Abstract
The utility model belongs to the technical field of mechanical parts, in particular relates to a high-strength rack, and solves the technical problems that the prior art is unreasonable in design and the like. The rack comprises a strip-type body, wherein a plurality of uniformly distributed teeth are formed on one side of the body and integrally connected with the body. The rack is characterized in that the thickness of the body is at least three times the height of the teeth. Compared with the prior art, the high-strength rack has the advantages that the rack has a simple structure and is reasonable in design and high in transmission efficiency, mechanical strength and bearing capacity.
Description
Technical field
The utility model belongs to the mechanical parts technical field, especially relates to a high tenacity tooth bar.
Background technique
Tooth bar also divides spur rack and diagonal-cut rack, uses with straight toothed spur gear and helical gear pairing respectively; The flank profil of tooth bar is that the straight line non-involute then is the plane to the flank of tooth, and being equivalent to reference radius is infinitely great cylindrical gears.
For example, the tooth bar [application number: CN201010295200.6] that the Chinese patent document discloses a kind of gear and mated with this gear, this gear are that circular steel column and a pair of steel column fixing device constitutes by one group of cross section; Steel column is arranged and is constituted a circumference, and fixes through the steel column fixing device.Tooth bar with the said gear coupling is also disclosed among the present invention.The precision and the transmission speed of transmission have been improved in gear of the present invention and tooth bar surface of contact when the transmission no gap of fitting fully.
Though such scheme has the precision and the transmission speed of transmission preferably.But still exist the high inadequately technical problem of mechanical strength.
Summary of the invention
The purpose of the utility model is to the problems referred to above, provides a kind of reasonable in design, simple in structure, and transmission efficiency height and mechanical strength are high, the high tenacity tooth bar that bearing capacity is strong.
For achieving the above object; The utility model has adopted following technical proposal: this high tenacity tooth bar; Comprise the body that is strip, have some equally distributed teeth in the one side of body, described teeth and body are connected as a single entity structure; It is characterized in that described body thickness is at least three times of teeth height.
In above-mentioned high tenacity tooth bar, described teeth are isosceles trapezoid.
Compared with prior art, the advantage of this high tenacity tooth bar is: reasonable in design, simple in structure, transmission efficiency height and mechanical strength are high, and bearing capacity is strong.
Description of drawings
Fig. 1 is the structural representation that the utility model provides.
Among the figure, body 1, teeth 2.
Embodiment
As shown in Figure 1, this high tenacity tooth bar comprises the body 1 that is strip, has some equally distributed teeth 2 in the one side of body 1, and teeth 2 are connected as a single entity structure with body 1, and body 1 thickness is at least three times of teeth 2 height, and described teeth 2 are isosceles trapezoid.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as body 1, teeth 2 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain the essence of the utility model more easily; It all is contrary with the utility model spirit being construed to any additional restriction to them.
Claims (2)
1. high tenacity tooth bar; Comprise the body (1) that is strip, have some equally distributed teeth (2) in the one side of body (1), described teeth (2) are connected as a single entity structure with body (1); It is characterized in that described body (1) thickness is at least three times of teeth (2) height.
