Abstract
The invention discloses an assembly plastic gear. The assembly plastic gear comprises a left half gear body and a right half gear body. The left half gear body and the right half gear body are assembled to form the complete gear. A key groove is formed in a center hole of the left half gear body, two left protrusions are symmetrically arranged on the right plane of the left half gear body, two symmetrical left grooves are formed between the two left protrusions, two right grooves are symmetrically formed in the left plane of the right half gear body, and two right protrusions are symmetrically arranged between the right grooves. Through the mode, the assembly plastic gear is formed by assembling the left half gear body and the right half gear body, a center rotation shaft of the gear does not need to be disassembled during assembling, replacement is more convenient, matching is compacter, glue can be additionally used for bonding, and the firmness is good.
Description
Technical field
The present invention relates to plastic cement gear design field, particularly relate to a kind of assembling plastic cement gear.
Background technique
Plastic cement products application is more extensive, and particularly engineering plastics are applied more in industry.Engineering plastics have Multiple Type, wherein ultra-high molecular weight polyethylene has superpower wear resistance, self lubricity, the advantage such as strength ratio is higher, stable chemical nature, aging quality resistance are strong, gets the attention and applies, and even replaces in some aspects gear to carry out work.
Although the gear that plastic cement is made does not have the bearing capacity of metal gear large, but teeth plastic wheel has, and quality is slim and graceful, output is high, cost is low, work in water and be not also afraid of the advantage such as get rusty, work can be carried out by alternative metals gear completely in place in some underloadings, but plastic cement gear poor stability, need to often safeguard and change, cumbersome.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of assembling plastic cement gear, easy accessibility, and conformability is good.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of assembling plastic cement gear is provided, comprise: left half heel teeth and right half heel teeth, described left half heel teeth and right half heel teeth are combined into a complete gear, in the center hole of described left half heel teeth, be provided with a keyway, in the right side plane of described left half heel teeth, be symmetrically arranged with two left side projections, two symmetrical left side grooves are set between described two left side projections, in the left side plane of described right half heel teeth, be symmetrically arranged with two the right grooves, between the groove of described the right, be symmetrically arranged with two the right projections.
In a preferred embodiment of the present invention, the width of described left side groove equals the width of the right projection.
In a preferred embodiment of the present invention, the width of described left side projection equals the width of the right groove.
In a preferred embodiment of the present invention, the distance between described two left side grooves equals two distances between the projection of the right.
In a preferred embodiment of the present invention, the distance between described two left side projections equals two distances between the groove of the right.
The invention has the beneficial effects as follows: one that the present invention points out assembling plastic cement gear, combined by left half heel teeth and right half heel teeth, when installation, without the Gear center rotating shaft of dismantling, change also more conveniently, coordinate closely, can bond by additional glue, soundness is good.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing, wherein:
Fig. 1 is a kind of structural representation of assembling one preferred embodiment of plastic cement gear of the present invention;
Fig. 2 is the structural representation of parts 1 in Fig. 1;
Fig. 3 is the structural representation of parts 2 in Fig. 1;
In accompanying drawing, the mark of each parts is as follows: 1, left half heel teeth, 2, right half heel teeth.
Embodiment
To the technological scheme in the embodiment of the present invention be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skills, not making all other embodiments that obtain under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1 to Fig. 3, the embodiment of the present invention comprises:
A kind of assembling plastic cement gear, comprise: left half heel teeth 1 and right half heel teeth 2, described left half heel teeth 1 and right half heel teeth 2 are combined into a complete gear, in the center hole of described left half heel teeth 1, be provided with a keyway, in the right side plane of described left half heel teeth 1, be symmetrically arranged with two left side projections, two symmetrical left side grooves are set between described two left side projections, in the left side plane of described right half heel teeth 2, be symmetrically arranged with two the right grooves, between the groove of described the right, be symmetrically arranged with two the right projections.
The one assembling plastic cement gear that the present invention points out coordinates closely, and the width of described left side groove equals the width of the right projection.
Further, the width of described left side projection equals the width of the right groove, when installation, can fix with glue, is connected firmly.
Further, the distance between described two left side grooves equals two distances between the projection of the right, and conformability is good.
Further, the distance between described two left side projections equals two distances between the groove of the right, upper and lower symmetrical connection, good stability.
In sum, one that the present invention points out assembling plastic cement gear, compared with common plastic cement gear, has adopted split design, when installation without disengage gear central shaft and bearing, dismounting and safeguard also more conveniently, conformability is good.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
