Description
技术领域technical field
本发明属于石油钻井设备技术领域,具体涉及一种位移补偿型整体式鼓形齿联轴器。The invention belongs to the technical field of oil drilling equipment, and particularly relates to a displacement compensation type integral drum-shaped tooth coupling.
背景技术Background technique
随着石油勘探装备开发的快速发展,石油钻机及核心配套装备开发的力度的增大,对机械设备传动轴系中应用最频繁的通用部件—联轴器的设计要求越来越高,联轴器主要有刚性联轴器和挠性联轴器两种类型。刚性联轴器不具有补偿被联接两轴轴线相对偏移的能力,也不具有缓冲减震性能。而挠性联轴器具有一定的补偿位移能力,补偿量可随型号不同而变化,一般满足该要求的联轴器有十字式万向联轴器和大转矩鼓形齿联轴器等。With the rapid development of oil exploration equipment development and the increasing development of oil drilling rigs and core supporting equipment, the design requirements for couplings, the most frequently used general components in mechanical equipment transmission shafting, are getting higher and higher. There are two main types of couplings: rigid couplings and flexible couplings. Rigid couplings do not have the ability to compensate for the relative offset of the axes of the two coupled shafts, nor do they have buffering and shock absorption properties. The flexible coupling has a certain ability to compensate for displacement, and the amount of compensation can vary with different models. Generally, the couplings that meet this requirement include cross-type universal couplings and high-torque drum tooth couplings.
作为一种改进,十字式联轴器的转矩可以达到允许使用范围,但承载冲击性能差,且这种联轴器允许两轴之间有较大的夹角,在轴运转时,夹角发生改变仍可正常传动,夹角过大时,传动效率会有显著的降低。且该类联轴器寿命短。As an improvement, the torque of the cross coupling can reach the allowable range, but the bearing impact performance is poor, and this coupling allows a large angle between the two shafts. When the shaft is running, the angle If the change occurs, the transmission can still be normal. When the included angle is too large, the transmission efficiency will be significantly reduced. And this type of coupling has a short life.
作为一种改进,鼓形齿式联轴器角向补偿大于直齿式联轴器,国内外均广泛采用鼓形齿式联轴器,但当前比较常用的鼓形齿式联轴器内齿齿套一般为两瓣式,通过法兰连接铰孔螺栓传递剪切应力,因此对铰孔螺栓的强度要求较高。同时,鼓形齿式联轴器安装的同轴度的精度,对减速机、动力端的运转、振动、噪音和使用寿命有着重要的影响,特别是对联轴器本身的使用寿命影响更大,所以在加工、安装过程中要求保证其加工、安装精度,两瓣式联轴器需要安装完成再进行配制铰制孔,对安装及加工能力要求较高。为了延长联轴器使用寿命,提高传动轴系工作性能,降低装配难度等,研究一种承载能力大、结构简单、径向尺寸小且安装难度低的整体式联轴器具有很重要的意义。综上来看,目前的联轴器存在对铰孔螺栓强度要求较高、安装以及现场加工要求高的问题。As an improvement, the angular compensation of the drum gear coupling is greater than that of the straight gear coupling. The drum gear coupling is widely used at home and abroad, but the inner gear of the drum gear coupling is currently more commonly used The tooth sleeve is generally two-lobed type, and the shear stress is transmitted through the flange connection of the reamed bolt, so the strength of the reamed bolt is required to be high. At the same time, the accuracy of the coaxiality of the drum gear coupling has an important influence on the operation, vibration, noise and service life of the reducer and power end, especially the service life of the coupling itself. In the process of processing and installation, it is required to ensure its processing and installation accuracy. The two-lobed coupling needs to be installed and then prepared with reamed holes, which requires high installation and processing capabilities. In order to prolong the service life of the coupling, improve the working performance of the transmission shaft, and reduce the difficulty of assembly, it is of great significance to study an integral coupling with large bearing capacity, simple structure, small radial size and low installation difficulty. To sum up, the current coupling has the problems of high requirements on the strength of reaming bolts, high requirements on installation and on-site processing.
