Description
This Series of Hand Adjustable Vee pulleys are ideal for low power applications when some variation in speed may be required or the optimum speed can not be determand before hand.
They are designed for use with Vee Belts to Din 2215 and Wedge Belt to Din 7753 and allow you to Increase or Decrease the PCD by hand adjustment of one Flange along a screw thread and are available as a pilot bore type for machining to suit the final shaft size or as a Taper Bored type for use with a Taper bush.
Adjustment is by quarter turns of the threaded Flange using the four Setscrews positioned over the four flats.
The amount of full turns required to acheive a particular PCD can be calculated using the following formula :-
Example: to adjust type RS187-A1 to pitch diameter 165.0mm. At totally closed pulley pitch diameter is 181.0mm
Max pcd – required pcd = 181-165
—————————– ———- = 2-3/4 turns of the screw on nut.
4 x adjusting factor 4 x 1.45
