Question

A helical gear has 30 teeth and a pitch diameter of 280 mm. Gear module is 8 and pressure angle normal to tooth is 20°. The force normal to the tooth surface is 4500 N. Determine the kW transmitted at 620 rpm.

Answer 1

Answer:

The answer is 30 N a foot.

Explanation:

Answer 2

The power in kW transmitted at 620 rpm is 40.88 kW.

What are gears?

A gear is component used to transmit motion. They are used in cars, trucks, machines, bicycles, etc.

A helical gear has 30 teeth and a pitch diameter of 280 mm. Gear module is 8 and pressure angle normal to tooth is 20°. The force normal to the tooth surface is 4500 N. Speed is 620 RPM.

The torque obtained on the gear will be

T = Force x Radius

T = 4500 x (0.280/2)

T = 630 N.m

Power Transmitted P = T ω = 2πNT/60

Plug the values, we get

P = 2π x 620 x 630 /60

P = 40882.8 W

P = 40.88 kW

Thus, the power in kW transmitted at 620 rpm is 40.88 kW.
