Shift the front gears to the smallest ring, and the back gears to the largest cog. Fully wind in the low adjust screw. You should complete this procedure with a slack gear cable, so you can be sure that cable tension isnât overriding your low limit setting.To do this, release the cable retention bolt on the derailleur.our rear high and low limits should now be set. Step 3. Adjust your jockey-wheel clearance by locating the screw on the top-rear of the derailleur. With the bike in the highest gear, the upper jockey wheel should run clear of the cassette.
This indicates a gear ratio of 6.7:1, rounded to 7:1. Recall that with a gearhead, torque rises and output shaft speed drops with the gear ratio. You can now size the gearhead to a motor by figuring 66 oz-in. Ã 1.5 (safety factor) = 100 oz-in. of output torque from the gearhead.This gives 100 oz-in./7 = 14 oz-in. from the motor through the gearbox and 37 rpm Ã 7 = 259 rpm from the motor. In this case, the rpm and torque are more than is required.et us take a concrete example of a Baldor Electric Co. dc motor that generates 11,500 rpm with a 1-in.-pitch-diameter pulley. This configuration will produce a linear speed of 36,128 ipm, or 3,011 fpm, or 602 ips. The pulley size, of course, could be changed to vary the speed or torque.
