Abstract
The utility model relates to an intelligent oil film bearing of a rolling mill. The intelligent oil film bearing comprises an oil film bearing of a rolling mill, and a miniature displacement sensor radially arranged on the outer end of the oil film bearing, wherein a signal lead-out wire of the displacement sensor is led out of a bearing box of the oil film bearing and is connected with a secondary instrument through a preamplifier. The intelligent oil film bearing can achieve online thickness detection. If support rollers and roller bearings are located and arranged intelligently in pairs, the mounting concentricity of two bearings of the rollers can be determined according to the thicknesses of oil films on both sides of the bearings, thereby achieving online mounting accuracy detection of the bearings and improving the quality of rolled products. The intelligent oil film bearing can protect the sensor, and the signal line can be extracted out of the bearing box easily. The sensor is arranged close to the bearing end section, where the oil film of the bearing has lower pressure close to the external pressure of the end section, thereby facilitating sealing.
Description
Technical field
The utility model relates to a kind of oil film bearing for intelligent rolling mill, is former filmatic bearing of press to be carried out intelligence transform, and on special position, displacement transducer of ingenious installation is realized the oil film bearing for intelligent rolling mill of online detection Lubrication Film Thickness.Belong to heavy duty industrial and Iron And Steel Industry field, be mainly used in the milling train industry.
Background technique
Filmatic bearing of press is the critical piece of Iron And Steel Industry milling train.The quality of filmatic bearing of press directly influences the life-span and the life cycle of back-up roll, roll and milling train.The variation of filmatic bearing of press oil slick thickness has a direct impact rolling quality of product, the oil slick thickness of filmatic bearing of press can not onlinely detect in the past, the installation precision of back-up roll, roll two bearings can only lean on skilled labour's experience to guarantee, handles complicated when the milling material quality problems take place.Invented the utility model at above situation---oil film bearing for intelligent rolling mill.Realize the online detection of oil slick thickness of filmatic bearing of press, back-up roll, the paired location and installation device of rolling bearing, can also realize detecting the installation quality of filmatic bearing of press, according to the debugging that detects oil slick thickness data and related components, can change Lubrication Film Thickness, improve the milling material quality.
The model utility content
The purpose of this utility model is to provide a kind of intelligent rolling mill oil film of realizing online detection Lubrication Film Thickness.
For achieving the above object, the utility model adopts following technical proposals:
A kind of oil film bearing for intelligent rolling mill, comprise a filmatic bearing of press, its feature is radially installed a small-sized displacement transducer in the outer end of described filmatic bearing of press, the signal lighting outlet of described displacement transducer is drawn outside the bearing housing that contains described filmatic bearing of press, is connected to secondary meter through external preamplifier.
The mounting structure of above-mentioned small-sized displacement transducer is: have a radial screw bore and described small-sized displacement transducer to revolve in the outer end of described filmatic bearing of press and join, there is the inductive head of the ccontaining small-sized displacement transducer of pit the lower end of this radial screw bore, and there is a mounting groove upper end, and a nut screws with small-sized displacement transducer upper end bolt in this mounting groove.
The mounting structure of above-mentioned signal lighting outlet is: the inner of described signal lighting outlet links to each other with described small-sized displacement transducer, described filmatic bearing of press outer end is sent out has an inclined hole to be communicated with the inner chamber of described mounting groove and described bearing housing on the orchid, there is a horizontal hole to make the inner chamber and extraneous connection of bearing housing on the described bearing housing, described signaling line enters the bearing housing inner chamber from mounting groove through inclined hole, draw the external world through horizontal through hole again, have a sealing plug that it is sealed in the horizontal hole outer end, the sealing head was passed through in described signal lighting outlet sealing.
The utility model compared with prior art, have following conspicuous essential characteristics and advantage: the utility model can be realized the online detection of roller-mill bearing oil slick thickness, if back-up roll, the paired intelligent location and installation of rolling bearing, then pass through the data of both sides Lubrication Film Thickness, judge the concentricity that the roll two bearings is installed, promptly can be implemented in the installation precision that line detects bearing, improve the milling material quality.The utility model is protected sensor, and signaling line is drawn bearing housing again easily.Sensor is installed near the bearing end, and the oil film pressure of bearing is less herein, near the pressure of outside, bearing end, and sealing easily.

Embodiment
When the wall thickness of filmatic bearing of press 2 during greater than 20mm, can realize the filmatic bearing of press intellectuality, promptly a small-sized displacement transducer 5 accurately is installed at nearly flange end.1 is bearing support, and 3 is tapered sleeve.Specific practice is that installation position displacement sensor sense 5 is to guarantee testing precision at the required tapped hole of the nearly flange end processed sensor of filmatic bearing of press 25, gets rid of and disturbs, and at bearing 2 inner hole surface, 5 center positions of sensor, the pit 9 of ream inductive head upwards.In order to prevent that displacement transducer 5 from moving, tightening nut 4. is installed.Therefore the tapped hole top is processed with the mounting groove 10 of nut 4.For drawing sensor signal lighting outlet 6, beat the through hole 12 of level of processing on the suitable position of inclined hole 11 and bearing housing 7 respectively at bearing 2 flange ends, the signaling line 6 of sensor is drawn bearing 2 by inclined hole 11, draws bearing housing 7 by horizontal hole 12 again, then with sealing plug 8 sealing horizontal holes.So just finished the mounting arrangements of displacement transducer 5.Concrete mounting type is seen Fig. 1, Fig. 2.Displacement transducer 5 is installed in the nearly flange end of bearing, paraxial socket end face, the oil film pressure of bearing is less herein, near the pressure of bearing end outside, sealing easily, the screw thread of sensor 5 can form sealing, oil sealing in bearing.From Fig. 1, Fig. 2 as can be seen the signal lighting outlet 6 of displacement transducer 5 be easy to draw bearing housing 7.As long as the initial position of sensor 5 is adjusted, determine primary data.By external preamplifier and secondary meter and primary data, just can determine to be installed in the filmatic bearing oil slick thickness on back-up roll, the roll, realize that online inspection detects the oil slick thickness of filmatic bearing of press.If back-up roll, the paired intelligent location and installation of rolling bearing then by the data of both sides Lubrication Film Thickness, are judged the concentricity that the roll two bearings is installed.Installation precision that both can online detection bearing.The intellectuality of realization filmatic bearing of press.
