AI Technical Summary

Technical Problem

Existing omni-directional wheels require additional installation space and suffer from inefficiencies in force transmission due to the need for intermediate transmission units, and they often have limited contact surface area with goods to be conveyed.

Method used

The omni-directional wheel design features rollers that are directly driven by a drive worm, eliminating the need for additional installation space and utilizing a combination of worm drive and helical teeth for efficient force transmission, with rollers having a high contact surface area and optimized material properties for better grip on goods.

Benefits of technology

The design results in compact, efficient wheels with minimal loss in force transmission and enhanced contact surface area, allowing for effective conveyance of goods.

Abstract

The present invention is directed to the rotation axis (A 12 ), a bearing drum (24) that can be rotated around the rotation axis of the bearing drum, and a rotation axis (A 12 A rotation axis (A) of the first set of rollers extends transversely to the 14.i ) mounted on a bearing drum (24) so ​​as to be rotatable about the central shaft (12), and arranged around the central shaft (12) at an angular distance from each other, at least three first set rollers each having an external thread (18) of the first set rollers with helical teeth, and a rotation axis (A 12 ) and in particular the first set of rollers (14.i) are mounted on bearing drums (24) so ​​that they can be rotated about the rotation axes of the respective second set of rollers (14.i) extending transversely to the respective first set of rollers (14.i). [Equation 1] and at least three second sets of rollers (16.i) arranged around the central shaft (12) at an angular distance from each other at JPEG2025527668000010.jpg6170, each having a second set of roller external threads (20) with helical teeth, wherein the rollers at least partially protrude above the bearing drum (24), wherein the omni-directional wheel (10) is oriented in such a way that the rotation axis (A) of the central shaft relative to the bearing drum (24) is oriented in a direction perpendicular to the rotation axis (A) of the central shaft relative to the bearing drum (24). 12 ) results in the rotational movement of the rollers about their respective axes of rotation in each case in the same direction of rotation, wherein the central shaft (12) is provided with a drive worm (22) engaging with an external thread.
