Industry Learning | Core Components of Humanoid Robots! One article learning about gearboxes
The reducer is like a "variable speed gear" in machinery, serving as a "middleman" connecting the motor and robot joints.
Its main task is to transform the high-speed but low force rotation of the motor into low-speed but powerful movements, while making the robot move more accurately.
For example, when tightening screws on industrial robots, using the high speed of the motor directly may break the screws, and the reducer is like stepping on the "brake" of the motor, making the force control more delicate.
Gearboxes are mainly divided into three categories: harmonic, RV, and planetary.
Harmonic reducers are like "soft springs" that rely on the deformation of flexible gears for transmission. They have small size and high precision, making them suitable for places like robot wrists that require flexible and precise operation.
RV reducers are like "tough guys", with complex structures but capable of carrying heavy objects, often used in robot arms or thighs that require strong support.
Planetary reducers are like "economical" models, with simple structures and low costs, suitable for scenarios that do not require high precision, such as conveyor belts in automated production lines.
The composition of the reducer industry chain can be divided into three parts: upstream, midstream, and downstream.
Upstream mainly involves raw materials and processing equipment.
Raw materials include engineering plastics (such as Peek materials), metal materials, and lubricating oils (such as synergistic oils and Derunbao oils).
The processing equipment mainly consists of gear processing equipment, such as Liebherr gear grinding machines, Casifugi gear hobbing machines, and Leshauer gear grinding machines.
The midstream segment focuses on the production of precision reducers, including harmonic reducers, cycloidal reducers, precision planetary reducers, and precision worm gear reducers.
The downstream application fields are extensive, mainly including industrial robots, precision machine tools, non-standard automation, semiconductor equipment, and medical equipment.
Overall, the upstream and downstream links of the reducer industry chain are closely connected, from the supply of raw materials and processing equipment, to the manufacturing of precision reducers, and to the widespread application in various fields, forming a complete and complex industrial ecosystem.
