Why do taper keys have a gib?
Some taper keys have a gib , or tab, for easier removal during disassembly, hence the name Gib Head Keys See our Taper Key Dimensional Charts. The purpose of the taper is to secure the key itself, as well as, to firmly engage the shaft to the hub without the need for a set screw.

What are Gib head keys used for?
Gib keys, or gib head keys, are tapered and notched machine keys that are used on power transmission keyed shafts to hold pulleys and gears tightly on the shaft. The head of the key serves as a concussion point for hammering without damage to the shaft of the key.
What is the taper on a gib head key?
These keys have a tapered body that wedges in to the keyway for a more secure fit than standard machine keys. The gib head makes these keys easy to remove when parts need to be taken apart frequently, such as for maintenance or prototyping. Keys are tapered along their length.
How do you remove a gib head key?
They all involve two things: loosening the key (which is probably seized tight) by heat, penetrating oils or solvents, etc.; and removing the key with either a wedge and hammer, a puller of sorts or a percussion/impact/slide hammer to shock it loose. Of course, if all else fails, you can drill it out.
What is a taper key?
Tapered keys The keyway in the hub has a taper that matches that of the tapered key. Some taper keys have a gib, or tab, for easy removal during disassembly. The purpose of the taper is to secure the key itself, as well as, to firmly engage the shaft to the hub without the need for a set screw.
Why is it called a Woodruff key?

What is a feather key?
Definition of feather key in machinery. : a sunk key without taper that is permanently fixed in one of the connected pieces and that is a sliding fit in a keyway in the other so as to permit relative longitudinal motion. — called also spline.
What kind of tool can be used to remove the tapered key?
Drill drift is a wedge-like tool which is used for removing the taper shank tools from the nose of the machine spindle.
What is a saddle key?
: a key for securing a member to a machine shaft that fits into a keyway in the secured member and is concave to grip the shaft by friction compare flat key, sunk key.
Why do we taper keys?
(i)Taper keys : It is tapered (standard taper of this key is 1 in 100) in thickness but uniform in width. A taper key joint prevents relative rotational as well as axial movement between the two pieces.
What is a shaft key?

What is the ratio of key way taper?
They are steel rods with one end having a slightly larger diameter than the other. Standard inch-sized tapered pins have a taper on diameter of 1:48[1] while metric ones have a taper of 1:50.
When the thickness of a key reduces along its length it is called?
A sunk key is a key in which half of the thickness of key fits into the keyway in the shaft and half in the keyway of the hub. The sunk keys are of the following types: Rectangular sunk key: It is the simplest type of key and has a rectangular cross-section. A taper of about 1 in 100 is provided on its top side.
What is sunk key?
Definition of sunk key : a key that fits into keyways in both the shaft and the secured member in machinery — compare saddle key.
