Abstract

The invention 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 a blowout patch is arranged on the blowout patch seat, a bezel is arranged on the bezel seat, and a steel ball-holder assembly is arranged between the bezel and the blowout patch; a mandrel is arranged on the inner circles of the bezel and the blowout patch, the blowout patch is fixedly arranged on the mandrel, and space is formed between the inner circle of the bezel and the outer circle of the mandrel; a ring groove is arranged at the end of the mandrel, an axial retainer ring is arranged in the ring groove, and 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 invention 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 more safe to use.

Description

The integral type thrust-bearing
Technical field
The present invention relates to a kind of thrust-bearing, belong 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 just determines that thrust-bearing is applicable to there is no radial force and larger axis is arranged to high speed or the low speed occasion of power.Thrust-bearing is divided into blowout patche, seat ring and steel ball-holder assembly 3 parts from structure, and 3 parts are separated from each other, and this just brings larger 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, the series of complex situations such as running inertia etc. of turning round, seat ring and steel ball-holder very easily leave original position, gently cause machine to run well, heavy 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 invention provides a kind of more reasonable, safer integral type thrust-bearing.
the present invention is achieved through the following technical solutions: a kind of integral type thrust-bearing, it comprises blowout patche seat and seat ring seat, on described blowout patche seat, blowout patche is installed, on described seat ring seat, seat ring is installed, the steel ball-holder assembly is installed between seat ring and blowout patche, the inner ring of described seat ring and blowout patche is equipped with mandrel, the two-stage shaft shoulder is arranged on 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 annular groove, on mandrel between shaft block ring and seat ring, packing ring is housed, described seat ring, the steel ball-holder assembly, blowout patche, mandrel, packing ring and shaft block ring form the integral type thrust bearing.
Described blowout patche interference fit is arranged on described mandrel.
On described blowout patche seat, spindle nose is arranged, the endoporus suitable with described spindle nose arranged on described mandrel.
The invention has the beneficial effects as follows: described seat ring, steel ball-holder assembly, blowout patche, mandrel, packing ring and shaft block ring form the integral type thrust bearing, and each several part all becomes as a whole in free state or working state not to be separated.Prevent that effectively seat ring and steel ball-holder from leaving original position.Make whole bearing module, use more conveniently, safer, be difficult for to produce fault; Bear large axial force, not bearing radial force the same as original thrust-bearing; Whole bearing structure volume is little, can not interfere with original mechanical system, and is easy for installation.
Description of drawings
The present invention is further described according to drawings and embodiments for the below.
Fig. 1 is structural representation of the present invention;
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-holder assembly;
5, blowout patche; 6, mandrel; 7, blowout patche seat; 8, seat ring seat; 9, spindle nose.
Embodiment
The present invention is further described below in conjunction with embodiment.
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 described blowout patche seat 7, blowout patche 5 is installed, on described seat ring seat 8, seat ring 3 is installed, between seat ring 3 and blowout patche 5, steel ball-holder assembly 4 is installed, 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 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 annular groove, on mandrel 6 between shaft block ring 1 and seat ring 3, packing ring 2 is housed, described seat ring 3, steel ball-holder assembly 4, blowout patche 5, mandrel 6, packing ring 2 and shaft block ring 1 form the integral type thrust bearing.
Described blowout patche 5 interference fit are arranged on described mandrel 6.
On described blowout patche seat 7, spindle nose 9 is arranged, the endoporus suitable with described spindle nose 9 arranged on 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 and seat ring 3 that relative sliding is arranged.Packing ring 2 by the 20CrMnTi carburizing and quenching after mill two planes form, highly polished, can bear the mutual motion on two planes.Adopt transition or slight interference to coordinate between seat ring 3 and seat ring seat 8, namely move without mutual between seat ring 3 and 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 seat ring 3 fully.Packing ring 2 and seat ring 3 gaps are 0.09-0.4mm, can run well.In original bearing, blowout patche 5 can with blowout patche seat 7 on axle form and to coordinate, in this gear mechanism, if needed, the spindle nose 9 on blowout patche seat 7 also can coordinate with the endoporus formation of mandrel 6, the installation form that need not to change bearing can satisfy usage requirement.
