Abstract
The utility model discloses a coupler of a direct-driven type sewing machine, which comprises a step-shaped bearing bush, wherein a spring leaf assembly is arranged at the end surface of the large end of the bearing bush, a shaft adapter is arranged inside the small end of the bearing bush, the large end of the bearing bush is connected with a main shaft, and the shaft adapter is connected with the output shaft of a motor; and a bearing is sleeved at the small end of the bearing bush. According to the utility model, the spring leaf assembly with elasticity is arranged at the connection end of the main shaft, and clearance is reserved between the spring leaf assembly and the bearing bush, so that the inertia force in the start-up or stopping process can be effectively consumed, and the inertia influence is reduced.
Description
Technical field
The utility model relates to a kind of Sewing machines, is specifically related to a kind of shaft coupling of direct drive sewing machine.
Background technology
Realize being connected through shaft coupling between the direct driving motor 10 of direct drive sewing machine and the main shaft 20.
Be illustrated in figure 1 as the shaft coupling mode of prior art, adopt a rigidity axle sleeve 30 as shaft coupling, the output shaft of motor 10 and main shaft 20 are inserted by two ends respectively, are screwed again.The shortcoming of this shaft coupling is not have buffering effect, and is influential to the life-span of part.
Be illustrated in figure 2 as the another kind of shaft coupling mode of prior art, the shaft coupling 31 that is adopted comprises motor union end 11, main shaft union end 21, is provided with the rubber lining ring that is used to cushion between motor union end 11 and the main shaft union end 21.It is bigger that the shortcoming of this shaft coupling is that the life-span of shaft coupling is influenced by material, and have certain error space for the power that motor transmitted.
Summary of the invention
The utility model technical problem to be solved provides a kind of shaft coupling of direct drive sewing machine, and it can prolong the service life of motor and associated components.
For solving the problems of the technologies described above, the technical solution of the shaft coupling of the utility model direct drive sewing machine is:
Comprise the bearing insert that is step-like, the big end end face of bearing insert is provided with spring lamination, and the small end inboard of bearing insert is provided with shaft coupling; The big end of bearing insert connects main shaft, and shaft coupling connects the output shaft of motor; Be arranged with bearing on the small end of said bearing insert.
Achieve a fixed connection through second holding screw between said bearing insert and the main shaft; Achieve a fixed connection through first holding screw between the output shaft of said shaft coupling and motor.
Said spring lamination is fixedly connected with bearing insert through hold-down screw.
Be provided with packing ring between the end face of said spring lamination and bearing insert, make between spring lamination and the bearing insert and form the gap.
It between said bearing and the bearing insert interference fits.
Said spring lamination comprises two flat spring steel discs, and two flat spring steel discs are fixedly connected through attachment pegs.
The technique effect that the utility model can reach is:
The utility model is provided with the flexible spring lamination of tool at the link with main shaft, and between spring lamination and bearing insert, is provided with the gap, can consume the inertia force in the process of starting or stoping effectively, reduces the influence of inertia.
The utlity model has certain cushioning effect, can prolong the service life of motor and associated components.
The utility model is that " half steel property " connects, and not only the life-span is longer, and more accurate as the shaft coupling of intermediate medium than rubber to the transmission of power.
