Universal wheel mechanism with double parallel rotating shafts

Abstract

The invention discloses a universal wheel mechanism with double parallel rotating shafts, which comprises a wheel seat, a wheel body, a wheel support and a transition piece. The wheel bracket is mounted on the wheel seat through a transition piece, the wheel bracket and the transition piece form a first rotating pair, the transition piece and the wheel seat form a second rotating pair, the rotating axes of the first rotating pair and the second rotating pair are parallel to each other and the distance between the rotating axes of the first rotating pair and the second rotating pair is the first eccentricity. The wheel body is rotatably mounted on the wheel bracket and is eccentrically mounted with respect to the wheel bracket, the rotation center of the wheel body is offset from the rotation axis of the first rotating pair, and the offset distance is a second eccentricity; The first eccentricity is equal to the second eccentricity. By arranging a transition piece between the wheel support and the wheel seat, the universal wheel mechanism with the double parallel rotating shafts of the invention can ensure that the swing of the wheel support does not cause the left-right swing vibration of the device itself in the reverse movement process of the equipment mounted with the universal wheel mechanism, and can effectively guarantee the traveling stability and the traveling precisionof the device.

Description

technical field [0001] The invention relates to the field of casters, in particular to a universal wheel mechanism with double parallel rotating shafts. Background technique [0002] Universal wheels are often used in industrial equipment and living facilities. Generally, in order to make the equipment turn conveniently, the universal wheels used are all eccentric universal wheels. There is a common problem in the application of eccentric universal wheels to equipment, that is, the equipment originally faces If the movement stops in one direction and then moves in the opposite direction, at this time, because the wheel body and the wheel bracket of the eccentric universal wheel cannot maintain stability, the wheel bracket will rotate relative to the equipment body and swing back. The contact part of the ground will deviate from the movement direction of the equipment. Due to the friction between the wheel body and the ground, a component force perpendicular to the movement d...
