Description
Technical field
The present invention relates to the pilger mill apparatus field, particularly a kind of novel cycle roll roller case and bearing shell.
Background technology
At present, when pilger mill is worked, because the rolled piece relative deformation is bigger, top and bottom rolls is subjected to great draught pressure and impact force action, cause the bearing shell that plays the support effect between roll and roller case to be subjected to great draught pressure and impulsive force too, as Fig. 1, shown in Figure 2, mating surface between existing cycle roll roller case and the bearing shell is that a bottom surface and two are parallel to each other, and side perpendicular to the bottom surface, after long-time use, wearing and tearing and distortion will take place in bearing shell, after bearing bush abrasion reaches service life, owing to the bearing shell distortion sticks together bearing shell and roller case, when changing, need bearing shell and roller case be separated, waste time and energy with specific hydraulic roller case bearing shell disassembly mechanism.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, provide a kind of and be easy to make that bearing shell separates with the roller case, easy accessibility, can save the novel cycle roll roller case and the bearing shell of cost again.
Purpose of the present invention is achieved through the following technical solutions: novel cycle roll roller case and bearing shell, it comprises top roll case and lower roll case, the top roll case is vertically installed in the top of lower roll case, be provided with the top bearing shell A and the lower bearing A that cooperatively interact in the lower roll case, the end axle A of cycle roll A is located at the manhole A that the negative camber B of the negative camber A of lower bearing A and top bearing shell A forms, top bearing shell A top is provided with bearing shell lid A, bearing shell lid A by bolting on the lower roll case; Be provided with the lower bearing B and the top bearing shell B that cooperatively interact in the top roll case, the end axle B of cycle roll B is located at the negative camber C of lower bearing B and the manhole B that top bearing shell B negative camber D forms, top bearing shell B bottom is provided with bearing shell lid B, bearing shell lid B by bolting on the top roll case.
The lower roll case is provided with a wedge shape groove A, and two lozenges of wedge shape groove A are lozenges A and lozenges B, and during lower roll case horizontal positioned, the level interval of lozenges A and lozenges B is wide at the top and narrow at the bottom; The outer surface of lower bearing A is provided with lozenges C and lozenges D, lozenges C and the lozenges D cooperation that contacts with lozenges A and lozenges B respectively.
The top roll case is provided with a wedge shape groove B, and two lozenges of wedge shape groove B are lozenges E and lozenges F, and the level interval of lozenges E and lozenges F is up-narrow and down-wide; The outer surface of lower bearing B is provided with lozenges G and lozenges H, lozenges G and the lozenges H cooperation that contacts with lozenges E and lozenges F respectively.
The angle angle of described lozenges A and lozenges C and horizontal plane is identical, the angle angle of lozenges B and lozenges D and horizontal plane is identical, the angle angle of lozenges E and lozenges G and horizontal plane is identical, the angle angle of lozenges F and lozenges H and horizontal plane is identical.
Described lower bearing A is all identical with lower bearing B physical dimension.
The present invention has the following advantages:
1, not influencing the weight that has alleviated bearing shell on the bearing shell intensity based, saved cost.
When 2, after bearing bush abrasion reaches service life, needing to change,,, only need slight vibrations, bearing shell is separated with the roller case because the mating part of bearing shell and roller case is a wedge structure though distortion has taken place bearing shell.
3, bearing shell and roller case easy accessibility do not need specific hydraulic roller case bearing shell disassembly mechanism.

The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing:
As shown in Figure 3, Figure 4, novel cycle roll roller case and bearing shell, it comprises top roll case 16 and lower roll case 1, top roll case 16 is vertically installed in the top of lower roll case 1, be provided with the top bearing shell A2 and the lower bearing A3 that cooperatively interact in the lower roll case 1, the end axle A15 of cycle roll A14 is located at the manhole A11 that the negative camber B10 of the negative camber A9 of lower bearing A3 and top bearing shell A2 forms, and top bearing shell A2 top is provided with bearing shell lid A12, and bearing shell lid A12 is fixed on the lower roll case 1 by bolt 13; Be provided with the lower bearing B18 and the top bearing shell B17 that cooperatively interact in the top roll case 16, the end axle B29 of cycle roll B28 is located at the negative camber C24 of lower bearing B18 and the manhole B26 that top bearing shell B17 negative camber D25 forms, top bearing shell B17 bottom is provided with bearing shell lid B27, and bearing shell lid B27 is fixed on the top roll case 16 by bolt 13.Lower roll case 1 is provided with a wedge shape groove A4, and two lozenges of wedge shape groove A4 are lozenges A5 and lozenges B6, and during lower roll case 1 horizontal positioned, the level interval of lozenges A5 and lozenges B6 is wide at the top and narrow at the bottom; The outer surface of lower bearing A3 is provided with lozenges C7 and lozenges D8, lozenges C7 and the lozenges D8 cooperation that contacts with lozenges A5 and lozenges B6 respectively; Top roll case 16 is provided with a wedge shape groove B19, and two lozenges of wedge shape groove B19 are lozenges E20 and lozenges F21, and the level interval of lozenges E20 and lozenges F21 is up-narrow and down-wide; The outer surface of lower bearing B18 is provided with lozenges G22 and lozenges H23, lozenges G22 and the lozenges H23 cooperation that contacts with lozenges E20 and lozenges F21 respectively.The angle of lozenges A5, lozenges B6, lozenges C7, lozenges D8, lozenges E20, lozenges F21, lozenges G22, lozenges H23 and horizontal plane is 82 °, and lower bearing A3 is all identical with lower bearing B18 physical dimension, can be general mutually.
The course of work of the present invention is as follows: during installation, the lozenges C7 of lower bearing A3 and the lozenges D8 cooperation that contacts with the lozenges A5 of lower roll case 1 and lozenges B6 respectively, the end axle A15 of cycle roll A14 is installed in the negative camber A9 of lower bearing A3, top bearing shell A2 matches with lower bearing A3, bearing shell lid A12 compresses top bearing shell A2, and bearing shell lid A12 is fixed on the lower roll case 1 by bolt 13, same method, the lozenges G22 of lower bearing B18 and the lozenges H23 cooperation that contacts with the lozenges E20 of top roll case 16 and lozenges F21 respectively, the end axle B29 of cycle roll B28 is installed in the negative camber C24 of lower bearing B18, top bearing shell B17 matches with lower bearing B18, bearing shell lid B27 compresses top bearing shell B17, and bearing shell lid B27 is fixed on the top roll case 16 by bolt 13.
When after bearing bush abrasion reaches service life, needing to change, though distortion has taken place in bearing shell, but because lower bearing A3 and the mating part of lower roll case A1 and the mating part of lower bearing B18 and top roll case 16 are wedge structure, only need slight vibrations, bearing shell is separated with the roller case.
