Types of V-belts

Types of V-belts – main image

There are many types of V-belts, such as belts with chamfered sides, classic and cogged belts, and banded belts. Each type of this element is adapted to the specifics of the device, its load during operation and rotational speed. Below, we briefly characterize each of the popular types of this important component of belt transmissions.

Belt transmission and V-belt

What is a V-belt transmission? It is a type of mechanical transmission, which consists of two or more wheels belted with an elastic band (e.g. a V-belt). Belt transmissions are commonly installed in machines where they are responsible for transmitting power to receiving devices. They can be found in both simple and complex structures, and their role is certainly crucial to the operation of the entire machine.

V-belts, in turn, are components of belt transmissions. These are quite small elements, but their participation in the functioning of the entire structure is very important. They have a complex and layered structure and their role is to transmit power. In addition, they protect the entire system against overload, because they also act as a slip clutch.

Types of V-belts

V-belts are divided into many groups and subgroups depending on the criteria by which we look at them. For example, they can be classic and toothed, narrow-profile and wide-profile, or closed and open. Open V-belts are used when the construction does not allow the installation of a closed belt or when we have non-standard dimensions of the belt. Moreover, V-belts are divided into:

Toothed V-belts

Toothed V-belts are equipped with internal or external toothing, which increases the flexibility of the belt side surfaces. In this way, the belts are very strong and the internal friction in their compression layer is reduced. They work well with the pulley. The big advantage of toothed belts is the fact that they adhere better to the side surfaces of the groove and they do not need to be tightened as much as classic belts.

V-belts with bevelled sides and cover

The biggest advantage of V-belts with chamfered sides is low slip and higher transfer value compared to similarly sized covered belts. These are narrow-profile, toothed belts with internal passive toothing. They are perfect for working at high gear ratios and speeds.

Banded V-belts

These are several individual V-belts permanently connected to each other by a connecting tape. It is important that during their production only belts of the same length and size are joined together. Power bands are characterized by no slippage between V-belts and a better drive with horizontal axes. This type of drive element is also capable of transmitting shock loads. That is why they are installed in work vehicles, where they are responsible for transmitting the power of the combustion engine to receiving devices such as generators, starters, water pumps or fans.

Classic V-belts (normal profile)

Classic V-belts are commonly used in drives of industrial power machines (compressors and pumps). They are also used in machine tools such as grinders and lathes.

Multi-ribbed belts

Poly V-belts are a combination of V-belts and flat belts. They are mainly used in the gears of heavy goods vehicles, but also, for example, in household appliances. This is because multi-ribbed belts are capable of carrying very heavy loads and this at high rotational speeds.

Busik Po Bezdrożach - part III
Busik Po Bezdrożach - part III. We start our trip to the mountains with a walk around the stands to buy a map of Fogarasha. We manage to find one for 18RON, unfortunately, apart from the marked routes, there is nothing else, we were especially troubled by the lack of transition times, which were not even on the trail. Before leaving, I tried to find some information about the ascent of Moldoveanu. On one of the blogs I read that the trip back and forth takes about 3 days, google maps showed less than 4 hours, and rescuers at the shelter stated that it was about 10 hours of hiking, in one of the mountain magazines that Asia took with her they also wrote about a 3-day trip expedition, so we took this time. It's not a problem for us, we have tents and a rolling pin, you can go. However, we only had 2 days to reach the highest peak in Romania. The first ascent and the only signpost with the given time (1h) led to the pass above the shelter, the ascent was quite steep and rocky, sometimes very slippery, but as it was one of the attractions on the Transfogarska route, Sunday tourists climbing in white sneakers could not be missing there , bootki or flip-flops. I thought that such views are only with us. It took us about 30 minutes to get to the first hiking point. At the top, Dominika remembered that she had forgotten to take the tablets from the car without which she could not go any further. Well, it was late, not a long time, and a long way to go. I left my backpack and decided to go get it, because it will be faster this way. I treated myself to skyrunning training, I ran down the hill quite quickly, I took what I needed and I had to try again ... I turned the whole thing in 50 minutes. I felt my thighs and calves mercifully, what my heart loves, but Dominika's legs hated it: P Fortunately, as a reward at the top there was a chunk of bread with chocolate cream and a kiss. We threw the backpacks on our backs again and moved on. After a while all the tourists on Sunday disappeared and the trail became almost empty. We were surrounded by more and more beautiful views, but the trail was becoming more and more demanding, from steep, almost vertical descents to similar entrances, chains began to appear. There are no signposts, but only once in a while there is a trail marking that is faded from the sun or washed away by rain. Daniel wondered how Barry would manage in the mountains. However, Barry is not an ordinary mongrel, but rather a mountain goat mixed with a pooch. I have never seen (even in movies) that a dog could cope with the rocks so well, he would easily climb to Rysy, and Orla Perć would not be scary for him if he could enter the TPN; D.
