CATALOGUE SELECTION Motor selection: So for this project, we want a cheap motor to save on cost, so we should use a two-pole motor

N

&#;

60

N

=

without load

N

=

RPM

with load Now with the two-pole motor, the speed at which it runs when it's connected to a worm gear unit, the fluid within the unit will start to overheat, so we would have to use a four-pole motor because of the shaft speed would.be lower RPM N4pole

. Gear ratio selection:

VR

VR

22.5

&#;

So first, we need to look at Renolds worm gear catalogue, Page 37, gear rations single reduction. Since we have a total gear ratio in the system of

22.5

, The two options are 7.5:1 worm gear

22.5/7.5

=

3

So 3:1 for the chain gears. The other option is

12.5

worm gear

22.5/12.5

=

1.8

So

1.8

:

1

chain gears from Renolds transmission chain catalogue Page 27 chart 1 with a chain gear ratio of 3:1 sprocket,

1

(

Z

has 19 teeth, and sprocket

(

has 57 teeth, find the application Factor (f1) from the transmission chain catalogue Page 28, chart 2 since we are using an electric motor as our drive unit it's classified as a smooth running driver unit, and the driven machine characteristics are heavy shocks due to lifting an enginetransmission unit for serval hours per day,

Since we want the cheapest solution, we should select a simplex chain setup From graph We would be selecting a

15.875

 

mm

chain pitch that has to be drip feed oil, so with an option, we should have a chain solution that can be manually oiled. So we need to select. 12.5:1 worm gear and 1.8:1 chain gear
