Abstract
A machine such as a material processing apparatus comprises a mechanical transmission system coupled to a mechanical load such as a crusher. An internal combustion engine is coupled to the mechanical transmission system, and at least one motor-generator is coupled to an electrical system and to the mechanical transmission system. In at least one mode of operation, the electrical system delivers electrical power to the motor-generator(s), the motor-generator(s) generating mechanical power from the electrical power and delivering the mechanical power to the mechanical transmission system to drive the mechanical load.
Claims22
A machine comprising:
- a mechanical transmission system coupled to a mechanical load;
- an internal combustion engine coupled to the mechanical transmission system;
- an electrical system;
- at least one motor-generator coupled to the electrical system and to the mechanical transmission system,
- wherein, in at least one mode of operation, said electrical system is configured to deliver electrical power to said at least one motor-generator, said at least one motor-generator being configured to generate mechanical power from said electrical power and to deliver said mechanical power to the mechanical transmission system to drive said mechanical load,
- and wherein said internal combustion engine has a rotatable output shaft that is coupled to said mechanical transmission system by a coupling that is configured to, or is configurable to, allow transmission of rotational movement from the output shaft to the transmission system and to prevent transmission of rotational movement from the transmission system to the internal combustion engine,
- and wherein, in at least one other mode of operation, said internal combustion engine is configured to deliver mechanical power to said mechanical load via said mechanical transmission system, said coupling being configured to allow transmission of rotational movement from the output shaft to the transmission system,
- and wherein in at least one of said at least one mode of operation said at least one motor-generator delivers said mechanical power to the mechanical transmission system to drive said mechanical load, said coupling being configured to prevent transmission of rotational movement from the transmission system to the internal combustion engine.
