Description

A multi-axis transmission mechanism

technical field

The utility model relates to a multi-shaft transmission mechanical equipment, in particular to a bevel gear type multi-shaft transmission mechanism.

Background technique

In general mechanical transmission mechanisms, there is generally a single-axis input and a single-axis output, or a single-axis input and multiple-axis parallel outputs. To form a three-dimensional multi-axis output, such as two mutually perpendicular multi-axis outputs, multiple Driven by a motor, not only the manufacturing cost is high, but also the structural design is complex and huge. If a single motor drive and bevel gear transmission are used for single-axis input and three-dimensional multi-axis output, it is often impossible to flexibly and effectively adjust the orientation of multi-axis output. Control, low work efficiency, inconvenient to use.

Utility model content

The technical problem to be solved by the utility model is to provide a multi-axis transmission mechanism capable of realizing multi-directional output in space, compact in structure and flexible in control.

The technical solution adopted to solve the above technical problems: a multi-axis transmission mechanism, including a drive motor, an input shaft connected to the drive shaft of the drive motor and a casing, the input shaft extends into the casing, and a A number of side output shafts perpendicular to the input shaft are provided with bevel gears meshing with each other between the input shaft and the side output shaft. The box body is equipped with axial movement along the input shaft to connect the box body with the drive motor The drive shaft is connected to the clutch.

As an improvement of the utility model, the free end of the input shaft is provided with a main clutch and a main output shaft connected with the input shaft through the main clutch.

As another improvement of the utility model, a slider that can slide axially along the side output shaft is provided in the box, and a side bearing supporting the side output shaft is provided in the slider.

As another improvement of the utility model, a bearing is provided on the input shaft.

Beneficial effects of the utility model: by providing a clutch on the box body that can connect the box body with the drive motor or the drive shaft, when the box body is connected with the drive motor through the clutch, the box body is fixed, and the input shaft in the box body Driven by the drive shaft; when the box is connected to the drive shaft through the clutch, the box also rotates with the rotation of the drive shaft, and the axis of the side output shaft in the box rotates around the axis of the input shaft, so that through the side output The axis of the shaft is rotated and transformed to realize multi-directional output in space, and only one drive motor can drive the three-dimensional multi-axis output in space, which is compact in structure and easy to use.
