Description

Device and method for detecting meshing of internal gear of starter Technical Field The invention belongs to the field of starter internal gear detection, and particularly relates to a starter internal gear meshing detection device and a detection method. Background The automobile starter is a core component for converting electric energy into mechanical energy and driving an engine crankshaft to rotate so as to realize starting, is designed around 'short-time high-power output, reliable engagement and engine working condition adaptation', is widely applied to various automobile power systems such as passenger cars, commercial vehicles and the like, utilizes direct-current electric energy provided by a storage battery to drive a motor rotor to rotate at a high speed, converts the electric energy into the mechanical energy, and controls a driving gear to be accurately engaged with an engine flywheel gear ring through an electromagnetic switch or a mechanical shifting fork so as to transmit the torque of the motor to the engine crankshaft, so that the reliability and stability of a starting process are directly determined by the engagement performance of an internal gear in the starter, mechanical noise can be avoided when the engine is started due to good engagement precision, the service life of the starter is shortened, the engine cannot be started normally and even potential safety hazards are caused due to poor engagement. In the prior art, meshing detection needs to be carried out on an internal gear of a starter, a traditional contact detection technology generally adopts a contact spot detection method, a red lead powder, blue oil and other display agents are uniformly smeared on the tooth surface of the gear of the starter during detection, a manual disc is separated after a gear pair is driven for a plurality of circles, whether meshing is normal or not is judged by observing the distribution position, the area and the shape of the contact spots on the tooth surface, if spots are centered, the area is large, and the shape rule indicates that the meshing state is better, but only the meshing condition in a static state or a low-load state can be reflected, great difference exists between the meshing state and a high-load dynamic scene when the starter actually works, the detection result is difficult to accurately quantify, the judgment is carried out completely by experience of staff, the evaluation of the spot area has no unified standard, and the reliability of the detection result is poor. The method can also carry out point scanning along the theoretical tooth profile of the gear by means of high-precision coordinate measuring equipment, can acquire a plurality of geometric parameters reflecting meshing quality such as single tooth pitch error, tooth profile deviation, radial runout and the like, can accurately separate various error sources, is high in equipment price, is low in measuring speed, takes long time for complete detection, is not suitable for high-efficiency spot inspection of a production line, requires professional technicians to operate and read data, and further increases the detection cost.
