Definitions

• the subject invention relates to a steering wheel with two rollers, wherein a first roller is arranged substantially stationary and a second roller against the first roller and arranged with two pivotable rockers, in which the second roller gela ⁇ siege, and in which Pivoting the rockers each a pressure medium cylinder is arranged.
• Steering drivers are typically used in rolling mills, where they are arranged in front of rolled strip hooks in order to set the strip tension in front of the reel by means of two rolls. Another object of the steering operator is to prevent lateral wandering of the Walzban ⁇ before rewinding.
• a pivotable roller is triggered and actuated against a stationary roller such that the position of this roller relative to the stationary roller causes the rolled strip to undergo a desired strip tension and a desired lateral displacement.
• Such a steering driver goes e.g. from EP 192 982 B1 or DE 26 15 254 A1, which show a driver whose pivotable roller is mounted in a continuous rocker.
• the steering actuator can be very easily built and it It is not necessary to take account of mutual influences on interconnected rockers, which makes the steering driver very simple and, above all, precisely controllable.
• the rockers are mounted at one of their ends on the frame and is arranged in each case at the other end of the pressure cylinder and arranged between the two ends of the rockers, the bearing of the second roller, as there are, inter alia, favorable leverage.
• a particularly preferred embodiment is obtained by arranging an axle rotatably mounted on the frame and one of the two wings rigidly connected to this axis, which can be further improved by the second rocker is pivotally connected to the axle.
• the constructional structure is thereby simplified, since only a single axis is required in order to support both rockers rotatably independently of each other.
• the reliability of the steering actuator is increased when a Verschwenk Kli ⁇ is seen to prevent a rocker is pivoted too far and thereby parts of the steering drive or the rocker, e.g. a bearing or seal could be damaged or destroyed.
• the bearing of the roller and the bearing of the rocker is arranged in a line, so that no Kipp ⁇ moment arises by the actuation force of the actuator.
• the steering driver according to the invention is described below with reference to the exemplary non-limiting Figure 1, which shows such a steering driver in three-dimensional An ⁇ view.
• the steering actuator 1 in FIG. 1 consists essentially of a frame 12, in which a first roller 6 is mounted here in a storage 8 substantially stationary. Stored here means that although the roller can rotate, it has essentially no further degrees of freedom with respect to the frame 12.
• a second roller 5 is rotatably mounted in a further bearing 7 and is arranged to be adjustable relative to the first roller 6, so it can be moved relative to the first roller 6.
• two rockers 2, 3 are provided, which are arranged pivotably about an axis of rotation 13 on the frame.
• the second roller 5 is rotatably mounted in the bearing 7 and at the free end of the rockers 2, 3 is in each case an actuator 4, such as here a pressure medium cylinder, preferably a hydraulic cylinder arranged.
• the rockers 2, 3 are mounted separately and independently movable on the frame 12.
• an axle 9, for example a tube is supported rotatably on the frame 12 in two bearings 10, here for example roller bearings, for example a roller bearing or spherical roller bearing.
• roller bearings for example a roller bearing or spherical roller bearing.
• the second rocker 2 is rotatably arranged on the axle 9 by means of a bearing 11, here again a Wälz ⁇ .
• the two rockers 2, 3 can therefore be moved completely independently of each other.
• the two wings 2, 3 each in a suitable manner pivoted on its own axis connected to the frame or its own pin, wherein the rocker 2, 3 fixedly connected to the axis or the pin or stored on this could be, or store directly on the frame 12.
• an axis could be rigidly arranged on the frame 12, on which the rockers 2, 3 could be mounted pivotably.
• the pressure medium cylinder 4 is fastened here in each case to the frame 12 with one end on the rockers 2, 3 and with its other end, so that the second roller 5 is pivoted about the axis of rotation 13 by applying the pressure medium cylinder 4 and relative to the first roller ze 6 can be moved.
• the point of application of the pressure cylinder 4, the bearing 7 of the roller 5 in the rocker 2, 3 and the bearing 11 of the rocker 2 on the axis 9 and the rigid connection between rocker 3 and axis 9 is preferably arranged in each case in a line, so No tilting moments are caused in the rockers 2, 3 by the forces exerted by the pressure medium cylinder 4.
• the pressure cylinder 4 could also be attached to a laterally projecting projection of the wings 2, 3.
• the spring assembly 14, which is in each case arranged between the rockers 2, 3 and the bearing 16 of the Fe ⁇ derpers 14, essentially serves to pull the bearing 7 of the roller 5 upwards, so as to eliminate the bearing clearance or at least out. This should be avoided impacts on the bearing 7 of the second roller 5 when retracting the belt between the rollers 5, 6.
• a Verschwenk puzzle 15 may be provided to limit the pivotal movement of the pivotable about the axis 9 rocker 2. This prevents that in the case of a malfunction a permissible Schwenk ⁇ angle, for example, the bearing or a seal can not be exceeded.
• the pivot lock 15 can be designed in such a way that two hinges are provided on the axle 9, which define the limits of the pivoting movement, between which Another, with the rocker 2 connected and mitbetaineder stop be ⁇ moves.
• the steering actuator 1 is already well known from the prior art and therefore need not be described in detail.
• the strip tension and lateral movement can be adjusted by the Lenk ⁇ driver 1, in which the rockers 2, 3 are pivoted by the pressure cylinder 4 and so the second roller 5 in a desired manner against the first roller 6 is turned on.
• the pressure cylinder 4 are to be controlled accordingly and a corresponding regulation is optionally provided.
