THE Alpha SP+ low backlash planetary gear reducers, available from Treotham Trading , are designed to match the high performance characteristics of ac brushless servo motors.
An optimum gearing geometry guarantees up to 97% efficiency with input speeds up to 6,000rpm.
Operating on a high level of power density, smoothness, low weight and high torsional rigidity, the SP+ works with reduced torsional backlash - less than one arc-minute of backlash on request.
Vibration of the unit is extremely low, thus affording a significant level of precision in a standard gear head to dramatically increase positioning accuracy.
At 6dB(A), the SP+ is about four times quieter than its already quiet forerunners in the SP line.
Alpha introduced new seals developed specifically for the SP+, with both material and geometry optimised to provide true IP65 (optional IP66) protection.
In addition, the output bearing capacity has been optimised to surpass anything in its class.
