The original sheave and pulley mounting program developed to facilitate installation and substitute of components.
The QD (Quick Detachable) design offers both conventional (flange outboard) and invert (flange inboard) installation configurations.
1. Be certain the tapered cone surfaces of the bushing and the within of the driven product are clean and free of anti-seize lubricants.
2. Slide QD bushing on shaft, flange end first. Assemble key.
3. Position QD bushing on shaft. Tighten qd bushing china arranged screw over key “hands tight” with standard Allen wrench only. Do not use excessive force.
4. Slide large end of sheave or sprocket taper bore into placement over cone aligning drilled bolt holes in sheave or sprocket with tapped holes in flange of bushing. Assemble pull-up bolts and lock washers.
Notice: Install M thru S bushings in the hub so that the two extra holes in the hub can be found as far as possible from the bushing’s noticed cut.
5. Tighten pull-up bolts alternately and evenly to tightness indicated in torque table on back. Do not make use of extensions on wrench handles. There must be a gap between the encounter of the sheave or sprocket hub and the flange of the QD bushing to insure a satisfactory cone grasp and press fit.
CAUTION: THIS GAP SHOULD NOT BE CLOSED.
Make use of a tapered or QD bushing from Ever-Power with sheaves, pulleys, sprockets and many other power tranny applications. Flanged quick-disconnect bushings include a completely split style to greatly help provide easy installation and disassembly. A tapered bushing with directly edges uses an internal screw to greatly help drive the bushing in to the shaft, while a split taper has a flange and an integral on the bushing to greatly help provide more drive.
QD bushings (inch and metric sizes) possess a flanged style and feature a 4° taper with standard or reverse installation. They are stocked in popular completed bore sizes and minimal plain bore for custom reboring.
Many people make reference to both types as a “taper lock” because they both use the tapered wedging action to lock to the shaft. The taper bushing, with it’s straight sides, uses a set screw to operate a vehicle the bushing in to the bore of the component getting set up (sheave, sprocket, etc.). Be careful when setting up these screws. The holes with threads on the bushing are for removal only. Also remember that the appearance of a flange on the outside of the bushing doesn’t indicate it’s a QD style. Split Taper bushing also offers a flange, and the two are not interchangeable. The QD design includes a split that continues through the flange. The Metal QD (Quick Disconnect) Type bushing offers flexible and easy installation while providing exceptional keeping power. QD Bushings are utilized thought out the industry offering convenience and design flexibility. They are precision machined of quality Steel and are set up by tightening many cap screws. This draws the bushing in to the taper bore of the product which compresses the bore of the bushing. QD bushings are easily removed by using the cap screws as jack-screws. Double drilled holes are furnished in QD Bushings permitting mounting of product in the traditional or invert positions. This allows cap screws to end up being installed through item hub or bushing flange whichever is certainly most convenient. A significant benefit in installation, cap screws are constantly inserted from the outside where they are often accessible. QD Bushings can be found from share with all well-known bores within the range of each size bushing.
QD Bushings include a split tapered flange with the split central to the flange and taper. They are used on sprockets, sheaves, and pulleys where more clamping pressure is necessary over standard bored-to-size bushings. Quick-Disconnect Bushings are essential for mounting v-belt drives, synchronous belt drives and roller chain drives.
