hey Chris, Its a real Gear box. I drew the sketch up to calculate the gear ratio. Its an old motor. I know what the motor specs are, but i don't have the reduction ratio and hence I am trying to calculate it. i is the number of teeth. In the diagram, the diameter and number of teeth for each...

Hey, So if i want to calculate the overall reduction ratio of the system, i will have to multiply the individual ratios of the gears won't i? I can then get my overall ratio. I am not if this is the right way of going about it though! This way, i got the overall reduction to be 83 to 1. But i...

http://C:\Documents and Settings\design3\Desktop\piccs Hey, I want to know how to calculate the gear ratio of the given arrangement in the picture. I am not sure of how to calculate the gear ratio of two gears on the same shaft. Also the input gear is helical and the output gear is a spur...

The set up will be powered by dry cell batteries. I calculated the torque using a motor sizing tool online based on my weight, average speed etc. I require an average speed of 1.2 m/s which is approx 50rpm based on my wheel dia. Speed at the motor is 1500rpm so i will be using a gear reduction...

Hey, I found a 12V, 120A motor. But I am trying to figure out if i should go with one motor to run both wheels or two motors(to run each wheel separately). Will I need a differential in both cases or only with the one motor setup? Cause steering will be done manually so I am worried that it...

Okay so here's the thing. I need the trolley to move in the forward direction with a slight push and in the backward direction with a slight pull. So by applying slight force in either front or backward direction, the motor takes over and the trolley moves. I want to know if this is possible and...

Here are the specifications of the motor if it helps :) Power: 2HP Torque: 400 Nm Voltage: 12V/24V Current: 120 A Number of Drive Wheels: 2 Diameter of drive wheels: .435m Type of motor: PMDC Gear Reduction set up: Worm drive arrangement Total weight being driven: 700kgs Speed at...

@Okefenokee: I want to know how i can get it moving in the forward direction with a slight push and in the backward direction with a slight pull. @ SirAskalot: I initially wanted to go with a PMDC(Permanent Magnet) Motor that will run both wheels. I want to know if it possible to come up with a...

hey, So I am working on this project where I am trying to come up with a motor set up to drive two wheels of a trolley. The entire trolley weighs 650 kgs and i require a motor with a torque of about 400Nm. I want to set it up in such a way that i want to be able to apply very little force to...
