Abstract
The utility model relates to a lubricating device for a machine. A bearing on a mechanical motion component is usually lubricated by filling oil into an oil hole or an oil cup which is arranged on a bearing seat. The utility model is provided with a main oil tank and an auxiliary oil tank. An oil pump is arranged on the main oil tank; an oil inlet pipe of the oil pump is communicated with a bearing seat, and an oil outlet pipe of the oil pump is communicated with the main oil tank. One end of an oil conveying pipe which extends from the main oil tank is provided with a filter, the other end of the oil conveying pipe is communicated with the bearing seat, thereby, a closed lubrication system is formed. Compared with the traditional mode, the utility model has the advantages that a bearing does not need to be filled with oil regularly, dirty oil does not need to be cleaned, and the service life of the bearing is extended.
Description
The utility model relates to a kind of mechanical lubrication device, is mainly used in various types of bearing lubrication.
Lubricating of bearing on the various mechanical moving elements before the utility model generally is that tank filler sleeve or lubricating cup are set on its bearing support.The mechanical wear and the heating that produce when preventing mechanical relative movement need to adopt the new lubricant oil of the oil gun injection of the oilhole on bearing support constantly, or add new lubricant oil to lubricating cup termly.Even now, but because the sump oil that contains wearer that remains in the bearing can not in time be removed, fresh lubricating oil and remaining sump oil are in case mixing still exists the problem of aggravating bearing wear.
In view of the above problems, the purpose of this utility model provides a kind ofly neither need take artificial intermittent oiling, does not need regular dismounting bearing to remove the negative pressure closed-circuit lubrication device of sump oil again.
The task that the utility model proposed is realized by following measure:
It is provided with two fuel tanks in this device, one is main fuel tank, and another is a drop tank, and drop tank is provided with an oil pump, and the oil inlet pipe of oil pump communicates with each bearing support.Oil outlet tube communicates with main fuel tank; Be provided with a transport pipe in main fuel tank, the one end is provided with a filter cleaner, and the other end communicates with each bearing support, thereby forms the lubrication system of a sealing.
When oil pump pump oil, the oil suction from bearing constantly of the oil inlet pipe of oil pump, make bearing form negative pressure, and the transport pipe that communicates with bearing support is constantly replenished from the cleaning lubricant oil that main fuel tank sucks through the filter cleaner filtering to bearing, thereby reached lubricated purpose.
Compared with the prior art the utility model not only need not adopt artificial mode, termly bearing is refueled, or unpicks and washes bearing, removes sump oil, and has prolonged the working life of bearing widely.
An embodiment of the present utility model has been described in the accompanying drawing
Fig. 1 is a negative pressure closed-circuit lubrication schematic representation of apparatus
For the ease of understanding the utility model, existing embodiment in reference to the accompanying drawings is described in detail:
The structural representation of negative pressure closed-circuit lubrication device has been described among the figure, it has a main fuel tank 1, with a drop tank 8, main fuel tank is provided with pressure gauge 5, oil temperature gauge 4, and pressure governor 2, in order to the oily temperature and pressure power of control main fuel tank, transport pipe 11, one ends that are arranged in the main fuel tank 1 link to each other with filter cleaner 3 in the main fuel tank 1, one end communicates with each bearing support 13 through shunt 12; Drop tank 8 is provided with an oil pump 7, and the oil inlet pipe 9 of oil pump 7 communicates with each bearing support 13 through display device 10, and oil outlet tube communicates with main fuel tank 1, thereby forms an enclosed lubricating oil system.In order to prevent that the loss of lubricant oil makes the lubricant oil of main fuel tank keep certain capacity in the greasing, the oil pump 7 in the drop tank 8 is provided with a micro-compensator 6.To guarantee that main fuel tank 1 maintains stable pasta.
Concrete working procedure is as follows: when machine work, start oil pump 7, the oil inlet pipe 9 of the oil pump 7 sump oil And that contains impurity that constantly sucking-off is passed through after lubricating from each bearing 13 that communicates with it makes each bearing 13 form negative pressure, from showing the working condition that can be observed the oil inlet pipe that communicates with each bearing 10, the oil outlet tube of oil pump 7 and micro-compensator 6 constantly make main fuel tank keep stable pasta to main fuel tank 1 fuel feeding, and the transport pipe 11 that communicates with bearing support 13 is from main fuel tank 1, the cleaning lubricant oil that sucks through filter cleaner 3 and shunt 12 constantly feeds to each bearing support 13, thereby has guaranteed that each bearing support is among the oil lubrication of cleaning.
