Heavy transport vehicles the designed of universal coupling
Abstract
Mechanical transmission of universal coupling is a core component，In the power transmission plays a vital role.This design task is to design a heavy load for the universal coupling.This design uses a cross-axis transmission，The transmission is a universal feature：First, the connection and link to reduce，Reduce the failure rate，More reliable work，Extended service life，Also easy to maintain Also less wear and noise；，Second, a greater load bearing capacity in case of Stability of power transmission，And performance in a variety of complex very good condition.
In this paper, the working principle of universal coupling general analysis, and various design parameters of universal joints whether the use of strength of a more detailed design calculations. By analyzing several different universal coupling, the decision to adopt universal coupling cross shaft design type. Cross shaft universal coupling introduced the motion characteristics, as well as for the use of the common problems occurring in the remedy. Combined with car design, car theory, knowledge of mechanical design, calculation, or use the associated universal gear design parameters and demonstrate the rationality.Its function is :Achieve the transmission output shaft and drive axle input shaft relative position of constantly changing power transmission cases.
