6.4 Strength of a Sunk Key 6.5 Effect of Keyways 6.6 Couplings 6.7 Summary 6.8 Key Words 6.9 Answers to SAQs 6.1 INTRODUCTION A key is a piece of steel inserted between the shaft and hub or boss of the pulley to connect these together in order to prevent relative motion between them. It is always inserted parallel to the axis of the shaft.

The material for the muff is cast iron for which the allowable shear stress may be assumed as 15 MPa. Solution. 1. Design for shaft. Let d = Diameter of the 

Safe stress for cast iron coupling = 10 MPa Safe stress for key material = 46 MPa Solution. Given : d = 35 mm n = 6. D1

01/07/  · When it comes to vibration, the devil’s in the details. While it’s pretty easy to pinpoint misalignment, propeller issues or a bent shaft, less conspicuous components like shaft couplings, keys and keyways can also cause issues. In mechanical engineering, keys connect rotating elements, in this discussion, couplings to shafts. The key sits in a keyway,

Keys and Coupling 489 Since the service factor is 1, therefore the maximum torque transmitted by the shaft, Tmax = 1 × 159 = 215 N-m = 215 × 10 3 N-mm We know that the torque transmitted by the shaft ( T ), 215 × 10 3 = 16 s dd 331640 ππ×τ × = × × = 7 d 3 ∴ d 3 = 215 × 10 3 / 7 = 27 × 10 3 or d = 30 say 35 mm Ans.

The paper describes a model based approach to provide an integrated structural coupling filter for a military aircraft. It utilises a steady-state version of the well-known Kalman filter, designed using a model containing rigid and flexible modes relevant to longitudinal dynamics, and provides an important alternative to the existing approach

Each part of the process reveals information about the problem and possible solutions. Engineering design is iterative. Engineers are expected to repeat the process. Steps like defining, planning, modeling, and testing, can be completed in different sequences to find the best possible solution. Engineering design is problem-solving.

Sunk Keys. The sunk keys are provided half in the keyway of the shaft and half in the keyway of the hub or boss of the pulley. Rectangular sunk key : The usual proportions of this key are width of key (W) = d/4 and thickness of key (t) = d = diameter of the shaft, The key has taper 1 in 100 on the top side only.

One of the likely key issues with a gear type coupling at 13000 RPM will be sludge collecting in the teeth which can in time partially or totally lock up the coupling; see the attached diagram showing lubricant path through the teeth. This causes forces to be generated that can result in vibration.
