Matching 3V, 3VX Series V-Belt

(1) 3V-Series Deep Wedge 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 along with the accompanying v-belt pulleys/ sheaves.

(2) 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 v-belt pulleys/ sheaves.

(3) 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 by ARPM standards and offer superior strength, durability, and performance. 3V-series v-belts have a 0.38" top-width per belt (band/ rib).

(4) 3VX Banded Cogged V-Belts

All our v-belts are manufactured by ARPM specifications and offer superior performance and durability. All our v-belts are manufactured by ARPM specifications and provide excellent 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 QD Bushings

QD bushings are utilized throughout the industrial power transmission and agricultural industry for various sprockets, sheaves, pulleys, and synchronized drives. They are designed for easy installation and easy uninstallation; they are also commonly referred to as quick-disconnect bushings. QD bushings can help conventional mounting with the flange outboard and reverse mounting to where the flange is inboard and utilize a single split that extends through the entire bushing length. Our QD bushings interchange with other brands and are made from high-grade steel precision machined for perfect application fitment. QD bushings' benefits over different styles include; ease of installation/ uninstall, superior holding power, and extreme strengths. We stock all the standard sizes of QD bushings and supply custom QD bushings upon request, including stainless steel ones. QD bushings are found in some of the most rugged applications worldwide; contact our customer service team today for a quote or additional information on our premium QD bushings.

7 Things That Should Be Paid Attention in the Assembly of Tapered Sleeve Pulley

Taper-sleeve pulley is a new mechanical transmission connecting component commonly used in European and American countries. The 8-degree outer tapered surface is tightly connected with the inner tapered surface of the pulley, significantly improving the centering accuracy of the transmission parts. Taper sleeve size is a standard series design. Its internal hole keyway is processed according to ISO standards. The versatility and interchangeability are excellent and suitable for various occasions. The inner hole and the chain groove may be damaged when the transmission parts run for a long time. Taper sleeves of the exact specification can be used again. Therefore, the service life of the transmission parts is greatly improved, the maintenance cost is reduced, and time is saved.

1. Before and after the pulley assembly, gasoline must be used to ensure that all parts are clean and dry to ensure that the mating surface is tightly matched without oil stains and has sufficient friction.

2. The hexagon socket head cap bolts for assembly should also be washed with gasoline and dried before assembly. Do not apply lubricating oil or grease in the bolts or screw holes to ensure sufficient frictional self-locking ability after the bolts are fastened.

3. When the three hexagon socket head bolts are about to be installed, they need to be tightened in turns to ensure that the tapered sleeve is subjected to uniform axial force and that the pulley and the tapered sleeve are well positioned coaxially.

4. Check and measure the length of the hexagonal socket head bolts for assembly before installation to ensure that the assembly bolts can withstand the bottom end of the blind hole of the taper sleeve after tightening to ensure that the tapered surface fits tightly and to ensure that the bolts are subjected to the reverse thrust at the bottom of the blind hole, resulting in The anti-loosening effect of the double nut principle is the same.

5. After the pulley is tightened, check and adjust the relative position of the primary and driven pulley by pulling the wire to ensure that the two pulleys are on the same plane and the belt tension is moderate.

6. The pulley cover should be intact and installed firmly to ensure that the belt is broken or the pulley is loosened and withdrawn during operation, resulting in a significant safety accident.

7. The tapered sleeve is a vulnerable part. It should be checked before each assembly, and the spare parts should be replaced in time if any defects are found. After a long operation, the inner hole and the chain groove may be damaged.
