Device for the lubrication of tooth flanks of gear wheels

Claim 1

In a device for the lubrication of tooth flanks of two meshing gear wheels that contact each other with one said gear wheel rotating on a shaft having a lubrication flow passageway defined therein to present lubricant to the gear wheel rotating thereon comprising a toothed lubrication applying wheel defining therein radial passages disposed for feeding lubricant from the shaft through the substantially radial passages in the applying wheel by means of inlet openings leading into the radial passages being defined in the wheel and out of outlets opening out in the surfaces of flanks of the teeth of the applying wheel to thereby feed said lubricant from said shaft passageway into successive inlet openings and out respective successive tooth flanks to lubricate the meshing flank surfaces as the wheel is rotated, the improvement comprising in combination, each tooth being provided with at least two separate passages circumferentially spaced about said shaft to successively encounter said passageway feeding lubricant in the shaft with each passage defining only one outlet opening, the respective passages having outlet openings axially spaced and radially offset with respect to each other on the same tooth flank, whereby the inlet openings on the wheel are so arranged relative to the passageway in the shaft that each passage into the wheel, during rotation of the applying wheel, is successively brought into communication with said passageway in the shaft.
