Background technique
Gear be usually all with gear shaft with interference fit or the mode of card key clamping, carry rotation by gear shaft.At some, the strength of gear teeth is required it is not very high comparatively gearwheel occasion, people can run into the outer rim size and shape without the need to changing gear sometimes, and the situation that can match from the gear shaft of different size and shape, but gear size in the market and model are all fixing, the size and shape of gear shaft holes cannot be changed, the requirement that a gear matches from the gear shaft of different size and shape simultaneously can not be met.Therefore, require it is not very high comparatively gearwheel occasion at some to the strength of gear teeth, there is axis hole size and shape and can not change in current gear, the problem that Applicable scope is too narrow.
Model utility content
The purpose of this utility model is, provides a kind of gear changing axis hole size and shape, and it has axis hole size and shape and can change, the feature that Applicable scope is wider.
The technical solution of the utility model: a kind of gear changing axis hole size and shape, comprises the first wheel body, is provided with axis hole inside the first wheel body, the first round, external side was provided with card key, and the first wheel body is connected with the second wheel body by card key; Second wheel body outer ring is provided with teeth, is provided with teeth groove between teeth, and the second wheel body inner ring is provided with concaver; Concaver is interval with circlip groove and the first bolt hole, circlip groove position is corresponding with card key position; Fix through face body lid between first wheel body and the second wheel body, face body lid size is mated with concaver, and face body covers and is provided with the position projection corresponding with circlip groove and the first bolt hole and the second bolt hole; Face body lid and concaver are fixed by link.
Above-mentioned a kind ofly change in the gear of axis hole size and shape, in described circlip groove, be provided with rubber lining.
Aforesaidly a kind ofly change in the gear of axis hole size and shape, described projection is wrapped with elastic caoutchouc.
Aforesaidly a kind ofly change in the gear of axis hole size and shape, described circlip groove and bolt hole have two groups at least, and described link is the assembly parts of screw bolt and nut.
Compared with prior art, the utility model has axis hole size and shape and can change, the feature that Applicable scope is wider.The whole gear of the utility model adopts the composite structure of the first wheel body and the second wheel body, wherein the second wheel body size and shape is constant, the size and shape of the first wheel body can be changed flexibly, the size and shape changing whole wheel body axis hole is more brought by the first wheel body, to be applicable to the gear shaft of different size and shape, Applicable scope is more wide in range.

Embodiment
Below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation limited the utility model.
Embodiment.Change a gear for axis hole size and shape, form as shown in Fig. 1,2,3,4,5, comprise inside the first wheel body 1, first wheel body 1 and be provided with axis hole 2, be provided with card key 3 outside the first wheel body 1, the first wheel body 1 is connected with the second wheel body 4 by card key 3; Second wheel body 4 outer ring is provided with teeth 5, is provided with teeth groove 6, second wheel body 4 inner ring and is provided with concaver 7 between teeth 5; Concaver 7 is interval with circlip groove 8 and the first bolt hole 9, circlip groove 8 position is corresponding with card key 3 position; Fix through face body lid 10 between first wheel body 1 and the second wheel body 4, face body lid 10 size is mated with concaver 7, and face body lid 10 is provided with the position projection 11 corresponding with circlip groove 8 and the first bolt hole 9 and the second bolt hole 12; Face body lid 10 is fixed by link 13 with concaver 7.Rubber lining 14 is provided with in described circlip groove 8.Described projection 11 is wrapped with elastic caoutchouc 15.Described circlip groove 8 and bolt hole have two groups at least, and described link 13 is the assembly parts of screw bolt and nut.
When using, take out the second wheel body 4, according to the size and shape of gear shaft, select the first wheel body 1 with the axis hole 2 that matches with it, then the first wheel body 1 and the second wheel body 4 are combined installation, by the card key 3 on the first wheel body 1, snap in the circlip groove 8 on the concaver 7 of the second wheel body 4, rubber lining 14 is provided with in circlip groove 8, rubber lining 14 is strong elastic rubber, it can ensure good contact between the first wheel body 1 and the second wheel body 4, and when gears meshing rotates beginning or stops, a buffer function strengthening gradually or weaken can be played to stressed between card key 3 and circlip groove 8, then face body lid 10 is coordinated fixing with concaver 7, the elastic caoutchouc 15 that face body lid 10 projection 11 is wrapped with, can ensure that card key 3 is fixed by projection 11 and circlip groove 8 more firm, and stressed by between the screw bolt and nut of link 13, elastic caoutchouc 15 makes dynamics increase gradually, and even larger than original strength, what contact segment was fixed is rationally firm, then the gear will assembled, is installed on the gear shaft of needs.
When the gear of formed objects and shape is required for the gear shaft of other size and shapes, only need unload original gear, unscrew the screw bolt and nut on link 13, take off face body lid 10, concaver 7 is unloaded, then selects to match the first wheel body 1 of axis hole 2 with gear shaft size and shape, connect corresponding with the circlip groove 8 on the second wheel body 4 for the card key 3 of the first wheel body 1, cover face body lid 10, then use the screw bolt and nut of link 13 by face body lid 10 and concaver 7 fixation.Fig. 4 shows the larger gear of an axis hole 2 combined according to gear shaft, Fig. 5 shows the gear that axis hole 2 place combined according to gear shaft offers draw-in groove 16, the utility model can according to the different size and shapes of gear shaft, be combined into any gear matched, Applicable scope widely.
In order to make up whole gear be due to combination form, and the shortcoming of the structural strength caused, the all material of whole gear uses forged steel material, forged steel material is owing to having good intensity, hardness and toughness, there is good combination property, making up the deficiency of this gear structure intensity by promoting the strength of materials.Here gear is when processing and fabricating originally, all complete processing as required, often gear size and shape will be used according to user's reality, select the second wheel body 4, then gear shaft specification is commonly used according to difference, process various that coordinate from the second wheel body 4, with the first wheel body 1 with the corresponding axis hole 2 of different conventional gear shaft, carry out satisfying the demand of maximum magnitude.
