Abstract
The invention discloses a novel semi-gear. The novel semi-gear comprises a gear body, the semi-circumference of the gear body is provided with gear teeth, the other semi-circumference of the gear body is a smooth surface, the gear body is made through powder metallurgy, the central position of the gear body is provided with a through hole, a plastic bearing sleeve is arranged inside the through hole, and a pin hole is formed on the side of the smooth surface and is communicated with the through hole. The novel semi-gear has the advantages that half of the circumference of the semi-gear is in a toothed shape with teeth to enable a transmission shaft can be fixed at positions of any angle within 180 degrees, and the life of the novel semi-gear can be prolonged by utilizing powdered metal and the plastic bearing sleeve.
Description
Technical field
The present invention relates to gear technique field, be specifically related to a kind of novel half gear.
Background technique
Having many uses of gear, is the strength member in various machinery, as the wrist-watch of using in lathe, aircraft, steamer and daily life, electric fan etc. all will be used various gears.The kind of gear is a lot, has spur gear wheel, cylindric spiral gear, spiral gear, straight toothed bevel gear, spiral bevel gear, worm gear etc.Wherein use morely, also better simply is spur gear wheel, claims again standard cylinder gear, for the gear of not doing complete cycle motion, adopts also relatively waste of spur gear wheel, and processing cost is also high.
Summary of the invention
The object of the invention is to defect and deficiency for prior art, a kind of novel half gear is provided.
For achieving the above object, the technical solution used in the present invention is:
A kind of novel half gear of the present invention, comprise gear body, the semi-circumference of gear body is provided with the gear teeth, another semi-circumference is smooth surface, described gear body is made by powder metallurgy, and gear body neutral position is provided with through hole, is provided with plastic shaft bearing sleeve in through hole, smooth surface one side is provided with pin-and-hole, and pin-and-hole is connected with through hole.
As preferably, described pin-and-hole is two smooth surface one sides that are set up in parallel at gear body.
As preferably, described through hole two ends are provided with chamfering.
Adopt after said structure, beneficial effect of the present invention is: on half circumference of gear, having half is the dentation that has teeth, make transmission shaft can be fixed on any angular position within the scope of 180 degree, adopt powdered metal and plastic shaft bearing sleeve can make the life-span of half gear be extended.
Accompanying drawing explanation
In order to be illustrated more clearly in technological scheme 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.
Fig. 1 is structural representation of the present invention.
In figure: 1, gear body, 2, the gear teeth, 3, through hole, 4, plastic shaft bearing sleeve, 5, pin-and-hole.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in Figure 1, a kind of novel half gear of the present invention, comprise gear body 1, the semi-circumference of gear body 1 is provided with the gear teeth 2, another semi-circumference is smooth surface, described gear body 1 is made by powder metallurgy, comprise copper, cobalt, nickel, iron and Tungsten carbite, gear body 1 neutral position is provided with through hole 3, in through hole 3, be provided with plastic shaft bearing sleeve 4, smooth surface one side is provided with pin-and-hole 5, pin-and-hole 5 is two smooth surface one sides that are set up in parallel at gear body, pin-and-hole 5 is connected with through hole 3, plastic shaft bearing sleeve 4 has avoided metal gear directly to contact with metal shaft, solved the problem of frictional heat, effectively extended working life.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, although the present invention discloses as above with preferred embodiment, yet not in order to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, when can utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be the content that does not depart from technical solution of the present invention, any simple modification of above embodiment being done according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
