. Design of Hydraulic Bearing Puller and Pusher:

1)      Design Consideration:

- Load capacity of Hydraulic Jack (W) = 5 ton (50 KN)

 - Operating Pressure (p) = 80 Kgf

 - Lift Range (L) = 20 cm

 -Man effort put on handle (e) = 20Kg

 - Permissible tensile stress of mild steel (6t) = 120 N/mm2

- No. of stroke for lifting load (n) = 150

- Factor of safety = 5

- Permissible shear stress of mild steel (τ) = 20 N/mm2

 - Permissible comp. stress of mild steel (6c) = 20 N/mm2

- Permissible comp. stress of cast iron (6c) = 120 N/mm2

 - Permissible shear stress of cast iron (τ) = 35 N/mm2

2)      Design of Hydraulic Jack: The material of hydraulic jack is cast iron and having capacity of 5 ton i.e.50 KN. Material used for handle and jack plate is mild steel.

- Outer diameter of jack (Do) = 60 mm

 - Inner diameter of jack (Di) = 30 mm

- Oil capacity in reservoir at bottom of jack = 200 ml

 - Handle attached to jack (l*b*t) = ( 280 mm*10 mm*8 mm)

- Plate attached to jack (l*b*t) = ( 150 mm*100 mm*10 mm)

 - Central hole on plate for jack = 60 mm

- Vertical stud rod attach to both sides diagonally to the jack plate(l) = 310 mm

- Stud rod through both sides of plate of diameter = 6 mm

3)      Design of Bearing Clamp: Bearing clamp made up of mild steel and having sitting arrangement to bearing when pushing of bearing into shaft. The sitting arrangement is of in elliptical shape.

- Bearing clamp dimension (l*b*t) = ( 180 mm*90 mm*14 mm)

- Inner elliptical size on shaft = 80 mm

 

 - Outer elliptical size on shaft = 110 mm
