Abstract
The invention discloses a gear which consists of a group of steel columns with round cross sections and a pair of steel column fixing devices, wherein the steel columns are arrayed to form a circle and fixed by the steel column fixing devices. The invention also discloses a rack matched with the gear. The contact surfaces of the gear and the rack of the invention are completely attached without clearances during the transmission, thereby improving the transmission precision and the transmission speed.
Description
Technical field
The present invention relates to a kind of gear and tooth bar, specifically is high gear of a kind of transmission accuracy and tooth bar.
Background technique
Conventional at present tooth bar face is to be trapezoidal (as shown in Figure 1), and the gear surface tooth that matches also is trapezoidal, adopts trapezoidal rack and pinion to occur following problem easily in transmission process:
1, in the transmission process, gapped when gear and gear engagement;
2, because the existence in gap has influenced the precision of transmission;
3, transmission speed is slow.
Summary of the invention
Goal of the invention:, the invention provides high gear of a kind of transmission accuracy and tooth bar in order to solve the deficiencies in the prior art.
Technological scheme: in order to realize above purpose, a kind of gear of the present invention, 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 by the steel column fixing device.As preferred version of the present invention, described gear is made of 10 steel columns.
The invention also discloses the tooth bar that is complementary with said gear whole is waveform, and the tooth bar upper surface is made of circular groove and arc convex.
Beneficial effect: a kind of gear provided by the invention and the tooth bar that mates with this gear thereof compared with prior art have the following advantages:
1, because gear and tooth bar adopt the arc design, in transmission process, do not have the gap, improved the precision of transmission;
2, because gear of the present invention and the gapless design of tooth bar, make in gear and the tooth bar transmission stationarity good, stability is high, and speed is fast.
Description of drawings
Fig. 1 is the sectional drawing of prior art middle rack;
Fig. 2 is the structural representation of gear of the present invention and tooth bar.
Embodiment:
Below in conjunction with specific embodiment, further illustrate the present invention, should understand these embodiments only is used to the present invention is described and is not used in and limit the scope of the invention, after having read the present invention, those skilled in the art all fall within the application's claims to the modification of the various equivalent form of values of the present invention and limit.
Embodiment
A kind of gear 1 as shown in Figure 2 is that circular steel column 12 and a pair of steel column fixing device 11 constitutes by one group of cross section; Steel column 12 is ten, arranges to constitute a circumference, and fixing by steel column fixing device 11.
In the present embodiment, also disclose the tooth bar 2 that mates with said gear 1, this tooth bar 2 upper surfaces integral body is waveform, and tooth bar 2 upper surfaces are made of circular groove 21 and arc convex 22.
During transmission, the steel column 12 on the gear 1 moves along the arc-shaped wave Slippage on the tooth bar 2, and when steel column 12 was fitted with tooth bar 2 upper surfaces, there was not the gap in steel column 12 with tooth bar 2 upper surfaces, has realized the accurate transmission of gear 1.
Claims (3)
1. gear is characterized in that: this gear (1) is circular steel column (12) and a pair of steel column fixing device (11) formation by one group of cross section; Steel column (12) is arranged and is constituted a circumference, and fixing by steel column fixing device (11).
2. gear according to claim 1 is characterized in that: described gear (1) is made of 10 steel columns.
3. according to the tooth bar of the described gear coupling of claim 1, it is characterized in that: this tooth bar (2) is whole to be waveform, and tooth bar (2) upper surface is made of circular groove (21) and arc convex (22).
