The gear transmission system was parametric modeled in the software Pro/E to establish the prototype, and imported into ADAMS. The meshing force curves of time domain and frequency domain were reached through dynamic simulation. Then the gear system was optimized with several constraint conditions, such as the number of surface modes, helix angle, cutting Author: Hong Du Zhang, Tao Sun.

This LCM was developed to model spur gear transmissions in presence of defects, in order to prognosticate the dynamic response of these kinds of systems (predictive maintenance) . The estimation of gear stiffness is an important parameter for determining loads between the gear teeth when two sets of teeth are in contact.
In this paper, a 2-D tooth model is developed for finite elements by: 1. Gearbox dynamics are characterized by a periodically changing stiffness due to multiple teeth contacts. In real gear systems, a backlash also exists that can lead to a loss in contact between the teeth.
Due to this loss of contact, the gear has piecewise linear stiffness characteristics. This paper examines the effect of backlash in the two-stage gear by: Experimental investigations concerning the gears efficiency are presented in [3,9,15] for spur gear, helical gear systems and hypoid gear pairs.
Dynamic analysis of. nonlinear oscillations of spur gear pairs with backlash on planetary gear pairs. Huang  set an optimized mathematical model of gear transmission system on the basis of a nonlinear purely rotational dynamic model of a multistage closed-form planetary gear, aiming at minimizing the vibration displacement of the low-speed carrier.

Non-linearity. A three-dimensional design space involving the gear size, diametral pitch, and operating speed was developed to illustrate the optimal design of spur gear pairs. The study performed here indicates that as gears operate over a range of speeds, variations in the dynamic response change the required gear size in a trend that parallels the dynamic Cited by: The two-parallel shaft gear transmission system is the most widely used system among the multi-stage gear transmission systems.

According to the dynamic analysis of gear pair system above, it can be known that the periodic-n and chaotic motion will appeared under the external order to control the dynamic behaviors of the non-smooth system, a time delay feedback is introduced in this by: 1.gear arrangement used in one of his early engines.
However, advances in internal gear manufacturing did not parallel those in external gears, limiting the development of epicy-clic gear trains. As industrial applications required transmissions with higher power ratings, the performance of epicyclic gear systems became poorer at higher loads since.Kinematic Equivalence of Planetary Gear Transmissions Mueller’s book (Ref.
