Abstract
Present invention is disclosed a kind of shaft end sheath, the axis (6) is provided with the axle portion (8) being connected with the shaft end (1), bearing (7) is installed on the axle portion (8), described shaft end sheath one end offers the receiving hole (2) for accommodating the shaft end (1), and the outside diameter of the shaft end sheath is less than the internal diameter of the bearing (7).The present invention can be sleeved on the shaft end sheath of shaft end by setting so that will not damage shaft end when installing bearing, oil sealing when ring-shaped work pieces on axis, its is simple in structure, easy to use and reliable.
Description
Technical field
The present invention relates to a kind of shaft end sheath.
Background technology
Ring-shaped work pieces, some shaft ends such as installation bearing, oil sealing are generally required on axis and are provided with screw thread, at this time, are being installed
Or dismounting bearing or oil sealing are easily damaged the screw thread, cause axis to be scrapped when thing；Even if without screw thread, to some surface accuracies
For more demanding axis, wiping easily occurs when mounted and touches, damages shaft end, influences precision；Moreover, it is inserted into oil sealing in shaft end
When, misoperation also can extrusion damage oil sealing sometimes.
The content of the invention
It is an object of the invention to for drawbacks described above of the prior art, there is provided a kind of shaft end sheath, is tearing the axis open
Shaft end will not be damaged when ring-shaped work pieces by filling bearing, the oil sealing being mounted on an axle.
For achieving the above object, present invention employs following technical solution：A kind of shaft end sheath, the axis are provided with
The axle portion being connected with the shaft end, bearing is provided with the axle portion, and described shaft end sheath one end, which offers, accommodates the shaft end
Receiving hole, the outside diameter of the shaft end sheath is less than the internal diameter of the bearing.
In addition, the present invention also proposes following attached technical scheme：
The shaft end sheath other end is equipped with the conical surface.
The depth of the receiving hole is more than the length of the shaft end.
The receiving hole inlet is equipped with chamfering.
The shaft end sheath is made of plastic material.
Compared with the prior art, the advantage of the invention is that：The present invention can be sleeved on the shaft end sheath of shaft end by setting, and make
Shaft end will not be damaged when installing bearing, oil sealing when ring-shaped work pieces on axis by obtaining, its is simple in structure, easy to use and reliable.
Brief description of the drawings
Fig. 1 is the structure diagram of shaft end sheath of the present invention.
Fig. 2 is the use schematic diagram of shaft end sheath of the present invention.
Embodiment
Technical solution of the present invention is further non-limitingly described in detail below in conjunction with preferred embodiment and its attached drawing.
As shown in Figure 1, corresponding to a kind of shaft end sheath of preferred embodiment of the present invention, it is in integrally cylinder, one end
Center offers the receiving hole 2 for accommodating shaft end 1, and the other end is provided with the conical surface 3, and the conical surface 3 and the end face 4 at the end pass through 5 mistake of fillet
Cross.The diameter of receiving hole 2 is slightly larger than the diameter of shaft end 1, and inlet is equipped with chamfering 2a to facilitate the entrance of shaft end 1, receiving hole 2
Depth is preferably slightly larger than the length with shaft end 1.
As shown in Fig. 2, axis 6 includes setting threaded shaft end 1 and installs the axle portion 8 of bearing 7, the diameter of shaft end sheath is less than
The internal diameter of bearing 7, to facilitate the entrance of bearing.When installing or removing bearing 7, the shaft end sheath of the present invention first will be sleeved on axis
On end 1, then bearing is installed again, then the screw thread of shaft end 1 will not be damaged in installation process.
The present invention is equally applicable when installing or removing oil sealing when other ring-shaped work pieces, the conical surface 3 of shaft end sheath ends
Shaft end 1 is loaded in ring-shaped work pieces, so as not to wipe touch, extrusion damage shaft end and ring-shaped work pieces.To prevent shaft end from protecting
Friction damage axis is covered, it uses the material softer than axis to be made, and is preferably the plastics of convenient formation.
The present invention can be sleeved on the shaft end sheath of shaft end by setting so that the ring-shaped work pieces such as bearing, oil sealing are installed on axis
Shi Buhui damages shaft end, its is simple in structure, easy to use and reliable.
It is pointed out that the technical concepts and features of above-mentioned preferred embodiment only to illustrate the invention, its object is to
Allow person skilled in the art to understand present disclosure and implement according to this, the protection of the present invention can not be limited with this
Scope.Any equivalent change or modification in accordance with the spirit of the invention, should be covered by the protection scope of the present invention.
