Une courroie trapézoïdale lisse est un élément de transmission de puissanceutilisé dans de nombreux systèmes mécaniques. Elle est fabriquée à partir d'un caoutchouc synthétique, le polybutadiène, et présente une section transversale trapézoïdale en forme de V. Cette forme permet à la courroie d'épouser la gorge correspondante de la poulie.
A smooth V-belt is a power transmission element used in many mechanical systems. It is made from a synthetic rubber, polybutadiene, and has a V-shaped trapezoidal cross-section. This shape enables the belt to fit into the corresponding groove on the pulley.
The advantage of using a smooth V-belt is that it offers durable, low-maintenance and quiet power transmission. It is also efficient for applications requiring high efficiency. What's more, smooth V-belts are relatively easy to install. It is known for its excellent resistance to oil and heat, and requires no lubrication.
Where and when are they used?
Smooth V-belts are used in many fields and applications where power transmission is required. Here are just a few examples of where smooth V-belts are commonly used:
Industrial machines: they transmit power between different components such as electric motors, pumps, compressors, fans, conveyors, etc.
Household appliances: smooth V-belts are also used in household appliances such as washing machines, tumble dryers and lawnmowers to drive drums, blades, etc.
Agricultural equipment: smooth V-belts are used in agricultural equipment such as combines, tractors, balers and sprayers to transmit power to the various components.
Machine tools: in the manufacturing industry, smooth V-belts are used in machine tools to drive spindles, work tables, cutting tools and so on.
What are the different types of smooth V-belts?
V-belts are designed for flexibility, easy installation and maintenance. They enable efficient transmission and are suitable for many applications thanks to their wide range of sizes. Below is a non-exhaustive list of smooth V-belt sections:
Z: Z smooth V-belts have a cross-section of 10 mm wide by 6 mm high. A: A smooth V-belts have a cross-section 13 mm wide by 8 mm high. B: Smooth V-belts B have a cross-section 17 mm wide by 11 mm high. C: C smooth V-belts have a cross-section 22 mm wide by 14 mm high. SPZ: SPZ smooth V-belts have a cross-section of 9.7 mm wide by 8 mm high. SPA: SPA smooth V-belts have a cross-section 12.7 mm wide by 10 mm high. SPB: SPB smooth V-belts have a cross-section 16.3 mm wide by 13 mm high. SPC: SPC smooth V-belts have a cross-section 22 mm wide by 18 mm high. 3V: 9 mm wide by 8 mm high. 5V: 15 mm wide by 13 mm high. 8V: 25 mm wide by 23 mm high. 3L: 3L smooth V-belts have a cross-section of 9.5 mm wide by 6 mm high. 4L: 4L smooth V-belts have a cross-section of 12.7 mm wide by 9 mm high. 5L: 5L smooth V-belts have a cross-section of 15.8 mm wide by 9.5 mm high.
How to choose a smooth V-belt?
When looking for a smooth V-belt, we always recommend using the same belt as the original. To do this, you'll need to know its reference number and/or dimensions. The part number is usually written on the belt, if it's not too damaged. If not, you'll need to determine the type of belt you need. Is it a trapezoidal belt? Is it smooth or toothed? Once you have the answers to these questions, you'll need to determine the desired cross-section (height x width), as well as its inside or outside length.
