Abstract
The utility model discloses a rotating shuttle shaft. The rotating shuttle shaft comprises a rotating shuttle shaft body (1) which is provided with a bevel gear connecting shaft position (1.1), a rotating shuttle box body connecting shaft position (1.4) and a rotating shuttle connecting shaft position (1.8), wherein the bevel gear connecting shaft position (1.1) is provided with a holding screw supporting surface (1.2), the outer periphery of the rotating shuttle box body connecting shaft position (1.4) is surrounded with an oil groove (1.5); a retainer ring (1.7) is arranged between the rotating shuttle box body connecting shaft position (1.4) and the rotating shuttle connecting shaft position (1.8) and is integrally fixed with the rotating shuttle shaft body (1); the axes of the retainer ring (1.7) is on the same straight line with the axes of the rotating shuttle shaft body (1); and both ends of the retainer ring (1.7) are provided with tool withdrawal grooves. The rotating shuttle shaft has the advantages that the material is saved, the processing steps are simple, the processing is simple, the processing cost is low, and the precision is ensured.
Description
Technical field
The utility model relates to the sewing machine technique field, specifically is a kind of rotary shuttle shaft that is used for embroidery machine.
Background technology
Rotary shuttle shaft be in the computerized emboridering machine bevel gear to the transmission of power of rotating shuttle.General rotary shuttle shaft body is one a whole axle, needs when promptly using a back-up ring is installed in addition again, with holding screw both is linked together then, but also will adjust the two perpendicularity.There is following shortcoming in the rotary shuttle shaft of above prior art:
1, owing to need just to use after rotary shuttle shaft body, back-up ring, the holding screw three assembling when using, such three parts are processed respectively and are just caused waste of material, and procedure of processing complexity, processing charges are also high.
2, because rotary shuttle shaft body and back-up ring are friction tight, make the periphery of rotary shuttle shaft body and the inner headed face of back-up ring that good surface roughness will be arranged, just need carry out grinding machine processing, make processed complex, cost also improves.
3, because rotary shuttle shaft body and back-up ring are that certain perpendicularity requirement is arranged after the tight fit, after both process respectively so again close-fitting just be difficult to its precision of assurance together.
The utility model content
The technical problems to be solved in the utility model is that the rotary shuttle shaft that a kind of material is saved, procedure of processing is simple, processing is simple, processing charges is low, can guarantee its precision is provided.
The technical solution of the utility model is, a kind of rotary shuttle shaft with following structure is provided, comprise the rotary shuttle shaft body, the bevel gear connecting axle position that described rotary shuttle shaft body is provided with successively, rotating shuttle casing connecting axle position, rotating shuttle connecting axle position, described bevel gear connecting axle position is provided with holding screw bearing-surface radially, the outer circumference surface of described rotating shuttle casing connecting axle position is wound with the oil groove of spiral, is provided with escape between described bevel gear connecting axle position and the rotating shuttle casing connecting axle position; Also be provided with back-up ring between described rotating shuttle casing connecting axle position and the rotating shuttle connecting axle position, described back-up ring and rotary shuttle shaft body are solidified as a whole, the axis of the axis of described back-up ring and rotary shuttle shaft body is on same straight line, and the two ends of described back-up ring are equipped with escape.
After adopting above structure, the utility model compared with prior art has the following advantages:
1,, makes the material saving, procedure of processing is simple and processing charges is low because described back-up ring and rotary shuttle shaft body are solidified as a whole, and promptly back-up ring and rotary shuttle shaft body are that one is processed, and have saved by three original parts and have processed respectively.
2, because described back-up ring and rotary shuttle shaft body are solidified as a whole, need not the periphery of rotary shuttle shaft body and the inner headed face of back-up ring are carried out grinding machine processing, make processing simply, processing charges is low.
3, because described back-up ring and rotary shuttle shaft body are solidified as a whole, in processing, can guarantee perpendicularity between the two like this, can guarantee its precision.
Description of drawings
Accompanying drawing is the structural representation of rotary shuttle shaft of the present utility model.
As shown in the figure: 1, rotary shuttle shaft body, 1.1, bevel gear connecting axle position, 1.2, the holding screw bearing-surface, 1.3, escape, 1.4, rotating shuttle casing connecting axle position, 1.5, oil groove, 1.6, escape, 1.7, back-up ring, 1.8, rotating shuttle connecting axle position.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in the figure, rotary shuttle shaft of the present utility model, comprise rotary shuttle shaft body 1, described shuttle axle body 1 is provided with bevel gear connecting axle position 1.1, rotating shuttle casing connecting axle position 1.4, rotating shuttle connecting axle position 1.8 successively, the holding screw bearing-surface 1.2 that described bevel gear connecting axle position 1.1 is provided with radially, the outer circumference surface of described rotating shuttle casing connecting axle position 1.4 is wound with the oil groove 1.5 of spiral, is provided with escape 1.3 between described bevel gear connecting axle position 1.1 and the rotating shuttle casing connecting axle position 1.4; Also be provided with back-up ring 1.7 between described rotating shuttle casing connecting axle position 1.4 and the rotating shuttle connecting axle position 1.8, described back-up ring 1.7 is solidified as a whole with rotary shuttle shaft body 1, the axis of the axis of described back-up ring 1.7 and rotary shuttle shaft body 1 is on same straight line, and the two ends of described back-up ring 1.7 are equipped with escape 1.6.
