qd bushing

The original sheave and pulley mounting system developed to facilitate installation and alternative 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 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 1st. Assemble key.
3. Position QD bushing on shaft. Tighten established screw over key “hand tight” with standard Allen wrench only. Usually do not use excessive force.
4. Slide large end of sheave or sprocket taper bore into placement 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 can be found as far as feasible 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 must be a gap between the face 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.
Make use of 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 style to 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 greatly help provide more drive.
QD bushings (” and metric sizes) possess a flanged style and show a 4° taper with regular or reverse installation. They are stocked in well-known finished bore sizes and minimal plain bore for custom 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 operate a vehicle the bushing into the bore of the component getting installed (sheave, sprocket, etc.). Be careful when setting up these screws. The holes with threads on the bushing are for removal just. Also be aware that the looks of a flange externally of the bushing doesn’t necessarily mean it’s a QD style. Split Taper bushing also offers a flange, and both aren’t interchangeable. The QD style includes a split that continues through the flange. The Metal QD (Quick Disconnect) Type bushing offers versatile and easy set up while providing exceptional keeping power. QD Bushings are utilized considered the industry offering convenience and design versatility. They are precision machined of quality Metal and are set up by tightening several cap screws. This draws the bushing into 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. Dual drilled holes are furnished in QD Bushings permitting mounting of product in the traditional 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 set up, cap screws are usually inserted from the exterior where they are often accessible. QD Bushings are available from share with all well-known bores within the range of every size bushing.
QD Bushings feature a split tapered flange with the split central to the flange and taper. They are used on sprockets, sheaves, and pulleys where more clamping force 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.

Our direct supply chain to Martin Sprockets factories gets a wider range of QD Bushings delivered at the right time at the proper price.
Taper bushing are widely used as well as sprockets, v-belt pulleys, timing pulleys, coupling and other mechanical parts with taper bore connections.
Taper bushing series are made from high quality engineered materials with great tolerance. The feature can be easy to use and needs no additional alteration. These bushings can fit almost all kinds of assemblies and sizes. They will be the best choice in design for mechanical connections.
No costly re-boring: full selection of both metric and imperial obtainable.
Standard range fits up to 125mm/5″ shafts & Hub diameter required depends upon the application.
Complete brief reach range offered, for compact light-weight assemblies & Clean, Compact Design.
Ease of installation and removal.
The original 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) installation 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 1st. Assemble key.
3. Placement QD bushing on shaft. Tighten set screw over key “hands tight” with regular Allen wrench only. Do not use excessive force.
4. Slide large end of sheave or sprocket taper bore into placement 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 both 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 table on back. Do not make use of 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 hold and press fit.
