Litlhoko tsa tlhahlobo ea boleng ba likere kamora ho tima lisebelisoa tse tima tsa maqhubu a phahameng

1. Boleng ba bokaholimo

Meno ha a lokela ho chesoa haholo, ebe o hlahloba hore na ho na le mapetso a meno, tlhahlobo ea 100% bakeng sa lihlopha tse nyane, le tlhahlobo ea lihlopha tse kholo ho latela karolelano e boletsoeng.

2. Bokaholimo ba thatafalo

100% tlhahlobo bakeng sa lihlopha tse nyane, tlhahlobo ea lihlopha tse kholo ho latela karolelano e boletsoeng, ka kakaretso e hlokang thatafalo ea 45-50HRC, le mojaro o phahameng oa 50-56HRC.

3. Mokhatlo o hlophisitsoeng

Tobetsa ZBJ36 009-88 ho hlahloba.

4. Botebo bo thata ba lera le thatafetseng

U sebelisa Vickers thatafala mohlahlobi, karolong ea sefapano sa leino bohareng ba leino bophara: lekanya ho tloha holimo ho ea hare, bofelo ba ho thatafala ha lera le thata ke bo latelang: moralo.

5. Kabo e thata ea lera

1) Bakeng sa likere tse nang le m <4mm, ho thatafatsa meno ka botlalo hoa lumelloa, mme tlase ea leino e na le lera le itseng le thata, ka kakaretso 1.2mm.

2) Bakeng sa likere tse nang le m = 4.5-6mm, ha u sebelisa ho futhumatsa le ho tima ka nako e le ‘ngoe, bophahamo ba leino la 1/3 ho tloha motso oa leino ho lumelloa hore bo ka ts’oaroa,’ me ha leino le le leng le ntse le tima, bophahamo ba leino la 1/4 le lumelloa ho ba sa mameloe.

3) Bakeng sa likere tse tima ka nako e ts’oanang, botebo ba setsi se thatafalitsoeng sa karolo ea longitudinal ea gear e feta 2/3 ea botebo ba lera le thatafetseng.

4) Ha lisebelisoa tsa ka hare m <6mm, lera le thatafalitsoeng le lumelloa ho ba le letsoapo le lenyane.

5) Bakeng sa ho qhekella ho thatafalitse likere tse kholo tse nang le m> 8mm, bophahamo ba leino le thatafalitsoeng bo lokela ho ba makhetlo a 1.7 ka modulus, mme ha m <8mm, 2/3 bophahamo ba leino bo lokela ho thatafala.

Sengoloa sena se hlahisa hakhutšoanyane lintho tsa tlhahlobo, litaba le litlhokahalo tsa likere tse tima tsa lisebelisoa tse tima tsa maqhubu a phahameng. Ke ts’epa hore e tla thusa mosebetsing oa hau.
