Types of transmission belts

There are many size and shapes belts used in transmission belt but today we are describe the mostly used belts.

According to the Shape:

1. Flat belt:

This belt is mostly used in the factories and workshops, where a moderate amount of power is to be transmitted, from one pulley to another when the two pulleys are not more than eight meters apart.

2. V- belt:

The V-belt is mostly used in the factories and workshops where a moderate amount of power is to be transmitted form one pulley to another, when the two pulleys are very near to each other.

3. Circular belt or rope:

The circular belt or rope is mostly used in the factories and workshops, where a great amount of power is to be transmitted, from one pulley to another, when the two pulleys are more than eight meters apart.

4. Timing belt or toothed belt:

These belts are used for power or motion transmission with accurate timing. These belts have toothed surface with meshed with the pulley so it is not a ordinary belt works on friction. This belts required special type of pulley so it is most expensive belt. This is used to obtain accurate timing.

Are all v belts the same?

How To Measure V Belts

Belts are NOT measured by diameter nor folding the belt in half. The most accurate way to measure the circumference of a v belt is with a v belt measuring tool or using a cloth tape measure (Not a steel tape measure or ruler). An additional option is to wrap a small diameter string/rope around the v belt, then measure the length of the string. When measuring be sure to have the v belt under slight tension and the cloth tape measure is tightly against the back of the v belt. Also, keep in mind belts do stretch and unfortunately there is no specific value for how much a v belt can stretch. You’ll also need to measure the width and depth to determine which section v belt you have.

How to determine the v belt number

All A,B,C,D,E,AX,BX belts list the inside circumference measurement after the letter of the v belt part number. Example: A88 has a 88″ inner circumference, then you add 2 inches for the A Section (Listed below) to obtain the outer circumference. If you measure the outer circumference, then you would subtract the number of inches based on the section you have (Listed below) to obtain the v belt number. This is also the same for the banded belts. Measure each individual band for banded belts to obtain the correct width.

How fractional & v belt numbers are coded

All sections 3L,3V,5V,8V,3VX,5VX v belts have the outside circumference after the number and letter(s). Example: v belt # 3V600 has a 60″ outside circumference. Inside circumference are not measured for these sections. This is also for the banded belts. Measure each individual band for banded belts to obtain the correct width.

What is application of V belt drive?

General

V belts are the workhorse within industry, available from virtually every distributor and adaptable to practically any drive. They are presently available in a wide variety of standard sizes and types, for transmitting almost any amount of load power.

Operation

Typically, v belts drives operate best at speeds between 1500 to 6000 ft/min ( 8 and 30 m/s). For standard belts, ideal peak capacity speed is approximately 4500 ft/min (23 m/s). Narrow v belts, however, will operate up to 10,000 ft/min (50 m/s).

Advantages

V belt drives permit large speed ratios and provide long life. They are easily installed and removed, quiet, and low maintenance.

How to Identify a BRECOflex Spliced and Welded V Timing Belt

Spliced and welded timing belts are used in many general purpose applications. They are the preferred construction type for conveying, as well as for welded profiles and backings. We are able to machine these timing belts and they are available in most tooth configurations.

  • A code “V” belt starts with a length of open roll stock that has finger splices cut into it and is then heat welded together
  • It has the same sealed edges and smooth back as open ended timing belts
  • Because it is welded, it had 50% of the strength of a truly endless timing belt
  • You can purchase “V” belts in one tooth increments from a minimum length.

Everything You Need To Know About V Belts

V belts are belts with a trapezoidal cross-section. Like other types of belts, they are used to transmit power or torque from the driving component to the driven component. Their design facilitates gripping onto the roller components (i.e., pulleys) during operation, decreasing the risk of slippage and increasing the consistency of the system’s output.

How Do V Belts Work?

The key components of a standard wrapped V belt are as follows:

  1. Base rubber compound. The rubber material forms the bulk of the V belt and acts as a shock absorber during operations.
  2. Tensile Members. Tensile members, commonly referred to as “cords” are embedded in the rubber, giving the V belt its strength and capability to transmit power.
  3. Protective covering. The textile cover guarantees the right grip for power transmission and protects the rubber from frictional damage and external contaminants.

Altogether, these components allow wrapped V belts to perform their function as intended—i.e., transmitting power and torque from one pulley to another by friction-based means.

Types of Conveyor Belts used for Industrial Purposes

A conveyor belt is an essential tool in the material handling sector. They are the continuous moving strips that are used for carrying different materials from one place to another. Mostly used for conveying a large volume of materials in a short span of time. A conveyor belt is also known as a belt conveyor.

Industrial Conveyor belt system

Industrial Conveyor belt system comprises of two or more pulleys. A continuous loop of transport stream the conveyor belt rotates about them. In order to move the belt and the material to transport one or both the pulleys should be power-driven.

These belts are generally made of rubber, PVC, Urethane, Neoprene, Nylon, Nitrile, Polyester, leather and others. The industrial conveyor belts are made up of multiple layers of material. Most of the material transporting belts comprise of two layers. The underneath layer is known as Carcass and it gives the linear strength and shape. The Carcass is made up of Polyester, nylon and cotton. The upper layer is known as the cover. Diverse variants of rubber or plastic compounds are utilised to make the cover.

Conveyor Belts that are used for Industrial Purposes:

Almost all of the manufacturers and suppliers were greatly dependent on the manpower before the emergence of industrial conveyor belts. The safety of the workforce and the quality of the product is a major issue under the manual handling of the products. In the current industry-driven scenario these rotating pulleys and belts are chosen for product handling.

Presently, a sophisticated technology is used in the Industrial Conveyor Belts over the simple belt conveyor systems. Advanced belts are opted based on their application by the industries. For instance, a simple metal belt would not be able to handle stones which could be precious or sensitive materials. Material handling Industries completely understand the types of conveyor belts. On the basis of their applications, they choose the safer, less time consuming, efficient belt conveyor systems as per their requirement.

The most widely used Industrial Conveyor Belts and their applications:

Solid, general-use belts:

These solid General use belts are commonly used in industries. They are made of rubber or a fabric such as nylon, polyester, neoprene, or nitrile. The primary applications of the belt can be determined by the properties of the belt. If we consider, mining and milling industries they commonly use rubber belts in handling the materials like raw ore and aggregates in a bulk quantity. Whereas, at the grocery stores, they make use of PVC conveyor belts and at the Airports belts made of Neoprene, polyester, or rubber are used for handling baggage.

Filter belts:

In order, to drain out the excess liquid or toxins, Water treatment industries commonly use these Filter belts which permit the particles to pass through a filter instead of being carried by the conveyor system.

Woven metal belts:

These belts are mainly used in industries which deal with cooling, drying and heating processes in the sectors like food manufacturing, electronics and glass – manufacturing industries. These belts are made of interlinked chains or wiring to facilitate the flow of air while the product is carried.

Hinged belts:

The Industries which handle scrap and various small products for recycling mainly make use of these hinged belts. These belts are made of metal. These belts provide a flat, solid surface which rotates around the pulley by means of the interlocking hinges. These belts are very sturdy and can be used rigorously.

Plastic interlocking belts:

These are mainly used in food packaging industries and in the automotive sector. These belts are suitable for environments where there would be regular cleaning and belt change. These Plastic belts are the perfect substitute for fabric and metal belts.
