About this eTextbook

Caused by downsizing of combustion engines, the torque fluctuation at the crankshaft induces torsional vibrations in the powertrain. Manual transmissions and dual clutch transmissions are particularly sensitive to gear-rattle noise. Gear-rattle noise arises from oscillations of loose parts with clearance, e.g. idler gears, synchronizer rings and gearshift sleeves.

The aim of this research is the formulation of a gear oil for the application in a manual transmission to minimize gear rattling noise. Acoustic measurements on a gear-rattle noise test bench verify the noise reduction of the developed gear oils with commonly used low oil viscosity. An analysis of the transmission error proves that gear tooth impacts during rattling lead to elastic deformation of the meshing gear pairs.

The main source for the intensity of gear-rattle noise is the additional presence of meshing impacts at the beginning of each gear pair meshing. Gear-rattle noise reduction can be achieved by avoiding meshingimpacts, e.g. by minimizing the traction coefficient of the gear oil.

Refunds

A digital file cannot be posted back, so there is no return process. There are situations that are refundable and situations that are not, and both are stated plainly.

Refunded in full, within 30 days of the order:

The file is corrupt, truncated, or will not open in a reader that supports its format.
Content is missing from the edition you were sold.
The wrong title was delivered.
The edition, eText ISBN, author or format does not match this page.
You were charged twice for the same title.
Nothing was delivered and we cannot reissue it.

Not refundable: a title you downloaded and then decided you did not want, a file that does not suit your device where we did not say it would, buying the wrong edition when this page stated it correctly, and publisher printing or copy limits.

Approved refunds are issued within 2 to 5 business days to the card that paid. Full detail on the Returns & Refund Policy.
