Abstract
605,104. Toothed gearing. KEELAVITE CO., Ltd., and JOHNSON, E. H. Dec. 14, 1945, No. 33886. Drawings to Specification. [Class 80 (i)] [Also in Group XXVI] In a rotary pump of the gear-wheel type, the compression of liquid in the spaces between adjacent lines of sealing contact of the intermeshing teeth is reduced or prevented by cropping the teeth of the driven gear-wheel, leaving them otherwise of the normal involute form for a gear of the diameter which the gear would have in its uncropped form, while the teeth of the driving gear are uncropped. The extent of the cropping may be such that the sealing flanks of each pair of teeth do not come into engagement until the line of sealing contact of the preceding pair lies a small distance (not greater than that represented by 2 degrees of gear.wheel rotation) in advance of the plane which is common to the axes of the gears. The cropping may be effected by reducing the diameter of the gear-wheel before or after the teeth have been cut or at an intermediate stage or partly by one or more of these methods. There may be more than two gears, and the gears may have different pitch diameters.
