The purpose of this utility model is to be directed to the above-mentioned problems in the prior art, there is provided a kind of performance is stable, no
Eely built-up gear.
The purpose of this utility model can be realized by following technical proposal：A kind of built-up gear, including gear wheel and
The pinion gear of assembling is combined with gear wheel, the outer end of the gear wheel and pinion gear is both provided with the gear teeth along part, its feature
It is, the pinion gear lower part has optical axis section, and combination convex block and the installation of protrusion are respectively arranged with the optical axis section
Convex block, has the restriction groove to pinion gear inner recess on the end face of the optical axis section, confession is offered on the gear wheel
The fixing groove that pinion gear optical axis section stretches into, the fixing groove both sides extend be useful for combine convex block it is matched combine it is recessed
Groove, is circumferentially evenly distributed with several pin holes on the gear wheel, and the pin hole is connected with combining groove, and on pin hole
Fixed pin is provided with, is provided with the gear wheel wheel body with limiting the matched restriction round platform of groove, the gear wheel
Axis hole is both provided with the gear wheel and pinion gear, the axis hole is interconnected through groove is limited with restriction round platform.
The technique effect of this built-up gear：When built-up gear is machined and assembled, the optical axis section of pinion gear is put
It is placed in the fixing groove of gear wheel, tilts pinion gear and coordinate the combination convex block of one end with combining groove, then pass through limiting slot
Combination with limit round table limits the relative position between pinion gear and gear wheel, finally by several pins on gear wheel
Hole mounting pin further realizes fixation.
In a kind of above-mentioned built-up gear, the width of the installation convex block is less than the length of combination convex block.Prevent from installing
Convex block is wide cause pinion gear can not normal combination assembling, it is convenient that pinion gear combination convex block is embedded into combination groove.
It is interference fitted and connects in a kind of above-mentioned built-up gear, between the fixed pin and pin hole, and fixed pin
Lower face is born against on combination convex block and installation convex block.
In a kind of above-mentioned built-up gear, the circumferential cross-section of the fixed pin is rectangle.Rectangular fixed pin
It is not easy in working gear because vibrations slip, so as to influence the normal stability of built-up gear.
In a kind of above-mentioned built-up gear, the edge of the combination convex block is machined with the chamfering of arc-shaped.Prevent
The sharp edge of combination convex block causes to scratch to gear wheel, while plays the role of guiding.
In a kind of above-mentioned built-up gear, radius surface is big, upper top surface radius is small to go to the bottom for the spacing groove shape
It is round table-like.Polygon limiting slot plays fast positioning, spacing effect, and built-up gear is also ensure that while improving installation effectiveness
It is not easy to slip.
Compared with prior art, this built-up gear realizes peace using combination convex block with combining the assembly method of groove combination
Fill effect, at the same by set fixed pin come further it is fixed with it is spacing, there is performance stabilization, be not easy to slip.
