Semi-embedded Mecanum wheel structure

Abstract

The invention discloses a semi-embedded Mecanum wheel structure, and belongs to a Mecanum wheel structure. The semi-embedded Mecanum wheel structure comprises a hub, a motor and a driven wheel mounted on the hub and further comprises a supporting barrel, the supporting barrel is sleeved with the hub, a first bearing and a second bearing are arranged between the hub and the supporting barrel, and the hub is connected with a first bearing cover plate and a second bearing cover plate. The supporting barrel is sleeved with the first bearing cover plate, the first bearing cover plate is used for fixing the outer ring of the first bearing, and the second bearing cover plate is used for fixing the outer ring of the second bearing. A step is arranged on the supporting barrel, the step is blocked by the inner ring of the first bearing, the supporting barrel is connected with a motor cover plate, and the motor cover plate is pressed on the outer side of the inner ring of the second bearing. A speed reducer is arranged in an inner cavity of the supporting barrel, the motor is mounted on the speed reducer, a motor shaft of the motor is connected with an input shaft of the speed reducer, a hoop is connected to an output shaft of the speed reducer, and the hoop is connected with the second bearing cover plate. According to the semi-embedded Mecanum wheel structure, the internal space of the hub is fully utilized, and transmission precision and rigidity are improved.

Description

[0001] Technical field: [0002] The invention relates to a mecanum wheel structure, in particular to a semi-embedded mecanum wheel structure. [0003] Background technique: [0004] Mecanum wheel is an important way to realize the all-round mobile platform. Through the particularity of its own structure, the driving wheel is equipped with multiple driven wheels with a certain angle to the axial direction, so that during the movement, the Mecanum wheel can The wheels can obtain oblique friction, and through the combination of multiple Mecanum wheels, the omnidirectional movement of the mobile platform can be realized, including translation at any angle and rotation around any point, which makes it highly maneuverable Sex, especially in a small space to complete complex movements. [0005] In the usual mecanum wheel structure, the driven wheel is installed on the periphery of the hub of the mecanum wheel, the rest of the hub is the supporting structure of the hubs on both sides...
