Abstract
The invention discloses a gear, which comprises a body and teeth. The body comprises an axle hole; a connecting part is connected between the teeth and the body; and the teeth are quenched and tempered, so that a quenching and tempering layer is formed on the teeth. The teeth on the gear are quenched and tempered, the Brinell hardness of the teeth is controlled in a range of Brinell hardness (HB) 224-228, and the gear can be used for most of places requiring high-strength gears. Besides, because extra alloy is not added in the gear, the cost of the gear is low.
Description
Technical field
The invention belongs to field of mechanical technique, be specifically related to a kind of gear.
Background technique
Gear is to have tooth can mesh the mechanical component of transmitting movement and power continuously on the wheel rim.Gear is the intermeshing mechanical parts that tooth is arranged of ability, and the application of gear in transmission occurred very early.19 end of the centurys, generate cutting ratio juris and utilize the appearance in succession of the special purpose machine tool and the cutter of this principle cutting, along with the development of producing, the stationarity of gear operation comes into one's own.
Gear is divided into cylindrical gears, bevel gear, noncircular gear, tooth bar, worm and worm gear by its profile; The by tooth traces shape is divided into spur gear, helical gear, herringbone gear, curved tooth cylindrical gear; Surface by gear teeth place is divided into external gear, internal gear; Can be divided into cast gear, cutting gear, rolling gear, sintered gear(s) etc. by production method.
Along with the development of technology, during modern industry is produced, more and more need use the gear of big specification, corresponding, for the intensity of gear itself new challenge has been proposed also.In existing mode of execution, increase the intensity of gear usually through the mode that is included in other alloy of interpolation in the gear, but the alloy expensive that common these class methods need use is unfavorable for the control of cost of production.
Summary of the invention
The object of the present invention is to provide a kind of intensity height and the low gear of cost of production.
Be realization foregoing invention purpose, a kind of gear provided by the invention, this gear comprises:
Main body portion includes axis hole on the said main body portion;
Teeth are connected with joint between said teeth and the said main body portion;
Wherein, comprise texturizing layer on the said teeth.
As further improvement of the present invention, the Brinell hardness scope of said teeth is HB224 ~ 228.
As further improvement of the present invention, said teeth are through Quenching Treatment.
As further improvement of the present invention, the section area of said joint is much smaller than the section area of said teeth.
As further improvement of the present invention, said joint is through quenching with Subsequent tempering.
As further improvement of the present invention, said main body portion is through quenching with Subsequent tempering.
As further improvement of the present invention, the diameter of said axis hole is 175 millimeters.
As further improvement of the present invention, said main body portion is 380 millimeters along the length of longitudinal direction.
Compared with prior art, the present invention can be controlled to be HB224 ~ 228 with the Brinell hardness scope of teeth through on the teeth on the gear, making texturizing layer, satisfies the occasion of most of needs high tenacity gears, and owing to do not add extra alloy, cost is lower.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technological scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing relevant of the present invention in describing below only is some embodiments of the present invention, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of gear one mode of execution of the present invention.
Embodiment
Below will combine embodiment shown in the drawings to describe the present invention.But these mode of executions do not limit the present invention, and the conversion on the structure that those of ordinary skill in the art makes according to these mode of executions, method or the function all is included in protection scope of the present invention.
Join Fig. 1, introduce an embodiment of gear 10 of the present invention, in this mode of execution, this gear 10 comprises main body portion 11 and teeth 13.
Include axis hole 12 on the main body portion 11, be used to cooperate external bearing, and then linkage gear 10.
Be connected with joint 14 between teeth 13 and the main part.In this mode of execution, the cross-section area of joint 14 is much smaller than the section area of teeth 13.So the benefit of setting is, can significantly reduce the raw material use amount of joint 14 parts, reduces production costs.
Comprise texturizing layer 131 on the teeth 13, in this mode of execution, can be through for example to teeth 13 process quenching with Subsequent tempering, so that this texturizing layer 131 of formation on the teeth.The Brinell hardness scope of teeth 13 is HB224 ~ 228.Through teeth 13 are carried out quenching with Subsequent tempering, not adding under the prerequisite of extra alloy, improve the intensity of teeth 13 greatly, make gear 10 of the present invention can satisfy the occasion of most of needs high tenacity gears 10, and cost is lower.
As preferred embodiment, teeth 13 process Quenching Treatment, so intensity, hardness, wear resistance, fatigue strength and toughness significantly to improve teeth 13.
Distinguishingly, joint 14 is through quenching with Subsequent tempering.
Distinguishingly, main body portion 11 is through quenching with Subsequent tempering.
Distinguishingly, the diameter of axis hole 12 is 175 millimeters.
Distinguishingly, main body portion 11 is 380 millimeters along the length of longitudinal direction.
The present invention is through above-mentioned mode of execution; Has following beneficial effect: through to texturizing layer 131 is set on the teeth on the gear 10 13; Can the Brinell hardness scope of teeth 13 be controlled to be HB224 ~ 228; Satisfy the occasion of most of needs high tenacity gears 10, and owing to do not add extra alloy, cost is lower.
Be to be understood that; Though this specification is described according to mode of execution; But be not that each mode of execution only comprises an independently technological scheme, this narrating mode of specification only is for clarity sake, and those skilled in the art should make specification as a whole; Technological scheme in each mode of execution also can form other mode of executions that it will be appreciated by those skilled in the art that through appropriate combination.
The listed a series of detailed description of preceding text only is specifying to feasibility mode of execution of the present invention; They are not in order to restriction protection scope of the present invention, allly do not break away from equivalent mode of execution or the change that skill of the present invention spirit done and all should be included within protection scope of the present invention.
