The initial sheave and pulley installation program developed to facilitate installation and replacement of components.
The QD (Quick Detachable) design offers both conventional (flange outboard) and invert (flange inboard) installation configurations.
1. Be sure the tapered cone areas of the bushing and the within of the driven item are clean and free from anti-seize lubricants.
2. Slide QD bushing on shaft, flange end first. Assemble key.
3. Position QD bushing on shaft. Tighten arranged screw over key “hand 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.
Take note: Install M thru S bushings in the hub so that the two 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 table on back. qd bushing china Usually do not use extensions on wrench handles. There must be a gap between your face of the sheave or sprocket hub and the flange of the QD bushing to insure a satisfactory 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 several other power transmitting applications. Flanged quick-disconnect bushings feature a completely split design to help provide easy set up and disassembly. A tapered bushing with straight edges uses an interior screw to greatly help drive the bushing into the shaft, while a split taper has 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 standard or reverse installation. They are stocked in well-known finished bore sizes and minimum plain bore for customized reboring.
Many people make reference 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, runs on the set screw to drive the bushing in to the bore of the component getting set up (sheave, sprocket, etc.). Be cautious when installing these screws. The holes with threads on the bushing are for removal only. Also remember 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 both aren’t interchangeable. The QD design includes a split that proceeds through the flange. The Metal QD (Quick Disconnect) Type bushing offers flexible and easy installation while providing exceptional keeping power. QD Bushings are used thought out the industry offering convenience and design versatility. They are precision machined of quality Metal and are set up by tightening a number of cap screws. This draws the bushing into 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. 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 item hub or bushing flange whichever is definitely most convenient. A substantial benefit in installation, cap screws are usually inserted from the exterior where they are often accessible. QD Bushings are available from share 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 used on 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.
Our immediate supply chain to Martin Sprockets factories gets a wider selection of QD Bushings delivered at the right time at the proper price.
Taper bushing are widely used together with sprockets, v-belt pulleys, timing pulleys, coupling and other mechanical parts with taper bore connections.
Taper bushing series are constructed with high quality engineered components with great tolerance. The feature is easy to make use of and needs no extra alteration. These bushings can fit almost all sorts of assemblies and sizes. They will be the best choice in style for mechanical connections.
No costly re-boring: complete selection of both metric and imperial available.
Standard range fits up to 125mm/5″ shafts & Hub diameter required depends upon the application.
Complete short reach range obtainable, for compact lightweight assemblies & Clean, Compact Style.
Simple 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) mounting configurations.
1. Be sure the tapered cone surfaces of the bushing and the inside 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 arranged 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.
Notice: Install M thru S bushings in the hub so that the two extra holes in the hub can be found 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. 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 reasonable cone grasp and press fit.
