The original sheave and pulley mounting system developed to facilitate installation and substitute of components.
The QD (Quick Detachable) design provides for both conventional (flange outboard) and invert (flange inboard) mounting configurations.
1. Be sure the tapered cone areas of the bushing and the inside of the driven product are clean and free of anti-seize lubricants.
2. Slide QD bushing on shaft, flange end 1st. Assemble key.
3. Position QD bushing on shaft. Tighten set 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.
Take note: Install M thru S bushings in the hub to ensure that both extra holes in the hub are located 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 use extensions on wrench handles. There should be a gap between the encounter 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.
Use a tapered or QD bushing from Ever-Power with sheaves, pulleys, sprockets and many other power transmitting applications. Flanged quick-disconnect bushings feature a completely split style to greatly help provide easy set up and disassembly. A tapered bushing with directly edges uses an internal screw to help drive the bushing into the shaft, while a split taper includes a flange and a key on the bushing to help provide more drive.
QD bushings (in . and metric sizes) possess a flanged style and feature a 4° taper with typical or reverse mounting. They are stocked in popular completed bore sizes and minimum plain bore for customized 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 becoming set up (sheave, sprocket, etc.). Be careful when installing these screws. The holes with threads on the bushing are for removal just. Also be aware that the appearance of a flange externally of the bushing doesn’t necessarily mean it’s a QD design. Split Taper bushing also has a flange, and the two aren’t interchangeable. The QD style includes a split that proceeds through the flange. The Metal QD (Quick Disconnect) Type bushing offers versatile and easy installation while providing exceptional keeping power. QD Bushings are used considered the industry offering comfort and design flexibility. They are precision machined of quality Steel and are set up by tightening several cap screws. This draws the bushing in to the taper bore of the product which compresses the bore of the bushing. QD bushings are often 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 reverse positions. This allows cap screws to become installed through product hub or bushing flange whichever can be most convenient. A substantial benefit in set up, cap screws are at all times inserted from the exterior where they are easily accessible. QD Bushings can be found from share with all popular bores within the number of every size bushing.
QD Bushings include a split tapered flange with the split central to the flange and taper. They are applied to sprockets, sheaves, and pulleys where more clamping drive is necessary over standard bored-to-size bushings. Quick-Disconnect Bushings are essential for installation v-belt drives, synchronous belt drives and roller chain drives.
