Assembly tool provided by the embodiment of the utility model by repetition test, and is used for reference and draws horse working principle, in discomfort
Under single-piece or scattered small-scale assembly scene with press machine assembly, tradition percussion assembly hour wheel in the prior art can be overcome
Hub (or shaft coupling) easily there is skew and caused by assembly difficulty and axis be not easy to the problems in, obtain good and effectively fill
It is compared with effect with press machine assembly and saves cost, tapping assembly relative to tradition can guarantee assembling quality again, be readily applicable to list
Part is small-scale, is worthy to be popularized in related small-scale assembly or maintenance production practices.
Below in conjunction with embodiment and its attached drawing, assembly tool provided by the embodiment of the utility model is illustrated.
Fig. 1 is assembly tool structural schematic diagram provided by the embodiment of the utility model.As shown in Figure 1, the utility model is real
The assembly tool for applying example offer includes: including screw 11, screw installation set 12, central axis 13, thrust flange 14 and nut 15.
Specifically, the top of screw 11 is pacified by screw when carrying out the assembly of wheel hub or shaft coupling 22 and motor shaft 21
Encapsulation 12 is mounted on 13 left end of central axis, and the threaded portion of screw 11 is screwed in the internal screw thread of motor shaft 21, and screw 11 is installed
To on motor shaft 21 (or motor output shaft)；Then, wheel hub or shaft coupling 22 are arranged the outer of screw 11 and screw installation set 12
It encloses, wheel hub or shaft coupling 22 is made to keep concentric with motor shaft 21, i.e., wheel hub or axis device 22 are directed at motor shaft 21；Thereafter at center
Successively installed thrust flange 14 and nut 15 on axis 13, tighten nut 15, under the axial thrust of nut 15, by wheel hub or shaft coupling
Device 22 is axial to be pressed on motor shaft 21, to complete the assembly of wheel hub or shaft coupling 22 and motor shaft 21.
When being assembled using the assembly tool, when tightening nut, nut and thrust flange generate biggish friction, thrust force method
Blue face can be worn, and to tighten resistance big for nut, therefore in a preferred embodiment, be installed additional between thrust flange and nut
One thrust bearing, can realize it is good and in the case where effectively assemble, further decrease the abrasion of assembly tool component.Fig. 2
It is the assembly tool structural schematic diagram of a preferred embodiment provided by the embodiment of the utility model.As shown in Fig. 2, this is practical new
