Model For 219 Chain 20 Tooth Sprocket Series Of Inner

From the tests that we have done, they seem to be just as durable (if not MORE) than the AFAMs that are made out of 7075-T6 but with the blue ornamental anodizing.

By far the best aluminum sprockets on the market Colors may vary between blue and silver, laser etching may vary between RK, NKP and XAM, all the same.

PLEASE NOTE: RK sprockets are increasingly getting difficult to get.

If not available, check Wildkart sprockets, same material, quality and price.

Sprockets and chain can be used to change the speed, torque or direction of a motor.

For sprockets and chain to be compatible with each other, they must have the same thickness and pitch.

Sprocket and chain is a very efficient way to transmit torque over long distances.

Sprockets consist of a disk with straight teeth projecting radially.

Sprockets will only work correctly with chain and other sprockets if they are on parallel shafts and the teeth are in the same plane.

A chain consists of a continuous set of links that ride on the sprockets to transmit motion.

The REV 15mm Build System is designed around 25 Roller Chain ( REV-41-1365 ) using compatible 25 Sprockets.

Anatomy of a Sprocket The most common and important features of a sprocket are called out in the figure below.

Number of Teeth Pitch Diameter Pitch Outside Diameter Chain Clearance Diameter Number of Teeth Number of Teeth is the total count of the number of teeth (projections) around the whole circumference of a sprocket.

For sprockets with very few teeth this number is easily physically counted, but for high tooth counts this may not be isnt very practical.

Pitch Diameter Pitch Diameter (PD) is an imaginary circle which is traced by the center of the chain pins when the sprocket rotates while meshed with a chain.

The ratio of the pitch diameter between sprockets can be used to calculate the gear ratio, but more commonly and much more simply the ratio of the number of teeth is used for this calculation.

Pitch Pitch represents the amount of pitch diameter in inches per tooth.

Common pitches are 0.25, known as 25, and 0.375 (35).

The REV Robotics building system uses 25 chain.

Outside Diameter Outside Diameter (OD) will always be larger than the pitch diameter but smaller than the chain clearance diameter.

The outside diameter does not account for the additional diameter added by the chain, so it should not be used to check for assembly interference.

Chain Clearance Diameter Chain Clearance Diameter is the outside diameter of a sprocket with chain wrapped around it.

The chain clearance diameter will always be larger than the pitch diameter and the outside diameter.

The chain clearance diameter should be used when checking for interference when placing sprockets very close to other structures.

Anatomy of Chain Roller chain is used to connect two sprockets together and transfer torque.

Model For 219 Chain 20 Tooth Sprocket Series Of Inner

Roller chain is made up of a series of inner and outer links connected together which forms a flexible strand.

Outside Links Inside Links Pitch Outside Links Outside Links consist of two outside plates which are connected by two pins that are pressed into each plate.

The pins in the outside link go through the inside of the hollow bushings when the inner and outer links are assembled.

Inside Links Inside Link consist of two inside plates that are connected by two hollow bushings which are pressed into each plate.
