LNSERTED bearing surface of the bearing housing bore requirements and the installation location, low surface roughness, shape and position accuracy as possible, resulting in bearing stiffness is also higher. The surface of the surface hardening treatment, help to improve rigidity.
Deformation measurement can be used as a dial indicator on arrival bearing surface or in its pretension load method of reading and observed changes in the appropriate parts of the shaft. Preloading method has its negative aspects, such as FAG bearings friction torque increases, the temperature rises, shortened life expectancy, etc., so to fully consider and weigh the pros and cons, choose the appropriate amount of preload.
With advances in technology, the development trend of heat treatment technology is mainly reflected in the following aspects: Clean heat treatment production formation water, waste gas, waste salt, oil and electromagnetic radiation etc. pollute the environment. Solution heat treatment of environmental pollution problems, the implementation of clean heat treatment (also known as green heat) is the direction of the development of heat treatment technology. This atmosphere heat treatment, quenching oils and cleaning equipment are made of high requirements.
Vacuum heat treatment, the workpiece is more fine and uniform microstructure, surface and heart tissue consistent, uniform hardness is conducive LNSERTED bearing fatigue life improvement. Vacuum furnace is mainly used in special steel heat treatment (heating temperature at 1 000 ℃ above) and some require a higher steel GCr15 bearing parts LNSERTED quenching, in the field of heat treatment of bearing a wider application. Vacuum furnace trend is UHP gas instead of oil quench hardening, and the application of vacuum carburizing furnace, etc. In order to solve new kinds of steel LNSERTED bearing fields.
Inspection LNSERTED bearing grease metamorphic approach in the use of the process of FAG bearings, grease is critical. If you use a grease deterioration not only achieve its proper role, away will damage the bearings. Today, I'll examine whether the bearing metamorphic way to tell everyone. Oil flow observation take two measuring cup, one containing the lubricant to be checked, the other empty on the table, will be filled with oil cup held high 30-40 cm away from your desk and tilt, allow oil slowly flow empty cup, to observe the flow of good quality lubricating oil flow should be slender, uniform, continuous, if there is oil flow unsteadiness, sometimes with large shed, then say oil has gone .
Droplets traces of take a clean white filter paper, drip a few drops on the filter paper until oil leaks, if the surface has black powder, a resistive touch astringent sense, then the oil inside the impurities have been many, a good lubricant without powder, hand feels dry and smooth, and yellow marks.
LNSERTED bearing gear is actually a rolling bearings, FAG bearings shift practical for high-speed aircraft, machine tools and heavy load of trains, cars, and daily use of trucks, rickshaws rotating spindle can reach the more loaded Run , effort, energy economic benefits. These bearings are generally seat shell, gaskets, bearing shafts, spindles, bushings, friction bearings composed of a variety Radial spherical, cylindrical roller, tapered roller bearings shift.
LNSERTED bearing variable speed drive bearing regardless of installation method, and its coupling with the requirements of both dimensions. Recommended use: inner bore and shaft with d Press H7/h6; in the ring with the drive pin holes do with the press H7/r6; outer shell with D and press H8/h7; drive and output shaft hole The clearance fit with the use of the gap volume of 0.2 ~ 0.5mm
