How Is Torque Capability Calculated for Different Gear Configurations?

[simonsong90]

Hi all, I am new to this forum and hope to get some understanding about the torque capability of gear.

Homework Statement

1) Can anyone explain to me about the torque capability?
2) I got some data on torque capability of mod 3.0 spur gear with 50 teeth and 1000rpm, but what i need is to find the torque capability of gear with 59 teeth and 1140 rpm. How can i do that?

Pitch torque check
50 teeth x 1000rpm with module of 3
Torque = 615 Nm
HP = 86

Homework Equations

1HP = 746 W
Power = Torque x angular velocity
No. of teeth x module = diameter

The Attempt at a Solution

I had tried using the ratio method for the 59 teeth and 1140 rpm but doesn't seem right. Anyone have any idea how to do it?
Thanks a lot in advance who ever read this and help me. :D

To calculate the torque capability of gear with 59 teeth and 1140 rpm, you will need to use the following equation: Torque = Power / (angular velocity x no. of teeth x module).In this case, we have the power (86 HP) and the angular velocity (1140 rpm), so we can calculate the torque as follows:Torque = (86 HP x 746 W/HP) / (1140 rpm x 59 teeth x 3 module)Torque = 692 Nm
