Abstract
The invention relates to a production process of a shaft coupler bearing and belongs to the technical field of the technical improvement of the shaft coupler bearing production process. The production process comprises shaft coupler production (1) and bearing installation (2), wherein the shaft coupler production comprises the following steps of barstock preparation; annealing; cold forging; rough turning of end surfaces, outer circles and inner holes; fine turning of inner holes, dustproof grooves and bearing inner ring ditches on the bearing installation surface; heat treatment; end surface grinding; outer circle grinding; ditch grinding on the bearing inner ring ditches by using the bearing inner ring ditches as references; hole grinding on the inner holes by using the bearing inner ring ditches as references; and grinding of the bearing inner ring ditches by using the inner holes as references. The shaft coupler bearing prepared by the production process has the advantages that the concentricity is effectively ensured, the goals of small swinging and low noise during the work of the whole shaft coupler bearing are realized, and in addition, the service life is prolonged. Meanwhile, the shaft coupler bearing is simple and convenient to mount and dismount, and the maintenance is convenient.
Description
Technical field
The present invention relates to a kind of production technology of shaft coupling bearing, belong to the improved technical field of shaft coupling Production of bearing technology.
Background technology
Existing shaft coupling bearing mainly comprises shaft coupling and bearing, and bearing is installed on the bearing installed surface of shaft coupling.Because the difference of processing positioning reference, so there are the problem of decentraction in shaft coupling axle center and bearing installed surface axle center.Simultaneously, the bearing installed surface of shaft coupling and the processing of bearing inner race location also causes shaft coupling axle center and the axle center of bearing can't be concentric not on same benchmark easily, causes the integral coupling bearing when work, rocks greatly, and noise is big, and lack service life.In addition, shaft coupling is selected for use 20GrMo to cast and is made, and has defectives such as material structure is loose, inhomogeneous, there is metallic inclusion inside, pore, and sand holes are arranged in appearance, and service life is short, and lumber recovery is low, and quality cannot say for sure to demonstrate,prove.
The production technology of existing shaft coupling is following: blank → casting → whole cylindrical finish turning → folder peripheral milling bearing installed surface → grinding endoporus.
After shaft coupling machines, steel ball and retainer are installed on its bearing inner race raceway groove and bearing outer ring, last fatten densification sealing obtains finished product.
Summary of the invention
For addressing the above problem, the present invention provides a kind of production technology that realizes the shaft coupling bearing that shaft coupling axle center and BEARING SHAFT are concentric fully.
For realizing above-mentioned purpose, the technical scheme that the present invention adopted is:
A kind of production technology of shaft coupling bearing comprises the steps:
(1) production of shaft coupling;
(2) installation of bearing;
Wherein, The production stage of shaft coupling is: the finish turning → heat treatment → face grinding → cylindrical grinding of the rough turn → cylindrical of bar → annealing → cold forging → end face, cylindrical, endoporus, the bearing inner race raceway groove on the bearing installed surface and dustproof groove, endoporus → with the bearing inner race raceway groove is a benchmark; It is benchmark that the bearing inner race raceway groove is ground ditch (be Zhigou mill ditch) → with the bearing inner race raceway groove; It is benchmark that endoporus is carried out grinding out (being the Zhigou grinding out) → with the endoporus, and the bearing inner race raceway groove is ground.
The present invention directly offers the bearing inner race raceway groove on the bearing installed surface of shaft coupling, realize that promptly bearing inner race raceway groove and bearing installed surface are integrally formed the formula structure, when so bearing being installed, has directly just saved this part of bearing inner race.
Simultaneously, because the fine finishining of bearing inner race raceway groove and the fine finishining of shaft coupling endoporus, all be to be benchmark with the bearing inner race raceway groove, therefore realized the complete concentric purpose of shaft coupling endoporus (being the shaft coupling axle center) and BEARING SHAFT (being the bearing inner race axle center).
As the further setting of such scheme, it is raw material that said shaft coupling is selected mild steel for use, and the surface is carried out carburizing and quenching and handled.
After said shaft coupling machines, on the bearing installed surface of shaft coupling, bearing inner race, bearing outer ring, steel ball and retainer are installed successively, are assembled into existing shaft coupling bearing at last.
Through the shaft coupling bearing that the present invention makes, its concentricity is effectively ensured, has realized that the integral coupling bearing when work, rocks the purpose little, that noise is low, and prolonged service life.Simultaneously, this shaft coupling bearing is installed, dismounting is easy, is convenient to maintenance.
The production technology of a kind of shaft coupling bearing of the present invention, defect rate is low, production efficiency is high, realizes automated production, has simplified production procedure.
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described further.
Description of drawings
Fig. 1 is the structural representation of shaft coupling bearing of the present invention;
Fig. 2 is the structural representation of shaft coupling among the present invention.
The specific embodiment
In conjunction with Fig. 1, shown in Figure 2, the production technology of a kind of shaft coupling bearing of the present invention comprises the steps:
(1) production of shaft coupling;
(2) installation of bearing.
Wherein, The production stage of shaft coupling is: the finish turning → heat treatment → face grinding 1 → cylindrical grinding 2 (adopting 3 centreless mills that become circle) of the rough turn → cylindrical 2 of bar → annealing → cold forging → end face 1, cylindrical 2, endoporus 3, the bearing inner race raceway groove 4 on the bearing installed surface and dustproof groove 5, endoporus 3 → with bearing inner race raceway groove 4 is a benchmark; It is benchmark that bearing inner race raceway groove 4 is ground ditch (be Zhigou mill ditch) → with bearing inner race raceway groove 4; It is benchmark that endoporus 3 is carried out grinding out (being the Zhigou grinding out) → with endoporus 3, and bearing inner race raceway groove 4 is ground.
It is raw material that above-mentioned shaft coupling is selected mild steel for use.
After shaft coupling machines, steel ball 6 and retainer 7 are installed on its bearing inner race raceway groove 4 and bearing outer ring 8, last fatten densification sealing obtains finished product.
The foregoing description only is used to the inventive concept of the present invention of explaining, but not to the qualification of rights protection of the present invention, allly utilizes this design that the present invention is carried out the change of unsubstantiality, all should fall into protection scope of the present invention.
