Conical-cylindrical reducers Watt Drive
The compactness and optimized structure of the housing of cylindrical-conical gearboxes distinguishes them by their versatility, which is a ready-made solution for various installation and application options. The unique position of the engine ensures an almost flat and easy installation on the machine unit.
The various designs of the output shaft, flange and double seals developed by Watt Drive make these gearboxes convenient and very reliable. The dimensions of the shafts and flanges are similar for cylinder-worm drives.the same company. In this case, the torque and price will be lower and perhaps this option will suit you.
At low speeds of the electric motor, for its safety, we recommend purchasing Forced cooling of the electric motor, it will not allow your motor to overheat and burn out.
