Automatic mechanical arm belt wheel transmission mechanism

Abstract

The invention provides an automatic mechanical arm belt wheel transmission mechanism, and relates to the technical field of mechanical transmission structures. The problems that automatic air collection type cooling of a belt cannot be automatically realized in the transmission process through structural improvement, and other structures cannot be linked to realize automatic cooling during working through structural improvement are solved. The automatic mechanical arm belt wheel transmission mechanism comprises a base body; a first transmission structure, a second transmission structure, a third transmission structure and an auxiliary structure are rotationally connected to the base body; a through hole A is obliquely formed, and the inclination angle is -45 degrees, so that heat dissipation of a belt A can be realized when air is sprayed from the through the through hole A, and the through hole A formed at -45 degrees can reduce the resistance during rotation of a fourth rotating shaft and the friction force on the belt A; the inclination angle of through holes B is 45 degrees, and the through holes B formed in the annular array form an air collecting structure of the fourth rotating shaft, so that automatic air collection can be performed through the through holes B when the fourth rotating shaft rotates.

Description

technical field [0001] The invention belongs to the technical field of mechanical transmission structures, and more specifically relates to an automatic mechanical arm pulley transmission mechanism. Background technique [0002] With the continuous development of science and technology, the mechanical arm gradually replaces manual labor, and the mechanical arm often realizes the transmission work through multiple transmission structures when it is working. [0003] For example, the application number: CN201120366766.3, this utility model is an automatic mechanical arm pulley transmission mechanism, including a driving motor, a main pulley cooperating with the driving motor, and a first idler pulley and a second idler pulley located on both sides of the main pulley. The third idler pulley and the passive pulley, the third idler pulley and the passive pulley are flexibly wound together with the original main pulley, the first idler pulley and the second idler pulley through a ...

Problems solved by technology

[0007] In order to solve the above technical problems, the present invention provides an automatic mechanical arm pulley transmission mechanism to solve the existing problem that the belt of the existing device tends to heat up during the transmission process, and if the belt is in a high temperature state for a long time, the life of the belt is likely to be shortened , but cannot automatically realize the automatic cooling of the belt during the transmission process through structural improvements; moreover, the pulley tends to heat up under continuous working conditions, and it cannot be achieved through structural improvements while working. The problem of linkage with other structures to realize automatic cooling
