江苏skf轴承开发了一种鼓式电动方向盘（eps）。它的重量比原来的重量轻13%。通过仿真对强度和刚度进行了调整，并对主要部件江苏skf轴承进行了小型化。它重约5公斤，是世界上***轻的倾斜齿轮。2017，轻型卡车将遍布世界各地。
the skf bearing of jiangsu has developed a drum type electric steering wheel (eps). its weight is 13% lighter than the original weight. the strength and stiffness were adjusted by simulation, and the skf bearing of the main component jiangsu was miniaturized. it weighs about 5 kilograms and is the lightest tilted gear in the world. 2017, light trucks will spread all over the world.
虽然江苏skf轴承省略了照片，但配备有减速齿轮和扭矩传感器的变速箱也通过小型化轻量化。
although the skf bearings in jiangsu are omitted, the gearboxes equipped with speed reduction gears and torque sensors are also lightweight through miniaturization.
江苏skf轴承鼓式电动助力转向系统。当驾驶员转动方向盘时，安装在转向轴上的扭矩传感器将检测到扭矩。通过使用ecu（电子控制单元）来计算改变轮胎角度所需的扭矩，并且由电机产生的扭矩不足。
jiangsu skf bearing drum type electric power steering system. when the driver turns the steering wheel, the torque sensor installed on the steering shaft will detect the torque. the torque required to change the tire angle is calculated by using the ecu (electronic control unit), and the torque generated by the motor is insufficient.
小型化是江苏skf轴承鼓式eps的主要组成部分，即扭矩传感器、减速齿轮和存储这些部件的齿轮箱。
miniaturization is the main component of jiangsu skf bearing drum eps, that is, torque sensor, reduction gear and gear box for storing these components.
（a）减速齿轮。
(a) deceleration gear.
（b）线圈和c套筒形成扭矩传感器。采用模拟技术减少不必要的零件重量。
(b) a coil and a c sleeve to form a torque sensor. analog technology is used to reduce unnecessary parts weight.
扭矩传感器由轴（输入轴、输出轴）、套筒和线圈组成。
the torque sensor is composed of shaft (input shaft, output shaft), sleeve and coil.
江苏skf轴承输入轴与输出轴之间的扭杆用于检测扭矩。在输入轴的顶部设置有窗口孔的套筒，在套筒的外侧设置有线圈。套筒的内侧是由有槽转子连接的输出轴。当输入轴的套筒变形时，套筒的孔和转子的位置发生变化，磁场改变。根据磁场的变化检测转矩。
the torsion bar between the skf bearing input shaft and the output shaft of jiangsu is used to detect torque. a sleeve with a window hole is arranged at the top of the input shaft, and a coil is arranged on the outer side of the sleeve. the inner side of the sleeve is an output shaft connected by a grooved rotor. when the sleeve of the input shaft is deformed, the position of the hole and rotor of the sleeve changes and the magnetic field changes. the torque is detected according to the change of the magnetic field.
通过江苏skf轴承缩短轴的直径，减小了线圈周围的直径。轴减少19%，套筒减少60%，线圈减少49%。扭矩传感器总体减少了24%。
the diameter of the shortening shaft is reduced by the skf bearing of jiangsu, and the diameter around the coil is reduced. the shaft is reduced by 19%, the sleeve is reduced by 60%, and the coil is reduced by 49%. the torque sensor overall reduced by 24%.
江苏skf轴承减速齿轮的直径减少了15%。通过对减速器齿轮齿的分析，实现了应力分散，实现了小型化。
the diameter of jiangsu skf bearing reduction gear has been reduced by 15%. through the analysis of gear teeth of reducer, the stress dispersion is realized and miniaturization is realized.
变速箱是用于江苏skf轴承安装电机输出轴和扭矩传感器轴的情况，还包括车辆安装点。通过将厚度从0.5mm减小到3.0mm，减少了23%。江苏skf轴承委托设计和制造齿轮箱为模具制造商。这一次，我们亲自购买了模具制造设备，并优化了设计。即使厚度减小，也可以保证相同强度的强度和刚度。
the gearbox is used for the installation of motor output shaft and torque sensor shaft of jiangsu skf bearing, and also includes vehicle installation points. by reducing the thickness from 0.5mm to 3.0mm, it is reduced by 23%. jiangsu skf bearing commissioned the design and manufacture of gearboxes for mold manufacturers. this time, we bought the mold manufacturing equipment in person, and optimized the design. even if the thickness is reduced, the strength and stiffness of the same strength can be guaranteed.
