Large-torque hollow rotating platform

Abstract

The invention relates to the technical field of rotating platforms, and discloses a large-torque hollow rotating platform which comprises a hollow rotating platform body and a box body, the top of the box body is provided with an opening, the hollow rotating platform body is arranged above the box body, and a damping device is arranged in the box body. The piston slides in the air pipe to extrude or expand air in the air pipe, so that air resistance is generated, the air slowly enters or is exhausted from the two exhaust holes, preliminary vibration reduction is achieved, vibration reduction is further achieved through the elastic force action of the two first springs in cooperation with the elastic force action of the two second springs, and the vibration reduction effect is improved. And meanwhile, resilience force of two first springs and two second springs is continuously weakened through air resistance generated by sliding of the piston, the stability of the damping device is enhanced, and the effect that the hollow rotating platform body is prevented from being damaged due to vibration caused by long-time operation of the hollow rotating platform body is achieved.

Description

technical field [0001] The invention relates to the technical field of rotating platforms, in particular to a hollow rotating platform with high torque. Background technique [0002] The hollow rotating platform is a new type of reducer product, which can obtain different output speeds according to different reduction ratios. It is suitable for a variety of rotating motion occasions, and because the hollow rotating platform has the characteristics of high rigidity, high precision and better output effect, etc. , is widely used in punching machine, laser engraving machine, CCD measurement, automatic assembly and need to use indexing motion and alignment angle rotation and other occasions; At present, the hollow rotating platform generally rotates by starting the motor to drive the gear transmission, however When the motor is running, it will generate large vibration, and the hollow rotating platform is easily damaged due to vibration under long-term use.
