Description
技术领域technical field
本发明涉及传动装置，具体是一种竹筏动力传动装置。The invention relates to a transmission device, in particular to a bamboo raft power transmission device.
背景技术Background technique
现有的竹筏动力传动装置，包括电机、联轴器、传动轴、传动杆、变速箱和浆叶轮；传动轴的轴承设在两端，当传动轴高速旋转时，传动轴因为离心力易变形，与传动杆内壁接触，摩擦阻力大，增加传动阻力，能量损失严重。用发动机做动力尚可，但发动机噪音大，油污污染河面严重，如果用直流电源加电机做动力时，无法产生足够的推动力。The existing bamboo raft power transmission device includes a motor, a shaft coupling, a transmission shaft, a transmission rod, a gearbox and a paddle wheel; the bearings of the transmission shaft are arranged at both ends, and when the transmission shaft rotates at a high speed, the transmission shaft is easily deformed due to centrifugal force , in contact with the inner wall of the transmission rod, the frictional resistance is large, the transmission resistance is increased, and the energy loss is serious. It is acceptable to use the engine as power, but the engine noise is loud, and the oil pollutes the river surface seriously. If a DC power supply and a motor are used as power, it will not be able to produce enough driving force.
另外，现有竹筏动力传动装置的齿轮箱里面一般是注满粘稠的黄油做为润滑剂，没有做密封处理，容易泄漏污染河面，同时黄油的润滑效果不如液态齿轮油，也会造成部分能量损失。In addition, the gear box of the existing bamboo raft power transmission device is generally filled with viscous butter as a lubricant, without sealing treatment, it is easy to leak and pollute the river surface, and the lubricating effect of butter is not as good as that of liquid gear oil, which will also cause some energy loss.
发明内容Contents of the invention
本发明的目的是针对现有技术的不足，而提供一种能减小传动轴摩擦的竹筏动力传动装置。The object of the present invention is to provide a bamboo raft power transmission device capable of reducing the friction of the transmission shaft in view of the deficiencies in the prior art.
实现本发明目的的技术方案是：The technical scheme that realizes the object of the present invention is:
一种竹筏动力传动装置，包括电机、联轴器、传动杆、传动轴、变速箱和浆叶轮、电机安装在竹筏尾部；所述变速箱内设有啮合连接的第一圆锥齿轮和第二圆锥齿轮，第二圆锥齿轮的前端连接传动杆，传动杆的前端、中部、后端分别设有轴承；A bamboo raft power transmission device, including a motor, a shaft coupling, a transmission rod, a transmission shaft, a gearbox and a paddle wheel, and the motor is installed at the tail of the bamboo raft; the gearbox is provided with a meshing first conical gear and a second Two bevel gears, the front end of the second bevel gear is connected to the transmission rod, and the front end, middle part and rear end of the transmission rod are respectively provided with bearings;
传动轴配装在传动杆的轴承内圈，并与第二圆锥齿轮连接；The transmission shaft is fitted on the bearing inner ring of the transmission rod and connected with the second bevel gear;
电机的输出轴通过联轴器与传动轴的另一端连接；The output shaft of the motor is connected with the other end of the drive shaft through a coupling;
浆叶轮的旋转轴设在变速箱内，浆叶轮的旋转轴与第一圆锥齿轮连接。The rotation shaft of the paddle wheel is arranged in the gearbox, and the rotation shaft of the paddle wheel is connected with the first bevel gear.
所述第一圆锥齿轮大于第二圆锥齿轮，构成扇形齿轮减速器。The first bevel gear is larger than the second bevel gear, forming a sector gear reducer.
所述传动杆的中部轴承外圈与传动杆内壁配装有橡胶圈。The outer ring of the middle bearing of the transmission rod and the inner wall of the transmission rod are equipped with a rubber ring.
所述浆叶轮的旋转轴上设有油封与变速箱的连接部密封。The rotating shaft of the paddle wheel is provided with an oil seal to seal the connecting portion of the gearbox.
所述传动轴与联轴器的连接端口设有油封密封。The connection port between the transmission shaft and the coupling is provided with an oil seal.
所述变速箱的连接端口设有O型圈和端口盖密封。The connecting port of the gearbox is sealed with an O-ring and a port cover.
众所周知，长轴连接原则上是在其两端设置轴承。如果要在长轴上设置三个轴承，那么这三个轴承的同轴度精度要求极高，加工成本高。本发明传动装置在传动杆的中部增加了一个轴承，轴承外圈与传动杆内壁之间装有橡胶圈，该橡胶圈既可以固定传轴承，又因为橡胶可以变形，这样中部轴承位，即使加工精度不高，也可以保证同心度，这是本传动装置的创新点之一。As we all know, the long shaft connection is in principle provided with bearings at both ends. If three bearings are to be arranged on the long axis, the coaxiality precision of these three bearings is required to be extremely high, and the processing cost is high. The transmission device of the present invention adds a bearing in the middle of the transmission rod, and a rubber ring is installed between the outer ring of the bearing and the inner wall of the transmission rod. The precision is not high, and the concentricity can also be guaranteed, which is one of the innovative points of this transmission device.
另外，现有的齿轮箱里面一般是注满粘稠的黄油做防水，未做防水处理。本发明传动装置在前面加了一个油封，这样齿轮箱里面可以装液态齿轮油，相对阻力小，这也是本传动装置的创新点。In addition, the inside of the existing gearbox is generally filled with thick butter for waterproofing, without waterproofing treatment. The transmission device of the present invention adds an oil seal at the front, so that the gear box can be filled with liquid gear oil, and the relative resistance is small, which is also an innovative point of the transmission device.
在竹筏上安装本发明动力传动装置，启动电机，电机带动传动轴在三个轴承中旋转，不易变形，传动轴不再与传动杆内壁产生接触摩擦，减少传动过程中的阻力，另外与传动轴连接的第二圆锥齿轮小于桨叶轮上的第一圆锥齿轮，形成减速比，可增大浆叶轮的输出转矩和输出功率，同时又改变桨叶轮与传动轴的角度，使桨叶轮的轴线与水平面平行，从而达到最大有效推力，即节约电能又加快竹筏航行速度，增加航行里程。Install the power transmission device of the present invention on the bamboo raft, start the motor, and the motor drives the transmission shaft to rotate in three bearings, which is not easily deformed, and the transmission shaft no longer produces contact friction with the transmission rod inner wall, reducing the resistance in the transmission process. The second bevel gear connected to the shaft is smaller than the first bevel gear on the paddle wheel, forming a reduction ratio, which can increase the output torque and output power of the paddle wheel, and at the same time change the angle between the paddle wheel and the transmission shaft, so that the axis of the paddle wheel Parallel to the horizontal plane, so as to achieve the maximum effective thrust, which saves electric energy and speeds up the sailing speed of the bamboo raft, increasing the sailing mileage.
