Proper design of a reciprocating machine requires an estimate of bearing loads - preferably as a function of crank angle. If the friction characteristics of individual bearings are known in terms of load and angular velocity, then drive mechanism efficiency may be estimated to the enhancement of the value of the design study. This paper argues that this exercise is particularly pertinent to the case of the Stirling machine with rhombic drive. Means are outlined for computing bearing loads and estimating overall mechanical efficiency of such machines. To provide an example of the method, General Motors' PD-46 engine is simulated.
