contact ratio

contact ratio

[′kän‚takt ‚rā·shō]
(design engineering)
The ratio of the length of the path of contact of two gears to the base pitch, equal to approximately the average number of pairs of teeth in contact. Also known as contact gear ratio.

Gear Mechanics Background: Backlash, Contact Ratio, and Tooth Cut
To go over from the parameter h to contact ratio, the following expression should be used:
They eliminate axial thrust, prevent tilting moments and ensure silent running owing to the larger contact ratio of meshing teeth, improved distribution of heat in the tooth area.

The contact ratio is defined as the ratio between the spreading contact area of liquid over solid surface and the surface area of the spherical drop before spreading.
Internally, the TE15 transmission incorporates high contact ratio spur gears in conjunction with helical gearing, all of which contribute to operating noise levels approximately 10% below its predecessor.
They have the capacity to more cost-effectively deploy the number of highly trained specialists required and the call center technology to achieve a higher right-party contact ratio.
In addition the small cutter has a smaller contact ratio with the part, reducing the tendency for chatter.
