RISSome Limitations in Applying Classical EHD Film Thickness Formulas to a High-Speed Bearing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Elastohydrodynamic film thickness was measured for a 20-mm ball bearing using the capacitance technique. The bearing was thrust loaded to 90, 448, and 778 N (20, 100, and 175 lb). The ...
Surface Geometry of Circular Cut Spiral Bevel Gears
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An analysis of the surface geometry of spiral bevel gears formed by a circular cutter is presented. The emphasis is upon determining the tooth surface principal radii of curvature of crown ...
Special Cases of Friction and Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Two techniques for reducing friction forces are presented. The techniques are applied to the generalized problem of reducing the friction between kinematic pairs which connect a movable link to ...
Synthesis of Solid Elastic Horns
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Synthesis of the profile of a solid elastic horn from its matrix of transfer functions is examined. Two methods of synthesis are developed. The first method makes use of the Inverse Sturm-Liouville ...
Ideal Spiral Bevel Gears—A New Approach to Surface Geometry
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper discusses the fundamental geometrical characteristics of spiral bevel gear tooth surfaces. The parametric representation of an ideal spiral bevel tooth is developed. The development is ...
A Method of Selecting Grid Size to Account for Hertz Deformation in Finite Element Analysis of Spur Gears
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A method of selecting grid size for the finite element analysis of gear tooth deflection is presented. The method is based on a finite element study of two cylinders in line contact, where ...
Constrained Fatigue Life Optimization of a Nasvytis Multiroller Traction Drive
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A contact fatigue life analysis method for multiroller traction drives is presented. The method is based on the Lundberg-Palmgren analysis method for rolling element bearing life prediction, and ...
Simplified Fatigue Life Analysis for Traction Drive Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A simplified fatigue life analysis for traction drive contacts of arbitrary geometry is presented. The analysis is based on the Lundberg-Palmgren theory used for rolling-element bearings. The ...
Dynamic Capacity and Surface Fatigue Life for Spur and Helical Gears
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A mathematical model for surface fatigue life of gear, pinion, or entire meshing gear train is given. The theory is based on the statistical approach used by Lundberg and Palmgren for ...
Experimental and Analytical Load-Life Relation for AISI 9310 Steel Spur Gears
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Life tests were conducted at three different loads with three groups of 8.9 cm (3.5 in.) pitch diameter spur gears made of vacuum arc remelted (VAR) AISI 9310 steel. Life was found to vary ...
