Abstract
The invention discloses a method for testing the durability of a starter. The method for testing the durability of the starter includes the steps that the starter is connected to an analog power source, and the terminal voltage of the starter in a power-on state is higher than a rated voltage; the starter conducts circulation at preset frequency, wherein the circulation includes that the starter is started at the first preset time when an ignition circuit of the starter is open and an accelerator of a diesel engine is turned off, the starter is started at the second preset time when the ignition circuit of the starter is closed and the accelerator of the diesel engine is turned on, the starter is started at the third preset time when the ignition circuit of the starter is open and the accelerator of the diesel engine is turned off, and the starter is shut down at the fourth preset time. Through the method, the circulation frequency of the starter is greatly reduced, the cost is lowered, and the test efficiency is improved; different preset circulation frequencies are adopted for a direct-driven starter and a speed change starter respectively, and adverse effects caused by too many times of circulation of the speed change starter are avoided.

Technical field
The present invention relates to engine art, particularly a kind of durability test method of starter.
Background technology
The endurancing scheme of JB-T_6707-2006 motor vehicle and starter for internal combustion engine comprises following two kinds:
1, starter is contained on the engine of adapted, under normal conditions, complete predetermined start cycles number of times by the actual loading of normal starter, according to the different purposes of starter, predetermined start cycles number of times is 10000～40000 times, when test, starter skin temperature is no more than 50 DEG C, allows to adopt fan blower cooling.
2, starter is contained on the engine or simulator stand of adapted, load is the load current maximal value that load performance that product technology condition specifies specifies, starter completes predetermined start cycles number of times, according to the different purposes of starter, predetermined start cycles number of times is 5000～30000 times, when test, starter skin temperature is no more than 50 DEG C, allows to adopt fan blower cooling.
Wherein each startup circulation continuous 40s, is successively starter energising 5s (comprise dead startups 4s, startup 1s lives), the anti-2s that drags of motor, and starter cool time is 33s.
The bulk testing overlong time of above-mentioned two kinds of test methods, and continue, in low-speed running filling, to cause the insufficient lubrication of the lubricating system of diesel engine, causing the wearing and tearing of diesel engine kinematic pair, damage, cost is too high.And, while requiring test, starter skin temperature is no more than 50 DEG C, although allow to adopt fan blower cooling, but be difficult to reach said temperature requirement, actual test conditions can reach 120 DEG C of left and right, and user's practical service environment is so not desirable, and therefore skin temperature cannot reach above-mentioned requirements substantially, and this just makes test cannot embody the real quality level of starter.
In addition, only for direct-driving type starter, (main driving rotor speed is low for existing test method, torsion is large), and speed change starter replaces gradually direct-driving type starter (main driving rotor speed is high in recent years, torsion is little), compare direct-driving type starter, the heat producing when the test of speed change starter is higher, the easier high temperature deformation of motor, more easily wearing and tearing and locking, but still use the test method of direct-driving type starter to test speed change starter, and make speed change starter complete same test number (TN), cannot reach the object of test.
The information that is disclosed in this background technology part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply that in any form this information structure has been the known prior art of persons skilled in the art.
