Abstract
The utility model relates to a kind of high performance turbine curved tooth face gear transmission systems, it is characterized in that gear pair includes circular arc profile arc cylindrical gear and circular arc profile curved tooth face gear, the flank of tooth of circular arc profile roller gear includes concave and convex surface two parts, the flank of tooth of circular arc profile curved tooth face gear equally includes concave and convex surface two parts, and along tooth length direction in the trend that comes to a point, the convex surface of circular arc profile arc cylindrical gear and the concave surface of circular arc profile curved tooth face gear are intermeshed in transmission process；Beneficial effect is the gear pair by the way that the engaged transmission between male and fomale(M&F) circular arc can more steadily accurately realization axis be driven, and profile radius of curvature is big, easy running-in, and easily formation oil film, gear capacity improve, stress concentration reduction.
Description
Technical field
The utility model relates to mechanical transmission fields, more particularly to a kind of high performance turbine curved tooth face gear power train
System.
Background technique
In mechanical transmission fields, gear pair is a kind of common, extensive transmission of application field.Because it is driven steady
It is fixed, there is accurate transmission ratio, be capable of providing accurate speed regulation, is widely used in transmitting load between each axis.However one
It needs the gear of extraordinary flute profile to bear huge weight under a little heavy duty work environment, needs to develop the flute profile of new configuration, in tradition
Straight-tooth face gear on the basis of introduce the arc-shaped tooth gear of circular arc profile and can complete to improve gear on the basis of orthogonal transmission
Bearing capacity extends gear service life, and circular arc profile can be such that composite curve radius increases, and improves contact strength, stress
The easy running-in of even wearing.
It is low in order to solve power density in currently available technology, it is driven unstable etc. technical bottleneck, the utility model mentions
A kind of high performance turbine curved tooth face gear transmission system is gone out, which not only can more surely and accurately realize between centers
Transmission, and gear teeth single-direction transmission bearing capacity can be greatly improved, reduce tooth surface pressure, the gear teeth are not susceptible to be broken or roll over
It is disconnected, and tooth surface is also hardly damaged.Both it had been able to satisfy the Practical Project demand in high-speed overload precision drive field, has filled up related skill
Art blank, and can produce biggish social benefit and economic benefit.
Summary of the invention
A kind of high performance turbine curved tooth face gear power train that in order to overcome the deficiencies of the prior art, the utility model provides
System, it is characterised in that gear pair includes circular arc profile arc cylindrical gear and circular arc profile curved tooth face gear, circular arc profile cylinder
The flank of tooth of gear includes concave and convex surface two parts, and the flank of tooth of circular arc profile curved tooth face gear equally includes concave and convex surface two
Point, and along tooth length direction in the trend that comes to a point, the convex surface of circular arc profile arc cylindrical gear and circular arc profile arc in transmission process
The concave surface of flank of tooth gear is intermeshed；The flank profil of circular arc profile arc cylindrical gear and circular arc profile curved tooth face gear is circular arc
The flute profile feature of flank profil, circular arc profile curved tooth face gear is along tooth length direction, and facewidth cross section can increase with face gear radius
Greatly gradually at topping trend, opposite facewidth cross section gradually appears tooth root inscribe with the reduction of face gear radius；Circle-arc tooth
It is arc-shaped gear, circular arc profile curved tooth face gear edge on the teeth directional direction of wide arc cylindrical gear and circular arc profile curved tooth face gear
The flank profil section of axial direction is different everywhere.
The utility model has the beneficial effects that: this kind of novel gear pair transmission when, the arc field of conjugate action of each gear teeth
Bearing capacity compared to plane is promoted significantly；Contact line is a camber line when driving contact, and it is wide that length is greater than identical gear
Straight contact line under degree, therefore, the pressure of tooth surface is smaller, and the gear teeth are hardly damaged.
Detailed description of the invention
Fig. 1 is circular arc profile arc cylindrical gear.
Fig. 2 is the single gear teeth of circular arc profile curved tooth face gear.
Fig. 3 is circular arc profile curved tooth face gear.
Fig. 4 is a kind of high performance turbine curved tooth face gear transmission system.
Specific embodiment
The embodiments of the present invention is described with reference to the drawings, the utility model is carried out below with reference to Fig. 1-Fig. 4 specific
Explanation.
A kind of high performance turbine curved tooth face gear transmission system includes circular arc profile arc cylindrical gear and circular arc profile arc
Flank of tooth gear, the flank of tooth of the circular arc profile roller gear include concave and convex surface two parts, circular arc profile curved tooth face gear
The flank of tooth equally includes concave and convex surface two parts, and along tooth length direction in the trend that comes to a point, circular arc profile curved tooth in transmission process
The convex surface of roller gear and the concave surface of circular arc profile curved tooth face gear are intermeshed, and the transmission of one direction heavy load may be implemented.
The flank profil of above-mentioned circular arc profile arc cylindrical gear and circular arc profile curved tooth face gear is circular arc profile, circular arc
The flute profile feature of flank profil curved tooth face gear is along tooth length direction, and facewidth cross section can increase with face gear radius gradually at tooth
The trend that comes to a point is pushed up, opposite facewidth cross section gradually appears tooth root inscribe with the reduction of face gear radius.
Above-mentioned novel gear pair can realize more steady accurate transmission on the basis of keeping original orthogonal transmission,
And the bearing capacity of gear is improved, extend gear service life.
The above is only the better embodiment of invention, not does any restrictions to the utility model, all according to this
Utility model essence still falls within the utility model to any modification, change and equivalence changes made by embodiment of above
Within the protection scope of technology.
