Chang Yanchong, the axle sleeve for needing to renew.Therefore, it is badly in need of a kind of axle sleeve wear-resistant, with high hardness.
Summary of the invention
The technical issues of the utility model solves is existing axle sleeve serious wear after working long hours, and needs to replace again
The axle sleeve renewed can just work on.
In order to solve the above technical problems, technical solutions of the utility model provide a kind of thin plate hot-galvanizing equipment composite shaft
Set, wherein the internal axle sleeve of through-hole is penetratingly equipped with including central location and removably by joinery and its construction and the inner shaft
The outer shaft of installation is covered, the thermal expansion coefficient of the outer shaft is greater than the thermal expansion coefficient of the internal axle sleeve.
Optionally, the lateral wall of the internal axle sleeve penetratingly offers multiple mounting grooves in the axial direction.
Optionally, the mounting groove is the mounting groove of oat tail groove structure.
Optionally, multiple connection convex blocks are provided on the inner sidewall of the outer shaft with protruding outward.
Optionally, the outer profile structure of the connection convex block is in oat tail groove structure.
Optionally, the oat tail groove structure of the mounting groove is identical as the connection oat tail groove structure shape of convex block, and institute
The oat tail groove structure size for stating mounting groove is greater than or equal to the oat tail groove structure size of the connection convex block.
Optionally, the connection convex block is matched with the size of the mounting groove, and between the internal axle sleeve, the outer shaft
It is mounted or separated by the mortise-tenon joint realization of the mounting groove, the connection convex block.
Optionally, the material of the outer shaft is titanium carbide.
The beneficial effect of technical solutions of the utility model is:
The utility model is by being arranged axle sleeve in dismountable two individual internal axle sleeves and external shaft sleeve structure, and outer shaft
The thermal expansion coefficient of set be greater than internal axle sleeve thermal expansion coefficient, during the work time, outer shaft due to thermal expansion and contraction principle with it is interior
Axle sleeve securely connects, and the hardness of outer shaft is high, significantly improves the service life of axle sleeve, further improves equipment
Service life and working efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of thin plate hot-galvanizing equipment composite shaft sleeve in the utility model embodiment；
Fig. 2 is the structural schematic diagram of internal axle sleeve in the utility model embodiment；
Fig. 3 is the structural schematic diagram of outer shaft in the utility model embodiment.
Specific embodiment:
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, but not as the utility model
It limits.
Referring to Figure 1, shown in Fig. 2 and Fig. 3, a kind of thin plate hot-galvanizing equipment composite shaft sleeve 1 of embodiment is shown,
In, composite shaft sleeve 1 include central location be penetratingly equipped with through-hole 4 internal axle sleeve 2 and removably by joinery and its construction with it is interior
The outer shaft 3 that axle sleeve 2 is installed, the thermal expansion coefficient of outer shaft 3 are greater than the thermal expansion coefficient of internal axle sleeve 2.
In the present embodiment, the lateral wall of internal axle sleeve 2 penetratingly offers multiple mounting grooves 21, mounting groove in the axial direction
21 be the mounting groove of oat tail groove structure.It is provided with multiple connection convex blocks 31 with protruding outward on the inner sidewall of outer shaft 3, connects convex
The outer profile structure of block 31 is in oat tail groove structure.
In the present embodiment, the oat tail groove structure of mounting groove 21 is identical as the connection oat tail groove structure shape of convex block 31, and pacifies
The oat tail groove structure size of tankage 21 is greater than or equal to the oat tail groove structure size of connection convex block 31.Connect convex block 31 and mounting groove
21 size matching, and between internal axle sleeve 2, outer shaft 3 by mounting groove 21, connect convex block 31 mortise-tenon joint realize installation or
Separation.
In the present embodiment, the material of outer shaft 31 is titanium carbide.
Pass through the following characteristic and function for illustrating further insight the utility model.
Present embodiment discloses a kind of composite shaft sleeves strong applied to the hardness height of flat cold-rolled sheet hot-galvanizing equipment, wearability
1, composite shaft sleeve 1 includes the internal axle sleeve 2 and outer shaft 3 detachably installed, and passes through dovetail groove type between internal axle sleeve 2 and outer shaft 3
Mortise-tenon joint Standard.By being in dismountable two individual internal axle sleeves 2 and 3 knot of outer shaft by the setting of composite shaft sleeve 1
Structure, and the thermal expansion coefficient of outer shaft 3 is greater than the thermal expansion coefficient of internal axle sleeve 2, during the work time, outer shaft 3 is due to heat expansion
Shrinkage principle is securely connect with internal axle sleeve 2, and the hardness of outer shaft 3 is high, significantly improves the service life of axle sleeve, further
The service life and working efficiency for improving equipment.
The above is only the utility model preferred embodiments, are not intended to limit the embodiments of the present invention and protection
Range should can appreciate that all with the utility model specification and diagramatic content institute to those skilled in the art
