The modular drive system also includes a brake system coupled to the second end of the motor system, and a drive gear coupled to the motor shaft, the drive gear disposed between the first end and the brake system.
Claims18
A mining machine comprising:
- a mobile base;
- a boom coupled to the mobile base;
- a dipper arm coupled to the boom;
- a transmission unit coupled to the dipper arm to move the dipper arm relative to the boom, the transmission unit including a gear case having an internal gear disposed therein;
- and
- a modular drive system releasably coupled to the gear case, the modular drive system including a motor system with a motor shaft, a first, non-drive end and a second, drive end, the motor system including a flange to releasably couple at least a portion of the modular drive system to the gear case, the modular drive system also including a brake system coupled to the motor system, and a drive gear coupled to the motor shaft, wherein the drive gear is in engagement with the internal gear of the gear case, wherein the motor shaft is a single piece motor shaft that extends entirely from the first non-drive end to the drive end and the brake system, and wherein the motor system extends from one side of the gear case.
