Detailed Description
The embodiment of the invention provides a method and a device for detecting and processing the slippage of a torque-limiting damper, and solves the technical problem of how to detect the slippage of the torque-limiting damper.
In order to better understand the technical scheme of the invention, the technical scheme of the invention is described in detail in the following with the accompanying drawings and specific embodiments.
First, it is stated that the term "and/or" appearing herein is merely one type of associative relationship that describes an associated object, meaning that three types of relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter associated objects are in an "or" relationship.
As shown in fig. 1, the method for detecting and processing the slip of the torque limiter damper of the present embodiment includes:
the method comprises the following steps that S1, the rotating speed of an engine and the rotating speed of an input shaft of a target mechanism are obtained, and torque is transmitted between the engine and the target mechanism through a torque limiting shock absorber;
and S2, if the rotation speed difference between the rotation speed of the engine and the rotation speed of the input shaft is higher than a preset rotation speed difference threshold value, determining that the torque-limiting shock absorber slips.
Experiments show that when the torque-limiting shock absorber does not slip, the flywheel is in hard connection with the target mechanism, and the rotating speed of the engine is the same as that of the input shaft of the target mechanism; when the torque-limiting damper slips, the engine speed and the input shaft speed of the target mechanism are different. Thus, when it is detected that the engine speed and the input shaft speed of the target mechanism are different, it is possible to determine that the torque limiter damper slips. However, considering the influence of the accuracy of the sensor for detecting the rotational speed, the detected rotational speed is not necessarily the actual rotational speed of the engine or the input shaft, for example, the actual rotational speed of the engine is 1000, and the actual rotational speed of the input shaft of the target mechanism is 1000, but the engine rotational speed detected by the sensor may be 1010 and the input shaft rotational speed 990, and although the detected engine rotational speed is different from the input shaft rotational speed, it can be considered that the torque limiter damper does not slip.
As can be seen from the above, the method for detecting and processing the slip of the torque limit damper in this embodiment obtains the rotation speed of the engine and the rotation speed of the input shaft of the target mechanism, determines that the torque limit damper slips if the rotation speed difference between the rotation speed of the engine and the rotation speed of the input shaft is higher than the preset rotation speed difference threshold, and can determine whether the torque limit damper slips by determining whether the rotation speed of the engine and the rotation speed of the input shaft are close to the same.
In step S1, the target mechanism may be a generator or a gearbox. In step S2, the preset rotation speed difference threshold may have a value range of 30 to 50 rpm.
After the slipping of the torque-limiting damper is determined, the cause of the slipping of the torque-limiting damper needs to be further judged so as to purposefully eliminate the slipping phenomenon of the torque-limiting damper. For this reason, after the step S2, the method for detecting and processing the slip of the torque limiter damper further includes:
acquiring the torque of the engine and the slip torque of the torque-limiting shock absorber; and determining the slip reason of the torque limiting damper according to the engine torque and the slip moment. In this embodiment, the causes of the slip of the torque limiter damper include a failure of the torque limiter damper and a failure of the engine, and the failure of the engine includes a misfire failure and other failures of the engine.
Generally, the torque limiting function of the torque limiting shock absorber can play an overload protection role on a torque transmission path, which is embodied in that when the torque limiting shock absorber has no fault, if the torque of an engine is higher than the slipping torque of the torque limiting shock absorber, the torque limiting shock absorber can eliminate the overlarge torque of the engine through slipping, so that the torque of the engine is prevented from being transmitted to a target mechanism, and the slipping under the condition is the normal action of the torque limiting shock absorber; when the engine torque is lower than the slip torque of the torque limiting damper, the torque limiting damper will transmit the engine torque to the target mechanism. Based on this, the cause of the slip of the torque limiter damper can be determined by the magnitude relationship between the engine torque and the slip torque of the torque limiter damper.
Specifically, determining the cause of the slip of the torque limiter damper according to the engine torque and the slip torque may include:
if the torque of the engine is lower than the slipping torque, determining that the slipping reason of the torque limiting damper is the failure of the torque limiting damper;
and if the engine torque is higher than the slip torque, determining the reason for the slip of the torque limiting damper as the engine fault.
If the engine torque is lower than the slip torque, which means that the torque-limiting damper does not slip due to the excessively large engine torque, the reason for the slip of the torque-limiting damper can only be the failure of the parts of the torque-limiting damper.
Considering that in extreme cases, the torque limiter damper fault and the engine fault may occur simultaneously, if the engine torque is higher than the slip torque, the reason only representing the slip of the torque limiter damper includes the engine fault, and it cannot be determined whether the engine fault is the only reason. In order to accurately determine the cause of the slip of the torque limiter damper when the engine torque is higher than the slip torque, the present embodiment preferably determines the cause of the slip of the torque limiter damper according to the engine torque and the slip torque, and includes:
if the torque of the engine is lower than the slip torque, determining that the reason for the slip of the torque limiting damper is the fault of the torque limiting damper;
if the engine torque is higher than the slip torque, reducing the engine torque to be lower than the slip torque, and acquiring the engine rotating speed and the input shaft rotating speed again; if the rotating speed difference between the rotating speed of the engine and the rotating speed of the input shaft is higher than a preset rotating speed difference threshold value, determining the reason for the slippage of the torque limiting shock absorber as a fault of the torque limiting shock absorber and a fault of the engine; and if the rotating speed difference between the rotating speed of the engine and the rotating speed of the input shaft is lower than a preset rotating speed difference threshold value, determining that the reason for the slipping of the torque limiting shock absorber is the engine fault.
After the engine torque is higher than the slip torque, the engine torque can be reduced to be lower than the slip torque, so that if the torque-limiting shock absorber has no fault, the rotation speed difference between the rotation speed of the engine and the rotation speed of the input shaft acquired again is lower than a preset rotation speed difference threshold value; if the torque limiting damper fails, the rotational speed difference between the engine rotational speed and the input shaft rotational speed, which is again obtained, should be higher than the preset rotational speed difference threshold. On the contrary, if the rotation speed difference between the rotation speed of the engine and the rotation speed of the input shaft acquired again is lower than the preset rotation speed difference threshold value, the reason representing the slipping of the torque limiting shock absorber only comprises the engine fault; if the rotation speed difference between the engine rotation speed and the input shaft rotation speed acquired again is still higher than the preset rotation speed difference threshold value, the reason representing the slipping of the torque limiting damper also comprises a fault of the torque limiting damper.
In the embodiment, after the reason that the torsion-limiting damper slips is determined to comprise the fault of the torsion-limiting damper, the torsion-limiting damper needs to be replaced; after determining that the cause of the slip of the torque limiter damper includes the engine failure, it may be further determined whether the cause of the engine failure is the engine misfire or other causes, and specifically, whether the engine misfire may be detected by a sensor.
In this embodiment, if the cause of the slip of the torque limit damper is an engine fault, it indicates that the engine torque is too high, and the torque limit damper can slip all the time due to the always too high engine torque, so that the friction plate of the torque limit damper is ablated, and the torque limit damper is damaged. In order to prevent the torque limiting damper from being damaged due to the fact that the engine torque is always too high, preferably, after the reason for the slip of the torque limiting damper is determined according to the engine torque and the slip torque, the method for detecting and processing the slip of the torque limiting damper further comprises the following steps:
and if the reason for the slippage of the torque limiting damper is engine failure, the engine torque is reduced to be lower than the slippage torque.
