COMPLIANT GEAR ASSEMBLY AND WORK MACHINE USING SAME

摘要

A compliant gear assembly (20, 120, 220, 420) includes a gear ring (22, 122, 222, 422) positioned about a hub (26, 129) and configured to translate responsive to a torque on the gear assembly (20, 120, 220, 420), and biased toward co-axial alignment with the hub (26, 129) via at least one actuator (31, 52, 152, 252, 452). A method of managing loads on an idler gear (20, 120, 220, 420) in the gear train (11, 41 1) is still further provided including translating the gear ring (22, 122, 222, 422) responsive to the torque on the idler gear (20, 120, 220, 420). A work machine (8) includes an engine (10, 410) having a housing (12, 412) and a geartrain (11, 411) mounted thereon, the geartrain (11, 411) including a crank gear (14, 418), a cam gear (19, 419) and a compliant idler gear assembly (20, 120, 220, 420).
