Abstract

The utility model relates to a renovating board for a large diameter slide shaft bearing, which is a renovating mold board which can be assembled and welded on a large diameter slide shaft bearing which is pre-trimmed and worn. The appearance of the utility model is like a rectangular shaft bush, and the utility model is provided with a groove hole and a rabbet which are convenient for overlay welding connection. When the renovating mold board is used for renovating the large diameter slide shaft bearing, welding flux and time are saved, the forming quality of the renovated shaft bearing is high, the wear-resistant performance is favorable and the continued used period is long.

Description

Major diameter sliding axle bearing is repaired plate

The utility model relates to the acknowledgment copy of major diameter sliding axle bearing reparation usefulness.

Cane sugar manufacture industry now, the manufacture of cement industry, the major diameter sliding axle that paper industry shipping industry and other relevant industry are used is owing to be under the powerful condition of work, and its bearing position wearing and tearing are severe especially, had a strong impact on its service life.For wearing and tearing major diameter sliding axle bearing to a certain degree, traditional restorative procedure is to adopt the mild steel arc welding electrode built-up welding to fill up wear surface, thereby car mill processing resizing reaches the purpose of recovery again. this restorative procedure one is that the consumption scolder is many, the 2nd, time-consuming, the 3rd, the bearing of repairing is because body and weight are difficult to carry out effective heat treatment greatly, just it is low, yielding to get its hardness, and anti-wear performance is poor, continuous not long with the phase.

But the utility model purpose is to disclose a kind of assembly unit to be welded on and to wear and tear and the recovery template on pre-trimmed major diameter sliding axle bearing.

This reparation mould rectangular bearing shell milk Monday.The vertically straight length of template should slightly be shorter than the major diameter sliding axle bearing length that is repaired, the bearing Zhou Jing's that its horizontal arc length (comprising termination seam arc length) should equal to be repaired (n is no less than 2 integer).Template thickness is slightly larger than the design nominal dimension of intact bearing and the difference of the pre-finishing size that runs out bearing, its internal diameter should be identical with the pre-finishing bearing outside diameter of the bearing that has worn and torn, and the template external diameter should be slightly larger than the design bearing size of intact major diameter sliding axle bearing.The recovery template longitudinal centre line has a strip slotted eye, and slotted eye has a horn-like outer opening so that built-up welding has better connection to tighten up performance when connecting.The template both sides respectively have a shape and function all to be same as the hypotenuse of the horn-like outer opening hypotenuse of template longitudinal center line groove hole, all there is an assembly unit seam at two of each template hypotenuse of dawn, the seam width equals half of template longitudinal center line groove hole width, so that the welding slotted eye that it is formed during with adjacent recovery template assembly unit can be consistent with template longitudinal centre line welding slotted eye.

Repair major diameter sliding axle bearing compared with having following advantage with the utility model with traditional restorative procedure:

1, repair material-saving saving of labor.Owing to only need the welding slotted eye at built-up welding template center and edge when repairing major diameter sliding axle bearing, do not need built-up welding bearing whole body, so can save a large amount of scolders and man-hour with this recovery template.

2, the bearing quality height of Xiu Fuing, because this recovery template can be done heat treatment and machined under regular condition, so the bearing Forming Quality height of repairing, anti-wear performance is good, and is continuous long with the phase

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is application feature figure of the present utility model.

As shown in Figure 1 and Figure 2, but the utility model is a kind of assembly unit be welded on worn and torn and the recovery template on pre-trimmed major diameter sliding axle bearing.This recovery template monnolithic case such as same rectangular bearing shell.Vertically straight long (l) of template should slightly be shorter than the bearing length (L) that is repaired, the 1/n (n is no less than 2 integer) of the bearing Zhou Jing that its horizontal arc length (comprising termination, both sides seam arc length) should equal to be repaired.The design nominal dimension that the thickness of template (δ) is slightly larger than intact bearing is poor with the pre-finishing size that runs out bearing, its internal diameter (r) should be identical with the pre-finishing bearing outside diameter of the bearing that has worn and torn, and its external diameter (R) should be slightly larger than the design nominal dimension of intact major diameter sliding axle bearing.Recovery template longitudinally center line has strip welding slotted eye (1), and slotted eye (1) has a horn-like outer opening to tighten up performance so that built-up welding is connected with better connection.Respectively there are all hypotenuses (2) of opening hypotenuse outside template longitudinal center line groove hole is horn-like of a shape and function on the template both sides, and an assembly unit seam (3) arranged all at two of each template hypotenuse, its seam width equals half of template longitudinal center line groove hole width, so that the welding nib that it is formed during with adjacent recovery template assembly unit can be consistent on width with template longitudinal centre line welding slotted eye.The material that this recovery template is selected for use should be consistent with the major diameter sliding axle bearing material that is repaired, its blank can be selected casting, forging method moulding for use, slotted eye, hypotenuse and seam also can adopt machine cut machine-shaping, and the blank after the moulding need pass through strict Quenching Treatment again.After precision turning machine-shaping.When repairing major diameter sliding axle bearing with the utility model, earlier that the bearing wear position is neat by the size turning that is complementary with recovery template, then the recovery template assembly unit is fixed on place, pre-trimmed bearing position, at last with welding rod in the welding slotted eye built-up welding that template longitudinal centre line welding slotted eye and adjacent two template hypotenuses are assemblied to form, more whole bearing is carried out the purpose that turning fine finishining recovery promptly reaches reparation built-up welding is over after.

Claims

1, major diameter sliding axle bearing is repaired plate, for but a kind of assembly unit is welded on through the recovery template on the pre-trimmed major diameter sliding axle bearing that has worn and torn, it is characterized in that its monnolithic case such as same rectangle bearing shell, its vertically straight long bearing length that is repaired that slightly is shorter than, it comprises the 1/n of the bearing Zhou Jing that the horizontal arc length of termination seam equals to be repaired, n is many 2 integer, its internal diameter is identical with the pre-finishing external diameter of the bearing that has worn and torn, its external diameter is slightly larger than the design nominal dimension of intact bearing, thereby its thickness is slightly larger than the design nominal dimension of intact bearing and the difference of the pre-finishing size that runs out bearing, its longitudinal centre line has strip welding slotted eye, the outer opening of slotted eye is horn-like, respectively there is the hypotenuse of a shape similar in appearance to center slotted eye side its both sides, and all there is an assembly unit seam at two of each hypotenuse, and the seam width equals half of central channel hole width.
