Abstract
Abstract Electromotively driven drive unit with a planetary gearing having bevel-gear toothing and including a revolving planet gear having an inclined axis intersecting with the axis of a central gear of the planetary gearing, and a gear box for the planetary gearing having a plurality of journal shafts to which tools and devices drivable with varying rotary speeds are connectible, the improvement therein includes an internally toothed outer ring gear disposed concentrically to the central gear of the planetary gearing, the planet gear being in meshing engagement both with the teeth of the central gear and the teeth of the ring gear, the planet gear with a pin formed thereon being seated in a bearing member rotatably disposed on the axis of the central gear, the planet gear moving together with the bearing member during a whirling movement thereof about the central gear.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
156 words
Electromotively driven drive unit with a planetary gearing having bevel-gear toothing and including a revolving planet gear having an inclined axis intersecting with the axis of a central gear of the planetary gearing, and a gear box for the planetary gearing having a plurality of journal shafts to which tools and devices drivable with varying rotary speeds are connectible, the improvement therein comprising an internally toothed outer ring gear disposed concentrically to the central gear of the planetary gearing, the planet gear being in meshing engagement both with the teeth of the central gear and the teeth of said ring gear, the plane gear with a pin formed thereon being seated in a bearing member rotatably disposed on the axis of the central gear, the planet gear moving together with said bearing member during a whirling movement thereof about the central gear, whereby said bearing member rotates at a slower rotary speed than said central gear.
Claim 2
Dependent Claim
156 words
Electromotively driven drive unit with a planetary gearing having bevel-gear toothing and including a revolving planet gear having an inclined axis intersecting with the axis of a central gear of the planetary gearing, and a gear box for the planetary gearing having a plurality of journal shafts to which tools and devices drivable with varying rotary speeds are connectible, the improvement therein comprising an internally toothed outer ring gear disposed concentrically to the central gear of the planetary gearing, the planet gear being in meshing engagement both with the teeth of the central gear and the teeth of said ring gear, the plane gear with a pin formed thereon being seated in a bearing member rotatably disposed on the axis of the central gear, the planet gear moving together with said bearing member during a whirling movement thereof about the central gear, whereby said bearing member rotates at a slower rotary speed than said central gear.
Claim 3
Dependent Claim
31 words
The drive unit according to claim 1 including a hub-like appendage formed at said outer ring gear, said bearing member moving with the planet gear being mounted in said hub-like appendage.
Claim 4
Dependent Claim
35 words
The drive unit according to claim 2 wherein the pin formed on the planet gear extends through said bearing and is constructed as a coupling member for receiving thereon a shaft of a rotatable tool.
Claim 5
Dependent Claim
31 words
The drive unit according to claim 2 wherein said bearing member moving with the planet gear having entrainer elements and serving as a journal shaft with a greatly reduced rotary speed.
Claim 6
Dependent Claim
40 words
The drive unit according to claim 4 wherein said entrainer elements are located at the end face of said bearing member, said end face of said bearing member being in substantial alignment with the end face of said hub-like appendage.
Claim 7
Dependent Claim
26 words
The drive unit according to claim 2 wherein said outer ring gear with said hub-like appendage are components of the gear box surrounding the planetary gearing.
Claim 8
Dependent Claim
22 words
The drive unit according to claim 1 including a worm gear, the central gear being seated laterally coaxially at said worm gear.
Claim 9
Dependent Claim
66 words
The drive unit according to claim 7 wherein said worm gear seated at the central gear is provided with a bearing pin on a side thereof facing away from the central gear, and said worm gear is formed with a bore, on the side thereof on which the central gear is located, for receiving therein a bearing pin seated in the axis of said bearing member.
Claim 10
Dependent Claim
25 words
The drive unit according to claim 8 wherein said bearing pin of said worm gear is constructed as a journal shaft with a coupling element.
