Abstract
The invention discloses a novel plastic gear which comprises a gear body. A shaft hole is arranged in the center of the gear body, at least three fan-shaped straight slots are arranged on the gear body and encircle the shaft hole, radiating grooves are arranged on the shaft hole, an abrasion-resistant layer is arranged in the shaft hole, and the radiating grooves are arranged in centers of lower surfaces of the fan-shaped straight slots. The novel plastic gear is provided with the fan-shaped straight slots and the radiating grooves, accordingly, heat generated when the gear moves and rubs with a shaft can be dissipated timely, and problems of aggregation of abrasion of the gear and deformation caused by high heat are solved. Besides, the novel plastic gear is high in abrasion resistance, stable in transmission performance and long in service life.
Description
Technical field
The present invention relates to a kind of gear, particularly a kind of Novel plastic gear belongs to the mechanical transmission component technical field.
Background technique
Gear is mechanical part common during people live, by intermeshing transmission.And plastic gear is a kind of gear of making take plastics as material.Plastic gear has lightly, cost is low and the characteristics of easy processing.Plastic gear is widely used in the industries such as weaving, lathe, plate-making, instrument, food.Existing gear does not have radiating structure, if in the gear movement process with untimely the distributing of the fricative heat of axle, will cause gear wear aggravation and produce distortion, affect its transmission stability and working life.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: the Novel plastic gear that has proposed a kind of good heat dissipation effect, long service life.
Technical solution of the present invention is achieved in that a kind of Novel plastic gear, comprises the gear body; The central authorities of described gear body have axis hole; Have fan-shaped groove around axis hole on the described gear body; Open radiating groove on the described axis hole.
Preferably, be provided with wearing layer in the described axis hole.
Preferably, described radiating groove is opened the central authorities at fan-shaped groove lower surface.
Preferably, the number of described fan-shaped groove is at least three.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
Novel plastic gear of the present invention owing to being provided with fan-shaped groove and radiating groove, with the fricative heat of axle, has overcome the gear wear aggravation and the generation problem on deformation that cause because heat is higher in the time of can in time distributing gear movement.Wear-resisting property of the present invention is good, and transmission performance is stable, long service life.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1 is the stereogram of Novel plastic gear of the present invention;
Wherein: 1, gear body; 2, axis hole; 3, fan-shaped groove; 4, radiating groove; 5 wearing layers.
Embodiment
Below in conjunction with accompanying drawing the present invention is described.
Of the present invention a kind of Novel plastic gear as shown in Figure 1 comprises gear body 1; The central authorities of described gear body 1 have axis hole 2; Have fan-shaped groove 3 around axis hole 2 on the described gear body 1; Open radiating groove 4 on the described axis hole 2; Be provided with wearing layer 5 in the described axis hole 2; Described radiating groove 4 is opened the central authorities at fan-shaped groove 3 lower surfaces; The number of described fan-shaped groove 3 is at least three.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
Novel plastic gear of the present invention owing to being provided with fan-shaped groove and radiating groove, with the fricative heat of axle, has overcome the gear wear aggravation and the generation problem on deformation that cause because heat is higher in the time of can in time distributing gear movement.Wear-resisting property of the present invention is good, and transmission performance is stable, long service life.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
