Transmission device for driving segmented floatable rollers

Abstract

The invention discloses a transmission device for driving a plurality of segmented floatable rollers. The transmission device comprises a main shaft driven to rotate by a driving device, and a plurality of segmented rollers, wherein each segmented roller is in power connection with the main shaft through a set of independent belt transmission mechanism, and besides, each segmented roller is drivenby the main shaft to rotate; and each segmented roller is further arranged on the main shaft in a floating mode through one or more sets of floating mechanisms, so that each segmented roller can float up and down independently and freely. The relative positions of the axes of the segmented rollers can be continuously changed in the running state, power of all the segmented rollers is only input by one driving, and the upper limit of the rotating speed can be greatly increased. The transmission device has the advantages that: 1, one motor drives the segmented rollers with staggered axes to rotate; 2, the device can be used in high-rotating-speed occasions; 3, the cost and the operation space are saved for multi-shaft transmission; and 4, the device can be applied to compact-structure occasions.

Description

technical field [0001] The invention relates to a general mechanical mechanism, in particular to a transmission device for driving multi-stage floating rollers. Background technique [0002] In traditional mechanical design, a driving power often only independently drives a roller rotating around a fixed axis, or drives the driving power through some mechanical transmission components (such as gear transmission, chain transmission, belt transmission, universal joint coupling, etc.) It is transmitted to other rollers, but these rollers also rotate around their respective fixed axes, and the relative position and size between the axes of the rollers remains unchanged. [0003] If the structural space of the whole device is sufficient, the rollers on multiple axes will be designed to be driven independently, and the rollers and power units will be installed on their own floating devices. Then in this design, the relative position between the axes of the rollers can be changed,...

AI Technical Summary

Problems solved by technology

[0005] From the above technical background description, it can be concluded that in the case of traditional multi-roller / multi-axis drive mechanical structure design, the technical issues of "single drive power input" and "the relative position between axes can be floated" are on both sides of the contradiction. Difficult to satisfy both in one device
