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.

In fact, coupling failure is such amon problem that many machinery operators consider it simply part of the process that just has to be dealt In this paper we obtain based on an idea of M. Knott and C. S. Smith (1994, Linear Algebra Appl.199,) characterizations of solutions of three-coupling problems by reduction to the by means of coupling.

SECTION 8 KEYS AND COUPLINGS. 1. FLAT AND SQUARE KEYS DESIGN PROBLEMS 521. A 2-in. shaft, of cold-drawn AISI 1137, has a pulley keyed to it.

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

Design the keyway in the motor shaft extension. Check the shear strength of the key against the normal strength of the shaft. Solution. Given : P = 15 kW = 15 × 103 W N = 960 r.p.m. d = 40

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,

The. hubs of the coupling are each 111mm in diameter, 92 mm thick. and the flange webs are 19 mm thick. Six 16 mm blots in a. 165mm diameter bolt circle connect the flanges. The keyway
