卡特彼勒CAT柴油發(fā)動(dòng)機(jī)活塞、活塞環(huán)和連桿修理技術(shù)

Caterpillar CAT diesel engine piston, piston and connecting rod

卡特彼勒CAT柴油發(fā)動(dòng)機(jī)鋁活塞有一鐵圈作為頂上兩環(huán)，這有助于減少壓縮環(huán)槽上的磨損，一個(gè)空腔鑄進(jìn)恰好在頂環(huán)槽后的活塞里。來自活冷卻噴射器的滑油流經(jīng)這空腔，冷卻活塞，改善活塞環(huán)的壽命，活塞具有三道環(huán)，二道壓力環(huán)和一道油環(huán)。所有的環(huán)都裝在活塞銷孔以上，油環(huán)為標(biāo)準(zhǔn)(傳統(tǒng))式，滑油通過油環(huán)槽孔回軸軸箱，頂上兩道環(huán)是梯形式，錐形，活塞環(huán)槽也是錐形，槽中環(huán)的作用有助于防止環(huán)因太大的碳粒而被卡住。

Aluminum piston ring as a top two ring, which helps to reduce the wear on the compression ring groove, a hollow cast into just at the top of the piston ring groove in the. The cooling jet oil is flowing through the cavity, piston cooling, improve the life of the piston ring, the piston has three ring, two pressure ring and an oil ring. All rings are arranged on the piston pin hole, oil ring for standard (conventional) type, the oil through the oil ring slots back axle box, the top two ring is the ladder form, conical, piston ring groove groove is tapered, the central role of helps prevent ring was stuck due to too much carbon particles while.

卡特彼勒CAT柴油發(fā)動(dòng)機(jī)連桿銷孔端有一錐度，這使連桿和活塞在最大載荷區(qū)城具有更大的強(qiáng)度。處于一小角度的四個(gè)螺栓連接連桿大端，這種設(shè)計(jì)使連桿寬度最小，因而可獲得較大的連桿軸承，而且連桿可以通過缸套卸出。

Connecting rod pin hole with a taper, which makes the connecting rod and the piston has greater strength in the maximum load zone. In the four bolts connecting rod big end and a small angle, this design of the connecting rod of minimum width, thereby obtaining a connecting rod bearing large, and connecting rod through the cylinder unloading.
