How to do the clutch release bearing failure

How to do the clutch release bearing failure

 (1) free travel is too small or the number of times by the excessive load. Upon request, the general clutch lever clearance between the High speed Spindle and the separation of 2.5mm more appropriate to reflect on the clutch pedal free travel for 30 ~ 40mm, free travel is too small or no free travel, will make the separation lever and separation bearing in a normally engaged state. According to the principle of fatigue damage, bearing work longer, more severe damage; the more times by the carrier, the more easily separated bearing fatigue damage. And the longer working hours, the higher the temperature of the bearing, the easier burning, reduce the release bearing life.

 (2) whether the separation was smooth adjustment lever and release fork is deformed, release bearing the return spring is good, but also has a great influence on the release bearing damage. Separated uneven, release fork deformation, release bearing spring does not return, will result in the clutch release bearing against the work, so that is always in the work release bearing state, the temperature rising, burn easily release bearing, release bearing lower life.

ZYS clutch bearing within this life , should occur initial fatigue damage

Rolling of life in revolutions ( or hours to work under a certain speed ) , definition: bearings within this life , should occur initial fatigue damage ( spalling or defect ) any bearing on their laps or rolling . However, both in laboratory tests or in actual use , can be clearly seen , the same appearance under the same operating conditions of the bearing , the actual life different. There are also a number of different definitions of deep groove ball bearings , " life " , one of which the so-called " working life ", which represents the actual life of a bearing damage can be achieved before by wear, damage is usually not caused by the fatigue , but is caused by wear and tear , corrosion, seal damage and other reasons .
By mechanical means of the metal surface layer is plastically deformed to form a high hardness super-precision bearing and high strength hardened layer , the surface strengthening method called surface deformation strengthening , also called hardening . Including blasting , sandblasting, cold extrusion, rolling, cold- milled and shock , explosion shock processing and so on. Features deep groove ball bearings of these methods are: strengthening layer increased dislocation density , sub- crystal structure refinement, making it the hardness and strength increased , the surface roughness value decreases, the surface can significantly improve the fatigue strength of parts and reduce fatigue notch sensitivity. This enhanced process is simple , the effect is significant , there is no clear Wind turbine bearing  between the hardened layer and the substrate , the structure of a coherent , easy to fall off in use. Most of the methods which have been applied in the bearing industry : rolling surface is applied to strengthen the impact of these methods , precision ferrule RCC has become a new and enhanced processing methods .

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

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
