FIELD: process engineering.
SUBSTANCE: proposed device comprises three or more set of guide grooves made on shaft or spindle. To up the precision of centering each said set consists of two grooves. One of said grooves features smaller depth while another one has larger depth. Note here that proposed device is provided with cord made of elastic material. Said cord is fitted in grooves to allow location of the cord in deeper groove in absence of drive contact or minor drive contact with the hub. In the case of cord location in shallow groove tight drive contact with said hub is ensured.
EFFECT: higher precision of centering.
