Abstract

The utility model discloses an assembly-type sprocket which comprises an outer disk, an inner disk, screw holes, a shaft hole and sprocket grooves; the outer disk and the inner disk are mutually inlaid and assembled; the plurality of sprocket grooves with gear grooves with the same size are arranged on the outer disk; the sprocket grooves are arranged right in the center of a gear shape, so that the whole sprocket has interchangeability; twelve screw holes with the same size are sequentially arranged on the inner disk with equal distance; when the outer disk and the inner disk of the sprocket are mutually inlaid, and a screw is fixedly arranged on machinery through the screw holes on the inner disk. The assembly-type sprocket has the advantages of convenience in repairing, long service life and the like.

Description

Assembled chain wheel

Technical field

The utility model relates to a kind of sprocket wheel, relates in particular to a kind of assembled chain wheel.

Background technique

The sprocket wheel multidigit ferrous material pouring one-step forming sprocket wheel that uses in the crane parts at present, the sprocket wheel of this material in the middle of the unlatching running of machinery since between teeth groove and the teeth groove through long mutual friction mutually; The wearing and tearing that occur teeth groove are easily broken, and the interior disk of sprocket wheel is owing to long-time bearing mechanical part, the effect of the power that is squeezed simultaneously; Breaking of whole interior disk also very easily appears; Cause sprocket wheel to use, sprocket wheel self heaviness simultaneously causes flight-line maintenance personnel very inconvenience when the maintenance replacement; Machinery can't be operated normally, bring some unnecessary troubles for the production of enterprise.

The model utility content

The above-mentioned background technical problem that be to solve, the utility model provide a kind of long service life, assembled chain wheel easy to maintenance.

For realizing above-mentioned purpose; A kind of assembled chain wheel that the utility model provides; Comprise: outer disc, interior disk, screw, axis hole, sprocket groove, described outer disc and interior disk are inlayed mutually and are fitted together; On described outer disc, have the identical sprocket groove of several teeth groove sizes, described sprocket groove is positioned at the center of profile of tooth.

Equidistantly successively on the disk in described have 12 screws that size is identical.

The disc centre position has axis hole in described.

The utlity model has following beneficial effect in sum: prolong working life, is convenient to maintenance man's maintenance.

Description of drawings

Fig. 1 is the structural representation of a kind of assembled chain wheel of the utility model.

Wherein: the 1-outer disc; Disk in the 2-; The 3-screw; The 4-axis hole; The 5-sprocket groove.

Embodiment

As shown in Figure 1, a kind of assembled chain wheel comprises: outer disc, interior disk, screw, axis hole, sprocket groove; Described outer disc 1 is inlayed mutually with interior disk 2 and is fitted together; On described outer disc 1, have the identical sprocket groove 5 of several teeth groove sizes, described sprocket groove 5 is positioned at the center of profile of tooth, makes the whole chain wheel have interchangeability; Equidistantly successively on the disk 2 in described have 12 screws 3 that size is identical; After the outer disc 1 of sprocket wheel is embedded in together mutually with interior disk 2, just can be fixed on mechanically through the screw 3 on the interior disk 2 with screw, disk 2 central positions have axis hole 4 in described.

The utility model is to implement like this; In the middle of the running of machinery, wearing and tearing occur and break when the sprocket groove 5 of the outer disc 1 of sprocket wheel uses through long-time friction, perhaps when the interior disk 2 of sprocket wheel because after the effect of extruding force ruptures; The maintenance man just can replace whole sprocket wheel; Only need the wherein part of damaged fracture of replacement, sprocket wheel just can continue to use, and has guaranteed mechanical normal operation.

More than show and described basic principle of the utility model and the advantage of major character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.

Claims

1. assembled chain wheel comprises: outer disc, interior disk, screw, axis hole, sprocket groove is characterized in that: have the identical sprocket groove of several teeth groove sizes on the described outer disc, described sprocket groove is positioned at the center of profile of tooth.

2. a kind of assembled chain wheel according to claim 1 is characterized in that: equidistantly successively on the disk in described have 12 screws that size is identical.
