Abstract
The present invention discloses the soft ribbons method for curing of a kind of three-row roller turntable bearing, the raceway of three-row roller turntable bearing is straight raceway, first the width of soft ribbons part on raceway is determined, then the soft ribbons part of raceway is dug the shape that is in depression, finally use ceramic dielectric depression to be filled and led up, and it is consistent with the hardness of hardened face on raceway to control the case hardness after ceramic dielectric is filled.The method that the present invention provides makes raceway hardness consistent, is not limited by installation site, for the most full hardened steel and carburizing steel, is greatly saved processing cost.When the present invention solves difference of hardness by the way of eliminating difference of hardness, the material of linking part can be extruded raceway, form the irregularly shaped projection of warty, when other rollers are through this projection, friction can be increased, increase energy consumption, the problem that Bearing inner premature wear even damages can be made simultaneously.
Description
Technical field
The invention belongs to turntable bearing technical field, be specifically related to the soft ribbons hardening side of a kind of three-row roller turntable bearing
Method.
Background technology
The Internal and external cycle of three-row roller turntable bearing typically uses 42crmo material, when carrying out surface high frequency quenching, and can shape
Become one section of soft ribbons.Soft ribbons case hardness is material matrix hardness 229-300HB, and hardened face hardness can reach more than 45HRC, by
Exist in this difference of hardness, when bearing big load effect, when roller is through soft ribbons and the timesharing of hardened face convergence part, convergence part
The material divided can be extruded raceway, forms the irregularly shaped projection of warty, when other rollers are through this projection, can increase and rub
Wipe, increase energy consumption, Bearing inner premature wear can be made simultaneously even to damage.It addition, for some use occasion, it is desirable to axle
Holding without soft ribbons, normal conditions can select full hardened steel or carburizing steel, it is contemplated that the hole machined of turntable bearing and tooth processing, uses
Both materials can be greatly increased processing cost.
Summary of the invention
For solving above-mentioned technical problem, the present invention provides the soft ribbons method for curing of a kind of three-row roller turntable bearing, the party
Method makes raceway hardness consistent, is not limited by installation site, for the most full hardened steel and carburizing steel, significantly saves
Save processing cost.
The technical solution adopted in the present invention is: the soft ribbons method for curing of a kind of three-row roller turntable bearing, three-row roller
The raceway of turntable bearing is straight raceway, it is first determined the width of soft ribbons part on raceway, then the soft ribbons part of raceway is dug
Be in depression shape, finally uses ceramic dielectric depression to be filled and led up, and controls the case hardness after ceramic dielectric is filled and raceway up-quenching
The hardness in energy meter face is consistent.
As the further optimization of the soft ribbons method for curing of the present invention a kind of three-row roller turntable bearing, described ceramic dielectric
Prepared through mixing post-heating molding by pottery and intermixture.
As the further optimization of the soft ribbons method for curing of the present invention a kind of three-row roller turntable bearing, described employing pottery
Medium fills and leads up the detailed process of depression: is filled in recess after pottery and intermixture being mixed, is then locally heated to mixing
Agent is fully melted, and arranges flatness, and natural cooling i.e. completes.
As the further optimization of the soft ribbons method for curing of the present invention a kind of three-row roller turntable bearing, described pottery is powder
The silicon nitride material of powder.
As the further optimization of the soft ribbons method for curing of the present invention a kind of three-row roller turntable bearing, described intermixture
PVC material for powder.
As the further optimization of the soft ribbons method for curing of the present invention a kind of three-row roller turntable bearing, described depression deep
The degree roller diameter more than 0.05 times.
Compared with prior art, the present invention at least has and has the advantage that and beneficial effect:
The method that the present invention provides makes raceway hardness consistent, is not limited by installation site, the most full hardened steel
For carburizing steel, it is greatly saved processing cost.The rank when present invention has solved difference of hardness by the way of eliminating difference of hardness
The material connecing part can be extruded raceway, forms the irregularly shaped projection of warty, when other rollers are through this projection, can increase
Friction, increases energy consumption, can make the problem that Bearing inner premature wear even damages simultaneously.
Accompanying drawing explanation
Fig. 1 is soft ribbons of the present invention hardening schematic diagram；
Reference: 1, the soft ribbons surface after hardening, 2, raceway hardened face, 3, ceramic dielectric.
Detailed description of the invention
For making present disclosure become apparent, below in conjunction with specific embodiment, describe the present invention.
As it can be seen, the soft ribbons method for curing of a kind of three-row roller turntable bearing, the raceway of three-row roller turntable bearing is
Straight raceway, it is first determined the width of soft ribbons part on raceway, then digs, by the soft ribbons part of raceway, the shape that is in depression, finally uses
Depression is filled and led up by ceramic dielectric, and it is consistent with the hardness of hardened face on raceway to control the case hardness after ceramic dielectric is filled.
In order to make the present invention have more preferable implementation result, described ceramic dielectric is added after mixing by pottery and intermixture
Thermoforming prepares.The degree of depth of the described depression roller diameter more than 0.05 times, uses ceramic dielectric to fill and lead up the detailed process of depression
For: it is filled in recess after pottery and intermixture being mixed, is then locally heated to intermixture and fully melts, then use local mill
The mode of cutting arranges flatness, and natural cooling i.e. completes.
As further optimal way, described pottery is the silicon nitride material of powder, and described intermixture is powder
The PVC material of powder.The hardness on ceramic dielectric surface is exactly the hardness of soft ribbons position, ceramic hardness can by regulation pottery and
The ratio of intermixture is controlled so that ceramic dielectric hardness is consistent with raceway hardness, eliminates the need for soft ribbons, it is achieved that soft ribbons is hard
Change.
The method that the present invention provides makes raceway hardness consistent, is not limited by installation site, the most entirely quenches simultaneously
For fire steel and carburizing steel, it is greatly saved processing cost.The present invention has solved difference of hardness by the way of eliminating difference of hardness
Time linking part material can be extruded raceway, form the irregularly shaped projection of warty, when other rollers are through this projection, meeting
Increase friction, increase energy consumption, the problem that Bearing inner premature wear even damages can be made simultaneously.
