Description
Technical field
The present invention relates to the joint shaft bearing structure, relate in particular to a kind of detaching structure of large-scale joint shaft bearing.
Background technique
In the existing joint shaft bearing, bearing mainly comprises outer ring, inner ring, the rotation that cooperatively interacts of inner ring outer spherical surface and outer ring inner ball surface.Axle in the joint shaft bearing is set in the inner ring vertically, and rotates synchronously with inner ring.
The dismounting mode of existing joint shaft bearing mainly comprises two kinds, the first dismounting mode is: as shown in Figure 1, on axle 01, offer in advance hydraulic channel 02, when dismounting bearing 03, injection liquid force feed in the hydraulic channel 02, make axle 01 outer surface circumferential expansion, thereby make bearing 03 inner ring internal surface and axle 01 outer surface effective separation, and then bearing 03 is in axial direction disassembled from axle 01.The second dismounting mode is: as shown in Figure 2, dismounting groove 06 is set in axle 04 and joint shaft bearing 05 inner ring jointing place in advance, when dismounting bearing 05, adopts and draw horse instrument 07 to insert dismounting groove 06, bearing 05 is in axial direction disassembled from axle 04 again.
Respectively there are some shortcomings in the dismounting mode of above two kinds of bearings.Present part joint shaft bearing is specially: because then can't adopt the dismounting mode of the first bearing, so the dismounting mode application area of the first bearing is narrow because structural limitations can't be offered hydraulic channel in axle; Also have in addition the axle in the part joint shaft bearing not to be provided with hydraulic channel, if will adopt the dismounting mode of the first bearing, must be on the axle of buying the rework solution pressure passageway; Simultaneously, the relative bearing of axle easily damages, and needs to change, and the processing cost of processing hydraulic passage is high on axle, behind the axle processing hydraulic passage, in dismounting bearing process, axle is damaged, and causes customer using cost to increase.Adopt the dismounting mode of the second bearing, need in axle and joint shaft bearing inner ring jointing place the dismounting groove to be set in advance, so that draw the horse instrument can conveniently enter removed position, this set weakens the intensity of axle to a certain extent; In addition, after the large size bearing installation time is long, can be combined with the axle rust, therefore, adopt and draw the horse instrument can't dismantle at all, or can't be in the situation that guarantee that not damaging axle disassembles bearing from axle.
Therefore, no matter be to adopt the dismounting mode of the first bearing or the dismounting mode of the second bearing, troublesome poeration not only, and can only dismantle the wherein bearing of a part, can't be generalized to the dismounting of most of joint shaft bearing.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structurely, bearing removal is the detaching structure of large-scale joint shaft bearing easily.
For achieving the above object, the detaching structure of a kind of large-scale joint shaft bearing of the present invention, it comprises outer ring, inner ring and axle, the inner ring center is the cylindrical hole of hollow, and axle is set in the inner ring center hole and with inner ring and rotates synchronously, and inner ring is set in the outer ring, and the inner ring outer spherical surface rotation that matches with the outer ring inner ball surface, described inner ring end face is provided with the high pressure pouring orifice, and the inner ring internal surface is provided with radial ringed oil groove more than, and the high pressure pouring orifice is connected with the radial ringed oil groove of inner ring internal surface.
Adopt above structure, end face at inner ring is provided with the high pressure pouring orifice, the inner ring internal surface is provided with radial ringed oil groove, the high pressure pouring orifice is communicated with the radial ringed oil groove of inner ring internal surface, when the dismounting bearing, from high pressure pouring orifice injection liquid force feed, hydraulic oil flows into annular oil groove from pouring orifice and is communicated with, cause inner ring internal surface circumferential expansion, thereby make inner ring and axle outer surface effective separation, and then bearing in axial direction can be disassembled from axle with less power.
Described high pressure pouring orifice height is convenient to process the high pressure pouring orifice less than half of inner ring height.
When described inner ring internal surface was provided with more than two radial ringed oil groove, each radial ringed oil groove evenly arranged at the inner ring internal surface, is provided with the connection oil guide slot between the radial ringed oil groove.At the inner ring internal surface a plurality of radial ringed oil grooves are set, after hydraulic oil flows into each radial ringed oil groove by the connection oil guide slot, inner ring internal surface many places produce circumferential expansion, with axle to separating effect better, the bearing of inner ring and the outer ring composition of being more convenient in axial direction removes from axle.
Simultaneously, each radial ringed oil groove evenly arranges at the inner ring internal surface, and the circumferential expansion that the inner ring internal surface is produced is even, and inner ring is not yielding like this, is convenient to inner ring yet and removes from axle.
Described connection oil guide slot is more than one, is convenient to like this hydraulic oil and imports rapidly each radial ringed oil groove from the high pressure pouring orifice.
Described connection oil guide slot is sealed at both ends, prevents that hydraulic oil from flowing out from being communicated with the oil guide slot two ends.
Described inner ring internal surface two ends are respectively equipped with seal groove, are embedded with seal ring in the seal groove, even there is a small amount of hydraulic oil to leak out from be communicated with oil guide slot or radial ringed oil groove, seal ring also can seal hydraulic oil, prevent that hydraulic oil from flowing out bearing.
Adopt the detaching structure of large-scale joint shaft bearing of the present invention, at the bearing inner race end face high pressure pouring orifice is set, the inner ring internal surface arranges radial ringed oil groove simultaneously, the circumferential expansion of bearing inner race internal surface generation makes inner ring and axle effective separation like this, and then can easily bearing be removed from axle vertically, this structure has the following advantages:
1, applied range: because the detaching structure of large-scale joint shaft bearing of the present invention need not center roller processing, so this detaching structure can be applicable to all axles, can be user-friendly to.
2, simple in structure, easy to process, only need at inner ring end face processing high pressure pouring orifice, axial oil guide slot and radial ringed oil groove, need not center roller processing hydraulic passage, not only reduce the axle processing cost, reduce user's user cost, and reduce the possibility that axle is damaged, also can guarantee the intensity of axle.
3, disassembling section is convenient, need not use special bearing dismounting tool, only needs then bearing to be removed from axle with less power toward high pressure pouring orifice injection liquid force feed, and in unloading process, axle is not fragile.
