Industrial hybrid engine
In an industrial hybrid engine, an endless rotary band wound around a drive pulley of a crankshaft and a motor pulley of an electric motor for power is provided. The electric motor is attached to an engine body by using a support bracket. A tension mechanism is supported by the support bracket, the tension mechanism tensioning the endless rotary band in a direction in which the endless rotary band is stretched. A second support bracket that supports the electric motor separately from the support bracket is provided.
1. An industrial hybrid engine comprising:
an engine body,
a cylinder head,
an endless rotary band wound around a drive pulley of a crankshaft and a motor pulley of an electric motor for power,
a first support bracket attached to the engine body, a lower side of the electric motor being attached at a fixed position on the engine body via the first support bracket,
a separate, second support bracket supported only by the cylinder head, an upper side of the electric motor being attached to the second support bracket, wherein the second support bracket includes a front attachment portion, a rear attachment portion, and an action piece protruding rearward from the rear attachment portion, the front attachment portion being bolted to a front surface of the cylinder head and the rear attachment portion being bolted to a left side surface of the cylinder head, and
a tension mechanism supported by the first support bracket, the tension mechanism including a tension pulley, a swing arm pivotally supporting the tension pulley proximate a tip of the swing arm and a tension body configured to energize the swing arm around a shaft center, the tension mechanism being configured to tension the endless rotary band in a direction in which the endless rotary band is stretched.
