QUALITY

Performance

Service

Product specifications subject to change without notice. Fulton, Illinois USA Some products shown proprietary.

Wide Waist

The wide waist design of 60H and larger chains reduces

the bending stress in the link plate which increases the fatigue strength of the chain.

Solid Rollers

Drives utilizes solid rollers on all carbon roller chains. The solid roller allows for smooth rotation on the bushing, minimizing the impact load as the chain engages the sprocket tooth.

Factory

Preloading

Drives precision roller

chains are

preloaded during assembly. Preloading the chain seats the chain components, which minimizes the initial elongation of the chain.

Shot Peened Parts

All precision chain rollers and link plates are shot peened for greater fatigue strength.

Heat Treatment

Rigorous process controls and state

of the art heat treating furnaces assure consistent quality in all chain components. This results in optimum toughness and resistance to wear.

Prelubrication

After final assembly, the roller chains are hot dipped in a special lubricant. This process assures that all the load bearing surfaces are protected from metal to metal contact, improving the wear life of the chain.

Automated Assembly Roller chain assembly methods assure consistent processes and proper assembly of chain components.

Connecting Links

Standard connecting links are used when roller chains are operated under normal conditions. For severe applications, press fit connecting links are suggested. Spring clip style connecting links are used for sizes 60H and smaller. Sizes 80 – 180H use a special hardened hook cotter. Coated

T-pin is used on 200, 264

and 240.

Offset Links

Offset links are used when the chain length is an odd number of pitches; however their fatigue strength is lower than standard chain links. Use of offsets should be avoided when possible.

Horsepower Rating

The horsepower rating in Table IV on page 10 is based on the following conditions:

1.
Chains are operated under ordinary conditions. The ambient temperature range must be between 15°F and 140°F. They should not be used in an atmosphere in which abrasive dust or corrosive gas is present or where the humidity is high.

2.
Two transmission shafts are in a horizontal position, and the chains are properly installed.

3.
Suggested lubrication system and oil are used.

4.
Load does not change significantly during transmission. The “Service Factors” given in Table I should be taken into account when the chains are used under various operating conditions. The load conditions will affect the life of the chain.

5.
In order to estimate the service life of a multiple strand chain, the “Multiple Strand Factor” given in Table II must be used. When the chain length is 100 pitches and the above conditions are met, a service life of approximately 15,000 hours can be expected.

Procedures for Selecting Roller Chain

1.
The following factors must be considered when selecting roller chain:

2.
Use Table I to obtain the “Service Factor”.

3.
Multiply the horsepower value by the service factor to obtain the design horsepower value.

4.
Use Table IV on page 10 and the horsepower ratings table to obtain the appropriate chain number of teeth for small sprockets. Refer to the number of revolutions of the high speed shaft (the driving shaft when the speed is reduced; the driven shaft when the speed is increased) and the design horsepower value. For smoother chain drive, a small pitch chain is suggested. If a single strand chain does not satisfy the transmission requirements, use a multiple strand chain. If there are space limitations, a multiple strand roller chain with a smaller pitch may be used.

a. Source of input power

b. Drive machine type of driven equipment

c. Horsepower to be transmitted

d. RPM of driving and driven shafts

e. Diameter of driving and driven shafts

f. Center distance of the shafts

5.
After determining the number of teeth necessary for the small sprocket, be sure the sprocket diameter satisfies the space limitations.

6.
The number of teeth for the large sprocket is determined by multiplying the number of teeth for the small sprocket by the speed ratio. More than 15 teeth on the small sprocket is suggested. The number of teeth for the large sprocket should be less than 120. By reducing the number of teeth for the small sprocket, the number of teeth for the

large sprocket can be reduced.

Basic Formula for Chain Drive

1. Chain speed: S PC x N x n

Drive Selection Procedure

Selection Example (1)

Q1. A centrifugal compressor with 3HP is driven by

an 1800rpm electric motor. How to select chain and

sprockets.

A1. Seek the service factor, 1.3, from Table I

Power to be transmitted x Service factor = Design Horsepower

3HP X 1.3 = 3.9HP

2.
Refer to Table IV. Horsepower Rating Table for 1800rpm 3.9HP and 35 chain with sprocket 16T to 20T is obtained.

3.
Check horsepower ratings for chain 35, and as you see, the horsepower ratings of 35 17T with speed of 1800rpm is 3.93HP, which is satisfactory.

4.
The following are selected: Chain No 35 Small sprocket 35 17T.

Selection Example (2)

Q1.The number of revolutions for drive is 500rpm and the power to be transmitted is 10HP. The rpm is reduced to 125 (1/4). The center distance should be 11.00” with a space limitation of 19.00”, and a uniform load. How to select chain and sprocket for this application.

A1. Design horsepower is computed as follows: Design horsepower: 10HP X 1.0 = 10HP

2.
Select chain and the number of teeth for sprocket by referring to Table IV, Horsepower Rating Table.

60 18T has been selected. 125rpm

3.
Speed reduction ratio is 0.25 =

500rpm Therefore, the number of teeth in the large sprocket is 18T

72T = 0.25

4. The outside diameter of the 18T is 4.685” and the 72T is 17.60”.

The space required for this arrangement is 4.685” + 17.60”

+ 11” = 22.14”

2 which can not be contained in the 19”.

5. Multiple strand chain is selected. 50-2 16T to 20T is

selected using Table II. 10HP x 1.0

= 5.88HP

1.7

(1.7 is multiple strand factor)

Refer to horsepower ratings. 50-2, 18T is obtained. It’s outside diameter is 3.90”. The large sprocket is 18T

72T = outside diameter 14.69”.

0.25 However, this selection cannot be contained in the space.

6. Triple strand chain is selected in the same manner as above. 50 -3, 13T and 52T are obtained. The outside diameter of sprockets is 2.87”, and 10.67” respectively.

+ 11” = 17.77”can be contained 2.87” + 10.67”

in the space required.

The chain and sprockets selected are 50-3, 13T and 52T.

Horsepower Rating Table

Selection of Chain and Small Sprocket

Chain Pitch

The smallest applicable pitch is desirable for quiet operation and for high speed.

Number of Sprocket Teeth

For a given chain pitch and shaft to transmit a given horsepower, the effect of increasing the number of teeth in the sprocket is to increase the chain linear speed and decrease the chain pull proportionally, resulting in a decrease of the chordal

Table IV - Roller Chain Pitch Selection

action, which results in a quiet drive with less impact.

Usually, large sprockets should not exceed 120 teeth although many successful drives use sprockets with 150 teeth and more.

Selection of Large Sprocket

After the small sprocket has been selected, the number of teeth in the large sprocket is determined by the specified ratio of the shaft speeds.
