Abstract
The utility model relates to an automatic lubricating device for the large gear of a coal mill, and comprises a pneumatic device, a hydraulic device and a time control device. The utility model is mainly characterized in that the automatic lubricating device is provided with a jetting board. An oil hole and a wide hole are arranged in the valve body of the jetting board. The oil hole is provided with a one-way valve. A nozzle is fixed on the valve body. The nozzle is provided with an oil passage and a wide passage which are respectively communicated with the oil hole and the wide hole in the valve body. The utility model has the advantages of automatic oil jetting lubrication, no pollution, low labour intensity and good lubricating effect, adopts gear lubrication oil as lubricant, and can prolong the service life of gears.
Description
The utility model belongs to a kind of lubricating fitting of coal pulverizer gearwheel.
Present Power Plant in China, Steel Ball Coal Mill gearwheel lubricated adopts machine oil to add pitch prill and makes oiling agent, and lubricated by manually smearing on the gearwheel, labor intensity is big, befouling environment, and lubrication effect is undesirable, has reduced the working life of big small gear.
The purpose of this utility model provides a kind of coal pulverizer gearwheel automatic lubricator, adopts gear lubricant to make oiling agent, automatic splash lubrication, and non-environmental-pollution, labor intensity is low, and high lubricating effect prolongs working life of big small gear.
The purpose of this utility model is achieved in that it comprises Pneumatic actuator, hydraulic pressure installation, time-controlling arrangement, the technological scheme main points are to be provided with jet tray, oilhole and wind hole are arranged in the valve body of jet tray, one-way valve is housed in the oilhole, affixed nozzle on the valve body, oil duct and air channel are arranged in the nozzle, and communicate with oilhole and wind hole in the valve body respectively.
The utility model has the advantages that: adopt gear lubricant to make oiling agent, automatic splash lubrication, non-environmental-pollution, labor intensity is low, and high lubricating effect can prolong the working life of gear, and saves lubricant oil 80%.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is Pneumatic actuator of the present utility model, hydraulic pressure installation, time-controlling arrangement and the schematic representation that connects of jet tray.
Fig. 2 is the external structure schematic representation of jet tray.
Fig. 3 is the A-A sectional view of Fig. 2.
Fig. 4 is the B-B sectional view of Fig. 2.
Fig. 5 is the C-C sectional view of Fig. 4.
Fig. 6 is the plan view of valve body.
Fig. 7 is the time control circuit schematic diagram.
See Fig. 1-7, concrete structure of the present utility model is as follows: utilize the Pneumatic actuator of prior art, it provides the jet tray air, and air pump 7 is arranged, and by pipeline serial connection pressure regulator valve 6 and solenoid valve 5, its output terminal connects the intake opening 24 of jet tray by pipeline.Utilize the hydraulic pressure installation of prior art, it provides jet tray lubricant oil, and it has gear pump 1, the gear pump 1 inlet source of giving a dinner for a visitor from afar, and outlet is by pipeline serial connection one-way valve 2 and throttle valve 3.The oil inlet hole 25 of hydraulic pressure installation output termination jet tray.Hydraulic pressure installation, Pneumatic actuator all are connected (the control circuit schematic diagram is seen Fig. 7) with the SCR control device of prior art.Jet tray has valve body 4, and 4 nozzles are installed on the valve body 4.Wind hole 23 and oilhole 22 are arranged in the valve body 4. Oilhole 22 and 4 unidirectional valve pockets are communicated with, and valve seat 21 is housed in each valve pocket, and the nonreturn valve core 19 that has valve opening and sealing cone 20 is contained on the valve seat.The one end assembling spring 18 of nonreturn valve core 19, spring 18 is installed on the packing ring 17.Provide auxiliary hole stifled 9 among Fig. 3.Annular wind chamber 15 is arranged at nozzle core 8 bottoms of nozzle, and the wind hole exits in this chamber and the valve body 4 is communicated with chamber built-in ring 16.Annular wind chamber 15 communicates with three air channels 10 that are the distribution of fan type.There is oil pocket 14 in the central authorities of nozzle core 8 bottoms, and the oilhole outlet in this chamber and the valve body 4 is communicated with, chamber built-in ring 16, and oil pocket 14 communicates with oil duct 11.Nozzle core 8 is fixed by bolts on the valve body 4.The upper end suit end cap 12 of nozzle core 8, and be fixed on nozzle core 8 by gland 13 scyewed joint.
Working procedure: lubricant oil enters the oilhole of valve body 4 after the hydraulic pressure installation supercharging, and backs down nonreturn valve core, from the oil duct ejection of nozzle core 8; The wind hole that Pneumatic actuator provides pressure wind to enter valve body 4, the pressure wind that pressure wind blows out from three air channels of nozzle core 8 blows out nozzle, and is injected on the gear surface at nozzle core end mixed aerosol.Because the SCR control device is arranged, can regularly carry out automatic jet lubrication to coal pulverizer gearwheel surface.
