Relevant supporting D-series and D-series V-belt (1) D series V-belt Classic D-series V-belts have a top width of 1.25 inches, a thickness of 0.75 inches, and an angle of 40 °. In addition, the D V belt is one of the oldest V-belt types in the industry. Because of their long-term success and economic operation, they are also one of the most widely used belt series in the industry. The high-quality D-series v-belts we provide are manufactured according to ISO 9001 specifications, which are oil and heat resistant and can be directly interchanged with other brands. They are composed of natural rubber compound and polyester rope, and are covered with a mixture of cotton and polyester, with high durability.

(2) D series ribbon V-belt D series v-belts are part of the "classic" series of v-belts because they are one of the oldest styles used and one of the most common styles. Our belts are manufactured according to ARPM standards and have excellent strength, durability and performance. The top width of each belt (belt/rib) of D-series v-belt is 1-1/4 ".

Relevant QD sleeve | quick disconnect sleeve QD bushings are used in various sprockets, pulleys, pulleys and synchronous drives throughout the industrial power transmission and agricultural industries. They are designed for easy installation and unloading; They are also commonly referred to as quick disconnect bushings. The QD bushing facilitates normal installation on the outside of the flange and reverse installation on the inside of the flange, and utilizes a single split that extends over the entire length of the bushing. Our QD bushings can be interchanged with other brands and are made of high-grade steel by precision machining, which is suitable for perfect installation. Advantages of QD casing compared with different types of casing include:; Easy to install/unload, strong grip and excellent strength. We stock all standard size QD bushings and provide custom QD bushings upon request.

Correct installation procedure for pulley and conical sleeve 1. Remove the residual oil, paint and pollutants on the shaft, the inner hole of the tapered sleeve, the outer surface of the tapered sleeve and the surface of the tapered hole of the belt pulley, and remove the surface burrs. Note: The use of lubricant will cause the belt pulley to crack. Do not use any lubricant during installation. 2. Put the tapered sleeve into the tapered hole of the belt pulley, and align each hole (each complete hole is only half of the thread). 3. Add a little oil to the thread of the mounting screw, and then screw it into the half threaded hole of the pulley. Note: Do not lubricate the tapered surface of the tapered sleeve, the tapered surface of the hub, the bore of the tapered sleeve and the shaft. The use of lubricant can cause the pulley to break. 4. Install the key in the keyway of the shaft, install the tapered sleeve of the pulley on the shaft, and position it so that the pulley can move slightly axially when locked. Note: when installing the v-shaped belt pulley on the vertical shaft, precautions should be taken to prevent the pulley or cone from falling off during installation. 5. Tighten the mounting screws alternately until the tapered surface of the pulley and the tapered sleeve are completely assembled. NOTE: Do not use a worn hex wrench as it may cause loose assembly or damaged mounting screws. 6. Check the runout (swing) of the centering pulley; Correct if necessary. 7. Continue to tighten the mounting screws alternately to the recommended tightening torque of the mounting screws. Do not apply additional force after reaching the recommended tightening torque of the mounting screws. 8. In order to increase the clamping force of the taper sleeve, use a hammer to moderately knock the end face of the taper sleeve through the sizing block or sleeve. Note: Do not directly hit the conical sleeve with a hammer. 9. Tighten the taper sleeve mounting screws again after tapping. 10. Recheck the torque after the first test run and regularly check it later. If loose, repeat steps 5-9.
