What is the taper on a taper lock bushing?
A taper-lock bushing gets its name from the 8 degree taper from one side to the next before it locks into place. This reduces the necessary length-thru-bore for any application. An internal screw holds the taper-lock bushing in place, providing a slimmer fit than a flanged bushing.
What do the numbers on a taper lock mean?
The Taper-Lock bushing size is defiined by 4 digits representing two numbers. The first two digits represent the maximum bore size and the second two digits represent the bushing length. For example, product number 1008 has a max bore of 1.0″ and a total length of 0.8″
How do you measure a taper lock bushing?
If there is no number on the bush or it is damaged. In this instance we need to measure the inside diameter of the bush and the outside diameter of the bush at the largest point. Our example was 24mm shaft size and 38mm at the largest diameter.
What angle is a taper lock bush?
8 degrees
The Taper-Lock® design has a taper angle of 8 degrees or 1-11/16” taper per foot, which minimizes end disk deflection. However, of all hub and bushing systems, it has the lowest ability to grip the shaft.
How do you measure a taper lock bush?
What does QD bushing mean?
Quick Detachable
QD® Bushing. QD® The original sheave and pulley mounting system 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.
Do taper locks need a key?
The Taper Lock bush, also referred to as a Taper bush or Taper Fit bush, is a locking mechanism commonly used in Power Transmission Drives for locating pulleys, sprockets, and couplings to shafts. The Taper Lock bush is pre-bored and keyed to match the required shaft and keyway diameters.
What is taper lock pulley?
Taper lock bush pulley allows unskilled labor to achieve coupling of pulleys and shrink fit on shafts using just hexagon wrench. It has arrangement of longitudinal split tapered bushes and half-threaded holes that give easy, fast fitting and maximum grip.
What is a taper lock hub?
Taper Lock Hubs and Adaptors are standardized components that are used to fasten components to shafts using conical Taper bushes. The hubs or adaptors are firmly connected to the component. Once fixed, the component is capable of transmitting torque while being secured against axial displacement.
What angle is a taper lock?
The Taper-Lock® design has a taper angle of 8 degrees or 1-11/16” taper per foot, which minimizes end disk deflection. However, of all hub and bushing systems, it has the lowest ability to grip the shaft.
