Application demand price clasticity instructs the market behavior 應(yīng)用需求價格彈性指導(dǎo)市場行為
High - clasticity , good wear - resistance , oil - resistance . small circle - resilience difference , high metal core stability 耐油、彈性好、耐磨性優(yōu)良,圓跳動公差小,金屬芯平衡度高。
As shown in the figure left , the inner ring of the self - contained bearing is hardened in the race - way and surroundings part where hardening is necessary , the area of set screw hole of the inner ring has been templed by high temperature after hardened , it has higher toughness and impact clasticity 如左圖所示,內(nèi)圈溝道及其周圍需要淬硬的部分已經(jīng)過正常淬火,裝配緊定鏍釘?shù)膬?nèi)圈伸長端則經(jīng)過高溫局部回火而保持韌性及抗沖擊性。
