Abstract
A geartrain assembly includes a first gear, a second gear, and a third gear. A linkage connects the first gear and the second gear, and defines an assembly location of the third gear to connect the third gear to the first and second gears in a manner that minimizes a backlash in the geartrain assembly.
Claims15
A geartrain assembly, comprising:
- a first gear;
- a second gear;
- a third gear positionable between the first gear and the second gear;
- and
- a linkage including a first link member connected to the first gear and a second link member connected to the second gear, the first link member and the second link member each including at least one free end that engage one another to define a mounting location of the third gear to connect the third gear to the first gear and to the second gear, wherein:
- the first link member includes a first circular flange at one end thereof that is positioned around an idler shaft of the first gear, the first link member including a first locating member at the other end thereof opposite the first circular flange;
- the second link member includes a second circular flange at one end thereof that is positioned around an idler shaft of the second gear, the second link member includes a second locating member at the other end thereof opposite the second circular flange;
- the first and second locating members are interlocked with one another to define the mounting location for the third gear;
- and
- each of the first and second locating members includes a ring-shaped plate, and one of the first and second locating members includes a lip projecting outwardly from the ring-shaped plate thereof that is captured in the ring-shaped plate of the other of the first and second locating members.

A geartrain assembly, comprising:
- a first gear;
- a second gear;
- a third gear positionable between the first gear and the second gear;
- and
- a linkage connecting the first gear and the second gear that defines a mounting location of the third gear to connect the third gear to the first gear and to the second gear, wherein the third gear includes:
- an idler shaft including at least one hole for receiving a fastener;
- a retainer engaged to the idler shaft to retain the third gear on the idler shaft, the retainer including at least one hole for receiving the fastener;
- and
- a load plate engaged to the retainer with the fastener, wherein the at least one hole in each of the idler shaft and the retainer are over-sized relative to the fastener to allow for alignment of the third gear with respect to the mounting location.
