Abstract
The utility model discloses a sensor box, belonging to a special measuring device for metal tandem rolling production lines. A displacement sensor (2) is arranged in a box body (1) in which a main shaft (6) and a pair of gears (3), (4) are also arranged, the plastic gear (3) having self-lubricating and damping functions is arranged on a shaft of the displacement sensor (2), the main shaft (6) is supported in the box body (1) by two bearings, the end of the main shaft is provided with the metal gear (4) engaged with the gear (3), the other end of the main shaft (6) is extended out of the box body (1) and is connected with a main machine (7), and a damper (5) is arranged under the box body (1). The sensor box makes the displacement sensor work under the condition approximate to a laboratory and enhances the working reliability and the service life of the sensor.
Description
The utility model relates to a kind of Sensor box, and specifically a kind of displacement transducer case belongs to the measurement mechanism that is specially adapted for the metal continuous rolling production line.
On various continuous rolling production lines,, on the various work mechanisms of main rolling line, be equiped with a large amount of displacement transducers, and the reliability of working sensor has determined that can automatic control system operate as normal for realizing comprehensive automation control.At present, these sensors are directly installed on the main frame mostly, the working environment very severe, particularly for hot continuous rolling production line, sensor will bear high temperature simultaneously, water vapour, impact shock when effect of dust and main frame running, can't guarantee the reliability of working sensor, in addition, the formed static(al) of sensor installation deviation also influences the reliability of working sensor, for this reason, taked in the prior art in the sensor manufacturing, to strengthen structural behaviour, adopt elasticity not have measures such as torsional angle shaft coupling installing,, all fail to address the above problem comprehensively though obtained some effects.
The purpose of this utility model provides a kind of Sensor box that can make displacement transducer be in approaching breadboard condition work, with the reliability and the service life of improving its work, guarantees the automatic control system operate as normal.
The purpose of this utility model is to realize like this.
Displacement transducer is installed in the casing, and main shaft and a pair of pitch wheel also are housed in the casing; Plastic gear with self-lubricating and shock-absorbing function is installed on the axle of displacement transducer; Main shaft is bearing in the casing by two bearings, and the end is equipped with the metal gear that is meshed with plastic gear on the displacement transducer axle, and the other end of main shaft stretches out casing and main frame links; Damper is housed below the casing.
The plastic gear that is installed on the displacement transducer axle can be made by superhigh molecular weight polyethylene is rare, also can be made by polytetrafluoroethylene (PTFE).
Damper is rubber absorbers.
On the casing inner main axis fan is housed.
Introduce embodiment of the present utility model below in conjunction with accompanying drawing.
Accompanying drawing is the structural representation of the utility model Sensor box.
As shown in the figure, the utility model Sensor box mainly is made up of casing 1, displacement transducer 2, gear 3,4, damper 5, main shaft 6 and fan 8.Sensor 2, main shaft 6 and gear 3,4 all are contained in the casing 1.Gear 3 is installed on the axle of sensor 2 for having the polytetrafluoroethylene (PTFE) gear of self-lubricating and shock-absorbing function.Main shaft 6 is bearing in the casing 1 by two bearings, and the end is equipped with the metal gear 4 that is meshed with polytetrafluoroethylene (PTFE) gear 3 on 2 of the displacement transducers.The other end of main shaft 6 stretches out casing 1 and links with main frame 7.Rubber absorbers 5 are housed below the casing 1.In the casing 1, on the main shaft 6 fan 8 is housed, the heat that produces when distributing sensor 2 work.For lower-powered sensor, also can adopt the method for on casing 1, opening the heat loss through convection hole to solve heat dissipation problem.
After Sensor box installs in advance, main shaft 6 is linked by shaft coupling and main frame 7.The rotatablely moving through main shaft 6 of main frame 7 during work, the speed ratio that is accurately reached displacement transducer 2, two gears 3,4 by gear 3,4 can require to select according to control.At running or the static additional force that is caused, and born by main shaft 6 entirely by influence such as main frame 7 shaking forces by manufacturing, installation deviation and bearing clearance etc. for main frame 7.And be installed on the gear with self-lubricating and shock-absorbing function 3 on 2 of the displacement transducers, can guarantee further that vibrations on 7 in the main frame do not pass on 2 of the displacement transducers.The damper 5 that casing 1 is installed below is used to absorb the vibration that the main frame base transmits.
The advantage that the utility model compared with prior art has is: displacement transducer is pacified Be loaded in the casing and the surrounding environment isolation, make sensor worker under near the condition in laboratory Do functional reliability and the service life of having improved sensor. This Sensor box also has peace The dress required precision is low, and construction is simple, can pre-install and the advantage such as integral replacing.
Claims (4)
1. a Sensor box has displacement transducer, it is characterized in that: displacement transducer (2) is installed in the casing (1), and main shaft (6) and a pair of pitch wheel (3), (4) also are housed in the casing (1); Plastic gear (3) with self-lubricating and shock-absorbing function is installed on the axle of displacement transducer (2); Main shaft (6) is bearing in the casing (1) by two bearings, and the end is equipped with the metal gear (4) that is meshed with plastic gear (3) on displacement transducer (2) axle; The other end of main shaft (6) stretches out casing (1) and links with main frame (7); Damper (5) is housed below the casing (1).
