Abstract
The utility model relates to a system for monitoring unbalanced loading of a planet gear of a wind generating set. A gearbox of the wind generating set comprises a sun gear, the planet gear and an inner gear ring. The monitoring system comprises an acceleration sensor installed on the inner gear ring and a signal acquisition and data processing system connected with the acceleration sensor. The system compensates for the defect that the unbalanced loading phenomenon in the operating process of a planet gear train of the wind powder gearbox and avoids the problem that because unbalanced loading of the planet gear cannot be restored in time, damage to the planet gear and a bearing is accelerated.
Description
Technical field
The utility model relates to wind power generating set component monitoring field, particularly relates to a kind of monitoring system of wind power generating set planetary pinion unbalance loading.
Background technique
Because Planetary Gear Transmission has the advantages such as compact structure, transmitted power density are large, the most of Planetary Gear Transmission that adopts of wind power generating set main-gear box at present, and most ofly adopt the type of belt drive that ring gear is fixed, retainer drives planet wheel rotation.But the machining accuracy of Planetary Gear Transmission to planetary gear train, installation precision is had relatively high expectations, in actual application process because various trueness errors and distortion tend to cause planetary gear train to have load skewness phenomenon, i.e. unbalance loading phenomenon.Unbalance loading is in certain scope, little on the life-span impact of gear-box, but in the time that unbalance loading is excessive, will cause certain planet wheel overload, and load exceedes design load capacity, planetary pinion or bearing generation earlier period damage.
If main-gear box is damaged, especially planetary pinion breaks down, must transport gear-box back factory from cabin lifting to ground and repair, and somewhat expensive, the cycle is long, has a strong impact on unit generation amount.For early monitoring gearbox fault, industry generally adopts system of condition monitoring to carry out Real-Time Monitoring to gear-box operation conditions at present, but the at present this monitoring method by analysis rumble spectrum and passband vibration values can not be identified the instantaneous mesh impact of planet wheel through acceleration transducer, thereby cannot judge the unbalance loading fault of planetary stage gear.
How to found and a kind ofly monitor planetary pinion unbalance loading fault so that the monitoring system of the new wind power generating set planetary pinion unbalance loading of in time planet wheel being safeguarded, real one of the current important research and development problem that belongs to.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of monitoring system of wind power generating set planetary pinion unbalance loading, make it can monitor in time, accurately planetary load condition, avoid unbalance loading fault in time planet wheel is safeguarded, thereby overcome the deficiency that existing wind power generating set planetary pinion unbalance loading cannot detect, maintenance expenses is high.
For solving the problems of the technologies described above, the utility model provides a kind of monitoring system of wind power generating set planetary pinion unbalance loading, the gear-box of described generator set comprises sun gear, planet wheel and ring gear, and described monitoring system comprises the upper acceleration transducer and connected signals collecting and the data processing system that are arranged on ring gear.
As a kind of improvement of the present utility model, described signals collecting and data processing system are also connected with client end display system.
Described client end display system is connected with signals collecting and data processing system communication.
Also comprise the speed probe that is arranged on ring gear inner side.
Described signals collecting and data processing system are mainly made up of PLC and data collecting card.
Adopt after such design, the utility model at least has the following advantages:
1, the utility model discloses a kind of wind power generating set main-gear box planetary pinion unbalance loading fault monitoring system, having made up in industry is the blank of the monitoring equipment of unbalance loading phenomenon in running to planetary wheel of wind turbine gearbox at present.
2, realized the operating load condition of main-gear box planetary stage has been carried out to Real-Time Monitoring by this model utility, avoid planetary pinion exist unbalance loading to repair not in time and accelerate the problem of the damage of planetary stage gear and bearing, save maintenance cost, improved unit working efficiency.
Accompanying drawing explanation
Above-mentioned is only the general introduction of technical solutions of the utility model, and in order to better understand technological means of the present utility model, below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
Fig. 1 is the structural representation of the monitoring system of a kind of wind power generating set planetary pinion of the utility model unbalance loading.
Embodiment
Shown in Fig. 1, the utility model provides a kind of monitoring system of wind power generating set planetary pinion unbalance loading, described unit comprises sun gear 4, planet wheel 1 and ring gear 5, and this monitoring system comprises the upper acceleration transducer 7 and connected signals collecting and the data processing system that are arranged on ring gear 5.
Preferably, the inner side of ring gear 5 also can be provided with the speed probe 8 of the absolute parallax angle signal that can gather planet carrier 6, and signals collecting and data processing system are also connected with client end display system.
Signals collecting and data processing system mainly contain PLC and data collecting card composition, by the signal of speed probe 8, judge the engaging position of planet wheel 1 and ring gear 5, thereby the oscillating signal while accurately intercepting the ring gear below planet wheel 1 process vibration transducer, the oscillating signal intercepting is processed, calculate as required the vibration engagement capacity volume variance of mesh vibration energy, each planet wheel, thereby judge the unbalance loading degree of planetary gear train.
Client end display system is connected with signals collecting and data processing system communication, the information that the primary signal of degree of will speed up sensor, speed probe collection and signals collecting and data processing system processing obtain shows, so that O&M personnel can find out planetary unbalance loading degree intuitively.
The utility model is further explained as example to contain three planet wheels 1, ring gear 5 and planet carrier 6 is fixing, sun gear 4 rotates planetary pinion below.
The absolute encoder image data signal that described speed probe 8 also can use wind power generating set to carry.
The above; it is only preferred embodiment of the present utility model; not the utility model is done to any pro forma restriction, those skilled in the art utilize the technology contents of above-mentioned announcement to make a little simple modification, equivalent variations or modification, all drop in protection domain of the present utility model.
