設(shè)計(jì)規(guī)范:
■內(nèi)外部均采用的不銹鋼緊固件,具有良好的長期抗腐蝕能力
■高質(zhì)量的軸承,密封性好且摩擦系數(shù)低、使用壽命長,適用溫度。
■組合式預(yù)負(fù)荷彈簧座 ,具有特殊鍍層的彈簧適用于各種場合,、更抗腐蝕。
■齒條和活塞上的復(fù)合軸承以及導(dǎo)向環(huán):可確保操作、低摩擦及長壽命,并可有效防止輸出軸斷裂。
■采用雙活塞齒輪齒條的結(jié)構(gòu)設(shè)計(jì):具有結(jié)構(gòu)緊湊、使用壽命長、動(dòng)作迅速等優(yōu)點(diǎn)。安裝位置對稱的設(shè)計(jì),可通過簡單的活塞對調(diào)方式來簡易地改變轉(zhuǎn)向。
Design Specifications:
■Stainless steel fasteners used both inside and outside have good long-term corrosion resistance
■High-quality bearings, good sealing, low friction coefficient, long service life, and applicable temperature.
■Combined preload spring seat, the spring with special coating is suitable for various occasions, and is more resistant to corrosion.
■Composite bearing and guide ring on the rack and piston: ensure operation, low friction and long life, and can effectively prevent the output shaft from breaking.
■Using the structure design of double-piston rack and pinion: it has the advantages of compact structure, long service life and quick action. The symmetrical design of the installation position can easily change the steering by a simple piston swap.
