Total questions: 20
Worksheet time: 14mins
One of the following is not considered as advantage for the V-Belt drive :
It is inexpensive
Requires lubrication
Accepts greater misalignment than chains/gears
Absorbs shock loads
for the system shown in the figure ( A) represent :
Driver Sheave
V belt
The pump
The shaft
for the system shown in the figure ( B) represent :
Driver Sheave
V belt
The pump
The shaft
The ratio of the sizes of the sheaves is selected to either decrease or increase the (a) and torque delivered to the driven shaft.
Belt is usually rubber, stretched between the two sheaves, transmits speed and torque by (a) between it and the sheave grooves
The distances shown in the figure A/B/C represent the (a)
For the shown belt system ( A) represent :
Bottom of sheave groove
Pitch diameter
Pitch circle
Sheave circle
For the shown belt system ( E) represent :
Bottom of sheave groove
Pitch diameter
Pitch circle
Sheave circle
For the shown belt system ( C) represent :
Bottom of sheave groove
Pitch diameter
Pitch circle
Sheave circle
Calculate the pulley ratio of the belt drive system shown
