Mafotokozedwe a unyolo wozungulira mizere iwiri

Mafotokozedwe a maunyolo ozungulira okhala ndi mizere iwiri amaphatikizapo chitsanzo cha unyolo, chiwerengero cha maulalo, chiwerengero cha ma rollers, ndi zina zotero.

1. Chitsanzo cha unyolo: Chitsanzo cha unyolo wozungulira mizere iwiri nthawi zambiri chimakhala ndi manambala ndi zilembo, monga 40-2, 50-2, ndi zina zotero. Pakati pawo, nambalayo imayimira wheelbase ya unyolo, gawo lake ndi 1/8 inchi; chilembocho chimayimira kapangidwe ka unyolo, monga A, B, C, ndi zina zotero. Mitundu yosiyanasiyana ya unyolo ndi yoyenera zida zosiyanasiyana zamakina ndipo iyenera kusankhidwa malinga ndi momwe zinthu zilili.
2. Chiwerengero cha maulalo: Chiwerengero cha maulalo a unyolo wozungulira wa mizere iwiri nthawi zambiri chimakhala nambala yofanana. Mwachitsanzo, chiwerengero cha maulalo a unyolo wa 40-2 ndi 80. Chiwerengero cha maulalo chimakhudza mwachindunji kutalika ndi mphamvu yonyamula katundu ya unyolo, ndipo chiyenera kusankhidwa malinga ndi zosowa zenizeni.
3. Chiwerengero cha ma rollers: M'lifupi mwa unyolo wa roller wa mizere iwiri nthawi zambiri amakhala 1/2 inchi kapena 5/8 inchi. M'lifupi mwa maulalo osiyanasiyana ndi oyenera zida zosiyanasiyana zamakina. Kukula kwa m'lifupi mwa unyolo kudzakhudzanso mphamvu yonyamula katundu ya unyolo. Mphamvu ndi nthawi yogwirira ntchito.
