Description
Technical field
The invention belongs to temperature testing equipment technical fields, and in particular to a kind of nothing applied to filmatic bearing running temperature
Line monitoring device.
Background technique
Filmatic bearing is a kind of bush(ing) bearing using lubricating oil as lubricant medium, filmatic bearing it is many kinds of,
It is widely used in milling train, steam turbine, generating set, ball mill, fan bearing, astronomy, Aeronautics and Astronautics equipment etc..
Large-scale, high speed, heavy duty, continuous, automatic is mainly characterized by due to Modern Rolling Mill, especially there is template, plate thickness
The large plate of automatic control, band tandem mill mostly use filmatic bearing, apply on milling train as workroll bearing or bearing
Roller bearing is referred to as filmatic bearing of press, this class bearing substantially belongs to low-speed heave-load, carries in middling speed or heavy-duty bearing.So
Filmatic bearing of press is that one of maximum bearing is carried in filmatic bearing.
Its working principle is that: during the rolling process, due to the effect of roll-force, force roll shaft axle journal to move, oil film
The center of bearing centre and axle journal generates bias, so that the gap between filmatic bearing and axle journal is formd two regions, one is cried
Diverging region (becomes larger) along axle journal direction of rotation gap, another cries region of convergence (being gradually reduced along axle journal direction of rotation).When
The axle journal of rotation is there is the lubricating oil of viscosity to bring region of convergence into from diverging region, from large to small along axle journal direction of rotation bearing clearance,
A kind of oil film wedge is formed, makes to generate pressure in lubricating oil.
In enterprise, steel mill cold rolling workshop, milling train mostly uses filmatic bearing, in order to reach the duration stability of production, leads to
The temperature of filmatic bearing can be often monitored, avoid the filmatic bearing of milling train from causing to seize because temperature is excessively high, directly affect
Production, in the actual operation process, it will usually following problems occur:
1, due to the structural particularity of filmatic bearing, the distance from bearing seating face to temperature measuring point is larger, common to survey
Warm device is unable to reach temperature measuring point, leads to the temperature value inaccuracy of measurement；
2, it in the process of running due to filmatic bearing, is influenced by roll-force, roll shaft axle journal is caused to shift, temperature is surveyed
The position of amount point is uncertain, and the distance of temperature measuring point to the bearing seating face of different filmatic bearings is unequal, existing thermometric dress
It sets fitting depth to fix, cannot achieve the adjustment of measurement position；
3, it due to the particularity of filmatic bearing working environment, needs to be sealed device for monitoring temperature, common thermometric dress
The sealing ring position set easily shifts, and causes the leakproofness of temperature measuring equipment poor；
4, it when common temperature measuring equipment is mounted on filmatic bearing, is sealed using rubber gasket, rubber gasket is strong
It is poor to spend, and is easily damaged during the installation process, influences the leakproofness between temperature measuring equipment and filmatic bearing, reduces sealing effect.
5, existing temperature measuring equipment is connected using wired mode, and in actual production, the disassembly of bearing, replacement frequency are non-
Chang Gao causes wired temperature measuring equipment spoilage also very high, so not very practical.
