Introduction locking sleeve design principles with the drogue systems, most notably the "International" (International) and "Morse" (Holmes) both systems. The former is in diameter per foot taper length is 3.5 inches, the taper angle is 15 ° 48 ', non-self-locking ability, in the absence of mechanical force constraint, paired parts easily separated. Typical for Morse taper reaming cone drill or fixed to the machine axis fixture, which taper to change the length of 0.625 inches per inch diameter, cone angle of 2 ° 59 ', even in the lubrication conditions, this taper also remains self-locking capability. The principle advantage of taper parts fastened to the shaft, and its essence is the axial force into a radial force. This configuration produces a maximum clamping force application, while also easy to separate the parts, it just makes the best angle cone taking (8 °) to achieve their goals. Bushes and wheels with the force situation is like? When the axial force (F) forcing cone sleeve pushed when the pulley wheels, radial force (Ps) on the shaft and sleeve, sleeve and hub interface and (Ph), these pressures can reach 70-80N / mm2., at the wheel, put the cone drogue produce circumferential tensile stress and circumferential stress, its value up 160-190N / mm2., in supporting the pulley and sleeve design, with the pulley and the sleeve is determined sleeve shaft hole must be within the maximum permissible axle aperture. We have developed such a drogue pulley pulley factory direct products, totally let you rest assured that this is a relatively mature product, quality guarantee and perfect after-sales service, and technical support, we want 120% customer satisfaction! Guangzhou state Bushes hung assembly Note: 1, last cleaned before assembly must use petrol to ensure that all parts clean and dry, in order to ensure close cooperation with the surface and no oil, there is enough friction. 2, prior to assembly with hex bolt assembly also use gasoline wash and dry, not the bolt or screw holes in the coating of oil or grease to ensure there is enough after friction bolts self-locking capability. 3, within three hex bolts fastening turns need to be installed in place in order to ensure a uniform axial force by the sleeve pulley prices, ensure the pulley and sleeve coaxially positioned well. 4, pre-installation check the measurement assembly with hex bolt length to ensure that after the assembly bolts can withstand the drogue blind hole at the bottom, in order to ensure that the cone closely, and to ensure that the bottom of the blind hole bolt by reverse thrust, produce the same principle of double nut locking effect. 5, after fastening the cable pulley to check and adjust the master, the relative position of the driven pulley, ensuring two rounds in the same plane and the belt tensioner moderate. 6, the pulley cover should be in good condition and securely installed to ensure operation in a broken belt or pulley loose exits lead to major accidents. 7, the sleeve are wearing parts, after a long run pulley suppliers, bore and chain groove damage that may occur, should be checked before each assembly, spare parts found defective should be replaced.
