Hollow harmonic joint module

Abstract

The invention discloses a hollow harmonic joint module, and relates to the technical field of mechanical modules. According to the hollow harmonic joint module, a motor drives a first gear set to rotate, the first gear set is matched with a first encoding assembly, the rotating speed of the first gear set is detected through the first encoding assembly, so that input rotating speed data of the motor is obtained, an output shaft of the motor is in transmission connection with a speed reducer, the speed reducer drives a transmission shaft to rotate, the transmission shaft drives a second gear set to rotate, and after the motor is decelerated through the speed reducer, a rotating speed of the second gear set is detected by a second encoding assembly, so that output rotating speed data of the motor is obtained. Compared with the prior art, the hollow harmonic joint module has the advantages of novel design, simple structure, low cost, small volume, large torque, small heat and low cost.

Description

Technical field [0001] The present invention relates to a mechanical module technology, in particular, to a hollow harmonic joint module. Background technique [0002] The mechanical joint module needs to read the input speed of the motor, the output speed is real-time, and transmitted to the control panel for analysis and processing. The joint modules in the prior art use the two sets of hollow magnetic ring encoders to read the above data. The defect is that due to the middle of the hollow magnetic ring encoder, the null magnetic ring encoder can only be disposed at both ends of the device, resulting in a large number of volume, complicated, on the other hand, due to hollow The work of the magnetic ring encoder requires a more accurate algorithm, and the requirements for the electronic hardware part are also high, resulting in a significant high production cost. Inventive content [0003] It is an object of the present invention to achieve small volume, simple assembly, and gr...

Problems solved by technology

[0002] The mechanical joint module needs to read the input speed and output speed of the motor in real time, and transmit it to the control board for analysis and processing. The joint modules in the prior art generally use two sets of hollow magnetic ring encoders to read the above data respectively. , the defect is that: because the middle part of the hollow magnetic ring encoder is hollow, two sets of hollow magnetic ring encoders can only be installed at both ends of the equipment, resulting in a larger overall volume and more complicated assembly. On the other hand, due to the hollow The work of the magnetic ring encoder requires the design of a more accurate algorithm, and the requirements for the electronic hardware part are also relatively high, resulting in a significantly higher production cost
