The tapered roller bearings nsk are all soaked tank

Tapered roller bearings have tapered inner and outer ring raceways , tapered rollers are arranged between the two. All conical surface projection lines are a little get together with the ZYS wind turbine bearing  axis . This design makes tapered roller bearings particularly suitable for combined ( radial and axial ) loads. Most of axial load bearing capacity is determined by the contact angle α ; greater the angle α , the higher the axial load capacity . Angle size calculation factor e ; e value , the greater the contact angle , bearing axial load greater applicability . Wanguan Metal Machine Network Xiaobian to introduce
Bearing Maintenance : Bearing cleaned up : Assembly under nsk tapered roller bearings overhaul , the first recorded appearance of bearing , confirmed the residual amount of lubricant , lubricant used after sampling review , wash bearings.
The tapered roller bearings nsk are all soaked tank , oil -filled bearings from the machine brought up , and then flows back to the oil tank should be slightly less than the minimum Gulu body place. Such a measure normally smooth application of grease -20 ~ 120 ℃, while above 150 ℃ cryogenic applications are being , arise from basic oil boiling too fast, run off and serious scenes, greatly extending the life expectancy ZYS Angular contact ball bearing  applications . As cleanse agent, generally use gasoline, kerosene . However, because the application of the basic mineral oil , so that is the kind of smooth fat being played together on a number of biochemical markers buckle rust and rust function outside . Mid-sized non- break ball bearings , the inner ring with one hand support level , filled outer confirm whether smoothly. Because the choice of the kind of smooth fat fiber delicate, melancholy light filter to waste lithium thickener , application of mineral oil as the basic oil, very light foot outside the high-end bearing is difficult to know the value of increased vibration request . In order to determine the assembly up of tapered roller bearings nsk whether you can use to clean bearings after being reviewed. Oil can be taken away due to repeated heat determine the bearing cool down , so law applies to high speed bearing components. Law suitable for high-speed, high-temperature lubrication of the bearing components. Wanguan Metal Machine Network Xiaobian to introduce

The main task of bearing failure analysis is based on a lot of background material

metallurgical quality ntn bearing material was the main factor in the impact of early bearing failure . With metallurgical technology ( such as bearing steel vacuum degassing, etc. ) progress, raw material quality is improved. Raw material quality factors in ZYS wind turbine bearing cylindrical roller bearing failure analysis in the proportion has decreased significantly , but it is still one of the main factors bearing failure . Appropriateness of the selection is still bearing failure analysis must be considered.
The main task of bearing failure analysis is based on a lot of background material , analysis of data ZYS Precision Bearings and failure modes , identify the main factors causing ntn bearing failure , so that puts forward improvements to extend bearing service period to avoid cylindrical roller bearings sudden occurrence of early failure .
Second is probably too big a load ( preload too big ) . Speed ​​is too large. Clearance is too small . Water or other foreign matter intrusion. If the above two cases is that the shaft is not so bad precision of the bearing housing , shaft deflection great. See here, I think everyone wants to know the solution of it, first of all, to study the lubricant and lubrication method , the election of the cylindrical roller bearing lubricant , and its amount , but also to rectify ntn bearing selection . Research to tie , bearing clearance and preload , and improved sealing device . Check the accuracy of the shaft and the bearing housing .

Drum Roller Bearings heat treatment

Fundamental types of drum-type roller bearings either using window glass fiber reinforced polyamide (nylon) 66 stick frame (suffix T), also can be machined solid brass stick rack (suffix MB). Glass fiber reinforced polyamide 66 insist on lower shelf stable up to temperatures form 120 ℃. If the bearing oil is smooth, then smooth oil additive ball bearing will reduce the use of stick frame life of aging oil at low temperatures also have an adverse effect on the stick rack; therefore necessary to monitor the oil change.
Drum Roller machine tool spindle Bearings heat treatment
After heat treatment of the FAG drum roller bearings, tasks temperatures up to 150 ℃, the temperature of the outside diameter of 120mm beyond the task of bearing up to 200 ℃, the size is still able to adhere firmly. If the bearing polyamide stick frame, the frame data necessary to pay attention to adhere to temperature constraints.
