What is compound gear train?

What is compound gear train?

A compound gear is a number of gears fixed together. Consequently, they rotate at the same speed. The gear train below has an arrangement of gear wheels including two compound gears. Gear trains like this are often found inside machines such as centre lathes and milling machines.

How is gear train torque calculated?

Multiply the force acting on the first gear by the first gear’s radius. If, for instance, a force of 4,000 newtons acts on the gear, and it measures 0.15 meters in radius, 4,000 x 0.15 = 600. The gear turns with 600 newton-meters of torque.

How do you calculate gear rpm?

In the example below the DRIVER gear is large than the DRIVEN gear. The general rule is – large to small gear means ‘multiply’ the velocity ratio by the rpm of the first gear. Divide 60 teeth by 30 teeth to find the velocity ratio. Multiply this number (2) by the rpm (120).

What gear ratio is best for gas mileage?

The lower the number, the better fuel economy, and the higher the number the more towing power you have, but fuel economy suffers. For instance, a 3:31 gets better fuel economy than a 3:73. On the other hand, a 3:73 or perhaps a 4:10 will tow much more, while fuel economy greatly drops.

How do I know what gear ratio my front differential is?

Divide the number of driveshaft turns you counted by 10 (same for both LSD/Locker and open). That’s your gear ratio.

What gear ratio do I have by Vin?

Check the bolts on the differentials. There should be a tag on one of them. The codes on that tag will tell you the gear ratio. The VIN will not give you gear ratios in most cases.

How do I find my axle gear ratio?

Here are two ways to find the axle gear ratio of a vehicle: Method 1: Count the number of teeth on the ring gear and the pinion. Divide the number of the ring gear’s teeth by the number of the pinion’s teeth. This will give you the axle ratio.

How do I find the axle ratio on my VIN number?

How to Find Out the Gear Ratio With the VIN Number

1. Find the VIN of your vehicle. It can be found on the sticker on the inside of the driver’s side door or on a stamped metal plate embedded in the dashboard above the steering wheel.
2. Identify the VDS section, the fourth through eighth digits of the VIN.

How do I know what rear axle I have?

It’s worth noting that rear axles can sometimes be positively identified by a casting number and date stamped on the differential cover or axle tube. However, road debris, dirt, grime, and general age can obscure these numbers.

How do I identify my Chevy rear axle?

Identify your GMC or Chevrolet rear end gear ratio by the RPO Codes, usually located on the placard labeled “Service Parts Identification” inside the drivers door panel or glove box.
