Abstract
The invention discloses a kind of new rack, including rack body（3）, in rack body（3）The upper setting gear teeth（1）, in rack body（3）Interior setting race ring（2）.The beneficial effects of the invention are as follows：The present invention is reasonable in design, simple in construction.Each composition and ratio of rack provided by the invention are moderate, substantially increase the heat resistance and thermal diffusivity of rack, so as to ensure rack normal operation, extend the service life of rack, and the rack of the present invention does not contain rare elemental nickel, molybdenum and manganese, and manufacturing cost is low, simultaneously, the composition species of gear is less so that manufacturing process is more easy, and then reduces manufacturing cost.
Description
Technical field
The present invention relates to mechanical field, more particularly, to a kind of new rack.
Background technology
Rack is the special gear that a kind of tooth is distributed on bar shape.Rack also divides spur rack and diagonal-cut rack, is used respectively with straight spur gear and helical gears pairing；The flank profil of rack non-involute for straight line（It is then plane for the flank of tooth）, it is infinitely great roller gear equivalent to reference radius.In rack work, easily occur that bad broken teeth, deformation, lubricant effect, quick abrasion, vibrations are big and these big problems of noise.
The content of the invention
The present invention provides a kind of new rack for this, including rack body, the gear teeth is set on rack body, race ring is set in rack body to solve present problems.Preferably, it is iron and other elements that the composition of the gear teeth and rack body, which includes carbon, 1.5~2% copper, surplus that mass percent is 0.8~1%,.
The beneficial effects of the invention are as follows：
The present invention is reasonable in design, simple in construction.Each composition and ratio of rack provided by the invention are moderate, substantially increase the heat resistance and thermal diffusivity of rack, so as to ensure rack normal operation, extend the service life of rack, and the rack of the present invention does not contain rare elemental nickel, molybdenum and manganese, and manufacturing cost is low, simultaneously, the composition species of gear is less so that manufacturing process is more easy, and then reduces manufacturing cost.
Brief description of the drawings
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein：
Fig. 1 is the front view of the present invention.
Embodiment
All features disclosed in this specification, or disclosed all methods or during the step of, in addition to mutually exclusive feature and/or step, can combine in any way.
Any feature disclosed in this specification, unless specifically stated otherwise, can alternative features equivalent by other or with similar purpose replaced.I.e., unless specifically stated otherwise, each feature is an example in a series of equivalent or similar characteristics.
As shown in Fig. 1 a kind of new rack, including rack body, the gear teeth is set on rack body, race ring is set in rack body.Preferably, it is iron and other elements that the composition of the gear teeth and rack body, which includes carbon, 1.5~2% copper, surplus that mass percent is 0.8~1%,.
The beneficial effects of the invention are as follows：
The present invention is reasonable in design, simple in construction.Each composition and ratio of rack provided by the invention are moderate, substantially increase the heat resistance and thermal diffusivity of rack, so as to ensure rack normal operation, extend the service life of rack, and the rack of the present invention does not contain rare elemental nickel, molybdenum and manganese, and manufacturing cost is low, simultaneously, the composition species of gear is less so that manufacturing process is more easy, and then reduces manufacturing cost.
The invention is not limited in foregoing embodiment.The present invention expands to any new feature disclosed in this manual or any new combination, and disclose any new method or process the step of or any new combination.
