# How do you calculate chain drive?

## How do you calculate chain drive?

The chain drive trajectory is based on individual sprocket position and desired direction of motion….Meaning of used variables:

C 0 Desired center distance [m]
p Chain pitch [m]
z 1 Number of teeth of the driver sprocket [-]
z 2 Number of teeth of the driven sprocket [-]
D P1 Pitch diameter of the driver sprocket [m]

## How do you calculate chain force?

Since power = torque x RPM x 2 x π, then torque = power/(RPM x 2 x pi) (i.e., power divided by angular speed). And force = torque/radius, so force = (power/(2 x π x RPM))/radius, or force = power/(2 x π x RPM x radius).

How do you calculate motor power for a conveyor chain?

Calculation of load moment of inertia

1. 5.1 Calculation result (load moment of inertia) ① Moment of inertia of carrier and chain or belt (Converted in a motor shaft) JW＝（（W＋B）／4）×（D×P2）2／（π*1000×P1×Z）2
2. 5.2 The moment of inertia of total load. Input mass of sprocket, drum, gear etc.

### How do you calculate chain speed?

Formula for Chain Speed Calculation Take chain pitch and multiply x two. Multiply above number by number of teeth on sprocket of saw. Multiply that number by saw RPM. The number you get will be chain speed in inches per minute.

### How do you calculate chain length?

L = 2 (C) + (F/4 + R/4 + 1) L = Length – your chain length in inches (rounded to the nearest inch). C = Chain stay – the distance between the middle of the crank to the rear axle. Measure to the closest ⅛ and convert this to decimal form.

How do you calculate chain work load?

Working Load Limit is calculated by dividing the minimum breaking strength of the chain by the assigned safety factor rating. The grade and diameter of the chain is also used to determine the working load limit.

## How do you calculate chain and sprockets?

The easiest way to calculate sprocket ratio is to count the number of teeth on both the driving and the driven sprockets and divide the first by the second. This ratio tells you how many times the driven sprocket turns for every revolution of the driving sprocket.

## How do you calculate the breaking load of a chain?

The WLL is calculated by dividing MBL by a safety factor (SF). An example of this would be a chain that has a MBL of 2000 lbf (8.89 kN) would have a SWL or WLL of 400 lbf (1.78 kN) if a safety factor of 5 (5:1, 5 to 1, or 1/5) is used.

What is chain speed?

The chain speed, the distance travelled by the chain in a given unit of time, is a fundamental factor in determining the conveyor capacity. It is from this parametr that chain pitch and the diameter of the driven wheels is derived.

### How to calculate a chain drive?

To calculate the chain drive, it is necessary to set the drive pulley speed n, power P, gear ratio i , number of chain rows m and angle of inclination Θ of the line, connecting the centers of the drive’s shafts.

### What is the optimum speed ratio for a chain drive?

So, an optimum speed for chain drive must be obtained. The speed ratio between small and big sprockets must be lower than 7. You can also design it with much higher speed ratio numbers. But, in the application, it will be safe to design two or more steps of chain drives for bigger speed ratios.

What is a chain drive mechanism?

Chain drive mechanisms are very important to power transmission mechanisms used in such types of machinery. Typical chain drive includes link plates that are linked with rollers. These rollers are attached to link plated on both sides with pins. With the respective alignment of this assembly, long chains are obtained.

## How to calculate the chain length for your application?

This calculator provides you to calculate the required chain length for your application. What you need to do is, just enter the center distance C (meters, millimeters, inches…) and the number of teeth of the small sprocket (N1), and the number of teeth of the big sprocket (N2). Click on the ‘Calculate!’ button to see the required chain length.
