本文根据国家标准“石油钻机型式与基本参数(GB1806-79)”的规定,阐述了钻机并车箱链条传动的设计原理,推荐了并车箱链条传动的主要设计参数(节距、齿数、排数、中心距),讨论了采用变距器传动时,并车链条的传递功率,指出了如何根据链条的“帐篷”曲线确定并车链条的攻关方向。
In this paper, according to the national standard “Model and Basic Parameters of Oil Drilling Rig (GB1806-79)”, the design principle of the drilling rig and the transmission of the car box chain is expounded. The main design parameters (pitch, number of teeth, Center distance). The transmission power of the car chain and the transmission power of the car chain are discussed when using the variator drive, and the direction of the key chain of the car chain is determined according to the “tent” curve of the chain.
