Multi-faceted cascadable servos with center-out axis for position feedback

Abstract

The invention discloses a multi-faceted cascadable steering gear with a center output shaft with position feedback, comprising a steering gear main body and a motor, the steering gear main body includes a top shell, a gear shell and a lower shell, and the lower shell is provided with a bottom shell The connection port, the motor is set and fixed in the gear housing, the center of the gear housing is provided with an output shaft, the output shaft is provided with a reduction gear set, and the gear housing is also provided with a rotation sensor interlocking with the reduction gear set, the top of the output shaft is connected to There is an output shaft connector, and the center of the output shaft connector and the connection port of the bottom shell is provided with a connection groove of the same size. It can be cascaded with the side of the next steering gear through an angle connector, with simple structure and good geometric stability.

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
