Abstract

The invention provides a steering engine. The steering engine comprises a shell, the shell is internally provided with a motor and a gear transmission system side by side, the motor is in drive connection with the gear transmission system, the gear transmission system comprises a first fixed star tooth ring, an eccentric wheel, a stepped pulley, a second fixed star tooth ring and a connection shaft, and the connection shaft penetrates through centre holes of the first fixed star tooth ring, the eccentric wheel, the stepped pulley and the second fixed star tooth ring in sequence. According to the steering engine, a first planetary wheel and a second planetary wheel are connected together in a butted manner, compared with a traditional connection structure, a coupler is omitted, the steppedpulley is further connected utilizing the eccentric wheel, the first planetary wheel and the second planetary wheel on the stepped pulley are made to be engaged with the first fixed star tooth ring and the second fixed star tooth ring correspondingly, this connection manner makes connection be more compact, reduction of the volume of the steering engine is facilitated, and a manner of fixed star tooth and planetary tooth engaging is adopted, a large deceleration ratio can be realized, a large tooth portion can be adopted, machining is conveniently performed, and the tooth number difference onthe stepped pulley can also be reduced.

Description

technical field [0001] The invention relates to the technical field of robot driving devices, in particular to a steering gear. Background technique [0002] A robot has many joints, and each joint is called a degree of freedom. A general body has more than a dozen degrees of freedom, so that the flexibility of movement can be guaranteed. On the robot body, we usually use the servo as the connecting part of each joint. It can complete the positioning and movement of each joint. [0003] In the prior art, there is a complex reduction gear device in the steering gear, which leads to a complicated internal structure of the steering gear and a low reduction ratio. Contents of the invention [0004] For this reason, an object of the present invention is to propose a steering gear with simple structure, convenient processing, and relatively large deceleration. [0005] The invention provides a steering gear, comprising: a casing, in which a motor and a gear transmission syst...
