Reasons for Failure of Traction Gear Transmission Traction gear transmission failure begins with wear, and its wear is mainly due to abrasive wear, fatigue wear and adhesive wear. Increasing the service life of the traction gear is to prolong the time of its stable wear. Practice has proved that the lubrication condition of the traction gear and the working temperature have a great impact on its life. Under a certain number of cycles, the surface of the tooth may crack and expand, and eventually break due to fatigue wear. The traction gear is poorly lubricated, and impurities such as sand metal chips are trapped in the lubricating oil, which is easy to cause abrasive wear. In addition, the oil leakage of the gear cover and the low oil level will cause dry grinding of the gear teeth to accelerate wear and premature failure. High operating temperatures also disable the traction gear drive. When the locomotive traction heavy-duty train runs at high speed, the traction between the tooth surfaces is also increased due to the large traction force, and the relative sliding speed is high, so that an instantaneous high temperature is generated at the meshing of the tooth surfaces, and the two tooth surfaces are adhered. When the friction surface is relatively slid, the tangential force will cause the adhesion point to be cut, and the torn metal swarf will stick to the friction surface to form a surface protrusion, which further causes the surface to wear, that is, so-called adhesive wear occurs. Improvement measures For the uneven force of the gears, the following measures are taken to ensure the normal lubrication of the bearing bushes, try to use a small radial clearance, strictly check the tooth shape with the sample plate, ensure the normal meshing of the gear teeth, and prevent shock and vibration. After being converted into direct current by the silicon rectifying device and sent to the DC motor, the synchronous motor is driven by the DC motor to realize grid-connected power generation. The waste heat is used to pass the intercooler cooling water and the lubricating oil through the heat exchanger, so that the cold water becomes hot water and is used by the station house or some workshops. After many years of testing, the diesel engine test station proved to have the following advantages. In terms of preventing noise pollution and improving working conditions, the requirements set by the state have been met. The diesel generator set test vehicle has a simple structure, flexible operation and small vibration, which can meet the test requirements. Diesel engine air intake filter system cooling system electronic control system overspeed protection device temperature and pressure instrument slewing device and other structures are reasonable, reliable operation, and relatively novel design.
