3V Series Cast Iron Three-Groove Sheaves with Split Taper Bushings

3V Series Cast Iron Three-Groove Sheaves with Split Taper Bushings

3V series three-groove taper bushed sheaves(3V Series Three-Groove Sheaves) are making for 3V, 3VX, banded 3V, and banded 3VX belts. They range from 2.65″ to 33.50″ in diameter. Depending on the sheave size, they are making to use G, H, P1, Q1, or R1 split-taper bushings, which we also in stock. Most of our three-groove 3V split taper sheaves are making from a high-strength grade 35 cast iron, and with phosphate-coating, and painting for anti-corrosion. Balanced at the factory for smooth machinery operation.

How to choose the Right 3V Belt Pulleys and V-Belt?

A 3V Belt Pulley is a mechanical pulley for rotating a 3V belt. These pulleys are also known as V-belt pulleys and are often placed side-by-side. A single pulley may feature multiple grooves around its circumference. When used in multiple-belt drives, the torque is distributed over several belts, providing mechanical redundancy.

Belt drives have several advantages over other mechanical drives. For example, they can provide opposite rotation without a gearing system. They are also easier to maintain and are cleaner than different drive types. They are also more flexible and do not require oil or grease to function. These advantages make them more affordable than other drive types.

When choosing a 3V Belt Pulley, you must understand how the cross-section works. The cross-section of a V-Belt is generally described as a trapezium with parallel top and bottom sides. The pitch line, the distance between the top and bottom sides, and the inside and outside lengths are all critical. Understanding these features will ensure you choose the right size for your application.

Matching 3V, 3VX Series V-Belt

(1) 3V-Series V-Belts

Classic 3V-Series V-Belts have a 0.38″ top-width, 0.31″ thickness, and a 38° angle, which also classifies them as a deep-wedge v-belt. 3V series belts are designed to be more compact with more drive capability than the standard 40° angle v-belts. Because of their long-term success and economical operation, they are also one of the industry’s most widely used belt series. The premium 3V-series v-belts we supply are manufactured under ISO 9001 specifications and ARPM Standards; they are oil and heat-resistant and directly interchange with other brands. 3V belts are constructed of a natural rubber compound with polyester cords and use cotton with a polyester blend cover for high durability. 3V series belts are used in most general heavy-duty industrial applications along with Heating, ventilation, air conditioning (HVAC), lawn and garden equipment, and agricultural equipment. We also stock a complete line of high-power v-belts and accompanying v-belt pulleys/ sheaves.

(2) 3V-Series Banded V-Belts

3V-series v-belts are a part of the “classic” lineup of v-belts because they are one of the oldest style belts used and one of the most common. Our belts are manufactured following ARPM standards and offer superior strength, durability, and performance. 3V-series v-belts have a 0.38″ top-width per belt (band/ rib).

(3) 3VX Cogged V-Belts

3VX cogged v-belts are designated by having a 0.38″ top-width and 0.31″ thickness. Our cogged 3VX v-belts are manufactured with raw-edge sidewalls to eliminate slippage and increase efficacy, saving operation costs. They are also manufactured by ARPM standards and are oil and heat-resistant. 3VX belts are constructed from a high-quality chloroprene compound with high-strength polyester chords and have a top fabric built from a cotton polyester blend. Besides the performance, durability, and energy savings benefits, our cogged v-belts will work with existing stand pulleys/ sheaves. Please contact us to get a quote on 3VX cogged v-belts or pulleys, and we will be happy to assist you.

(4) 3VX Banded Cogged V-Belts

All of our v-belts are according to ARPM specifications and offer superior performance and durability. Due to their design, banded 3VX cogged v-belts run smoother, more relaxed, and typically outlast a standard banded C v-belt. They also offer a higher efficiency than ordinary banded v-belts, which means fewer energy costs.

Accessories Split Taper Bushings

Split taper bushings are amongst the most common bushings utilized due to their high integral strength, simplicity of installation and uninstall, and high holding power for successfully coupling a shaft onto a drive or idler component. Split taper bushings are utilized in a broad range of sheaves, conveyor pulleys, and sprockets. Our high-quality split taper bushings are manufactured from high-grade steel or cast and interchange with any other brand, designed as a flanged bushing with a tapered barrel attached that contains one slit on each side. We stock split taper bushings ranging from the G-series to W2-series and in inch and metric bore sizes that range from 0.375″ up to 7.438″.

The Working Principle and Characteristics of the Pulley

The working principle of the pulley is that a belt connects the driving pulley and the driven pulley, and the power is driven by the friction force generated by the friction between the pulley and the belt. The pulley drive runs smoothly, with low noise, slight vibration, a simple structure, and convenient maintenance. The disadvantage is that it is difficult to install, prone to slippage after prolonged use, and the transmission efficiency cannot be guaranteed.

The taper sleeve pulley is a new type of pulley widely used in European and American countries. It consists of two parts. A tapered sleeve is connected between the pulley and the installation shaft, and then it is locked with an Allen wrench to fix the screw, and it can be used. This kind of pulley solves the problem of complex installation of traditional pulleys. It does not need external force as before. Pullers, hammers, and other items only need an Allen wrench to complete the installation. After installation and use, even if the pulley is worn and slipping, It does not need to replace the entire pulley at the same time, and it only needs to replace one installation taper sleeve to continue to use, which can significantly reduce the use cost.
