Design and Investigation of an Asymmetric Logarithmic Spiral Gear Drive

open access: yesApplied Bionics and Biomechanics, Volume 2022, Issue 1, 2022., 2022
Sliding on gear teeth working surfaces has negative effects on the performances of gears, such as tooth surface wear, pitting, etc. In order to reduce the gear sliding during high speed and heavy load, a new type of pure rolling gear, named as an asymmetric logarithmic spiral gear, is designed referring to the characteristics of the Issus planthopper ...

The Computational Fundamentals of Spatial Cycloidal Gearing [PDF]

open access: yes, 2009
The tooth flanks of bevel gears with involute teeth are still cut using approximations such as Tredgold’s and octoid curves, while the geometry of the exact spherical involute is well known. The modeling of the tooth flanks of gears with skew axes, however, still represents a challenge to geometers.

Analysis of Flow Characteristics of Straight Conjugate Crescent Gear Pump at Variable Working Conditions

open access: yesMathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022
The working conditions (i.e., gas content, working pressure, and working temperature) of oil in the actual hydraulic system are always in a dynamic process, which will cause the basic properties of oil (i.e., density, absolute viscosity, and effective bulk modulus) to change and further generate changes of the flow characteristics in the straight ...

Research on adaptive cruise control algorithm considering road conditions

open access: yesIET Intelligent Transport Systems, Volume 15, Issue 12, Page 1478-1493, December 2021., 2021
Abstract As one of the most important ADAS systems, traditional adaptive cruise control is only suitable for relatively simple working conditions such as expressways, and it is difficult to deal with complex traffic environment and road working conditions.

Reduction of gear pair transmission error with tooth profile modification [PDF]

open access: yes, 2008
The gear noise problem that widely occurs in power transmission systems is typically characterised by one or more high amplitude acoustic signals. The noise originates from the vibration of the gear pair system caused by transmission error excitation ...
