However for any drive with a given center distance and a speed ratio, only two non-standard asymmetric rack cutters, one for the pinion and other for the gear are used to generate a required numbers of pinion and gear with different cutter shift values for the purpose of optimization.
This paper, using planetary non-circular gear train, synthesizes still another special kind of indexing mechanism, covering three gear trains with different gear types.
Figure 5a shows reference circle method to calculating gear volume with different number of tooth and modification coefficients.
Figure 5b shows average circle method for calculating gear volume with different numbers of tooth and modification coefficients.
The spur gear billet volumes with different gear teeth and various modification coefficients are obtained by using the reference circle method, average circle method and three-dimensional modeling method, respectively.
One aviation official said that the way the plane had veered off the runway suggested several possibilities: that engines were operating at different thrust levels; that brakes on the two main landing gears were operating with different effectiveness; or that thrust reversers on the engine had not deployed symmetrically.
Sampling gear varied between lakes, but not in a systematic way, and detectability of hybrid and parental Phoxinus should not differ with different sampling gear – when Phoxinus species do coexist in a lake, they shoal together and are usually caught together.

30 The BMJ, recognising that different readers have different information needs, now produces several versions of an article, including the pico summary, each geared towards readers with different information requirements.
To test the ability of the dependence-based feature vector in fault classification for a real planetary gearbox, experimental vibration signals with different gear fault levels at different gears are classified by a multi-class support vector machine.
