Numerical and Experimental Study of the Loaded Transmission Error of a Worm Gear With a Plastic Wheel

Journal of Mechanical Design, Transactions of the ASME, 2008
Nowadays, the wheels of worm gears with a low module can be made of plastic; thus, classical modeling can no longer be used satisfactorily. The present paper describes an original method for studying the quasistatic loaded behavior of a worm gear, with a steel worm and a nylon wheel.

Dynamic analysis of high speed gears by using loaded static transmission error

Journal of Sound and Vibration, 1988
Abstract A single degree of freedom non-linear model is used for the dynamic analysis of a gear pair. Two methods are suggested and a computer program is developed for calculating the dynamic mesh and tooth forces, dynamic factors based on stresses, and dynamic transmission error from measured or calculated loaded static transmission errors.

Transmission Error Calculation Based on Manufacturing Errors and Load

Advanced Materials Research, 2014
A valid mathematic model is introduced to study the calculation of gear meshing transmission error, which is based on the manufacturing error and gear teeth deformation. Subsequently, take a pair of specific gear for example;The transmission error curves are obtained by the calculation model.

Planet position errors in planetary transmission: Effect on load sharing and transmission error

Frontiers of Mechanical Engineering, 2013
In this paper an advanced model of spur gear transmissions developed by the authors is used to study the influence of carrier planet pin hole position errors on the behaviour of the transmission. The model, initially conceived for external gear modeling, has been extended with internal meshing features, and thus increasing its capabilities to include ...

An Ease-Off Based Optimization of the Loaded Transmission Error of Hypoid Gears

Journal of Mechanical Design, 2009
Loaded transmission error (LTE) is one of the primary sources of gear noise and vibration. While ease-off topography has been shown to be powerful in improving the contact properties of a gear drive, its optimization to minimize LTEs has been an open problem in the gear literature.

Numerical and Experimental Study of the Loaded Transmission Error of a Spiral Bevel Gear

Volume 5b: Power Transmission and Gearing Conference, 2005
The design of spiral bevel gears in aeronautical gear boxes requires very precise and realistic numerical simulations. One important criteria is the loaded transmission error (LTE) that gear designers attempt to reduce at the nominal torque. This paper presents a numerical tool that simulates the loaded meshing of spiral bevel gears and experimental ...

Analysis of Load Dependent Dynamic Transmission Error Response of Gears With Random Pitch Error

Volume 6C: 18th Biennial Conference on Mechanical Vibration and Noise, 2001
Abstract For more realistic gear dynamic behaviour predictions, detailed gear dynamic models are needed, allowing taking into consideration the most important influencing factors. System model is presented, based on the separate handling of individual tooth pairs, with their specific profile corrections, manufacturing errors etc. Further
