A double-screw compressor for supplying gas, such as air, to a gas consumer, is provided. The double-screw compressor includes two interacting rotors for compressing the gas and a toothed gearing. The toothed gearing includes a gearing housing with two opposite end walls made of a first material. Two gearwheels made of a second material which has a thermal expansion coefficient different from the thermal expansion coefficient of the first material are mounted in the end walls. In order to reduce the effect of the temperature on the backlash, both gearwheels are designed with one and the same pressure angle which is smaller than 15°.read more

David L. Wakefield,Weishun Ni +1 more
TL;DR: A gear root is defined by a stretched root blended into an involute tooth profile curve within a True Involute Form diameter as mentioned in this paper, and a gear root can be defined by any root root.

Low-excitation gearing
TL;DR: In this paper, a substantially constant mesh stiffness is achieved by shaping the teeth and the field of contact, so that the product of incremental tooth contact line length and tooth pair stiffness per unit length of contact line integrated over the field-of-contact does not vary significantly.

Screw rotor profile and method for generating
TL;DR: A screw rotor profile for both male and female rotors is generated from a single rack in which each individual rack segment includes four discrete circular arc segments and two discrete straight line segments.
Patent
Screw compressor with involute profiled teeth
TL;DR: A screw-type gas compressor has a pair of meshing rotors each formed with a plurality of helical ribs as mentioned in this paper, and the flanks of the ribs of one of these rotors are generally convex and at least partially formed as involutes.

Rotary oil pump
TL;DR: In this article, a tapered land continuously in circumferential direction of the end of flat washer sliding against the end face of drive gear was provided to reduce abrasion at the gear thrust receiving section.
