Abstract

The invention relates to the field of transmission devices, in particular to a cam transmission device and a stage using the cam transmission device. It includes a lifting table, a scissor-type lifting device, a mounting plate, a rotating shaft, and a turntable with a vortex groove. The lower end of the rotating shaft is frictionally matched with the vortex groove. Under the friction fit of the shape groove, the rotating shaft is pushed away from the main shaft and rotates at the same time, and the speed of the rotating shaft will increase with the increase of the radius of rotation of the mating part. Driven by the meshing drive of the driving gear and the driving rack, the speed of the sliding plate away from the main shaft will gradually increase. Driven by the transmission assembly, the lower end of the first strut and the lower end of the second strut are accelerated close together, thus providing a speed compensation for the slower and slower rising speed of the lifting platform, so that the lifting platform keeps rising at a uniform speed, and realizes the lifting platform Even and gentle rise.

Description

technical field [0001] The invention relates to the field of transmission devices, in particular to a cam transmission device and a stage using the cam transmission device. Background technique [0002] In machining and application, the transmission device is often used, and the transmission device (Transmission device) transmits the power of the power device to the intermediate equipment such as the working mechanism. However, in the prior art, the transmission device used in the lifting mechanical equipment has a simple structure and a single function, and the power transmission efficiency is low, it is easy to get stuck, and even a safety accident of lifting failure occurs, which has a relatively large adverse effect. [0003] Furthermore, the stage provides an important device for the actors in the theater to perform, in order to create a lively three-dimensional performance effect. In modern stage design, lifting stage and scissor-type lifting structure are often used ...
