Abstract
A kind of processing method of flange thrust bush is processed lining cylindraceous with the bimetal steel band; Adopt the bimetal steel band to strike out the flange disk; With the inner peripheral surface car of the center hole of this flange disk coning; Outer circumferential face at an end of this lining forms the undergauge flange, and the miner diameter end in the external diameter of this undergauge flange and described flange disc centre hole matches; Outside the undergauge flange of lining one end, and the bigger diameter end of conical center hole that makes the flange disk is towards the top of described undergauge flange with this flange disc centre borehole jack; Undergauge flange top with taper axial compression lining one end of or approximate tapering identical with described flange disc centre hole makes its expansion, compresses locked until the conical inner peripheral surface with flange disc centre hole.Advantage of the present invention is: technology is simple, the manufacturing efficiency height, and adhesion strength is higher than 26 kilograms of pulling force of square millimeter, makes bulldozer, excavator, endless-track vehicle distances travelled such as tank armor are higher than 50,000 kilometers, have prolonged working life.
Description
Technical field
Patent of the present invention relates to a kind of processing method of flange thrust bush, and this flange thrust bush is installed in creeper truck track roller, deflecting roller or draws down on the wheel and play lubrication.Also can be used for the processing of punch press bent axle flip sleeve.
Technical background
Track roller, deflecting roller or the flange thrust bush that draws down wheel are by axle sleeve and be connected the flange disk of one end, and the processing method of this flange thrust bush all adopts centrifugal pressure casting or friction welding that axle sleeve and flange disk are connected together at present.And punch press bent axle flip sleeve adopts the copper lead alloy cast to form, and with being connected by being welded of flange plate, adopting the shortcoming of welding is to cause off-centre easily; Adopt centrifugally cast shortcoming to be, copper-lead tin is because of the proportion difference causes alloy inhomogeneous (partially tin), influences flange thrust bush working life, and a general working year must be changed the flange thrust housing; The shortcoming that adopts friction to connect is because of bonding strength does not reach requirement, the accident that axle sleeve and disk break away from mutually in use often to occur; Adopt the shortcoming of alloy cast to be, because of the nonferrous metal price height, the cost of production height, the scrappage height, manufacturing efficiency is low.
Summary of the invention
The object of the present invention is to provide a kind of processing method of flange thrust bush, adopt copper-lead tin that centrifugal pressure casting exists because of the proportion difference causes alloy inhomogeneous (tin partially), influence flange thrust bush working life to solve prior art; Adopt friction connect existence because of bonding strength does not reach requirement, the accident that axle sleeve and disk break away from mutually in use often appears; And the cost of production height that adopts the alloy cast to exist, scrappage height, the problems that manufacturing efficiency is low.
Technological scheme of the present invention is: this processing method comprises following process step:
(1) is processed into lining cylindraceous with the bimetal steel band; Adopt the bimetal steel band to strike out the flange disk that is provided with center hole.
(2) with the inner peripheral surface car in this flange disc centre hole coning, the angle in this conical inner peripheral surface and axle center is 35 °～55 °.
(3) the outer circumferential face car at an end of this lining goes out stepped shaft, forms the undergauge flange, and the miner diameter end in the external diameter of this undergauge flange and described flange disc centre hole matches.
(4) with this flange disc centre borehole jack outside the undergauge flange of lining one end, and the bigger diameter end of conical center hole that makes the flange disk is towards the top of described undergauge flange.
(5) use the undergauge flange top of taper axial compression lining one end of or approximate tapering identical to make its expansion, compress locked until conical inner peripheral surface with flange disc centre hole with described flange disc centre hole.
Described lining and flange disk all adopt the plumbous bimetal steel band of steel.
Advantage of the present invention is: technology is simple, the manufacturing efficiency height, and adhesion strength is higher than 26 kilograms of pulling force of square millimeter, makes bulldozer, excavator, endless-track vehicle distances travelled such as tank armor are higher than 50,000 kilometers, have prolonged working life greatly.

Embodiment
Referring to Fig. 1～Fig. 5, the processing method of a kind of flange thrust bush of the present invention comprises following process step:
(1) is processed into lining 3 cylindraceous with the bimetal steel band; Adopt the bimetal steel band to strike out the flange disk 1 that is provided with center hole.
(2) coning, this conical inner peripheral surface 2 is 35 °～55 ° with the angle in axle center, and the best is 45 ° with inner peripheral surface 2 cars of this flange disk 1 center hole.As depicted in figs. 1 and 2.
(3) the outer circumferential face car at an end of this lining 3 goes out stepped shaft, forms undergauge flange 4, and the miner diameter end of the external diameter of this undergauge flange 4 and described flange disk 1 center hole matches.As shown in Figure 3 and Figure 4.
(4) with this flange disk 1 center hole is enclosed within outside the undergauge flange 4 of lining 3 one ends, and the bigger diameter end of conical center hole that makes flange disk 1 is towards the top of described undergauge flange 4, referring to Fig. 4.
(5) use undergauge flange 4 tops of taper axial compression lining one end of or approximate tapering identical to make its expansion, compress locked until conical inner peripheral surface 2 with flange disc centre hole with described flange disk 1 center hole.Be processed into finished product according to figure paper size and requirement more at last.
Any one or both sides of outer circumferential face at the undergauge flange 4 of the inner peripheral surface 2 of described flange disk 1 center hole, lining one end are processed with concave-convex grain so that the pressing surface of the two in conjunction with more firm.
Claims (2)
1, a kind of processing method of flange thrust bush is characterized in that: this processing method comprises following process step:
(1) is processed into lining cylindraceous with the bimetal steel band; Adopt the bimetal steel band to strike out the flange disk that is provided with center hole;
(2) with the inner peripheral surface car in this flange disc centre hole coning, the angle in this conical inner peripheral surface and axle center is 35 °～55 °;
(3) the outer circumferential face car at an end of this lining goes out stepped shaft, forms the undergauge flange, and the miner diameter end in the external diameter of this undergauge flange and described flange disc centre hole matches;
(4) with this flange disc centre borehole jack outside the undergauge flange of lining one end, and the bigger diameter end of conical center hole that makes the flange disk is towards the top of described undergauge flange;
(5) use the undergauge flange top of taper axial compression lining one end of or approximate tapering identical to make its expansion, compress locked until conical inner peripheral surface with flange disc centre hole with described flange disc centre hole.
