Abstract
The invention discloses a lubrication fulcrum enabling a bearing super-finishing machine to eliminate fulcrum marks. The lubrication fulcrum achieves the purpose that no fulcrum mark is generated after sleeve ring machining. According to the technical scheme, the fulcrum arc surface (2) of the lubrication fulcrum (1) is matched with the outer diameter of a sleeve ring (4) after being coarsely and finely ground, the fulcrum arc surface (2) is provided with a plurality of lubrication oil holes (3), an electromagnetic valve (7) and a hydraulic station II (8) are arranged on the super-finishing machine to form a fulcrum lubrication pipeline, super-finishing oil of the hydraulic station II (8) is controlled by the electromagnetic valve (7) to pass through a hydraulic station I (5) through a pipe connector (6) to enter the lubrication oil holes (3) and is injected with a certain pressure, and a moving and static oil pressing film is formed between the sleeve ring (4) and the fulcrum arc surface (2). The lubrication fulcrum enabling the bearing super-finishing machine to eliminate the fulcrum marks has the advantages that the oil film with the certain thickness is formed between the sleeve ring and the fulcrum arc surface, friction is hardly generated, no fulcrum mark is generated after sleeve ring machining, the appearance quality of a bearing is ensured, a working procedure of grinding the fulcrum marks is omitted, and manufacturing cost of the bearing is greatly reduced.
Description
Technical field
The present invention relates to bearing ring tool for processing, be specifically related to a kind of bearing Superfinishing machine and eliminate the lubricated fulcrum that fulcrum prints, the lasso after processing does not have the lubricated fulcrum that fulcrum prints.
Background technology
Bearing outer ring Superfinishing machine processing great majority are with end face and external diameter location, and during ditch (rolling) road superfinishing, end face compresses with pinch roller, and two fulcrums prop up on external diameter.Lasso work in-process rotates with fulcrum cambered surface and belongs to sliding friction, after superfinishing, on ferrule supports surface, leaves ring-type vestige, is commonly called as fulcrum and prints, and bearing outside diameter and fulcrum surface roughness value are larger, and fulcrum prints more serious, directly affects bearing presentation quality.In order to eliminate ring-type vestige, after microstoning finishes, have to increase and remove together the grinding program that fulcrum prints.Not only increased the manufacturing cost of bearing, extended the process-cycle and destroyed original machining accuracy.
Summary of the invention
The present invention discloses a kind of bearing Superfinishing machine and eliminates the lubricated fulcrum that fulcrum prints, and lubricated fulcrum arc surface with certain pressure oil spout, can form one deck dynamic and static pressure oil film by oilhole between lasso external diameter and fulcrum arc surface, does not produce fulcrum and print after lasso processing.
In order to achieve the above object, adopt following technical scheme.
Lubricated fulcrum fulcrum arc surface is (1) (2) by after twice grinding of thickness, (4) external diameter is identical with lasso, and (3) (2) fulcrum arc surface be provided with some oilholes; (7) Superfinishing machine configures magnetic valve and (8) Hydraulic Station II forms fulcrum lubricating pipe, and (3) (5) (6) fulcrum lubricating pipe be connected to oilhole by Hydraulic Station I by pipe joint.
The invention has the advantages that: on fulcrum arc surface, be designed with some oilholes, between lasso and fulcrum arc surface, form certain thickness oil film, produce hardly friction, lasso does not produce fulcrum and prints after processing, bearing presentation quality is guaranteed, and reduced the operation of one reconditioning fulcrum seal, greatly reduced the manufacturing cost of bearing.
Accompanying drawing explanation
Fig. 1 is the lubricated fulcrum structure schematic diagram of the present invention;
Fig. 2 is lubricant passage way schematic diagram.
Illustration: lubricated fulcrum 1, fulcrum arc surface 2, oilhole 3, lasso 4, Hydraulic Station I 5, pipe joint 6, magnetic valve 7, Hydraulic Station II 8.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described with concrete real mode.
As shown in Figure 1, fulcrum arc surface 2 materials of lubricated fulcrum 1 are Hardmetal materials, and by coincideing with lasso 4 external diameters after twice grinding of thickness, fulcrum arc surface 2 is provided with some oilholes 3 and is connected with Hydraulic Station I 5.
As shown in Figure 2, Superfinishing machine configuration magnetic valve 7 and Hydraulic Station II 8 form fulcrum lubricating pipe, and fulcrum lubricating pipe is connected to oilhole 3 by pipe joint 6 by Hydraulic Station I 5.
Lasso 4 is placed on lubricated fulcrum 1, and lasso 4 external diameters and fulcrum arc surface 2 coincide, and lasso 4 rotates with certain revolution; Start Hydraulic Station II 8, superfinishing oil is under magnetic valve 7 is controlled, through pipe joint 6, by Hydraulic Station I 5, enter into oilhole 3 with certain pressure oil spout, at lasso 4 and 2 of lubricated fulcrum arc surfaces, form dynamic and static pressure oil film, pressure can be regulated by Hydraulic Station II 8 as required, and oil film thickness is corresponding change thereupon.Lasso 4 has oil film to exist with fulcrum arc surface 2, and lasso 4 does not directly contact with fulcrum arc surface 2, produces hardly friction, and lasso 4 can not produce fulcrum and print after processing.
Claims (3)
1. bearing Superfinishing machine is eliminated the lubricated fulcrum that fulcrum prints, and it is characterized in that: described lubricated fulcrum fulcrum arc surface is (1) (2) by after twice grinding of thickness, (4) external diameter is identical with lasso, and (3) (2) fulcrum arc surface be provided with some oilholes.
2. a kind of bearing Superfinishing machine is eliminated the lubricated fulcrum that fulcrum prints according to claim 1, it is characterized in that: (6) (5) (3) described oilhole be connected to fulcrum lubricating pipe by pipe joint by Hydraulic Station I.
