Embodiment Construction

[0017] An embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] figure 1 It is a structural schematic diagram of an existing Swiss wheel. Such as figure 1 As shown, the existing Swiss wheel includes a driven wheel 1, a hub 2 and an end cover 3. The driven wheel 1 is fixed on the hub 2 by rivets between the hub 2 and the end cover 3 . figure 1 The rivets of the middle Swiss wheel cannot be disassembled, so the driven wheel 1 is not easy to replace.

[0019] figure 2 It is a three-dimensional schematic diagram and an exploded view of a specific embodiment of the present invention, wherein figure 2 (b) by figure 2 (a) Obtained by explosion along the axis of hub 2. Such as figure 2 As shown, the omnidirectional wheel includes 16 driven wheels 1, a hub 2 and an end cover 3. The 16 driven wheels 1 are distributed on two circumferential planes, arranged in a staggered manner, and the centers of the tw...

Abstract

The invention provides an omnidirectional wheel which comprises a plurality of driven wheels, a wheel hub and two end covers, wherein each driven wheel comprises a support shaft, a support sleeve, a rubber sleeve, two linings and two bearings; the support shaft sequentially passes through one lining, one bearing, the support sleeve, the other bearing and the other lining; the two bearings are clamped at two ends of the support sleeve, so that the support sleeve can not generate displacement in radial and axial directions relative to the support shaft; the outer ring of each bearing can rotate relative to the support shaft, and the inner ring of each bearing is relatively fixed with the support shaft; and one side of each lining is clamped in the wheel hub, and the other side of each lining clamps the inner ring of each bearing. The omnidirectional wheel provided by the invention overcomes the defects that the existing omnidirectional wheel is poor in motion control precision and the driven wheels stall and are not convenient to disassemble and assemble.

Description

technical field [0001] The invention relates to an omnidirectional wheel, which can be applied to an omnidirectional moving mechanism to realize the movement of the omnidirectional moving mechanism in a two-dimensional plane at any pose. Background technique [0002] The omnidirectional mobile mechanism is a mobile platform widely used in warehousing, transportation, teaching and scientific research. The omnidirectional wheels as its components are independently driven in multiple directions. Arbitrary poses (straight, horizontal, oblique, rotation, and various continuous curves) move in a two-dimensional plane. There are two types of existing omnidirectional wheels, one is the Mecanum wheel, which is composed of a hub and a number of rollers. Generally, the design axis of the hub and the design axis of the rollers are at 45°, and the design axis of the outer contour of the rollers is in line with that of the rollers. The theoretical circumferences of the wheels coincide an...
