- Q:sometimes to the other bearing sliding bearing number, sometimes to the sliding bearing parts inside, why?
- Sliding bearing partsThe bearing is sliding bearing and shaft parts, very smooth, generally made of bronze, anti friction alloy wear-resistant material, in particular, can be made of wood, plastic or rubber.
- Q:What are the five types of bearings? Like F~G...? What else? Who knows?
- 6 categories: angular contact ball bearings, four point contact ball bearingsThe 7 category: tapered roller bearingsThe 8 Category: thrust ball bearings9 category: thrust roller bearingsPure hand-made, adopt landlord
- Q:Is there any difference between plain bearings and other bearings?
- Bearings are nothing more than sliding bearings and rolling bearings, sliding bearings without moving coil, a shaft directly contact the shaft, the shaft will be worn, rolling bearings can roll the moving coil, and the shaft is connected, the shaft will not wear.
- Q:A bearing assembly that can withstand greater torque (other requirements are not required and the axle is cantilevered)
- Torque? Bearings are not used to bear torque, mainly to bear axial or radial load
- Q:Characteristics of cross roller bearings
- 4, substantial savings in installation spaceThe size of the inner and outer ring cross roller bearing is miniature minimal, especially ultra-thin structure is small size close to the limit, and has high rigidity, so the most suitable for industrial robot joints or rotating parts, machining center of the rotary table, the robot rotating parts, precision rotary table, medical instrument IC, measuring equipment, manufacturing device widely used.5., high speed capacity6. reduce the shaft length and processing costs, thermal expansion leads to limited changes in geometric size7. 、 adopt nylon separator, low rotating inertia, low starting torque, easy to control angle division8., optimize pre tightening force, stiffness, guide roller running high accuracy9. carburizing steel provides excellent impact resistance and surface abrasion resistance
- Q:What are the advantages of ceramic ball bearings versus other bearings?
- 1, insulation bearings;2, light weight, less heat, you can have higher working limit speed.
- Q:What are the world bearing giants?
- International bearing giants:Sweden: SKF (SKF group)Germany: INA/FAG (Schaeffler group)United States: TIMKEN (The Timken Company)Japan: NSK (Nske) NTN (NTN) KOYO (Guang Yang) NACHI (fujikoshi)NMB (Mei Beiya) THK (main line, unit FYH (bearing) main bearings etc.)
- Q:Are there any differences between bearings used on fans and other ordinary bearings?
- If the model is the same, it makes no difference.From the point of view of the category, there are more taper and more heart in the gearbox;
- Q:Bearings radial, in addition to the location of contact with the box, there is no other way?
- 2. the outer ring of the bearing outer ring of the bearing outer ring is arranged in the outer hole of the outer shell, and the inner side of the outer hole of the outer shell generally has the position of the shoulder fixed bearing, and the other side is positioned with an end cover, a thread ring and a hole, and an elastic ring ring. (1) the end cover positioning end cover is used for all kinds of radial bearings and angular contact bearings. When the bearing speed is higher and the axial load is larger. The end cover is positioned and pressed with a screw to compress the outer ring of the bearing, and the end cover can also be made into a labyrinth sealing device. (2) thread ring bearing high positioning speed, axial load, not suitable for use under the condition of end cap positioning, available thread ring positioning radial bearing and thrust bearing, this can be used to adjust the axial clearance of the bearing. (3) the axial position of the elastic ring positioning method is small, the installation and disassembly are convenient, the manufacture is simple, and the utility model is suitable for bearing smaller axial load places. An adjusting ring is added between the bearing and the spring, so that the axial position can be adjusted conveniently. (4) the deep groove ball bearing with a stopping groove on the outer ring of the bearing can be fixed by the retaining ring. This type shall be used when the inside of the housing hole cannot be machined because of the condition limit, or the part must be reduced in outline size
- Q:Bearing, in addition to interference, excessive, gap three kinds of co-ordination, there are no other coordination?
- These three types of coordination, and other coordination is only a different individual name, but the actual situation is the same
