Gear Drive - an overview | ScienceDirect Topics
1979年10月17日 · Gears and Gear Drives. R Keith Mobley, in Plant Engineer's Handbook, 2001. 57.5 Gear drives and speed reducers. Gear drives are packaged units used for a wide range of power-transmission applications. They are used to transmit power to a driven piece of machinery and to change or modify the power that is transmitted.
Face gear drives: Nominal contact stress calculation for flank load ...
2024年5月1日 · Face gear drives are not very well-known special angular gear units. With them, high transmission ratios are possible in small construction spaces. In a face gear drive, a pinion with an involute flank profile meshes with a face gear wheel. As for bevel gear pairings, spur and helical face gear drives are possible with or without center offset.
Geometric design and analysis of face-gear drive with involute …
2019年4月1日 · Meanwhile, fundamental studies on face-gear drives and endurance tests were also conducted at Sikorsky Aircraft to develop face-gear transmissions, also under the RDS-21 program [6]. More recently, the Boeing Company's development of tapered helical face gear technology was structured in response to the Enhanced Rotorcraft Drive System (ERDS ...
Design, generation, and stress analysis of two versions of …
2002年10月1日 · Finite element analysis has been performed for the two versions of face-gear drives represented in Table 1, Table 2. For the second version of face-gear drive, it has been also considered the application of a rounded top shaper (Fig. 5), in order to compare the bending stresses at the fillet of the generated face-gear.
Tribodynamic analysis of spur gear drives with uncertain time …
2024年1月1日 · The requirements of low vibration and high reliability eagerly call for a better dynamic performance of gear drives. Extensive studies have been conducted to investigate the dynamic behaviors of gear drives [1], [2], [3], in which the assumption of constant loads was always made. However, the external loads applied on gear drives are inherently ...
Computerized design, generation and simulation of meshing and …
2000年9月15日 · New types of face worm-gear drives are considered. The authors propose methods for localization of bearing contact and reduction of transmission errors achieved by double-crowning of the worm of the drive with respect to the hob, the tool that generates the worm-gear. A computer program for simulation of meshing and contact is provided.
Reduction of noise of loaded and unloaded misaligned gear drives
2006年8月15日 · The output data of numerical Examples 2 and 3 (represented in Section 5) provide the information about the function of transmission errors of loaded gear drives, formation of bearing contact, and the stress analysis. The purpose of this section is to complement Examples 2 and 3 with comparison of the noise of the considered gear drives.
Integrated computer program for simulation of meshing and …
2000年1月7日 · The program is applicable for various gear drives but needs derivation of tooth surface equations specified for the considered gear drive. The computer program represents a set of integrated operations such as the development of required algorithms, storing in database, copying, deleting, printing, design correction from the database, etc.
A genetic approach to automate preliminary design of gear drives
2009年10月1日 · The research on design of gear drives has mainly focused on dimensional design on single stage gear drives. Researchers have developed several applications using different design and calculation methods (Deb et al., 2000, Su and Wakelam, 1998). A gearbox producing the required output speed was designed by using GA (Pham & Yang, 1993). The ...
A finite element method for 3D static and dynamic contact/impact ...
2007年2月1日 · Gear drives transmit motion and power by tooth mesh. Mostly in the form of involute profiles, gear tooth mesh is a complex process involving, e.g. multi-tooth engagement, multi-point contact and varying load conditions.
