Imported bearing based on the basic performance requirements to develop new applications

Traditional oil import bearings: because of the travel the advantages of low noise, self-lubricating, oil import bearing has become the latest must-haves in the computer CPU fan import bearings, market demand is big; In addition, as people more and more high to the requirement of noise, oil import bearing application in daily household appliances are also expanding. Imported bearing depends largely on the basic requirement for the materials imported bearing performance. Select manufacturing rolling bearings imported materials are appropriate, the use of performance and life will have a significant impact. Under normal circumstances, the rolling bearing import is the main damage form under the action of alternating stress fatigue spalling, and the imported bearing precision loss due to friction and wear. In addition, there is crack, indentation, corrosion causes such as imported bearings of non-normal damage. Rolling bearing import, therefore, should have high ability to resist plastic deformation, less friction and wear, good rotation accuracy, good dimensional accuracy and stability, as well as the long contact fatigue life. Performance and some of them are jointly decided by the material and heat treatment process. First, the size of the restrictions. Usually bearing can device space is restricted. In a large minority of condition, the diameter of axle ( Or bearing inside diameter) Is designed on the basis of mechanical design or other restrictions. So bearing type and size of the choice is based on the inner diameter of the bearing and resolution. As a result, the secondary dimension table are based on standard bearing inside diameter size and compiled by the international norms. A single specification size of bearing way, in the machinery installation design is best used when bearing ( This design to the bearing can be easy to sell, just as an aside, here model does have some bearing on the catalogue, but some non-standard bearing big sea area in China without spot, futures at the some time will be a long time, so should think when bearing selection time of the change and the capital asset) Bearing load, the load on the bearing, the nature, size, direction is changeable. Usually, additional load on the dimension table are displayed. Axial load and radial load, and so on, but also important element is to select suitable bearing. Phase in advance when the size of the ball and needle bearing, needle roller bearing usually have higher load ability and accept the larger vibration and shock loads. Speed, allowing the speed is based on the imported bearing type, size, precision, adhere to the aircraft type, load, smooth, and cooling elements. Bearing table lists the specifications precision bearings under the oil and grease smooth smooth speed is allowed. Usually, deep groove ball bearings, automatic self-aligning ball bearings and cylindrical roller bearings are suitable for high-speed operation. Bearing tolerance, bearing dimensional accuracy and rotation accuracy is based on ISO and JIS standard. Advice about machines, high-precision and high-speed operation using precision grade 5 or above import bearings, deep groove ball bearings, angular contact ball bearings and cylindrical roller bearing is suitable for high precision mechanical operation. Rigidity, when bearing rolling element and raceway contact pressure, elastic deformation will happen. Some mechanical demand minimize elastic deformation. Roller bearing is smaller than ball bearings of elastic shape variables. In addition, in some cases imported bearing exerted to the pressure to add rigidity. This order is typically used for deep groove ball bearings, angular contact ball bearings and tapered roller bearing inner and outer circle bias, shaft bending, shaft or the bearing box tolerance changes, matching error will incur inside and outside the circle of the fair. In order to avoid unfair Angle through the large, automatic self-aligning ball bearings, automatic self-aligning roller bearings, or self-aligning bearing seat is a better choice. Voice frequency and distance, is all according to the high precision rolling bearing specifications made in consumption, so the voice and the torque is small. Deep groove ball bearings and cylindrical roller bearing used for low voice, low torque places with special requirements. Device and assembly, some use place needs often assembly and device, to ensure that the demand to stop testing and servicing. Can distinguish different devices on inner and outer bearing such as cylindrical bearings, needle roller bearings, and tapered bearing is very suitable for this place. Taper groove of automatic self-aligning ball bearing and spherical roller bearing with the help of shaft sleeve, strange device simplifies the order.
