Rubber belt has the advantages in what respect?

Each kind of synchronous belt has its own advantages and disadvantages, some disadvantages also have no way to avoid, regardless of the new developed synchronous belt its performance has more powerful, it is developed on the basis of the original synchronous belt, though not perfect, but still a breakthrough.

Rubber belt, its characteristic mainly displays in the following aspects:

Rubber belt can reduce the transmission of shock and vibration, so has the advantages of low noise transmission, its no lubrication, can meet the demand of the high rotational speed transmission engine.

And the rubber belt is connected with the space is little, have a relatively good environmental adaptability. On many engines, especially on the v-type engines, because equipped with space is limited, need to use as little as possible transmission parts, and rubber belt to realize the function, such as: a rubber belt can be done at the same time the crankshaft drives of generator and steering booster pump and other accessories.

Understanding Trade-Offs When Selecting Drive Belt Systems

An additional trade-off is one that impacts the choice of V-belt or synchronous drive belt. In some applications, specifically systems such as fan or pump drives where loads are consistent and spikes are not common, it is being found that synchronous belt drives can be more efficient than V-belts. The positive engagement of the belt in the sprocket and the lower stretch of synchronous belts can mean a higher efficiency drive belt. So, the trade-off becomes the choice of a more expensive synchronous drive belt that will be more efficient compared to its less expensive V-belt equivalent.

As always, it is wise to discuss theses trade-off issues with your drive belt supplier. Application assistance and sales staffs are usually available to help frame these choices for your specific situation and to help you understand the trade-offs you might be making. Most drive belt suppliers have simple-to-use online selection programs that allow for the easy selection and comparison of multiple drive belt solutions.

How do you put a fan belt on?

For reasons we don’t quite understand, all the fan belts driven by the crankshaft seem to be called “fan belts.” In actuality, of course, the one driving the cooling fan (attached to the water pump) is the fan belt and all others should be called whatever they are driving, but that’s the way things have evolved. We’ll just call them “belts.”

Older cars generally had only one fan belt that drove the fan, water pump and generator. Later on another fan belt was added to drive a power steering pump and soon afterward another came along to run the air conditioner compressor. Whatever your engine/accessory configuration, changing fan belts is an easy and relatively straightforward, if not a dirty task. We’re going to change the alternator and A/C fan belts on this Corvette engine, partly because it’s been chewing up A/C fan belts and partly because it is clean enough to photograph details.

Every engine-driven accessory has some sort of adjustment on its bracket attaching points. In the case of this Corvette the alternator’s adjusting fastener is right at the top. The A/C compressor is adjusted with a bolt that passes through a flat plate on its front flange.

To loosen the fan belts you need to undo the adjusting bolts and push the device in towards the center of the engine. This can generally be done without loosening any other mounting hardware, but if the accessory is too tight you might have to do so. Just remember to count how many fasteners have been loosened so you won’t forget to re-tighten them all.

When should a timing belt be done on a car?

Replace the timing belt according at the mileage interval specified by the manufacturer

There is a major difference between a timing chain and timing belt. If the vehicle has a timing chain, there is no interval for changing it as a regular maintenance service procedure. However, if the vehicle has a timing belt, there is a very specific interval for replacing it. Timing belt replacement is generally recommended every 60,000 to more than 100,000 miles, depending on the vehicle manufacturer. Check ChiltonDIY’s maintenance schedules or the owner’s manual to determine the recommended service interval for your vehicle.

Why Does Regular Timing Belt Replacement Matter?

If the timing belt is not replaced when recommended, it can break. In the case of interference engines, which are manufactured with extremely close tolerances, a broken timing belt will cause the valves to hit the pistons, resulting in serious internal engine damage. Even if you do not have an interference-fit engine, a broken timing belt can leave you stranded, causing massive headaches and expensive engine damage.

How are the V belts specified?

V belts are NOT measured by diameter nor folding the v 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 v 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 v belts to obtain the correct width.

How To Identify the 3 Timing Belt Construction Types

We offer three types of timing belt construction, each for a different kind of application. Knowing what these three types are and how to identify them is the first step in specifying a belt for a new design or for placing a reorder on a replacement belt.

Timing Belt Construction Types: Each type is specified by a letter code.

Open-Ended “M” for linear drive applications
Spliced and Welded “V” for conveying applications
Truly Endless “BFX” for power transmission applications

Open-ended timing belts have a high spring rate and excellent tooth shear strength. If you are looking for a linear drive with stiffness and high repeatability, we recommend steel tension members over aramid fiber.

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 belts and they are available in most tooth configurations.

Truly endless code BFX polyurethane timing belts are extruded without a weld. This gives you the strongest belt construction type making it ideal for power transmission applications. They have steel tension members as a standard and are available in multiple material versions. The most popular tooth configuration is AT for more tooth shear strength. Double-sided BFX timing belts are also available for drive systems that change shaft direction. Custom lengths are available.
