Abstract
A shaft carrying a cutter head is bolted to the output shaft of a speed reducer gear in coaxial configuration and having a casing journalled on the shaft. The casing carries plural drive motors and the gear has a combining stage as input. The shafts are mounted in thrust and pendulum bearings in a frame and the casing is held against rotation on that frame. The output stage of the gear is a planetary gear with a spider from which extends the output shaft and a hollow shaft and in opposite directions. The casing is journalled on the shaft by bearings engaging the hollow shaft and the output shaft at opposite sides of the spider.
Claims14
Apparatus for driving a shaft at a low speed and in relation to a frame, support or the like comprising;
- a reducing gear having a casing and at least one input shaft and one output shaft, the output shaft being rigidly secured to the shaft to be driven;
- a pair of axially spaced bearings journalling the casing on the output shaft;
- a pendulum or swing bearing for journalling the interconnected output and driven shafts on the frame;
- means interconnecting the frame and the casing without preventing pendulum motion of the latter relative to the former, for inhibiting rotation of the casing relative to the frame;
- and
- a drive motor connected to the input shaft.
Apparatus for driving a shaft at a low speed and in relation to a frame, support or the like comprising:
- a reducing gear having a casing, a plurality of input shafts, and an output shaft being rigidly secured to the shaft to be driven, the gear providing for combining or rotation of the input shafts and speed reduction for low speed rotation of the output shaft;
- a plurality of motors secured to the casing and drivingly connected to the input shafts;
- a pair of bearings journalling the casing on the output shaft;
- a pendulum or swing bearing for journalling the shafts on the frame;
- and
- means interconnecting the frame and the casing without preventing pendulum notion of the latter relative to the former, for inhibiting rotation of the casing relative to the frame.
