Abstract
The utility model provides a babbitt metal bearing pad with a bonding layer. The babbitt metal bearing pad comprises a copper pad back (1) and a babbitt metal layer (3), wherein an iron layer (2) is plated on the surface (back onto the babbitt metal layer (3)) of the copper pad back (1), and the babbitt metal layer (3) is poured on the iron layer (2) which is 0.0127-0.0762mm thick. According to the babbitt metal bearing pad, the iron layer is plated on the surface of the copper pad back, which is back onto the babbitt metal layer; the bonding strength of the iron layer and the copper pad back is good, the iron layer can be used for effectively avoiding forming Cu6Sn5 or Cu5Sn4, and an iron plating process has the advantage of low toxicity.
Description
Technical field
The utility model relates to a kind of babbit metal bearing tile fragment with binder course.
Background technique
The sliding bearing of applying in industry has a variety of, but most of sliding bearing all has similarly the typical structure being comprised of watt back of the body and soft metal or Babbitt.These bearings will be faced harsher running environment when operation; inefficacy under extreme case may cause catastrophic effect; light pay maintenance expenses and the shutdown loss of tens thousand of units; heavy cause the damage of other static part; during especially severe, even can cause rotating shaft to damage, may need the maintenance expenses of millions of units.
Have a key factor that affects bearing operation can not be ignored, that is exactly the bond quality of Babbitt and watt back of the body.Babbitt has extremely vital impact with the bond quality of watt back of the body for the reliability of bearing.
Most manufacturers can require binder course when using non-destructive inspection (UT), has more than 90%, even 100% combination rate.So in copper and chromiumcopper can incline watt, transfer in copper or chromiumcopper and form Cu if tin by tining and pour into a mould Babbitt, can occur copper or the chromiumcopper watt back of the body so

To the copper back of the body, nickel plating is a kind of means that solve the problems of the technologies described above, but because tin also has similar phenomenon of osmosis with nickel, the problem that copper tin interpenetrates still exists on a small quantity.Nickel plating is not only expensive in addition, and environment is had to larger negative effect.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provide that a kind of cost is low, environmental pollution is little and can solve watt back of the body in brasses back of the body Babbitt tile fragment and Babbitt in conjunction with forming Cu

The technical solution adopted in the utility model is: comprise the brasses back of the body and babbit layer, the described brasses back of the body is coated with an iron layer on the surface of babbit layer, and babbit layer casts on iron layer.
In the above-mentioned babbit metal bearing tile fragment with binder course, the thickness of described iron layer is 0.0127-0.0762mm.
Compared with prior art, the beneficial effects of the utility model are: the babbit metal bearing tile fragment with binder course of the present utility model is coated with an iron layer at the brasses back of the body on the surface of babbit layer, iron layer and the brasses back of the body have good adhesive strength, and iron layer can effectively prevent Cu

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, the babbit metal bearing tile fragment with binder course of the present utility model comprises the brasses back of the body 1 and babbit layer 3, and the described brasses back of the body 1 is coated with an iron layer 2 on the surface of babbit layer 3, and babbit layer 3 casts on iron layer 2; The thickness of described iron layer 2 is 0.0127-0.0762mm.
An electroplating technology for iron layer 2, comprises the steps;
1) prepare the completely ferrous chloride solution of 2/3 capacity of 240 liters of clean barreleds, add calcium carbonate to stir, and at room temperature make pH value reach 0.5～4.0, standing and precipitated impurities, then transfers to the mixed solution after precipitation in electroplating pool; Repeat above operation, and the electroplating pool of annotating is to needed amount.
2) solution in electroplating pool is heated to 38～52 ℃, the solution in electroplating pool is filtered with circulated filter system, until solution becomes limpid emerald; The filter screen specification of circulated filter system is from 100 microns to 3 microns.
3) solution temperature in electroplating pool is adjusted to 72～78 ℃, pH value is adjusted to 1.0～1.2, and the concentration of iron is 28%～30%;
4) 12 pure iron electrode rods are positioned in electroplating pool, the many ferroelectric utmost points are connected on same electrode, and this electrode is connected on a cathode power supply and rectifier; A negative electrode shelf is disposed in electroplating pool to cathode carrier sub-connection power cathode.
5) a false negative electrode is stretched out and inserts electroplate liquid from negative electrode shelf; Described false negative electrode is the Corrugated Steel after dezincify.
6) open and electroplate control power supply, false negative electrode is electroplated, to the uniform grey of false negative electrode covering one deck; During plating, electroplating voltage is 1V, and current density is 3000A/ ㎡, and electroplating time is 4h.
7) surface of the electroplated of the cleaning brasses back of the body 1, and by the surface of electroplated just to pure iron electrode.
8) the brasses back of the body 1 is electroplated, electroplated the afterflush brasses back of the body; During plating, current density is 3000A/ ㎡, and electroplating time is 30-45min.
Claims (2)
1. there is a babbit metal bearing tile fragment for binder course, comprise the brasses back of the body and babbit layer, it is characterized in that: the described brasses back of the body is coated with an iron layer on the surface of babbit layer, and babbit layer casts on iron layer.
