Abstract
The invention relates to a planetary wheel type exciter of a vertical vibratory road roller, using two planetary wheel type coaxial constant-speed inverse operating mechanisms to enable four eccentricblocks at the same axis to run inversely in pairs so as to offset the vibration and twisting in the horizontal direction and realize vertical and single vibration. In assembly, the planetary wheel type coaxial constant-speed inverse operating mechanisms at the core part are assembled inside a vibratory wheel in a form of a part for convenient assembly and maintenance. With high universality, theexciter can directly replace a common exciter of a vibratory road roller and can realize efficient vertical vibration without changing an external hydraulic system and a machine structure.
Description
Technical field
Patent of the present invention belongs to mechanical engineering technical field, realizes the antiport of coaxial constant speed with planetary gear, realizes vertical vibration.
Background technology
The vibrator of present domestic vibratory roller vibratory chamber inside is divided into two kinds of eccentric rod-type and eccentric wheel types, relies on eccentric rod or eccentric rotation to produce the eccentric force vibration.This mode of vibration is the synthetic of horizontal vibration and vertical vibration.
Its shortcoming is:
1. horizontal vibration has been disturbed effective vibration of vertical vibration, and vibration is unordered, chaotic, and consolidation effect is bad;
2. level makes that with the complex vibration of vertical both direction the vibrating wheels vibration is chaotic, increases the fatigue strength of human pilot, has increased the dangerous coefficient of body.
The present vertical vibration roller of domestic-developed mostly adopts the antiport same period of two eccentric shafts, with this offset by the level of vibration, realizes vertical vibration.The shortcoming of this type of vertical vibration vibrator is: exciting force is less, its good with shake and can only regulate for a short time by rotating speed, amplitude and exciting force scope are little.
Summary of the invention
The innovative point of patent of the present invention: utilize planetary gear to realize coaxial constant speed antiport.When the vibrating wheels that is applied in road roller is inner, can be so that four eccentric block reverse rotations in twos on axis with this offset by the level of vibration, realize vertical vibration.Its advantage is that under same input angular velocity value, the change rotation direction can realize large and small transformation of shaking.
Set forth the core position of patent of the present invention below: coaxial constant speed antiport mechanism.Mechanism principle figure such as Fig. 1.
Figure 1 shows that coaxial constant speed antiport mechanism principle figure.Its function that can realize is: the sun gear center of the sun gear of I planetary gear and II planetary gear on an axis, rotating speed equates, direction of rotation.
1. directionality:
As Fig. 2.
Planetary gear set (I, II planetary gear and claim, below all claim " planetary gear set ") the transmission of power direction as follows:
2. speed:
The gearratio of given row star-wheel is the outer ring gear ratio sun gear number of teeth.If the outer ring number of teeth of I planetary gear is i with sun gear number of teeth ratio
1, the outer ring number of teeth of II planetary gear is i with sun gear number of teeth ratio
2Then, the gearratio of I planetary gear is
The gearratio of II planetary gear is i
2For the input angular velocity that guarantees planet circular system equates that with the output angle velocity amplitude following formula is arranged:
Conclusion: satisfy i when two of this cover planet circular system transmission mechanism overlaps planetary gear gearratios relation
2=1+i
1The time, can realize the motion state that coaxial constant speed is reverse.
We are applied to this planetary gear set in the vibrating wheels of road roller, just can realize vertical vibration.As Fig. 3, be vertical vibration roller vibrating wheels schematic diagram.
Among Fig. 3,1. quantitative piston motor, 2. rubber damping piece, 3. eccentric block, the 4. coaxial constant speed antiport of planet gear type mechanism, the 5. steel wheel of vertical vibration wheel.
Description of drawings
Fig. 1 is the coaxial constant speed antiport of a planetary gear mechanism.
Fig. 2 is the checking of the coaxial constant speed direction of planetary gear works directionality.
Fig. 3 is a vertical vibration roller vibrating wheels schematic diagram.
During concrete enforcement, two cover planetary gears of the coaxial constant speed antiport of planet gear type mechanism are made parts be installed in vibratory chamber inside, with convenient for assembly, maintenance and maintenance.According to the general assembling mode of planetary gear, the star-wheel of I planetary gear is embedded into the inside, outer ring of II planetary gear, the star-wheel of II planetary gear is embedded on the shell body, to guarantee the stability of all star-wheels motions.The outer ring of II planetary gear is fixed on the shell body of the right and left by two pairs of taper roll bearings, to guarantee its stability.The gear backlash of star-wheel and sun gear also can guarantee thus.
The power of vibrating wheels is provided by the quantitative piston motor in left side, and the direction of motion of four eccentric blocks is positive and negative, instead, just, comes the vibration of offset by the level of direction with this, to the vibration amplification of vertical direction.And adopt four eccentric blocks, and also can prevent the twisting of vibrating wheels effectively, make vibration steadily.Under same rotating speed, four eccentric blocks are that symmetry is installed, and the motor counter-rotating can realize large and small conversion of shaking.
By Fig. 3, we can see, about two vibratory chamber be connected with body by bolt, (totally 4 on left side, centre, right side) steel wheel can roll by self-aligning roller bearing relatively with vibratory chamber.That is to say that when the road roller operate as normal, vibratory chamber is connected with body by damping block with bolt, steel wheel rolls to operative orientation under the effect of frictional ground force.Vibratory chamber does not roll with steel wheel, is the angular error of four eccentric blocks causing for the movement warp of eliminating by planetary gear set and eccentric block, has guaranteed the vertical unicity of vibrating.
