US 2016/0107522 A1 · Modular Power Take-Off Assembly

Abstract

A modular PTO assembly and an engine system comprising a modular PTO assembly are disclosed. The modular PTO assembly is configured to be mounted and secured to a crankcase of an engine, and includes a front cover positioned on a base plate so as to define a housing. The modular PTO assembly also comprises a power input sprocket mechanically coupled to a power output sprocket via a chain. The power input sprocket is coupled to a nose of a crankshaft and is configured to rotate at an approximately same speed as the crankshaft. The power output sprocket is configured to be coupled to a shaft of an auxiliary component and to rotate at an approximately same speed as the shaft, thereby transferring power from the engine to the auxiliary component.

Dependent claims

A modular power take-off assembly configured to be mounted and secured to a crankcase of an engine, the modular power take-off assembly comprising:

a front cover and a base plate, wherein the front cover is positioned on the base plate so as to define a housing that is separated from the crankcase;
a power input sprocket that is configured to be coupled to a nose of a crankshaft through a first bore through the housing and is configured to rotate at an approximately same speed as the crankshaft;
a power output sprocket configured to be coupled to a shaft of an auxiliary component through a second bore through the housing and is configured to rotate at an approximately same speed as the shaft;
and
a chain that mechanically couples the power input sprocket to the power output sprocket, wherein the power input sprocket, the power output sprocket, and the chain are located inside the housing.

An engine system comprising:

an engine comprising a crankcase, a crankshaft, and a timing sprocket, wherein the timing sprocket is mounted on a nose of the crankshaft, the nose of the crankshaft being at a forward end of the engine;
and
a modular power take-off assembly mounted to the forward end of the engine, the modular power take-off assembly comprising:
a front cover and a base plate, wherein the front cover is positioned on the base plate so as to define a housing that is separated from the crankcase:
a power input sprocket coupled to the timing sprocket through a first bore in the housing and configured to rotate at a substantially equivalent speed as the crankshaft;
a power output sprocket configured to be coupled to a shaft of an auxiliary component and to rotate an approximately same speed as the shaft;
and
a chain that mechanically couples the power input sprocket to the power output sprocket, wherein the power input sprocket, the power output sprocket, and the chain are located inside the housing.
