Ease of installation and removal.
The original sheave and pulley installation program developed to facilitate installation and substitute of components.
The QD (Quick Detachable) design provides for both conventional (flange outboard) and invert (flange inboard) installation configurations.
1. Be sure the tapered cone surfaces of the bushing and the inside of the driven item are clean and free of anti-seize lubricants.
2. Slide QD bushing on shaft, flange end first. Assemble key.
3. Placement QD bushing on shaft. Tighten set screw over key “hand tight” with regular 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.
NOTE: Install M thru S bushings in the hub so that the two extra holes in the hub are located as far as feasible from the bushing’s noticed cut.
5. Tighten pull-up bolts alternately and evenly to tightness indicated in torque table on back. Usually do not make use of extensions on wrench handles. There should be a gap between your face of the sheave or sprocket hub and the flange of the QD bushing to insure a reasonable cone grasp and press fit.
CAUTION: THIS GAP MUST NOT BE CLOSED.
Use 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 greatly help provide easy installation and disassembly. A tapered bushing with directly edges uses an interior screw to greatly help drive the bushing in to the shaft, while a split taper includes a flange and a key on the bushing to greatly help provide more drive.
QD bushings (” and metric sizes) possess a flanged design and show a 4° taper with regular or reverse installation. They are stocked in popular completed bore sizes and minimal 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, uses a set screw to drive the bushing into the bore of the component becoming installed (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 on the outside of the bushing doesn’t necessarily mean it’s a QD style. Split Taper bushing also has a flange, and both are not interchangeable. The QD design includes a split that continues through the flange. The Steel QD (Quick Disconnect) Type bushing offers versatile and easy installation while providing exceptional holding power. QD Bushings are utilized considered the industry offering convenience and design flexibility. They are precision machined of quality Steel and are set up by tightening a number of 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 mounting of product in the conventional or invert positions. This allows cap screws to become installed through product hub or bushing flange whichever can be most convenient. A substantial benefit in installation, cap screws are constantly inserted from the exterior where they are often 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 qd bushing china pulleys where more clamping pressure 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.
