Drive mechanism
| Details |
Inventors: Moss, Robert E.;
Assignee: Caterpillar Tractor Co. (Peoria, IL)
Primary Examiner: Byers, Jr.; Nile G.
Assistant Examiner:
Attorney, Agent or Firm: Heming; William B.
A drive mechanism (10) has a frame (16), a driven member (14) and a first element (20) rotatable relative to the frame (18). A driving element (24) is mounted on and rotatable with the first element (20). Apparatus (34), such as a hydraulic motor (40) and pinion gear (38), engages and rotates the driving element (24). Apparatus (36), such as a brake (42) and pinion gear (44) engages and controllably blocks the driving element (24) from rotation. Final drive apparatus (66) transfers rotational motion from the first element (20) to the driven member (14), which can be, for example, a drum (14) of a compactor inside of which the drive mechanism (10) is located. The orientation of the elements of the drive mechanism (10) reduces its width which frees more area inside the space limited drum (14) and eliminates the need to mount components exteriorly to the drum (14) where they can be damaged. |

DETAILED DESCRIPTION I claim: 1.
Apparatus (10), comprising: a frame (18) including a yoke (16); a compacting drum (14) having an axis of rotation (28) and being rotatably mounted on said yoke (16); a first element (20) having an axis of rotation (26) and being associated with and rotatable relative to said frame (18) within said compacting drum (14), said axis of rotation (26) of said first element (20) being substantially the same as said axis of rotation (28) of said compacting drum (14); a driving element (30) mounted on and rotatable with said first element (20) about said axis of rotation (26) of said first element (20) within said compacting drum (14); means (34) for engaging and rotating said driving element (30), said means (34) defining an axis of rotation (46) oriented perpendicular to said axis of rotation (26) of said first element (20) and being positioned within said compacting drum (14) and carried by said frame (18); means (36) for engaging and controllably blocking from rotation said driving element (30), said means (36) defining an axis of rotation (48) oriented perpendicular to said axis of rotation (26) of said first element (20) and being positioned within said compacting drum (14) and carried by said frame (18); and final drive means (66) for receiving rotational motion from said first element (20) and rotatably driving said compacting drum (14) in response to said rotational motion, said final drive means (66) having a preselected drive ratio and being positioned within said compacting drum (14).
2.
The apparatus (10), as set forth in claim 1, wherein said driving element (30) includes a bevel gear (32) and said engaging and rotating means (34) includes a pinion gear (38) having said axis of rotation (46) of said engaging and rotating means (34) and being positioned in engagement with said bevel gear (32).
3.
The apparatus (10), as set forth in claim 1, wherein said driving element (30) includes a bevel gear (32) and said engaging and blocking means (34) includes a brake (42) and a pinion gear (44), said pinion gear (44) having said axis of rotation (48) of said engaging and blocking means (34) and being rotatably associated with said brake (42) and positioned in engagement with said bevel gear (32)
