Fig. 3 is the structural representation of spindle unit.
Fig. 4 is the mounting or dismounting schematic representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation.
Like Fig. 1,2, shown in 3, the utility model comprises spindle unit 1, and the front portion of spindle unit 1 is provided with conical surface section 2; Second parts 3 are installed on the spindle unit 1, and second parts 3 are provided with internal taper hole 4, and internal taper hole 4 all is conical with conical surface section 2; Internal taper hole 4 cooperates with conical surface section 2; Conical surface section 2 interference fit of internal taper hole 4 and spindle unit 1, the internal taper hole 4 of second parts 3 are provided with helical oil groove 5, the second parts 3 and are provided with the high pressure oilhole 6 that is communicated with helical oil groove 5.Install for ease and dismantle, spindle unit 1 is provided with the through hole 7 coaxial with spindle unit 1, and the roughness of internal taper hole 4 and conical surface section 2 is not more than 0.8, can avoid when mounting or dismounting, occurring oil leakage phenomenon.The internal taper hole 4 of second parts 3 adds man-hour with the conical surface section 2 of spindle unit 1, match processing, and the contact rate of assurance fitting surface reaches more than 80%.
In the present embodiment, second parts 3 are rack barrel, when installation or removal; Second parts 3 are sleeved on the spindle unit 1; The internal taper hole 4 of second parts 3 contacts with the conical surface section 2 of spindle unit 1, and like Fig. 4, with mandrel 8 hydraulic nut 9 is pressed on second parts 3; High pressure oil pump 10 connects the high pressure oilhole 6 of second parts 3, and low pressure fuel pump 11 connects hydraulic nut 9.Radially pressurize with the conical surface that cooperates of conical surface section 2 through 5 pairs of internal taper holes 4 of the helical oil groove on the internal taper hole 4 by high pressure oil pump 10, the internal taper hole 4 of second parts 3 is expanded outwardly, the conical surface section 2 of spindle unit 1 is inwardly shunk.During installation, progressively heighten the pressure of low pressure fuel pump 11, low pressure fuel pump 11 is exerted pressure through hydraulic nut 9, and second parts 3 are press fit on the spindle unit 1; During dismounting, progressively turn down the pressure of low pressure fuel pump 11, the end thrust that the high pressure oil of high pressure oil pump 10 produces on conical surface section 2 fitting surfaces of the internal taper hole of second parts 34 and spindle unit 1 makes second parts 3 break away from spindle units 1, can easily pull down second parts 3 like this.
