【正文】 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。孔的精度是指孔徑的精度，中心矩的誤差，各孔中心線的平行度與傾斜度。 齒輪制造精度對噪聲的影響。為提升裝配效率，常將調(diào)整點的尺寸規(guī)格進行標準化與系列化，以便在調(diào)整選用時方便快捷的選取。 關(guān)鍵詞： 后橋主減 噪音 主動錐齒輪 被動錐齒輪 大小軸承 差速器 1 背景 隨著各類車輛在人們生活和工作中應(yīng)用越來越普遍，人們對車輛噪音、震動、舒適性等要求也越來越高，車輛在行駛過程中由驅(qū)動橋單級主減速器在運行時產(chǎn)生的噪音是除了發(fā)動機以外另外一個較大的噪音來源，如果不進行有效的控制將影響駕或者乘人員的駕駛或乘坐舒適性。被動齒輪首先裝配在差速器殼體上，由于被動齒輪在差速器 殼體徑向的偏差會導致差速器裝配后被動齒輪與主動齒輪的間隙變化，所以被動齒輪安裝到差速器殼體時需要使用止口進行精確定位。為了降低齒輪噪聲，需從結(jié)構(gòu)設(shè)計與齒輪精度兩方面來考慮。[4] 輪體偏心偏重對噪聲的影響 。 [5] .

Working with high level of stability not only its own long life gear, and transmission of the shock, vibration, noise, also small, so the work of the stationary gear restriction error is the key to reduce gear noise. Smooth working of the accuracy of the noise. Accuracy of the work gear is required stability limits the instantaneous gear ratio changes, the error is occur several times per week to gear the corner of the error, it makes the process of generating gear in meshing impact, vibration, resulting in gear noise, it is a Species of the impact of highfrequency sound. For a gear for the stability of the factors that affect the work of the base section of his error and its involute error. Gears of noise exposure accuracy. Assessment of the accuracy of the posite indicator gear contact is contact spots, the noise exposure to bad gear will be greater. Cause tooth contact is not ideal because: Error in gear tooth length direction of the contact, the base section of deviation and direction of tooth profile error of contact. Motion accuracy of the gear noise. Gears transmit motion motion accuracy is the accuracy of the corner of gear per week to the maximum error value of the error can not exceed a certain limit. As a big cyclical motion accuracy gear (gear one revolution) error, while the ring gear by the gear in the gear rotating radial Zhou Jie accumulative error within a week will produce lowfrequency noise, but the cumulative pitch error increases, will result in Gears, and the impact of changes in angular velocity, then the noise increased significantly, and issued a rumblingsound. Emphasis on the body of the eccentric wheel noise. Emphasis on the body eccentric gear wheel meshing operation in the centrifugal force generated when the imbalance, A preliminary part of the development cycle was to determine the safety factors for anticipated operating conditions. Engineers utilized ADAMS simulation results to predict loads and evaluate design concepts before proceeding to the final design specifications. The initial concept design was analyzed via an ADAMS analysis of the automatic tensioners subjected to static and dynamic loads that can be expected from a frontend accessory belt dri
