摘要： A replaceable flight liner for screw flights in screws of the type adapted for pumping fluid-like material (especially thick, fibrous suspensions) through a casing. The liner is suitable for use on screws subject to short life because of screw flight wear on outside surfaces. It is expected that a plurality of such liners would be worn out before other, more extensive repairs to a pump would be necessary.

摘要： A rotor structure is disclosed for a fluid compressor of the character having a pair of complementary, intermeshing rotatable rotors for transferring and compressing a fluid from an inlet into the compressor to an outlet from the compressor. The rotor includes helical land and intervening helical groove means for intermeshing with complementary helical land and groove means of a complementary rotor. The helical land and groove means includes a first portion having a first constant helix angle and a second portion having a second constant helix angle which is different from the first helix angle. The two helical portions are disposed on shaft means and meet in a transition area intermediate the opposite ends of the shaft means and in which area the lands and grooves are disposed in mating relationship. One of the helical portions is integral with the shaft means, and the other helical portion is defined by a separate component adapted to be mounted on the shaft means and suitably interconnected with the one helical portion.

摘要： A screw rotor machine and rotors therefore wherein the machine includes a casing defining a working space having a pair of parallel intersecting bores with a fluid inlet port and a fluid outlet port. A pair of cooperating rotors are mounted within the working space with each having helical lands and grooves with a wrap angle of less than 360*. The rotors are positioned to cooperate with each other and with the sidewalls of the working space to define chambers for working fluid which move from the fluid inlet to the fluid outlet and decrease in volume as the rotors are rotated to thereby compress fluid confined in the chambers. One of the rotors is of the female type and includes helical lands and intervening grooves which lie substantially completely inside the pitch circle of the rotor. The other rotor is of the male type and includes helical lands and intervening grooves which lie substantially completely outside the pitch circle of the male rotor. In a plane transverse to the longitudinal axes of the rotors, the grooves in the female rotor and the lands on the male rotor are a novel assymetrical design. One flank of the groove in the female rotor and one flank of the land on the male rotor are generated. The other flank of the groove in the female rotor is defined by a circular arc. The major portion of the other flank of the land on the male rotor is defined by a circular arc and a minor portion is line generated. Thus, the leading flank of the male rotor land is substantially circular and the trailing flank is generated.

摘要： This rotor has helical teeth of concave profile extending principally inside of its cylindrical pitch surface. Said profile is tangent to the root surface of the teeth. The pitch point (0, FIG. 2) radially in line with the point (33) of tangency has a larger distance (0-37) from the outer end of the profile than (033) from the root circle, on one side of the teeth. The increase is at least 10 percent of the distance (0-33) from the root circle. Said profile is preferably a circular arc in sections normal to the teeth.
