FIELD: machine building.
SUBSTANCE: screw engine stator comprises hollow housing accommodating stator sleeve with internal screw multi-start teeth and coating with internal screw multi-start teeth made from elastomer, for example, from rubber, secured in said stator sleeve. Stator sleeve is secured on inner cylindrical surface of stator hollow housing by thermostable glue composition. Note here that maximum clearance between housing and sleeve surfaces makes not over 0.4-0.5 mm per diameter.
EFFECT: longer life and higher reliability, increased axial load.
