Description
Technical field
The present invention relates to a kind of roller system, it has: roller, described roller comprise axle or the axle spare that is bearing on the supporting position; Form the roll body of the work circumference of roller, described roll body can be around the pivot center rotation; And electronic direct drive unit, the rotor of described electronic direct drive unit and stator are arranged between supporting position and the roll body along the direction of pivot center, and the invention still further relates to a kind of installation method for this roller.
Background technology
This roller system is known by DE 103 39 733 A1.In described roller system, the rotor of electric direct drive device is connected with the roller gudgeon regularly, and described roller gudgeon is with respect to the work circumference indentation of roller.The stator that keeps the annulus with respect to rotor of described electronic direct drive unit is arranged in the electric machine casing, and described electric machine casing is bearing in by means of own housing bearing on the axle of turning cylinder of restriction roller.In order to admit reagency, be provided with the torque support portion that is connected with frame, described torque support portion is crossed limit and is constituted flexible member for fear of machinery.
In this make of the direct drive unit with electric machine casing independent supporting structure on roller axle, and especially when stator is bearing on frame or the lathe regularly without independent supporting structure ground and therefore the torque support portion of formation is unnecessary separately, the installation of this roller system causes very large problem.Because rotor generally includes strong permanent magnet system.Based on described permanent magnet system, causing that powerful radial magnetic force, described radial magnetic force can cause rotor and stator to recline during in assembling between stator and the rotor.But this definitely will be avoided, and this is because because damage or damage can occur in this case for the stator that attraction is collided each other and rotor.In addition, the stator that has reclined each other and rotor are because very high attraction no longer can be by manually separated from each other.
Therefore, for example be well known that by being also referred to as " torque motor " and can be used as the electronic direct drive unit that the overall structure unit obtains, rotor and stator are connected to each other by clip (B ü gel), and described clip is guaranteed concentricity between rotor and the stator between transportation and installation period and therefore guaranteed to keep the annulus.In addition, by Siemens Company, also the built-in type torque motor Class1 FW6 as the roller driving device setting is well known that, annular space between stator and the rotor utilizes spacer film to fill, and described spacer film can be removed from rotor and stator after finishing installation and accurately centering.
Especially because the tight position relationship of change that often occurs in the situation of the roller system of electronic direct drive unit, often impossible is that will center clip or spacer film remove from rotor and stator after installing.That is to say, before carrying out assembling process, just must accurately locate stator and rotor.But this is impossible in the following cases, comprises that namely the supporting system at one of roller and its supporting position should be used for supporting stator and rotor, and it especially can be in frame or the lathe.Because, only have when just should not be between erecting stage implementation cost high be used for supporting the measure of described roller the time, described roller is in the radial direction supporting reliable enforcement the with completely assembling.
