Abstract
The invention provides a steel rolling equipment four-head quincunical sleeve. The sleeve is characterized in that the length L is 1.2-1.5, d is the diameter of a spindle wabbler, the wall thickness S of the middle part of the sleeve is equal to (0.18-0.2)d, the outer diameter D of the middle part of the sleeve is d1+2S, d1 is the diameter of a quincunical hole of the sleeve and is equal to (1+7%)d, the diameter d2 of a line formed by quincunical radius and the center of a circle is d1+7%d, the quincunical radius r is 0.2d, and the distance t formed by the quincunical radius and the center of the circle is 3.5%d.
Description
Technical field
A kind of design, especially the four-head coupling box endoporus of the coupling box that the open steel rolling equipment of the present invention is used protrudes the method for designing of plum blossom part, and gap feasible and plum-blossom connecting shaft is even, and roll change is convenient.
Background technology
Coupling box claims the plum blossom axle sleeve again, is to be used between plum-blossom connecting shaft and the roll, transmits the moment of torsion of motor output on the mill train direction and supplies with roll.At three roll shape steel and rod-rolling mill, two roll shape steel (continous way) milling trains, jobbing sheet-rolling mill, on the two roller sheet mills application is arranged all.
At present, a lot of steel rolling equipments design the major parameter design formula that mechanical data has only provided coupling box, the diameter of the middle part wall thickness of the length of coupling box, sleeve and sleeve plum blossom hole for example, and do not have the carrying out of system for the one-tenth Series Design of sleeve plum blossom hole plum blossom.
Summary of the invention
In order to overcome this deficiency, the present invention has provided a kind of complete design of coupling box.
The design parameter of coupling box can be determined by following proportionate relationship.
1) length sleeve L is
L＝(1.2～1.5)d------------------------(1)
In the formula: d---connect a wabbler diameter, mm
2) sleeve middle part wall thickness S is
S＝(0.18～0.2)d------------------------(2)
3) sleeve middle part outer diameter D is
D＝d
1+2S-------------------------------(3)
In the formula: d1---the diameter of sleeve plum blossom hole.
4) sleeve plum blossom hole diameter d 1 is
d
1＝(1+7％)d--------------------------(4)
5) plum blossom radius center of circle structural line diameter d 2 is
d
2＝d
1+7％d----------------------------(5)
6) the plum blossom radius r is
r＝0.2d------------------------------(6)
7) plum blossom radius center of circle structure spacing t is
t＝3.5％d-----------------------------(7)

The specific embodiment
Below in conjunction with accompanying drawing design of the present invention is further described.
Fig. 1 is that front view is cutd open at the coupling box center.Provided the length L and the sleeve middle part wall thickness S of coupling box among the figure, both have all provided a span, can be according to the actual conditions value of plum-blossom connecting shaft and roll.After sleeve middle part wall thickness S determined, the outer diameter D at sleeve middle part was also determined thereupon.
Fig. 2 is the cutaway view of A-A among Fig. 1.Can determine the diameter d 1 of plum blossom hole according to formula (4), be the center of circle with the center of circle of plum blossom hole diameter, determines the diameter d 2 of plum blossom radius center of circle structural line according to formula (5).Be basic point with center of circle O then, one group of new center line is done in 45 ° of center line rotations, and former center line keeps, and determines plum blossom radius structure spacing t according to formula (7), with the ranging offset center line l of t/2, hands over circle and A, B 2 points respectively.Determining the plum blossom radius r with formula (6) again, is that the plum blossom radius is done in the center of circle with 2 of A, B respectively, and so far, a plum blossom configuration design in the sleeve is finished.Determine its excess-three plum blossom in the sleeve with same method, so far, the design of a complete coupling box is finished.
Fig. 3 is to be example with d=280, the installation diagram of plum-blossom connecting shaft and coupling box, and the radial clearance of plum-blossom connecting shaft and coupling box is even substantially.
This each specification of coupling box series is as shown in table 1.
