Abstract
A magnet-set type supercharger speed measuring locking device capable of measuring the rotor rotating speed of the diesel engine supercharger of the rail way inner combustion engine vehicle and locking the working wheels. A concave hole is drilled on the end face of a locking nut or a bolt whose shape and size are corresponding to those of the supercharger working wheels. The concave hole is coated with glue inside and beset with a column-shaped magnet which is engaged and integrated with the corresponding nut or the bolt to form the magnet-set type supercharger speed measuring locking device, which can not only lock the working wheel but also rotate with the rotor to generate a rotating magnetic field. The sensor generates pulses according to the change of the magnetic change to measure the rotating speed of the supercharger rotor. According to the type of the supercharger, the device is divided into the two types, specifically external screw hex bolt and the internal screw column-shaped nut, that can be engaged with the sensor to measure the rotating speed of the supercharger rotor with safety and precision, further diagnose the malfunction existed in the supercharger and reduce the occurrence of the rail way inner combustion engine vehicle accident.
Description
Affiliated technical field
The utility model relates to and a kind ofly can satisfy beeliner diesel pressure booster rotor speed and measure and can carry out fastening device to active wheel again.
Background technology
At present, known beeliner diesel pressure booster failure rate is higher, and when supercharger broke down, locomotive can not continue operation, sometimes also can breaking out of fire and injury passenger's accident, so the supercharger fault is diagnosed in advance very important.And measure the supercharger rotor rotating speed is the key that addresses this problem, and has only and measures rotor speed accurately, just can judge the duty of supercharger.And intrinsic supercharger active wheel set nut does not have magnet, just the end face at nut processes a chase or boss, when surveying rotating speed with contactless band Magnetic Sensor, axially the measuring distance maximum can only reach 2mm, be difficult to adjust to suitable position during sensor installation, because rotor also has the axial internal clearance of 0.5mm, even at rig-testing, also often sensor takes place and measured object connects mill, the accident of damage supercharger.Supercharger costs an arm and a leg, in case the economic loss that has an accident is huge.Because supercharger rotor is in airtight housing, working temperature is more than 100 ℃, air pressure can reach more than the 300KPa, sensor installation site limitation is big, various sensors all can not satisfy the demand of measuring rotor speed, hold as photoelectric sensor and can't stand high temperature, and luminous point can't be installed etc., fail to realize so measure the supercharger rotor rotating speed always, become the technical barrier of supercharger fault diagnosis with car.
Summary of the invention
Can not safely, accurately measure the problem of rotating speed in order to solve existing supercharger rotor, the utility model provides a kind of edge magnetic-type supercharger locking device that tests the speed, this edge magnetic-type supercharger tests the speed locking device not only can the same fastening active wheel with original nut or bolt, the speed that active wheel is rotated obtains test, promptly measures the rotating speed of supercharger rotor.
The technical scheme that its technical matters that solves the utility model adopts is: get out pit on the end face of shape and structure and corresponding set nut of supercharger active wheel or bolt, gluing is bumped into cylinder-shaped magnet in the pit, cylinder-shaped magnet is bumped into behind the pit formation one that matches with nut or bolt, constitutes the edge magnetic-type supercharger locking device that tests the speed.Because supercharger model difference, the fastening means that is adopted is also different, and this device is divided into two kinds of external thread hex bolts shape and internal thread barrel nuts.The speed probe of selecting magneto sensor to make is installed on the air-breathing curved neck fabrication hole, can accurately measure the supercharger rotor rotating speed.According to the requirement of sensor, can be bumped into one, two or more magnet to magnetic field intensity and pulse.It is characterized in that: cylinder-shaped magnet matches with pit on supercharger active wheel set nut or the bolt and is connected.
The beneficial effects of the utility model are can produce magnetic field on tested object, when detected supercharger rotor rotates, magnet also rotates thereupon, form rotating magnetic field, the sensor of Pei Heing both can have been measured the rotating speed of supercharger rotor according to the cycle that rotating magnetic field changes with it.Because testee has had magnetic field, can make sensor distance testee spacing increase to 5-15mm, sensor does not connect mill with testee when guaranteeing to detect, and has improved security and accuracy that supercharger speed is measured, and is simple in structure.

Embodiment
In Fig. 1, magnet (3), (4) are installed in the nut of clamping screw (5), are glued, and constitute the external thread locking device that tests the speed.Active wheel (6), sliding bearing (7), exhaust gas turbine (10) are installed in respectively on the armature spindle (8), and active wheel (6) is by on the fastening armature spindle of clamping screw (5), and these parts constitute rotor to be formed, and is called for short rotor during narration.Exhaust gas turbine (10) drives rotor high speed rotating in supporting base (9) under the waste gas effect that diesel engine is discharged, magnet together rotates with rotor, forms rotating magnetic field.Sensor (1) is fastened in the threaded hole of the air-breathing curved neck of supercharger (2), and sensor end face and locking device distance (11) can be adjusted at 5-15mm and fix, and has both guaranteed the accuracy of measuring, and does not contact with measured body in the time of can guaranteeing to measure again.When the magnet that is bumped into (3) and (4) opposite polarity directions, the rotor revolution moves a week, and sensor is an exportable square wave, through the conversion of tachometer gage, can demonstrate the rotating speed of supercharger rotor.When the magnet that is bumped into (3) and (4) when polar orientation is identical, the rotor revolution moves a week, and sensor is exportable two square waves, is bumped in the groove after adjusting pole orientation as required during assembling.
In Fig. 2, magnet (3), (4) are installed in the nut of set nut (13), are glued, and constitute the internal thread locking device that tests the speed.Sensor (1) is fastened in the threaded hole of supercharger kuppe (12).Other structures and effect are described identical with Fig. 1.Since supercharger model difference, the locking mode difference of active wheel, the installation position difference of sensor, but method of testing is identical.
Fig. 3, Fig. 4 are in order more clearly to express the test the speed geometric configuration of locking device of external thread.
