The utility model discloses a new type of bolted split universal joint, which mainly comprises a cross shaft, through-hole bearing seat, dust-proof cover, oil seal, needle retaining ring, needle roller, gasket and round bearing bowl. The cross shaft consists of four journals, one set of bearings is assembled on each journal, and a total of four sets of bearings are assembled. The round bearing bowl in each set of bearings is pressed into the through-hole bearing seat by interference fit, and the round bearing bowl is pressed into the through-hole bearing seat. A semi-closed bowl-shaped structure with cylindrical holes excavated in the middle is equipped with gaskets at the bottom of the cylindrical hole of the cylindrical bearing bowl. A whole circle of needles is evenly arranged in the circumferential direction of the inner wall of the cylindrical hole. The oil seal is pressed into the oil seal at the opening of the cylindrical hole. A needle-roller retaining ring is placed between the oil seal and the needle-roller, and a dust-proof cover is arranged outside the cylindrical hole. The utility model simplifies the installation mode of the universal joint assembly and the transmission shaft, facilitates assembly, simplifies the manufacturing process of the transmission shaft joint fork parts, reduces the manufacturing difficulty, solves the problem of too small enclosure area of the clamp spring universal joint, reduces the weight of the transmission system, thereby improving the NVH performance of the vehicle and reducing fuel consumption.
【技术实现步骤摘要】
一种新型螺栓连接分体式万向节
本技术涉及万向节的领域,具体涉及一种新型螺栓连接分体式万向节。
技术介绍
现有万向节总成与传动轴节叉连接方案一般为卡簧固定,万向节轴承碗为圆形,与传动轴节叉孔过盈配合,轴向采用卡簧卡紧,根据卡簧位置不同,分为内卡式、外卡式两种。此方案的连接方式在装配时,十字轴需要预先套到叉孔中,然后将已预先装配好滚针、油封等附件的轴承从叉孔外侧压入叉孔,最后装配卡簧。现有技术方案传动轴节叉零件形状较复杂,从锻造到加工都有一定难度。装配步骤也较为繁琐,需要借助压力机压装,还需装配卡簧。连接零件较多,整个结构重量较大,导致整个传动系统转动惯量大,对整车NVH、油耗等都有不利影响。现有技术方案装配万向节时需要将十字轴预先套到叉孔中,这就对叉孔与十字轴相互尺寸有了制约,为了十字轴能顺利装入节叉孔,节叉往往需要切去一部分,切去的部分导致叉孔对轴承碗包容面的减小。轴承碗是薄壁零件,较小的包容面是不利因素。
