Abstract
The invention concerns a drive assembly for relative movement of two components of a machine tool with a drive motor and a gear arrangement with two gear trains that can be put under tension relative to each other and have output gears that mesh with opposing teeth, where each gear train has a compact gear with a high transmission ratio with at least one control element for applying tension to the two gear trains. A high positioning accuracy and torsional rigidity combined with a small size when installed are made possible according to this invention by the fact that the compact gear.
Claims10
A drive assembly for relative movement of two components of a machine tool and including a component to be driven having engaging teeth thereon, said drive assembly comprising:
- a drive motor;
- a gear arrangement having two gear trains configured to be put under tension with respect to each other;
- output gears on said gear trains configured to mesh with said teeth on said component to be driven;
- a drive shaft with a compact cycloid gear thereon having a high transmission ratio on each said gear train;
- at least one control element configured for putting tension on said two gear trains, said control element comprising releasable adapter sleeves;
- a common toothed belt engaging and driving said cycloid gears;
- and
- driving pinions frictionally securable on said drive shafts by means of said adapter sleeves.
A drive assembly for relative movement of two components of a machine tool and including a toothed rack having engaging teeth thereon, said drive assembly comprising:
- a gear arrangement having two gear trains configured to be put under tension with respect to each other;
- output gears on said gear trains configured to mesh with said teeth on said toothed rack;
- a drive shaft and a compact cycloid gear thereon having a high transmission ratio on each said gear train;
- a drive motor coupled to said cycloid gears by means of a common toothed belt;
- at least one control element configured for applying tension to said two gear trains, said control element comprising releasable adapter sleeves;
- and
- driving pinions frictionally securable on said drive shafts by means of said adapter sleeves.
