The problem of existing for prior art, the utility model embodiment provide a kind of straightener interference fit device,
For solving in the prior art in the smooth production line production of steel rolling, aligning roller shaft head and spindle axle sleeve easily disengage, and cause to give birth to
Produce the technical problem that efficiency declines.
The utility model provides a kind of interference fit device, and described device includes：Align roller shaft head and spindle axle sleeve；Its
In,
The endoporus of the aligning roller shaft head and the spindle axle sleeve is cylinder, and the aligning roller shaft head and described is connect
It is interference fit between axle axle sleeve.
In such scheme, described device also includes：Spindle, the spindle axle sleeve are connected with the spindle by connector.
In such scheme, the interference fit length between the aligning roller shaft head and the spindle axle sleeve is 150mm.
In such scheme, the magnitude of interference of the interference fit between the aligning roller shaft head and the spindle axle sleeve is
0.146mm。
In such scheme, the diameter of the aligning roller shaft head and the internal diameter of the spindle axle sleeve are 89mm.
In such scheme, the connector includes：Connecting bolt.
In such scheme, the coefficient of friction between the aligning roller shaft head and the spindle axle sleeve is 0.1.
In such scheme, the material of the aligning roller shaft head is 9Cr2Mo.
In such scheme, the yield strength of the aligning roller shaft head is 900MPa.
In such scheme, the safety coefficient of the aligning roller shaft head is 3.5~4.0.
The utility model provides a kind of straightener interference fit device, and described device includes：Align roller shaft head and spindle
Axle sleeve；Wherein, the endoporus of the aligning roller shaft head and the spindle axle sleeve is cylinder, and the aligning roller shaft head and described
It is interference fit between spindle axle sleeve；In this way, because being interference fit between aligning roller shaft head and the spindle axle sleeve, pass through spindle nose
Frictional force between axle sleeve avoids and vibrations is produced between aligning roller shaft head and the spindle axle sleeve to transmit moment of torsion, and then
Avoid aligning roller shaft head and spindle axle sleeve disengages, improve production efficiency.
Brief description of the drawings
Fig. 1 is the overall structure diagram that the straightener that the utility model embodiment provides is interference fitted device.
Description of reference numerals：
1- aligns roller shaft head；2- spindle axle sleeves；3- connectors；4- spindles.
Embodiment
During production line production smooth for steel rolling straightener, avoid aligning producing shake between roller shaft head and the spindle axle sleeve
It is dynamic, cause straight roller shaft head and spindle axle sleeve to disengage, the utility model provides a kind of straightener interference fit device, described device
Including：Align roller shaft head and spindle axle sleeve；Wherein, the endoporus of the aligning roller shaft head and the spindle axle sleeve is cylinder,
And described align between roller shaft head and the spindle axle sleeve is interference fit.
The technical solution of the utility model is described in further detail below by drawings and the specific embodiments.
The present embodiment provides a kind of straightener interference fit device, as shown in figure 1, described device includes：Align roller shaft head
1st, spindle axle sleeve 2, connector 3, spindle 4；
Wherein, the endoporus of the aligning roller shaft head 1 and the spindle axle sleeve 2 is cylinder, and the aligning roller shaft head 1
And between the spindle axle sleeve 2 for interference fit.
It is connected between the spindle axle sleeve 2 and the spindle 4 by the connector 3；Specifically, the connector 3 wraps
Two are included, is specifically as follows connecting bolt, after the endoporus of spindle axle sleeve 2 is connected with aligning roller shaft head 1, passes through connecting bolt
Spindle axle sleeve 2 and the spindle 4 are connected.
Here, the diameter of the aligning roller shaft head 1 and the bore inner diameter of the spindle axle sleeve 2 are 89mm, to cause
Stating aligning roller shaft head 1 smoothly can enter in the endoporus of the connecting bushing 2.Wherein, the material of the aligning roller shaft head 1 is
9Cr2Mo, yield strength limiting value are 900MPa.
Further, the interference fit length between the aligning roller shaft head 1 and the spindle axle sleeve 2 is 150mm.When upper
State after parameter all sets, to test the safety coefficient that roller shaft head 1 is aligned when logical interference fit transmits moment of torsion, it is specific as follows：
When establishing using interference fit, aligning roller shaft head 1 transmits the analysis model of moment of torsion with spindle axle sleeve 2, then to mould
Type carries out mesh generation, and mesh generation uses space hexahedron elemens, and has carried out mesh refinement setting in contact area.Division
During unit, 493418 nodes, 133703 units are obtained.
In above-mentioned model, magnitude of interference 0.146mm, when applying 4543N.m moment of torsion to the model, roller shaft head is aligned
CONTACT WITH FRICTION, coefficient of friction 0.1 are established between 1 and spindle axle sleeve 2, the aligning other end of roller shaft head 1 equally applies fixed constraint,
Obtain boundary condition model.It is 252.82MPa by the maximum equivalent value that aligning roller shaft head 1 is calculated.So can
Using calculate aligning roller shaft head 1 safety coefficient as：00/252.82=3.56.The safety coefficient can ensure that equipment can completely
