20110271780 | NON-TRANSMISSION-ERROR AND NON-BACKLASH GEARS - As for the gears, this invention makes the transmission angle error and the backlash very small, and reduces vibration and mechanical sound. If form of the teeth in gears are made into the circle, at the angle which the peak of a tooth top and the peak of a tooth bottom overlap, the backlash of the gears will be made to zero. As for the other mesh angle, the correct degree of transmission angle is included in the range of the backlash. If it sets it as 1 cycle to become mesh of the same condition, as for one half of cycles, it will be in the condition which the tooth top and the tooth bottom replaced, and will become the same mesh. If the slice of the gears of the circle-tooth is made as the helical gear by the detailed lamination, the mesh from which the phase shifted exists in that pitch point, and the action of the gears are limited at a zero-backlash-part. Hence, if it is the helical gear of the phase-width of more-1/2-cycles of the circle-tooth, it will be an exact-transmission-angle in all the rotation-angles, and it will become mesh of the zero-backlash. Moreover, it sets up the margin to the collision direction and has the tooth-form-shaping, as the zero-backlash of the aforesaid gears is maintained. | 11-10-2011 |
