LAP 4 Intro to V-Belt Drives
A common belt used for conveyors is the ________ belt.
flat
A(n) _______________________ v-belt is a light duty belt designed for lower power applications and intermittent running.
fractional horsepower (FHP)
A belt drive has three features derived from the concept of pitch: pitch diameter, pitch circle, and pitch ______.
length
The specific force for a belt is determined using the belt size, sheave size, ___________________, and whether or not it is new or old.
operating speed
The _______________ is determined by dividing the pitch diameter of the driven pulled by the pitch diameter of the driver pulley.
pulley ratio
Another name for a sheave is a(n) ____________.
pully
The __________________ of the driven sheave and the driver sheave determine the speed and torque transmitted to the driven shaft.
relative diameter
A(n) ________________ is used to check a sheave for wear.
sheave gauge
A v-belt _________________ (should/should not) touch the bottom of the sheave.
should not
A spring scale can be used with a(n) _________________ to measure belt tension.
straight edge
Pitch is defined as the distance between a point and a similar corresponding point. (true/false)
true
The ____ belt is designed to grip the walls of a grooved pulley.
v
The hand pressure method of belt tensioning requires you to strike the belt with __________________.
your hand
One method of adjusting belt tension is using a(n) ___________________ motor base.
adjustable
The method used to measure belt tension is called __________________.
belt deflection method
The _______________ is the distance between the points on the sheaves where the belt touches each sheave.
belt span
The force _____________ method uses a tension tester to measure belt tension.
deflection
The pulley ratio is determined by dividing the ____________ rotational speed by the _________ rotational speed.
driver driven
Tension is applied to a belt by moving the _________________ away from the ______________.
driver motor driven shaft
