Abstract
The utility model discloses an internal jaw for a bearing, which is a special tool for the bearing for dismounting the turning part of a machine. The utility model is composed of a turning handle, a screw thread drive rod, a calibration ring, a jaw body, etc. The jaw body clamps the inner diameter of the bearing, and the turning handle is operated so that the bearing can be conveniently dismounted.
Description
The utility model belongs to the repair of machine instrument.
At present, during the damage of bearings of mechanical rotation part, people beat outward with hammer or other hard thing usually, and are not only time-consuming but also require great effort, and repair very inconvenient.
The purpose of this utility model be design a kind of with metal make by turning handle, the screw thread drive link, the setting circle, the bearing bore diameter pawl that corpus unguis etc. are partly formed, it can take out bearing easily from support.
The utility model adopts screw rod to promote the internal diameter pawl technical scheme that bearing ejects is achieved the above object.
Now in conjunction with the accompanying drawings and embodiments the utility model is described in detail as follows:
Fig. 1 is the schematic diagram of bearing bore diameter pawl.
1 is turning handle among the figure, and 2 is the screw thread drive link, and its upper end is a level and smooth ladder, this ladder can be made into hexahedron or tetragonal body, so that the use spanner, present embodiment is to be drilled with a hole and turning handle coupling at this ladder middle part, and taper is made in the lower end of screw thread drive link.The screw thread drive link is engaged with the corpus unguis 4 that has internal thread.Two parts symmetrical in the middle of corpus unguis is divided into, every part is a semi arch body, and the pawl 6 of extension is arranged respectively in the lower end of two semi arch bodies, after the butt joint of two halves circular arc body, middle for having the hole of internal thread, internal thread and screw thread drive link are complementary.Positioning step 5 with centring ring 3 coupling is arranged on the corpus unguis, and the lower end of corpus unguis with keyways in the middle of two perpendicular having of semi arch extension pawl, is convenient to two semi arch physical efficiencys and is inserted respectively and wait to unload in the bearing bore diameter.
The bearing bore diameter pawl of the utility model design in use, earlier with two semi arch bodies respectively by waiting to unload the internal diameter of bearing, make the extension pawl block bearing bore diameter, with the setting circle corpus unguis is fixed, the screw thread drive link screws in corpus unguis, and tapered end props up corresponding hard thing, operation turning handle, utilize screw thread to transmit top power, bearing is unloaded from support.
Claims (1)
1, a kind of bearing bore diameter pawl, it is characterized in that the screw thread drive link carries out interlock with the corpus unguis that has internal thread, two parts symmetrical in the middle of corpus unguis is divided into, every part is a semi arch body, having respectively in the lower end of two semi arch bodies on the pawl, corpus unguis of extension has and the positioning step of setting circle coupling, the lower end of corpus unguis, with keyway in the middle of two perpendicular having of semi arch extension pawl.
