specific Embodiment 1

[0036] An omnidirectional wheel with high precision positioning, including a hub 101, a support frame 103 is arranged on the outer circumference of the hub 101, and the support frame 103 and the hub 101 are injection molded, using high-strength hard plastic;

[0037] The supporting frame 103 is provided with a driven wheel 102, and the driven wheel 102 adopts high-strength elastic plastics to improve the frictional force of the driven wheel 102; 3 rows of driven wheels 102 are arranged on the outer circumference of the wheel hub 101; the radius of the wheel hub 101 The length of the driven wheel 102 is 8 mm, and the number of driven wheels 102 on each row of driven wheels is 24. The surface of the driven wheel 102 is provided with lines 106 along the moving direction of the driven wheel 102 .

specific Embodiment 2

[0038] Utilizing the high-precision positioning omni-directional wheels, a high-precision positioning omni-directional wheel set is further proposed, including two sets of omni-directional wheels, each set of omni-directional wheels includes 2 omni-directional wheels connected by axle 5, two sets of omni-directional wheels The steering wheel is installed in a "ten" structure;

[0039] The connection mode is as follows: comprise connecting nut 2, nut 4 and axle shaft 5, described connecting nut 2 junction is square, and junction is provided with threaded hole 3, and axle shaft 5 two ends are respectively provided with thread, and described thread and thread The hole 3 is matched, and the center of the hub 101 is provided with a square hole 105, and the square hole is matched with the joint of the connecting nut 2, and a nut 4 is arranged between the axle 5 and the hub 101 to fix the hub 101; adopt this structure , using the square hole 105 and the nut 4, the positioning and fix...

specific Embodiment 3

[0041]According to the specific embodiment 2, a high-precision omnidirectional wheel set is provided, and a high-precision mobile trolley is further provided. The mobile trolley includes a housing 6, and a high-precision cross-section is arranged under the housing 6 in the shape of a "cross". The omnidirectional wheel set A7 and the omnidirectional wheel set B8, the omnidirectional wheel set A7 and the omnidirectional wheel set B8 respectively include two identical omnidirectional wheels and the omnidirectional wheels are connected by the axle 5, the omnidirectional wheel set The wheel hubs 101 of A7 and omnidirectional wheel set B8 are different in size so that the two axles 5 are located on different horizontal planes. The omnidirectional wheel set A7 is driven by the drive motor A9, and the omnidirectional wheel set B8 is driven by the drive motor B10.

Abstract

The invention discloses a high-precision positioning omnidirectional wheel. The omnidirectional wheel comprises wheel hubs, supporting frames are arranged on the outer circumference of the wheel hubs,driven wheels are arranged on the supporting frames, the rotation direction of the driven wheels is perpendicular to the rotation direction of the wheel hubs, three rows of the driven wheels are disposed on the outer circumference of the wheel hubs, and patterns are formed in the surfaces of the driven wheels in the movement direction of the driven wheels. The omnidirectional wheel has low cost,and high-precision movement accuracy is achieved, so that the omnidirectional wheel is suitable for high-precision sports occasions.

Description

technical field [0001] The invention relates to the technical field of omnidirectional wheels, in particular to an omnidirectional wheel with high precision positioning. Background technique [0002] Omni-directional wheels are wheels that can be used to build omnidirectional mobile platforms. It is characterized in that small wheels forming a certain angle with the big wheel are distributed around the big wheel. The large wheel can be used as a driving wheel or a driven wheel, and the small wheel usually only appears as a driven wheel. When three or more omnidirectional wheels are arranged at a certain angle to each other, by controlling the speed combination between the wheels, the equipment can directly move in any direction without turning. Due to this feature, the mobile platform using omnidirectional wheels has higher movement flexibility than ordinary wheel train platforms, and can adapt to movement in a narrower space. [0003] In the case of using omni-directiona...
