Abstract
The utility model discloses a kind of high strength waveform tooth bar, described tooth bar is made up of some positions tooth, and described position tooth is connected with buckle between the tooth of position, and described tooth bar is segmented gradually thick structure.According to the normal tooth bar degree of wear used, readjust the flank of tooth thickness of each teeth portion of tooth bar, guarantee tooth bar to a certain extent in use for some time, tooth bar even wearing, avoid because excessive wear makes section of rack sink, reduce the working life of overall operation mechanism.
Description
Technical field
The utility model belongs to mechanical field, is specifically related to a kind of high strength waveform tooth bar.
Background technique
Tooth bar is divided into spur rack and diagonal-cut rack, uses respectively at straight toothed spur gear and helical gear pairing; The flank profil of tooth bar is straight line non-involute is then plane for the flank of tooth, and being equivalent to reference radius is infinitely great cylindrical gears.
After using a period of time, the teeth portion of tooth bar has certain wearing and tearing, and according to the different application of tooth bar, easily cause tooth bar to wear and tear uneven, neutral position is owing to often using comparatively both sides of wearing and tearing comparatively serious.
Therefore, need a kind of new technological scheme to solve the problem.
Model utility content
Model utility object: for above-mentioned prior art Problems existing and deficiency, the purpose of this utility model is to provide a kind of tooth bar being convenient to later maintenance.
Technological scheme: the utility model discloses a kind of high strength waveform tooth bar, described tooth bar is made up of some positions tooth, and described position tooth is connected with buckle between the tooth of position, described tooth bar is segmented gradually thick structure.According to the normal tooth bar degree of wear used, readjust the flank of tooth thickness of each teeth portion of tooth bar, guarantee tooth bar to a certain extent in use for some time, tooth bar even wearing, avoid because excessive wear makes section of rack sink, reduce the working life of overall operation mechanism.
As further optimization of the present utility model, the teeth portion of tooth bar described in the utility model is trapezium structure, and on the right side of it, angle of inclined-plane and vertical surface is less than the angle of inclined-plane, left side and vertical surface.
As further optimization of the present utility model, the angle of inclined-plane, right side described in the utility model and vertical surface is 2.3 °-5.4 °.
As further optimization of the present utility model, the position described in the utility model tooth number of teeth is 10-15 tooth, and the flank of tooth thickness being positioned at same position tooth is consistent.
As further optimization of the present utility model, between different parts tooth described in the utility model, flank of tooth thickness difference controls at 0.05-0.15mm.
The utility model is by the abrasion condition according to tooth bar diverse location, different parts tooth is adopted to form new tooth bar, position for serious wear adopts the position tooth that flank of tooth thickness is thicker, the position that the degree of wear is comparatively light adopts the position tooth that flank of tooth thickness is relatively thin, the tooth bar that the flank of tooth thickness mutual buckle of position tooth is together connected to form, after use one section of situation, efficiently solves section of rack tooth surface abrasion and seriously causes problems such as sinking.
Beneficial effect: the utility model compared with prior art, have the following advantages: the utility model forms tooth bar by adopting the position tooth of different flank of tooth thickness to carry out integration, its configuration flexibility is large, position for serious wear can carry out changing without the need to changing whole tooth bar in time, replacement operation is simple, solve tooth bar later maintenance cost, and tooth bar of the present utility model effectively reduces the number of stoppages produced because tooth bar wearing and tearing are inconsistent in operation, has good economic benefit.

Fig. 2 is rack teeth structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, illustrate the utility model further, these mode of executions should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
As shown in Figure 1, a kind of high strength waveform tooth bar of the present utility model, tooth bar is made up of some positions tooth, and between position tooth with position tooth, buckle is connected, and tooth bar is segmented gradually thick structure, according to the normal tooth bar degree of wear used, readjust the flank of tooth thickness of each teeth portion of tooth bar, guarantee tooth bar to a certain extent in use for some time, tooth bar even wearing, avoid, because excessive wear makes section of rack situation of sinking occur, reducing the working life of overall operation mechanism.
As shown in Figure 2, the teeth portion of tooth bar of the present utility model is trapezium structure, and on the right side of it, angle of inclined-plane and vertical surface is less than the angle of inclined-plane, left side and vertical surface.
The angle of inclined-plane, right side described in the utility model and vertical surface is 2.3 °-5.4 °, and the best is 3.5 °.
The position of the present utility model tooth number of teeth is 10-15 tooth, and the flank of tooth thickness being positioned at same position tooth is consistent.
Between different parts tooth of the present utility model, flank of tooth thickness difference controls at 0.05-0.15mm.
The utility model is by the abrasion condition according to tooth bar diverse location, different parts tooth is adopted to form new tooth bar, position for serious wear adopts the position tooth that flank of tooth thickness is thicker, the position that the degree of wear is comparatively light adopts the position tooth that flank of tooth thickness is relatively thin, the tooth bar that the flank of tooth thickness mutual buckle of position tooth is together connected to form, after use one section of situation, efficiently solves section of rack tooth surface abrasion and seriously causes problems such as sinking.
The utility model forms tooth bar by adopting the position tooth of different flank of tooth thickness to carry out integration, its configuration flexibility is large, position for serious wear can carry out changing without the need to changing whole tooth bar in time, replacement operation is simple, solve tooth bar later maintenance cost, and tooth bar of the present utility model effectively reduces the number of stoppages produced because tooth bar wearing and tearing are inconsistent in operation.
