Abstract

The invention belongs to bearing shell manufacture field, a kind of production technology of tin aluminium silicon bearing shell fatigue resistance in lifting is referred specifically to, the present invention includes：Alloy-layer, right boring, pickling, finishing, baking step are prepared in bearing shell steel back, the present invention integrates right boring and finishing process first, effectively improves bearing shell surface property, lifts bearing shell fatigue resistance.

Description

The production technology of tin aluminium silicon bearing shell fatigue resistance in a kind of lifting
Technical field
The invention belongs to bearing shell manufacture field, especially in a kind of lifting tin aluminium silicon bearing shell fatigue resistance production technology.
Background technology
Middle tin aluminium silicon bearing shell in the market is generally three-decker, be respectively as matrix steel back layer, be attached to The sputtered layer of alloy-layer and sputter over the alloyed layer on steel back layer.The major significance of sputtered layer is to make by sputtering process Bearing shell surface obtains smooth degree, and the flexible material of sputtered layer makes bearing shell surface possess compliance, so as to lift bearing shell Fatigue resistance in friction.But bearing shell sputter requires very high to sputtering equipment, involves great expense.Now with some processes Bearing shell is set not need sputtered layer to meet to use needs by the material and technique that improve alloy-layer, but this improvement exists Substantially there is the fatigue resistance for not possessing the bearing shell for carrying out sputter processing in experiment, it is therefore necessary to which depth is carried out to this bearing shell With the processing of precision, properties of product are further lifted.
The content of the invention
The present invention discloses a kind of production technology of tin aluminium silicon bearing shell fatigue resistance in lifting, passes through centering tin aluminium silicon bearing shell Further finishing, makes such bearing shell both not need further sputter, and and can has more excellent compared to tin aluminium silicon bearing shell in tradition Fatigue resistance, the technical scheme is that：
A, alloy-layer is prepared in bearing shell steel back, the alloy-layer includes, tin 7-9%,
Copper 3% 、Graphite 1.5%, zinc, 0.3%, silicon 0.8%、Aluminium is surplus
B, right boring is carried out to the inner surface of bearing bush for preparing alloy-layer, the radius of corner of boring cutter is R6, boring cutter feed velocity and boring Knife speed of mainshaft ratio is 0.25
C, pickling is carried out to the bearing shell after right boring, Acidwash solution is the hydrochloric acid that concentration is 8%, pickling time 8-10 minutes, pickling temperature Spend 30-35 degree
D, the bearing shell after pickling is inserted into finishing in polishing machine, finishing sand uses ceramic material, 2 millimeters of finishing sand grain diameter, 5-10 minutes finishing time.
E, dry, drying temperature 180 degree, drying time 0.5-1 minutes
The effect of of the invention is that company carries out right boring to the middle tin aluminium silicon bearing shell processed, and boring cutter radius of corner is arranged to R6, boring Knife feed velocity is 0.25 with the control of the boring cutter speed of mainshaft, so processes ring grain in inner surface of bearing bush, and can control ring grain The difference of crest and trough between 0.001-0.003 ㎜, the width of ripple between 0.20-0.40 ㎜, this technology equivalent to The loaded area of inner surface of bearing bush is increased, reduces the flowing velocity of lubricating oil, the minimum oil film for increasing bearing shell and bent axle is thick Degree, so as to add the bearing capacity of oil film, strengthen bearing shell radiating effect, extend the service life of bearing shell, therefore with same material Expect the bearing shell of manufacture, fatigue resistance can increased.Finishing processing is carried out to the bearing shell after right boring, eliminated except playing The small burr of product surface, acute angle is become round and smooth, improve the effect of the cleannes of product, finishing can also make bearing shell surface Pit row processing texture is presented under micro- Electronic Speculum, this is more beneficial for oil storage than ring grain caused by previous step right boring；And make Ra numbers Value reduces, and so as to improve the wearability of bearing shell and fatigue resistance, the finishing bearing shell technology of company's invention produces top grade Shaft for engine watt be supplied to each user, and introduce to the market, improve the presentation quality of bearing shell, enhance the usability of bearing shell Energy.Finishing bearing shell has the following advantages compared with original bearing shell：1. effectively removing the burr of bearing shell processing, rounding sharp edge is special It is not mechanical and artificial unapproachable R<0.1 garden angle, is reached with technique can.2. refine finished surface tissue State, make up due to deficiency caused by machining, machining is obtained the unapproachable roughness of bearing shell working surface Extension, bearing shell working surface roughness reaches Ra0.3, while steel back face is brought into close contact with bearing block, enhances thermal conductivity, is subtracted The small microseism of bearing shell and bearing block.The initial wear of conjunction phase 3. completion rubs, improves overall performance, improves the reliability of bearing shell And anti-fatigue life, because pit row processing texture is presented in burnishes under micro- Electronic Speculum, this is more beneficial for storing up than ring grain, reticulate pattern Oil；Reduced plus Ra numerical value, so as to improve the wearability of bearing shell and fatigue resistance, through Ministry of Railways's product quality supervision and inspection The sapphire fatigue experiment that the bearing shell that center produces to great Feng bearing shells company is done proves that the fatigue strength of finishing bearing shell improves More than 20%.4. the cleannes after the assembly performance of improvement engine complete machine and assembling, after tested：The bearing shell installation of non-finishing needs Will longer running-in time, finishing bearing shell and related finishing part installation after, the running-in time is greatly shortened more than 50%.Tool Body embodiment
The present invention discloses a kind of production technology of tin aluminium silicon bearing shell fatigue resistance in lifting, comprises the following steps,
A, alloy-layer is prepared in bearing shell steel back, the alloy-layer includes, tin 7-9%,
Copper 3% 、Graphite 1.5%, zinc, 0.3%, silicon 0.8%、Aluminium is surplus
B, right boring is carried out to the inner surface of bearing bush for preparing alloy-layer, the radius of corner of boring cutter is R6, boring cutter feed velocity and boring Knife speed of mainshaft ratio is 0.25
C, pickling is carried out to the bearing shell after right boring, Acidwash solution is the hydrochloric acid that concentration is 8%, pickling time 10 minutes, pickling temperature 35 degree
D, the bearing shell after pickling is inserted into finishing in polishing machine, finishing sand uses ceramic material, 2 millimeters of finishing sand grain diameter, 10 minutes finishing time.
E, dry, drying temperature 180 degree, drying time 0.5 minute.
