Shifting of transmission power ratio and power generation for mixer or shredder without power interruption

A method for delivery of power from a power source to a mixing tank in a mixer or shredder in which power from the power source varies depending on external loads imposed on the power source generated by loading of mixing or shredding materials in the mixing tank, the method comprising:

• (a) providing input power to an input shaft of a transmission;
• (b) providing output power to an output shaft on the transmission for delivery of power to a rotatable member at the mixing tank;
• and
• (c) converting the power from the input shaft to power output external loads and concomitantly altering the speed of movement thereof to counter external loads on the power source,

An apparatus for delivery of power from a power source to a mixing tank in a mixer or shredder in which power from the power source varies depending on external loads imposed on the power source generated by loading of mixing or shredding materials in the mixing tank, the transmission comprising:

• (a) a motor;
• (b) a drive train connected to the motor, wherein the drive train includes a main transmission shaft, for delivery of power from the motor to the mixing tank;
• (c) a drive huh, and a drive gear mounted on the drive huh to rotate with rotation of the transmission main shaft from the motor;
• (d) a power takeoff shaft, connected in the motor, which includes an input shaft;
• (e) an oil pump, including a main pressure regulator valve, for regulation of main pressure, and a lube pressure regulator valve, for regulation of lube pressure;
• and
• (f) an oil pump gearing system, which generates opposite rotation of the power take off shaft from the motor, which includes a main pressure gear, connected to the main pressure regulator valve, and a lube pressure gear, connected to the lube pressure regulator valve, wherein the main pressure gear and the lube pressure gear are rotatably mounted in relation to and interengageable with, the drive gear, and connected to the input shaft of the power take off shaft, for rotation of the power takeoff shaft in the direction.
