轴承座及齿轮箱是机械传动的重要组成部分。对于阻止液体介质沿轴伸出设备之外的泄漏问题,在常温、低压的情况下,目前采用接触式填料密封最为普遍,但效果较差,特别是填料磨损后,泄漏更为严重。如图1所示,当轴承在高速旋转时,液体润滑油沿固有轨迹向两侧轴向喷射,加之轴在允许偏心范围内周期性径向跳 Bearing housing and gear box is an important part of mechanical transmission. For preventing the leakage of liquid medium out of the shaft along the shaft, the contact packing is most commonly used at room temperature and under low pressure, but the effect is poor. Especially when the packing is worn, the leakage is more serious. As shown in Figure 1, when the bearing rotates at a high speed, the liquid lubricating oil is axially injected along both sides of the inherent trajectory, and the shaft is periodically radially levitated within an allowable eccentric range
