Multifunctional large-torque integrated robot joint

Abstract

The invention provides a multifunctional large-torque integrated robot joint which comprises a direct-current servo motor, a belt wheel set, a gear set, a hollow harmonic reducer, a hollow output shaft, a hollow encoder and a hollow output shaft end bearing. The belt wheel set comprises a large belt wheel and a small belt wheel. The gear set comprises a small gear and a large gear. The direct-current servo motor drives the small belt wheel. The small belt wheel drives the large belt wheel. The large belt wheel is connected with the small gear through a belt wheel shaft. The small gear is engaged with the large gear. One end of the hollow output shaft is connected with the large gear and the hollow encoder, and the other end of the hollow output shaft is connected with the hollow harmonic reducer and an inner ring of the hollow output shaft end bearing. In the multifunctional large-torque integrated robot joint, due to the optimization and combination of the speed reduction ratios of three levels of speed reduction, application requirements in different places and different fields can be met.

Description

technical field [0001] The invention relates to a robot, in particular to a multi-functional high-torque integrated robot joint. Background technique [0002] As the use of robots is becoming more and more widespread, there are robots everywhere in industry, service and other industries, but factors such as after-sales and maintenance of robots are one of the obstacles that hinder the widespread application of robots, making them unable to be used on a large scale. The standardization and modularization of robots will greatly reduce the cost of robots, improve the precision of robots, and simplify the maintenance of robots, which is the trend of robot development and the focus of research. The research on modular joints makes the joints modular and standardized, which will improve the reconfigurability of the robot structure, facilitate the selection and replacement of mechanical arms, reduce costs, reduce weight, improve reliability, and shorten the development and manufact...

AI Technical Summary

Problems solved by technology

The invention has a compact structure and takes up little space, but its structure includes two motors, which increases the difficulty of control; and due to its structural characteristics, its reconfigurable diversity is limited

[0007] Some other modular joints, such as "Space Manipulator Modular Joint" (CN 1807032 A), "Integrated Flexible Rotary Joint" (CN 203371554 U), etc., have the disadvantage that they are only applicable to specific occasions, and cannot be used in many fields. Industry application, it is difficult to achieve cross-industry modular promotion
