【摘要】：游梁式抽油机仍然是当今各油田采油设备的主要机型,其传动装置普遍采用带传动,鉴于带传动系统中存在的弹性滑动、打滑和丢转等现象,尤其是遇到雨雪天气还会出现失稳、失效、加快磨损缩短传动带的使用寿命,甚至会烧带而被迫停机,本文针对抽油机带传动系统的带与带轮结构进行了重新设计,完成了抽油机防滑改造,设计了联组齿形窄V带传动,有效解决了带传动中的打滑、丢转和频繁更换带问题,从而提高带传动的效率,传动带的使用寿命得到大幅度的提高,减小了现场工人的劳动强度,提高了采油生产效率,节约了电能。 论文以带传动的工作原理入手,通过深入分析研究摩擦型带传动的摩擦机理以及啮合型带传动的啮合机理,摩擦型传动带弹性滑动发生的过程与原理,对同步带的运行受载进行了详细分析,得出带齿受载变形理论,取得了带传动理论研究的突破性进展,以此为基础,研究分析了联组齿形窄V带传动的工作原理,为后续设计工作起到了指导作用。通过理论分析,指出摩擦传动与啮合传动能够同时存在于同一种带传动形式中,能够同时工作而互不发生干涉,证明了对抽油机带传动系统的改进设计是合理的。 把摩擦传动与啮合传动结合起来,进行带与带轮的结构设计,带齿与轮齿的齿形设计与齿廓参数选择。建立三维几何模型,对带齿所受应力应变进行有限元分析,结果显示带齿的受载变形与应力分布情况与理论分析一致,进而指导带齿与轮齿齿廓参数的优化设计工作,以选择更合理的带与带轮尺寸参数,延长使用寿命。 在带传动实验台上,测试联组齿形窄V带传动的传动特性与弹性滑动率,实验证明摩擦传动与啮合传动能够同时传递运动与动力,同时进行了同等实验条件下普通联组带窄V带的传动特性实验,通过实验结果的分析与对比,充分显示了重新改进设计后带传动的优越性,消除了打滑现象,有效解决了由弹性滑动引起的丢转问题,具有滑动率低、传动效率高、受载均匀合理、对中心距不敏感等优点。最后,还进行了现场安装应用实验,连续采集实验数据显示联组齿形窄V带传动取得了良好的效果,提高了传动带的使用寿命和采油厂的采油生产效率。
[Abstract]:Beam pumping unit is still the main type of oil production equipment in various oilfields today. Belt drive is widely used in its transmission device. In view of the phenomena of elastic sliding, slippage and loss of rotation in the belt drive system, Especially in the case of rain and snow, there will be instability, failure, accelerated wear, shorten the service life of the belt, and even will burn the belt and be forced to stop. In this paper, the belt and pulley structure of the belt drive system of the pumping unit are redesigned, and the structure of the belt and pulley is redesigned. The anti-skid revamping of the pumping unit is completed, and the narrow V-belt drive is designed, which effectively solves the problems of skidding, losing and frequently changing the belt in the belt drive, so as to improve the efficiency of the belt transmission and greatly improve the service life of the belt. It reduces the labor intensity of the workers in the field, improves the productivity of oil production, and saves the electric energy. Based on the working principle of belt drive, the friction mechanism of friction belt drive, meshing mechanism of meshing belt drive, and the process and principle of elastic sliding of friction belt drive are studied through in-depth analysis of the mechanism of friction belt drive and meshing mechanism of meshing belt drive. The operating load of synchronous belt is analyzed in detail, the deformation theory of belt tooth is obtained, and the breakthrough development of belt transmission theory is obtained. On the basis of this, the working principle of the combined tooth-shaped narrow V-belt drive is studied and analyzed. It plays a guiding role in the follow-up design work. Through theoretical analysis, it is pointed out that friction drive and meshing drive can exist in the same type of belt drive at the same time and can work at the same time without interference. It is proved that the improved design of belt drive system for pumping units is reasonable. The structure design of belt and pulley, tooth profile design and tooth profile parameter selection of belt and gear teeth are carried out by combining friction transmission with meshing drive. The three-dimensional geometric model is established and the finite element analysis of the stress and strain of the belt tooth is carried out. The results show that the load deformation and stress distribution of the belt tooth are consistent with the theoretical analysis, thus guiding the optimization design of the tooth profile parameters of the belt tooth and the gear tooth. To select more reasonable belt and pulley size parameters, extended service life. On the experimental platform of belt transmission, the transmission characteristics and elastic slip rate of the combined tooth-shaped narrow V-belt drive are tested. The experiment proves that the friction drive and the meshing drive can simultaneously transfer the motion and the power. At the same time, under the same experimental conditions, the experiment of the transmission characteristics of the common band narrow V-belt is carried out. Through the analysis and comparison of the experimental results, the advantages of the redesigned belt drive are fully demonstrated, and the sliding phenomenon is eliminated. The problem of loss of rotation caused by elastic sliding is solved effectively. It has the advantages of low slip rate, high transmission efficiency, uniform and reasonable load, and insensitivity to center distance. Finally, the field installation and application experiment is carried out. The continuous collection of experimental data shows that the combined gear-shaped narrow V-belt drive has achieved good results, and the service life of the drive belt and the production efficiency of the oil production plant have been improved.
