Abstract

The invention discloses a motor clutching flywheel of an industrial sewing machine. The key point of the technical scheme is that: the flywheel comprises a flywheel flat plate manufactured by stamping, wherein a coupling part which is bulged backwards is arranged on the flywheel flat plate; the rear side of the flywheel flat plate is fixedly connected with a flywheel ring; and an impeller which is connected with the flywheel flat plate in a tight attaching way is arranged in the flywheel ring. In order to overcome the defects in the prior art, the motor clutching flywheel of the industrial sewing machine, which has a simple structure and low manufacturing cost and is stably operated, is provided; and the invention also provides a manufacturing method of the flywheel.

Description

【Technical field】 [0001] The invention relates to an industrial sewing machine, more specifically to a motor clutch flywheel of an industrial sewing machine, and also provides a manufacturing method of the flywheel. 【Background technique】 [0002] At present, the flywheels of the clutch motors of industrial sewing machine motors are all made of cast iron. The disadvantages are: the cast flywheel has a lot of trachoma and pores; the hardness of the material is unstable and difficult to process, and the cost is high; and due to the trachoma and pores, the quality of the flywheel circumference is uneven, resulting in uneven balance, which makes the motor vibrate greatly during operation. 【Content of invention】 [0003] The object of the invention is to overcome the deficiencies of the prior art, and provide a clutch flywheel for motors of industrial sewing machines with simple structure, low manufacturing cost and stable operation. The invention also provides a manufacturing ...
