Crank drive for high performance piston pump - involves method of ensuring reliable meshing of gears on two shafts

摘要

The crank drive is for a high performance piston pump. It has an input shaft which can be coupled to a drive and which runs parallel to the crankshaft. Gears on the input shaft mesh with gears on the crankshaft and the gear wheels (4,6) are provided with inclined teeth such that they mesh with a constant angle, and the input shaft (7) is axially displaceably coupled with the drive. USE/ADVANTAGE - Crank drive for piston pump in which the gear wheel seats can be made to the same production tolerances to give a uniform torque transmission.
