Description

Изобретение относитс к машиностроению , а именно к смазочным устройствам, и предназначено дл автоматической подачи смазки к узлам трении, работающим в закрытых объемах, например к зубчат1,1м парам , подшипникам и др.The invention relates to mechanical engineering, in particular to lubricating devices, and is intended for the automatic supply of lubricant to friction units operating in closed volumes, for example, gear 1,1m pairs, bearings, etc.

Цель изобретени - увеличение времени работы масленки между заправками ее путем увеличени полезного объема под смазку при неизмененных габаритах.The purpose of the invention is to increase the operating time of the oil can between its refills by increasing the useful volume for lubrication with unchanged dimensions.

На чертеже изображена масленка, про- дольный разрез.The drawing shows an oiler, longitudinal section.

Устройство состоит из корпуса 1, выполненного в виде цилиндра с 2 и 3. Внутри корпуса размещены сильфоны 4, герметично закрытые с обеих сторон кольцеобразными крыщками - внутренней 5 и на- ружной 6 с направл ющими по сками и размещенными в них храповыми механизмами 7, контактирующими со щтоком 8., на котором нарезаны кольцевые канавки со скосом. Полость между сильфонами заполнена термическим веществом.The device consists of a case 1, made in the form of a cylinder with 2 and 3. Inside the case there are bellows 4, hermetically closed on both sides by ring-shaped lids - internal 5 and external 6 with guide pins and ratchets 7 placed in them, contacting with a brush 8., on which annular grooves with a bevel are cut. The cavity between the bellows is filled with a thermal substance.

Во фланце имеетс обратный клапан 11, обеспечивающий дозированную подачу смазки.The rod 8 is fixedly connected to the piston 9, which, together with the housing M 1 and the flange 2, forms a cavity 10 filled with lubricant. There is a check valve 11 in the flange that provides a metered flow of lubricant.

При работе узла трени в полость выдел етс тепло, и термическое вещество, расшир сь, удлин ет сильфоны, перемеща крышку со штоком 8 и порщнем 9, выдавливает смазку из полости 10 через обратный клапан 11 в трубопровод, ведущий к узлу трени .

When the friction unit is in operation, heat is released into the cavity, and the thermal substance, expanding, lengthens the bellows, moving the cover with the stem 8 and the piston 9, squeezes grease from the cavity 10 through the check valve 11 into the pipeline leading to the friction unit. The cover 6 at the same time remains fixed. When the operation of the friction unit stops, heat is no longer generated, and then the temperature of the surrounding lubricator decreases.

Claims

The invention relates to mechanical engineering, in particular to lubricating devices, and is intended to automatically supply lubricant to friction assemblies operating in closed volumes, for example, gear pairs, bearings, etc. The purpose of the invention is to increase the operating time of the lubricator between refills by increasing the useful volume for lubrication with unchanged dimensions. The drawing shows the oiler, a longitudinal section. The device consists of a housing 1, made in the form of a cylinder with 2 and 3. Inside the housing there are bellows 4, hermetically closed on both sides by ring-shaped caps - inner 5 and outer 6 with guide pins and ratchets 7 placed in them, contacting with a rod 8., on which annular grooves with a bevel are cut. The cavity between the bellows is filled with a thermal substance. The rod 8 is fixedly connected to the piston 9, which, together with the housing 1 and the flange 2, forms a cavity 10 filled with lubricant. There is a check valve 11 in the flange that provides a metered flow of lubricant. The outer cover 6 is fixedly connected to the flange 3 and the housing 1. The device operates as follows. The oil can is installed in the same flat G – H bone where the friction knot is located. When the friction unit is in operation, heat is released into the cavity, and the thermal substance, expanding, lengthens the bellows, moving the cover with the stem 8 and the piston 9, squeezes grease from the cavity 10 through the check valve 11 into the pipeline leading to the friction unit. The cover 6 at the same time remains fixed. When the operation of the friction unit stops, heat is no longer released, and then the temperature of the surrounding lubrication medium decreases. When the temperature decreases, the substance between the bellows 4, compressed, moves the cover 5 towards the cover 6. The rod 8 and the piston 9 remain stationary, as the ratchet mechanism of the cover 6 abuts against the annular grooves of the rod. The device for applying pressure to the piston returns to its original position, thus ensuring that the lubricator is ready for further work. Filling the oil can is done by filling the cavity I and lubricating and reinstalling with the rod to the extreme position. The invention The lubricator comprises a housing, a cavity with lubricant and a device for creating pressure; An envelope comprising a brush with a brush and a bellows filled with a thermal substance and closed on the inside and outside of the cover with guide pins and with ratchet mechanisms built into each of them that interact with the annular grooves with a bevel with the possibility of piston movement to the side of the cavity with lubricant characterized in that, in order to increase the operating time of the lubricator without recharging by increasing the free volume for lubricant with the same dimensions of the lubricator, the device for creating pressure is equipped with an internal they have an additional bellows forming with the outer bellows and lids a closed cavity for the thermal substance, the lids are ring-shaped, and the slides are located on their inner surface, the outer lid is fixed to the housing, and the piston rod is housed in the guides, and annular grooves with a bevel are made on the outer surface of the stem.
