Described small arc-shaped plate 10 is evenly distributed with some radial directions location unthreaded hole 14, the screwed hole that offer step corresponding with described radial direction location unthreaded hole 14 on the axial end that roller 2 diameter is less, it is provided with soket head cap screw 12 in this place's screwed hole, the inner end of this place's soket head cap screw 12 stretches into and radially positions in unthreaded hole 14, thus preventing quick change shell 3 from moving in radial directions, it is prevented that stick up outside quick change shell 3；
Corresponding with described connecting plate 11 on the axial end that roller 2 is relatively large in diameter it is provided with breach 15；Breach 15 is convenient to installation and removal connecting plate 11, couples together by two orthodrome plates 9 or is separated by two orthodrome plates 9.
The lateral surface pressure of described self-aligning bearing 4 is provided with roller end cap 16, and roller end cap 16 and roller 2 are bolted to connection, and are provided with rotary shaft lip seal 17 and rubber dust-proof sealing ring 18 between roller end cap 16 and roll spindle 1.
Described left semicircle cone shell 7 includes the splice plate 19 of some fan annulars, and described some splice plates 19 are welded together to form described left semicircle cone shell 7 by described orthodrome plate 9 and described small arc-shaped plate 10；Between contiguous concatenation plate 19, there is gap；The structure of described right semi-circle cone shell 8 is identical with the structure of left semicircle cone shell 7.Between contiguous concatenation plate 19, there is gap, the stress influence in milling process can be reduced.
The invention also discloses the method that the described novel grinding roller with quick change shell changes quick change shell, sequentially include the following steps: successively
First step is that the soket head cap screw 12 of orthodrome plate 9 and small arc-shaped plate 10 place is unscrewed and taken off, orthodrome plate 9 and small arc-shaped plate 10 is made all to be separated with corresponding soket head cap screw 12, again the soket head cap screw 12 at connecting plate 11 place is unscrewed and takes off, take down connecting plate 11, then the left and right half-conical housing 7,8 of old quick change shell 3 is taken off；
Second step is that the orthodrome plate 9 of the left and right half-conical housing 7,8 of new quick change shell 3 is inserted big annular groove 5 respectively, and the small arc-shaped plate 10 of the left and right half-conical housing 7,8 of new quick change shell 3 is inserted little annular groove 6 respectively, left and right half-conical housing 7,8 is installed on roller 2, and in the unthreaded hole of the screwed hole 13 of orthodrome plate 9 and small arc-shaped plate 10, puts into soket head cap screw 12 respectively at two axial end places of roller 2；
Third step is to be fixed together by left and right half-conical housing 7,8 with connecting plate 11 and soket head cap screw 12；
4th step is to tighten each soket head cap screw 12, can be installed by new quick change shell 3.
Cinching process during installation: the unthreaded hole on soket head cap screw 12 traverse roller 2 and the screwed hole 13 on the orthodrome bar of quick change shell 3, the head of a nail of soket head cap screw 12 is stuck in the step place of stepped hole, thus will not be subjected to displacement (namely will not move to the right shown in Fig. 1) in the axial direction again.Continuing to turn soket head cap screw 12, owing to soket head cap screw 12 is not axially having displacement, therefore orthodrome plate 9 drives the axial end that quick change shell 3 is relatively large in diameter to roller 2 to move, and quick change shell 3 just can be close to above roller 2.
The installation method first of quick change shell 3 is:
Step one: by self-aligning bearing 4, roller 2, rotary shaft lip seal 17, roller end cap 16, rubber dust-proof sealing ring 18 is sequentially arranged in roll spindle 1 and fixes；
Step 2: described orthodrome plate 9 is inserted big annular groove 5, described small arc-shaped plate 10 is inserted little annular groove 6, left and right half-conical housing 7,8 is installed on roller 2, and in the unthreaded hole of the screwed hole 13 of orthodrome plate 9 and small arc-shaped plate 10, puts into soket head cap screw 12 respectively at two axial end places of roller 2；
Axially position inner hex screw 12, orthodrome plate 9 and big annular groove 5, radially position inner hex screw 12, small arc-shaped plate 10 and little annular groove 6；
Step 3: left and right half-conical housing 7,8 is fixed together with connecting plate 11 and soket head cap screw 12；
Step 4: tighten each soket head cap screw 12, can install quick change shell 3.
The method take off old quick change shell 3, more renewing quick change shell 3 is:
First step is that the soket head cap screw 12 of orthodrome plate 9 and small arc-shaped plate 10 place is unscrewed and taken off, orthodrome plate 9 and small arc-shaped plate 10 is made all to be separated with corresponding soket head cap screw 12, again the soket head cap screw 12 at connecting plate 11 place is unscrewed and takes off, take down connecting plate 11, then the left and right half-conical housing 7,8 of old quick change shell 3 is taken off；
Second step is that the orthodrome plate 9 of the left and right half-conical housing 7,8 of new quick change shell 3 is inserted big annular groove 5 respectively, and the small arc-shaped plate 10 of the left and right half-conical housing 7,8 of new quick change shell 3 is inserted little annular groove 6 respectively, left and right half-conical housing 7,8 is installed on roller 2, and in the unthreaded hole of the screwed hole 13 of orthodrome plate 9 and small arc-shaped plate 10, puts into soket head cap screw 12 respectively at two axial end places of roller 2；
Third step is to be fixed together by left and right half-conical housing 7,8 with connecting plate 11 and soket head cap screw 12；
4th step is to tighten each soket head cap screw 12, can be installed by new quick change shell 3.
Above example is only in order to illustrative not limiting technical scheme, although the present invention being described in detail with reference to above-described embodiment, it will be understood by those within the art that: still the present invention can be modified or equivalent replacement, without deviating from any modification or partial replacement of the spirit and scope of the present invention, it all should be encompassed in the middle of scope of the presently claimed invention.
