This program is applicable in the following ranges: dimensionless velocity parameterU being from 10-12 to 10-10 , dimensionless load parameter W from 10-5 to 10-3, and the rate of slide to roll S less than 0.1, which, except for S, can involve the practical applications of industry gear drives.
Such a way helps solve the problem of formulating a complicated model for optimizing the design,and combine the optimal design with CAD of gear drives,making the optimization of the design more practicable.
Based on the optimal design and the norm of reliability design and applying mathematical statistical theory and fuzzy principle, the author has established the mathematical model of optimal design of cylindrical gear drives in fuzzy reliability, chozen optimal methods and given optimization parameter.
In order to resolve the packing and layout problem for multi-stage gear drives at the conceptual design stage,the three-dimensional layout model of gear drives has been established,and the universal constraint equations of the location of drive elements,geometry and strength have been derived.
The sled (occupied by a cadaver) is accelerated by a eightfold gear transmission ratio through a drop weight until it reaches a desired crash velocity (max.
In the design stage of a gear drive with spur or helical gears, there is need for a reliable simulation of the vibrations, mainly because of their sound generation.
According to enhanced interest for use of micro mechanical gear drives increased requirements occur for the transmittable power output with at same time proceeding miniaturization.
The procedure was proven to be safe and reliable in rating the load capacity and useful in the design of worm gear drives with compact size and high power transmission.
Results show that there can be four situations for meshing boundary line on the tooth surface of gear, namely, inexistence of meshing boundary line, a unique line, two lines, and two coincident lines.
Compared to the famous TRALLFA spherical gear, this new spherical gear has an involute tooth profile, and a ring tooth that is distributed continuously on the surface of the sphere.
