Abstract

The utility model provides a combined gear, which leads a position of a gear surface, which is easiest to be wore to be continuously updated through converting an absolute position of the gear surface, wherein the outer ring of a gear disc of the combined gear is equipped with a gear, the inner ring is equipped with a groove, a shaft disc is inlaid in the groove, the groove and the shaft disc are transitionally matched, and the gear disc and the shaft disc are fixed by an articulation screw. Simultaneously, the circumference of the end surface of the gear disc is evenly distributed with 12 articulation via holes, secondly, the circumference of the end surface of the shaft disc, which is same to the gear disc is also evenly distributed with 12 screwed holes, the front end of the screwed hole is also equipped with articulation holes, and the circumference between the screwed hole on the end surface of the shaft disc and the shaft hole is evenly distributed with 6 burden reduction holes.

Description

Built up gear

Technical field

The utility model relates to a kind of gear.

Background technique

Gear is the parts commonly used of mechanical transmission mechanism, use very extensive at present, and its structure is based on integrated type, give no cause for much criticism for general driving mechanism like this, but for special driving mechanism, integral gear often causes the replacing of whole gear owing to flank of tooth concentrated wear, therefore be necessary to develop novel gear and save energy and reduce the cost.

Summary of the invention

The utility model provides a kind of built up gear, and it makes the flank of tooth can constantly obtain upgrading in the position of easy wearing and tearing by the absolute position of the conversion flank of tooth.

The utility model is achieved in that built up gear comprises gear disk (1), reel (4), specifically: the outer ring of gear disk (1) is gear (2), inner ring is being established groove (3), inlaying reel (4) in the groove (3), between be transition fit, fixing between gear disk (1) and the reel (4) by articulation screw (5); Simultaneously, uniform 12 articulation through holes on the end face circumference of gear disk (1); Secondly, also uniform 12 tapped holes on reel (4) the end face circumference identical with gear disk (1), the front end of tapped hole also is an articulation hole, and on the circumference between reel (4) end-face helical hole and the axis hole uniform 6 holes (6) of lightening the burden.

Effect of the present utility model is to increase the service life, and has also reduced the difficulty of changing as damaging, and reduces cost.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Accompanying drawing 1 is the plan view of the utility model built up gear.

Accompanying drawing 2 is left views of the utility model built up gear.

Among the figure: 1. gear disk, 2. gear, 3. groove, 4. reel, 5. articulation screw, 6. Reduction of Students' Study Load hole.

Embodiment

Among the figure, after gear disk (1) and reel (4) are made, reel (4) is embedded in the groove (3) of gear disk (1), at the through hole and the articulation screw (5) of screwing on after tapped hole aligns, it is fastening to twist neat back.When regular maintenance, twist articulation screw (5), turning gear wheel disc (1) makes the relative position of itself and reel (4) obtain conversion, the articulation screw (5) and fastening of screwing on after the alignment again then.

Claims

1. a built up gear comprises gear disk, reel, it is characterized in that: the outer ring of gear disk is a gear, and inner ring is being established groove, is inlaying reel in the groove, between be transition fit, between gear disk and the reel by the articulation screw.

2. built up gear according to claim 1 is characterized in that: uniform 12 articulation through holes on the end face circumference of gear disk.

3. built up gear according to claim 1 is characterized in that: uniform 12 tapped holes on the reel end face circumference identical with gear disk, the front end of tapped hole also is an articulation hole.

4. built up gear according to claim 1 is characterized in that: uniform 6 Reduction of Students' Study Load holes on the circumference between reel end-face helical hole and the axis hole.
