The original sheave and pulley installation system developed to facilitate installation and alternative of components.
The QD (Quick Detachable) design offers both conventional (flange outboard) and invert (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 qd bushing china anti-seize lubricants.
2. Slide QD bushing on shaft, flange end initial. Assemble key.
3. Position QD bushing on shaft. Tighten set screw over key “hand tight” with regular Allen wrench only. Usually 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 to ensure that the two extra holes in the hub can be found as far as possible from the bushing’s noticed cut.
5. Tighten pull-up bolts alternately and evenly to tightness indicated in torque desk on back. Do not use extensions on wrench handles. There should be a gap between your encounter 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 SHOULD NOT BE CLOSED.
Make use of a tapered or QD bushing from Ever-Power with sheaves, pulleys, sprockets and many other power tranny applications. Flanged quick-disconnect bushings feature a completely split style to help provide easy set up and disassembly. A tapered bushing with directly edges uses an interior screw to greatly help drive the bushing into 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 refer to both types as a “taper lock” because they both utilize the tapered wedging action to lock to the shaft. The taper bushing, with it’s straight sides, uses a set screw to operate a vehicle the bushing in to the bore of the component becoming set up (sheave, sprocket, etc.). Be careful when setting up these screws. The holes with threads on the bushing are for removal only. Also remember that the looks of a flange externally of the bushing doesn’t necessarily mean it’s a QD design. Split Taper bushing also has a flange, and both are not 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 holding power. QD Bushings are utilized 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 easily removed utilizing the cap screws as jack-screws. Double drilled holes are furnished in QD Bushings permitting mounting of product in the conventional or reverse positions. This enables cap screws to end up being installed through item hub or bushing flange whichever is definitely most convenient. A substantial benefit in set up, cap screws are at all times inserted from the outside where they are easily accessible. QD Bushings can be found from stock with all well-known 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 pressure is necessary over standard bored-to-size bushings. Quick-Disconnect Bushings are essential for mounting v-belt drives, synchronous belt drives and roller chain drives.
