油膜反馈可以大大降低静液ya轴承的刚度，但在机床的运行中，经常出现夹套、切槽、压力损失等现象。SKF轴承薄膜反馈是***重要的。在实践中，造成灌木***和毛发的主要原因如下：
Oil film feedback can greatly reduce the stiffness of hydrostatic ya bearing, but in the operation of machine tools, jackets, grooving, pressure loss and other phenomena often occur. SKF bearing film feedback is important for ***. In practice, the main causes of shrub death and hairs are as follows:
（1）薄膜的塑性变形；
(1) Plastic deformation of thin films;
（2）反馈慢。当外载荷突然变化时，当油膜不反转时，轴和套筒会产生摩擦。
(2) Feedback is slow. When the external load suddenly changes, when the oil film does not reverse, the shaft and sleeve will produce friction.
（3）胶片延迟。薄膜使用时间长，变形延迟，与反馈参数的变化成正比。
(3) Film delay. The film has long service time and delayed deformation, which is proportional to the change of feedback parameters.
通过增加薄膜厚度和使用一些耐用材料可以获得良好的效果。这SKF轴承通常是接受刚性薄膜、预压荷载和预留漏洞的关键。具体方法是：用4 mm厚的刚性薄膜代替1.4 mm厚的薄膜，在0.05 mm厚的下室垫层中，将轴承调整到比要求位置高0.05 mm。
Good results can be achieved by increasing film thickness and using some durable materials. This SKF bearing is usually the key to accepting rigid film, preloading load and reserving loopholes. Specific method is: 4 mm thick rigid film instead of 1.4 mm thick film, in 0.05 mm thick lower chamber cushion, the bearing is adjusted to 0.05 mm higher than the required position.
三。供油系统创新：
Three. Innovation of oil supply system:
在SKF轴承静液ya轴承供油系统中，除粗、细滤外，其它部件对静液ya轴承有保护作用。供油系统应在原有系统的基础上进行改造。
In the oil supply system of SKF bearing hydrostatic ya bearing, other components h***e protective effect on hydrostatic Ya bearing except coarse and fine filtration. The oil supply system should be reformed on the basis of the original system.
（1）压力继电器和压力表（以前在蓄能器前面）连接到储能面板后面的出口，例如允许操作员查看燃烧室压力和入口压力的大小。当压差大于定值时，可立即停机，防止衬套断裂。例如，入口压力为2兆帕，而出口室压力为1.2-1.6兆帕。如果入口压力低于1.2兆帕，机器将停止。
(1) Pressure relays and pressure gauges (formerly in front of accumulators) are connected to the outlet behind the energy storage panel, such as allowing operators to see the magnitude of combustion chamber pressure and inlet pressure. When the pressure difference is greater than the fixed value, the machine can be stopped immediately to prevent bushing from breaking. For example, the inlet pressure is 2 MPa, while the outlet chamber pressure is 1.2-1.6 MPa. If the inlet pressure is less than 1.2 MPa, the machine will stop.
（2）数字生长检测装置：
(2) Digital growth detection device:
耐磨静电轴承主轴与轴瓦间隙为0.04-0.05mm。间隙中的油具有一定的阻力值。如果检测到电阻值变化，则可以知道时间间隔。以主轴为一极，衬套为另一极，测量电阻变化。经过处理后，信号送至光电bao警控制系统放大器，控制SKF轴承主轴电机的启动和停止，以停止轴与轴套之间的摩擦。
The clearance between wear-resistant electrostatic bearing spindle and bearing bush is 0.04-0.05 mm. The oil in the clearance has a certain resistance value. If a change in resistance value is detected, the time interval can be known. Measure the resistance change with the spindle as one pole and the bushing as the other pole. After processing, the signal is sent to the amplifier of photoelectric Bao alarm control system to control the start and stop of SKF bearing spindle motor to stop the friction between the shaft and the sleeve.
孔贾tou票：
Kongjiatou Ticket:
（1）将静液ya轴承的内部储蓄改为外部储蓄，增加压力表，并立即显示上下腔的压力。
(1) Change the internal s***ings of hydrostatic Ya bearing to external s***ings, increase the pressure gauge, and immediately display the pressure of upper and lower chambers.
为了便于维修，特别是定期清洗，它与内部省煤器是***的。
In order to facilitate maintenance, especially regular cleaning, it is incomparable with the internal economizer.
（二）储蓄率。储蓄率β的理论值介于1.2和1.5之间。根据多年的经验，***好是1.25。例如，在维修时，bi须严格控制轴承、前后衬套、同轴度、圆度和锥度的精度，以保证β值。根据机床的承载能力，确定E值（主轴和轴承套的中xin优先级），使β值***佳。
(2) S***ings rate. The theoretical value of s***ings rate beta is between 1.2 and 1.5. Based on years of experience, *** is good at 1.25. For example, in maintenance, Bi must strictly control the accuracy of bearing, front and rear bushing, coaxiality, roundness and taper to ensure the value of beta. According to the load-carrying capacity of the machine tool, the E value (middle Xin priority of spindle and bearing sleeve) is determined to make the beta value *** better.
（3）当每个油室内没有SKF轴承主轴时，每个出油口的油柱bi须相同（检查方法）。当两者相差相等时，应接受挡板式省煤器开度的关键点，改变流量。
(3) When there is no SKF bearing spindle in each oil chamber, the oil column Bi of each oil outlet must be the same (inspection method). When the difference between the two is equal, the key point of baffle economizer opening should be accepted and the flow rate should be changed.
