Abstract
The utility model discloses a removable abrasion part's rack, including the rack body, be equipped with embedded rack on the rack body, all be equipped with tooth on rack body and the embedded rack, rack body both ends are equipped with the shaft shoulder, all be equipped with the locating hole on rack body and the interior inserted tooth, the locating hole on connection piece and rack body and the embedded rack passes through screw fixed connection. The utility model discloses a set up embedded rack in the middle of the rack is inside, is convenient for change the rack that the degree of wear is serious, need not change whole rack, change easy operation, installation firmly, be favorable to sparingly manufacturing cost, resources are saved.
Description
Technical field
The utility model relates to mechanical field, is specifically related to a kind of tooth bar of replaceable abrading section.
Background technique
Rack and pinion composition pinion and rack, the translation of tooth bar can be converted into the rotation of gear, also the rotation of gear can be converted to the translation of tooth bar, rack pinion is the kind of drive more common in mechanical field, utilize the engagement transferring power between gear and motion, have the advantages that compact structure, efficiency are high, the life-span is long.Therefore gear rack is more and more widely used in industrial production, and existing tooth bar adopts foundry goods mostly, foundry goods tooth bar easily weares and teares, particularly the neutral position of tooth bar, uses for a long time, and wearing and tearing are unavoidable, for meeting working system needs, tooth bar after wearing and tearing must be changed, add cost of production so undoubtedly, cause again the significant wastage of material simultaneously.
Model utility content
Model utility object: the purpose of this utility model is the tooth bar providing a kind of replaceable abrading section for deficiency of the prior art, does not need whole tooth bar to change, is conducive to saving cost of production, economizes on resources.
Technological scheme: for achieving the above object, the tooth bar of a kind of replaceable abrading section described in the utility model, comprise tooth bar body, embedded tooth bar is provided with in the middle of described tooth bar body, described tooth bar body and embedded tooth bar are equipped with teeth, described tooth bar body two ends are provided with the shaft shoulder, and described tooth bar body and interior inserted tooth are equipped with positioning hole, and connecting sheet is screwed with the positioning hole on tooth bar body and embedded tooth bar and is connected.
Further, the quantity of described connecting sheet is 4.
Preferably, described teeth are straight-tooth tooth.
Preferably, described tooth bar body and embedded tooth bar adopt high tensile aluminium alloy to make.
Compared with prior art, the beneficial effects of the utility model are:
1, the tooth bar of a kind of replaceable abrading section described in the utility model, by arranging embedded tooth bar at tooth bar bosom, being convenient to change the tooth bar of the serious intermediate portion of the degree of wear, not needing whole tooth bar to change, be conducive to saving cost of production, economize on resources.
2, embedded tooth bar is fixedly connected with by connecting sheet with tooth bar body by the utility model, simple to operate, installs firmly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is stereogram of the present utility model.
In figure: 1 tooth bar body, 2 embedded tooth bars, 3 teeth, 4 shaft shoulders, 5 connecting sheets, 6 positioning holes.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further.
The tooth bar of a kind of replaceable abrading section as shown in Figure 1-2, comprise tooth bar body 1, embedded tooth bar 2 is provided with in the middle of described tooth bar body 1, described tooth bar body 1 and embedded tooth bar 2 are equipped with teeth 3, described tooth bar body 1 two ends are provided with the shaft shoulder 4, described tooth bar body 1 and embedded tooth bar 2 are equipped with positioning hole 6, and described connecting sheet 5 is screwed with the positioning hole on tooth bar body 1 and embedded tooth bar 2 and is connected.
The quantity of connecting sheet described in the present embodiment is 4.
Teeth 3 described in the present embodiment are straight-tooth tooth.
The body of tooth bar described in the present embodiment 1 and embedded tooth bar 2 adopt high tensile aluminium alloy to make.
When changing wearing and tearing teeth in the present embodiment, only need embedded tooth bar 2 to pull down with the connecting sheet 5 of tooth bar body 1, then change embedded tooth bar 1, use 4 connecting sheets 5 to be fixed through positioning hole 6 with by retaining screw respectively.
Embodiment is only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
