Description
Technical field
The invention belongs to novel mechanical product technical field, it is related to mechanical basic part pivoting support, and in particular to Yi Zhongshang
Three raceway pivoting supports of the lower step-like bonding crack of circle.
Background technology
Pivoting support is generally nested by inside and outside two steel rings and formed, and between Liang Quan on perpendicular bonding crack, is provided with
Some steel spherical rollers of filling in one tubular raceway of ring-type, raceway（Also known as steel ball）, and separate each rolling
The spacing block of son, additionally, pivoting support is additionally provided with the auxiliary equipment such as filling hole, mounting hole, gear, sealing ring and oil circuit.
, two with footpath raceway can be disposed in parallel in up and down by the ball-type slewing bearing of design and the double raceways of making same diameter
On vertical bonding crack, and upper and lower two filling holes need to be opened up respectively lead to upper and lower raceway, so as to loading roller and spacing block.It is different
The ball-type slewing bearing of the double raceways in footpath, structure is more complex, the three raceways design of intimate prior art.
As for the pivoting support of three raceways, prior art is that inner ring or outer ring that will not set gear are divided into
Lower two-section, using the interlaced setting upper, middle and lower raceway of Internal and external cycle bonding crack, raceway is directly placed in by roller and spacing block
In groove, it is not required to set filling hole again.Completion to be assembled, then be fixed up with that steel ring that silently bolt will be divided into two-section.
A kind of three raceways pivoting support that the present invention is shown, is not required to a segmentation steel ring therein, but change Internal and external cycle
Structure is upper and lower coil structures, a step-like bonding crack is showed between being enclosed upper and lower two, in upper plane, the neutrality of bonding crack
Upper, middle and lower raceway is respectively provided with face and lower plane, a filling hole is only set, and, the mounting hole on upper and lower two circle is that correspondence sets
Put, rather than common inside and outside setting.The present invention is particularly suitable need to correspond to and connects and the main frame of axial load extra-heavy sets up and down
It is standby to use.
The content of the invention
The present invention is a kind of step-like bonding crack using between upper and lower two steel rings, without splitting a steel therein
Enclosing into two-section can just set three extraordinary pivoting supports of raceway, and it is realized by following technical scheme.
A kind of three raceway pivoting supports for enclosing step-like bonding crack up and down, include circle 1, lower circle 2, upper raceway 3, middle rolling
Road 4, lower raceway 5, upper roller 6, middle roller 7, lower roller 8, filling hole 9, internal gear 10, tank filler sleeve 11 and mounting hole 12, it is special
Levy and be：Bonding crack between the upper circle 1 and lower circle 2 is in step-like setting, and rolling is provided with the upper water plane of bonding crack
Road 3, the raceway 4 in the middle part vertical plane of bonding crack is provided with is provided with lower raceway 5, three raceways in the lower horizontal surface of bonding crack
Roll center on the center line of bonding crack；The shape of the upper raceway 3, middle raceway 4 and lower raceway 5, can be all ring-type
Tubular, it is also possible to be all ring-type square-tube-shaped, or middle raceway 4 for ring-type square-tube-shaped, upper raceway 3 and lower raceway 5 are ring-type circle
It is tubular, also, the diameter and the length of side of upper raceway 3, middle raceway 4 and lower raceway 5 are equal, and the angle of square-tube-shaped groove-section is straight
Angle.
A kind of three raceway pivoting supports for enclosing step-like bonding crack up and down, it is characterised in that：The upper roller 6 is seated in
In raceway 3, middle roller 7 is seated in middle raceway 4, and lower roller 8 is seated in lower raceway 5, and each roller is all needed with phase therewith
The spacing block of matching separates, roller bearing steel making, spacing block modification of nylon casting；The upper raceway 3, the and of middle raceway 4
When lower raceway 5 is ring-type tubular, the upper roller 6 of interior middle filling, middle roller 7 and lower roller 8 are spherical roller；The upper raceway
3rd, in middle raceway 4 and lower raceway 5 one or during all ring-type square-tube-shapeds, in square-tube-shaped raceway, diameter can be loaded
Slightly larger than the short cylindrical shape roller of its height, it is also possible to which spherical and two kinds of rollers of short cylindrical shape, also, phase are loaded in mixing in an orderly manner
Two adjacent or close short cylindrical shape rollers must square crossing；The sphere diameter of the upper roller 6, middle roller 7 and lower roller 8 and
Diameter is equal.
A kind of three raceway pivoting supports for enclosing step-like bonding crack up and down, are further characterized in that：The filling hole 9 one sets
The top of lower circle 2, from lateral surface level lead in raceway 4, the aperture of filling hole 9 should be greater than the sphere diameter and diameter of roller so as to
In filling, complete that after loading the blocking of first wife must be stamped and wear pin；The internal gear 10 is located at the medial surface of circle 1, internal gear
10 and the upper surface of pivoting support maintain an equal level, if must the lower surface of internal gear 10 and pivoting support maintain an equal level, pivoting support need to only be fallen
Installation is put, is needed that gear can also be not provided with according to technique；Some of the tank filler sleeve 11, be uniformly located at it is lower circle 2 top, from
Lateral surface level leads to middle raceway 4；Some of the mounting hole 12, is correspondingly arranged at the flange of circle 1 and lower circle 2 respectively
On, the aperture of generally upper lower opening and quantity should be equal；The present invention is not provided with sealing ring.
Beneficial effects of the present invention have：One is that three ring-type raceways have been separately positioned on into two horizontal planes and one is vertical
On the step-like bonding crack of the same in face, the axial load of pivoting support is greatly strengthen, while not influenceing it radially to receive again
The performance of power and tilting moment, the host device of particularly suitable axial high capacity is used；Two is only to be filled by a filling hole
Middle roller and its spacing block are filled out, upper lower roller and its spacing block can directly be laid, without a steel ring therein is divided into
Two-section, will not influence the rigidity and intensity of the steel ring；Three be three raceways and roller can using loading steel ball in tubular raceway,
Also can using filling roller or mixed packing ball, post is intersected in square-tube-shaped raceway, widened the selection space of rolling structure with
The need for meeting different process；Four is that mounting hole of the invention is not common inside and outside setting, but is correspondingly arranged at up and down
On the flange of lower steel ring, the particularly suitable host device for needing Straight to connect is used.
Brief description of the drawings
Fig. 1 is a kind of cross-section structure compares figure of three raceways pivoting support of prior art.
