Abrasive material of woven fabric, another abrasive material of industrial scouring pad material, a pair of anti-lint protection rings are respectively sleeved on the outer edges of the two abrasive materials, and the two abrasive materials and the middle substrate are pressed and fixed. The abrasive disc can be repaired by selecting abrasives of different materials on both sides for different defects on the tile surface, and can better meet the high requirements for babbitt alloy repair.

Description

The bearing tile surface is repaired and is used abrasive disc

Technical field

The utility model relates to abrasive disc, more particularly, relates to a kind of bearing tile surface reparation abrasive disc.

Background technology

The surface that oil film contacts between the tile fragment front of tile fragment formula thrust bearing and thrust disc is coated with the babbit of one deck 1.2mm, and smooth, the whole group tile fragment of its surface requirements must keep the thickness unanimity.Yet when the operation of thrust bearing through a period of time, because the influence of all kinds of factors, smooth tile fragment babbit face can produce point-like with the contact-making surface between thrust disc and contact problems such as bright spot (being the sintering hard spot), cut and babbit face adhesion sheet grease, directly has influence on the use of thrust bearing.At above-mentioned situation, must in time repair tile fragment.Because this tile fragment material is comparatively special, some common abrasive discs can not be applicable to the reparation on babbit surface preferably.At present, normally do to scrap processing, also just adopt scraper by the method for scraping and the polishing of fine sand skin cut and grease to be repaired one by one at most, but be difficult to guarantee smooth, the flatness on tile fragment surface and the thickness unanimity of whole group tile fragment like this, tile fragment utilization rate after causing repairing is very low, and effect is also poor.

The utility model content

At the above-mentioned shortcoming that exists in the prior art, the purpose of this utility model provides the surface reparation of a kind of bearing tile and uses abrasive disc, helps the reparation to the various defectives of tile fragment surface babbit.

For achieving the above object, the utility model adopts following technical scheme:

This bearing tile surface is repaired with abrasive disc and is comprised hard Intermediate substrate, mild abrasives and anti-hair guard circle; two abrasive materials are located at the two sides of Intermediate substrate respectively; a slice is the abrasive material of spunlace non-woven cloth material; another sheet is the abrasive material of industrial scouring pad material; a pair of anti-hair guard circle is sheathed on respectively on the two abrasive material outer ledges, and two abrasive materials and Intermediate substrate are fixed.

Described Intermediate substrate and two abrasive materials are equipped with mesopore;

Described abrasive disc also comprises a pair of anti-hair reinforced sheet, also has mesopore on the anti-hair reinforced sheet, and is fixed from both sides and with abrasive material and Intermediate substrate respectively.

The inner peripheral surface of described anti-hair guard circle evenly is provided with hangnail.

Also evenly be provided with hangnail on the inner surface of described anti-hair reinforced sheet.

Compress bonding mutually by resin adhesive between described abrasive material and the Intermediate substrate.

Compress bonding mutually by resin adhesive between described anti-hair guard circle and the abrasive material.

Compress bonding mutually by resin adhesive between described anti-hair reinforced sheet and the abrasive material.

In technique scheme; bearing tile of the present utility model surface is repaired with abrasive disc and is comprised hard Intermediate substrate, mild abrasives and anti-hair guard circle; two abrasive materials are located at the two sides of Intermediate substrate respectively; a slice is the abrasive material of spunlace non-woven cloth material; another sheet is the abrasive material of industrial scouring pad material; a pair of anti-hair guard circle is sheathed on respectively on the two abrasive material outer ledges, and two abrasive materials and Intermediate substrate are fixed.This abrasive disc can select the abrasive material of two sides unlike material to repair at the different defective in tile fragment surface, and can satisfy the high request of repairing for babbit preferably.

The specific embodiment

Further specify the technical solution of the utility model below in conjunction with drawings and Examples.

See also shown in Fig. 1～3, bearing tile of the present utility model surface is repaired with abrasive disc 10 and is comprised hard Intermediate substrate 11,

mild abrasives

12a, 12b and anti-hair guard circle 13, and Intermediate substrate 11 can adopt artificial stone's sheet to make.Two

abrasive material

12a, 12b are located at the two sides of Intermediate substrate 11 respectively, wherein, a slice is the abrasive material 12a of spunlace non-woven cloth material, it has excellent absorption ability and imbibition ability, and dustless preferably property, softness, antistatic, do not damage performances such as body surface, and have tough durable, efficiently remove water stain, high ability of cleaning greasy dirt and fabulous performances such as antilysis, adopt itself and grease dirt cleaning agent to be used can effectively to be applicable to the cleaning and the reparation of tile fragment surface sheet greasy dirt; Another sheet is the abrasive material 12b of industrial scouring pad material, it has unique open mesh stereochemical structure and elastic grinding characteristic, do not hinder that workpiece, surface treatment effect are level and smooth, to be difficult for obstruction, long service life, Waterproofing/oilproofing, self-sharpening strong, the continuous loss of fiber in process of lapping, new grinding ore in sand form constantly forms naturally, therefore can effectively be applicable to the sintering hard spot on tile fragment surface and the reparation of scratch defects.Consider that use repeatedly can make abrasive material 12a, the 12b edge generation plucking phenomenon of above-mentioned industrial scouring pad and spunlace non-woven cloth; have influence on the reconditioning effect; be sheathed on respectively on two abrasive material 12a, the 12b outer ledge by a pair of anti-hair guard circle 13; and two

abrasive material

12a, 12b and Intermediate substrate 11 be fixed, thereby play the plucking phenomenon that overcomes

abrasive material

12a, 12b edge.And, stressed when the middle part of abrasive disc 10 is installed repeatedly and rotated, also cause the cracked of

abrasive material

12a, 12b and Intermediate substrate 11 easily, this abrasive disc 10 also comprises a pair of anti-hair reinforced sheet 14, anti-hair reinforced sheet 14 is fixed from both sides and with

abrasive material

12a, 12b and Intermediate substrate 11 respectively, is used to overcome the cracked phenomenon at the middle plucking of

abrasive material

12a, 12b and

abrasive material

12a, 12b and Intermediate substrate 11 middle parts.Between above-mentioned

abrasive material

12a, 12b and the Intermediate substrate 11, between anti-hair guard circle 13 and abrasive material 12a, the 12b, all compress bonding mutually between anti-mao reinforced sheet 14 and abrasive material 12a, the 12b by the coating resin adhesive.In addition, for improve and abrasive disc 10 between fastening effect, evenly be provided with hangnail 15 in the inner peripheral surface of anti-hair guard circle 13, also evenly be provided with hangnail 15 on the inner surface of anti-hair reinforced sheet 14.

Please in conjunction with shown in Figure 4, shown in Figure 4 is an Application Example of abrasive disc 10 of the present utility model, this abrasive disc 10 can be designed to circle, and at Intermediate substrate 11, two abrasive material 12a, offer mesopore 16 on 12b and the anti-hair reinforced sheet 14, passing mesopore 16 successively by construction bolt 1 is installed in whole abrasive disc 10 on the mill 3 of sharpening machine 2, need to prove at this, defective according to different tile fragments surface, select the abrasive material 12a or the 12b of respective material to be provided with up, form flour milling, then rotating mechanism 4 drive abrasive discs 10 rotations of sharpening machine 2 are carried out repair to the tile fragment to be repaired surface that is pressed in abrasive disc 10 upper surfaces by hold-down mechanism 5.
