The utility model is characterized in that the device mainly comprises a support (1) with a circular experiment channel, a stator clamp ring (4) is also arranged in the circular experiment channel, and the stator clamp ring (4) is not a whole circle, but is provided with a gap; a rotating component (6) is fixed on a rotating shaft (2) at the inner side of the stator clamp ring (4), a clearance is arranged between the rotating component (6) and the stator clamp ring (4), and 2 to 4 rub-impact bolts (7) are arranged on the support (1) at the circular experiment channel part; when the rub-impact bolts (7) are tightened, the stator clamp ring (4) comes into contact with the rotating component (6). The device prevents the rotating shaft from being damaged, and simulates real rub-impact state.
Description
Technical field
Rotor rubbing test device of the present utility model relates to the annex on a kind of interchangeable rotor testing table, be a kind of rotor fault experimental simulation device, more particularly, the utility model is a simulation rotor rubbing malfunction test on the interchangeable rotor experiment table, and a kind of more true, more comprehensive experimental provision of function is provided.
Background technology
At present, laboratory rotor test platform commonly used is simulated the various running statuses of rotating machinery, but change quiet simulation of bumping fault is very big problem always, is not well solved for a long time.The existing device that rubs that bumps mainly is made up of the support that rubs screw and be fastened on the testing table, it mainly is to realize bumping the fault of rubbing by the distance of regulating bolt and rotating shaft, but, in bumping the experimentation that rubs, be to bump and rub based on bolt-rotor contact (i.e. contact), the situation of rubbing of bumping of this and most of actual rotor and stator misfits, only can simulate single-point and bump the phenomenon of rubbing, common multiple spot bumped rub, the part is bumped partially and complete cycle bumps and rubs, then powerless, and such bumping rubs and is easy to the damage axle, bumps the experiment that rubs and also can only carry out in the short time.So existing rotor experiment table rubbing test device is difficult to satisfy the teaching and scientific research requirement that the experiment that rubs is bumped in the laboratory.
The utility model content
Technical problem to be solved in the utility model is the deficiency that overcomes in the existing apparatus technology, propose a kind of can the quiet experimental provision that bumps the process of rubbing of simulates real real-turn.
A kind of rotor rubbing test device is characterized in that: mainly comprise the bearing that has circular experiment channel, the stator snap ring also is installed in the circular experiment channel, described stator snap ring is non-full circle week, and has the slit; Tumbler is fixed on and is positioned at stator snap ring inboard in the rotating shaft, and has the gap with the stator snap ring, is positioned at circular experiment channel place on the bearing and 2-4 also is installed bumps the bolt that rubs, and bumps when tightening that the stator snap ring contacts with tumbler when rubbing bolt.
Compared with prior art, the utility model has the advantages that:
1) specialized designs stator snap ring-bolt arrangement, both avoided rotating shaft to sustain damage, simulated the state of rubbing that truly bumps again, stator snap ring parcel tumbler is realized bumping rubbing;
2) tumbler and stator snap ring are changed easily, and can carry out processing and fabricating according to different materials, realize the multiple experimental study that rubs that bumps that bumps the rigidity of rubbing neatly;
3) this bumps the device that rubs and can be used with existing all interchangeable rotor experiment tablees, can install and test on the basis that does not influence current experiments platform structure and other experiments;
Description of drawings
Fig. 1 is that the utility model bumps the overall front view of the device that rubs.
Number in the figure title: 1-bearing; The 2-rotating shaft; 3-first platform; 4-stator snap ring; 5-second platform;
The 6-tumbler; 7-bumps mount screw; The 8-trip bolt
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Bump in the front view of the device that rubs at Fig. 1 the utility model, mainly comprise bearing (1), stator snap ring (4), tumbler (6), bump bolt that rubs (7) and fastening bolt (8) composition.This device is to be fixed on the experiment table by the fastening bolt (8) on the bearing (1), finishes experiment with miscellaneous part co-operate on the experiment table.
In this device, the mode with interference fit between tumbler (6) and the rotating shaft (2) is connected.It can be a disk, also can be other rotatable parts such as turbine or impeller, is very easy to change.
In addition, this bumps and has designed first platform 3 and second platform 5 that is mutually 90 degree on the device that rubs and be equipped with through hole, and the sensor of vibration displacement, speed and acceleration can be installed easily, obtains vibration displacement, speed and acceleration signal neatly.
Usually under the state, three are bumped the bolt that rubs and all become flexible, and tumbler runs well not interrupted.Do when needs and to bump when experiment of rubbing, turn three and bump the bolt that rubs and regulate gap between stator snap ring and the tumbler, thereby can realize easily that single-point, multiple spot, part and complete cycle bump the mode of rubbing.Slit because of stator snap ring lower limb makes the stator snap ring can close to some extent when the extruding that is subjected to bolt simultaneously, thereby can be good at the parcel tumbler, has both avoided rotating shaft to sustain damage, and has reached intimate complete cycle again and has bumped the effect of rubbing.Like this, the sensor that is installed on first platform 3 and second platform 5 just can pick up more directly and bump really the fault vibration signal that rubs, through the signal testing software of modulate circuit and data collecting card input PC, for experimenter's reading of data is studied or fault diagnosis provides and effectively bumps the data of rubbing.
Claims (2)
1. rotor rubbing test device is characterized in that: mainly comprise the bearing (1) that has circular experiment channel, stator snap ring (4) also is installed in the circular experiment channel, described stator snap ring (4) is non-full circle week, and has the slit; Tumbler (6) is fixed on and is positioned at stator snap ring (4) inboard in the rotating shaft (2), and there is the gap with stator snap ring (4), be positioned at circular experiment channel place on the bearing (1) and 2-4 also is installed bumps the bolt that rubs (7), stator snap ring (4) contacts with tumbler (6) when bumping the bolt that rubs (7) when tightening.
2. rotor rubbing test device according to claim 1 is characterized in that: described tumbler (6) is disk or turbine or impeller.
