RISMathematical Model of Universal Hypoid Generator With Supplemental Kinematic Flank Correction Motions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A mathematical model of universal hypoid generator is proposed to simulate virtually all primary spiral bevel and hypoid cutting methods. The proposed mathematical model simulates the face-milling, ...
Serration Design for a Gear Plunge Shaving Cutter
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The surface roughness of the work gear after plunge shaving is affected primarily by the arrangement of the serrations. Given the two possible shaving conditions—up cutting and down cutting—this ...
Fourth-Order Kinematic Synthesis for Face-Milling Spiral Bevel Gears With Modified Radial Motion (MRM) Correction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The use of a fourth-order motion curve is proposed by Stadtfeld and Gaiser to reduce the running noise of a bevel gear set recently. However, the methodology of synthesizing the tooth surfaces ...
Flank Modification Methodology for Face-Hobbing Hypoid Gears Based on Ease-Off Topography
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The fundamental design of spiral bevel and hypoid gears is usually based on a local synthesis and a tooth contact analysis of the gear drive. Recently, however, several flank modification ...
Modified-Roll Profile Correction for a Gear Shaping Cutter Made by the Lengthwise-Reciprocating Grinding Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The tooth profile error of a gear shaping cutter made by the lengthwise-reciprocating grinding process (LRGP) is usually corrected by modifying the grinding wheel profile. However, such grinding ...
Tooth Contact Analysis of Longitudinal Cycloidal-Crowned Helical Gears With Circular Arc Teeth
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposes a new type of double-crowned helical gear that can be continuously cut on a modern Cartesian-type hypoid generator with two face-hobbing head cutters and circular-arc cutter ...
Flank Correction for Spiral Bevel and Hypoid Gears on a Six-Axis CNC Hypoid Generator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Because the contact patterns of spiral bevel and hypoid gears are highly sensitive to tooth flank geometry, it is desirable to reduce the flank deviations caused by machine errors and heat ...
Rotor Profile Design for the Twin-Screw Compressor Based on the Normal-Rack Generation Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposes a method for designing the rotor profiles of twin-screw compressors using a rack defined in the normal plane. All tooth profile segments are explicitly defined as tangent ...
Kinematical Optimization of Spiral Bevel Gears
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Kinematical optimization and sensitivity analysis of circular-cut spiral bevel gears are investigated in this paper. Based on the Gleason spiral bevel gear generator and EPG test machine, a ...
The Undercutting of Circular-Cut Spiral Bevel Gears
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Undercutting is a serious problem in designing spiral bevel gears with small numbers of teeth. Conditions of undercutting for spiral bevel gears vary with the manufacturing methods. Based on ...
