尼龍齒式對輪聯軸器使用壽命
ROD鼓形齒式聯軸器是Rokee獨立開發的核心技術傳動產品之一并且在國家建立和報備了企業技術標準，結合了日本，德國等先進國家的鼓型齒聯軸器標(biao)準(zhun)技術，優(you)化了(le)很(hen)多細部(bu)尺寸(cun)鏈，采(cai)用(yong)(yong)了(le)大壓力角齒(chi)形設計(ji)，軸孔采(cai)用(yong)(yong)短軸設計(ji)，縮小了(le)長徑(jing)比(bi)，結構更加緊湊(cou)，轉速性能優(you)異。相(xiang)近型號的螺栓(shuan)采(cai)用(yong)(yong)標(biao)準(zhun)統(tong)一(yi)化，零(ling)部(bu)件通用(yong)(yong)性好。
與國家標準齒式聯軸器相比能(neng)(neng)夠傳遞更(geng)大的(de)扭矩(ju)，質(zhi)量相對(dui)大幅度減輕，轉動慣量小，符合歐洲(zhou)防爆要(yao)求，各(ge)種綜合性能(neng)(neng)大大超前。為了更(geng)好的(de)傳動性能(neng)(neng)，我們強烈(lie)推(tui)薦您(nin)選(xuan)用。
鼓型齒式聯軸器是一種特別設計的先進齒式聯軸器，其外齒制成球面，球面的中心在齒輪的軸線上，齒側的間隙比一般產品稍大，鼓形齒聯軸器可以(yi)傳遞較(jiao)大的扭矩和允許較(jiao)大的角位移，性能優異(yi)且壽命更加長(chang)久。
As the gear type flexible coupling, it can be applied into various general drive sites. Due to the special hook face drum gear design, in the definitive deviation scope, it can effectively avoid the edge stress concentration at tooth meshing, so it has outstanding radial and angular centering capacity. Moreover, it can ensure long service life. ROD series drum gear coupling is one of Rokee’s core technical products. It has compact and reasonable structure, light weight, small hole-position fitting draw ratio, large pressure angle design, accurate centering and excellent speed performance. The bolt design has been standardized in series, the universality of parts is good and its service life far exceeds the one of domestic products.
The gear sleeve at both sides is in the structure of locating ring and uniform parts are used. In addition, the sealing is excellent and easy. Curved-tooth Gear Couplings are applied with larger pressure angle design. The product design is more reasonable and quality is reliable. The gear backlash is reasonable. All ROD series drum type gear couplings are designed in optimization, the structure is more compact and the proportion of hole diameter and length is more coordinated and reliable. Light weight and small rotational inertia. It’s made of high-quality alloy forged steel. It’s very applicable to the sites with anti-explosion requirements. The bolt size of adjacent models is the same and the installation is more convenient. Gear Coupling parts of same model can be exchanged for installation.
