Embodiment
embodiment 1
If Fig. 1 is a kind of novel motor pulley extractor structural representation, comprise that as shown in Figure 5 anti-take turns the baffle plate that flies out, polydonita type three-jaw, pulling force chain, positioning metal ring as shown in Figure 4.Anti-ly take turns fly out baffle plate and described pulley extractor split setting, positioning metal ring and described pulley extractor split arrange.Polydonita type three-jaw is connected with nut locator by pulling force chain respectively.Pulling force chain is clamped respectively three pawls of polydonita type three-jaw and is used screw and nut to fix, and the top of described polydonita type three-jaw is provided with draw-in groove, and the side opening of draw-in groove is provided with otch.
Present embodiment medium power device is leading screw, and the centre bore of nut locator passes through for leading screw, and three pawls of the edge corresponding polydonita type three-jaw of nut locator are provided with nut fixing device, and the edge of nut locator also arranges Metallic rod.
Described anti-take turns the baffle plate that flies out in the form of annular discs and its on arrange porose.Described positioning metal ring is evenly equipped with 6 holes, 6 jackscrews are set in hole to be passed, lower end is spherical in shape or the jackscrew of taper is crisscross arranged, when positioning metal ring is fixedly connected with polydonita type three-jaw, lower end penetrating in draw-in groove of jackscrew spherical in shape is fixedly connected with, and the tapered jackscrew in lower end withstands on pulley groove.
While using the pulley extractor that this embodiment provides, first the belt pulley plate washer screw of motor is laid down, taken off belt pulley baffle plate, load onto the anti-plate washer that flies out of taking turns, screw does not tighten, in case preserved skin belt wheel top pine moment flies out; Then polydonita type three-jaw is placed on pulley groove, living polydonita type three-jaw by positioning metal ring set fixes with jackscrew again, other three on positioning metal ring in uniform six jackscrews withstand on pulley groove, to play righting swelling, pulling force chain is fixedly linked polydonita type three-jaw and nut locator by screw, fix by nut, leading screw withstands on Pulley shaft through the anti-hole flying out on plate washer of taking turns, then use in the Metallic rod of one section of steel pipe socket on nut locator, standby pincers stopping function is played in one end of Metallic rod on ground or other table top.In the time of rotating threaded shaft, prevent that nut locator from rotating, the rotating threaded shaft of now exerting oneself, makes belt pulley produce the axial thrust that departs from electric motor axle, thereby extracts belt pulley.
