Description
Technical field
The present invention relates to a kind of device of technical field of bearings, specifically, what relate to is a kind of lub device of large diameter low speed sliding bearing machinery, is used for the manufacturing field of large-sized low-speed sliding bearing.
Background technique
Large-scale bearing is widely used in the large-scale rotary mechanism, as large-size ball mill, rotary kiln, Ship Propeling motor, Coolers etc.For the bearing that this type load is big, rotating speed is lower, set up the sliding protection of safe and reliable lubricant film, be the emphasis of Recent study.Low speed sliding bearing has been made big quantity research both at home and abroad, proposed some design proposals, comprising the mechanical lubrication of large-scale bearing and bearing selflubricating etc.At present, the large-scale bearing of uses such as large-size ball mill, rotary kiln, Ship Propeling motor, Coolers all adopts the lubricated mode of oil pump, with oil pump and distributor fuel feeding.This fuel system has only early trunk oil pump and distributor to guarantee work, and just can play lubrication under the reliable sealing situation.Because large-scale bearing oil pump or distributor in the process that reality is used may break down, and can cause the lubrication oil supply deficiency of sliding bearing, cause the life-span of bearing to reduce.
Find Chinese patent publication number: CN2384025, patent name: " bearing-lubricating device " by prior art documents.This patent relates to a kind of bearing-lubricating device, and this device is provided with oil inlet pipe and the return tube that communicates with bearing support on bearing cap, and oil inlet pipe communicates with transport pipe, and return tube directly communicates with fuel reserve tank, is provided with cooler in the fuel reserve tank.Though this device can make the bearing lubrication abundance, prolong bearing working life, yet its mechanical lubrication device application in the large-sized low-speed sliding bearing does not appear in the newspapers.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, a kind of lub device of large diameter low speed sliding bearing machinery is provided.Large diameter low speed sliding bearing of the present invention is meant: the diameter of axle is lower than 40 rev/mins sliding bearing greater than 500mm, rotating speed.Make it lubricated sufficient, prolong bearing working life.
The present invention is achieved by the following technical solutions, the present invention includes: bearing support, bearing shell, bearing cap, bilateral symmetry disc impeller, oil scraping plate, bearing cap are provided with the oil inlet pipe that communicates with bearing shell and oil returning tube and directly link to each other with fuel reserve tank on the bearing support.Bilateral symmetry disc impeller is the oil supply component that rotates with axle, is made of 18 equally distributed muscle, and bearing structure adopts bilateral symmetry machinery fuel feeding, guarantees the mechanical independent oil supply reliability under minimum speed and maximum inclination situation; The top of bearing shell is equipped with two symmetrical circular arc oil scraping plates, its effect be with in fuel reserve tank with on lubricant oil scrape into inflow pipeline, so that whole bearing shell and thrust face thereof are carried out film lubrication.
Be lower than 40 rev/mins, the diameter of axle sliding bearing at rotating speed greater than 500mm, for the thrust face that makes bearing bush obtains effective lubricating, the present invention takes the lubricated strategy of reverse fuel feeding: the lubricant oil that left side disc impeller and oil scraping plate are brought into offers the thrust face on the right; On the contrary, the lubricant oil that the right disc impeller and oil scraping plate are brought into offers the thrust face on the left side, obtains sufficient lubrication to guarantee bearing thrust face under situation about tilting, and forms continuous oil film.In order to guarantee the sufficient lubrication of mechanical oil supplying device, the present invention need test the fuel delivery of low-speed big-diameter sliding bearing.
Enforcement of the present invention has solved a domestic and international technical barrier at large-sized low-speed self-lubricating plain bearing mechanical lubrication technical field, utilizes the present invention can improve the fuel system of large-scale bearing.The oil supplying device that utilization is rotated with axle, can form the film lubrication of continous-stable, thereby overcome the defective of the outer power fuel feeding (oil pump feed) of original utilization, improved the reliability of bearing, avoided main equipments such as large-size ball mill, rotary kiln, Ship Propeling motor and Coolers because the loss that bearing fault causes.

Embodiment
As shown in Figure 1, the present invention includes: bearing support 1, bearing shell 2, bearing cap 3, bilateral symmetry disc impeller 4, oil scraping plate 5, bearing cap 3 are provided with the oil inlet pipe 6 that communicates with bearing shell 2 and link to each other with oil returning tube 7 fuel reserve tanks 8 direct and on the bearing support.As shown in Figure 2, symmetrical disc impeller 4 is the oil supply components that rotate with axle, is made of 18 equally distributed muscle, and bearing structure adopts bilateral symmetry machinery fuel feeding, guarantees the mechanical independent oil supply reliability under minimum speed and maximum inclination situation; The top of bearing shell 2 is equipped with two symmetrical circular arc oil scraping plates 5, its effect be with in fuel reserve tank 8 with on lubricant oil scrape into inflow pipeline 6, so that whole bearing shell and thrust face 9 thereof are carried out film lubrication.
Bilateral symmetry disc impeller 4 is the oil supply components that rotate with axle, is made of 18 equally distributed muscle, to form continuous band oil cavity.The bilateral symmetry disc impeller 4 that is installed on the main shaft rotates with axle, utilize 18 equally distributed muscle will be stored in after lubricant oil in the fuel reserve tank 8 take bearing shell 2 tops to, the oil scraping plate 5 that is installed in the bearing shell top is scraped into 6 pairs of bearing shells of oil inlet pipe and thrust face 9 thereof and is lubricated.
The present invention takes reverse fuel feeding lubricated: the lubricant oil that left side disc impeller 4 and oil scraping plate 5 are brought into offers the thrust face on the right; On the contrary, the lubricant oil that the right disc impeller 4 and oil scraping plate 5 are brought into offers the thrust face on the left side, obtains sufficient lubrication to guarantee bearing thrust face under situation about tilting, and forms continuous oil film.Thereby overcome the defective of the outer power fuel feeding (oil pump feed) of original utilization, improved the reliability of bearing, avoid main equipments such as large-size ball mill, rotary kiln, Ship Propeling motor and Coolers because the loss that bearing fault causes.
At the diameter of axle is the test of the large-scale self-lubricating plain bearing fuel delivery of low speed of 700mm, and the present invention adopts easy device that the mechanical lubrication fuel delivery is tested.Being 40 degrees centigrade in ambient temperature is the environment of 60%RH with humidity, fuel delivery to 20 rev/mins, 30 rev/mins and 40 rev/mins is tested respectively, its concrete method of measurement is: keep constant ambient temperature (40 degrees centigrade) and humidity (60%RH), utilize frequency variator to regulate the rotating speed (being respectively 20 rev/mins, 30 rev/mins and 40 rev/mins) of experiment axle, and carry out after rotating speed determines with tachometer, measure 5 minutes fuel delivery, calculate the fuel delivery of per minute then.Whole experiment device is set to heeling condition (30 degree tilt), the ambient humidity that keeps constant 40 degrees centigrade of ambient temperatures and 60%RH, utilize with the identical method of horizontal survey fuel delivery, measure the lubricating condition of single disc impeller under tilt condition, and compare with the minimum fuel delivery of bearing shell actual demand, improve the product percent of pass of bearing.The diameter of axle that table one is measured for part is the large-scale self-lubricating plain bearing fuel delivery of the low speed data of 700mm.
