Machine Theory Dynamic tooth loads of planetary gear sets having tooth profile wear
A computational model of a planetary gear set is employed to study the influence of surface wear on the dynamic behavior of a typical planetary gear set. The overall computational scheme combines a wear model that defines geometric description of contacting gear tooth surfaces having wear and a deformable-body dynamic model of a planetary gear set. The wear model employs a quasi-static gear con...
متن کاملResearch on Tooth Modification of Spur Bevel Gear
Isometric modification is proposed as a new method of axial modification of spur bevel gear. Based on the gear geometry theory and the normal meshing motion equation of gear pairs, changes of meshing points and angles are analyzed and the effect of axial modification on meshing movement of gear pairs is discussed. After that, a method of drawing spherical involute with the aid of SolidWorks sof...
متن کاملFinite Element Analysis and Tooth Profile Modification Study on Traction Gear of High Speed and Heavy Load Locomotive
Base on the characteristics of high-speed and heavy-load locomotive traction gear, a pre-grinding hob was designed which increased the thickness of the dangerous tooth root section as much as possible. The deformation and stress of the traction gears were calculated through the parameterized model established by finite element method. The tooth profile modification was implemented considering t...
متن کاملDynamic Meshing Characteristics of Elliptic Cylinder Gear Based on Tooth Contact Analysis
As the most important working area of gear, teeth play the role of transmitting load and power. Tooth line and tooth profile are the two main characteristics of the tooth surface, which affect the shape of the tooth surface, tooth meshing characteristics and contact characteristics. Taking the elliptical cylinder gear pair in the reversing device of a new type of drum pumping unit as the resear...
متن کاملInvestigating Vibration Properties of a Planetary Gear Set with a Cracked Tooth in a Planet Gear
Comparing with fixed shaft gearbox, vibration properties of planetary gearbox are much more complicated. In a planetary gearbox, there are multiple vibration sources as several pairs of sun-planet gears and several pairs of ringplanet gears mesh simultaneously. In addition, the signal transmission path changes due to the rotation of the carrier. To facilitate fault detection of a planetary gear...
