How To Care For Your Car: Timing Belt

A timing belt is a rubber belt with teeth that helps the engine operate smoothly by linking the camshaft(s) and crankshaft. The camshaft is a spinning shaft that helps with the proper timing of the valves inside the engine to open and close. Meanwhile, the crankshaft helps the pistons move up and down. Connecting the camshaft to the crankshaft with a belt keeps the two assemblies in sync. That way, the valves open and close at the correct time.

It’s worth noting that not all cars have a timing belt. Some have a timing chain (or in rare cases, a set of gears) instead.

How does it break?

The timing belt breaks most often due to lack of maintenance. The timing belt will wear and tear over time because it is made of rubber. When the engine is extremely hot, it causes the belt to naturally lose its strength and texture which results in a snapped belt. As such, the timing belt should be replaced in accordance with the manufacturer’s recommended service schedule. The information is outlined in your car’s owner’s manual.

Another reason for breakage is water pump seizing, which is caused by a lack of coolant system maintenance. When the water pump seizes, it causes the gears to instantaneously come to a halt which will automatically cause the belt to snap.

The timing belt can become more expensive if it is not replaced. If the timing belt snaps, the vehicle will have to be towed. The results of a snapped timing belt can cost thousands of dollars. Also, the valves can bend and ruin the engine, which can result in engine replacement.

It’s highly recommend to have your timing belt replaced by a professional technician or mechanic. Proper tools, skills and knowledge are needed. If the replacement is not done properly and the timing is off on the vehicle, it can result in engine damage and be more expensive in the future. The timing belt cannot be replaced with alternatives.

How to Quiet a Noisy Fan Belt

Most modern vehicles come equipped with serpentine belts, though they may occasionally be called fan belts. Older vehicles may have belts that are used only to power the fans that cool the radiator. These belts are very similar and may be treated in the same fashion. A noisy fan or serpentine belt can make chirping, squeaking or squealing sounds that may be consistent or may come and go. Often, these sounds indicate an issue that may need to be resolved like a loose or damaged belt.

1. Ensure your vehicle is equipped with a neoprene belt. Most modern vehicles have a serpentine belt instead of a fan belt, though the names may be used interchangeably. Older model vehicles and some high-performance applications still utilize fan belts instead of electric fans. Older belts were made of neoprene and would benefit from the application of belt dressing, but newer EPDM-made belts may dry out as a result of using belt dressing.

2. Open the hood. You will need to apply the belt dressing directly onto the belt. In order to do so, you will need to open the hood of the vehicle and remove any cowl cover that may be in place over the fan belt itself. This may require the use of some basic hand tools like a socket or hand wrench.

3. Locate the fan belt. The fan belt will likely be located at the front of the engine, attached to a pulley that rotates the cooling fan or fans for the radiator. It will often be black or grey. You may be able to locate it faster by starting at the radiator fan and working backward.

4. Start the vehicle. Ensure the vehicle is in park with the parking brake engaged, then start the engine. You will need the engine to be running in order to apply the belt dressing evenly over the entire length of the belt.

5. Spray the belt dressing directly onto the belt. With the engine running, spray the belt dressing directly onto the back of the fan belt. As the engine runs, the fan belt will be moving quickly, so you can leave the can in one place and spray onto the belt as it spins.

Rubber Conveyor Belt Structure

Rubber conveyor belts are used to carry products continually at some distance or range and usually offer the most comfortable and economic advantages in the transportation of products.

The rubber conveyor belt has been used for long years in lot of industrial areas, from the escalator in the shop and metro, to all types of sectors, such as coal and ore, transport of materials in the concrete industry and half-finished products and unloading at the ports, at the railway station and the warehouse.

In order to offer the finest rubber conveyor belt appropriate for these sectors and to meet clients, we offer different products categorized by type of carcass, fabric inserts, cover rubber, implementation and design.

The basic design of the rubber conveyor belt generally consists of different types of cover rubber, insert – called carcass, reinforced fabric – usually polyester or nylon and adhesive rubber or steel cords.

1. Cover rubber. The conveyor belt’s top layer usually is made of natural or synthetic rubber, and is called cover rubber which protects the carcass. It has abrasion, temperature, petroleum, chemical, static and fire-resistant characteristics and depends on the working conditions.

The top cover of the rubber conveyor belt can be modified depending on the requirements and be Abrasion Resistant, Cut Resistant, Heat, Oil, Cold Resistant, Flame Resistant, or offerEnergy Saving Compounds.

2. Carcass. Maintains the tension of the rubber conveyor belts and supports the transported products. The carcass of the rubber conveyor belt usually is made of excellent bonded rubber using coated cloth, nylon, polyester, steel wire or aramid. Carcass can be made of Steel Cord, NN (Nylon-Nylon), EP (Poliester-Nylon), SW (Straight Warp), Aramid fibers or other materials

3. Adhesive Rubber. Maintains the adhesive power between all layers of carcass and the cover rubber and keeps their durable flexibility and tension.

4. Reinforced cover. It is used to protect the carcass in case that the products are larger or a tear occurs because significantly shaken in worse working conditions than specified, putting excess load on the top cover and carcass.

Choosing the right transmission belt

Belts are mechanical elements used for power transmission without phase shift. They are loops of flexible materials used to mechanically connect several rotating shafts, most often parallel. Belts can be used as a transmission element, to efficiently transmit power or movement.

How to choose a transmission belt?

In order to make the right choice, you will need to know the type of section and the belt dimensions. In this guide you will find the different sections available on the market, with their advantages and disadvantages.

Why choose a flat belt?

As in any transmission belt system, the flat belt allows a mechanical force to be transmitted from one pulley to another. Flat belts offer an optimal efficiency of 98%; however, they are only suitable for low loads. Once the drive system is aligned, flat belts can be self-centered by curved pulleys. This type of belt is used in many power transmission applications.

Why choose a V-belt?

These are the most commonly used belts for power transmission. At the same level of tension, they transmit higher power than flat belts. They are used, for example, in variable-speed drives. They offer the best combinations of traction, speed, bearing load and service life.

Why choose a ribbed belt?

As its name suggests, this kind of belt is ribbed lengthwise, which greatly increases the contact surface between the pulley and the belt. It works by adhering the ridge part of the belt to the pulley. Its one-piece structure allows for homogeneous distribution of the belt tension on the pulley’s contact surface.
