Industrial planetary gearheads IP57 series The IP57 gear box is designed to provide long life in industrial automation, industrial, scientific and process control applications that require repetitive cycling featuring high dynamics, accurate velocity or positional control. Advanced manufacturing techniques, combined with a design focused on the needs of state of the art motion control has resulted in a combination of optimised performance characteristics combined with economic prices. Key features • Planetary construction for high torque and compact dimensions • NEMA23 frame size, IP43 for NEMA17 and IP86 for NEMA35 are also available. • Suitable for use with both servo and stepper motors • Wide range of standard ratios with additional options also available • Exact gear ratios simplify calibration in positional control systems • mounting kit options to fit most motors • Standard options available from stock Construction The IP57 is based on an all metal planetary design for high strength. The materials and the treatment processes employed have been carefully selected to achieve high strength and long life. The output shaft / carrier assembly is machined from solid for optimum strength and torsional rigidity. The IP57 may be constructed with up to 4 stages to provide a gear ratio of up to 10,000:1. Unlike some multi-stage designs this is achieved using a single part annular to improve unit sealing and torsional stiffness. Each gear stage may be provided with a number of alternative ratios. IP57 series gearheads utilise precision gears to provide a controlled backlash and are therefore ideal for use in positioning systems. The design is based on the use of exact gear ratios to make the calibration of
