Abstract
Изобретение относитс к двигателестроению, в частности к системам смазки топливных насосов, установленных на двигател х. Цель изобретени - повышение эффективности системы. Профильтрованное масло от масл ной магистрали 1 по наклонному каналу 2 в корпусе насоса и через лыску 4 толкател 3 (при положении толкател в НМТ) поступает в верхнюю полость насоса, а затем по каналам 5,6 корпуса насоса через опоры кулачкового вала и радиальный канал 7 между последним и крышкой подшипника сливаетс в картер 8 шестерен двигател . При таком выполнении системы смазки размеры лыски 4 по глубине и высоте позвол ют оптимизировать количество смазки, поступающей в полости насоса, а выход лыски на верхний торец толкател обеспечивает поступление масла преимущественно на верхние детали, наиболее удаленные от ванны насоса, и затем последовательное проникновение его во все полости насоса. 2 ил.FIELD OF THE INVENTION The invention relates to engine-building, in particular, to lubrication systems for fuel pumps installed on engines. The purpose of the invention is to increase the efficiency of the system. The filtered oil from the oil line 1 through the inclined channel 2 in the pump housing and through the tongue 4 pusher 3 (at the position of the pusher at NMT) enters the upper cavity of the pump, and then through channels 5.6 of the pump housing through the camshaft supports and the radial channel 7 between the latter and the bearing cap is discharged into the crankcase 8 of the engine gears. With this implementation of the lubrication system, the dimensions of the flats 4 in depth and height allow to optimize the amount of lubricant entering the pump cavities, and the exit of the flats to the upper end of the pusher provides oil flow mainly to the upper parts furthest from the pump bath, and then successive penetration all cavities of the pump. 2 Il.
Description
; Изобретение относитс к двигателе- (троению, в частности к системам смаз- йи топливных насосов, установленных на двигател х.; The invention relates to engine (construction, in particular, to lubrication systems for fuel pumps installed on engines.
: Цель изобретени - повышение эффективности системы путем оптимизации коли- Цества масла, поступающего в верхнюю ijacTb насоса и наиболее удаленным от масл ной ванны детал м.A: The purpose of the invention is to increase the efficiency of the system by optimizing the amount of oil entering the upper ijacTb pump and parts farthest from the oil bath.
На фиг. 1 представлена предлагаема система смазки; на фиг. 2 - сечение А-А на фиг. 1.FIG. 1 shows the proposed lubrication system; in fig. 2 is a section A-A in FIG. one.
Система смазки содержит масл ную магистраль 1, наклонный канал 2 в корпусе Насоса, один конец которого подключен к Магистрали 1, а другой оканчиваетс во Е|нутренней полости корпуса насоса, в кото- р|ой размещен толкатель 3, на направл ю- фей поверхности которого со стороны ка- Иала 2 выполнена глуха сегментна лыс- На 4, выход ща на верхний торец толка- т;ел . Выход канала 2 в полости насоса р|асположен на уровне конца лыски 4 тол- к|ател 3 при положении последнего в ниж- фй мертвой точке (НМТ).The lubrication system contains an oil line 1, an inclined channel 2 in the pump housing, one end of which is connected to Line 1, and the other ends in the E-cavity of the pump housing, in which the push rod 3 is located, on the surface direction from the side of Ka-Yala 2, the segment bald bald-on-4 is made, coming out to the upper end of the pushes; The output of channel 2 in the cavity of the pump p | is located at the level of the end of the flathead 4, thickness of the body 3, when the latter is located at the bottom dead center (BDC).
i Кроме того, в перемычках корпуса насо- с|а выполнены каналы 5, 6 дл сообще- н|« его внутренних полостей. Полости насоса р адиальным каналом 7 между кулачковым валом И крышкой подшипника сооб- ujeHbi с картером 8 шестерен двигател . Глубина лыски 4 равна половине диаметрального зазора Б сопр жении толкатель - корпус насоса, а ее длина 0,7-0,9 обi In addition, channels 5, 6 have been made in the bridges of the casing of the co-pump and are communicated with its internal cavities. The cavities of the pump are by the radial channel 7 between the camshaft And the bearing cap of the joint ujeHbi with the crankcase of 8 gear wheels of the engine. The depth of the flathead 4 is equal to half of the diametral clearance B of the junction of the pusher - the pump casing, and its length is 0.7-0.9
