Described guide way is that taper is round table-like.Utilize guide way for taper round table-like will in slip-ring body process of press in, make slip-ring body can there is not skew or topple over; And cost-saving, be convenient to the installation of slip-ring body.
Described gland cross section is " U " type.Contact with slip-ring body annular end face by " U " type gland annular end face; Increase in the process of pushing slip-ring body and the contact area of slip-ring body.
Described piston rod outside is provided with oil cylinder and the separated annular obstruct section of gland.Piston rod outside is provided with annular obstruct section, makes piston rod force localization in the time that extruding promotes gland, and gland is stressed more even, pushing better effects if.
Described gland outside is arranged with sleeve pipe.By coordinating of sleeve pipe and guide, make slip-ring body mobile more stable in pushing course, reduce circular runout.
The invention has the beneficial effects as follows: provide thrust by hollow oil cylinder, make piston rod drive gland to move forward and realize press-fiting of slip-ring body; Make can directly on locomotive, press-fit after slip-ring body maintenance or replacing, reduce the maintenance cost of locomotive, shorten the time between overhauls(TBO) of locomotive, save the cost of overhaul, and greatly shortened locomotive maintenance downtime, have considerable economic benefit and social benefit.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, the present invention is aforesaid will be become apparent with other object, feature and advantage.
Wherein: Fig. 1 is structural representation of the present invention;
In accompanying drawing, 1 is cylinder body, and 2 is double-screw bolt, and 3 is clamp nut, and 4 is piston rod, and 5 is gland, and 6 is annular obstruct section, and 7 is guide way, and 8 is sealing ring, and 9 is slip-ring body, 10 grooves.
The specific embodiment
Shown in Figure 1, slip-ring body press-fits equipment, and it comprises double-screw bolt, and is arranged on the hollow oil cylinder of double-screw bolt end portion; Described hollow oil cylinder comprises cylinder body 1, and is arranged on the piston rod 4 of cylinder body 1 interior hollow, and this piston rod 4 is set in double-screw bolt 2 outsides; The end that described double-screw bolt 2 runs through hollow oil cylinder is connected with clamp nut 3; Described piston rod head end is arranged with the gland 5 that end face contacts with slip-ring body 9; It can be guide pad that described double-screw bolt 2 head ends are fixedly connected with the guide way 7(guide way coordinating with slip-ring body 9, guide table).Provide thrust by hollow oil cylinder, make piston rod 4 drive gland 5 to move forward and realize press-fiting of slip-ring body 9; By guide 7 and main shaft end contact; and slip-ring body is set in guide 7 outsides; guarantee slip-ring body in progradation with the axiality of main shaft end face, guarantee that slip-ring body skids or the skew of position press-fiting to there will not be in process, slip-ring body end face can not worn and not torn press-fiting in process.
Preferably, described hollow oil cylinder head end exit is provided with groove 10, in this groove 10, is placed with sealing ring 8, and described sealing ring 8 adopts discoid sealing ring.Utilize sealing ring 8 to strengthen the sealing effectiveness between piston rod 4 and hollow oil cylinder; Because hollow oil cylinder head end exit is provided with groove 10, sealing ring 8 adopts discoid can better being placed in groove 10, strengthens sealing effectiveness, and sealing ring coordinates the limit effect that can also play hollow oil cylinder with clamp nut 3.
Preferably, described guide way 7 is that taper is round table-like.Between the maximum outside diameter of described taper round platform and slip-ring body 9 internal diameters, adopt matched in clearance, will in slip-ring body 9 process of press in, make slip-ring body can there is not skew or topple over; The round table-like guide way 7 of taper is not only easy for installation, and volume is little, low cost of manufacture.
Preferably, described gland 5 cross sections are " U " type.Contact with slip-ring body 9 annular end faces by " U " type gland annular end face; Increase in the process of pushing slip-ring body and the contact area of slip-ring body, make to push better effects if.
Preferably, described piston rod 4 outsides are provided with hollow oil cylinder and the separated annular obstruct section 6 of gland 5.Piston rod outside is provided with annular obstruct section 6, makes piston rod force localization in the time that extruding promotes gland, and gland is stressed more even, pushing better effects if.
Preferably, described gland outside is arranged with sleeve pipe, between this casing inner diameter and slip-ring body external diameter, adopts matched in clearance.By coordinating of sleeve pipe and guide, make slip-ring body mobile more stable in pushing course, reduce circular runout.
