Ball-Bearing Motor
The discovery/invention of the ball-bearing motor is attributed to Milroy [1]. It has been discussed several times, with conflicting explanations [2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15]. This solution is a much simplified version of that given in [7]. Because the motor is weak, it is helpful to reduce friction on the axle by connecting the high-current lead to the outer races of the ba...
متن کاملB Ball Bearing ▶ Bearing Bar Extrusion
Introduction Bar extrusion is a process in which a block of metal (billet) is forced to flow by compression through a tool (die) opening of a smaller crosssectional area than that of the original billet. There are two basic types of bar extrusion: direct and indirect. The most important and common method used is the direct extrusion (Lange 1988). Figure 1 shows the principle of direct bar extru...
متن کاملFast in Situ X-ray Diffraction Analysis during Quenching of a Ball Bearing Steel
This paper presents the results of time and temperature resolved analysis of changes in phase composition and stresses/residual stresses during quenching and martensitic transformation of steel. Sample temperatures up to 900°C were reached with a specially-designed furnace, in which fast cooling of sample is executed by gas quenching. Stress development during quenching followed the expected tr...
متن کاملVibrational Analysis of a Ball Bearing
The project presents an analysis of the vibrational behavior of a deep groove ball bearing with a structurally integrated force sensor. The miniaturized force sensor, accommodated within a slot on the bearings outer ring, provides online condition monitoring capability to the bearing. Analytical and finite element models are developed to predict the sensor output due to bearing dynamic load and...
متن کاملExperimental Investigation on Radial Ball Bearing Parameters Using Taguchi Method
In this work, characteristics of various ball bearing parameters are studied under different loads and rotational speeds. By using Dimensional Analysis (DA), dimensionless parameters are computed which provides solution for a group of parameters. This analysis can be accomplished by using the Buckingham π-theorem. DA leads to reduction of the number of independent parameters involved in a probl...
