2 common Plain Bearings1, split bearings split bearing, the bearing housings, bearing caps, bushing (divided into upper and lower tile) and connecting bolts and other components. Subdivision bearing surface should be close to vertical loading direction, most bearing surface is split level, there are oblique.Bearing cap and bearing of the subdivision surface often Zuocheng ladder for work positioning and prevention of dislocation.

1: ntn bearing performance:1.ntn bearing stiffnessntn bearing stiffness, is ntn bearing power generating units, the size of the required deformation. Rolling of elastic deformation is small, in most machines do not have to be considered, but in some machines, such as machine tool spindle,the bearing stiffness is an important factor, the general should be used cylindrical and tapered roller bearings. Because these two types of bearings and loaded

Roller bearing frequent minor injuries, such as inventory, the creation of small water rust, and transport processes of small micro-abrasion, repair easy and wasteful to discard such cases. In addition to economy outside the repair bearings are the technical, requiring mender fully understand the technical requirements of the corresponding bearings,and bearings and parts thereof in structure, process and material characteristics on the otherwise difficult to ensure that repairs are bearing meet the required results

1: ntn bearing speed operation:1. Analysis of cage material type (for high-speed rotation, suitable for cutting copper alloy or phenolic resin cage system. There is also suitable for high-speed rotation of synthetic resin molded cage)2. Analysis of Lubrication (used for high-speed spin cycle lubrication, spray lubrication, oil mist lubrication and oil lubrication Lubrication)3. Of bearing internal clearance (taking into account the bearing temperature rise generated internal clearance reduction)

ntn Bearing selection of 4 Note1, carbon steel, high enough intensity, the lower the stress concentration sensitivity, easy to carry out a variety of heat treatment and mechanical processing, low price, supply adequate and there are the most widely used.The imports of general machinery bearings are available in 30,40,45,50 and other brands of high-quality carbon steel, particularly steel 45 after quenching the most commonly used.
 

1: ntn bearing different Sound Detection:1., Vibration detection method: It is unusual sound of an indirect detection methods, detection can be divided into qualitative and quantitative parameters of detection. Among them, qualitative detection method is divided into monitoring and observation of abnormal sound vibration wave method

ntn bearings in high speed rotation, in particular the speed close to or exceeding the limits of record size of the table speed, the main should pay attention to the following(1) The use of precision bearings;(2) Analysis of the internal bearing clearance (taking into account the bearing temperature rise resulting reduction in the amount of internal clearance);(3) analysis of cage material type (for high-speed rotation, suitable for cutting copper alloy or phenolic resin cage system.
