Gear motors Knodler CMG This is a series of compact drive mechanisms for working with extruders and injection molding machines. Model range CMG 05 - CMG 601 It has a wide torque range from 500 to 150,000 Nm. High productivity, despite its modest dimensions, is an ideal solution not only for the plastic industry, but also for equipment in other areas (mixers, agitators, ball mills, grinders, etc.)
The CMG gear motor consists of two subassemblies, sections of the motor and gearbox. Various types of output shaft designs are available. The motor section accommodates 4th three-phase electric motor Located around the central cavity, each of their gears is mechanically connected to a common drive gear, in order to avoid transverse forces on the bearing and reduce noise levels. The total power from the shaft is distributed evenly. Such modular use of removable electric motors is very convenient to maintain, increases the service life and reliability of operation, allows you to work in emergency mode in case of failure of one unit or with reduced productivity during repair.
The gears have oblique spikes and a cylindrical shape. Available as a single-stage or two-stage transmission. Standard version with hollow output shaft. A water cooling system through a coil is integrated into all models, and a plate heat exchanger can be installed for even greater efficiency. The cooling circuit can be controlled by KTY temperature sensors, which allows you to control the flow rate of the cooler within the required limits and avoid condensation of moisture on a cooled engine. Encoders for speed control are installed optionally.
