3V Series Cast Iron Double-Groove QD Sheaves for “3V” Belts

3V Series Cast Iron Double-Groove QD Sheaves for “3V” Belts

3V series double-groove QD (quick detachable) bushed sheaves(3V Series Double-Groove Sheaves) are working for 3V, 3VX, banded 3V. And banded 3VX belts. They range from 2.20″ to 25.00″ in diameter. Depending on the sheave size, they are made to use a JA, SH, SDS, SK, or SF QD bushing, which we also stock. Most of our double-groove 3V QD sheaves are manufactured from a high-strength grade 35 cast iron, are phosphate-coated, and are painted for anti-corrosion. All of them are balanced at the factory for smooth machinery operation.

Related 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 stand 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.

Related QD Bushings | Quick Disconnect 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.

Details to Pay Attention to when Replacing the Pulley

When the production equipment is used for a long time, its parts are inevitably worn out and must be replaced. Remove the locked screw with a suitable Allen wrench when replacing the European standard tapered sleeve pulley. Then, screw the removed screw into the disassembly hole to separate the pulley and the tapered sleeve. If the taper sleeve cannot be removed from the shaft, use a rubber tool to tap lightly to disengage the taper sleeve from the post. In addition to these, what details should be paid attention to when replacing the pulley?
Details to pay attention to when replacing the pulley:

1. When replacing the pulley, first ensure that the surface of the pulley is not damaged, and apply lubricating oil to the shaft hole so that the pulley can be removed more quickly so as not to affect the subsequent use;

2. When installing the tapered sleeve as a pulley, pay attention to the method of self-locking with screws, and it cannot be installed with other tools such as hammers.

3. Rotate the bolts out of the fastening holes, and then screw the bolts into the dismantling holes simultaneously. At this time, the bolts need to be forced at the same time. The pulley will fall off the tapered sleeve when the dismantling holes are stressed simultaneously. The work of removing the pulley is completed.

4. Put the pulley into the shaft, insert the tapered sleeve into the keyway of the post to adjust the position, send the pulley into the tapered sleeve, and then screw the bolts into the fastening holes. When the pulley is found to be offset, it can use the bolts into the disassembly hole for adjustment. When the adjustment is made, the installation of the pulley is completed. The keyway should be adequately tight in the groove of the shaft. If it is too fast or loose, it will damage the key and the track, and the belt will slip or vibrate if it is too loose. Therefore, contact the technician for verification immediately when selecting a model.
