    INTERVIEW SHORT QUESTION ANSWERS-GEARS

    INTERVIEW SHORT QUESTION ANSWERS-GEARS Discuss the advantages and disadvantages of an involutes profile. A. Advantages of involutes profile Manufacturing is accurate and easy. Pressure angle is constant Velocity ratio remains the same by the change of center distance.  Disadvantages of involutes profile Followings are the disadvantages. (i) Interference (ii)  Vibrations (iii)  Noise (iv)  Heat generation (v) Life reduction […]

    Belt-chain -Gear drives 

    Belt-chain -Gear drives   Advantages of V-Belt over Flat Belt Friction is more due to groove (wedge). Thus these transmit more power. Reduced angle of contact and hence more power is transmitted There is no slip in a V-belt since belt runs in a groove.  Compact since distance between two shaft axes is less. Silent drive. […]

    Involute and Cycloid Gear Profiles

      involute and Cycloid Gear Profiles (a) INVOLUTE PROFILE Curve which satisfies the law of gearing is called involute profile. STANDARD INVOLUTE PROFILES (i) 14 ½ involute, addendum length =a = 1/pd , Clearance = C = 0.157/pd , Np min =18 (ii) 200 involute, addendum length = a = 1/pd , Clearance =C = 0.2/pd ,     Np min =18 […]
