Description
Кроме того, при такой конструкции возможно максимально увеличить длину вкладь:шей , т. е. сделать ее всего лишь на -2 мм короче длины накладки. Этим самым увеличиваетс величина опорной поверхности системы «накладка - вкладыил, а следовательно и долговечность.In addition, with such a design, it is possible to maximize the length of the insert: neck, i.e., make it only -2 mm shorter than the length of the lining. In this way, the size of the support surface of the pad-to-insert system, and hence the durability, increases.
Существенно улучшаетс ремонтоспособиость вала как путем перешлнфовки без отрицательных влений, цроисход щих при уменьшении диаметров шеек и радиусов галтелей (накладки ие демонтируютс ), так п со сменой накладок. Это позволит не уменьша ремонтного размера производить вкладыши одного типоразмера.The shaft is repaired significantly as by transferring without negative effects, which occur when the diameters of the necks and radii of the fillets are reduced (the linings are not dismantled), as well as by changing the linings. This will allow not reducing the repair size to produce liners of the same size.
При этом срок службы коленчатого вала ие лнм1ггируетс износом и определ етс лишь его усталостной прочностью. Износостойкость сопр жени шейки - накладки - вкладыши в предлагаемой конструкции выше, чем в ri.iвестных . Это обеспечено улучшенным маслоснабжением подшипника, так как осуществл етс гарантированна подача масла через отверсти 6, 7 и пазы 5 и .9 и более равномерное заполнение маслом зазора между вкладышами и накладками в результате упеличепп количества точек дл выхода r-.iac.i; (те же отверсти ) и в результате лучшего распределени маела в продольном сечеинп по канавке 10.At the same time, the service life of the crankshaft and lnm1 is aggravated by wear and is determined only by its fatigue strength. The durability of the neck-lining mate-liners in the proposed design is higher than in the well-known ri. This is ensured by improved bearing oil supply, since oil is guaranteed to flow through holes 6, 7 and grooves 5 and .9, and the oil fills the gap between liners and linings more evenly as a result of increasing the number of points for r-.iac.i output; (the same holes) and as a result of a better distribution of mel in the longitudinal section along the groove 10.
Наличие зазоров между буртами шеек и торцами пакладок (илп се между щеками и торцами накладок в случае, когда толщина накладок больше высоты буртоз) позвол е: обрабатывать наружные цилиндрические поверхности иакладок с выходом инструмента, что предопредел ет получение более высокой точности продольного сечени .The presence of gaps between the collar of the necks and the ends of the packings (or between the cheeks and the ends of the linings in the case when the thickness of the linings is more than the height of the burtosis) allows you to work on the outer cylindrical surfaces of the folds with the tool output, which determines a higher accuracy of the longitudinal section.
