Abstract
The utility model discloses a hydrostatic lubrication device for a middle-high pressure oil film. The hydrostatic lubrication device comprises a ball valve arranged at an oil inlet, wherein an oil sucking filter and a gear pump are sequentially connected to the oil outlet of the ball valve; a direct-acting overflow valve is connected between the oil outlet of the ball valve and an oil outlet of the gear pump; a pressure gauge and a high-pressure ball valve are also connected to the oil outlet of the ball valve. The hydrostatic lubrication device disclosed by the utility model has the advantages of simple structure, lightness, small occupied space, convenience in mounting and use and wider application range. Middle-high pressure hydrostatic lubrication of a bearing at the start state, the low-speed operation state and the break state of a large-size main motor is realized; the defects of hydrodynamic lubrication are overcome.
Description
Technical field
The utility model relates to a kind of mesohigh oil film hydrostatic lubrication device.
Background technique
Large-scale main motor shaft holds the ring-oil of adopting more, the oil ring bottom that namely is enclosed within on the axle journal is immersed in the oil sump, frictionally drives the oil ring rotation, thereby oil brought in the bearing be lubricated, the method is applicable to that rotating speed is at the horizontal axis of 50 ~ 300r/min scope, rotating speed is high again, and oil ring will acutely be beated on axle; Rotating speed is too low, then the fuel delivery deficiency.The focus pressure circulating lubrication mode of adopting is also arranged.But some main motor is because of special work condition environment, and above-mentioned lubricating system still can not meet the demands fully, the cold rolling unit master motor rolling as monovolume, there are frequent starting, low cruise, braking, the low formation oil film that is difficult for of rotating speed causes dry friction, causes bearing wear and even scaling loss.Need to increase and use hydrostatic lubrication to remedy lack of lubrication.
Summary of the invention
The purpose of this utility model is to provide a kind of mesohigh oil film hydrostatic lubrication device, lubrication motor bearing effectively, high working efficiency.
The purpose of this utility model is to realize like this, a kind of mesohigh oil film hydrostatic lubrication device, comprise the ball valve that is installed in the filler opening place, the oil outlet of ball valve is connecting oil suction filter and gear pump successively, be connected direct-acting overflow valve between the oil outlet of ball valve and the oil outlet of gear pump, the oil outlet of ball valve is also connecting a pressure gauge and a high-pressure ball valve.
When the utility model had been realized large-scale main electric motor starting, low cruise, braking, the mesohigh hydrostatic lubrication of bearing had remedied the deficiency of hydrodynamic lubrication.Install lightly, it is little to take up room, and is convenient to install and use, and Applicable scope is wider.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is linkage structure schematic representation of the present utility model.
Embodiment
A kind of mesohigh oil film hydrostatic lubrication device, comprise the ball valve 1 that is installed in the filler opening place, as shown in Figure 1, the oil outlet of ball valve 1 is connecting oil suction filter 2 and gear pump 3 successively, be connected direct-acting overflow valve 6 between the oil outlet of the oil outlet of ball valve 1 and gear pump 3, the oil outlet of ball valve 1 is also connecting a pressure gauge 4 and a high-pressure ball valve 5.
