Abstract
The invention discloses a circular-arc-tooth-trace gear and rack transmission. The structure of the circular-arc-tooth-trace gear and rack transmission form mainly comprises a circular-arc-tooth-trace cylindrical gear I and a circular-arc-tooth-trace rack II. Gear teeth for the circular-arc-tooth-trace gear and rack transmission are arch teeth, and tooth traces for the circular-arc-tooth-trace gear and rack transmission are circular arc traces so that a longer contact line can be obtained during transmission, and the bearing capacity of a gear pair can be improved easily. The middle section tooth contour of the gear during transmission is an involute, other end section tooth contour of the gear are evenly-changed hyperbolic envelope lines which are similar to the involute; and the middle section tooth contour of the rack during transmission is the same as that of a spur rack, and other section tooth contours of the rack are envelope lines of cone generating lines. During installation, the circular-arc-tooth-trace gear and rack transmission is not sensitive to the center distance. The gear teeth of the transmission are symmetrical with respect to the middle section, and axial force is avoided during transmission. According to the circular-arc-tooth-trace gear and rack transmission, the bearing capacity is high, the transmission efficiency is high, the stability is good, noise is low, and axial force is avoided; and the circular-arc-tooth-trace gear and rack transmission is a novel industrial basic part and suitable for large-scale application and popularization.
Description
Technical field
The invention belongs to mechanical transmission fields, particularly relate to a kind of arc tooth line rack pinion, particularly one and hold
Loading capability is big, transmission efficiency is high, stationarity is good, noise is low, without the arc tooth line rack pinion of axial force.Described gear teeth
The gear teeth of the gear in bar transmission have concavo-convex two flank of tooth, and on the gear teeth flank of tooth, the transversal along facewidth direction is circular arc line, and
On the intermediate cross-section of the gear teeth, its flank profil line is involute, and each cross section contour from the gear teeth middle section to both ends of the surface is uniform mistake
The hyp envelope crossed, the gear teeth have the geometrical property symmetrical about middle section；Tooth bar in described rack pinion
On the flank of tooth, the transversal along facewidth direction is straight line, and the profile angle of its male and female face flank profil line is phase on the intermediate cross-section of the gear teeth
With, its flank profil line is identical with modulus spur rack, and each cross section contour from the gear teeth middle section to both ends of the surface is that circular cone is female
The envelope of line, the gear teeth have the geometrical property symmetrical about middle section.
Background technology
Rack pinion is actuating device conventional in mechanical industry, has stable drive, and efficiency is high, and bearing capacity is big
Etc. advantage, it is widely applied in the mechanical engineering fields such as lathe, food machinery, woodworking machinery, armarium, finance device.
But along with the development of each engineering field, the combination property of rack pinion is more had higher requirement.
In the rack pinion system of present stage, straight-tooth, helical gear and double helical tooth etc. are gear teeth forms more typically,
But all there are some obvious defects in the rack pinion pair using these several tooth traces.Spur gear rack gear is nibbled at the gear teeth
During conjunction, the gear teeth are the most engaging-in along the whole facewidth and nibble out, and gear teeth load subjected to presents bigger sudden change,
Engagement process easily produces shock and vibration.Helical gear tooth bar driving contact line is not parallel with axis, can produce axially during transmission
Component, shafting structure is complicated, and friction loss increases.There is escape in the middle of the gear of double helical tooth rack pinion, add and set
Standby overall dimension and consumption of materials.Meanwhile, assembling time, its symmetry it is difficult to ensure that, its middle gear must use floating
Supporting, easily causes unbalance loading and floating gear axial float, increases mesh vibration, and then the inefficacy of the pair that drives up.
It is an object of the invention to provide a kind of novel for said gear rack gear form is not enough present in the transmission
Unique arc tooth line rack pinion, particularly a kind of bearing capacity is big, transmission efficiency is high, stationarity is good, noise is low, nothing
The arc tooth line rack pinion of axial force.This kind of rack pinion form contacts line than same parameter straight-tooth tooth in transmission
Wheel rack gear is long, and combines the feature of its concavo-convex flank of tooth, and its bearing capacity is higher than straight-tooth gear rack gear, and its gear teeth are same
Herringbone bear rack gear is the same, all has the characteristic symmetrical about its middle section, avoids employing helical teeth in transmission process
Bigger axial force during wheel gear rack gear, and assembling time due to its flank of tooth be tooth trace be the concavo-convex flank of tooth of circular arc line,
Can realize automatic centering, easy to assembly, its drive linear degree can be improved simultaneously.To sum up, this kind of rack pinion type
Formula can substitute for existing rack pinion pattern, it is achieved large-scale industrial application.
Summary of the invention
In order to overcome conventional gears rack gear form deficiency in production and transmission process and problem, and retain as far as possible
Conventional gears rack gear form advantage in transmission process, it is an object of the invention to provide and a kind of have new tooth
Rack pinion, a kind of bearing capacity is high, transmission efficiency high, stationarity is good, noise is low, without the Novel toothed of axial force
