Abstract
The invention discloses a key-connection combined vertical roll and belongs to the technical field of rolls. The key-connection combined vertical roll comprises a roll shaft and a roll sleeve. The roll sleeve is connected to the outer circumference of the middle of the roll shaft through a key in a matched mode. By adoption of the key-connection combined vertical roll, the problem that the difference between the diameter of a roll body and the diameter of a roll neck of the vertical roll is large, the overall casting gross-to-net ratio is large, and consequentially the production cost is high is solved, the production cost is greatly lowered, the centring performance is good, and the bearing capacity is high.
Description
Technical field
The present invention relates to roll technology field, especially a kind of combination edger roll.
Background technology
The body of roll of hot-strip edger roll is big with roll neck diameter drop, if monoblock cast hair is net than big, blank production cost
Height, can be greatly reduced using bushing mode production cost is combined, but the small edger roll relatively thin for wall thickness of roll shell, it is bushing to combining
Mode proposes requirement higher.Shrinkage connection structure is simple, and centering is good, and bearing capacity is high, and can withstand shocks load, to axle
Strength reduction it is small but higher to fit dimension required precision, it is necessary to machining accuracy higher, roll shaft, roller set are in many cases
Need to be matched, roller set hole size reprocesses roll shaft assembling after processing is cylindrical, increased processing stand-by period, processing
It is less efficient;And roller set need to be heated when assembling, hot charging it is complete after need to be incubated roller set, energy resource consumption is larger,
Assembly period is more long;The interference fit joint magnitude of interference is generally large, cause erection stress larger simultaneously, and spalling risk is high.
The content of the invention
The technical problem to be solved in the invention is to provide one kind and is bonded and connects combination edger roll, reduces production cost, and centering
Property is good, and bearing capacity is high.
In order to solve the above technical problems, the technical solution adopted in the present invention is:
One kind is bonded and connects combination edger roll, including roll shaft and roller set, and the roller set is connected cylindrical in the middle part of roll shaft by key
Zhou Shang.
Technical solution of the present invention further improvement is that:The roll shaft includes the connection in the roll neck portion and stage casing at two ends
Portion, with diameter greater than the roller recess diameter at two ends, connecting portion and the roller set in roll shaft stage casing are interference fit to connecting portion.
Technical solution of the present invention further improvement is that:The magnitude of interference of interference fit is 0.05~0.15mm.
Technical solution of the present invention further improvement is that:The connecting portion one end in the roll shaft stage casing is provided with roller set is fixed
The locating shoulder of position, is threaded with the clamping sleeve for compressing roller set in roll neck portion.
Technical solution of the present invention further improvement is that:Length of the length of the connecting portion less than roller set.
Technical solution of the present invention further improvement is that:One end of the key is provided with guiding wedge angle.
By adopting the above-described technical solution, the technological progress that the present invention is obtained is:
The present invention constitutes edger roll by the form covered by key connection roll in the middle part of roll shaft, and the body of roll for overcoming edger roll is straight with roll neck
Footpath drop is big, the net problem higher than big caused production cost of monoblock cast hair, and production cost is greatly reduced.
Connecting portion and the roller set in roll shaft stage casing are interference fit, and it is 0.05~0.15mm that the magnitude of interference is smaller, is connect by being bonded
Tradition is overcome with the mode of the dual connection of interference fit be only applicable that the interference connected mode magnitude of interference is larger, dimensional fits precision will
Seek problem higher so that centering is good, and bearing capacity is high, bigger shock loading can be born.
The connecting portion one end in roll shaft stage casing is provided with locating shoulder, be threaded with clamping sleeve in roll neck portion, and two ends are determined
Position form ensures that roller set is reliable fixed.The length of connecting portion further ensures that compression is reliable less than the length of roller set.
One end of key is provided with guiding wedge angle, it is ensured that roller is enclosed within correction position that can be gentle in installation process, it is ensured that key
With the correct cooperation that roller covers internal keyway.

Specific embodiment
The present invention is described in further details with reference to embodiment:
Embodiment one:
As shown in Figure 1, 2, 3, one kind is bonded and connects combination edger roll, including roll shaft 1 and roller set 2, the roll neck portion of roll shaft 1 including two ends and
The connecting portion in stage casing, with diameter greater than the roller recess diameter at two ends, the connecting portion and roller in the stage casing of roll shaft 1 cover 2 for interference is matched somebody with somebody to connecting portion
Close, the magnitude of interference of interference fit is smaller, is 0.05~0.15mm.Roller set 2 is connected in the connection in the stage casing of roll shaft 1 by key 3
On the excircle in portion, key 3 is general flat key.Connected key 3 and be connected with by way of the dual connection of interference fit, overcome
Tradition is only applicable that the interference connected mode magnitude of interference is larger, the problem that dimensional fits required precision is higher, also overcomes in tradition only
Using be bonded connect that the body of roll for causing edger roll and roll neck diameter drop be big, net caused production cost is high asks than big for monoblock cast hair
Topic, is greatly reduced production cost, while centering is good, bearing capacity is high, can bear bigger shock loading.
The connecting portion one end in the stage casing of roll shaft 1 is provided with locating shoulder 4, and locating shoulder 4 is realized positioning in roller set 2, do not set
Put and clamping sleeve 5 has been connected through a screw thread in the adjacent roll neck portion of connecting portion of locating shoulder 4, clamping sleeve 5 is realized pressing in roller set 2
Tightly.The length of connecting portion further ensures that compression is reliable less than the length of roller set 2.
