Description
Technical field
The utility model relates to fatigue tester technical field, the eccentric pinch roller of specially a kind of switch fatigue test machine.
Background technique
For eccentric wheel when machine power field is often mounted in and rotates on axis, the outer rim of wheel pushes another parts, generates reciprocal fortune
It is dynamic.But just with eccentric wheel rotation forces object, do not stop to rub between each other, abrasion is extremely serious, while can generate very big
Noise.
Utility model content
The utility model aim aims to solve the problem that problems of the prior art, and providing one kind can prevent from wearing, and reduces
The eccentric pinch roller of the switch fatigue test machine of noise.
To realize the above-mentioned technical purpose, the application adopts the following technical scheme that
A kind of switch fatigue test machine eccentric pinch roller, including eccentric wheel ontology, the eccentric wheel ontology are equipped with one partially
Arbor hole is set with a rotation axis in eccentric pivot hole, and the eccentric wheel ontology fixed sleeves are equipped with buffering bearing, the eccentric wheel
Ontology excircle and the bearing inner race circumference secure bond.
A kind of eccentric pinch roller of switch fatigue test machine as described above, the bearing top circle week is cased with cushion collar, described
Cushion collar is rubber sleeve or silica gel sheath.
A kind of eccentric pinch roller of switch fatigue test machine as described above, the eccentric wheel ontology have multiple, multiple bias
Ontology is taken turns to be arranged side by side.
A kind of eccentric pinch roller of switch fatigue test machine as described above, the rotation axis, which is equipped with, can drive another rotation axis
The synchronous pulley of Synchronous Transmission.
A kind of eccentric pinch roller of switch fatigue test machine as described above, the rotation axis both ends are set with bearing, bearing
It is fixedly mounted on bearing block, is fixedly connected with the drive pulley for cooperating with motor in the rotation axis, on drive pulley
Equipped with magnet, the Hall element being on magnet rotational trajectory is correspondingly provided on the bearing block.
The utility model has the beneficial effects that
1, rotary power is become Vertical Dynamic equipped with buffering bearing by eccentric wheel ontology fixed sleeves, and eccentric wheel ontology is turned
The potential difference up and down generated when dynamic becomes that object is vertically pushed to move up and down using bearing, it is therefore prevented that eccentric wheel ontology directly contacts quilt
Object is pushed, the abrasion of both sides is caused, also avoids generating noise.
2, using multiple eccentric wheel ontologies, bearing can be made and pushed away that object contact area is bigger, and stability is strong.
3, rubber or silica gel cushion collar are cased with bearing top circle week, increases buffer strength, reduces abrasion and noise.
4, rotation axis has the synchronous pulley that can drive another rotation axis Synchronous Transmission, realizes that a motor can drive multiple groups
Testing fatigue component works at the same time, energy-efficient.
5, drive pulley is equipped with magnet, and bearing block is equipped with Hall element, and when drive pulley rotation, Hall element is logical
The magnetic induction to magnet on drive pulley is crossed, the magnetic signal sensed is converted into electric signal and is conveyed at control unit
Reason and counting, the convenient number of revolutions programming count to drive pulley.

Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8 and Fig. 9, a kind of eccentric pressure of switch fatigue test machine
Wheel, including eccentric wheel ontology 1, eccentric wheel ontology 1 are equipped with an eccentric pivot hole 2, are set with a rotation axis 4 in eccentric pivot hole 2, partially
1 fixed sleeves of heart wheel ontology are equipped with buffering bearing 3,1 excircle of eccentric wheel ontology and 3 inner ring circumference secure bond of bearing.
It is further improved, 3 excircle of bearing is cased with cushion collar 5, and cushion collar 5 is rubber sleeve or silica gel sheath.
To make bearing and being pushed away that object contact area is bigger, and stability is strong, in the application, eccentric wheel ontology 1 have it is multiple, it is more
A eccentric wheel ontology 1 is arranged side by side.
It is further improved, rotation axis 4 is equipped with the synchronous pulley 6 that can drive another 4 Synchronous Transmission of rotation axis, two-by-two synchronous belt
It is driven by transmission belt 15, it can be achieved that a motor drives multiple testing fatigue components to work at the same time between wheel 6.
It is further improved, 4 both ends of rotation axis are set with bearing, and bearing is fixedly mounted on bearing block 7, solid in rotation axis 4
Surely it is connected with the drive pulley 9 for cooperating with stepper motor, drive pulley 9 is equipped with magnet 14, is correspondingly provided on bearing block 7
The Hall element being on 14 rotational trajectory of magnet, when 9 rotary magnet 14 of drive pulley is close to Hall element, Hall element is connect
The induced signal of the magnet 14 on drive pulley 9 is received, and the magnetic signal sensed is converted into electric signal and is conveyed to control
Unit is handled and is counted, and the convenient velocity of rotation to stepper motor detects, convenient to stepper motor rotation speed regulating and controlling.
