The disadvantage of these simple teeth is that the velocity ratio is not constant and changes as the teeth go through the meshing cycle causing noise and vibration problems at elevated speeds. The solution to this problem can be achieved by using a profile on the gear teeth, which gives a ...
Future assessments could use a ratio of ALDFG risk-to-seafood production to assess gear-specific relative risks locally and globally, similar to assessments of vulnerable fisheries bycatch by using bycatch-to-target catch ratios49. This would enable the assessment of risk from ALDFG to be balanced...

The Ree-Eyring fluid is assumed to incorporate the non-Newtonian effect, which is represented in the generalized Reynolds equation. Influences of the ratio between the Young's modulus of the coating and the substrate on the contact performance, such as pressure, film thickness, tooth friction ...

and the engine is connected to the planetary carrier while the motor/generator (MG) 1 is connected to the sun gear. The power of the SPGS is transmitted to the output shaft of the AMT by ring gear. The AMT is used to change the speed ratio of the drive motor (MG2) to the output ...
Specifically, the gear is an injection-molded gear made of a polyacetal resin composition comprising more than 5 and less than 100 parts by mass of a filler (II) having a particle size distribution satisfying a particular expression and an average aspect ratio (L/D), i.e., a ratio of ...
This configuration will produce an increase in gear ratio, equal to 1+A/S. These are all described by the equation: (2+n)ωa+nωs−2(1+n)ωc=0, where n is the form factor of the planetary gear, defined by:If the ring is held stationary and the sun gear is used as the ...
A gear system includes gears that each have a tooth flank profile that includes a convex addendum and a concave dedendum, and when in mesh satisfy the Euler Savory equation for conj
