Description

The adjustable phase gear-box
Technical field
The utility model relates to a kind of gear-box, relates to a kind of adjustable phase gear-box specifically.This gear-box is realized by introduce differential attachment in gear-box, and by the rotation of worm gear pair drive differential planetary frame, is produced certain phase difference thereby make between input shaft and the output shaft.
Background technique
Steel mill's continuous casting is compared with common steel ingot casting, has the increase recovery rate of iron, and energy saving improves slab quality, is convenient to realize advantages such as mechanization, automation.This technology is used widely in steel mill at present.The main effect of crystallizer in continuous casting is once to cool off.Simultaneously even in order to guarantee discharging, reduce throwing frictional force, avoid molten steel glue wall, bleed-out and improve steel billet inherent quality and surface quality, also to drive crystallizer and press certain waveform rule up-down vibration by a vibrating mechanism.For realizing this purpose, be extensive use of direct current generator or alternating-current variable frequency motor and drive double rocker mechanism realization mold oscillation by eccentric cam.Under existing conditions of manufacture, keep strokes for making double rocking lever, need frequent manual adjustment coupling that phase place is installed, very inconvenient.
For solving above-mentioned this technical problem, find after deliberation, if can design a kind of adjustable phase gear-box that produces certain phase difference between input shaft and the output shaft that makes, just can reach the purpose of adjusting the rocking bar position by the phase difference of two between centers.And the solution of this technology can be by introducing differential attachment in gear-box---the design principle that is automobile differential realizes.
The kinematic relation of each element in the automobile differential of prior art---differential principle can illustrate by shown in Figure 1.The symmetric type bevel differential is a kind of planetary gears.Differential carrier 3 fuses with planet pin 5, and planet carrier is a driving link, and establishing its angular velocity is ω 0; Differential gear 1 and 2 is a driven member, and its angular velocity is ω 1 and ω 2.2 of A, B are respectively planetary pinion 4 and two-semiaxle gear meshing point.Planetary central point is C, and A, B, C point are r to the distance of differential mechanism spin axis.When planetary pinion just in company with planet carrier when the differential mechanism spin axis revolve round the sun, obviously, the peripheral velocity that is in A, B, C on the same radius r at 3 all equates (Fig. 1 b), it is worth is ω 0r.So ω 1=ω 2=ω 0, promptly differential mechanism does not play differential action, and two-semiaxle angular velocity equals the angular velocity of differential carrier 3.When planetary pinion except that revolution, also around axle itself 5 with angular velocity omega A time rotational (Fig. 1 c), the peripheral velocity of contact points A is ω 1r=ω 0r+ ω ArA, the peripheral velocity of contact points B is ω 2r=ω 0r-ω ArA.
So ω 1r+ ω 2r=(ω 0r+ ω ArA)+(ω 0r-ω ArA)
Be ω 1+ ω 2=2 ω 0
Represent with rpm n as if angular velocity, then n 1+ n 2=2n 0
This is the kinetic characteristic equation of the equal symmetric type bevel differential of two-semiaxle gear diameter.It shows that the rotating speed sum of left and right sides differential gear equals the twice of differential carrier rotating speed, and irrelevant with the planetary pinion rotating speed.Therefore, automobile turning travel or other travel situations under, can borrow planetary pinion with corresponding rotating speed rotation, make the both sides driving wheel roll on the ground and not slide with different rotating speeds.
Summary of the invention
The purpose of this utility model just is being based on above-mentioned design principle and a kind of adjustable phase gear-box that produces certain phase difference between input shaft and the output shaft that makes is being provided, and reaches the purpose of adjusting the rocking bar position by the phase difference of two between centers.
The purpose of this utility model can realize by following technique measures:
Adjustable phase gear-box of the present utility model is divided into the two-stage transmission, and wherein the one-level transmission drives intermeshing one-level input bevel gear, two semiaxis bevel planet gears and one-level output bevel gear by input shaft and planet carrier is formed differential attachment together; The secondary transmission is formed by a pair of awl tooth is secondary; Wherein the output bevel gear of the input bevel gear of secondary transmission and one-level transmission is installed on the output shaft of one-level transmission with coaxial manner; Be provided with a worm couple between the output bevel gear of the input bevel gear of secondary transmission and one-level transmission, the worm gear in the described worm couple is installed on the output shaft of one-level transmission in mode movingly, and with the planet carrier Joint.
Working principle of the present utility model is as follows:
Coupling controlling mechanism during the vibrating mechanism of gear-box of the present utility model and crystallizer driven combines, inconsistent in the double rocking lever action, need to adjust coupling phase place is installed, start gear-box of the present utility model, driving the input bevel gear by input shaft rotates, and, be passed to one-level output bevel gear by two semi-axle bevel gears, at last by the output of next stage bevel gear pair.When the worm gear that is fixed together with planet carrier rotated under worm drive, planet carrier also rotated thereupon.When keeping one-level input bevel gear motionless, the both rotations of semiaxis bevel planet gear, revolve round the sun with planet carrier again, and driving one-level output bevel gear is rotated, thereby realize the phase difference between input shaft and the output shaft, promptly under input shaft keeps motionless situation, output shaft still can rotate in certain speed range under the driving of worm and gear, when treating to adjust to the right place in the rocking bar position, the auto-lock function of worm and gear transmission can make this fixed-site, and then reach the purpose of adjusting the rocking bar position, double rocking lever is kept strokes.
The beneficial effects of the utility model are as follows:
The alternative traditional manual adjustment coupling of the utility model is installed phase place and is realized the adjustment mode that double rocking lever is kept strokes, not only shake and provide convenience for the adjustment of double rocking lever position, the vibrational waveform that main is can make crystallizer is stable and consistent more, even in order to guarantee discharging, reduce throwing frictional force, avoid molten steel to glue wall, bleed-out and improve the steel billet inherent quality and surface quality provides advantageous conditions more.
