Problems solved by technology

[0003] The purpose of the present invention is to provide a spline shaft used for the rotor-stator separation technology of the parallel hydraulic retarder, which overcomes the air loss force generated between the rotor and the stator when the existing retarder is not working, and avoids the air loss. Damage to the car caused unnecessary fuel consumption

Abstract

The invention relates to the field of mechanical design, and discloses a spline shaft for the rotor and stator separation technology of a parallel-connection hydrodynamic retarder. The spline shaft comprises a spline main shaft, a limiting ring and a rotor impeller limiting table. By means of structure optimization design, multiple sets of multi-step threads are formed at one end of the spline main shaft; by means of repeated test modification, the design parameters of the multi-step threads are optimized, the strength of a designed screw structure is high, transmission torque is large, and a rotor and a stator are close to each other when working and are easy to separate when not working. The reasonably-designed spline shaft is clear in structure, and all portions are clear in function; and structural design has certain flexible adjustment space, the fine adjustment equipment of equipment can be met, and machining and forming are easy.

Description

technical field [0001] The invention relates to the field of mechanical design, in particular to a spline shaft used for the rotor-stator separation technology of a parallel hydraulic retarder. Background technique [0002] Mechanical devices typically transmit torque through keyed or splined connections. There are two types of splines: rectangular splines and involute splines. When the transmission load is large and the centering accuracy is high, the involute spline connection should be used. When the involute spline connection is under load, there is a radial force on the teeth, which can act as an automatic centering, so that the force on each tooth is even, and because the tooth groove is shallow, the stress concentration at the root of the tooth is small, and the weakening of the shaft and the hub Small, so it has the characteristics of high strength and long life. It is widely used in aviation, aerospace, automobile, shipbuilding, engineering machinery, heavy machin...
