Abstract
The present invention discloses double rolling way roller bearing assembling process and special correcting tool for loom. The assembling process includes matching steel balls, spindle and bearing casing with double rolling way. The tools including back row tool, front row tool, shifting pin, radial interval correcting pin and U-shaped spring clamp are used in the assembling of spindle, bearing casing, back holder, back row of balls, front row of balls, front holder, etc. Using double rolling way bearing to replace single rolling way bearing has the effects of prolonged service life, homogeneous pressure, smooth rotation and raised yarn quality.
Description
Technical field
The present invention relates to two raceway upper roller bearing assembly technologies of frame and special correcting circuit instrument thereof.
Background technology
The frame upper roller bearing plays drawing-off, the draw of yarn when the spinning running, the stability of bearing operation is directly connected to yarn drawing-off, traction quality, influence the thickness evenness of yarn evenness, quality influence to high grade yarn is particularly evident, therefore the workmanship to upper roller bearing has strict demand, according to the industry ministry standard, its radial clearance requires to be controlled between 0.003～0.03 millimeter.Traditional upper roller bearing is single raceway structure, promptly back row steel ball is installed between the R circular groove and cartridge housing endoporus of mandrel, front-seat steel ball is installed in single raceway of mandrel R circular groove and cartridge housing R circular groove, form back row's steel ball and cartridge housing endoporus line contact relation, back each steel ball of row is moved on different separately tracks, cause the cartridge housing endoporus to be exceedingly fast and wear and tear and the formation gap, bearing is very short service life, often transposing needs the great deal of steel input, and yarn qualities is caused havoc." upper roller bearing " of Chinese patent 92213968.7 (this patent was terminated in 96 years) proposed two raceway structures, be bearing before, back row's steel ball all is installed in two raceways of each free mandrel R circular groove and cartridge housing R circular groove composition, the wearing and tearing that are exceedingly fast of having avoided back row's steel ball and cartridge housing endoporus to be brought because of line contacts form the gap, bearing life is prolonged greatly, yarn qualities also improves greatly, but the steel ball of a two raceway structures assembling difficult problem can not get solving always, there is not suitable specific purpose tool yet, especially the assembling difficulty of back row steel ball be everybody knows, cause on the market and still using traditional single race bearing, making double row bearing strangle can't be applied in cradle, is a matter of regret in fact.
Summary of the invention
Technical problem to be solved by this invention provides a kind of two raceway upper roller bearing assembly technologies of frame and special correcting circuit instrument thereof that solves a double row bearing assembling difficult problem with regard to being to make double row bearing be able to wide popularization and application.
Technical problem of the present invention is achieved through the following technical solutions.
The two raceway upper roller bearing assembly technologies of a kind of frame is characterized in that:

17.5 ± 0.015 millimeters of=Φ; Cartridge housing 2 endoporus aperture D=Φ 14.7+0.08 millimeters, back raceway 11 diameter D
115.5 ± 0.015 millimeters of=Φ, preceding raceway 12 is identical with back raceway 11 dimensional requirements;
B, after mandrel 5 medium position covers install the second mate retainer 8, second mate " worker " font dust ring 4 and second mate " O " type oil-resistant seal ring 7;
C, at bearing one end back row's steel ball is installed: row's steel ball 3 is inserted in row's specific purpose tool (prior art) axis hole of back after with 5, this moment, steel ball was arranged in monolateral position arbitrarily because of the special tectonic of back row's specific purpose tool, earlier cartridge housing 2 is placed on above-mentioned specific purpose tool top, use the hand pressing, make back row's steel ball 3 enter raceway 11 behind the cartridge housing, again mandrel 5 is inserted in the cartridge housing steel ball, back row's steel ball is entered in the back raceway of being made up of mandrel and cartridge housing;
D, the radial clearance of proofreading and correct back row's steel ball: above-mentioned mandrel 5, cartridge housing 2, back row's steel ball 3 etc. are installed on radial clearance together proofread and correct on the post (Fig. 7～8), with dialling pin (prior art, as follows) stir and afterwards arrange steel ball, require back row's steel ball 3 in the raceway 11 of back, to rotate flexibly with feel, but must not become flexible, reach gap appropriateness requirement by the steel ball size of changing different steppings;
E, continuation are proofreaied and correct on the post in above-mentioned radial clearance, it is monolateral to push back row's steel ball 3 to back raceway 11 with " U " type Spring Card, and prop up back row's steel ball with " U " type Spring Card and fix, after making when front-seat steel ball 10 is installed, back row's steel ball can not break away from the back raceway, takes out mandrel 5 (Fig. 9～10) then;
F, the cartridge housing 2 that will have back row's steel ball 3 and " U " type Spring Card are proofreaied and correct post from radial clearance together and are taken off;
G, front-seat steel ball is installed: front-seat steel ball 10 is inserted in front-seat specific purpose tool (prior art) axis hole, the same with above-mentioned back row's steel ball 3, be arranged in arbitrarily on the monolateral position, cartridge housing 2 is placed on the above-mentioned specific purpose tool, the pressing cartridge housing, after making front-seat steel ball 10 enter the preceding raceway 12 of cartridge housing, take off from above-mentioned specific purpose tool;
H, mandrel 5 is inserted in above-mentioned forward and backward row's steel ball again, forward and backward row's steel ball promptly enters respectively in the forward and backward raceway of being made up of mandrel and cartridge housing, and stir front-seat steel ball with dialling pin, treating to be evenly distributed substantially is pressed into front-seat retainer again, front-seat steel ball 10 is evenly distributed on before in the retainer 9;
I, take off " U " type card, stir back row's steel ball 3 and be uniform substantially, be pressed into the back retainer then, back row's steel ball 3 is evenly distributed in the retainer 8 of back with dialling pin;
J, a pair " worker " font dust ring 4 and pair " O " type oil-resistant seal ring 7 are pushed above-mentioned cartridge housing 2 rear ends along mandrel 5;
K, repeat above-mentioned operation c～j, the bearing other end is carried out the part assembling.
The present invention is in assembling process, and except above-mentioned described back row's specific purpose tool, front-seat specific purpose tool, to dial pin be the prior art, radial clearance proofreaies and correct post and " " the type Spring Card is that back row's steel ball 3 assemblings for two raceway upper roller bearings design to U.
Radial clearance is proofreaied and correct post (Fig. 4) and is the multidiameter shape, form by base 15, cartridge housing location shoulder 14, axle sleeve 13, cartridge housing location shoulder 14 and the processing of axle sleeve 13 disjunctors, press fit in cup dolly 15 axis holes, interporal lacuna is equipped in axle sleeve 13 external diameters and the cartridge housing 2, and axle sleeve 13 endoporus and mandrel 5 crest clearances are equipped.The correction post requires the inside and outside circle of axle sleeve coaxial, and vertical with cartridge housing location shoulder, is press-fitted the back processing simultaneously on the equipment on the same stage, guarantees required precision, and proofreading and correct for the radial clearance of back row's steel ball provides the frock assurance.
" U " type Spring Card (Fig. 5～6) is made by spring steel, comprise " U " font card body 16, the termination of card body is bent into nearly 90 ° of shifting blocks 17, hold the card body with hand-power during use, after waiting to enter the cartridge housing endoporus, hand loosens, and two shifting blocks can promote back row's steel ball 3 and roll along back raceway 11 because of elastic force opens.
