The initial sheave and pulley mounting program 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 inside of the driven item are clean and free from anti-seize lubricants.
2. Slide QD bushing on shaft, flange end 1st. Assemble key.
3. Placement QD bushing on shaft. Tighten set screw over key “hand tight” with regular Allen wrench only. Usually 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 to ensure that both 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 desk on back. Usually do not use extensions on wrench handles. There must be a gap between your encounter of the sheave or sprocket hub and the flange of the QD bushing to insure a reasonable cone grip and press fit.
CAUTION: THIS GAP MUST NOT BE CLOSED.
Use a tapered or QD bushing from Ever-Power with sheaves, pulleys, sprockets and several other power transmission applications. Flanged quick-disconnect bushings feature 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 includes a flange and a key on the bushing to help provide more drive.
QD bushings (” and metric sizes) have a flanged design and show a 4° taper with regular or reverse mounting. They are stocked in well-known finished bore sizes and minimum plain bore for customized reboring.
Many qd bushing china 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 in to the bore of the component being installed (sheave, sprocket, etc.). Be cautious when installing 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 offers a flange, and both aren’t interchangeable. The QD style has 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 convenience and design versatility. They are precision machined of quality Metal and are installed by tightening several 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. Dual drilled holes are furnished in QD Bushings permitting installation of product in the conventional or invert positions. This enables cap screws to end up being installed through product hub or bushing flange whichever is definitely most convenient. A substantial benefit in set up, cap screws are often inserted from the outside where they are often accessible. QD Bushings can be found from stock with all popular bores within the number of each 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 push is necessary over standard bored-to-size bushings. Quick-Disconnect Bushings are crucial for installation v-belt drives, synchronous belt drives and roller chain drives.
