SL cross slider coupling

The SL cross slider coupling is also known as the metal slider coupling. It consists of two half couplings with radial grooves on the end faces and a middle slider with a tenon at each end. The two ends of the middle slider are The tenons are perpendicular to each other, and they are respectively embedded in the grooves of the two half couplings to form a moving pair. If the measuring axis is not concentric or skewed, the slider will slide in the groove during movement, so the groove and the slider Lubricant should be added to the working surface of the shaft. If the two shafts are not concentric, when the speed is high, the eccentricity of the slider will produce a lot of centrifugal force wear and bring additional load to the shaft and shaft. Therefore, it is only suitable for low speed and transmission Large load occasions.

Oldham coupling零件的材料可用45钢，工作表面需要进行热处理，以提高其硬度；要求较低时也可用Q275钢，不进行热处理。为了减少摩擦及磨损，使用时应从中间盘的油孔中注油进行润滑。十字滑块联轴器又名金属滑块联轴器，其滑块呈圆环形，用钢或合金制成，适用于转速较低，传递转矩较大的传动。十字滑块联轴器由两个在端面上开有凹槽的半联轴器和一个两面带有凸牙的中间盘组成。因凸牙可在凹槽中滑动，故可补偿安装及运转时两轴间的相对位移。 因为半联轴器与中间盘组成移动副，不能发生相对转动，故主动轴与从动轴的角速度应相等。但在两轴间有相对位移的情况下工作时，中间盘就会产生很大的离心力，从而增大动载荷及磨损。因此选用时应注意其工作转速不得大于规定值。 这种联轴器一般用于转速n<250r/min，轴的刚度较大，且无剧烈冲击处。
