The utility model provides a gear, includes fluted disc and connecting cylinder, the fluted disc is the annular, the fluted disc is equipped with and is located fluted disc border department and evenly distributed's tooth, the connecting cylinder is cylindricly just fluted disc cover is located on the connecting cylinder, connecting cylinder one end has to its outside convex fender edge, keep off along being annular convex form just keep off along the butt in fluted disc tip department, the connecting cylinder other end with be equipped with the location structure who can dismantle the connection between the fluted disc, fluted disc tip department is equipped with recessed connecting seat, keep off along with the connecting seat cooperatees just keep off along inlay in connecting seat department.

Further, the blocking edge and the connecting cylinder are integrally formed.

Furthermore, location structure includes holding ring and connecting rod, the holding ring cover is located the connecting cylinder other end, the connecting rod connect gradually in the holding ring the fluted disc with keep off on the edge.

Furthermore, the outer end of the connecting rod is provided with a convex blocking shoulder which is abutted against the positioning ring, and the inner end of the connecting rod is in threaded connection with the blocking edge.

Furthermore, the number of the connecting rods is a plurality of, and the connecting rods are circumferentially and uniformly distributed and connected to the positioning ring and the blocking edge.

Compared with the prior art, the gear provided by the invention not only can stably connect the fluted disc with the connecting cylinder, but also can be conveniently detached under the action of the positioning structure, and after the working process is carried out for a period of time, the fluted disc can be independently replaced after being worn, so that the practical cost of the composite gear is effectively reduced; simultaneously, owing to be connected through connecting cylinder and axle type part, the fluted disc plays transmission power effect, and the connecting cylinder plays the effect of being connected with axle type part stability, and such structure enables the fluted disc and shares the atress with the connecting cylinder, and suitable improvement the stability of whole combined type gear to still owing to keep off along the part to inlay in the connecting seat, effectual its compact structure nature that has improved like this, can also play certain prepositioning effect simultaneously.

Detailed Description

Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

Fig. 1 is a schematic structural diagram of a gear according to the present invention. The utility model provides a gear, includes fluted disc 10 and connecting cylinder 20, fluted disc 10 is the annular, fluted disc 10 is equipped with and is located fluted disc 10 border department and evenly distributed's tooth, connecting cylinder 20 is cylindricly just fluted disc 10 cover is located on the connecting cylinder 20, 20 one end of connecting cylinder has the convex fender edge 21 in its outside, keep off along 21 and be annular convex form just keep off along 21 butt in fluted disc 10 tip department, the connecting cylinder 20 other end with be equipped with the location structure who can dismantle the connection between the fluted disc 10, fluted disc 10 tip department is equipped with recessed connecting seat 11, keep off along 21 with connecting seat 11 cooperate just keep off along 21 inlay in connecting seat 11 department. The gear is composed of the fluted disc 10 and the connecting cylinder 20, the fluted disc 10 and the connecting cylinder 20 can be stably connected under the action of the positioning structure, the disassembly is convenient, the fluted disc 10 can be independently replaced after the fluted disc 10 is worn after a period of working process, and the practical cost of the composite gear is effectively reduced; simultaneously, owing to be connected with axle type part through connecting cylinder 20, fluted disc 10 plays the transmission power effect, and connecting cylinder 20 plays the effect of being connected with axle type part stability, and such structure enables fluted disc 10 and connecting cylinder 20 to share the atress, and suitable improvement the stability of whole combined type gear to still owing to keep off along 21 part and inlay in connecting seat 11, effectual its compact structure nature that has improved like this, can also play certain prepositioning effect simultaneously.
