[specific embodiment]
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
As shown in Fig. 1 to Fig. 3:
The invention process is listed as described a kind of novel sewing machine, include body 1, be provided with at least one group of above drive gear set in the described body 1, described drive gear set includes one and adopts formed in mould gear wheel and to adopt the pinion of machining (such as traditional cage chair formula board) cutting moulding, the gear wheel of every group of drive gear set is installed in respectively on the different turning cylinders with pinion, and intermeshing driving connects.Concrete structure can for: described drive gear set includes upper drive gear set 21 and lower drive gear set 22, described upper drive gear set 21 mainly is comprised of first gear 211 and the first pinion 212, described lower drive gear set 22 mainly is comprised of second largest gear 221 and the second pinion 222, described body 1 is provided with the first driving shaft 11, the second driving shaft 12 and the 3rd driving shaft 13, described the first driving shaft 11 is provided with first gear 211, one end of described the second driving shaft 12 is provided with the second pinion 212 that is connected with a joggle with first gear 211, the other end is provided with second largest gear 221, described the 3rd driving shaft 13 1 ends are provided with the second pinion 222 that is connected with a joggle with second largest gear 221, and the other end is connected with drive motors; And first gear 211 and second largest gear 221 by the superalloy dusty material by the die casting moulding, concrete steps comprise: at first, in order to meet the requirements such as environment, stressed load and service life in Sewing machines of first gear 211 and second largest gear 221, in independently developed spiral bevel gear design software, calculate optimal movement characteristic flute profile, and output pinion cutting board setup parameter and gear wheel mould flute profile 3D model, make gear wheel flute profile mould by the CAD/CAM technology; Then make first gear 211 and second largest gear 221; At last, carrying out final gear product by the spiral bevel gear design software output measurement point data of exploitation measures, error between comparison Theoretical Design and the finished product is adjusted process parameter or fine setting flute profile mould, thereby improves constantly the quality of the gear wheel of tool shape mould manufacturing.
