Description
Technical Field
The utility model belongs to the technical field of the roller bearing is lubricated, concretely relates to thin oil lubrication structure.
Background
The press rolls currently marketed and used are a lubrication system lubricated with grease. Because lubricating grease is more viscous, so to need lubricated bearing packing not very abundant, again the high temperature that produces in the granulation machine work can make lubricating grease dry and knot, so reduced compression roller bearing's life.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a thin oil lubrication structure to solve the problem of proposing among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: a thin oil lubrication structure comprises an eccentric shaft, a bearing sleeved on the eccentric shaft and a pinch roller sleeved on the bearing; an oil duct extending along the radial direction of the eccentric shaft is arranged in the eccentric shaft; the oil inlet is formed in one end of the eccentric shaft, the through hole is formed in the eccentric shaft, the oil outlet is formed in the outer surface wall of the end, far away from the oil inlet, of the eccentric shaft, the oil outlet is located outside the bearing, and the oil inlet, the through hole and the oil outlet are communicated with the oil duct.
Preferably, bearing caps are arranged at two ends of the bearing, oil seals are arranged on the bearing caps, and the oil seals are located inside the bearing.
Preferably, the bearing is provided with a positioning sleeve corresponding to the oil seal, and the positioning sleeve is sleeved on the outer surface wall of the eccentric shaft.
Preferably, the outer end of the bearing cover is provided with a round nut, and the round nut is in threaded connection with the bearing cover.
Preferably, the bearing cover is connected with the pressing wheel through a bolt.
Compared with the prior art, the beneficial effects of the utility model are that: the thin oil lubricating structure is reasonable in structure and simple to install, the bearing can be fully lubricated, the service life of the compression roller is prolonged, the production efficiency is improved, and the capital investment and the maintenance cost are also reduced.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. an eccentric shaft; 2. oil sealing; 3. a bearing cap; 4. a bearing; 5. a pinch roller; 6. a bearing spacer; 7. a positioning sleeve; 8. a round nut; 9. an oil inlet; 10. and an oil outlet.
Detailed Description
The present invention will be further described with reference to the following examples.
The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention. The condition in the embodiment can be further adjusted according to concrete condition the utility model discloses a it is right under the design prerequisite the utility model discloses a simple improvement of method all belongs to the utility model discloses the scope of claiming.
Referring to fig. 1, the present invention provides a thin oil lubrication structure, which includes an eccentric shaft 1, a bearing 4 sleeved on the eccentric shaft 1, and a pressing wheel 5 sleeved on the bearing 4; an oil duct extending along the radial direction of the eccentric shaft 1 is arranged in the eccentric shaft 1; an oil inlet 9 is opened to the one end of eccentric shaft 1, has seted up the perforation on the eccentric shaft 1, and eccentric shaft 1 keeps away from the one end exterior wall of oil inlet 9 and has seted up oil-out 10, and oil-out 10 is located the outside of bearing 4, and oil inlet 9, perforation and oil-out 10 all communicate with the oil duct.
In the scheme, the thin oil enters the oil channel of the eccentric shaft 1 through the oil inlet 9, and after entering the bearing 4 through the through hole to lubricate the bearing 4, the thin oil in the oil channel returns to the oil channel through the through hole and flows out through the oil outlet 10, so that the roller bearing can be effectively lubricated, and the service life of the roller is prolonged.
Specifically, both ends of the bearing 4 are provided with bearing covers 3, an oil seal 2 is arranged on the bearing covers 3, and the oil seal 2 is positioned inside the bearing 4; by arranging the oil seal 2 on the inner side of the bearing cover 3, two ends of the bearing 4 can be effectively sealed, and the oil leakage phenomenon is avoided.
Specifically, a positioning sleeve 7 corresponding to the oil seal 2 is arranged on the bearing 4, and the positioning sleeve 7 is sleeved on the outer surface wall of the eccentric shaft 1; through setting up position sleeve 7, give oil blanket 2 an installation strong point, the installation of the oil blanket 2 of being convenient for.
Specifically, the outer end of the bearing cover 3 is provided with a round nut 8, and the round nut 8 is in threaded connection with the bearing cover 3; through setting up round nut 8, press the outer end at oil blanket 2 with bearing cap 3 through round nut 8 to make its structure more stable.
Specifically, the bearing cover 3 is connected with the pinch roller 5 through a bolt; the bearing cover 3 is connected with the pinch roller 5 through bolts, so that the bearing cover 3 is fixed with the pinch roller 5.
The utility model discloses a theory of operation and use flow: when the lubricating device is used, thin oil is introduced into the oil duct of the eccentric shaft 1 through the oil inlet 9, enters the bearing 4 through the through hole, lubricates the bearing 4, enters the oil duct through the through hole after flowing through the thin oil in the bearing 4, and flows out through the oil outlet 10, so that the lubricating work of the compression roller bearing is completed.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
