Torque on a shaft

    If a motor has a horsepower of 5hp and a gear box ratio of 10:1 does the hp through out the system remain 5? or does the gear box multiply the power?

    how does this affect the torque?

    Power is constant through a transmission and is the product of torque and angle rate.

    ...minus the loss due to inefficiencies. Not to nitpick on you Doug Huffman, but considering the OP's question I think it is worthy of pointing out.

    power out = power in * efficiency
    torque out = torque in * (input speed / output speed) * efficiency
