STOBER Drives, Inc., a high-efficiency gearbox manufacturer in Maysville, Ky., wants to remind you of all the sizes available for its PHQ series.
The PHQ is available in sizes 4, 5, 7, 8, 9, 10, and 11. How does it differ from STOBER’s PH unit? The PHQ features a high torque, four-planet design, allowing torque to be distributed over four planet gears instead of three. This results in an increase in output torque and torsional rigidity, while still providing low backlash and smoothness of operation.
The PHQ4 and PHQ5 are available in single and double stage, with ratios ranging from 5.5:1 to 55:1. These gearheads are capable of 430 Nm of acceleration torque. The PHQ7 thru PHQ11 are available in double and triple stage, with ratios ranging from 22:1 up to 600:1, and up to 22,000 Nm of acceleration torque.
With a backlash rating of three arc minutes, the PHQ is ideal for applications requiring low backlash, such as robotics, injection molding for plastics, and tube-bending industries. For applications requiring even lower backlash, the PHQA version is capable of having backlash as low as 1 arc minute.
