EPT 雙鏈齒輪 SINGLE DOUBLE SPROCKETS  

標準A型雙鏈齒輪為使用兩個單一鏈條而設計齒輪由碳鋼 ( SAE 1035 )及堅硬鋸齒製成,下列所述的最大承受直徑乃
基於一般操作情形使用標準鏈及捲住鏈之程序,真正的承受直徑應視使用一般機器設計情況而決定之,鏈之表面壓
力應視上列同樣情形下制止。

Standard A Type Single Double-Sprockets are designed for use
with two single strand chains. The sprockets are made of carbon
steel ( SAE 1035 ) and hardened teeth. The maximum bore diameters shown below are based on general operating conditions using standard keys and key tapping procedure. Actual bore diameter should be determined using common machine design considerations. Key surface pressure should be checked on the same basis as above.
