Zhaowei Machinery & Electronics Co., Ltd.

Robot Joint Gearbox

ZHAOWEI uses modern technology to provide a variety of gear motor specifications of robot joints, ranging from 3.4mm, to 45mm, to meet their respective requirements. Through years of R&D and design, combined with the market demand for robot joints, ZHAOWEI has optimized gear design, manufacturing accuracy, and gear backlash. Through the interaction between communication and rapid response, the DC gear motor drives the robot joints. This requires a larger power-to-weight ratio and torque-to-inertia ratio, higher starting torque, low inertia, and wide & smooth speed adjustable range. The robotic end-effector (gripper), specifically, should utilize a joint motor of compact size, light weight, and high short-period overload capacity.

The DC gear motor of the robot joint has 2-stage, 3-stage, and 4-stage transmission changes. The reduction ratio, input speed and torque of the gearbox can be adjusted according to the design requirements of the robot motor. In addition, our robots’ gear motors have low voltage, low power, low speed, low-noise, long sevice life, are small, with high torque. This meets the transmission requirements of six-degree-of-freedom control for actions better. The transmission efficiency improves, and noise reduces. 

When designing the robot joint gear mold, the gear displacement figures, and the planetary gear tooth interference check optimizes to improve joint motor efficiency. This also reduces the noise produced, so that the robot joint can move more flexibly.

ZHAOWEI conducts R&D on abrasion-proof material technology, processing optimization techniques, lubrication technology, packaging technique, life testing technology, and transmission mechanism. ZHAOWEI develops and manufactures micro robot joint gearboxes, to improve the performance of intelligent robots. This includes perception and identification, mechanism and transmission, control and interaction, etc. The precision robots adopt gear motors with planetary gearhead, with customizable parameters (diameter: 3.4mm-38mm, power: 0.01-40W, output speed: 5-2000rmp, gear ratio: 5-1500, output torque: 1.0 The voltage, speed and torque of the robot joint gearbox are generally determined by the clients’ requirements.

With the concept of “Industry 4.0” proposed by Germany, and the development of 5G technology, the manufacturing industry has gradually shifted from a traditional labor-intensive industry, to a technology-intensive industry. Intelligent manufacturing sees a promising future, which also affects the development of robotics. Since the requirements of robot transmission technology are more sophisticated, ZHAOWEI is able to provide customizable services according to the needs of different clients.
