Abstract
The utility model discloses a kind of gear of replaceable external tooth, comprise core wheel and external tooth, the edge of described core wheel is evenly distributed with the slot of left end sealing, right-end openings, the tooth root that the root of this external tooth has and this slot matches, the left side wall that is formed with right mounting hole, this slot on this tooth root is provided with left mounting hole, in this left mounting hole and this right mounting hole, pass and have clamping bolt, and this external tooth is alumina ceramic materials preparation.The utility model has the advantages that: comparatively save, be particularly useful for hot environment.
Description
Technical field
The present invention relates to technical field of transmission, especially relate to a kind of gear of replaceable external tooth.
Background technique
Gear is as the most common transmission part, and its outer odontotripsis is very fast.Even if after one of them external tooth damages, this gear is all scrapped, and causes great waste, the gear especially using under the condition of high temperature, this phenomenon is particularly serious.
Summary of the invention
The object of this invention is to provide a kind of gear of replaceable external tooth, it has comparatively saves, and is particularly useful for the feature of hot environment.
The technical solution adopted in the present invention is: a kind of gear of replaceable external tooth, comprise core wheel and external tooth, the edge of described core wheel is evenly distributed with the slot of left end sealing, right-end openings, the tooth root that the root of this external tooth has and this slot matches, the left side wall that is formed with right mounting hole, this slot on this tooth root is provided with left mounting hole, in this left mounting hole and this right mounting hole, pass and have clamping bolt, and this external tooth is alumina ceramic materials preparation.
The section of described slot and the section of this tooth root are non-circular.
The advantage that the present invention has is: comparatively save, be particularly useful for hot environment.The external tooth of the gear of replaceable external tooth of the present invention and core wheel adopt split-type structural, after damaging appears in one of them external tooth, only need this external tooth to change, very convenient, and have avoided scrapping of whole gear, comparatively save.Meanwhile, its external tooth adopts alumina ceramic materials preparation, thereby while being applied in hot environment, the flank of tooth of external tooth is difficult for heat seal phenomenon occurs, thereby working life is longer.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is that the gear of the replaceable external tooth of embodiments of the invention is looked sectional view (part) the master of decomposing state;
Fig. 2 is the right elevation of Fig. 1.
In figure: 10, core wheel, 11, slot, 12, left mounting hole; 20, external tooth, 21, tooth root, 22, right mounting hole; 30, clamping bolt.
Embodiment
Embodiment, is shown in shown in Fig. 1 and Fig. 2: a kind of gear of replaceable external tooth, comprises and being separated from each other and independent core wheel 10 and the external tooth 20 of manufacturing.Wherein, the edge of this core wheel 10 is evenly distributed with the slot 11 of left end sealing, right-end openings, the tooth root 21 that the root of this external tooth 20 has and this slot 11 matches.That is, the shape of this tooth root 21 is same as this slot 11, and after this tooth root 21 is inserted in this slot 11, this external tooth 20 has been embedded on this core wheel 10.Preferably, it is non-circular that the section of the section of this slot 11 and this tooth root 21 is ellipse, polygonal etc., thereby avoid this external tooth 20 to produce rotation.Further say, the left side wall that is formed with right mounting hole 22, this slot 11 on this tooth root 21 is provided with left mounting hole 12, in this left mounting hole 12 and this right mounting hole 22, passes and has clamping bolt 30., by this clamping bolt 30, this tooth root 21 can not deviate from this slot 11.And this external tooth 20 is alumina ceramic materials preparation.Like this, removable external tooth 20 has reduced the user cost of this gear, and external tooth 20 prepared by stupalith has been avoided heat seal phenomenon, has extended the working life of this gear.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
