Transcript of Bevel Gear Assembly

Bevel Gear Assembly 1. What is the angle of the input shaft compared to the output shaft? The angle of the input shaft and output shaft are interecting.


2. Is the speed increased, decreased, or constant? The speed is increased.


3. Is the torque increased, decreased, or constant? The torque is decreased


4. What is the gear ratio?


5. Is the flow of power reversible? (Can you make the input shaft turn by turning the output shaft?) Yes, you can.
Mechanical Gears Simple Gear with Idler 1. What is the position of the input shaft compared to the output shaft



2. Is the speed increased, decreased, or constant?



3. Is the torque increased, decreased, or constant?



4. What is the gear ratio?



5. Is the flow of power reversible? (Can you make the input shaft turn by turning the output shaft?)



6. Compare the direction of travel between the input and output gears.
Crown and Pinion 90 angle
speed is decreased
torque is increased
gear ratio 3.2:1
Flow of power
reversible
Direction of travel reversible
Rack and Pinion Input movement
rotary
output movement
linear
distance is
2in
With a larger pinion gear-
the rack will move a larger distance
flow of power
reversible
direction of travel
reversible
Pulley and Belt Input shaft and output shaft
parallel
speed is increased
torqueis decreased
ratio 1:2.5
Flow of power
reversible
open belt wheels turn in same direction
crossed belt wheel turns in opposite directions
Cam and Follower Input movent is rotary
Output movement is reciprocating
Follower moves up and down
1 time for every revolution of the crank
Flow of power
not reversible
direction of travel
reversible
Crank and Slider Input is rotary
output is reciprocating
slider moves
1in- diameter of crank
increased crank
increased
distance slider
moves
