Foreword
This standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces TB/T 1463-2006 "Technical Specification for Wheelsets
Assembly of Railway Locomotive". Compared with TB/T 1463-2006, the main changes
of the technical content of this standard are as follows.

-- The deletion of the provision of residual stress of axle (See 4.2.5 of 2006 edition);
-- The addition of the "classification and selection of wheelsets assembly methods"
(See Chapter 5);
-- The modification of solid wheel interference ratio and oiling pressure range (See
Table 3; Table 2 of 2006 edition);
-- The modification of technical requirements of storage period of components prior
to assembly (See 6.1.5; 5.1.6 of 2006 edition);
-- The addition of molybdenum disulfide lubricant (See 6.2.2 and 6.4.2);
-- The addition of the provision of pressure curve and final press force of 1 press-
fitting method of solid wheel to axle (i.e. press-fitting II) (See Annex C and Annex
D);
-- The addition of the provision of final press force inspection of press-fitting (See
7.1.3 and Table 6);
-- The deletion of quality assurance content (See Chapter 9 of 2006 edition).

Technical Specification for
Wheelsets Assembly of Locomotive
1 Scope
This standard specifies the terms and definitions of the assembly of new wheelsets,
the technical requirements of the assembly parts, the classification and selection of
the assembly methods of wheelsets as well as the technical requirements, inspection
requirements, marking and protection of wheelsets assembly of railway locomotives.
This standard is applicable to the assembly of solid wheel, wheel core, tyred wheel
and other components with axle for newly wheelsets of railway locomotives.
2 Normative References
The following documents are essential to the application of this standard. For the
dated references, only the dated editions apply to this standard. For the undated

3 Terms and Definitions
For the purpose of this Standard, the following terms and definitions apply.
3.1 Oiling press-fitting
An assembly method in which, during the wheelsets press-fitting process, high
pressure oil is injected in between wheel seat and hub bore which exceeds their
contact stress, in order to form an oil film, and in which, along with the increase of the
6.2.1 The interference and oiling pressure shall meet the requirements of 6.1.3.
6.2.2 Prior to press-fitting, the surface of the axle wheel seat and the surface of the
wheel hub inner bore shall be smeared evenly with pure vegetable oil or molybdenum
disulfide.
6.2.3 During press-fitting, the center line of the axle shall be consistent with the center
line of the press piston. The pressing speed shall be 0.5 mm/s ~ 5 mm/s.
6.2.4 The acceptable pressure curves shall be that the pressure increases gradually
with the increase of the pressing distance when oiling, and that the pressure decreases
gradually with the increase of the pressing distance when not oiling. The pressure is
minimum when it is finished pressing, and is less than 196 kN. In the process of oiling
press-fitting, the oiling pressure is allowed to fluctuate within the range specified. See
Annex A for the pressure curve graphs of oiling press-fitting; the pressure curves
without oiling are allowed to have spikes as shown in Fig. C.3 of Annex C.
6.2.5 During the oiling press-fitting of wheelsets, the press machine is allowed to stall
midway. After press-fitting, the residence time is not limited and it is allowed to adjust
the medial distance and phase angle freely.
6.2.6 Each pressure curve graph of wheel oiling press-fitting shall be indicated with.
manufacturer name (or manufacturer code), vehicle type (wheelset type), axle number,
wheel number, hub bore diameter, side, seat diameter, oiling pressure value and press-
fitting date.
6.3 Shrink fitting of solid wheel and core to axle
6.3.1 The magnitude of interference shall meet the requirements of 6.1.3.
6.3.2 The shrink fitting shall be conducted after the heating of solid wheel or core; the
wheel installed with tyre is not suitable for shrink fitting. The heating temperature shall
not exceed 250°C. The surface of the hub bore shall be prevented from oxidation
during heating.
6.3.3 The solid wheel or core shall be wiped clean after they are taken out from the
heating place. After they are assembled to the correct position of the axle, they shall
be cooled indoors under normal temperature until the solid wheel or core are fastened
on the axle seat; they shall not be cooled by forced cooling.
6.4 Press-fitting I of solid wheel, tyred wheel and core to axle
6.4.1 The magnitude of interference shall meet the requirements of 6.1.3.
6.4.2 Prior to press-fitting, the surface of the wheel axle seat and the surface of the
wheel hub inner bore shall be smeared evenly with pure vegetable oil or molybdenum
disulfide.
6.4.3 During press-fitting, the center line of the axle shall be consistent with the center
bore diameter, side, seat diameter, oiling pressure value and press-fitting date.
6.4.9 If the wheel is to be unloaded, it shall be done by oiling according to the oiling
pressure range specified in Table 3.
6.5 Press-fitting II of solid wheel to axle
6.5.1 The interference shall meet the requirements of 6.1.3.
6.5.2 Prior to press-fitting, the surface of the axle wheel seat and the inner surface of
the wheel hub bore shall be evenly smeared with WM-10 or LB-0749 assembly
lubricant.
6.5.3 During press-fitting, the center line of the axle shall be consistent with the center
line of the press piston, and they shall be pressed in parallel. The pressing speed is
preferably 0.5 mm/s ~ 5 mm/s and shall be maintained constant.
6.5.4 The pressure curve graphs shall rise steadily; the pressure during the whole
assembly process nearly increase linearly; and there is slight decrease in speed (a
slight pressure drop is allowed in oiling groove area when there is an oiling groove).
The pressure curve projection length shall not be less than 80% of the theoretical
length. See Annex C for the pressure curve graphs of press-fitting II.
6.5.5 The final pressing force of the press-fitting of solid wheel to axle shall meet the
requirements of Annex D.
6.5.6 Each wheel pressure curve graph shall be indicated with. manufacturer name (or
manufacturer code), vehicle type (wheelset type), axle number, wheel number, hub
bore diameter, side, seat diameter, oiling pressure value and press-fitting date.
6.5.7 If the wheel is to be unloaded, it shall be done by oiling according to the oiling
pressure range specified in Table 3.
6.6 Tyre assembly
6.6.1 Prior to assembling, the surface of the hub inner bore and the rim outer circle
shall be cleaned to prevent damage.
6.6.2 The tyre shall b...
