Description

Изобретение относится к машиностроению, а именно к распиливающим > устройствам с преимущественным использованием для распыления масляного $ тумана при смазке деталей различных машин.The invention relates to mechanical engineering, namely to sawing> devices with a predominant use for spraying oil mist in the lubrication of parts of various machines.

Известна распылительная насадка, преимущественно к генератору масляного тумана, содержащая корпус с .θ входным и сужающимся выходным каналами и размещенную между ними втулку, наружная поверхность которой снабжена винтовой канавкой, сообщающейся с каналами корпуса 11].Known spray nozzle, mainly to an oil mist generator, comprising a housing with .θ inlet and tapering output channels and a sleeve located between them, the outer surface of which is provided with a helical groove in communication with the channels of the housing 11].

Недостатком известной распылитель- 15 ной насадки является то, что процесс коагуляции частиц масляного тумана, происходящий при завихрении потока, недостаточно интенсивный. В результате этого выходящий из узла трения 20 воздух содержит значительное количество частиц масла. Это вызывает загрязнение атмосферы в цехе^ избыточный расход смазочных материалов и ухудшение смазки узла трения.A disadvantage of the known spray nozzle 15 is that the process of coagulation of oil mist particles that occurs when the flow swirls is not intensive enough. As a result, the air leaving the friction assembly 20 contains a significant amount of oil particles. This causes air pollution in the workshop ^ excessive consumption of lubricants and deterioration of the lubrication of the friction unit.

Цель изобретения - интенсификация процесса коагуляции частиц масла.The purpose of the invention is the intensification of the process of coagulation of oil particles.

Указанная цель достигается тем, что во втулке выполнено осевое сквоз- 30 ное отверстие, в котором соосно установлен сердечник, при этом на наружной поверхности сердечника также имеется винтовая канавка с направлением нарезки, противоположным направлению нарезки канавки на втулке.This goal is achieved by the fact that an axial through hole 30 is made in the sleeve, in which the core is coaxially mounted, while on the outer surface of the core there is also a helical groove with the cutting direction opposite to the direction of the groove cutting on the sleeve.

На фиг. 1 представлена предлагаемая распылительная насадка в разрезе; на фиг. 2 - втулка, общий вид·.In FIG. 1 shows the proposed spray nozzle in section; in FIG. 2 - sleeve, general view ·.

Распылительная насадка содержит корпус 1 с входным 2 и сужающимся выходным 3 каналами, между которыми размещена втулка 4 с винтовой канавкой 5 на наружной поверхности. В осевой расточке втулки 4 установлен сердечник 6, на наружной поверхности которого также выполнена винтовая канавка 7 с направлением нарезки противоположным направлению нарезки канавки на втулке. Канавки соединяют входной и выходной каналы корпуса.The spray nozzle comprises a housing 1 with an inlet 2 and a tapering outlet 3 channels, between which a sleeve 4 with a screw groove 5 is placed on the outer surface. In the axial bore of the sleeve 4, a core 6 is installed, on the outer surface of which a helical groove 7 is also made with a cutting direction opposite to the direction of cutting the grooves on the sleeve. Grooves connect the input and output channels of the housing.

Работает распылительная насадка следующим образом.The spray nozzle operates as follows.

Масляный туман от генератора масляного тумана под давлением поступает во входной канал распылительной насадки. Затем поток разделяется и проходит по винтовым канавкам втулки и сердечника. Так как площадь винтовых канавок меньше площади подво3 дящей магистрали, при движении в винтовых канавках скорость масляноготумана увеличивается, увеличивается число столкновений частиц масла межДу собой и со стенками канавок и происходит коагуляция отдельных частиц масла.Oil mist from the oil mist generator under pressure enters the inlet channel of the spray nozzle. Then the flow is divided and passes through the helical grooves of the sleeve and core. Since the area of the helical grooves is less than the area of the supply line, when moving in the helical grooves, the speed of the oil mist increases, the number of collisions of oil particles between themselves and the walls of the grooves increases, and individual oil particles coagulate.

На выходе из винтовых канавок в выходном канале корпуса противоположно направленные потоки масляного тумана сталкиваются. При этом процесс коагуляции частиц масла еще более интенсифицируется. Далее масляный туман с крупными частицами масла по ступает в узел трения, где конденсируется на смазываемых деталях.At the exit of the helical grooves in the outlet channel of the housing, oppositely directed flows of oil mist collide. At the same time, the process of coagulation of oil particles is even more intensified. Further, oil mist with large particles of oil enters the friction unit, where it condenses on lubricated parts.

Такая конструкция распылительной насадки позволяет значительно интенсифицировать процесс коагуляции частиц масла при распылении масляного тумана и улучшить условия смазки де- 20 талей.This design of the spray nozzle makes it possible to significantly intensify the process of coagulation of oil particles during the spraying of oil mist and to improve the lubrication conditions of parts.

Claims

The invention relates to mechanical engineering, namely to atomizing devices with a predominant use for spraying oil mist when lubricating parts of various machines. A known spray nozzle, mainly to an oil mist generator, comprising a housing with inlet and tapered outlet channels and an sleeve disposed between them, is provided with a helical groove, combined with the channels of housing 11. A disadvantage of the known spray nozzle is that the coagulation process oil mist particles occurring during flow turbulence are not intense enough. As a result, the air leaving the friction unit contains a significant amount of oil particles. This causes pollution of the atmosphere in the workshop, excessive consumption of lubricants and deterioration of lubrication of the friction unit. The purpose of the invention is to intensify the process of coagulation of oil particles. This goal is achieved by that an axial squib bore is made in the sleeve, in which the core is coaxially mounted, while on the outer surface of the core there is also a screw groove with a cutting direction opposite to the cutting direction of the groove on the sleeve. FIG. 1 shows the proposed spray nozzle in a section; in fig. 2 - sleeve, general view-. The spray nozzle includes a housing 1 with an inlet 2 and tapering output 3 channels between which sleeve 4 with a helical groove 5 is placed on the outer surface. In the axial bore of sleeve 4 a core 6 is installed, the screw groove 7 with the cutting direction opposite to the outer surface of the sleeve 4 cutting grooves on the sleeve. The grooves connect the inlet and outlet channels of the housing. Powered sprayer. Nozzle as follows. The oil mist from the oil mist generator under pressure enters the inlet of the spray nozzle. The flow is then separated and passes through the helical grooves of the sleeve and core. Since the area of the helical grooves is smaller than the area of the supply line, when moving in the screw grooves, the speed of oil mist increases, the number of collisions of oil particles between themselves and with the walls of the grooves increases and coagulation of individual oil particles occurs. At the outlet of the helical grooves in the body outlet channel, oppositely directed oil mist flows collide. In this process, the coagulation of epie oil particles is more intensified. Then the oil mist with large particles of oil enters the friction unit, where it condenses on lubricated parts. This design of the spray nozzle allows to significantly intensify the process of coagulation of oil particles during the spraying of oil mist and to improve the lubrication condition of oil. The invention of the spray nozzle, mainly to the oil mist generator, comprises a housing with inlet and suction outlet channels and a sleeve disposed between them, the outer surface of which is provided with a helical groove communicating with the channels of the housing, characterized in that, in order to intensify the coagulation process oil particles, in the sleeve there is an axial through hole, in which the core is coaxially mounted, while on the outer surface of the core there is also a screw groove with the direction ki, opposite to the direction of cutting of the groove on the sleeve.
