How much torque do you need to apply to a pulley?
You have a socket set with 2 bars, one 1.0 m long and one 0.5 m long. To apply the same torque to the bolt, the 1.0 m bar requires 100 N applied to the end. The 0.5 m bar requires 200 N applied. In your example, the torque applied by your motor to a small shaft or a large pulley will be the same. 1450 Nm.
How much torque does a rear wheel pulley sprocket have?
Anyone know the torque spec on the rear wheel pulley/sprocket? 99 FXDX. Do the bolts require lock tite? I don’t have specifics for your ’99, my ’92 FIVE speed is 110-120 lbs.ft.
How big is the pulley in a motor?
It may help to imagine your shaft and pulley as 2 different levers welded to the motor spindle. One is 37.5 mm long (the shaft) and one is 88.9 mm long (the pulley). Clearly the shorter lever will need more force to stall the motor. A Newton metre is a unit of torque (also called “moment”) in the SI system.
Is it possible to bypass a pulley wheel?
You might be able to bypass the pulley altogether, and simply super glue and wrap the string directly around the shaft. It’s worth remembering that although a smaller pulley wheel means the motor will be able to lift a heavier weight, it will take longer to lift the mass.
How much torque does a 34in pulley have?
So continuing on through the drive train, pulley #2 (34in one from above) and pulley #3 (10in OD) are rigidly fixed on the same axle/jackshaft. Therefore torque in = torque out, power in=power out and rpm in =rpm out. We know the torque from above at the 34in pulley is 7042Nm.
How much torque does a pulley to wheel hub have?
I use loctite on the small bolts that hole the retaining clip. I think you have asked for the rear pulley fastener bolts. Pulley to wheel hub. I believe they are 7/16 bolts. Torque would be 40- 50 foot lbs. with blue locktite. I think you have asked for the rear pulley fastener bolts. Pulley to wheel hub.
How to calculate motor drive torque for belt and pulley systems?
The motors of choice for these systems are often servo motors, for their ability to accurately control position, speed, and torque. Sizing and selecting the servo motor requires determining both the continuous and intermittent drive torques required for the application.
Which is the best motor for a pulley?
So for our required torque, there are several motors which will be able to do the job, such as the 215-400 Micro Spur 16mm DC Gearmotor – 38mm type , which has a rated torque of 150mNm. Rearrange equation 2 for the radius, r: Note that the minimum diameter of your pulley is limited by the shaft diameter of your motor.
