Description

Przedmiotem wynalazku jest swider do wiercen obrotowych posiadajacy ulozyskowane gryzy, zwlaszcza malych srednic.The subject of the invention is a rotating drill bit with located cutters, in particular small diameters.

Znane swidry do wiercen obrotowych posiadaja cylindryczne lozyska slizgowe, lozyska kulowe i lozyska oporowe.Known rotary drill bits have cylindrical plain bearings, ball bearings and bearings thrust.

Stan techniki znany jest z polskiego opisu patentowego nr. 74031.The state of the art is known from the Polish patent description no. 74031.

Swider wedlug wynalazku wyposazony jest w slizgowe lozysko stozkowe przenoszace obciazenia dzialajace na lozysko promieniowe i czesciowo poosiowe. Na biezni lozyska stozkowego posiada komory wypelnione smarem stalym, który zwilza powierzchnie stozkowe lozyska swidra.According to the invention, the swider is equipped with a load-bearing conical plain bearing acting on radial and semi-axial bearing. It has chambers on the tread of a tapered bearing filled with grease which wets the tapered surfaces of the auger bearing.

Przez zastosowanie wynalazku uzyskano przedluzenie trwalosci lozyska oraz usunieto przypadki utracania sie czopka lozyskowego.By applying the invention, the service life of the bearing was extended and the loss cases were eliminated a suppository.

Przedmiot wynalazku jest przedstawiony w przykladzie wykonania na rysuku, na którym fig. 1 przedstawia przekrój wzdluzny ulozyskowania gryza swidra, a fig. 2 - przekrój poprzeczny przez komory smarowe lozyska stozkowego. Ulozyskowanie gryza 1 sklada sie z cylindrycznego lozyska promieniowego 2, kulowego lozyska promieniowego 3 i lozyska stozkowego 4. Czop lozyska stozkowego 4 posiada komory 5 wypelnione smarem, który rozprowadzany jest na powierzchnie lozyska stozkowego 4.The subject of the invention is presented in an example of embodiment in the drawing in which Fig. 1 shows longitudinal section of the drill bit bearing, and Fig. 2 - cross section through the lubricating chambers conical. The bearing of the cutter 1 consists of a cylindrical radial bearing 2, a ball bearing radial 3 and tapered bearing 4. The journal of the tapered bearing 4 has chambers 5 filled with grease, which is distributed on the surface of the tapered bearing 4.
