Description
Technical field
The utility model belongs to technical field of steel rolling, and in particular to a kind of roll shaft end construction of energy fast roll changing.
Background technique
On the output strip line in steel rolling field, there are various roll shafts, such as brush roll, line with rubber roller, support roller, these
Roll shaft will necessarily be worn after long-term production, need to regularly replace and repair, and just needed output strip line to stop production at this time and come
The operation such as roll change maintenance is carried out, and between the roll shaft end of these roll shafts and shaft coupling and between the bearing block and rack of roll shaft
It has connector and attachment bolt needs removes, these connectors of re-attached and attachment bolt after changing new roller need
Certain artificial and roll changing time is spent, production cost and inactivity cost are increased.
Utility model content
The purpose of the utility model is to provide it is a kind of can fast roll changing roll shaft end construction, the structure energy fast roll changing,
It is simple to operate, save production cost.
The technical scheme adopted by the utility model is
A kind of roll shaft end construction of energy fast roll changing, including roll shaft, shaft coupling and bearing block, the end of roll shaft are end axis
Section, secondary end are the secondary shaft part that diameter is greater than end shaft part, and end shaft part and shaft coupling mounting hole cooperate and are keyed, match on secondary shaft part
That closes is cased with axle sleeve, and what is cooperated on axle sleeve is cased with distance collar and bearing, bearing block cooperation cover on bearing and two sides pass through spiral shell
It tethers and is connected to end cap, bearing inner ring is by distance collar and axle sleeve shoulder block axial restraint, and outer race is by two end cap axial restraints, connection
Axis device is bolted with axle sleeve, and distance collar is by shaft coupling and bearing inner ring axial restraint.
Further, shaft coupling is connect by bolt with axle sleeve one end end face, the connecting pin of shaft coupling inner face and axle sleeve
There are gaps for end face.
Further, shaft coupling inner face is equipped with boss, and what axle sleeve was respectively cooperating with covers on boss and time shaft part.
Further, it holds between shaft part and secondary shaft part and passes through conical surface transition.
Further, end shaft part is connect with shaft coupling mounting hole by flat key or spline.
The beneficial effects of the utility model are:
When roll change, do not have to remove any connector and attachment bolt, roll shaft end can directly with shaft coupling and bearing block
It disengages, when reinstalling roll shaft end, need to will only hold the keyway or interior flower of the flat key or external splines and shaft coupling mounting hole of shaft part
Key alignment, is inserted directly into, simple to operate without connecting connector and attachment bolt, has saved production cost.

Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2, in example 1 and example 2, the roll shaft end construction of energy fast roll changing includes roller
Axis 8, shaft coupling 1 and bearing block 6, the end of roll shaft 8 is end shaft part 8-2, secondary end is that diameter is greater than the secondary shaft part for holding shaft part 8-2
8-1, end shaft part 8-2 and shaft coupling mounting hole 1-3 cooperate and are keyed, and what is cooperated on secondary shaft part 8-1 is cased with axle sleeve 7, on axle sleeve 7
Cooperation is cased with distance collar 3 and bearing 5, and what bearing block 6 cooperated cover on bearing 5 and end cap 4, axis has been bolted in two sides
5 inner ring are held by 7 shoulder block axial restraint of distance collar 3 and axle sleeve, 5 outer ring of bearing is by two 4 axial restraints of end cap, shaft coupling 1 and axis
Set 7 is bolted, and distance collar 3 is by 5 inner ring axial restraint of shaft coupling 1 and bearing.When roll change, 8 end of roll shaft can be direct
It is disengaged with shaft coupling 1 and bearing block 6, it, only need to be by the flat key 2 of end shaft part 8-2 or external splines and connection when reinstalling 8 end of roll shaft
The keyway or internal spline of axis device mounting hole 1-3 is aligned, and is inserted directly into, simple to operate, has saved production cost.
As depicted in figs. 1 and 2, in example 1 and example 2, shaft coupling 1 passes through bolt and 7 one end end face of axle sleeve
There are gaps for the connecting pin end face of connection, shaft coupling inner face 1-1 and axle sleeve 7, connect convenient for being adjusted by bolt, to hold out against
Bearing 5 and distance collar 3.
As depicted in figs. 1 and 2, in example 1 and example 2,1 inner face of shaft coupling is equipped with boss 1-2, axle sleeve
7 be respectively cooperating with cover on boss 1-2 and time shaft part 8-1.Guarantee the coaxial of roll shaft 8 and shaft coupling 1, and guarantees that roll shaft 8 is held
The power received is passed in bearing block 6 and rack by axle sleeve 7, bearing 5.
As depicted in figs. 1 and 2, in example 1 and example 2, it holds between shaft part 8-2 and secondary shaft part 8-1 and passes through cone
Face transition, the conical surface are conducive to time shaft part 8-1 and are inserted into axle sleeve 7.
As shown in Figure 1, in example 1, end shaft part 8-2 is connect with shaft coupling mounting hole 1-3 by flat key 2, flat key 2
It is easy to process.As shown in Fig. 2, in example 2, end shaft part 8-2 is connect with shaft coupling mounting hole 1-3 by spline, and spline passes
Dynamic stability, driving torque are big.
It should be understood that for those of ordinary skills, it can be modified or changed according to the above description,
And all these modifications and variations all should belong to the protection scope of the appended claims for the utility model.
