Abstract

본 발명은 갠트리형 로봇이나 크레인 등의 양단구동시스템에 관한 것으로, 특히 양단구동시스템에서 이격거리가 큰 양단구동부로의 동력전달시 동력전달부의 자체하중에 의한 처침을 방지하고 백래쉬보정을 통한 구동정밀도의 향상을 기한 원거리의 양단구동부 구동장치에 관한 것이다.The present invention relates to a two-end drive system, such as a gantry-type robot or crane, in particular, to prevent the drooping by the self-load of the power transmission unit during power transfer from the two-end drive system to the large-distance drive unit with a large separation distance and drive accuracy through backlash compensation It relates to a drive device of both ends of the long distance to improve the.

본 장치는 지지부와 구동부를 따로 둠으로써 회전구동시 구동계에 부하를 주지않아 구동부의 원활한 구동으로 운행의 안정화를 꾀할 수 있다, 뿐만 아니라, 레일간에 따른 구동부의 거리조정이 가능해 레일상에 설치가 용이하고, 설치시의 위치정밀도도 향상할 수 있는 잇점을 갖는다. 특히, 레일과 구동시스템이 치합되어 구동되므로 미끄러짐 등을 방지하여 정지정밀도가 뛰어는 효과도 가지고 있다.This device can be installed on the rails because the support part and the drive part are separated so that the driving can be stabilized by the smooth drive of the drive without applying load to the drive system during rotational drive. In addition, the positional accuracy at the time of installation is also improved. In particular, since the rail and the driving system are driven together, the rails and the driving system are prevented from slipping, and thus the stopping precision is excellent.

Claims

A drive system of a wide-end drive system having a wide interval spaced on a rail by transmitting driving force of a drive motor to a drive unit configured at both ends, the drive system comprising: a drive shaft extended to both sides of the drive motor; A length adjusting means connected to the drive shaft to be bent at a predetermined angle to transmit rotational force and to change length in an axial direction; Drive direction converting means for converting and outputting the direction of the driving force in a substantially perpendicular driving direction by receiving the driving force of the drive shaft by the length adjusting means; A gear drive for driving the drive system on the rail by receiving power from the drive direction converting means; And support wheels fixed to both ends of the drive system and mounted on the rail to support and rotate the load of the drive system.

According to claim 1, wherein the driving direction converting means is a case fixed to both ends of the body, the first gear and the first gear to be rotated by the rotational force from the length adjusting means fixed to the case rotatably in the same direction as the drive shaft, And a second gear for driving the gear drive body by being engaged down substantially perpendicularly to the gear.

3. The pinion according to any one of claims 1 and 2, wherein the gear drive member is fitted with a pinion mounted on an end of the shaft formed in the second gear, and is engaged with the pinion gear and is fixed to a side of the rail. Both end drive unit of the distant drive, characterized in that consisting of a rack gear to guide the rotation of the gear.

The device of claim 1 or 2, wherein the length adjusting means connects the drive shaft and the input shaft of the first gear and is a universal joint of spline coupling that is contracted and expanded in the longitudinal direction. .
