Abstract

Inventia se refera la un motor pneumatic rotativ, folosit, în special, pentru actionarea unor dispozitive de rectificat miniaturizate, utilizate în industria mecanicii fine. Motorul pneumatic rotativ se compune dintr-o carcasa în care se afla un rotor solidar cu un arbore sprijinit pe niste rulmenti radiali axiali, tensionati de un arc, fixarea fiind asigurata cu o piulita, alimentarea cu aer comprimat fiind realizata printr-un orificiu practicat într-un capac care se sprijina pe un corp care are la interior un ajutaj convergent, în interiorul ajutajului convergent fiind executate niste canale elicoidale, în continuarea corpului fiind montat un stator în care sunt realizate niste ajutaje convergent-divergent, rotorul avînd niste orificii pentru evacuarea aerului dintr-o camera facîndu-se printr-un canal de legatura, ungerea rulmentilor radiali-axiali, fiind asigurata prin ceata de ulei introdusa printr-un canal de legatura, etansarea fiind asigurata printr-un labirint.The invention relates to a pneumatic rotary motor, used in particular for the operation of miniaturized grinding devices used in the fine mechanics industry. The rotary pneumatic engine consists of a housing in which there is a solid rotor with a shaft supported on axial radial bearings, tensioned by a spring, the fixing being provided with a nut, the compressed air supply being made through a hole in a cap resting on a body having a convergent nozzle inside, inside the converging nozzle being made some helical channels, a stator being mounted in the further part of the body in which convergent-divergent nozzles are made, the rotor having some outlets for the evacuation the air from a chamber being made through a connecting channel, the lubrication of the radial-axial bearings being provided by the oil mist introduced through a connecting channel, the sealing being provided by a labyrinth.
