of the rotating mechanism and other indicators. limit
