Embodiment
Core of the present invention is to provide a kind of measurement mechanism of floating-ring bearing rotating ratio, and the measurement of rotating speed research for floating-ring bearing provides tests support reliably.。
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Referring to figs. 1 to Fig. 5, a kind of measurement mechanism of floating-ring bearing rotating ratio, comprising: drive motor 1; The variator 3 that input shaft is connected with drive motor 1 output shaft; The test axle 13 that incoming end is connected with variator 3 output shaft; Be set in the floating ring 8 of test axle 13 test lead; Be set in two loop component of test axle 13 test lead, two loop component are distributed in the two ends of floating ring 8; Package testing axle 13 test lead, coordinates with two loop component the lining 9 forming confined space; The bearing 12 of support bushing 9, bearing 12 is provided with hollow hole, lining 9 and hollow hole interference fit; Lubricating oil is provided with in confined space; Be arranged on the even number of permanent magnets sheet 82 on floating ring 8; Be arranged on lining 9, be in the concave station 92 in same transversal section with permanent magnet piece 82; Be arranged on the speed probe in concave station 92; Receive speed probe 19 data, and carry out the Signal reception disposal system of data processes and displays.
The principle of work of this measurement mechanism is: first drive motor 1 outputting power, and rotating speed, the moment of torsion of drive motor 1 pass to test axle 13 by variator 3, and variator 3 serves the effect of speedup in the process.In test lead floating ring 8 and test axle 13 and floating ring 8 clearance fit of test axle left end, and floating ring 8 and lining 9 are also clearance fit, floating ring 8 and test axle 13 between and be all full of lubricating oil between floating ring 8 and lining 9, when testing axle 13 and rotating under the driving of drive motor 1, form lubrication wedge inside test axle 13 and floating ring 8, the oil film wedge oil-film force effect that rotates through of test axle 13 drives floating ring 8 with certain rotational speed.Lining 9 is arranged on bearing 12 by interference fit, ensure that the stability of test axle 13 lining 9 in high-speed rotation process.Above process completes the work simulation to floating-ring bearing.
The permanent magnet piece that floating ring 8 is arranged, the speed probe 19 that correspondence is arranged on lining is responded to permanent magnet piece, and the data of record are sent to Signal reception disposal system.Experimental data carries out processing and showing by this Signal reception disposal system, and above process completes data processing display.
In order to optimize technique scheme further, the present embodiment adds weight load 5 on test axle 13, because need simulating actual conditions, and have the situation of loading ability of bearing different loads, therefore can, by regulating the magnitude of load of weight load 5, realize testing different bearing load parameter to the impact of this device to test.
In order to optimize technique scheme further, the present embodiment is provided with oil-through hole 81 on floating ring 8, like this initial this proving installation is installed time just without the need at floating ring 8 and test between axle 13 and add lubricating oil, but directly lubricating oil is added in the confined space between test axle 13 and lining 9, when testing axle 13 and driving floating ring 8 to rotate, lubricating oil just can enter floating ring 8 with in test axle 13 in oil-through hole 81, thus has better lubricant effect.
As shown in Figure 4, further optimize technique scheme, on lining 9, top is provided with oil hole 91, and on bearing 12 top, through bearing 12 and oil hole 91, the oiling plug screw 7 of straight-through confined space.Can oiling or change the lubricating oil of different model by refueling plug screw 7 pairs of confined spaces, when just noting be used in oil change, dismounting process is carried out to exchange lubricating oil for lining 9.
Further optimize technique scheme as shown in Figure 6, the first end cap 6 and the second end cap 11, first end cap 6 that arrange bearing 12 hollow hole two ends also drawn together by this proving installation and the second end cap 11 is fastened on bearing 12 by bolt 10.This structure ensure that the intensity of lining 9 in hollow hole, the stability of lining 9 when also ensure that test axle 13 rotates.
Further optimize technique scheme, drive motor 1 output shaft is connected by the first shaft coupling 2 with transmission input shaft 18; The output shaft of variator 3 is connected by the second shaft coupling 4 with test axle 13.Because the two piece axles (main drive shaft and driven shaft) of shaft coupling in connection different institutions make it jointly to rotate with the extraordinary selection of transmitting torque.Especially at a high speed and in the larger power transmission of weight load 5, shaft coupling also have cushion, the effect of vibration damping and raising axle system dynamic property, therefore select shaft coupling to connect between axle.
Further optimize technique scheme, the quantity of permanent magnet piece is 2, is symmetrically distributed on the same transversal section of floating ring 8.On.Symmetrical install balance when can ensure that floating ring 8 rotates and stability, floating ring 8 speed probe that often turns around can obtain two voltage signals.Permanent magnet piece 82 quantity is more, and signals of rotational speed sensor frequency is larger, namely can receive the induction of signal of permanent magnet piece 82 better.
Further optimize technique scheme, drive motor 1 is permanent-magnet brushless AC motor, and running parameter is: operating voltage 220V, working current 15A, power 2000W, maximum functional rotating speed 8000r/min, to guarantee to reach the simulation of floating ring under various duty.Compared with traditional electric exciting motor, permanent magnet motor structures is simple, reliable, volume is little, quality is little, loss is few, efficiency is high.
Further optimize technique scheme, gearbox 3 is planetary gear construction, is made up of gear ring 14, planet carrier 16, sun gear 15 and planet wheel 17, and ratio of gear is 2,6,12,18,24,36 amount to 6 gears.Multi-change speed can be realized thus warranty test platform works in the larger range of speeds.
As shown in Figure 7, further optimize technique scheme, the course of work of Signal reception disposal system is as follows: signal amplifier receives the data of speed probe 19 and to go forward side by side row relax; The data of A/D converter receiving signal amplifier transmission are gone forward side by side row relax; Microprocessor receives the data of A/D converter and to go forward side by side row relax; The result of calculation receiving microprocessor shows by display.
First, second described herein word such as grade, only in order to the different parts that specification configuration is identical or similar, does not represent the restriction to certain particular order.
Above the measurement mechanism of floating-ring bearing rotating ratio provided by the present invention is described in detail.Apply specific case herein to set forth principle of the present invention and embodiment, the explanation of above embodiment just understands core concept of the present invention for helping.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improve and modify and also fall in the protection domain of the claims in the present invention.
