Abstract
The utility model relates to a novel gear pair, which comprises a concave gear and a convex gear, wherein teeth of the concave gear are sunk from the two sides of the concave gear to the middle, and teeth of the convex gear are protruded from the two sides of the convex gear to the middle. In the novel gear pair, the transmission between shafts can be smoothly and precisely achieved, and the surfaces of the gear teeth are not easily damaged because of smaller surface pressure of the gear teeth.
Description
Affiliated technical field
The utility model relates to a kind of hardware, especially, is a kind of gear pair.
Background technique
In the hardware machinery field, gear pair is a kind of common transmission, because its stable drive, and accurate velocity ratio can be provided, therefore be widely used in the transmission between each.Total institute is known, power transmission between the gear pair is by the contact between the gear teeth, and the present gear pair gear teeth and the contact segment between the gear teeth are straight line in theory, actual is a narrow rectangle (having micro-strain behind the tooth surface pressurized), its area of contact is limited, tooth surface pressure is bigger, so gear surface damages easily.
Summary of the invention
At the problems referred to above, the purpose of this utility model is to provide a kind of new gear pair, and this new gear pair not only can steadily and accurately realize the between centers transmission, and has less tooth surface pressure, and tooth surface is not fragile.
The technological scheme that its technical problem that solves the utility model adopts is: this new gear pair comprises concave gear and convex gear, the gear teeth of described concave gear are from described concave gear two side direction intermediate recess, and the gear teeth of described convex gear protrude in the middle of two side direction of described convex gear.
As preferably, the profile line of described concave gear and described convex gear is involute.
The beneficial effects of the utility model are: this kind new gear pair is when transmission, the theoretical Line of contact of described concave gear and convex gear is a camber line, and its length is greater than the straight line Line of contact under the identical gear width, therefore, the pressure of tooth surface is less, and the gear teeth are not fragile.
Description of drawings
Fig. 1 is the side view of this new gear pair.
Fig. 2 is that the A-A of this Fig. 1 is to cut away view.
Embodiment
Fig. 1, embodiment illustrated in fig. 2 in, this new gear pair comprises concave gear 1 and convex gear 2, the gear teeth of described concave gear 1 are from described concave gear two side direction intermediate recess, the gear teeth of described convex gear 2 protrude in the middle of two side direction of described convex gear.
Above-mentioned new gear pair, the profile line of described concave gear 1 and described convex gear 2 is involute.
Above-mentioned new gear pair is when transmission, and the theoretical Line of contact of described concave gear 1 and convex gear 2 is a camber line, and its length is greater than the straight line Line of contact under the identical gear width, and therefore, the pressure of tooth surface is less, and the gear teeth are not fragile.
Claims (2)
1. new gear pair is characterized in that: comprise concave gear (1) and convex gear (2), the gear teeth of described concave gear (1) are from described concave gear two side direction intermediate recess, and the gear teeth of described convex gear (2) protrude in the middle of two side direction of described convex gear.
