FIELD: transport engineering.
SUBSTANCE: invention relates to the technology of transport engineering and can be used as a method for manufacturing auger spirals of a screw propeller for wheelchairs in order to overcome the last flights of stairs for general use. A method for manufacturing auger spirals, which includes making a springy helical comb on a cylindrical rotor, consists in the fact that a multi-threaded springy helical comb with a multiplicity of two, four or more is performed by twisting a multi-core cable of a trihedral cross section around the longitudinal axis of a hollow cylindrical rotor with fixing the beginning and end of twisting at the ends of the rotor.
EFFECT: simplification and unification of the technology for the production of screw propellers, which can be used as a chassis for wheelchairs in order to overcome the last flights of stairs for general use.
