A one-start or two-start worm changes the ratio for a given wheel tooth count. Material and finish affect friction and wear. Bearings must react axial and radial loads generated by the mesh.<\/p>\n

If the motor may stall against the load, include that condition in the RFQ. Short peak events can be more severe than normal running torque.<\/p>\n
