Multi-face cascadable steering engine with position feedback center output shaft

Abstract

The invention discloses a multi-face cascadable steering engine with a position feedback center output shaft. The multi-face cascadable steering engine comprises a steering engine body and a motor. The steering engine body comprises a top shell, a gear shell and a lower shell. The lower shell is provided with a bottom outer shell connector. The motor is fixedly arranged in the gear shell. The output shaft is arranged at the central position of the gear shell, and is further provided with a reduction gear set. A rotation sensor which is in engaged linkage with the reduction gear set is further arranged in the gear shell. The top of the output shaft is connected with an output shaft connector, and connecting grooves of the same size are formed in the central position of the output shaft connector and the central position of the bottom outer shell connector. The output shaft connector can be in cascade connection with a bottom outer shell connector of the next steering engine through a quick-dismounting connecting piece, and meanwhile can be in cascade connection with the side face of the next steering engine through an angle connector. The structure is simple and geometric stability is good.

Description

technical field [0001] The invention relates to the technical field of steering gear, in particular to a multi-faceted cascadable steering gear with a central output shaft with position feedback. Background technique [0002] Existing models and servos for robots use single-sided eccentric output shafts, which are inconvenient during installation and use. The westward output shaft causes the output shaft to deviate from its geometric center, resulting in reduced accuracy, stability, and load bearing. This is especially true when multiple steering gears are cascaded and expanded. The single-sided output shaft makes the connecting surface of the steering gear very limited. It is difficult to directly connect two steering gears to each other at different angles. On the one hand, it increases the development cost and on the other hand reduces the space utilization. When multiple servos are cascaded, they must be connected in series through additional special-shaped parts, and c...

Problems solved by technology

[0002] Existing models and servos for robots use single-sided eccentric output shafts, which are inconvenient during installation and use. The westward output shaft causes the output shaft to deviate from its geometric center, resulting in reduced accuracy, stability, and load bearing. This is especially true when multiple steering gears are cascaded and expanded. The single-sided output shaft makes the connecting surface of the steering gear very limited. It is difficult to directly connect two steering gears to each other at different angles. On the one hand, it increases the development cost and on the other hand reduces the space utilization

When multiple servos are cascaded, they must be connected in series through additional special-shaped parts, and cannot be connected directly

When the steering gear is loaded, because the output deviates from the collection center, it will cause uneven distribution of weight and increase the chance of damage to the steering gear

[0003] Due to the internal mechanical structure, the output shaft of the existing steering gear has a short extension length in the steering gear and low stability
