Gearbox Torque 2

[mikew79]

Forgive me for the probable ease of this question, but I am an electrical engineer who rarely is involved in this sort of thing, and its a long while since I did this.

Am I still correct in thinking that the maximum output torque of any single stage gearbox particularly planetary, (assuming 100% efficiency) is the input torque applied to the inverse gearbox ratio. Thus given a motor running at 6000RPM able to deliver a torque of 1NM to a load if put through a 10:1 gear box, I get a Running Speed of 6000/10=600RPM and a torque of 1*10=10NM.

Am I correct in assuming that the nominal torque quoted is just the realistic maximum output torque, if the input torque was sufficent. thus if a Nominal torque of 17NM is quoton a 10:1 gearbox you would only achieve 17NM if you applied 1.7 at the Input, so applying the above 1NM would still only give 10NM.

Thanks

As an electrical engineer you should know the reason for your correct answers and that is dependent on the relationship between horsepower, RPM and torque. Consult any ME handbook and your answers will be forthcoming in a section dealing with mechanical power transmission.
