V-belt Flashcards
belt deflection force
how much forve is needed to deflect the belt a certain distance
what is the upper limit of the acceptable tension force
50% greater than the lower limit
what is the ideal tension force
between the force level listed in the table and 1.5 times that value
how can you apply tension to the belt
by moving it with either a pry bar, punch, or adjustable mounting base
what are the three ways that belt tension can be measured
hand pressure
tension tester
spring scale and straight edge
hand pressure tension tester
strike the belt with hand, it will fell alive and springy when tensioned correctly
wedge belts cannot be tested this way
tension tester
More accurate than hand method
handheld device which measures the belt tension bu measuring the force needed to deflect the belt a certain amount
spring scale and straight edge method
similar to tension tester
spring scale is used to deflect the belt, the the amount is measured with a ruler
