Mechanical transmission mechanism

Abstract

The invention discloses a mechanical transmission mechanism. The mechanical transmission mechanism comprises a rack. A main transmission mechanism is arranged in the rack. Auxiliary transmission mechanisms are arranged on the two sides of the main transmission mechanism. A transmission rod is arranged between the main transmission mechanism and each auxiliary transmission mechanism and provided with a first transmission gear. Rectangular transmission bases are arranged on the two sides of the rack and provided with transmission cavities, main driven wheels are arranged on the two sides of the transmission cavities, auxiliary driven wheels are arranged at the four corner positions of each transmission cavity, and the main driven wheels and the auxiliary driven wheels are provided with a transmission chain. Each transmission cavity is internally further provided with a transmission connector internally provided with a second transmission gear, each second transmission gear is provided with a transmission shaft, and each transmission shaft is connected with a mechanical arm. The mechanical transmission mechanism can be applicable to transmission between mechanical transmission and mechanical arms on multiple occasions, the transmission ratio is stable, the transmission performance is stable, the transmission efficiency is high, noise and impacts are low, good safety using performance and the like are achieved, and the actual using requirement is met.

Description

technical field [0001] The invention relates to a mechanical transmission mechanism, which belongs to the technical field of mechanical arms. Background technique [0002] With the development of science and technology, the application of mechanical transmission arms is increasing day by day, and mechanical transmission arms are getting more and more attention. High-precision and high-power transmission output has become the development direction of the industry. [0003] The traditional mechanical transmission arm adopts a toothing method between several connecting arms of unequal length. Toothed transmission is a mechanical transmission that transmits power and motion by means of mutual toothing between gears. It has stable transmission, precise transmission ratio, reliable work, high efficiency, and a wide range of power, speed and size. However, for the gear transmission applied in the mechanical transmission arm, the volume and mass directly restrict its transmission r...

AI Technical Summary

Problems solved by technology

The mechanical transmission arm with belt transmission relies on the friction between the belt and the wheel to realize the transmission, which has good winding properties, can ease the impact and absorb vibration; however, when overloaded, the mechanical transmission arm with belt transmission will slip and cannot Guaranteed transmission ratio, low transmission efficiency and short service life

The mechanical transmission arm of the chain transmission relies on the meshing of the chain and the gear to achieve transmission operation and power. It can be transmitted when the two axes are far apart, and it can work normally under overload and high temperature, and the transmission power is also relatively large; but The transmission ratio is not constant, the transmission is unbalanced, there is a large noise and a large impact force during transmission
