Abstract

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.

Claims (16)

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.

2. The industrial hybrid engine according to claim 1 , wherein the electric motor is disposed on one side of the first support bracket in a direction protruding from the engine body, and the tension mechanism is disposed on the other side.

3. The industrial hybrid engine according to claim 2 , wherein the first support bracket is attached to the exhaust manifold disposed side of the engine body.

4. The industrial hybrid engine according to claim 3 , wherein the first support bracket is attached to a transmission case mounted on one end of a cylinder block.

5. The industrial hybrid engine according to claim 2 , wherein the first support bracket is attached to a transmission case mounted on one end of a cylinder block.

6. The industrial hybrid engine according to claim 1 , wherein the first support bracket is attached to the exhaust manifold disposed side of the engine body.

7. The industrial hybrid engine according to claim 6 , wherein the first support bracket is attached to a transmission case mounted on one end of a cylinder block.

8. The industrial hybrid engine according to claim 1 , wherein the first support bracket is attached to a transmission case mounted on one end of a cylinder block.

9. The industrial hybrid engine of claim 1 , wherein the tension body is configured to energize the swing arm around the shaft center while supported by the first support bracket.

10. The industrial hybrid engine of claim 9 , wherein the electric motor and the cylinder head are positioned at an equal height.
