In order to realize the above-mentioned purpose, the utility model provides a self-aligning ball bearing swing endurance test frock, the on-line screen storage device comprises a base, the base on be provided with swing subassembly and detection axle, swing subassembly including driving medium, connecting piece, the driving medium swing that can reciprocate to stretch out and draw back, connecting piece one end fixed mutually with the driving medium, the other end of connecting piece is provided with the installation cover that supplies the bearing inner race to cup joint, the installation ways establish and be formed with the detection station that can supply the bearing installation that awaits measuring on the detection axle and with it.
The technical scheme has the advantages that: the one end through driving medium and connecting piece is fixed, and the setting of the reciprocal flexible wobbling of driving medium, and the installation cover of connecting piece other end department with detect and form the detection station between the axle, the bearing that will await measuring is installed in detecting the station, the inner circle of bearing cup joints and is detecting epaxially, the connecting piece drives the outer lane reciprocating motion of the bearing that awaits measuring under the drive of driving medium, can measure the data of bearing swing wearing and tearing, and because the reciprocal flexible swing of driving medium, make one end and its fixed driving medium not simple sideslip, but produce the slope at the in-process of sideslip, the swing, simulation operating condition that can be fine.
The utility model discloses can further set up to: the swing assembly further comprises a first motor and an eccentric wheel, the eccentric wheel is sleeved on an output shaft of the first motor, a rotation connection point is formed between the eccentric wheel and the transmission piece, and the rotation connection point moves circumferentially by taking the output shaft of the first motor as a circle center.
Through further setting up, form between eccentric wheel and the driving medium of setting between first motor output shaft and driving medium and rotate the tie point to rotate the tie point and carry out the motion of circumference, thereby make the driving medium longitudinal oscillation when transversely flexible, thereby form the swing of stretching out and drawing back repeatedly of driving medium.
The utility model discloses can further set up to: the base is provided with a support frame, the detection shaft is arranged on the support frame in a penetrating mode, the support frame is provided with a guide plate, a long groove for the connecting piece to penetrate is formed in the guide plate, and the long groove extends along the extension direction of the transmission piece.
Through further arrangement, an elongated slot for the connecting piece to penetrate is formed in the support frame guide plate and extends along the telescopic direction of the transmission piece, so that the connecting piece part penetrating in the elongated slot can slide along the inner wall of the elongated slot in a guiding mode, the connecting piece is prevented from moving towards other directions in the operation process of the tool, other interference items of the test are reduced, and the operation stability of the test tool is ensured.
The utility model discloses can further set up to: and the detection shaft is provided with a second motor for driving the detection shaft to rotate.
Through further setting, the second motor drives the detection shaft to rotate, and under the better simulation operating mode, the running condition of bearing.
