Embodiment
Core of the present utility model provides a kind of fitting seat of rotary reducer, this fitting seat is used for the rotary reducer of engineering machinery swirl gear is fixed on the turntable base plate, can make described swirl gear under the situation of setting-up eccentricity or non-eccentricity formula rotary reducer, can both regulate the Gear center distance of swirl gear.
Second core of the present utility model provides a kind of engineering machinery that comprises above-mentioned fitting seat.
In order to make those skilled in the art person understand the utility model scheme better, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 2, Fig. 3, Fig. 2 surveys schematic representation for the axle of a kind of embodiment of fitting seat of rotary reducer that the utility model provides; Fig. 3 is the schematic top plan view of the fitting seat of rotary reducer shown in Figure 2.
The fitting seat 100 of the rotary reducer that this embodiment provided is does not have the flange plate of neck shape, its endoporus center of circle is in the eccentric position of fitting seat, card is provided with the outer ring attachment hole 103 of a circle near the outer, these outer ring attachment holes 103 are through hole, along the circumferential direction the mode with annular array evenly distributes, also be provided with the inner ring attachment hole 104 of a circle on the card near the endoporus edge, these inner ring attachment holes 104 are blind hole, evenly distribute along the circumferencial direction of endoporus mode with annular array, because the endoporus center of circle is in the eccentric position of fitting seat, so the annular array center of inner ring attachment hole 104 also is in eccentric position with respect to the annular array center of outer ring attachment hole 103.
Please refer to Fig. 4, Fig. 4 is the schematic diagram that utilizes the fitting seat adjusting gear centre distance of rotary reducer shown in Figure 2.
When the assembling rotary reducer, rotary reducer 200 is connected by bolt with the inner ring attachment hole of fitting seat 100, the turntable base plate is connected by bolt with the outer ring attachment hole of fitting seat 100, the Gear center O of rotary reducer and the annular array center of inner ring attachment hole overlap, and whole rotary reducer 200 is positioned at the eccentric position of fitting seat.
Because in, the annular array center of outer two circle attachment holes has a throw of eccentric, when installing to rotary reducer 200 on the turntable base plate, can make the annular array center O ' rotation of the Gear center O of rotary reducer by rotating fitting seat 100 round the outer ring attachment hole, form a circus movement track, shown in the dotted line small circle, any point on the trajectory and gyration center O " line be the Gear center distance; because the difference on the trajectory is to gyration center O " distance difference, therefore can realize adjusting to the Gear center distance, that is to say, can be that the rotary reducer of non-eccentricity formula becomes eccentric speed reducer with self structure by fitting seat 100.
Like this, can make swirl gear under the situation of setting-up eccentricity or non-eccentricity formula rotary reducer, can both regulate the Gear center distance of swirl gear, can reduce back lash between gear by adjusting gear centre distance, and then reduce inertia impact, make the motion of swirl gear steady more, reliable, guarantee job safety.
Certainly, above-mentioned inner ring attachment hole 104 and outer ring attachment hole 103 are not limited to the quantity shown in the figure, can further increase or reduce according to the size of fitting seat and the factors such as requirement of join strength.
If the outer ring attachment hole is corresponding one by one with attachment hole on the turntable base plate, when rotating fitting seat, its minimum angles that can rotate is relevant with the quantity of outer ring attachment hole, the quantity of outer ring attachment hole is many more, the minimum angle of swing that is allowed is just more little, if the quantity of outer ring attachment hole is n, so minimum angle of swing just equals 360 °/n, and angle of swing is more little, under the identical condition of throw of eccentric, the variable quantity of above-mentioned centre distance is just more little, and therefore a fairly large number of outer ring attachment hole will help to improve the degree of regulation of centre distance.Because the card space of fitting seat is limited, and too intensive attachment hole can reduce the intensity of fitting seat, therefore the quantity of outer ring attachment hole is controlled at 12-24 comparatively suitable.
When regulating centre distance by the rotation fitting seat, its regulation range is relevant with the throw of eccentric at inner ring attachment hole annular array center, and the centre distance of establishing under the normal condition is L, if the throw of eccentric at inner ring attachment hole annular array center is Δ L on the fitting seat, so, when the rotation fitting seat was regulated, Gear center can transfer to L+ Δ L apart from maximum, minimum can transfer to L-Δ L, its regulation range is (L+ Δ L)-(L-Δ L), and promptly 2 * Δ L is obvious, L is big more for its throw of eccentric Δ, and regulation range is also big more.
In addition, above-mentioned throw of eccentric Δ L is also relevant with degree of regulation, under the identical situation of angle of swing, the throw of eccentric Δ L at inner ring attachment hole annular array center is big more, and the variable quantity of centre distance is just big more, and degree of regulation is relatively low, otherwise, L is more little for the throw of eccentric Δ, and the variable quantity of centre distance is just more little, and degree of regulation is higher relatively.
If above-mentioned throw of eccentric Δ L is too small, can't satisfy and regulate required side-play amount, if the throw of eccentric Δ L of fitting seat is excessive, not only can exceeds and regulate required side-play amount, and can cause degree of regulation to descend.Because the variation of Gear center distance mainly causes because of wearing and tearing, according to the greatest wear amount that gear may occur, above-mentioned throw of eccentric Δ L can be set between the 0.1mm-10mm, preferably, can be set between the 2mm-8mm, to avoid occurring the excessive or too small situation of throw of eccentric.
Outer ring attachment hole 103 in the above-mentioned embodiment and inner ring attachment hole 104 are on the same plane of fitting seat, because the annular array center of inner ring attachment hole 104 is in eccentric position, therefore the outer ring attachment hole 103 of fitting seat one side is less with inner ring attachment hole 104 spacings, and the spacing of opposite side is bigger, during installation, the phenomenon of interference mutually may appear in the less side of spacing, for this reason, can suitably increase the diameter of fitting seat, keep suitable spacing to guarantee inside and outside two circle attachment holes.But can cause the fitting seat size to become big like this, under the condition of limited of structural design space, be difficult to realize.
