Abstract
The disclosure provides a wheel for an omnidirectional moving device which takes fewer man-hours for manufacturing, and a manufacturing method of the wheel for an omnidirectional moving device which takes fewer man-hours. The wheel includes an annular core body 36; a plurality of bearings 75 each including an inner ring 76 and an outer ring 77 relatively rotatable with respect to the inner ring, and the inner ring being fixed to an outer peripheral surface of the core body; and a plurality of rollers 37 each fixed to the outer ring and rotatably supported by the core body via the bearing. The inner ring is tightened and fitted to the core body.
Claims20
A wheel, comprising:
- an annular core body;
- a plurality of bearings each comprising an inner ring and an outer ring relatively rotatable with respect to at least one of the plurality of the inner rings, wherein at least one of the plurality of the inner rings is fixed to an outer peripheral surface of the core body;
- and
- a plurality of rollers each fixed to at least one of the plurality of the outer rings and rotatably supported by the core body through at least one of the plurality of the bearings,
- wherein at least one of the plurality of the inner rings is fitted to the core body,
- wherein at least one of the plurality of the inner rings abuts on the core body.
A wheel, comprising:
- an annular core body;
- a plurality of bearings each comprising an inner ring and an outer ring relatively rotatable with respect to at least one of the plurality of the inner rings, wherein at least one of the plurality of the inner rings is fixed to an outer peripheral surface of the core body;
- a plurality of rollers each fixed to at least one of the plurality of the outer rings and rotatably supported by the core body through at least one of the plurality of the bearings;
- and
- collar members fixed to the core body on both sides of at least one of the plurality of the inner rings in an axial direction of at least one of the plurality of the rollers and having a circular inner hole smaller than an inner diameter of at least one of the plurality of the inner rings,
- wherein the collar members are fitted to the core body,
- wherein at least one of the plurality of the inner rings abuts on the core body.
A manufacturing method of a wheel which comprises an annular core body, a plurality of bearings each comprising an inner ring fixed to the core body and an outer ring relatively rotatable with respect to at least one of the plurality of the inner rings, and a plurality of rollers each fixed to at least one of the plurality of the outer rings to be rotatably supported by the core body through at least one of the plurality of the bearings, the manufacturing method of the wheel comprising:
- a mounting step of mounting the plurality of the bearings to which the plurality of the rollers are fixed on a pipe material;
- a positioning step of positioning the the plurality of bearings;
- a pressurizing step of fixing at least one of the plurality of the inner rings to the pipe material by injecting a fluid into an inner hole of the pipe material and pressurizing the pipe material;
- and
- a molding step of forming the core body from the pipe material to which at least one of the plurality of the inner rings is fixed.
A manufacturing method of a wheel which comprises an annular core body, a plurality of bearings each comprising an inner ring fixed to the core body and an outer ring relatively rotatable with respect to at least one of the plurality of the inner rings, and a plurality of rollers each fixed to at least one of the plurality of the outer rings to be rotatably supported by the core body through at least one of the plurality of the bearings, the manufacturing method of the wheel comprising:
- a mounting step of respectively mounting at least one of the plurality of the bearings to which at least one of the plurality of the rollers is fixed and two collar members having an inner diameter smaller than an inner diameter of at least one of the plurality of the inner rings on a pipe material so that the collar members face each other through at least one of the plurality of the bearings;
- a positioning step of positioning the collar members to be close to at least one of the plurality of the inner rings;
- a pressurizing step of fixing the collar members to the pipe material by injecting a fluid into an inner hole of the pipe material and pressurizing the pipe material;
- and
- a molding step of forming the core body from the pipe material to which at least one of the plurality of the inner rings is fixed.
