He aha te Cam Bearing? Ngā āhuatanga me te tiaki o te Cam bearing

 

He momo peara anō hoki te peara cam, he matotoru te mowhiti o waho o te peara roera ngira me te hanganga whakakotahi o te pūtu; he hongere hinu whakahinuhinu te pūtu o te peara; he porotaka, he porowhita te mata o waho o te mowhiti o waho, ka taea te whiriwhiri kia rite ki te tono tūturu; he momo eccentric te momo e whakamahia ana mō ngā camshafts motuka (ngā pou e whakahaere ana i te whakatuwheratanga me te katinga o ngā takirere i roto i ngā miihini piston) nā te mea he watea ki te whakatika tika i te tūranga tuaka o ngā pūtu i te wā e whakairihia ana ngā peara.

 

Ngā āhuatanga o ngā peera cam:

 

1. He hanganga matotoru o te mowhiti waho o te roera ngira me te huinga pūtu;

 

2. He raupapa ine me te raupapa imepera te rahi;

 

3. Kei roto i te pūtu o te peera he awa hinu whakahinuhinu;

 

4. Hei whakahaere i te tāutanga, kua hoahoatia te pito nui o te peera me te aratau huihuinga kī "kupu kotahi" me te "momo kōhao hexagonal";

 

5. He porotaka, he porowhita hoki te mata o waho o te mowhiti o waho, ka taea te whiriwhiri kia rite ki te tono tūturu;

 

6. He pai te momo roera katoa mō ngā wā e pikau ana i ngā kawenga nui me ngā tere iti;

 

7. Ka taea e te momo rerekē te whakarite ngāwari me te tika i te tūranga o te tuaka o te pūtu i te wā e tāuta ana i te peera.

 

Te tiaki i ngā peera cam:

 

1. Ko te papu hurihuri hou kua whakamahia me whakakapi ki te hinu i muri i te 100 hāora o te mahi, kātahi ka whakakapia i ia 500 hāora o te mahi.

 

2. I muri i te 1500 hāora o te mahi, me whakakapi te hinu, kaua hoki te nui o te hinu e nui rawa, e iti rawa rānei, nā te mea ka wera te peera mēnā ka nui rawa, ka iti rawa rānei te hinu, ā, me whakahaere te nui o te hinu i te nuinga o te wā.

2/1----2/3 o te rōrahi o te rūma kawe.

 

3. Mō ngā peera kua pania ki te hinu whakahinuhinu, me tāpiri te nui o te hinu ki te tūranga kua tohua.

 

4. Me horoi, me hiri hoki te ipu kei roto te hinu whakahinuhinu, te hinu rānei i ngā wā noa, ā, kaua hoki e waiho he puehu, he paru rino me ētahi atu mea, kia kore ai e kino te peera.

 

5. He mea hanga te peera o te motuka ki te hinu nano, he ātete ki te pāmahana teitei (125 °C), engari he ngāwari ki te wairewa i roto i te wai, nō reira kāore e taea te whakamahi mō te whakahinuhinu i ngā peera papu wai.
