AI Technical Summary
Existing couplings are ineffective at buffering axial loads on the main shaft, resulting in large fluctuations in the load on the main bearing and causing severe damage.
It adopts an input connecting sleeve, an output connecting sleeve and a diaphragm structure. The diaphragms are stacked and separated by rubber gaskets. The axial deformation capacity of the diaphragms is used to reduce the axial external force damage to the spindle. The coaxiality is maintained by concentric cones and concentric cone holes, which improves the ease of disassembly and assembly and rotational balance.
It effectively reduces the damage to other connecting parts caused by the axial load of the spindle, improves the ease of disassembly and assembly, and provides a balanced counterweight during rotation, thus enhancing the axial protection function of the coupling.

TECHNICAL FIELD
[0001] The utility model belongs to lathe technical field relates to a coupling with axial protection function. BACKGROUND
[0002] When the lathe is in axial feeding operation such as drilling, the main shaft bears large fluctuant load, which obviously damages the transmission and support parts (such as bearing) of the main shaft. The existing couplings mostly set rubber parts between the two connecting halves to buffer, but the effect is not obvious. CONTENT OF UTILITY MODEL
[0003] The utility model aims at the above problems existing in the prior art, and provides a coupling with axial protection function, and the technical problem to be solved by the utility model is how to reduce the adverse effects of the axial load of the main shaft.
[0004] The utility model discloses a coupling with axial protection function, which is characterized by comprising an input connecting sleeve, an output connecting sleeve and a plurality of diaphragms.
[0005] Further, the adjacent diaphragms are separated by a rubber gasket.
[0006] The disc-shaped diaphragm has certain axial deformation capacity, so that the damage of the axial external force to other connecting parts of the main shaft is smaller. In order to improve the pre-tightening force of deformation, a plurality of diaphragms are arranged. In addition, in order to avoid the influence of the coaxiality under the axial stress state, a structure for driving the input connecting sleeve and the output connecting sleeve coaxial and correcting deviation under the action of the axial external force is arranged between the input connecting sleeve and the output connecting sleeve, that is, the concentric taper head and the concentric taper hole.
[0007] Compared with the existing rigid coupling, the coupling has more advantages in terms of convenience in disassembly and assembly. At the same time, since the diaphragm is located on the outside of the input coupling, it can provide certain balance weight when rotating. BRIEF DESCRIPTION OF DRAWINGS
