Abstract
Provided is a roller, and more particularly, to a rotary shaft of the upper part of a rolling wheel, having an inclined surface formed along the circumference of an outer diametral surface thereof, is inserted into at least one coupling groove formed on a transfer bracket, a thrust member is provided at the upper part of the rotary shaft so as to allow a thrust load to be concentrated on the upper end of the rotary shaft or the thrust member, and a radial member is provided at the inner surface of the coupling groove and the rotary shaft positioned at the lower part of the thrust member, thereby supporting a radial load.
Claims24
A roller wherein a rotational shaft at an upper part of a rolling wheel having a slanted surface formed on a circumference of an outer diametral surface is inserted into one or more coupling grooves formed in a transfer bracket and a thrust member is installed at the upper part of the rotational shaft to allow a thrust load to concentrate on the top of the rotational shaft or the thrust member and a radial member is installed on inner surfaces of the rotational shaft and a coupling groove positioned at the lower part of the thrust member to support a radial load.
A roller wherein a rotational shaft at an upper part of a rolling wheel having a slanted surface formed on a circumference of an outer diametral surface is inserted into one or more coupling holes formed to penetrate vertically in a transfer bracket and a thrust member is installed between the bottom of a cover part coupled to an upper part of the coupling hole and the upper part of the rotational shaft to allow a thrust load to concentrate on the top of the rotational shaft or the thrust member and a radial member is installed on inner surfaces of the rotational shaft and the coupling hole positioned at the lower part of the thrust member to support a radial load.
