C1-2 TB Wood’s 888-829-6637 .....P-1686-TBW 9/20
Synchronous Belt Drives
Features
Positive Slip-Proof EngagementBecause the teeth of the Synchronous Belt mesh with sprocket grooves, there is no creepage to cause speed variations. Powerful tensile cords can’t stretch, so take-up is eliminated from drive maintenance. Precision is guaranteed. This feature is especially important in printing, packaging and material-handling where synchronization is a necessity. Because of this, Synchronous Drives have replaced gears and silent chain in these and many similar applications.
Wide Speed RangeDrives, such as chains perform best within a limited range of speeds. With Synchronous Drives, the speed range is more than doubled. This feature is of special importance when the entire speed range is developed from a single drive such as in DC drives or machine tool applications. Synchronous Belt efficiency remains high throughout the entire speed range.
Constant Driven SpeedsThe unique Synchronous tooth configuration engages and clears each sprocket groove in a continuous flow of quiet, smoothly transmitted power. Thus, angular velocity of the driven sprocket is constant. There is no jerking or vibration caused by chordal rise and fall of the pitch line as occurs in chain drives. There is no loss of speed caused by belt creep or slippage as with flat and V-belts. The Synchronous Drive’s constant output speed is a definite advantage in precision work such as in high-speed printers and machine tools like indexers, drill presses and boring mills.
Wide Range of Load CapacitiesLoad capacities of stock Synchronous Drives range from fractional to hundreds of horsepower. Torque loads range from thousands of foot-pounds to inch-ounces. The high efficiencies offered by Synchro nous Drives make them ideal for many purposes.
No LubricationUnlike chain or gear drives, Synchronous Drives never need lubrication, since there is no metal-to-metal contact. Maintenance costs are cut to a minimum. Contamination from oil drip, spatter, splash or spray mist is eliminated, too. In addition, there is no oil or grease to trap dirt, grit or abrasive particles and accelerate wear. Food processors, grain elevator operators and other contamination-sensitive industries benefit especially from this feature.
High Tension EliminatedUnlike flat and V-belts, Synchronous Belts do not rely on friction for their pulling power. Slack-side tension is practically zero, and tight-side tension is reduced. As a result, overhung bearing loads are lessened with resultant improvements in motor and bearing life.
High Mechanical EfficiencySynchronous Drives have unusually high mechanical efficiency. Furthermore, transmission efficiency is not lost with use. The belt construction insures very little heat build-up since friction is not required to pull the load. In addition, belt tension is reduced. Significant power savings are thus obtainable, particularly when using Synchronous Belts on larger horsepower installations.
Economical OperationThe overall cost of Synchronous Drives can be lower than those of other drives. Original equipment costs are reduced by eliminating adjustable motor bases, lubricating systems and tensioning devices. Maintenance is simpler. No adjustments are needed due to stretch or wear. These savings are not confined to newly designed drives alone, because most roller chain drives can be con verted to Wood’s Synchronous Drives. Synchronous Belts are also ideal for areas where proper maintenance is difficult or where downtime could prove to be extremely expensive.

Synchronous Plus
Features And Benefits
Synchronous Plus belts are capable of operating at temperatures of -30˚F with no adverse effects.
Any time a belt is used in an elevated ambient temperature, the expected life will decrease. The relationship between ambient temperatures and belt life is shown in the chart below. As an example, at a temperature of 180˚F, we would expect life to be 60% of the life that would be obtained at 85˚F.
1. FIBERGLASS TENSION MEMBER FEATURE BENEFIT
Excellent Dimensional Less Maintenance Stability
No Stretch Retensioning Generally Under Load not Required
Allows for Small Pulley Economical Designs and Short Center Drives
2. MOLDED TEETH & BACKING FEATURE BENEFIT
Resists Damaging Longer Belt Life Environmental Factors
Outstanding Bending Smooth Belt Operation Characteristics
Superior Molding Smooth Surface Characteristics Reduces Vibration
3. IMPREGNATED NYLON WEAR JACKET
FEATURE BENEFIT
Durable Tooth Extends Belt Life Protection
Minimal Drag/ Smooth Precise Reduces Friction Operation

NOTE: Cast iron products can safely operate up to a maximum speed of 6500 feet per minute. For faster speeds MUST use ductile iron which has a maximum safe operating speed of 10,000 feet per minute.

Proper balance of rotating products is important for smooth, vibration-free operation. Standard balance of Wood’s stock products is a one plane balance. Depending on the face width, outside diameter, and operating speed a higher precision balance may be required for smooth operation. In those cases a two-plane balance is suggested.
Note: Two plane balance is for smooth operation only and DOES NOT increase the maximum safe operating speed of the product. Stock cast iron wheels may not exceed 6,550 feet per minute; and ductile iron wheels are limited to 10,000 FPM. (FPM = sheave outside diameter x RPM x .262)
The nomograph below may be used as a guideline to determine when two-plane balance is recommended. To use this chart lay a straight-edge between the diameter of the part on the left of the chart and the face width of the part on the right. The straight edge will intersect the slanted scale in the center of the chart. When the operating speed is greater than the intersection point a two-plane balance is recommended.
Example: If a 20 in. diameter x 10 in. (230 mm) face width sprocket runs faster than 1100 rpm, dynamic balancing is recommended.
