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

ii) the shaft diameter on the basis of torsional rigidity. Compare the results of these two examples and comment on the results. Solution. Given G = 79 300 N/ 

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.

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

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.

03/10/  · Here are six common mistakes made in assembly and maintenance of flexible couplings. Misalignment— While couplings are designed to allow some misalignment and varying degrees of flex, excessive misalignment between joined shafts is one of the most common reasons for failure. Often, a mechanic will not check the alignment before installing a

Muff coupling is also called sleeve coupling or box coupling. It is a type of rigid coupling. It consists of a sleeve or a hollow cylinder, which is fitted over the ends of the input and output of the shaft by means of a sunk key. It is the simplest form of coupling with only two parts sleeve and key. It is simple to design and manufacture.

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.
