2.1.1.7. Principle of operation of the balancing block

Fig. 2.12. Principle of operation of the balancing block: 1 – adjusting laying; 2 – crankshaft; 3 – forward part of the engine; 4 – case of the balancing block; 5 – counterbalances; 6 – balancing shaft No. 2; 7 – leading gear wheel; 8 – a balancing shaft No. 1 with the conducted gear wheel


Structurally balancing block is installed under a bent shaft, has two balancing shaft and the case bed in which they are located. By means of balancing shaft and adjusting laying adjustment of a gap in gearing with a bent shaft is carried out. Balancing shaft (No. 1 and No. 2) are put in action by the leading gear wheel of a bent shaft. Rotary motion is transferred from the leading gear wheel which is located between radical necks of the third and fourth cylinders, directly to a balancing shaft No. 1 with the conducted gear wheel. The balancing block transfers rotation to a balancing shaft No. 2. The transfer relation of gear wheels of balancing shaft was chosen so that the gear wheel rotated twice quicker than a bent shaft. Speed of rotation of a balancing shaft counterbalances force of inertia of rotation (secondary inertial force of rotation) of a bent shaft. The balancing block does not understand and is not under repair (fig. 2.12).

Fig. 2.13. Marking of adjusting laying of the balancing block: 1 – block of cylinders; 2 – identification tag (2 categories)



NOTE
For adjustment of a gap between the balancing block and the crankshaft replace adjusting laying. There are 40 types of laying of various thickness. To define a type of laying, find marking (2 figures) on laying (fig. 2.13).
