Abstract
The utility model discloses an integrated thrust bearing, and belongs to the technical field of bearings. The integrated thrust bearing comprises a blowout patch seat and a bezel seat, wherein the blowout patch seat is provided with a blowout patch; the bezel seat is provided with a bezel; a steel ball-holder assembly is arranged between the bezel and the blowout patch; the inner circles of the bezel and the blowout patch are provided with a mandrel; the blowout patch is fixedly arranged on the mandrel; a clearance is formed between the inner circle of the bezel and the outer circle of the mandrel; a ring groove is formed in the tail end of the mandrel; the ring groove is internally provided with an axial retainer ring; a washer is arranged on the mandrel between the axial retainer ring and the bezel; and the structure of the integrated thrust bearing is formed by the bezel, the steel ball-holder assembly, the blowout patch, the mandrel, the washer and the axial retainer ring. Each part of the integrated thrust bearing disclosed by the utility model is integrated into a whole and non-separation no matter in free state or in working state, prevents the bezel and the steel ball-holder assembly from dislodging effectively, enables the whole bearing to be modularized, and is more convenient and safer to use.
Description
Technical field
The utility model relates to a kind of thrust-bearing, belongs to technical field of bearings.
Background technique
Existing thrust-bearing is divided into thrust ball bearing and thrust roller bearing.Thrust-bearing has small volume, little quality, and compact structure can run up and operate steadily, carrying larger axial force and characteristics such as bearing radial force not, this has larger axis to high speed or the low speed occasion of power with regard to determining thrust-bearing to be applicable to not have radial force.Thrust-bearing is divided into blowout patche, seat ring and steel ball-retainer assembly 3 parts from structure, and 3 parts are separated from each other, and this just brings bigger narrow limitation for the use of thrust-bearing.Particularly when thrust-bearing is vertically installed and tilt to install, under the comprehensive function of self gravitation, other associated part gravity and stressed, a series of complex situations such as running inertia etc. of turning round, seat ring and steel ball-retainer very easily leave original position, gently then cause machine to run well, heavy then cause machine parts to be ruined, cause more serious accident.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art part, the utility model provides a kind of more reasonable, safer integral type thrust-bearing.
The utility model is achieved by the following technical solution: a kind of integral type thrust-bearing, it comprises blowout patche seat and seat ring seat, on the described blowout patche seat blowout patche is installed, on the described seat ring seat seat ring is installed, steel ball-retainer assembly is installed between seat ring and the blowout patche, the inner ring of described seat ring and blowout patche is equipped with mandrel, the two-stage shaft shoulder is arranged on the mandrel, described blowout patche is fixedly mounted on the step of first shaft shoulder, described seat ring is movably arranged on the outer ring of second shaft shoulder, gapped 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 the annular groove, on the mandrel between shaft block ring and the seat ring packing ring is housed, described seat ring, steel ball-retainer assembly, blowout patche, mandrel, packing ring and shaft block ring are formed the integral type thrust bearing.
Described blowout patche interference fit is installed on the described mandrel.
On the described blowout patche seat spindle nose is arranged, the endoporus suitable with described spindle nose arranged on the described mandrel.
The beneficial effects of the utility model are: described seat ring, steel ball-retainer assembly, blowout patche, mandrel, packing ring and shaft block ring are formed the integral type thrust bearing, and each several part still is that working state all becomes as a whole and do not separate in free state.Prevent that effectively seat ring and steel ball-retainer from leaving original position.Make whole bearing modularization, use more conveniently, safer, be difficult for to produce fault; The same big axial force, the not bearing radial force born with original thrust-bearing; Whole bearing structure volume is little, can not interfere with original mechanical system, and is easy for installation.
Description of drawings
With embodiment the utility model is further specified with reference to the accompanying drawings below.
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model mandrel structural representation.
Among the figure, 1, shaft block ring; 2, packing ring; 3, seat ring; 4, steel ball-retainer assembly;
5, blowout patche; 6, mandrel; 7, blowout patche seat; 8, seat ring seat; 9, spindle nose.
Embodiment
Below in conjunction with embodiment the utility model is further specified.
As shown in Figure 1 and Figure 2, a kind of integral type thrust-bearing, it comprises blowout patche seat 7 and seat ring seat 8, blowout patche seat 7 and seat ring seat 8 are relative movement to be arranged and have larger axis (relative movement namely to be arranged in original mechanical system and larger axis is arranged to two parts of power to two parts of power, because blowout patche and seat ring have been installed respectively, so difference called after blowout patche seat 7 and seat ring seat 8).On the described blowout patche seat 7 blowout patche 5 is installed, on the described seat ring seat 8 seat ring 3 is installed, steel ball-retainer assembly 4 is installed between seat ring 3 and the blowout patche 5, the inner ring of described seat ring 3 and blowout patche 5 is equipped with mandrel 6, the two-stage shaft shoulder is arranged on the mandrel 6, 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 second shaft shoulder, gapped between the cylindrical of the inner ring of seat ring 3 and mandrel 6, end at mandrel 6 is manufactured with annular groove, shaft block ring 1 is installed in the annular groove, on the mandrel 6 between shaft block ring 1 and the seat ring 3 packing ring 2 is housed, described seat ring 3, steel ball-retainer assembly 4, blowout patche 5, mandrel 6, packing ring 2 and shaft block ring 1 are formed the integral type thrust bearing.
Described blowout patche 5 interference fit are installed on the described mandrel 6.
On the described blowout patche seat 7 spindle nose 9 is arranged, the endoporus suitable with described spindle nose 9 arranged on the described mandrel 6.
When whole bearing structure is in free state, the running that is fixed together of blowout patche 5 and mandrel 6; Packing ring 2 and mandrel 6 also have the trend of running together, and this just causes packing ring 2 with seat ring 3 relative slip to be arranged.Packing ring 2 by the 20CrMnTi carburizing and quenching after two planes of mill form, highly polished, can bear the mutual motion on two planes.Adopt transition or slight interference to cooperate between seat ring 3 and the seat ring seat 8, namely do not have motion mutually between seat ring 3 and the seat ring seat 8.When bearing was in stress, blowout patche seat 7 transmitted axial forces to blowout patche 5, was delivered to seat ring seat 8 through ball retainer assembly 4 and seat ring 3, the transmission of the axial force that realizes knowing clearly.In the transmittance process of power, seat ring 3, ball retainer assembly 4 and blowout patche 5 are forced together tightly.The gap is accumulated between packing ring 2 and the seat ring 3 fully.The gap is 0.09-0.4mm between packing ring 2 and the seat ring 3, can run well.In original bearing, blowout patche 5 can with blowout patche seat 7 on axle form and to cooperate, in this gear mechanism, if needed, the spindle nose 9 on the blowout patche seat 7 also can cooperate with the endoporus formation of mandrel 6, the installation form that need not to change bearing can satisfy usage requirement.
