Dimension the holes and shafts for the required linear toler

Solution

For type of fit R3: Hole is H7 and Shaft is f6

The Standard tolerance limits are

For hole H7- 0 to 1.2( in)

For shaft f6- -1.2 to -1.9( in)

The hole tolerance= upper limit -lower limit=1.2-0=1.2 in=0.0012 in

The shaft tolerance= upper limit -lower limit=-1.2-(-1.9)=0.7 in=0.0007 in

Max. hole size=Basic size+upper limit=2+0.0012=2.0012 in

Min. shaft size=Basic size+lower limit=2-0.0019=1.9981

Maximum Clearance= Max. hole size- Min. shaft size=2.0012-1.9981=0.0031 in

Min. hole size=Basic size+ lower limit=2+0=2 in

Max. shaft size=Basic size+ upper limit=2-0.0012=1.9988

Minimum clearance=Min. hole size- Max.shaft size=2-1.9988=0.0012in

Allowance =Maximum clearance- Minimum clearance=0.0031-0.0012=0.0019in

The hole tolerance= upper limit -lower limit=1.2-0=1.2 in=0.0012 in
