# Key Sizes For Shafts

Key Sizes For Shafts. Design the rectangular key for a shaft of 50 mm diameter. The average medium dart shaft is about 50 millimetres.

Shaft keys are divided into the main 5 categories. Parallel keys are most commonly used.

Parallel keys are most commonly used. Metric keyways are dimensioned by width and depth as measured from the radius of the shaft to the center of the keyway.

The key and key seat cross section are iso standardized. The shearing and crushing stresses for the key material are 42 mp and 70 mpa.

See dimensions w and h in figure 1. Square keys preferred for shaft diameters above this line:

#### Over Width. W Height. H

Parallel keys are most commonly used. The key and key seat cross section are iso standardized. The key length should be less than about 1.5 times the shaft diameter to ensure a good load distribution over the entire key length when the shaft becomes twisted when loaded in torsion.

#### Parallel Keys. Keyways. Deep Pattern.

Metric keyways are dimensioned by width and depth as measured from the radius of the shaft to the center of the keyway. = 70 mpa = 70 n/mm. Referencing figure 1. the metric key size is w x t.

#### In Order To Find Out The Length Of The Key To Transmit The Full Power Of The Shaft. The Shearing Strength Of The Key Should Be Equal To The Torsional Shear Strength Of The Shaft.

Design the rectangular key for a shaft of 50 mm diameter. Parallel keys are most commonly used. In the metric system it is common practice to specify the key size.

#### The Key Length Should Be Less Than About 1.5 Times The Shaft Diameter To Ensure A Good Load Distribution Over The Entire Key Length When The Shaft Becomes Twisted When Loaded In Torsion.

Keyway and corresponding key sizes for english shafts are listed below in table 1. It is usually used for shafts less than about 60 mm diameter and the keyway is cut in the shaft using a milling cutter.
