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

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

3V series six-groove taper bushed sheaves are manufactured 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 made to use a Q1, or R1 split-taper bushing, which we also stock. Most of our six-groove 3V split taper 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 V-Belt

(1) 3V-Series V-BeltsClassic 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) 3VX Cogged V-Belts3VX 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.

Related Split Taper Bushings

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. 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. 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".

How to Avoid the Problem of Over-tightening the Pulley?

Many customers are very trying in the process of disassembling the pulley, so the disassembly process is easy to damage the pulley, which is often caused by the over-tightening of the pulley, and the over-tightening of the pulley will easily affect the regular operation of the equipment, so how can we avoid the problem of over-tightening the pulley?To solve the problem that the shaft and the pulley are too tight, it is recommended to start from the following two aspects:1. Do not install the key first; use an emery cloth to remove the burrs and rust on the groove surface, use a file to repair the file when the burr is serious, and then install the pulley on the shaft without installing the key. Check the shaft diameter and wheel hole if it is very tight or cannot be installed. If the motor shaft is large, you can turn on the power to make the motor rotate and press it against the rotating shaft with an emery cloth (pay attention to safety), which is easy for repair electricians. Could you do it? In this way, the trimming will not produce an ellipse; it will save effort and then try to install it. Apply lubricating oil on the shaft each time you want to install it. The pulley can be pushed in by hand or lightly driven with a hammer, but it cannot feel loose.2. Measure the depth of the keyway. This dimension should be larger than the thickness of the key. Otherwise, the thickness of the key should be thinned until the gap between the key and the bottom of the wheel hub groove depends on the size of the shaft. Generally, 0.2~0.6mm (check the critical standard), put the key into the wheel hub, and it should be able to slide slightly loosely. If not, repair the burr or find the reason to fix it, then gently drive the key into the shaft groove with a hammer. The key needs to be replaced. And evenly apply lubricating oil on the pulley hole, shaft, and critical during assembly.

Usage Scenario of V-Belt Pulleys

The pulley drive can ease the impact of the load; the pulley drive runs smoothly, with low noise and low vibration; the pulley is mainly used for long-distance power transmission occasions, such as the power output of small diesel engines, agricultural vehicles, tractors, automobiles, mining machinery, machining equipment, Textile machinery, packaging machinery, lathes, forging machines, power transmission of some small horsepower motorcycles, power transmission of agricultural machinery, air compressors, reducers, reducers, generators, gins, etc.
