● Entwodiksyon

Stud tip woulèt traskonpoze de bag ekstèn ki gen miray epè-, arbr boulon, woulo zegwi ak asanble kaj, oswa seri eleman woule konplè. Se tras stud yo etenn, yo nan lòd yo evite konsantrasyon estrès, sifas ekstèn nan bag la epè -ranpa ekstèn roulo a gen fòm arc-. Dapre bezwen yo nan itilize, bag ekstèn lan kapab tou fèt nan yon sifas silendrik. Bag ekstèn lan gen de zo kòt entegral, ki gide axialman pa woulèt. Tèt la nan arbr boulon an ak laprès la-bann kenbe bò ekipe bay sipò axial pou bag la deyò nan woulèt yo. Lè roulo a koube deplase sou kous la plat oswa disk la Cam, estrès la entèn nan roulo a ogmante akòz deformation elastik nan bag la deyò. Koube woulo bi yo apwopriye pou pi lou chaj radial. Depi bag eksteryè a gide axialman pa woulèt, kote yo pote a kapab tou kenbe tèt ak pi lou chay axial, sa ki pèmèt operasyon relativman wo -vitès.

Stud tip tras woulèt bi yo lajman ki itilize nan machin twal, machin agrikòl, machin ak ekipman liy CONVEYOR, ray gid ekipman CNC, machin enprime ak lòt jaden.

● Seri kote yo pote

Kalite yo nanstud kalite tras woulètenkli seri KR, seri KR..-PP, seri KRE..-PP, seri KRV..{-PP, seri NUKR, seri NUKRE, seri PWKR..-2RS ak PWKRE..-2RS seri.

Seri KR: kote yo pote ak arbr boulon, roulo zegwi ak asanble kaj, li apwopriye pou chaj lou ak okazyon vitès mwayen.

Seri KRV: kote yo pote a se konplè zegwi a woulo estrikti, ki se apwopriye pou pi lou chaj ak pi ba vitès okazyon.

NUKR seri: kote yo pote a se plen konpleman silendrik roulo estrikti, ki se apwopriye pou pote chay patikilyèman wo, osi byen ke enpak chay axial.

◆ Commonly used steel for bearing rings

The commonly used steel for bearing rings is high carbon chromium bearing steel. At present, the standard of high carbon chromium bearing steel used is GB/T18524-2002 "High Carbon Chromium Bearing Steel". The basic steel grades are GCr4, GCr15, GCr15SiMn, GCr15SiMo and GCr18Mo. The commonly used ones are GCr15 and GCr15SiMn, and their properties are basically the same. But GCr15SiMn has better hardenability. High carbon chromium bearing steel can meet the requirements of general and some special-purpose bearings, with good wear resistance and contact fatigue resistance, ideal corrosion resistance, certain elasticity, toughness, and good processing performance. The price is cheaper. When manufacturing the chemical composition standard of the material used for bearing parts, the intrinsic quality of the bearing depends to a large extent on the metallurgical quality of the bearing steel - that is, the uniformity of the chemical composition, the content, type, size and distribution of non-metallic inclusions, carbonization material inhomogeneity and low magnification tissue. In addition, the heat treatment quality of bearing parts also plays a decisive role in the performance and life of the bearing. Most of the materials used to manufacture rolling elements are high-carbon chromium bearing steels. GCr15 is used to produce steel balls with a diameter of less than 45mm and rollers with a diameter of less than 22mm, otherwise GCr15SiMn is used.

◆ Detect the bearing noise

Anjeneral, itilizasyon enstriman yo pou detekte bri kote yo pote se pou kontwole valè maksimòm maksimòm, faktè krèt (oswa faktè krèt) ak konte batman kè nan Vibration kote yo pote. Konpayi RHP a fikse limit valè maksimòm pik la kòm 4 fwa valè rms, se sa ki, faktè krèt la se 4. Lè konte batman kè ki depase limit sa a se mwens pase 3 pousan konte batman kè valè pik ki depase rms. valè, portant la konsidere kòm soundless. Yon gwo kantite eksperyans yo te montre ke faktè krèt nòmal BEARINGS se 35, kote yo pote ak son nòmal se 610, li ka rive jwenn plis pase 10 nan ka grav. Anplis de sa, metòd tankou koyefisyan kurtosis, analiz spectre, analiz frekans anvlòp ak mezi entansite son yo ka itilize tou pou detekte ak analize pote son nòmal.

● Vire presizyon nan bag kote yo pote

Anplis egzijans tolerans dimansyon chak gwosè bag la, presizyon D 'nan bag kote yo pote, fòm li yo ak egzijans presizyon pozisyon yo jan sa a:

1. Lè roughing ferrule a, varyasyon lajè a (diferans paralèl) tout ferrule a ak kòt la pa ta dwe depase korespondan dimansyon tolerans ranje (ki gen ladan mou fanm k'ap pile fen figi). Si figi ki pa -referans yo itilize pou fini férule a, lè sa a li pa depase 1/2 nan tolerans dimansyon lajè li yo, ak paralelis nan Groove a nan figi pwent referans (Gove pandil) pa dwe depase. ranje a tolerans pozisyon Groove.

2. Erè dwat la nan dyamèt enteryè a ak jeneratris kous la pa dwe depase 1/4 nan tolerans dyamèt li yo.

3. Flatness nan figi pwent referans la pa dwe pi gran pase 1/4 nan alokasyon lajè a, figi a ki pa -referans pa dwe pi gran pase 1/2 nan tolerans lajè a, ak pozisyon ki pi ba a dwe. pa dwe mwens pase lajè minimòm ki espesifye nan teknoloji pwosesis la. Si inegalite nan figi a fen ak reyur rive an menm tan an, plat la ta dwe gen ladan reyur.
