Description
Technical field
The present invention relates to a kind of thrust block, belong to technical field of bearings.
Background technology
Existing thrust block is divided into thrust ball bearing and thrust roller bearing. Thrust block has small volume, little quality, compact construction, can operate at a high speed and operate steadily, and carries larger axial force and does not bear the features such as radial force, and this just determines that thrust block is applicable to not have radial force and have the high speed of larger axis to power or low speed occasion. Thrust block is divided into blowout patche, seat ring and steel ball-maintenance frame component 3 part structure, and 3 parts are separated from each other, and this just brings bigger limitation for the use of thrust block. Particularly when thrust block is vertically installed and tilts to install, be subject to the comprehensive action of a series of complexcase such as power, running inertia in self gravitation, other associated part gravity and running under, seat ring and steel ball-maintenance frame very easily leave original position, light then cause machine to run well, heavy then cause machine parts to be ruined, cause the accident that comparison is serious.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art part, the present invention provides a kind of more reasonable, safer integral type thrust block.
The present invention is achieved through the following technical solutions: a kind of integral type thrust block, it comprises blowout patche seat and seat ring seat, described blowout patche seat is provided with blowout patche, described seat ring seat is provided with seat ring, steel ball-maintenance frame component is installed between seat ring and blowout patche, described seat ring and the inner ring of blowout patche are equipped with mandrel, mandrel has the two-stage shaft shoulder, described blowout patche is fixedly mounted on the step of first shaft shoulder, described seat ring is movably arranged on the outer ring of the 2nd shaft shoulder, gap is had between the inner ring of seat ring and the cylindrical of mandrel, end at mandrel is manufactured with annular groove, shaft block ring is installed in annular groove, mandrel between shaft block ring and seat ring is equipped with packing ring, described seat ring, steel ball-maintenance frame component, blowout patche, mandrel, packing ring and shaft block ring composition integral type thrust bearing.
Described blowout patche shrink-fit is arranged on described mandrel.
Described blowout patche seat there is spindle nose, described mandrel has the interior hole suitable with described spindle nose.
The invention has the beneficial effects as follows: described seat ring, steel ball-maintenance frame component, blowout patche, mandrel, packing ring and shaft block ring composition integral type thrust bearing, each several part all becomes as a whole in free state or working order and is not separated. Effectively prevent seat ring and steel ball-maintenance frame from leaving original position. Make whole bearing module, it may also be useful to more convenient, safer, not easily produce fault; The same with original thrust block undertake big axial force, do not bear radial force; Whole bearing structure amasss little, can not interfere with original mechanical system, easy for installation.
Accompanying drawing explanation
The present invention is further described according to drawings and embodiments below.
Fig. 1 is present configuration schematic diagram;
Fig. 2 is core shaft structure schematic diagram of the present invention.
In figure, 1, shaft block ring; 2, packing ring; 3, seat ring; 4, steel ball-maintenance frame component;
5, blowout patche; 6, mandrel; 7, blowout patche seat; 8, seat ring seat; 9, spindle nose.
Embodiment
Below in conjunction with embodiment, the present invention is further described.
As shown in Figure 1 and Figure 2, a kind of integral type thrust block, it comprises blowout patche seat 7 and seat ring seat 8, blowout patche seat 7 and seat ring seat 8 have relative movement and have larger axis (namely to have relative movement to the two of power parts in original mechanical system and have larger axis to the two of power parts, because having installed blowout patche and seat ring respectively, so difference called after blowout patche seat 7 and seat ring seat 8). described blowout patche seat 7 is provided with blowout patche 5, described seat ring seat 8 is provided with seat ring 3, steel ball-maintenance frame component 4 is installed between seat ring 3 and blowout patche 5, described seat ring 3 and the inner ring of blowout patche 5 are equipped with mandrel 6, mandrel 6 has the two-stage shaft shoulder, described blowout patche 5 is fixedly mounted on the step of first shaft shoulder, described seat ring 3 is movably arranged on the outer ring of the 2nd shaft shoulder, gap is had between the inner ring of seat ring 3 and the cylindrical of mandrel 6, end at mandrel 6 is manufactured with annular groove, shaft block ring 1 is installed in annular groove, mandrel 6 between shaft block ring 1 and seat ring 3 is equipped with packing ring 2, described seat ring 3, steel ball-maintenance frame component 4, blowout patche 5, mandrel 6, packing ring 2 and shaft block ring 1 form integral type thrust bearing.
Described blowout patche 5 shrink-fit is arranged on described mandrel 6.
Described blowout patche seat 7 there is spindle nose 9, described mandrel 6 has the interior hole suitable with described spindle nose 9.
When whole bearing structure is in free state, blowout patche 5 and mandrel 6 are fixed together running; Packing ring 2 also have with mandrel 6 together with the trend that operates, this just causes packing ring 2 and seat ring 3 to have relatively sliding. Packing ring 2 becomes by grinding two planes after 20CrMnTi carburizing and quenching, highly polished, it is possible to bear the mutual motion of two planes. Transition or slight interference is adopted to coordinate between seat ring 3 and seat ring seat 8, namely without motion mutually between seat ring 3 and seat ring seat 8. When bearing is in strained condition, blowout patche seat 7 transmits axial force to blowout patche 5, keeps frame component 4 and seat ring 3 to be delivered to seat ring seat 8 through steel ball, it is achieved the transmission of axial force of knowing clearly. In the transmittance process of power, together with seat ring 3, steel ball maintenance frame component 4 tightly is pressed in blowout patche 5. Gap is accumulated between packing ring 2 and seat ring 3 completely. Between packing ring 2 and seat ring 3, gap is 0.09-0.4mm, it is possible to run well.In original bearing, blowout patche 5 can be formed with the axle on blowout patche seat 7 and coordinate, and in this Bearning mechanism, if needed, the spindle nose 9 on blowout patche seat 7 can also be formed with the interior hole of mandrel 6 and coordinate, it is not necessary to the installation form changing bearing can meet service requirements.
