Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, but this embodiment should not be construed as restriction of the present utility model.
See Fig. 1 to Fig. 2, the utility model expansion sleeve type bearing puller, comprises the tie down screw 2 of inside and outside coaxial cooperation, rises cone 1 and ringfeder 3 and locking nut 7.See Fig. 3 to Fig. 4, described in the rise top cone angle of the top cone angle beta of cone 1 and ringfeder 3 equal.In expansion process, the linear contact lay of prior art can be become face contact, the frictional force produced like this is larger, makes drawing more reliable.Described cone 1 and the ringfeder 3 of rising is the little structure in large one end, one end.Expansion sleeve type bearing puller also comprises the synchronized links plate 4 matched with multiple ringfeder 3, described synchronized links plate 4 be provided with match with each ringfeder 3 top small end, the installing hole 4.1 relative with bearing inner race.By synchronized links plate 4, multiple ringfeder 3 is linked to be an entirety, to associate ringfeder 3 drawing association bearing, has good effect to the association bearing that not easily separately drawing is removed.The nut of described each tie down screw 2 is held greatly to offset with the bottom of the cone 1 that rises and is connected.
Described synchronized links plate 4 end face is provided with fixed head 5, and described fixed head 5 is provided with corresponding fixing hole 5.1 coaxial with installing hole 4.1 respectively.See Fig. 5 to Fig. 7, the both sides of described fixing hole 5.1 are straightway 5.1.1, and the two ends of described fixing hole 5.1 are arc 5.1.2, and the screw tip sidewall of described tie down screw 2 is two side plane 2.1 two ends cambered surfaces 2.2 and the structure matched with fixing hole 5.1.Fixing hole 5.1 can produce interlock function with this vibrational power flow of tie down screw 2, during by expansion sleeve type bearing puller together with bearing assemble, locking nut 7 is tightened by standard cartridges (not shown), now tie down screw 2 often can rotate along with locking nut 7 together, lifting is caused to rise cone 1, expansion ringfeder 3 needs to consume the more time, fuel pump housing (not shown) due to active bearings (not shown) place is through hole, the nut only needing a hand spanner (not shown) to vise tie down screw 2 is fixed, and another hand standard cartridges (not shown) tightens locking nut 7, but for the fuel pump housing at driven bearing (not shown) place, if blind hole, spanner cannot vise the nut of tie down screw 2 from below, if and housing is too dark or too little, spanner also cannot vise tie down screw 2 and be fixed from above, and adopt this structure of fixing hole 5.1 and tie down screw 2 in the utility model, when tie down screw 2 cannot rotate through being subject to the restriction of fixing hole 5.1 during fixing hole 5.1, not only solve the difficult problem that the locking nut 7 matched with driven bearing is difficult to tighten, and it is simpler to tighten the locking nut 7 matched with active bearings, because do not need the nut vising tie down screw 2 with spanner after interlocking.For ease of tie down screw 2 through width about the 0.5mm larger than the width on tie down screw 2 between two side planes 2.1 between fixing hole 5.1, two straightway 5.1.1.
The screw rod of described each tie down screw 2 is successively through locking nut 7 threaded engagement of the cone 1 that rises, ringfeder 3, installing hole 4.1 and fixing hole 5.1 with top.Be provided with drawing screwed hole 4.2 in the middle of described synchronized links plate 4, described synchronized links plate 4 top is also provided with the pull bar 11 be connected with drawing screwed hole 4.2 screw thread.
The utility model expansion sleeve type bearing puller also comprise to lean with fuel pump housing be connected borrow power plate 8, described fixed head 5 and borrowing to be respectively equipped with drawing screwed hole 4.2 the coaxial fixed head through hole 5.2 that arranges in the middle of power plate 8 and by means of power plate through hole 8.1, described pull bar 11 successively through borrow power plate through hole 8.1 be connected with drawing screwed hole 4.2 screw thread with fixed head through hole 5.2, described borrow power plate 8 end face be also provided with pull bar 11 threaded engagement borrow power nut 10.Be provided with the first pad 6 between described fixed head 5 and locking nut 7, described borrow power plate 8 and borrow between power nut 10 be provided with the second pad 9.Pull bar 11 top is provided with horizontally disposed control stick 12.Described first pad 6 and the second pad 9 are respectively M10 pad and M12 pad, described locking nut 7 and borrow power nut 10 be respectively M10 nut and M12 nut.
The utility model specific operation process is as follows: see Fig. 8 to Fig. 9, first install two ringfeders 3 in synchronized links plate 4, then installation two is risen in cone 1 to two ringfeders 3 respectively, inserts tie down screw 2, through ringfeder 3 and synchronized links plate 4 below the cone 1 that rises.Circumferencial direction rotation lock screw rod 2 is until fixed head 5 is installed on two tie down screws 2.Two tie down screws 2 are installed the first pad 6 and locking nut 7 respectively, twists locking nut 7 with hand but do not tighten.Insert in the inner ring of active bearings and driven bearing by two ringfeders 3, tighten locking nut 7 by standard cartridges, promote the cone 1 that rises, expansion ringfeder 3, then ringfeder 3 produces enough extruding respectively and between active bearings and driven bearing inner race.To be placed on fuel pump housing by means of power plate 8, pull bar 11 is through fuel pump housing and borrow the power plate through hole 8.1 of borrowing on power plate 8 to be connected to threadably on synchronized links plate 4.Rotate and borrow power nut 10, by screw raising rod 11, drive ringfeder 3, active bearings and driven bearing to move upward, extract active bearings and driven bearing.
Described tie down screw 2, the cone 1 that rises, ringfeder 3, locking nut 7 and installing hole 4.1 are 2,3 or 4, described ringfeder 3 is arranged symmetrically with centered by drawing screwed hole 4.2, in a preferred embodiment, see Figure 10, described tie down screw 2, the cone 1 that rises, ringfeder 3, locking nut 7 and installing hole 4.1 are 4, described synchronized links plate 4 is in " ten " word structure, and described drawing screwed hole 4.2 is positioned at the geometric center of synchronized links plate 4.
Obviously, those skilled in the art can carry out various change and modification to the utility model and not depart from spirit and scope of the present utility model.Like this, if these amendments of the present utility model and modification belong within the scope of the utility model claim and equivalent technologies thereof, then the utility model is also intended to comprise these change and modification.
The content be not described in detail in this description belongs to the known prior art of professional and technical personnel in the field.
