Marine gearbox model 135A performs the duties of forward and reverse,engaging and disengaging,reduction and take the propeller trust. It can be coupled with various left-hand rotating diesel engines of 66KW/750rpm~199KW/2000rpm(90ps/750rpm~270ps/2000rpm) to form the complete power unit for marine purpose.
The said marine gearbox has the following features:
1. Using the torsional shaft transmission with two sets of clutches mounted on its rear end. The clutch is smooth in engagement as well as conveninet in disassembly and reassembly for maintenance and repair.
2. Identical in forward and reverse gear reduction ratios,both of which can transmit the full power. So it's suitable for boats and ships equipped with single-engine and single-propeler or multi-engines and multi-propellers.
