Problems solved by technology

[0003] The existing drive wheels have weak bearing and frictional drive capacity and poor controllability. At the same time, an external reducer is required when in use, which increases the axial size of the power transmission system and makes the overall size of the car body not compact enough, which restricts the omnidirectional mobile robot. Promoted application of

Abstract

The invention relates to a speed reduction driving wheel and a robot with the same, and belongs to the technical field of robots. The speed reduction driving wheel comprises an omnibearing wheel body and a speed reducer, wherein the omnibearing wheel body is provided with an installation hole, and the speed reducer is arranged in the installation hole; the speed reducer comprises a first shell which is rotationally connected with the omnibearing wheel body; and the output end of the speed reducer is fixedly connected with the omnibearing wheel body. The speed reducer is arranged in the wheel body, and the omnibearing wheel body and the internal speed reducer both adopt a component-based power and free structure, so that the speed reduction driving wheel has the advantages of being easy and convenient to manufacture and assemble, compact in structure, adjustable in speed reduction ratio, high in bearing and friction driving capacity, stable in movement and good in controllability. The robot with the speed reduction driving wheel comprises a robot body and the speed reduction driving wheel. The robot is provided with the speed reduction driving wheel, is simple in structure, is convenient to assemble, can conduct translational motion and rotate simultaneously in any direction in a two-dimensional plane, and is suitable for occasions with a narrow space or requiring high maneuverability of the robot.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a deceleration drive wheel and a robot using the deceleration drive wheel. Background technique [0002] With the development of science and technology, robot technology has been improved rapidly. The omnidirectional wheeled mobile robot has three degrees of freedom in the two-dimensional plane, and can simultaneously translate and rotate in any direction. It has the ability to move in any direction without changing the posture of the vehicle body, and is very suitable for space Narrow space or occasions that require high mobility of robots, such as Automated guided vehicle (AGV) in industry, omni-directional mobile wheelchairs, etc. The main driving part of the omnidirectional wheeled mobile robot is the driving wheel, which can help the robot to move in various directions. [0003] The existing driving wheels have weak bearing and frictional driving capacity and poor controlla...
