Embodiment
Referring to Fig. 1, multi-fault coupling gear box simulated experiment bench of the present invention comprises: a base 6, and base 6 is provided with motor 1, this motor 1 is connected with multiple faults coupling wheel case 3 by first shaft coupling 2, and multiple faults coupling wheel case 3 links to each other with generator 5 by second shaft coupling 4.
Described multiple faults coupling wheel case 3 is provided with oil ga(u)ge 22.Be provided with input splined shaft 21 and output spline 14 in the multiple faults coupling wheel case 3, between input splined shaft 21 and the output spline 14 transition axis 12 arranged, input splined shaft 21, output spline 14 and 12 3 axles of transition axis are not at grade; On the input splined shaft 21 first spline gear 7 is installed, second spline gear 16 is installed on the output spline 14, the dual gear and a triple gear of two gears (9,10) formation is installed on the transition axis 12 or connects gear 18 more, first spline gear 7 and dual gear engagement, second spline gear 16 is with triple gear or connect gear 18 engagements more, at first spline gear 7 and second spline gear, 16 next doors the first shift fork transposer 23 and the second shift fork transposer 15 is arranged respectively also.Be in operation and stir dual gear or triple gear or connect gear more by first, second shift fork transposer, can the multiple gear distress of continuous analog.
Typical simulation project is:
1. Gear Root fatigue crack and broken teeth simulation test;
2. gear spot corrosion and peel off simulation test;
3. gear teeth face wearing and tearing simulation test;
4. the eccentric simulation test of gear.
Be in operation by the shift fork transposer and can observe gear easily: be normal → tooth root fatigue crack → broken teeth; Normally → and spot corrosion → peel off; Normally → tooth surface abrasion; Normally → signal change procedure of faults such as off-centre.Multi-fault coupling gear box simulated experiment bench can also be provided with speed governing load test system and monitoring system, and this speed governing load test system is made up of direct current motor, timing control cabinet, Dyn., field regulator and resistance box commonly used.Monitoring system is made up of vibration acceleration sensor, charge amplifier, data collecting card, computing machine, output device.
