Abstract
The utility model discloses a wobbled involute face-gear drive, which has two conical gears of indexing cone taper angles of approaching 90 DEG. The conical gears also are face gears. The teeth difference of the two conical gears is 1 and the two conical gears are installed on the two shafts of the same shaft line. A face gear (3) is installed on the oblique handle of a crank shaft. A face gear (4) is installed on a straight output shaft. The two gears are engaged with each other. The crank shaft rotates a circle, the oblique handle also rotates a circle. The face gear (3) rolls along the face gear (4). The face gear (3) swings a circle and the face gear rotates a tooth because the teeth difference is 1, then the speed reduction can be realized. Speed reducers are used the drive mechanism, which have large drive ratio, high overlap coefficient, small sliding coefficient, small geometric pressure coefficient and small specific pressure coefficient. So the utility model has the advantages of high capability, high efficiency, small size and light weight.
Description
In mechanical transmission, the utility model can be used as the speed reducer of various machinery.
The utility model can be beautiful with the harmonic gear ratio at aspects such as design, materials, processing.But its technical requirements height, and require to use elastomeric senior alloy material.Technical requirements difficulty of the present utility model is low, uses general gear material commonly used just passable.This kind driving mechanism has outstanding advantage at present, popularize in an all-round way can do fully to obtain.
The purpose of this utility model is and can provides bearing capacity height, efficient height, little, the lightweight desirable speed reducer of volume for various machinery.
The utility model is achieved in that the cone gear with 90 ° of two reference cone angle convergences, i.e. face gear.The number of teeth difference that makes two gears is one.Be installed in specific forms on two axles of an axis, face gear (3) is installed on the oblique handle of bent axle (1), and face gear (4) is installed on the straight output shaft (2).Make the gearteeth of both ends of the surface gear.Bent axle turns around, and tiltedly handle shakes a circle with bent axle, and tiltedly handle rotates relative to gear (3), tiltedly handle make gear (3) relatively axis swing, and two gears intermesh, and gear (3) is rolled along gear (4).Because two gear differences are one,, promote gear (4) and rotate a tooth again so gear (3) swing once.So just realized deceleration, velocity ratio is the gear ratio one of gear (3).
The advantage of this kind driving mechanism is: one, height is counted in overlapping, can reach the two gear numbers of teeth and 10; Two, slip ratio is little, peak value is the highest is no more than 0.7, this be because: 1, the basic circle line of the involute of involute end face tooth and the position of the bottom line of teeth have been exchanged mutually; 2, the tooth difference of two gears is one; 3, because be the transmissions of intermeshing of two face gears, from equivalents, be that two sizable gears are in the transmission of intermeshing; Three, how much pressure coefficients are little, and at 1.34~1.63, the specific pressure coefficient is little, about 1.20.
When doing the intensity checking computations, take into account contact ratio, only check tired resistance to flexure and get final product, contact strength then needn't check.
This kind driving mechanism possesses above-mentioned advantage, thereby can make bearing capacity height, efficient height, little, the lightweight speed reducer of volume with its technical characteristics, advantage.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Accompanying drawing is the single line sectional view according to the involute end face tooth swinging transmission mechanism that the utility model proposes.
Describe the details and the working condition of the concrete driving mechanism that the utility model proposed in detail below in conjunction with accompanying drawing.
This driving mechanism mainly by: 1, with the bent axle of oblique handle; 2, output shaft; 3, swing face gear; 4, passive face gear; 5, compositions such as block bearing and 6, casing.
A, angle of oscillation c, the pendulum width of cloth that inclines
Bent axle (1) one circle of the oblique handle of rotating band, tiltedly handle shakes a circle thereupon, and tiltedly handle rotates relative to swinging face gear (3), and tiltedly handle makes face gear (3) axis swing relatively.Because of two gear teeth of face gear (3), (4) are intermeshing, face gear (3) is rolled along face gear (4), be one because of two gear teeth differences again, tiltedly handle shakes a circle, make face gear (3) swing one circle, face gear (3) promotes passive face gear (4) and rotates a tooth, has so just realized deceleration, is exported by output shaft.
Claims (1)
- Can be as the speed reducer-involute end face tooth swinging transmission mechanism of various machinery, by the gearteeth transmission of two face gears (3), (4).It is characterized in that:1, the reference cone angle convergence of face gear (3), (4) is 90 °,2, two tooth number differences are one,3, the main axis of output shaft (2), bent axle (1) coexists on the straight line,4, pendulum inclines the width of cloth (C) greater than the addendum of twice,5, the angle of face gear (3) and face gear (4) is that the angle that pivot angle equals between crank spindle line and the oblique arbor line is a cradle angle.
