Abstract
The utility model relates to an electrical signal output device of a mechanical vibration-testing meter, which is used for measuring mechanical vibration. The utility model is realized through adding an electrical signal output device on the basis of a Gelger type vibration meter. The electrical signal output device is composed of a metal sheet, an electric eddy current sensor, a changer, and an electric eddy current vibration meter. The metal sheet can be stuck on one end of the push rod of the Gelger type vibration meter and can be fixed at the connecting point of the stylus pen and the push rod of the Gelger type vibration meter. The electrical signals output by the electrical signal output device can be recorded and treated by various electronic instruments. The utility model can be used for the measurement of the torsional vibration of medium speed engines and low speed engines.
Description
The present invention relates to a kind of improvement of vibration measurement device.
The mechanical type vialog is a kind of mechanical vibration measurement mechanism that people generally adopt at present.Concerning the twisting vibration relevant with the present invention measured, existing metering system can reduce two kinds: a kind of is the metering system that adopts principle of inertia, promptly the belt pulley of torsiograph directly or by belt by tested turning axle driven rotary.Belt pulley drives flying wheel by the very little spring of a rigidity and rotates together, when torsional oscillation produces, produce relative angular displacement between belt pulley and the flying wheel, utilize angular lever angular displacement to be transformed into the rectilinear motion of push rod, pass through recording pointer again, vibration signal is recorded on the paper tape Here it is typical contact mechanical vibration tester with certain enlargement factor.Most representative is Gelger vialog and the Japanese imitation products that Germany makes, and they are all in a large amount of uses.What another kind of torsiograph adopted is the metering system of noncontact, promptly utilizes inductance type transducer, by measuring the phase shift of the gear (ingredient that belongs to sensor) that is contained on the turning axle non-contactly, obtains torsional vibration signals.For the contact vialog, its disadvantage is that the information (waveform) that records can't be analyzed, handle with electronic device, observes with the hand amount entirely, and it is slow and difficult to analyze speed, requires the tester that certain experience is arranged; For the contactless electronic vialog, remain the shortcoming that is restricted at test rotating speed lower limit, can not be used for, the vibration survey of low-speed diesel engine etc.
The objective of the invention is on the basis of existing Gelger formula vialog the output device of the electrical signal of the formula that designs a mechanism vialog.
The output device of the electrical signal of the mechanical type vialog that the present invention relates to has utilized the belt pulley ［ 1 ］ of existing machinery formula vialog, flying wheel ［ 2 ］, angular lever ［ 3 ］, push rod ［ 4 ］, bounce-back spring ［ 5 ］ and recording pointer ［ 6 ］, it is characterized in that on the basis that does not change existing machinery formula vialog structure, increased output device of the electrical signal, this device is by sheet metal ［ 7 ］ metalwork of other shapes (also), current vortex sensor ［ 8 ］ (also differential transformer type, capacitance type sensor etc.), sensor stand ［ 9 ］, transducer ［ 10 ］ and current vortex vialog ［ 11 ］ (match with corresponding sensor surveying instrument) are formed, can be with all kinds of electronic device records by the electric signal of the expression vibration strong or weak of output device of the electrical signal output, handle.The link position place that sheet metal ［ 7 ］ can be bonded in push rod ［ 4 ］ and recording pointer ［ 6 ］ also can cancel recording pointer ［ 6 ］, and a sheet metal ［ 7 ］ and an end of push rod ［ 4 ］ are directly bonded together.When bonding, should make the end face of sheet metal ［ 7 ］ keep vertical with the axis of push rod ［ 4 ］.In order to make push rod ［ 4 ］ in endoporus, keep rectilinear motion, can between the bearing endoporus of push rod ［ 4 ］ and bounce-back spring ［ 5 ］, add a guide piece.The height of sensor stand ［ 9 ］, front and back position, position, the left and right sides and the angle of pitch are all adjustable, and the manufacturing materials available metal of this support is also available nonmetal.
The output device of the electrical signal of mechanical type vialog provided by the invention can be when keeping electric signal output, keep tape recording to carry out synchronously, promptly do not destroy the function and the structure of former Gelger formula vialog, the advantage that has the contactless electronic vialog again, can be used for various in, the torsional vibration measurement of slow speed engine.
Fig. 1 is the structure principle chart of the output device of the electrical signal of mechanical type vialog.
Fig. 2 is the output device of the electrical signal schematic diagram of the mechanical type vialog behind the cancellation recording pointer.
Most preferred embodiment:
Link position place at push rod ［ 4 ］ Yu the recording pointer ［ 6 ］ of Gelger formula vialog shown in Figure 1, or at an end place of the push rod ［ 4 ］ of Gelger formula vialog shown in Figure 2, is that the flake aluminum ［ 7 ］ of 0.15mm is thereon bonding with epoxy glue with a thickness, and makes the axis of the end face of flake aluminum ［ 7 ］ and push rod ［ 4 ］ perpendicular as far as possible.When the range of the current vortex sensor of selecting for use ［ 8 ］ was 5mm, the diameter of flake aluminum ［ 7 ］ can be taken as 30mm.Current vortex sensor ［ 8 ］ is fixed on the sensor stand ［ 9 ］ of metal material making, height, front and back position, position, the left and right sides and the angle of pitch of sensor stand ［ 9 ］ are mixed up, the input end of transducer ［ 10 ］ is linked to each other with the stube cable of current vortex sensor ［ 8 ］, the input end of current vortex vialog ［ 11 ］ is linked to each other with the output terminal of transducer ［ 10 ］.At this moment, as Gelger formula vialog being connected on the tested turning axle (in, slow speed engine), the output device of the electrical signal of this mechanical type vialog is with regard to the corresponding electric signal waveform of exportable expression vibration strong or weak so.
