Key words: After the main by the bridge Noise Driving Bevel Gear Passive bevel gear Bearing size Differential 1 Background With the various types of vehicles and work in people39。s lives more and more popular, people vehicle noise, vibration, fort and other requirements are also increasing, The 5PK belt segment of length 40mm is pressed against theplate, which has identical grooves to the pulley for the Ksection belts. The pression of the belt segment and the grooved plate was achieved with a universal Zwick/Roell Z050 testing machine in the temperature chamber. The tests were conducted at four different temperatures, which enabled us to determine the influence of the temperature on the mechanical properties of the belt rubber. In Fig. 12 the pression force versus the deformation of the belt segment is presented. It can be assumed that the main deformation of the belt segment is due to the deformation of the soft friction rubber layer. Temperatures up to 80176。 C have practically no influence on the mechanical properties of the rubber layer, and hysteresis can be observed during the loading and unloading phases. the vehicle by the driver in the process of moving the bridge singlestage main gear box at run time In addition to the engine noise is larger than other noise sources, if not effectively controlled by officers will affect the drive or driving or riding fort. For the single stage on the main gear axle for effective noise control, structural features of their products according to the type of final drive and the noise generated in the product realization process for process control. [1] 2 Noise Type Singlestage main gear axle in the work process, the torque from the drive shaft bevel gear to pass through the active to passive gear, driven gear by the number of bolts fastening the differential case, the passive gear torque through the semiPassed to both sides of the axle shaft gear to achieve the purpose of driving traffic. In the final drive that may arise during the work of the noise is divided into six types: flange connection with the shaft rotating at high speed the noise generated by resonance。 small bearing rotating the noise。 large bearing rotating the noise。 Side gears and plaary gears rotate the noise。 active and passive noise when rotating gears。 spline side gears and axle shaft with intermediate rotation noise. [2] 3 Factors and Countermeasures generated Final drive work with different types of noise may also occur which may occur only a certain category or categories, in order to effectively control the noise of all links in the need for effective process control, for possible Noise from the operation of link analysis and take an adjustable product realization solutions in order to later quickly after the product can be easily adjusted to control the noise. According to generate different types of noise, a mon production process control methods are: Adjust the spline flange intermediate and active relationship with the spline gear Because the pression flange is the role of small bearings, offset by the running gear in the axial force in the selected flange so the internal nature of the spline with the need to select the transition with little to ensure that the locking nut Effectively locked when the axial force transfer. Adjust the small gear bearing inner ring and the coordination To facilitate installation and maintenance is currently a small part of the final drive gear bearing inner ring and the nature of the cooperation with such a small space for easy installation and with oil seals for the main gear, but if the work in the main gear with the use of small space, when the initial Flange when the sudden passing of torque transfer to the driving gear, but small relative to the bearing inner ring measures will occur at this time moving, which measures the thickness of moving to block oil pan easily lead to increased wear and tear loose the small bearing axis, resulting in noise . If for small gap with the bearing inner ring gear rotation generated block oil pan gasket or sleeve
