Final Max Output Torque of a Gear Drive

Two more motors, and slightly higher pressure?

Tornado is right, except for one flaw in the logic.

The max torque value will be at a speed that is lower than the Max Speed- Power figure given.

As for most motors, the max torque (as distinct from torque at max power) will be higher and at some mid speed range figure.

What you have not got in your calculation, and which makes it all fit together is the speed torque curve for the hydraulic motors.

...and the max torque isn't the running torque.

At the max torque one might reasonably expect the overload trip device to become a bit anxious about operating. Anything more, and it ought to operate to protect everything. And if it doesn't operate the wrong side of the max torque, then it is incorrectly set.

People get a bit obsessed with torque on motors in this forum, it seems. Torque is what the load presents to the motor, not the other way round.

The two motors are synchronised , logicaly the havre the some torque. Make à calculation for one motos and muliply bye two .

I figured out what I was doing wrong or leaving out. I kept just using the theoretical torque at 100 bar and not considering variable pressure and speed. I found a chart for the motor showing different values at different pressures and this helped solve my calculation problems. I still have much more to learn here or remember what I had learned but forgot since I had not been using these type of calculations for many years. Thank you all for your help, comments and input on this topic. I will have to take those college books off the shelf and refresh my knowledge and work on the next design.
