Abstract
The utility model discloses a bearing flexibility detection disk. A coupling shaft (2) is arranged on one side of a rotary disk (1); one end of the coupling shaft (2) is fixedly connected to the middle of the rotary disk (1); a mandrel (3) is arranged at the other end of the coupling shaft (2); the diameter of the mandrel (3) is smaller than that of the coupling shaft (2); and the axes of the mandrel (3), the coupling shaft (2) and the rotary disk (1) are positioned on the same straight line. A mechanical tool and manual rotary handfeel are adopted, so that the bearing flexibility and the vibration shortcoming caused by high-speed running can be identified, and the shortcomings which cannot be found during low-speed running can be identified; and the bearing flexibility detection disk has the characteristics of simple structure, low cost and the like and is convenient and easy to learn.
Description
Technical field
The utility model relates to a kind of bearing dirigibility detection dish, is used to detect the dirigibility and the running quality of bearing.
Background technology
At present, the detection mode of bearing dirigibility has traditional-handwork to detect and detects two kinds through the special vibrating measuring instrument.It is directly to rotate the outer ring with staff that traditional-handwork detects; Hold the inner ring end face simultaneously and feel its flexibility of revolution; Riveted defectives such as main identification bearing clamping stagnation, folder ball, but the vibration defective that exposes can't discern bearing operation the time, as: raceway dregs, raceway defective etc.
Bearing special vibrating measuring instrument S0910 is to drive the inner ring high speed rotating at mandrel, the outer ring is applied under the situation that axial load limits its rotation, carries out spot measurement through sensing system.The acceleration sensor system is in 50Hz～10000 Hz frequency ranges; Following feature is good; Though can the concrete numerical value of measuring vibrations, the identification bearing vibration defective that runs up and expose; But can't accurately discern the vibration defective that the bearing low-speed running exposes, as: tiny dregs in the raceway, raceway tinyly damage, the tiny ultra smart defective of raceway etc.In addition,,, have only, when transducer probe assembly is in this point defect position, could discern its defective, can influence the efficient of measurement like this, and have omission hidden danger through multimetering repeatedly for the single-point defective in the bearing channel because sensor is spot measurement.
The utility model content
The utility model technical matters to be solved is to provide a kind of detection dish that can discern the vibration defective of bearing flexibility of revolution and the exposure of high low-speed running.
The technical scheme of the utility model is following: a kind of bearing dirigibility detection dish; Side at rotating disc is provided with coupling spindle; One end of this coupling spindle and the middle part of rotating disc are fixedly linked; The other end at coupling spindle is provided with mandrel, and the diameter of this mandrel is less than the diameter of coupling spindle, and mandrel, coupling spindle and rotating disc three's axial line point-blank.
Adopt above technical scheme; Hand-tight whole cylindrical of measured bearing (applying radial force) of holding of testing staff; The another hand coils mandrel with detection and inserts the measured bearing endoporus; Rotate rotating disc (can arbitrarily adjust its rotating speed) then, bearing inner assembly drives low-speed running under the load of detection dish weight by mandrel, receives the bearing operation quality through the feel of holding bearing top circle.
Bearing turns round under aforesaid way, the elastic deformation of bearing parts and except that the necessary motion of bearing function other all depart from the motion of ideal position, all come out through the outer ring.Hold the hand of bearing top circle and not only can obviously discern the bearing flexibility of revolution and the vibration defective of the exposure that runs up; As: clamping stagnation, folder ball, raceway groove dregs, raceway groove damage, the ultra smart defective of raceway groove etc.; And can discern the vibration defective that the bearing low-speed running exposes, as: tiny dregs in the raceway, raceway tinyly damage, the tiny ultra smart defective of raceway etc.The single-point of raceway is damaged, and one time wheel measuring can be discerned, and does not need repeated multiple times to measure.
For simplified structure, make things convenient for processing and manufacturing, said mandrel, coupling spindle and rotating disc are the integrative-structure of machine work moulding.
As preferably, there is the oblique angle end at said mandrel two ends.
As preferably, there is the oblique angle outer at said rotating disc two ends.
Beneficial effect: the utility model adopts mechanical frock, artificial rotation feel; The vibration defective that not only can discern the bearing dirigibility and run up and expose; Also can discern the defective that low-speed running can't expose simultaneously, have simple in structure, with low cost, make things convenient for characteristics such as Yi Xue.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the user mode figure of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
As shown in Figure 1, the utility model is made up of rotating disc 1, coupling spindle 2 and mandrel 3, and said mandrel 3, coupling spindle 2 and rotating disc 1 are the integrative-structure of machine work moulding, and three's axial line point-blank.One end of said coupling spindle 2 links to each other with the middle part of rotating disc 1, and there is the oblique angle outer at these rotating disc 1 two ends, and the other end of coupling spindle 2 links to each other with mandrel 3, and the diameter of this mandrel 3 is less than the diameter of coupling spindle 2, and there is the oblique angle end at mandrel 3 two ends.
Among Fig. 1, the hardness of mandrel 3 is 60HRC-65HRC, and mandrel 3 length h are greater than measured bearing height 2mm～4mm, and mandrel 3 diameter d cooperate with the measured bearing endoporus, and its limit deviation is seen table 1.
Table 1
Measuring load is provided by detection dish weight, and detection dish weight can be adjusted through rotating disc thickness h 1 according to the measured bearing size, usually thickness h 1 value 7mm～11mm.
For guaranteeing the steady of load, rotating disc 1 should not surpass 0.2mm with the right alignment of mandrel 3.
The verticality of coupling spindle 2 end faces and mandrel 3 should not surpass 0.006mm.
Detection dish height overall h2 and rotating disc diameter d 2 are chosen according to the suitability of staff.Recommend h2=45mm, d2=110mm.
As shown in Figure 2; During detection; Hand of testing staff applies radial force along direction F, holds on measured bearing 4 whole cylindricals, and the another hand rotates rotating disc 1 (can arbitrarily adjust its rotating speed); Bearing 4 inner assemblies low-speed running under the load of detection dish weight receives the bearing operation quality through the feel of holding bearing top circle.
