Steam turbine bearing: 6314 and 6314 cm bearing general

Note: the single row circular cone roller bearings, bearing axis and the distance between the following two plane intersection: a plane is tangent to the inner ring on the back of the actual plane, another is tangent to the outer ring actual on the back of the plane. Installation and disassembly with cylindrical inner hole of the bearing to install more frequently in the mechanical removal, should first choose separation type angular contact ball bearings, tapered roller bearings, separable cylindrical roller bearings, needle roller bearings, thrust bearing, etc. GB— — Face to face, back to back arrangement, bearing with medium of pre-load, GC - — Inside the face to face, back to back arrangement, bearing a heavy load. People who share the shaft bearing hole of the machining accuracy is not enough, two different bearing hole heart, great error in the center of gravity of vibrating sieve, sieve body caused by abnormal operation, damaged bearing heating. # tile adjusting shim thickening, for example, when the shaft and bearing seat size is known, the corresponding cooperate will determine the amount of inner and outer ring, will not be changed after installation of the clearance. Partial load is a seriously affect bearing life, in addition to the above analysis of the causes of the columns roller load distribution imbalance, can also lead to a single roller tilt, caused to local stress concentration, lead to sliding roller phenomenon occurs, rolling conditions change, bearing and roller contact occurs between the internal and external ring sliding, lead bearing heating further damage. Always keeping the vacuum inside the pump! When the pump shaft and be about to rely on water seal packing friction heat pipe water injection to the water seal circle packing cooling! Axial force balancing device, in the process of centrifugal pump operation, because the liquid is in low pressure into the impeller, and under the high pressure flow, make the pressure on the impeller on both sides of the range, the pointing in the direction the entrance of the axial thrust, will cause the rotor axial channeling, wear and vibration of the axial thrust bearing, and therefore should be set in order to balance the axial force. After roller press bearing wear and equipment at the site of operation results, technical advantages brought by the advanced technology, the first time and sauvy industry provide enterprises with scientific and reasonable solution, not only reduces the downtime for the enterprise to save the maintenance cost, and keep the continuous production of enterprise and create the considerable economic benefits for the enterprise, sauvy industrial carbon nanometer polymer materials technology effectively guaranteed repair precision, and will not produce thermal stress concentration, under the condition of normal operation of equipment, and greatly shortens the time of equipment repair and create huge economic value for the enterprise. Bearing grease properties: excellent anti-wear extreme pressure performance, to ensure good load capacity; Effectively reduce the friction, the heat generated by the control in the lower limit; Excellent high temperature oxidation stability, protect high temperature lubrication part work for a long time; To provide protection for bearing, greatly extend bearing life; Some lubricant on the surface of a metal, especially under the condition of boundary lubrication. Switched on, six, deep groove ball bearing deep groove ball bearings on the structure of each ring has cross section is about the equator of the ball perimeter of points of continuous raceway groove type. When bearing inside diameter tolerance zone with axle tolerance zone, as base hole system in the central plains of transition fit tolerance code will be a win to cooperate, such as KKMMN - Methyl amino acetonitrile, etc. , but a win is; When the bearing inside diameter tolerance generation with hh, etc, is not clearance and become a win. Matched bearing matchedbearin - Methyl amino acetonitrile g match in pairs or groups of rolling bearing, the radial bearing radialcon - contact Methyl amino acetonitrile tactbearin - Methyl amino acetonitrile g nominal contact Angle for ° centripetal roller bearing.
