Trapezoidal (V-belt) pulleys

What are trapezoidal or V-belt pulleys for?

The trapezoidal or V-belt pulleys are intended for high-power industrial transmission, and are characterised by their ability to retain their function of sacrificial part.

Trapezoidal (V-belt) pulley sections

Emiliana Cuscinetti produces different models of trapezoidal (V-belt) pulleys to cater for all needs. The available sections are Z-SPZ- A-SPA- B-SPB- C-SPC. The pulley bodies range from 1 to 10 grooves, and have diameters up to 1250mm. V-belt pulleys are also available in a taper bushing, cast iron version.

Toothed belts

The toothed belts stand out as modern and versatile products within the field of industrial transmissions. The motion is transfered from the pulley to the belt and vice versa, without slippage and in perfect synchronism.

Furthermore, the sturdy structure of the toothed belts is particularly suited to high-power transmissions and low-speed, high torque. Finally, they do not require strong initial tensioning, thus avoiding the overload of their supports.

Advantages

The main advantages of using toothed belts include their low-noise, high-performing operation, as well as their compact size and low-maintenance requirements

Finally, the quality of a synchronous transmission depends on both the belt and the pulley: Emiliana Cuscinetti selects the best brands to ensure a perfect fit between the two elements.

Toothed pulleys

The toothed pulleys are fundamental elements in synchronous industrial transmissions because, together with the toothed belts, they are among the most economical solutions for high-power transmission, and ensure synchronous motion.

The pulleys consist of a disk that rotates around its axis, and grooves to locate cables, belts, ropes or chains.

Applications

Toothed pulleys are used in a wide array sectors, including:

• machinery, gearboxes, engines;
• lifts;
• funiculars, cable cars and cableways.

Sprockets

What are industrial sprockets for?

Industrial transmissions are characterised by excellent technical performance applied to the transmission of rotary motion, such as in bicycles or cars, and linear motion, such as in belts and machine tools.

Industrial sprockets are single toothed wheels; alternatively, they are the smallest components of the crown-pinion system: in this last case the teeth mesh with a transmission chain or other types of perforated elements.

Emiliana Cuscinetti has a wide assortment of chain sprockets, in compliance with the main Standards and the most recent International Standards of Unification.

Crowns

What are industrial crowns and what are they for?

Crowns are part of industrial transmissions and can be single toothed wheels or the largest components in the crown-pinion system.

Their function is to mesh with a transmission chain or other gears to help transfer rotary motion, such as in bicycles, or linear motion, as in the case of tapes, or tools and equipment.

Features

Depending on the type of application, industrial crowns can be made of the following materials:

• plastic for high-power transmission;
• Strong metals and alloys, such as steel, for their long life;
• light metals, such as ergal, for shorter duration;
• combination of metals and alloys to combine lightweight and strength together.

Pack and Pinion Systems

Among the various types of industrial transmissions, the rack and pinion systems are renowned for their high degree of efficiency, which makes them suitable for axial forces of great magnitude. Emiliana Cuscinetti supplies high-quality, reliable and wear-resistant rack and pinion systems.

Features

The rack and pinion systems are linear gears which, together with a toothed wheel, convert rotary motion into continuous linear motion and vice versa.

Depending on the customer's need, knurled and ground toothing can be used, as well as and different materials depending on the applied load.

Applications

The rack and pinion systems can be applied to a wide array of industrial sectors, such as the mechanical one, but their most common application is in the transport sector: examples of that are the railway transmission systems or car steering systems. The rack and pinion systems are also used in roller coasters in amusement parks.

Industrial chains

Advantages

Among the many advantages of industrial chain drives, high-performance and efficiency are achieved thanks to the low level of wear on the chains. This makes them particularly long-lasting, with a chain lasting up to 4 or 5 years.

Industrial chains are the most suitable solutions in case a perfect synchronicity is required: the teeth which operate simultaneously guarantee an excellent fluidity of movements.

Thanks to high precision components, industrial chains take up less space and make less noise than other types of industrial transmissions, while guaranteeing the transfer of the same amount of power.

Applications

Industrial chains find application in a number of industrial sectors, including:

• agriculture;
• aviation;
• food;
• construction;
• timber;
• ceramics;
• chemical industry
• machine tools;
• …
