Abstract
The utility model discloses a screw thread flocking soft shaft, comprising a shaft core, a steel wire layer and flosses. At least one steel wire layer is arranged on the outer surface of the shaft core; each steel wire layer is formed by spirally winding a plurality of steel wires in parallel; and the outermost steel wire layer is formed by commonly spirally winding one or more than one floss. The screw thread flocking soft shaft provided by the utility model has a simple manufacturing process. With the adoption of the manufactured screw thread flocking soft shaft, the problems of easiness of friction and large noise due to the connection between a hammer square head of the soft shaft and a coupler square hole in an engine or an output device can be solved; the square head of the screw thread flocking soft shaft is matched with the square hole, and the flosses of the screw thread flocking soft shaft are convex, so that a gap between the square head of the soft shaft and the square hole is reduced; the noise is eliminated when the screw thread flocking soft shaft rotates at a high speed; and meanwhile, the service life of the screw thread flocking soft shaft is prolonged. The screw thread flocking soft shaft provided by the utility model has the advantages of simple structure, reasonable design, simple process and high automation.
Description
Technical field
The utility model relates to the machine power transmission field, relates in particular to a kind of spiral lamination Flocking flexible shaft.
Background technique
At present, in automobile or other machinery fields, usually adopt flexible axle to come transmitting torque; Existing flexible axle generally by a metallic cable or wire as the axle core, the multilayer steel wire is twined in the outside, every layer of steel wire by many steel wires side by side spiral twine and form; Its pliability is strong, and twisting strength is high, but being connected of coupling square hole has certain clearance in this flexible axle side of rammer square toes and motor or the output unit; Can friction or collision take place with square hole, cause the wearing and tearing between flexible axle square toes and the accessory square hole, shortened the working life of flexible axle greatly; And friction and vibration can produce very big noise, and the user is produced harmful effect.
The model utility content
In view of the defective that above-mentioned existing technology exists, the purpose of the utility model is to propose a kind of spiral lamination Flocking flexible shaft, is used for friction and the highstrung environment of noise, like the automatic seat of luxury car etc.
The purpose of the utility model will be achieved through following technological scheme:
A kind of spiral lamination Flocking flexible shaft; Comprise a core, steel wire floor and knitting wool, the outer surface of said axle core is provided with at least 1 layer steel wire floor; Said steel wire floor by many steel wires side by side spiral be entwined, outermost said steel wire floor is entwined by one or more knitting wool and the many common spirals of steel wire.
Preferably, above-mentioned spiral lamination Flocking flexible shaft, wherein: be wound with said knitting wool on the square toes outer surface at said spiral lamination Flocking flexible shaft two ends, said square toes are socketed in the square hole accessory that is mated.
Preferably, above-mentioned spiral lamination Flocking flexible shaft, wherein: said steel wire floor by 4～12 steel wires side by side spiral be entwined.
Preferably, above-mentioned spiral lamination Flocking flexible shaft, wherein: said knitting wool is woollen goods.
The utility model preparation process is simple; The spiral lamination Flocking flexible shaft for preparing has solved being connected to produce and being prone to friction and the big problem of noise of coupling square hole in the flexible axle side of rammer square toes and motor or the output unit: the square toes with the spiral lamination Flocking flexible shaft cooperate with square hole; Its knitting wool protrudes, and reduces the gap of flexible axle square toes and square hole, and when running up; Eliminate noise, prolonged the working life of flexible axle simultaneously.The utility model is simple in structure, and is reasonable in design, and technology is simple, and automaticity is high.
Following constipation closes embodiment's accompanying drawing, the embodiment of the utility model is done further to detail, so that the utility model technological scheme is easier to understand, grasp.
Description of drawings
Fig. 1 is the utility model embodiment's a sectional view.
Embodiment
Embodiment
A kind of spiral lamination Flocking flexible shaft of present embodiment; As shown in Figure 1; Comprise a core (not shown), steel wire floor 1 and knitting wool 2, the outer surface of axle core is provided with at least 1 layer steel wire floor 1; Steel wire floor 1 by many steel wires 3 side by side spiral be entwined, outermost steel wire floor 1 is entwined by a knitting wool 2 and many steel wire 3 common spirals.Be wound with knitting wool 2 on the square toes outer surface at spiral lamination Flocking flexible shaft two ends, square toes are socketed in the square hole accessory that is mated.
Further, steel wire floor 1 by 4～12 steel wires 3 side by side spiral be entwined.
Further, knitting wool 2 is woollen goods.
The preparation method of above-mentioned a kind of spiral lamination Flocking flexible shaft comprises the steps:
Step 1: get many steel wires 3, successively layering side by side spiral be wound in the outer surface of a core, form steel wire floor 1;
Step 2: when many steel wires 3 spirals of outermost steel wire floor 1 twine, be reserved with the groove that together waits width;
Step 3: in groove, implant the knitting wool 2 of one or more winding, the width of groove is consistent with the width of the knitting wool of implantation 2, through high temperature melting technology, clings flexible axle after making knitting wool 2 thawings, obtains spiral lamination Flocking flexible shaft semi-finished product;
Step 4: with the rammer side, the half-finished two ends of spiral lamination Flocking flexible shaft that step 3 obtains, keep the knitting wool 2 at square toes place, and remove the burr that rammer side produces, process the spiral lamination Flocking flexible shaft.
Present embodiment preparation process is simple; The spiral lamination Flocking flexible shaft for preparing has solved being connected to produce and being prone to friction and the big problem of noise of coupling square hole in the flexible axle side of rammer square toes and motor or the output unit: the square toes with the spiral lamination Flocking flexible shaft cooperate with square hole; Its knitting wool 2 protrudes, and reduces the gap of flexible axle square toes and square hole, and when running up; Eliminate noise, prolonged the working life of flexible axle simultaneously.
The utility model still has numerous embodiments, and all employing equivalents or equivalent transformation and all technological schemes of forming all drop within the protection domain of the utility model.
