2.1.1.12. Rod and shatunny bearing

Fig. 2.18. Rod and shatunny bearing: 1–expansion; 2–rod; 3–socket surface; 4–rod cover; 5–rod bearing


The rod is made of the structured tempered alloy for rigidity improvement. The usual adjusting shponka of the shatunny bearing is not used. At installation of the bearing measure position of the bearing and establish it so that it was located on the center of a rod and a cover of the shatunny bearing. The bottom head and a rod cover when manufacturing are created as a uniform element, and then divided into a rod and a cover. For combination of a rod and a cover use a configuration of a surface of the socket. The Shatunny bolt has the inhaling moment in a plasticity zone, the inhaling is carried out in two steps. The top loose leaf of the shatunny bearing is made of an aluminum alloy (fig. 2.18).

NOTE
There are three types of loose leaves of shatunny bearings depending on a demanded gap.


Fig. 2.19. Contour of a belt of a drive of auxiliary units: 1–pulley of the pump of the hydraulic booster; 2–driving belt; 3–tension pulley; 4–generator pulley; 5–automatic natyazhitel; 6–pulley of a cranked shaft; 7–pulley of the compressor of central air of air; 8–a pulley of the pump of cooling liquid


In system of a drive of auxiliary units one poliklinovy driving belt is used. It reduces length of the engine and facilitates contour service. For a tension of a belt the automatic natyazhitel with a cylindrical spring is used. The pulley of a natyazhitel automatically supports a tension of a driving belt (2.19).
