Abstract
The utility model relates to an automobile transmission shaft, in particular to a diaphragm coupling. The diaphragm coupling comprises a shaft, and is characterized in that a front half shaft coupling and a rear half shaft coupling are arranged at the two ends of the shaft, the middle of the front half shaft coupling and the middle of the rear half shaft coupling are respectively provided with a cylinder protruding outwards, the front half shaft coupling and the rear half shaft coupling are provided with installation holes for installing diaphragms in a matched mode, and the diaphragms are installed between the front half shaft coupling and the rear half shaft coupling through bolts in a staggered mode. The diaphragm coupling of the structure has the advantages of being simple in structure, small in size, light in weight, capable of reducing shock, good in buffer effect and free of lubrication.
Description
Technical field
The utility model relates to a kind of truck drive shaft, specifically a kind of diaphragm coupling.
Technical background
Two axles (driving shaft and driven shaft) that coupling is used for connecting in different institutions make it common rotation with the mechanical parts of transmitting torque.Coupling cushions absorbing in addition, can the large axial displacement of compensate for slower, and radial displacement and the angular displacement of trace, elastic coupling flexible coupling is comprised of two halves, connects respectively with driving shaft and driven shaft.Be mainly used in forward and reverse variation many, start frequently in high speed shaft.
At existing coupling two ends, be provided with half shaft coupling, centre is provided with rubber body, and the coupling of this spline structure exists installs complexity, and the easy wear out failure of rubber body, is used inconvenient shortcoming.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned shortcoming, provides a kind of simple in structure, and volume is little, lightweight, damping, good buffer effect, non-lubricating diaphragm coupling.
The technical solution of the utility model is achieved in that a kind of diaphragm coupling, comprise axis body, it is characterized in that: described axis body two ends are provided with forward and backward half shaft coupling, in the middle of described forward and backward half shaft coupling, be provided with the cylindrical of outwardly convex, described forward and backward half shaft coupling is provided with and coordinates the mounting hole that diaphragm is installed, and described diaphragm is arranged between forward and backward half shaft coupling alternately by bolt.
Described diaphragm is Stainless Sheet Steel, and diaphragm is comprised of 5-20 sheet, and described diaphragm is six prismatics.
Further say: described forward and backward half shaft coupling is provided with 2-6 mounting hole.
Because diaphragm itself is very thin, so it is easy to bending when relative displacement load produces, therefore can bear the deviation up to 1.5 degree in use, in servo-system, produce lower bearing load simultaneously.
The beneficial effects of the utility model are: the diaphragm coupling of this spline structure has simple in structure, and volume is little, lightweight, damping, good buffer effect, non-lubricating advantage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, axis body 2, forward and backward half shaft coupling 3, cylindrical 4, diaphragm 5, bolt.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of diaphragm coupling, comprise axis body 1, it is characterized in that: described axis body 1 two ends are provided with forward and backward half shaft coupling 2, in the middle of described forward and backward half shaft coupling 2, be provided with cylindrical 3 of outwardly convex, described forward and backward half shaft coupling 2 is provided with and coordinates the mounting hole that diaphragm 4 is installed, and described diaphragm 4 is arranged between forward and backward half shaft coupling 2 alternately by bolt 5.
Described diaphragm 4 is Stainless Sheet Steel, and diaphragm 4 is comprised of 5-20 sheet, and described diaphragm 4 is six prismatics.
Further say: described forward and backward half shaft coupling 2 is provided with 2-6 mounting hole.
Because diaphragm 4 itself is very thin, so it is easy to bending when relative displacement load produces, therefore can bear the deviation up to 1.5 degree in use, in servo-system, produce lower bearing load simultaneously.
The diaphragm coupling of this spline structure has simple in structure, and volume is little, lightweight, damping, good buffer effect, non-lubricating advantage.
