    Precision Wormwheels

    Worm & Wormwheel Ratios.
    The number of starts [z1] on the worm and [z] teeth on the wheel  give you the ratio.

    Examples:-
    PWG2.5-15/1     -  1 [z1] Start Worm   15z  Wheel  Ratio [u] i=    15/1 = 15:1
    PWG0.5-100/2    - 2 [z1] Start Worm  100z  Wheel  Ratio [u] i= 100/2  = 50:1
    The wormwheels mate with the same number of start [z1] worm.

    We can supply to standard, modified or customers drawings and specifications with full traceability, first article inspection reports (F.A.I.R), and inspection reports.
