8V Series Cast Iron Twelve-Groove Pulley Sheaves with Split Taper Bushings

8V Series Cast Iron Twelve-Groove Pulley Sheaves with Split Taper Bushings

8V series twelve-groove taper bushed sheaves are manufactured for 8V and 8V banded v-belts. They range from 12.5" to 64.0" in diameter. Depending on the sheave size, they are made to use U2 or W2 split-taper bushings, which we also stock. Most of our twelve-groove 8V 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 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". For additional information or to get a quote on our high-strength split taper bushings, please contact our customer support team, and we will be happy to assist you.

3 Ways to Avoid Pulley Vibration

Pulleys are commonly used transmission components in industrial machinery and equipment. During the operation of the pulley, it is often accompanied by vibration and even makes a sound, affecting the machine's life. If this vibration can be reduced, the device will become more durable.Three ways to reduce or avoid pulley vibration:1. Find a method from the source of production: we all know that the higher the concentricity of the pulley processing, the smoother the pulley rotation. Therefore, improving the machining accuracy can reduce the vibration amplitude when the pulley rotates. When the pulley leaves the factory, it must be checked for dynamic balance.2. Find the method from the design of the pulley: To avoid vibration when the pulley rotates, the belt groove and the shaft hole of the pulley are now divided into two parts, and the middle is filled with shock-absorbing rubber, and the shock-absorbing rubber is used to achieve the effect of shock absorption. This method is more practical and straightforward.3. Find the method from the installation process: when installing, check whether the engine and the pulley are firmly fixed, whether they are in a line, and whether the belt is adequately tight. These will have an impact on the operation of the pulley.

Inspection Knowledge of Pulley and Belt

First, check the tension of the pulley belt. At this time, you can use your thumb to press the strap between the two pulleys firmly. The pressing force is about 10kg. If the necessary amount of the belt is about 10mm, the belt tension is considered appropriate. If the reduction is too significant, it is believed that the pressure of the belt is insufficient. If the belt shows almost no reduction, it is considered that the belt tension is too high. When the stress is low, the v belt pulley and the belt are prone to slip.When the tension is too large, it is easy to damage the bearings of various auxiliary machines. To this end, the relevant adjustment nut or bolt should be loosened to adjust the belt's tension to an excellent state. The old belt is severely worn so that the contact area between the belt and the pulley is sharply reduced. At this time, as long as the belt is pressed hard, the pulley will sink deeply into the groove of the pulley. The rubber of the belt also has an aging problem. If the rubber of the belt is seriously aged, the new belt must be replaced in time.
