Rack-and-pinion drive gear reducer BMU series

planetarycoaxialpinion shaft

BMU (Plate design) Mechanical Backlash-free Specially designed with a mechanical structure eliminating the gap between the gears and racks inside the reducer and completely mitigating the backlash caused by manufacturing or installation errors when the general reducer drives the rack and pinion, and compensates or eliminates it. Driven by a single servo motor, enclosed mechanical preload system is more efficient than electrical preload system. The output flange is a plate design and easy to install or adjust. 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. Cost 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. Easy to set up Parameter setting can be easier for enclosed mechanical preload system, driven by a single servo motor, than electrical preload system. Better processing surface smooth and accuracy Backlash reducing enables improved processing surface smoothness and accuracy. 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. High Dynamics One-piece output design, special high strength the fewer teeth of pinion and smaller servo motor, achieve the low moment of inertia.
