Ease of installation and removal.
The original sheave and pulley installation system developed to facilitate installation and replacement of components.
The QD (Quick Detachable) design provides for both conventional (flange outboard) and reverse (flange inboard) mounting configurations.
1. Be sure the tapered cone areas of the bushing and the within of the driven product are clean and free from anti-seize lubricants.
2. Slide QD bushing on shaft, flange end initial. Assemble key.
3. Position QD bushing on shaft. Tighten established screw over key “hand tight” with regular Allen wrench only. Do not use excessive force.
4. Slide huge end of sheave or sprocket taper bore into position over cone aligning drilled bolt holes in sheave or sprocket with tapped holes in flange of bushing. Assemble pull-up bolts and lock washers.
NOTE: Install M thru S bushings in the hub so that both extra holes in the hub are located as far as feasible from the bushing’s saw cut.
5. Tighten pull-up bolts alternately and evenly to tightness indicated in torque desk on back. Usually do not make use of extensions on wrench handles. There must be a gap between the face of the sheave or sprocket hub and the flange of the QD bushing to insure a reasonable cone hold and press fit.
CAUTION: THIS GAP SHOULD NOT BE CLOSED.
Use a tapered or QD bushing from Ever-Power with sheaves, pulleys, sprockets and many other power transmitting applications. Flanged quick-disconnect bushings include a completely split design to greatly help provide easy set up and disassembly. A tapered bushing with straight edges uses an interior screw to help drive the bushing into the shaft, while a split taper has a flange and a key on the bushing to help provide more drive.
QD bushings (inch and metric sizes) have a flanged design and show a 4° taper with conventional or reverse mounting. They are stocked in well-known finished bore sizes and minimum 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, runs on the set screw to operate a vehicle the bushing into the bore of the component being set up (sheave, sprocket, etc.). Be careful when installing these screws. The holes with threads on the bushing are for removal just. Also remember that the appearance of a flange on the outside of the bushing doesn’t necessarily mean it’s a QD style. Split Taper bushing also qd bushing china offers a flange, and both are not interchangeable. The QD design has a split that proceeds through the flange. The Steel QD (Quick Disconnect) Type bushing offers 
flexible and easy set up while providing exceptional holding power. QD Bushings are used thought out the industry offering comfort and design versatility. They are precision machined of quality Metal and are set up by tightening many cap screws. This draws the bushing in to the taper bore of the merchandise 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 installation of product in the traditional or reverse positions. This enables cap screws to be installed through item hub or bushing flange whichever is most convenient. A substantial benefit in set up, cap screws are usually inserted from the outside where they are easily accessible. QD Bushings can be found from share with all well-known bores within the number of every size bushing.
QD Bushings feature a split tapered flange with the split central to the flange and taper. They are used on sprockets, sheaves, and pulleys where more clamping push is required over standard bored-to-size bushings. Quick-Disconnect Bushings are crucial for mounting v-belt drives, synchronous belt drives and roller chain drives.
