Abstract
The utility model relates to an automatic door opening and closing device, in particular to a door driving device. The connecting structure of a shaft and a bevel gear comprises a bevel gear and a shaft, wherein the shaft comprises a connecting portion and a spindle portion. The connecting structure is characterized in that a clamping groove is arranged on the tail of the bevel gear, and a clamping pin matched with the clamping groove is arranged on the connecting portion of the shaft. The connecting structure transmits torque through the clamping groove on the tail of the bevel gear and the clamping pin which is matched with the clamping groove and arranged on the shaft, guarantees minimum size of the bevel gear through matching of the clamping groove and the clamping pin, and also can meet the requirement of transmitting large torque.
Description
Technical field
The utility model relates to a kind of automatic switch door gear, relates in particular to a kind of drive unit.
Background technology
General bevel gear and axle be linked as key or pin link, after the bevel gear size was determined, the size of small end also just determined, spool maximum size also just definite substantially, adopt this structure for the bigger bevel gear of structure, can reach the requirement of transmitting large torque.But for transmitting the big still little structure of axle journal of torsion, the on-link mode (OLM) of key or pin is just inapplicable, because the size of key and pin is subjected to the restriction of axle.
Summary of the invention
In order to address the above problem, the utility model provide a kind of simple and reasonable, promptly can guarantee the size minimum of bevel gear can satisfy the axle of transmitting large torque requirement and the syndeton of bevel gear again.
To achieve these goals, the utility model is mainly solved by the following technical programs: the syndeton of a kind of axle and bevel gear, comprise bevel gear and axle, described axle comprises connecting portion and main shaft position, it is characterized in that, the afterbody of described bevel gear offers draw-in groove, and the connecting portion of described axle is provided with the dop that is complementary with described draw-in groove.
As preferably, the tail end of above-mentioned bevel gear is socketed with axle sleeve.
As preferably, above-mentioned axle sleeve in the form of a ring.
The utility model offers draw-in groove by the afterbody bevel gear, with on axle, be provided with the dop that is complementary with draw-in groove and carry out transfer torque, the size minimum that closely cooperates and promptly can guarantee bevel gear through draw-in groove and dop can satisfy the requirement of transmitting large torque again.

The specific embodiment
Below in conjunction with accompanying drawing 1-7, the specific embodiment of the technical solution of the utility model is described in further detail.
Embodiment: the syndeton of a kind of axle and bevel gear, comprise bevel gear 1 and axle 3, described 3 comprises connecting portion 5 and main shaft position 6.The afterbody of bevel gear 1 offers draw-in groove 4, and the connecting portion 5 of described axle 3 is provided with the dop 7 that is complementary with described draw-in groove 4 and carries out transfer torque.Dop 7 can be milled flat and guaranteed concentricity with the connecting hole of bevel gear 1 by the main shaft portion 3 of axle 3.
In order to reinforce bevel gear 1 and axle 3 be connected, make its in use bevel gear 1 afterbody do not open and axle 2 breaks away from from bevel gear 1, be socketed with the axle sleeve 2 that is bad shape at the tail end of bevel gear 1.
Claims (3)
