Dynamic Behaviour of Spur Gears
Proceedings of the Institution of Mechanical Engineers, 1963In an earlier paper by one of the authors (9) a theoretical analysis suggested that, at certain speeds, large vibrations can occur in a pair of spur gears, without any manufacturing errors and without any external excitation, provided the damping is less than about 0·07 of critical.

Transmission Efficiency of Polymer Spur Gears Meshing with Polymer as Well as Metal Spur Gears
2021Polymer gears are replacing metal gears in various applications nowadays. Polymer gears are deployed in lightweight applications and frequently used in robotic field. Various type of movement takes place in robot. Therefore, transmission efficiency (TE) is a key concerned for robot motion.

Investigation into nitrided spur gears
Journal of Materials Engineering and Performance, 1996The cold forging method has been widely used in industry to produce machine parts. In general, gears are produced by shaping or hobbing. One of the shaping techniques is precision forging, which has several advantages over hobbing. In the present study, cold forging of spur gears from Ti-6A1-4V material is introduced.

The simplest method by which a gear can be cut is to use a tool shaped exactly like the tooth space of the gear. This method of cutting gears is known as form cutting. In practice, the cutting tool is generally a milling cutter, such as the one shown in Figure 5.1. The gear blank is held stationary while the cutter is fed slowly in the direction of the

The Torque Responses in Spur Gearing
Volume 1A: 25th Biennial Mechanisms Conference, 1998Abstract In this study, the frequency spectra of a meshing spur gear pair are derived. A two-step mesh stiffness model is assumed to account for the time varying stiffness during the teeth engagement. The analytic load of this simplified gear pair system is used to derive the corresponding Fourier expansion series of the transmitted ...

Interference Between External Spur Gears
2020In this chapter, the problems of interference between external spur gears in both cutting and working conditions are first described and discussed. The discussion is quite general and therefore includes involute or primary interference and fillet interference.

Load Capacity of the HCR-Spur Gears in Comparison with Standard Spur Gears
1998This paper deals with the load capacity of high contact ratio (HCR) external involute spur gears with theoretically accurate profile in comparison with the standard external involute gears. First, tooth root and Hertzian stress for a HCR- and standard gear pairs are calculated according to DIN 3990 and then compared.
