【摘要】 轮边减速器是传动系中最后一级减速增扭装置,采用轮边减速器可满足在总传动比相同的条件下,使变速器、传动轴、主减速器、差速器、半轴等部件的载荷减少,尺寸变小以及使驱动桥获得较大的离地间隙等优点,它被广泛应用于载重货车、大型客车、越野汽车及其他一些大型工矿用车。因此对轮边减速器的研究,具有很重要的实际意义和企业实用性。在本论文研究中,主要开展了如下工作:首先介绍了轮边减速器的原理,并对行星式轮边减速器的特点、传动类型及传动装置进行了阐述与分析。其次根据轮边减速器的工作要求,进行了传动设计计算,确定其主要部件的参数并校核了齿轮的强度。然后为了减少轮边减速器在工作条件下的啮合误差,本文从轮齿啮合受力出发,结合齿轮修形理论,寻找到一种更切合实际工作需要的用以确定齿轮修形量大小的计算方法。最后进行计算机仿真。在SolidWorks中建立出中心轮的三维实体模型,将其导入到有限元分析软件ANSYS中进行分析,比较了理论设计的轮齿与修形设计后的轮齿在啮合受力下的应力云图,证明了轮齿修形设计是安全可行的。更多还原

【Abstract】 Wheel reducer is the last of deceleration and twist transmission device,it can be reducible for the load of the transmission, drive shaft, final drive, differential, axle , smaller their sizes and larger off-axle ground clearance, etc. It is widely used in load trucks, large buses, off-road vehicles and other large industrial and mining vehicles, therefore, it is very important and practical for us to research on the wheel reducer The below main work is carried out in this dissertation:First of all, introduce the principle of reducer, describ and analyze the planetary wheel reducer characteristics, transmission types and transmission devices.Secondary, design and calculate the parameters of its major components by its operational requirements and check the strength of the gear.Thirdly, In order to reduce wheel reducer gear in error under the conditions of work, this article is from the tooth contact force, combined with gear modification theory, to find a method to calculate the size of gear modification under a more practical work condition.At last, computer simulation, create the solid model of the centre wheel through the SolidWorks, import it into the finite element analysis software ANSYS and analyse the force of the gear under the action of meshing. Compare the stress of cloud about the theoretical design of the tooth and the tooth after the modification design. Prove that the gear tooth modifying the design is safe and feasible.更多还原
