Flat Rubber Drive Belts

Taizhou Tianou Rubber Co., Ltd. was founded in 2000, located in the eastern side of Tiantai National Scenic Area, has the reputation of "China Belt Industry City". Neighboring Shangshan Expressway, Yongtaiwen Expressway, 104 National Highway, the geographical location is superior, traffic is very convenient.

This rubber drive belts uses only flat belts and is passed over the driver and driven pulleys. The open and cross flat rubber drive belts are only possible with flat belts. The motion or power is transmitted from one shaft to another shaft by means of belts, i.e., these belts are used when the two shafts are apart at some distance. It consists of driver or driving pulley, driven or follower pulley, and the endless belt is passed over to these pulleys.

Rubber belts are uniform bands made of both natural and synthetic rubber and are widely used in various applications. Rubber Belts are available in various sizes and shapes and used for multitude of purposes. These belts include a wide range of rubber belts. Rubber belts can be classified as :

● Anti-static belts: They contain no static prone materials like carbon.
● Anti-vibration belts: They minimize vibrations in conveyor systems and the vibrations slowly abrade and stretch belts.
● Armored belts: They have crosswise insertions in the cover, made of materials like steel. This is to decrease tearing by sharp conveyed objects.
● Cable belts: They are reinforced with cables.
● Endless round belts: They are single piece belts. They are designed to stretch and do not require belt tension.
● Fin belts: They have fin-like structures which are protruded from the belts themselves. They are useful in applications such as catching containers and moving them into boxes.
● Multi-speed belts: They are used in variable speed applications such as automobiles and snowmobiles.
● Twisted belts: They are used to replace endless round belts that are damaged or destroyed.
● V-belts: They have a v-shaped profile having different variations of the v-belt.

These rubber belts have high strength, good flexibility and elasticity. These are used in factories, mines, docks, metallurgical industries, airports, irrigation equipment, power transmission equipment, wood cutting and in various other applications for industry and agriculture.

There are several types of flat belts, including:

Rubber Belts
Rubber flat belts were originally introduced as a replacement for leather belts but were replaced by V-belts due to mistracking and problems with high tension. However, recent technological developments in the manufacturing of flat belts have made them more practical and cost-effective. In addition, they have high elasticity and offer excellent grip, making them suitable for high-speed and heavy-duty applications.
The rise in the use of flat belts is due to their excellent efficiency and low bending loss from their thin cross-section and low creep. Additionally, flat belts have less wear than V-belts and come in widths to fit any application.

Timing Belts
Timing belts have rubber teeth on their inner side to provide a positive grip for precision timing and power transmission. They are used to maintain timing between components of mechanical systems and are essential for machine performance.
The materials used to manufacture timing belts include natural rubber and synthetic rubbers such as neoprene, polyurethane, and saturated nitrile. The rubber material is reinforced with cords to reduce the tendency of rubber to stretch and deform.
Unlike other flat belts, timing belts have teeth used to grip the pulleys of machines. The teeth have a trapezoidal or curvilinear shape to fit into the pulleys to which they are attached.

V-Belts
V-belts have a trapezoidal cross-sectional shape and are used to transmit power from driving components. Their design aims to avoid slippage and improve gripping, making them more dependable and efficient. In addition, the V-shape increases contact between the belt and pulleys it drives, making V-belts suitable for high-torque applications.
All V-belts are made of rubber with reinforcing cords to enhance their strength. In addition, to give V-belts increased durability and toughness, they are covered with a protective fabric or wrapped in rubber.

Poly-V Belts
Flat poly V-belts have multiple V-shaped ribs on their inner surface that mesh with pulley grooves to increase grip and reduce slippage. The ribs of a poly V-belt run along the full length of the belt longitudinally to make contact with the grooves of a pulley. As a result, the tension of a poly flat V-belt is evenly distributed over the width of the pulley.
The multiple ribs of poly V-belts reduce the thickness of the belt to give the belt greater flexibility and the ability to be wound tightly.

Wedgelock Belts
Wedgelock belts are a subset of V-belts with steeply angled walls to increase their load-bearing wedging capabilities. They have the typical trapezoidal shape with variations in their dimensions to meet their wedging capacity.
The design of wedgelock belts helps prevent slippage and improves power transmission efficiency. They are commonly used in heavy-duty applications, such as industrial machinery and power transmissions, and are made of various forms of rubber.

Fabric Ply Belts
Made with multiple layers of fabric material and designed for applications requiring heavy-duty strength and durability. The fabric layers are typically reinforced with synthetic materials such as polyester or nylon to increase resistance to stretching and wear.

Fabric Cord Belts
Similar to fabric ply belts, but made with a single layer of fabric material that is reinforced with cords. The cords provide additional strength and stability to the belt, making them ideal for applications requiring high-tension loads.

Synthetic Flat Belts
Made with synthetic materials such as polyurethane or silicone, synthetic flat belts are known for their durability, flexibility, and resistance to wear and abrasion. Synthetic flat belts are used in a variety of industrial applications, including packaging, food processing, and power transmission.
In general, the choice between fabric ply, fabric cord, and synthetic flat belts will depend on the specific application requirements and operating conditions, such as load capacity, temperature, and exposure to chemicals.

Raw Edge Belts
Raw edge belts are designed to provide maximum grip and prevent slippage, making them ideal for high-torque applications. They are typically made from a combination of synthetic rubber and reinforcing fibers and are available in a range of sizes and strengths.

Flat Wrapped Belts
Flat wrapped belts are similar to raw edge belts, but feature a wrapped construction that helps to provide additional stability and strength. This type of belt is often used in high-stress applications, such as power transmissions and industrial machinery.

Leather Belts
Leather belts were introduced during the first industrial revolution and were used through the end of the 19th and into the 20th century. They were replaced by flat rubber drive belts but are still used for some applications today and are available in one, two, or three ply. Leather belts have a smooth surface and are flexible, which makes them ideal for small diameter pulleys.

Belt Length: Belt length is the measure of the distance between the two pulleys and the distance around the circumference of the pulley. It is calculated using the following formula: Belt Length = 2π x Pulley Radius + 2 x Arc Length.

Pulley Diameter: The belt needs to fit the diameter of the pulley and its grooves properly. The diameter affects the belt length as specified by the manufacturer.

Center-to-Center Distance: The center-to-center distance is the distance between the centers of the pulleys and is part of the calculation of the belt length.

Operating Tension: The belt's width has to handle the load and provide sufficient grip on the pulley. The operating tension is the amount of tension needed to transmit the load and is used to determine belt width.

Load to be Transferred: The load to be transferred is used to determine the operating tension and the appropriate belt width.
Belt Speed: The speed at which the belt runs affects the operating tension and is typically specified by the manufacturer.
