Abstract
The invention relates to a plastic gear which is characterized by comprising a left half gear and a right half gear, wherein the left half gear and the right half gear are combined to form a complete gear; a key slot is arranged in a central hole of the left half gear; two left projections are symmetrically arranged on the right plane of the left half gear; two symmetrical left grooves are arranged between the two left projections; two right grooves are symmetrically arranged in the left plane of the right half gear; two right projections are symmetrically arranged between the right grooves. Compared with the ordinary plastic gear, the plastic gear of the invention adopts split design, can be mounted without dismounting a central shaft and a bearing of the gear, and is convenient to dismount and maintain and good in cooperation property.
Description
Technical field
The present invention relates to a kind of plastic cement gear.
Background technique
Plastic cement products Application comparison is extensive, and particularly engineering plastics are applied more in the industry.Engineering plastics have Multiple Type, wherein ultra-high molecular weight polyethylene has superpower wear resistance, self lubricity, the advantages such as strength ratio is higher, stable chemical nature, aging quality resistance are strong, get the attention and apply, and even replace gear to carry out work in some aspects.Although the gear that plastic cement is made does not have the bearing capacity of metal gear large, but teeth plastic wheel has that quality is slim and graceful, output is high, cost is low, work in water and be not also afraid of advantages such as getting rusty, work can be carried out by alternative metals gear completely in the place of some underloadings, but plastic cement gear poor stability, need often to carry out safeguarding and changing, cumbersome.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide a kind of technological scheme of plastic cement gear.
Described a kind of plastic cement gear, it is characterized in that comprising 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, a keyway is provided with in the center hole of described left half heel teeth, the right side plan of described left half heel teeth is symmetrically arranged with two left side projections, two symmetrical left side grooves are set between described two left side projections, the left side plan of described right half heel teeth is symmetrically arranged with two the right grooves, is symmetrically arranged with two the right between the groove of described the right protruding.
Described a kind of plastic cement gear, is characterized in that the width of described left side groove equals the protruding width in the right.
Described a kind of plastic cement gear, is characterized in that the width of described left side projection equals the width of the right groove.
Described a kind of plastic cement gear, the distance that it is characterized in that between described two left side grooves equals the distance between two the right projections.
Described a kind of plastic cement gear, the distance that it is characterized in that between described two left side projections equals the distance between two the right grooves.
The present invention is combined by left half heel teeth and right half heel teeth, without the need to Gear center rotating shaft of dismantling during installation, changes also more convenient, and coordinate closely, can bond by additional glue, soundness is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with Figure of description, the present invention will be further described:
A kind of 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, a keyway is provided with in the center hole of described left half heel teeth 1, the right side plan of described left half heel teeth 1 is symmetrically arranged with two left side projections, two symmetrical left side grooves are set between described two left side projections, the left side plan of described right half heel teeth 2 is symmetrically arranged with two the right grooves, is symmetrically arranged with two the right between the groove of described the right protruding.
The width of the left side of the present invention groove equals the protruding width in the right, the width of left side projection equals the width of the right groove, can fix with glue during installation, be connected firmly, distance between two left side grooves equals the distance between two the right projections, and conformability is good, and the distance between two left side projections equals the distance between two the right grooves, upper and lower symmetry connects, good stability.
The present invention, compared with common plastic cement gear, have employed split design, and without the need to disengage gear central shaft and bearing during installation, dismantle and safeguard also more convenient, conformability is good.
