Abstract:
A gear assembly of a scavenge oil pump for a vehicle is provided. The assembly comprises a first pair of meshing gears comprising a first drive gear disposed about a drive shaft and a first slave gear disposed about a slave drive in parallel relationship with the drive shaft. The first drive gear and first slave gear are in rotational meshing cooperation. The assembly comprises a second pair of meshing gears comprising a second drive gear disposed about the drive shaft and a second slave gear disposed about the slave drive. The second drive gear and second slave gear are in rotational meshing cooperation. The second pair of meshing gears is disposed linearly adjacent to the first pair of meshing gears. The first pair and the second pair of meshing gears have about ⅜ of a tooth spacing relative to each other for torque transmission of scavenge oil.
