How do you calculate gear ratio reduction?

How do you calculate gear ratio reduction?

The “reduction” or gear ratio is calculated by dividing the number of teeth on the large gear by the number of teeth on the small gear. For example, if an electric motor drives a 13-tooth pinion gear that meshes with a 65-tooth gear, a reduction of 5:1 is achieved (65 / 13 = 5).

What is the formula for calculating gear ratio?

The gear ratio is calculated by dividing the output speed by the input speed (i= Ws/ We) or by dividing the number of teeth of the driving gear by the number of teeth of the driven gear (i= Ze/ Zs).

How do you calculate rpm for gear reduction?

Calculate the reduction by dividing 12 by 5, which equals 2.4. The RPM of the assembly is the RPM motor divided by the reduction. In our example, it would be 5000 RPM/2.4 = 2083 RPM.

What does a gear reduction do on a ATV?

You can spin that gear as fast as you want, but as soon as you hit any resistance, it’ll stop dead. That’s why you mostly see gear reductions that increase your torque and decrease speed. That trade-off is much more favorable because the extra torque will make up for a lot of the lost speed when you’re riding off road.

How is differential gear ratio calculated?

The calculation uses the number of teeth in the ring gear and divides it by the number of teeth in the pinion gear to provide you with a “[result] to 1” ratio. For example, if the pinion gear has 41 teeth, and the ring gear has 11 teeth, the ratio would be calculated as 41/11, which is equal to 3.73 = 3.73:1.

How do you calculate gear ratio with torque?

How to Calculate Gear Ratios and Torque

1. Multiply the force acting on the first gear by the first gear’s radius.
2. Divide the second gear’s radius by the first gear’s.
3. Multiply the gear ratio by the input torque that you calculated in Step 1: 2 x 600 = 1,200 newton-meters.

What is gear reduction?

A reduction gear is an arrangement by which an input speed can be lowered for a requirement of slower output speed, with same or more output torque. The high speed incoming motion from the wheel work is transmitted to the set of rotating gears, wherein the motion or torque is changed.

How do you calculate RPM ratio?

The general rule is – small to large gear means ‘divide’ the velocity ratio by the rpm of the first gear. Divide 75 teeth by 25 teeth to find the velocity ratio. divide the 60rpm by the velocity ration (3). The answer is 20rpm.

What does 30\% gear reduction mean?

A 30\% gear reduction is perfect for 32” to 40” tires depending on what machine you have. With bigger tires, you can go deeper and crawl harder. Your extra clearance means you’ll keep your machine from getting stuck in the rocks and keep your head above the mud.

How does gear reduction work?

Can you change the gear ratio on an ATV?

The two main reasons to alter the gear ratio of your ATV is to get more acceleration or to get more top speed. A lot of riders will use terms like ‘gear up’ or ‘gear down’ to describe the changes to their gear ratio by swapping out a sprocket for one with a different number of teeth.

What is the gear ratio of a Baja car?

selected for a Baja vehicle, the fixed gear ratio must be selected. Based on available literature, the overall gear ratio of Baja cars are typically near 35:1. For example, the 2012 Michigan team produced a fixed gear ratio of 10:5:1

How do you calculate gear ratio on a front wheel?

Gear Ratio Calculations And Terms. To obtain your gear ratio is simple, you can use the chart provided below, or simply divide the number of teeth on the rear sprocket, by the number of teeth on the front sprocket. For example if your rear sprocket had 40 teeth and your front sprocket had 12 teeth. 40/12 = 3.33, your gear ratio would be 3.33.

How does gear ratio affect top speed?

Just remember, the smaller the gear ratio number, the more top speed you’ll get. The larger the gear ratio number, the more acceleration you’ll get. To obtain your gear ratio is simple, you can use the chart provided below, or simply divide the number of teeth on the rear sprocket, by the number of teeth on the front sprocket.
