Embodiment
below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation limited the utility model.
embodiment.A kind of composite structure gear, form as shown in Figure 1 and Figure 2, comprise the first wheel body 1, first wheel body 1 offers axis hole 2, first space 3 and second space 4 successively by Inside To Outside, first instance part 5 between axis hole 2 and the first space 3, second instance part 6 between first space 3 and second space 4, second instance part 6 is offered screw hole 7, through screw rod 8 in screw hole 7, one end of screw rod 8 is connected with screw rod knob 9 in the first space 3, and the other end of screw rod 8 is connected with card key 10 in second space 4; Be provided with card key hole 11 outside first wheel body 1, card key 10 is through card key hole 11; Described card key 10 is connected with the second wheel body 12, is provided with circlip groove 13 inside the second wheel body 12, is provided with teeth 14, is provided with teeth groove 15 between teeth 14 outside the second wheel body 12.Described card key 10 is provided with rubber sleeve 16.Described first space 13, second space 4 and card key 10 all have one group at least.
when running gear failure, the operation gear damaged being unloaded from wheel shaft, according to size and the teeth shape of running gear, assembling the equipment gear of size the same as running gear and teeth shape.First the first wheel body 1 of equipment gear is enclosed within wheel shaft, screw rod 8 is put into from second space 4, make screw rod 8 through the screw hole 7 set by second instance part 6, then the card key 10 of grip rubber sleeve 16 is put into from second space 4, and screw rod 8 is connected with the hole spiral that card key 10 is stayed; Then take out and the second wheel body 12 running gear matches, make equipment gear consistent with the size and teeth shape running gear, be enclosed within the first wheel body 1, rotate the second wheel body 12 or the first wheel body 1, card key hole 11 on first wheel body 1 and the circlip groove 13 on the second wheel body 12 are docked, with screw rod 8, card key 10 is headed in the circlip groove 13 on the second wheel body 12, rotate the screw rod knob 9 in the first space 3, first wheel body 1 and the second wheel body 12 are connected firmly, connect four groups of such card keys 10 successively, complete the assembling of gear.After required operation gear orders arrival again, can equipment gear be changed, again change operation gear, by equipment gear dismounting, wiped clean, be placed on spare area for subsequent use.
rubber sleeve 16 is wherein strong elastic rubber, can ensure good contact between the first wheel body 1 and the second wheel body 12, and can play suitable buffer function; First space 3 and second space 4 can play the effect of heat radiation; Wherein card key 10 is keys of whole gear, and card key 10 uses the fine finishing of forged steel material to be made, and has good intensity, hardness and toughness, has good combination property; Card key 10 and corresponding circlip groove 13 thereof can process adult shape, column or other shapes, to make whole gear have better combination property.
if desired the gear of other size and dimensions, only needs card key 10 to retract, and takes off the second wheel body 12 that the second wheel body 12 changes corresponding coupling.Here gear, when processing and fabricating originally, should be all complete processing as required, can order the different size of needs and the second wheel body 12 of different teeth shape, better meet needs, complete production; Fig. 3 shows the second wheel body 12 of the another kind of teeth 14 of changing on the first wheel body 1, their combination, constitutes a new gear.
