Problems solved by technology

As another example, the patent ZL201220546988.8 proposes a heavy-duty omnidirectional mobile wheel. The hub adopts a regular prism structure, and the U-shaped bracket is fixed on the side of the hub. Positioning pin holes are processed on the type bracket, and the dimensional accuracy and position accuracy of the positioning pin holes are required to be very high. If the machining accuracy of the positioning pin holes cannot be guaranteed, the hub will affect the assembly accuracy.
In previous technical reports, the integrally formed mecanum wheel hub is usually processed by mold, and a mold can only process a wheel hub of one size; the hub body of the split mecanum wheel hub corresponds to the roller support frame, Only one type of hub can be formed

Embodiment 1

[0065] Refer to attached figure 1 to attach Figure 5 .

[0066] The technical solution adopted by the present invention to solve its technical problems is:

[0067] The first embodiment of the combined mecanum wheel hub is a two-side supported mecanum wheel hub, which includes a hub body 1 and a plurality of roller support frames, and the roller support frame adopts a roller support fork 2; figure 1 As shown, the rim 101 of the hub body 1 is provided with a plurality of connecting interfaces, and the connecting interfaces are distributed in a circular array with the axis of the hub body as the center line; the connecting interfaces include a side plane 102, a positioning groove 103 and a positioning The hole 104, the side plane 102 is set on the hub body 1 and parallel to the axis of the hub body 1, the positioning groove 103 is set in the center of the side plane 102 along the axial direction of the hub body 1, and the positioning hole 104 is set in the positioning groove ...

Embodiment 2

[0071] Refer to attached Image 6 To attach Figure 7 .

[0072] Embodiment 2 is also a two-side supported mecanum wheel hub. Embodiment 2 uses the same roller support fork as Embodiment 1. The difference from Embodiment 1 is that the overall size of the hub body in Embodiment 2 is smaller than that of Embodiment 2. The hub body of Example 1, but the size of the positioning groove and the positioning hole in the positioning groove of the hub body connection interface of the second embodiment is the same as that of the first embodiment. Like this, the connection mode of the roller support fork and the hub body of the second embodiment is the same, and the front view of assembling the second embodiment is as follows Image 6 shown. Through this combination, using the same roller support fork and hub bodies of different sizes and specifications, the Mecanum wheel hubs of different sizes and specifications are combined. Mecanum wheels of different sizes and specifications can ...

Embodiment 3

[0074] Refer to attached Figure 8 To attach Figure 12 .

[0075] Embodiment 3 is also a two-sided supported Mecanum wheel hub, which is different from Embodiment 1 in that: the hub body 1 is a regular polygon, and the side of the regular polygon is used as the side plane 102 of the connection interface. A positioning groove 103 is provided in the center of the side plane 102, such as Figure 8 shown; and a positioning block 204 is provided on the bottom plane 206 of the roller support fork 2, and the bottom surface of the positioning block 204 is square, and the extending direction of the positioning block 204 forms an oblique angle with the axis of the roller shaft hole 203 is 45 degrees, such as Figure 9 , 10 As shown; when the roller support fork 2 is connected with the hub body 1, the positioning block 204 is embedded in the positioning groove 103 on the hub body 1, and the two parallel sides of the positioning block 204 are respectively used as the positioning posi...

Abstract

The invention discloses a combined Mecanum wheel hub which comprises a hub body and a plurality of roller supporting frames. Connectors are arranged on the rim of the hub body. The connectors are distributed in a circumference array mode by using the axis of the hub body as a center line. Each connector comprises a side plane and at least one positioning groove, wherein the side plane is arranged on the hub body and is parallel to the axis of the hub body, and the positioning groove is axially formed in the side plane in the axial direction of the hub body. A roller axial hole is formed in the upper end of each roller supporting frame. A positioning block is arranged at the lower end of each roller supporting frame. An inclined included angle is formed between the extending direction of each positioning block and the axis direction of the corresponding roller axial hole. Each connector in the rim is connected with one roller supporting frame. The positioning blocks of the roller supporting frames are embedded into the positioning grooves in the rim. The roller supporting frames are fixed to the hub body. According to the combined Mecanum wheel hub, machining is facilitated due to the fact that the split combined structure is adopted, the machining precision is ensured due to the fact that the positioning embedded structure is adopted, and the roller supporting frames of different dimensions can be combined with the hub body to form Mecanum wheel hubs of different dimensions.

Description

technical field [0001] The invention relates to a combined mecanum wheel hub, which belongs to the field of omnidirectional wheel design for omnidirectional mobile platforms. Background technique [0002] The Mecanum wheel is a kind of omnidirectional wheel mechanism widely used at present. After a reasonable combination, the mobile mechanism can have the ability to move in all directions. On the rim of the mecanum wheel, there are many small free-rotating drum-shaped rollers evenly distributed, and there is a certain angle between the axis of the rollers and the axis of the hub. The processing and precision control of the hub of the mecanum wheel are relatively difficult. If the machining accuracy of the hub of the mecanum wheel cannot be guaranteed, the processed mecanum wheel will have the problems of large vibration and large local force during the rotation process. In order to ensure the processing accuracy, some mecanum wheel hubs are processed from a whole piece of ...
