Abstract
The invention discloses a rolling friction gear and belongs to the technical field of mechanical transmission. The rolling friction gear is mainly composed of a rolling bearing, a gear shaft and a main wheel. The rolling bearing replaces teeth of a traditional gear, sliding friction between gear faces is changed to rolling friction, the friction coefficient becomes smaller, transmission efficiency is improved, and the service life of the gear is prolonged.
Description
Technical field
The present invention relates to the mechanical transmissioning technology field, especially a kind of new-type gear that changes the gear teeth face friction mode.
Background technique
During working gear, sliding friction takes place in the flank of tooth that is meshed inevitably, and tooth surface abrasion also certainly leads to, when tooth surface abrasion is serious, and gear teeth attenuation, the impact that gear operation produces just can cause break of gear tooth.
Summary of the invention
The problem to be solved in the present invention provides and a kind ofly can reduce tooth surface abrasion, is become the new-type gear of rolling friction by the sliding friction between the flank of tooth.
For solving the above problems, the scheme that the present invention adopts is: the edge that be installed in main wheel of several rolling bearings by the bearing shaft five equilibrium, form the gear that the flank of tooth is circular arc---rolling friction gear.Described rolling friction gear and ordinary gear are used in combination.During work, the flank of tooth of ordinary gear is stirred the bearing outer ring on the rolling bearing, and bearing outer ring band rolling element rotates together, and the flank of tooth of ordinary gear and bearing outer ring are made roll displacement simultaneously, forms rolling friction, also can stir ordinary gear by bearing.
In such scheme, described bearing shaft can be that diaxon is parallel with the installation form of main axle, also can be that diaxon intersects or diaxon interlaces.
Because adopt such scheme, the present invention compared with prior art has following beneficial effect:
1, gear tooth friction becomes rolling friction by sliding friction, and the gear tooth friction coefficient diminishes, transmission efficiency improves; The wheel odontotripsis diminishes, the life-span prolongation.
2, the present invention can use aspect face gear transmission and the space gear transmission, uses to be more suitable for aspect worm drive.In the transmission acting process of common worm screw, the friction of generation is big, heating value is big, causes that tooth surface abrasion is big, mechanism driving efficient is low.The present invention is applied on the worm gear, makes worm screw stir rolling bearing on the worm gear, form rolling friction, less traction, heating as a result less, little, the transmission efficiency of wearing and tearing improves.
3, practice of the present invention is found, the lead angle angle on the worm indexing cylinder is strengthened, and worm gear energy transmission worm screw utilizes this effect, can research and develop the new-type speed increaser that a kind of speed ratio is big, transmission efficiency is high.
Description of drawings
Figure of description is structural representation of the present invention.
Embodiment
Below in conjunction with the accompanying drawing example structure of the present invention is described further:
In structure shown in the drawings, several rolling bearings 1 are installed in the edge of main wheel 5 by bearing shaft 2, and each bearing outer ring 4 can both be with rolling element 3 to rotate around bearing shaft 2, every bearing shaft 2 and main axle 6 parallel installations.
