The initial sheave and pulley installation system developed to facilitate installation and replacement of components.
The QD (Quick Detachable) design offers 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. Placement QD bushing on shaft. Tighten set 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 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.
Notice: Install M thru S bushings in the hub to ensure that both extra holes in the hub can be found as far as possible 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 should be a gap between the face of the sheave or sprocket hub and the flange of the QD bushing to insure a satisfactory cone hold 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 transmission applications. Flanged quick-disconnect bushings feature a completely split design to help provide easy set up and disassembly. A tapered bushing with directly edges uses an interior screw to help drive the bushing in to the shaft, while a split taper includes a flange and a key on the bushing to help provide more drive.
QD bushings (inch and metric sizes) possess a flanged design and feature a 4° taper with regular or reverse mounting. They are stocked in popular completed bore sizes and minimum plain bore for custom reboring.
Many people refer 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 drive the bushing into 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 just. Also be aware that the looks of a flange on the outside of the bushing doesn’t indicate it’s a QD design. Split Taper bushing also has a flange, and the two are not interchangeable. The QD style has a split that continues through the flange. The Metal QD (Quick Disconnect) Type bushing offers flexible and easy set up while providing exceptional keeping power. QD Bushings are utilized considered the industry offering comfort and design flexibility. They are precision machined of quality Metal and are set up by tightening many cap screws. This draws the bushing into the taper bore of the merchandise which compresses the bore of the bushing. QD bushings are often removed utilizing the cap screws as jack-screws. Double drilled holes are furnished in QD Bushings permitting installation of product in the traditional or invert positions. This enables cap screws to be installed through product hub or bushing flange whichever is definitely most convenient. A significant benefit in installation, cap screws are usually inserted from the outside where they are easily accessible. QD Bushings can be found from stock with all popular bores within the range of each 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 power is required over standard bored-to-size bushings. Quick-Disconnect Bushings are crucial for installation v-belt drives, synchronous belt drives and roller chain drives.
