Description
Technical field
The utility model relates to a kind of nonstandard gear axle, and more particularly, it relates to a kind of self-locking gear shaft.
Background technique
Gear and axle are made one and are then claimed gear shaft, sometimes after shaft diameter design is determined, but the gear on axle is because to install or the requirement of the factor such as velocity ratio causes the number of teeth less and gear diameter is also less, if at this moment gear and axle not to be made one, then need to connect with key, the very thin thickness between the tooth root portion of such gear and keyway can not meet requirement of strength.If make one, do not have such problem, but too increase cost simultaneously, if gear tooth damages, need to change whole gear shaft.
Ordinary gear and axle assemble to utilize key to be connected and realize circumference and fixedly carry out transmitting torque, and axial restraint generally makes gear one end face be close to step, another side utilize axle sleeve or nut fixedly make whole gear axis and circumference all fixing, and this means of fixation is installed complicated, dismounting is inconvenient, application number be 201310639567.9 Chinese patent disclose one and automatically lock gear shaft, it relies on spring key to withstand by the structure arranging a similar button, and that gear plays axially with circumference is dual fixing, without the need to adding fixed axle sleeve or nut retaining element at the other end of gear, but there is gear one end and still must only be the reduction of the fixing of the gear the other end near step, the processing of axle still needs car to go out this step, secondly because the existence of this step has fixed the position of gear.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of self-locking gear shaft, and the manufacturing procedure of axle is few, and without the need near step, the setting position of gear does not freely retrain, and convenient disassembly is convenient to change.
For achieving the above object, the utility model provides following technological scheme:
A kind of self-locking gear shaft, comprise axle and gear, the circumferencial direction of described axle is provided with opening slot, the first elastic element is provided with bottom described opening slot, described first elastic element is connected to recessed piece, and described recessed piece of slippage is connected to opening slot, and the endoporus of described gear is provided with draw-in groove, described draw-in groove is position between gear both ends of the surface, described draw-in groove and recessed piece of clamping.
Pass through technique scheme, what utilize the first elastic element and recessed piece is combined through the draw-in groove snapping fit onto and be opened in the middle of bore, achieve gear shaft to circumference while fix, decrease the manufacturing procedure of whole axle, save time, because gear without the need to arranging axial restraint part on axle, the position that gear is arranged is more free, because precision during without the need to assembling near the shaft shoulder improves.
As preferably, slideway is provided with in described gear, described slideway is communicated with draw-in groove, be provided with slide block in described slideway, the end face of described slideway is provided with the second elastic element, and described second elastic element is connected to slide block, described slide block is connected with push rod, described gear is provided with push rod slideway, and described push rod slideway is communicated in draw-in groove, slideway and be communicated in the external world, and described push rod slippage is connected to push rod slideway.
By technique scheme, realize the dismounting of gear, utilize the slippage of promotion push rod band movable slider to extrude recessed piece that is located on axle, the direction when push rod abuts to axial plane firmly along axle; Pull-out gear, convenient disassembly, simple to operate.
As preferably, described push rod leads to extraneous one end and is provided with projection.
By technique scheme, utilize the projection people arranged can pull out gear easily, as the effect of a force bearing point when dismantling.
As preferably, the edge axle of described recessed piece be axially arranged with inclined-plane.
By technique scheme, facilitate the installation of gear, only with hand one is by recessed piece, and the sliding inclined-plane that relies on of gear one compresses the first elastic element, finally fixes.
As preferably, the circumferencial direction of described axle is provided with at least three equally distributed opening slots.
By technique scheme, arrange gear when at least 3 above-mentioned interface arrangment reinforced shafts rotate and can bear larger torque and moment of torsion, gear not easily shakes.
Compared to existing technology, the advantage of a kind of self-locking gear shaft that the utility model provides is: without the need to additional axial restraint part, and without the need near the shaft shoulder, the manufacturing procedure of axle saves time and resource less, and the assembly precision of gear is high.

Embodiment
With reference to accompanying drawing, the utility model self-locking gear shaft embodiment is described in further details.
See Fig. 1 to Fig. 7, self-locking gear shaft comprise axle 1, gear 2, recessed piece 3, the first elastic element 4, second elastic element 5, slide block 61, push rod 62 and projection 63, wherein slide block 61, push rod 62 are arranged to one with projection 63.
See Fig. 4 and Fig. 5, the axle 1 of described self-locking gear shaft circumferentially offer some opening slots 11, this example exemplifies offers three opening slots 11 for example, the first elastic element 4 is provided with bottom described opening slot 11, first elastic element 4 the other end is connected with recessed piece 3, described recessed piece of 3 slips are connected to the inwall of opening slot 11, described recessed piece 3 axial direction along axle 1 be set to inclined-plane 31.
See Fig. 2 and Fig. 3, described gear 2 evenly offers identical with opening slot 11 quantity in gear shaft hole wall 24 circumferencial direction, shape but draw-in groove 23 that the degree of depth different identical from size, draw-in groove 23 is opened in the middle position of gear shaft hole wall 24, be communicated with and be provided with slide block 61 with the slideway 21 of draw-in groove 23, slide block 61 and push rod 62 one be connected, slide block 61 is connected to the end of slideway 21 by the second elastic element 5, push rod 62 slippage is connected in push rod slideway 22, push rod slideway 22 is communicated with slideway 21 with draw-in groove 23 and the end face running through gear 2 leads to the external world, it is for convenience detach that push rod 62 is provided with projection 63.
See Fig. 1, Fig. 6 and Fig. 7, when gear 2 is installed, axial direction along axle 1 inserts as shown in Figure 6 from right to left, when gear 2 is stuck in recessed piece 3, by recessed piece 3, gear 2 is slipped into hand along the inclined-plane 31 on recessed piece 3, make in recessed piece 3 draw-in groove 23 be stuck on gear 2 by the first elastic element 4 for recessed piece 3, circumferentially all the other recessed pieces 3 also snap in simultaneously, add gear 2 when axle 1 rotates and can obtain larger torque, when disassembly is desired, the projection 63 on push rod 62 is pinned with hand, central axis direction towards gear 2 pushes hard and makes the slide block 61 be located in slideway 21 extrude recessed piece 3 to make recessed piece 3 to move downward, illustrate that when push rod 62 abuts to axial plane slide block 61 has been pressed onto axial plane and now can have easily taken off gear 2 away from axle direction once drawing by the projection 63 of the setting on push rod 62 with upper/lower positions by recessed piece 3, push rod 62 is sent out to be pulled recovery at the effect lower push-rod 62 of the second elastic element 5, here illustrate that the first elastic element 4 and the second elastic element 5 are set to spring, and the rigidity of the first elastic element 4 is far longer than the rigidity of the second elastic element 5, first elastic element 4 is set to brute spring.
