qd bushing

Our immediate 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 together with sprockets, v-belt pulleys, timing pulleys, coupling and other mechanical parts with taper bore connections.
Taper bushing series are made of high quality engineered components with great tolerance. The feature is definitely easy to make use of and needs no extra alteration. These bushings can fit almost all types of assemblies and sizes. They will be the best choice in design for mechanical connections.
No costly re-boring: full range of both metric and imperial offered.

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 reverse (flange inboard) mounting configurations.
1. Be certain the tapered cone surfaces of the bushing and the inside of the driven product are clean and free of anti-seize lubricants.
2. Slide QD bushing on shaft, flange end first. Assemble key.
3. Position QD bushing on shaft. Tighten established screw over key “hands tight” with standard 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 both extra holes in the hub are located as far as feasible from the bushing's saw 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 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 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 tranny applications. Flanged quick-disconnect bushings include a completely split style to greatly help provide easy installation 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 an integral on the bushing to greatly help provide more drive.
QD bushings (” and metric sizes) have a flanged design and feature a 4° taper with standard or reverse mounting. They are stocked in popular finished bore sizes and minimum plain bore for customized reboring.
Many people refer 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 being set up (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 appearance 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 are not interchangeable. The QD style has a split that continues through the flange. The Metal QD (Quick Disconnect) Type bushing offers versatile and easy installation while providing exceptional keeping power. QD Bushings are utilized considered the industry offering convenience and design flexibility. They are precision machined of quality Metal and are installed by tightening a number of 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 traditional or invert positions. This allows cap screws to become installed through product hub or bushing flange whichever is certainly most convenient. A substantial benefit in installation, cap screws are often inserted from the outside where they are often accessible. QD Bushings are available from share with all well-known bores within the range of each size bushing.
QD Bushings feature a split tapered flange with the split central to the flange and taper. They are applied to sprockets, sheaves, and pulleys where more clamping power 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.
