Detailed Description
The double-support type omni-directional wheel is composed of a hub 1, a mounting blade 2, a mounting rotating pin 3, a support side roller 4 and a support main roller 5 (see the attached figures 3, 4 and 5 in the specification).
The middle part of the hub 1 is provided with a mounting hole; a plurality of lightening holes 11 are uniformly formed in the periphery of the mounting hole (see the attached figure 9 in the specification); the circumferential surface of the hub 1 is provided with a positioning groove 12.
A plurality of assembling blade groups are welded on the circumferential surface of the hub 1 through positioning grooves 12; the assembly blade group is composed of two assembly blades 2 (see the description and the attached figures 4 and 5).
The assembling blades 2 in the same group are oppositely provided with assembling holes 6 (see the description and the attached figures 7 and 8); the mounting rotating pin 3 is movably mounted in the mounting blade group through a mounting hole 6 of the mounting blade 2 and a bearing 7 (see the attached figure 5 in the specification).
An intermediate sleeve 8 is fixedly arranged on the mounting rotating pin 3 between the assembling blades 2 in a pin fixing mode, and a supporting main roller 5 is fixedly arranged on the intermediate sleeve 8 in a bonding or spline connection mode. When the supporting main roller 5 is stressed, the supporting main roller can drive the middle sleeve 8 and the mounting rotating pin 3 to synchronously rotate.
an installation sleeve 10 is fixedly arranged on the installation rotating pin 3 at one side of the assembly blade 2 through a locking nut 9; the assembling sleeve 10 is fixedly provided with a supporting side roller 4 in a bonding or spline connection mode. The supporting main roller 5 and the supporting side roller 4 are made of wear-resistant plastic materials.
The supporting main roller 5 and the supporting side roller 4 form a spindle shape (see the attached figures 4 and 5 in the specification); the ratio of the length of the supporting main roller 5 to the length of the supporting side roller 4 is 2: 1; the purpose of setting the proportional relationship is as follows: so that when the omni wheel normally moves straight or stops, the omni wheel supports the main roller 5 as a main pressure bearing surface; when the omnidirectional wheel turns, the supporting side roller 4 serves as a main pressure surface, so that the purpose that the supporting side roller 4 and the supporting main roller 5 are stressed in a staggered mode is achieved, and the purpose that the service lives of the supporting side roller 4 and the supporting main roller 5 are prolonged is achieved. In addition, after the three-section type supporting device is arranged into a three-section type, even if a single supporting side roller 4 or a supporting main roller 5 is abraded, when the abrasion part needs to be replaced, the abrasion part only needs to be replaced, and therefore the purpose of saving the maintenance cost can be achieved.
the length direction of the assembling blade 2 is consistent with the normal direction of the hub 1; the included angle between the installation rotating pin 3 and the central line of the hub 1 is 45 degrees.
Compared with the traditional omni wheel, the double-support omni wheel is assembled by a main support roller 5 and an edge support roller 4 through two groups of assembling blades 2 and mounting rotating pins 3; after the arrangement, the assembly blade groups can be separated independently, so that the main supporting roller 5 and the side supporting rollers 4 on each assembly blade group can be replaced independently, and the problem of complex maintenance caused by the fact that the existing omnidirectional wheel pair needs to be completely disassembled when a single roller is replaced is solved; in addition, the omni wheel is assembled by installing the rotating pin 3 through the two groups of assembling blades 2, the stress of the rotating pin 3 is more reasonable and reliable, the omni wheel runs stably, and the service life of the omni wheel is longer compared with that of the existing single-support omni wheel, so that the use requirements of people are met.
