The Research On Heavy Vehicle Wheel Reducer

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.
