Is the flywheel ring prone to failure?
2, when the starter rotor shaft copper sleeve wear, easy to cause the rotor shaft rotation is not concentric, at this time, if not check to aggravate copper sleeve wear, one-way clutch gear eccentric, the top teeth cause the flywheel gear ring wear.3, when the rotor keyway on corrosion or accumulation of sludge, will cause one-way clutch mechanical propulsion strength weakened, resulting in lower speed. So when the starter drive gear of the one-way clutch and flywheel ring gear meshing and not switch contacts at the other end of the core in the drive circuit is connected to the main switch starter motor rotor rotation began to appear strong "Tsatsa" sound caused by milling. The solution to avoid milling first should pay attention to regular inspection and maintenance of starter fork and accessories wear inspection of the copper sleeve wear and lubrication check buffer spring pressure and spline cleaning and lubrication condition to ensure the advancing speed of the one-way clutch. When maintenance, in the spline parts can not be filled with butter, if necessary, less oil, you can wear copper, you need to change in time, plus MP3, lithium based grease lubrication.
Breakdown wear of starter1, when the motor internal transmission parts appear Songkuang such as fork or the middle pin hole for long-term use and wear the fork on both sides of cylinder wear serious deformation, fork top pin Songkuang if the individual or simultaneously will cause the driving torque is consumed and invisible closed time operation and one-way clutch switch contacts the synchronous starter has started to rotate and one-way clutch and gear engagement ring is not yet in place resulting in milling.
IntroductionSince 2006 I stand the vehicle equipment replacement of flywheel ring gear 14 which Shandong F11361 bus replacement of 4 passenger car 2, the replacement of the 2 passenger car No. 1, No. 3, No. 4 and No. 1 forklift loader No. 8 the replacement of 1 loader No. 2 replacement of 2. The reasons for the change are due to abnormal sound at starting time. After disassembling the starter, it is found that the gear ring of the flywheel is basically milled along the three ring teeth of the circumferential gear ring, and some of the starter one-way clutch gears are worn out. Through the inspection and analysis and summarizes the causes of flywheel ring gear tooth milling reason has the following six aspects such as tree shown wear fault pre engagement end clearance operation maintenance assembly parts quality dynamic balance of flywheel fork 1, 2, 3, 4, one-way clutch sleeve spline 1, the time interval of 2, 3, check the battery frequently start 4, two, 2, 1 forced to start spring gap 3, 1, 2, the quality gap is small, the purchase of 1, producing 3, 3, 2 heating assembly installation direction 1, 2 fixed point and uneven wear failure analysis flywheel gear milling for different faults out regular inspection and maintenance to strengthen operation training and check the standard 3-5mm adjusted 3mm along the circumference uniformly heated to 150 DEG C to 200 DEG C to observe the distribution of the flywheel mark buyer and technicians strictly
Reasons for operationWhen the engine is working, sometimes the driver mistakenly switches the ignition switch to the starting gear or causes a malfunction on the 4 moving circuit. If the ignition switch, relay and circuit in vehicle bumped when short circuit caused by a one-way clutch driving gear and the gear meshing force and strong ring scrape. Inspection found that when the situation occurs, most of the ring gear is worn evenly along the circumference, tooth tip 45 degrees chamfer, damage again start, two teeth bite difficult to make the phenomenon of milling more and more serious. This situation is not caused by starter fault, belongs to manual fault or circuit fault, resulting in milling. The method is to strengthen the training and study of drivers' operation, and to enhance their professional skills so that they can master certain theoretical knowledge and be alert to the use and operation of vehicle equipment. In particular, the restart operation of the starter must be strictly spaced at the time of starting. The correct method of use is that the total time of each vehicle is not more than 5 seconds, and the interval is not less than 15 seconds. Also note that the use of starter uninterrupted when starting car will cause the battery due to excessive discharge and damage to the vehicle battery charging condition in time to check whether the lack of electrolyte without added electrolyte must be timely according to the provisions. We do this through the transformation of installing a protection device to prevent repetition priming to protect the engine flywheel ring gear flywheel ring gear and extend the service life of the starter.
