この発明は設置スペースを減らすことができるようにし
た推力駆動装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical field to which the invention pertains] This invention relates to a thrust drive device that can reduce installation space.
推力駆動装置の従来例を第１図および第２図にもとづい
て説明する。これらの図は電動シリンダを示し、ラック
付シリンダ１がピニオン２を介して減速機付電動機８で
直線的に前進および後退駆動されるようになっている。A conventional example of a thrust drive device will be explained based on FIGS. 1 and 2. These figures show an electric cylinder, in which a cylinder 1 with a rack is linearly driven forward and backward by a motor 8 with a reduction gear via a pinion 2.
このような構造ではシリンダ１が後退時にストロークと
同一長さだけ電動機Ｂの後方に突出するので設置スペー
スが増すという欠点があった。This structure has the disadvantage that the cylinder 1 protrudes to the rear of the electric motor B by the same length as the stroke when retracting, which increases the installation space.
この発明は前記の欠点を除去するために、後退用スペー

掛けて直線運動させることができるようになっている。FIGS. 8 and 4 show embodiments of this invention,
Components designated by the same reference numerals as in FIG. 1 are the same parts. In these figures, a sprocket 82 is fitted to the output shaft 8a of the art motor 8, and a long thin plate-like elastic member 81 wound around the reel 3B in the shape of a tape measure can be hooked on the sprocket 82 and caused to move linearly. It looks like this.

のない推力伝達を行うことができるようになっている。The bullet member 81 has an arcuate free cross section with high mechanical strength, and has protruding teeth 8 provided on the outer periphery of the sprocket 82.
A large number of engaging holes (engaging portions) 81a that engage with 2B are provided at equal intervals. This elastic member 81 has one end connected to the reel 8'.
8, and a coupling 84 is attached to the other end as shown in FIG. The outer periphery of the sprocket 82 has an arcuate cross-sectional shape along the elastic member 81. A guide roller (guide portion) 85 is provided on the outer periphery of the sprocket 82 and has a guide surface with an arcuate cross section along the elastic member 81 on the outer periphery. Insert the elastic member 81 into the engagement hole 81 & tooth portion 82 of the sprocket 82.
By hooking the & and sending it out or rewinding it, thrust can be transmitted without slipping.
前記リール８８とスプロケット８２の間には弓形断面の
弾性部材８１を弾性限界内で平板状に変形させる一対の
ローラ８６が設けられている。A pair of rollers 86 are provided between the reel 88 and the sprocket 82 to deform the elastic member 81 having an arcuate cross section into a flat plate shape within the elastic limit.
