在车轴螺纹部分安装主动皮带轮的部件是客车发电机三角皮带-减速箱-万向轴传动装置的主要部件之一。该部件用于固定传动装置的主动皮带轮、传递扭矩和固定轴箱部件的轴承。在批量生产的成套部件(图1)中包括主动皮带轮1、尾部锥形的M110专用螺母4、挡板6、带迷宫密封和密封圈2的固定盖3、键7。用两个螺栓5固定在轴颈上的挡板6是止动元件,不传递扭矩。在端部用垫圈8、螺母9和开口销10固定主动皮带轮。为了固定拆卸工具在主动皮带轮上有三个螺栓11。
One of the main components of the V-belt-gearbox-cardan shaft transmission for passenger car generators is the part for mounting the drive pulley to the threaded portion of the axle. This part is used to hold the drive pulley of the transmission, transmitting torque and bearings that hold the axlebox components. The mass-produced kit (Fig. 1) includes the drive pulley 1, tail cone-shaped M110 special nut 4, baffle 6, fixing cap 3 with labyrinth seal and sealing ring 2, key 7. The baffle 6, fixed to the journal with two bolts 5, is a stop element and does not transmit torque. At the end, the drive pulley is fixed with a washer 8, a nut 9 and a split pin 10. For fixing the removal tool there are three bolts 11 on the drive pulley.
