Abstract
The invention discloses a kind of methods for improving liquid lower bearing service life, using oil-filling type structure, lubricating oil is directly injected into roller by the lubricating oil in top petrol tank by petroleum pipeline and hollow nip drum axis, and on the outside of the bearing of roller both ends, it is sealed using outside framework oil seal.Present invention ensures that the long-term operation of bearing, improves liquid lower bearing service life.
Description
Technical field
The present invention relates to a kind of methods for improving liquid lower bearing service life.
Background technique
It needs to impregnate for a long time in a liquid in certain special occasions bearings, the profit under this long-term liquid in the bearing of operation
Lubricating oil is lost very fast.Once lubricating oil lacks, bearing damage is necessarily caused, to influence the normal operation of equipment, is influenced
Production line production capacity and product quality, while also adding maintenance cost.
Summary of the invention
The purpose of the present invention is to provide a kind of raising liquid lower bearing service lifes of long-term operation for ensuring bearing
Method.
The technical solution of the invention is as follows:
A method of liquid lower bearing service life being improved, it is characterized in that: the lubricating oil using oil-filling type structure, in top petrol tank
Lubricating oil is directly injected into roller by petroleum pipeline and hollow nip drum axis, and on the outside of the bearing of roller both ends, using skeleton oil
Envelope is sealed.
The oilhole communicated with bored roll is provided on hollow nip drum axis.
Aperture on roller, the lubricating oil in top petrol tank are communicated by petroleum pipeline with the aperture, and nip drum axis is hollow or real
The heart, roller both ends bearing outside, is sealed using outside framework oil seal.
The present invention uses a kind of oil-filling type structure, and the lubricating oil in top petrol tank will be lubricated by petroleum pipeline and hollow axis
Oil is directly injected into the space between roller and axis, while being sealed on the outside of the bearing of roller both ends using oil sealing.It is equivalent to use
Roller, axis and the oil sealing at both ends form an enclosure space between roller and axis, which can only pass through the hole on axis
It is connected with the external world.
Nip drum of the present invention uses oil-filling type structure, and the lubricating oil in top petrol tank passes through petroleum pipeline and hollow nip drum axis
Lubricating oil is directly injected into roller, and on the outside of the bearing of roller both ends, it is sealed using common outside framework oil seal, structure letter
It is single.The setting of top petrol tank, it is ensured that lubricating oil pressure is greater than the pressure of extractant in extraction tank in roller, even if oil sealing occurs
Leakage, is also only likely to be lubricating oil and leaks into immersion liquid, bearing is in lubricating status always, it is ensured that the long period of bearing is transported
Row.Petroleum pipeline uses transparent plastic flexible pipe, is not only convenient for the lift work of nip drum, but also can be visually observed that the sealing of nip drum
Situation, convenient for replacement oil sealing or bearing in time.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the structural schematic diagram of one embodiment of the invention.
Fig. 2 is the partial enlarged view of Fig. 1.
Specific embodiment
Embodiment 1:
A method of liquid lower bearing service life being improved, using oil-filling type structure, the lubricating oil in top petrol tank passes through oil transportation
Lubricating oil is directly injected into roller 3 by pipe 1 and hollow nip drum axis 2, and the outside of roller both ends bearing 4, using outside framework oil seal 5 into
Row sealing.
The oilhole 6 communicated with bored roll is provided on hollow nip drum axis.There are also the circlips 7 to oil sealing positioning in figure.
Embodiment 2:
Aperture on roller, the lubricating oil in top petrol tank are communicated by petroleum pipeline with the aperture, and nip drum axis is hollow or solid, rolling
On the outside of the bearing of cylinder both ends, it is sealed using outside framework oil seal.Remaining is the same as embodiment 1.
Claims (4)
1. a kind of method for improving liquid lower bearing service life, it is characterized in that: the lubrication using oil-filling type structure, in top petrol tank
Lubricating oil is directly injected into roller by oil by petroleum pipeline and hollow nip drum axis, and on the outside of the bearing of roller both ends, using oil sealing
It is sealed.
2. the method according to claim 1 for improving liquid lower bearing service life, it is characterized in that: being opened on hollow nip drum axis
There is the oilhole communicated with bored roll.
3. the method according to claim 1 or 2 for improving liquid lower bearing service life, it is characterized in that: the oil sealing is bone
Frame oil sealing.
4. the method according to claim 1 for improving liquid lower bearing service life, it is characterized in that: aperture on roller, high-order
Lubricating oil in fuel tank is communicated by petroleum pipeline with the aperture, and nip drum axis is hollow or solid, roller both ends bearing outside, use
Oil sealing is sealed;Under working condition, roller is fixed form, and nip drum axis is the form of rotation.
