Rack-and-pinion drive gear reducer DMU series

planetarycoaxialpinion shaft

DMU series could reach zero-backlash with high accuracy Characteristic: 1. Enclosed Gearbox Specially designed machinery is able to eliminate clearance from the gearbox inner and from between pinions and racks. This completely supplements and clears up the backlash of manufacture or/and installation while gearboxes drive both pinions and racks. Saving Mechanical preload system, driven by a single servo motor, can reach the goal of Electrical preload system, save controller and driver cost. Backlash eliminating enables processing tool tracks stable, which prolongs tool life. 2. Easy to set up Parameter setting can be easier for enclosed mechanical preload system, driven by a single servo motor, than electrical preload system. 3. Backlash reducing enables improved processing surface smoothness and accuracy. 4. Huge Torsional Rigidity For the well-designed structure and high duty material of taper roller bearing, the output shaft of the reducer can bear the huge axial and radial load, which could be wide application. 5. Precise Positioning Precision gear grinding tooth surface smooth, precise tooth. For an excellent design, high accuracy and low moments of inertia. 6. Efficiency >93%
