Belt drive selection procedure

Before designing a Poly Chain® GT2 synchronousbelt drive, you need to determine following driverequirements:

1. power requirement and type of driveN machine2. the rpm of the driveR machine3. the rpm of the driveN machine4. the approximate centre distance for the drive5. hours per day operation

To select a Gates Poly Chain® GT2 belt drive, youneed to complete the following steps:

STEP 1

CALCULATE THE DESIGN POWER

Design power = service factor x powerrequirement

A. To calculate the design power it is necessary todetermine the service factor for the drive.Determine the type of the driveR machine usingthe service factor chart.

B. Using the service factor chart, determine theservice factor for the driveN machine and the typeof operational service.

C. Multiply the power requirement of the drive bythe service factor you have selected. This givesyou the design power for use in designing thedrive.

• The belt’s teeth and body are made of a lightweightpolyurethane compound, specially blended for adhesionto the cords and fabric. This uniquely formulatedpolyurethane makes the belt tough and virtually immuneto abrasion and chemicals.

• The aramid tensile cords provide extraordinary powercarrying capacity. Flex fatigue life of aramid isexceptional, and its high impact strength withstandsshocks and surge loading.

• The fabric covering the teeth is highly resistant to oil,chemicals, pollutants, corrosion and abrasion. It isexceptionally durable and remains fully operational underextreme temperatures from -54°C up to +85°C. Thefabric facing reduces friction with the pulley, therebyminimising temperature build-up.

Features

Benefits

• Substantially increased power rating.

• Highly efficient positive drive.

• Maintenance-free: no lubrication or re-tensioning needed.

• Savings in space, weight and money.

System Specification

We accept payment by Cash, Cheque, VISA and Mastercard.

The three principal dimensions of a pulley are- pitch;- number of grooves;- belt width.

On the pulley, pitch is the distance between groove centres and is measured on the pulley’s pitch circle. The pitch circleof the pulley coincides with the pitch line of the belt engaging with it. The pulley’s pitch diameter is always greater thanits outside diameter.

Any Poly Chain® GT2 belt must be run with pulleys of the same pitch. Poly Chain® GT2 belts can be used on existing Poly Chain® GT drives. They operate on the same pulleys and do not require any adaptation of the system. Pulleys for Poly Chain® GT2 belts aremade in 8 mm and 14 mm pitches. Standard pulley sizes are listed on. For each Poly Chain® GT2 belt width, there is atable listing the pulley codes, the applicable bushing style and pertinent dimensional information. Reference to the stockbushings for Poly Chain® GT pulleys plus bore and keyway information is available to order the correct bushing.The pulley ordering code is composed as follows:

Example: PCGT 8M 22S 128M Pitch 8 mm22S 22 teeth (S stands for pulley)12 Belt width (mm)

The three principal dimensions of aPoly Chain® GT2 belt arepitch;pitch length;width.Belt pitch is the distance inmillimetres between two adjacenttooth centres as measured on the pitch line of thebelt. Belt pitch length is the total length (circumference) in millimetresas measured along the pitch line. The theoretical pitch line of a Poly Chain® GT2 belt lies within the tensile member. Gates Poly Chain® GT2 belts are made in 8 mm and 14 mm pitches.
