The following describes an cogging mill spindle balancer according to an embodiment of the present invention with reference to fig. 1 to 8.

Referring to fig. 1 to 8, the utility model discloses a cogging mill spiale balancing unit, including the first bearing that is used for installing spiale 100, the first bearing frame 101 that is used for installing the first bearing, the second bearing that is used for installing spiale 200 down, the second bearing frame 201 that is used for installing the second bearing, first drive arrangement 102 and second drive arrangement 202; the bottom of the first bearing seat 101 is provided with a first rotating seat 103, and the bottom of the second bearing seat 201 is provided with a second rotating seat 203; the bearing seat further comprises a first base 104 and a second base 204, wherein the first base 104 is arranged on the side of the first bearing seat 101, and the second base 204 is arranged on the side of the second bearing seat 201; the first base 104 is provided with a first base 105, and the second base 204 is provided with a second base 205; the first driving device 102 is mounted on the first base 105, and the second driving device 202 is mounted on the second base 205; the input end of the first transmission mechanism is in transmission connection with the first driving device 102, and the output end of the first transmission mechanism is in transmission connection with the first rotating seat 103; the input end of the second transmission mechanism is in transmission connection with the second driving device 202, and the output end of the second transmission mechanism is in transmission connection with the second rotating base 203.

As is known, the spindle of the cogging mill includes an upper spindle 100 and a lower spindle 200, and the upper spindle 100 is generally installed above the lower spindle 200. The utility model discloses a cogging mill spiale balancing unit, including the first bearing that is used for installing spiale 100, the first bearing frame 101 that is used for installing first bearing, be used for installing under the installation spiale 200 the second bearing, be used for installing second bearing's second bearing frame 201, first drive arrangement 102 and second drive arrangement 202. The first rotary seat 103 is installed at the bottom of the first bearing seat 101, and the second rotary seat 203 is installed at the bottom of the second bearing seat 201.

Wherein the first bearing is mounted on the first bearing housing 101 and the second bearing is mounted on the second bearing housing 201. The upper connecting shaft 100 penetrates through the first bearing inner ring and can rotate together with the first bearing inner ring; the lower spindle 200 passes through the second bearing cone and is rotatable together with the second bearing cone. In this embodiment, the first and second bearings are preferably split bearings, and the first and second bearing housings 101 and 201 are preferably split bearings, respectively.

The first rotary seat 103 is installed at the bottom of the first bearing seat 101, and the second rotary seat 203 is installed at the bottom of the second bearing seat 201. As shown in fig. 5 to 8, a groove 501 is formed at the bottom of the first bearing seat 101, and a pin 502 matching with the groove 501 is fixedly disposed at the top of the first rotating seat 103. The pin 502 is mounted in the groove 501 and can rotate within the groove 501 by a small amount. Meanwhile, the balancing device at the bottom of the first rotating base 103 applies upward supporting force to the first rotating base 103 to ensure that the pin 502 does not slip out of the groove 501. The reason for this is that when the spigots move along with the working rolls, a small-amplitude inclination occurs, and the matching of the pin shafts 502 and the grooves 501 can just adapt to the inclination of the spigots, so that the position has self-aligning capability, the spigots can not generate torque acting force on the balancing device when inclining, and the balancing device is protected from being damaged.

As shown in fig. 1, the first base 104 and the second base 204 are designed according to different heights of the upper spindle 100 and the lower spindle 200, and are formed by pouring reinforced concrete. Since the upper spindle 100 is located above the lower spindle 200, the first base 104 is correspondingly located higher than the second base 204. The first base 104 is arranged at the side of the first bearing seat 101 for balancing the force of the upper connecting shaft 100; the second base 204 is disposed at a side portion of the second bearing housing 201 for force-balancing the lower spindle 200. The first base 104 is provided with a first pedestal 105, and the second base 204 is provided with a second pedestal 205. The first driving device 102 is mounted on the first base 105, and the second driving device 202 is mounted on the second base 205.

Correspondingly, the first drive 102 is used for balancing the upper spindle 100, and the second drive 202 is used for balancing the lower spindle 200. The device is also provided with a first transmission mechanism and a second transmission mechanism, wherein the input end of the first transmission mechanism is in transmission connection with the first driving device 102, and the output end of the first transmission mechanism is in transmission connection with the first rotating seat 103. The input end of the second transmission mechanism is in transmission connection with the second driving device 202, and the output end of the second transmission mechanism is in transmission connection with the second rotating base 203. Therefore, the implementation process of the balance mode of the upper connecting shaft 100 is as follows: the hydraulic pressure of the first driving device 102 (preferably, the first hydraulic cylinder) acts on the first transmission mechanism, the first transmission mechanism transmits the acting force to the first rotating base 103, the pin 502 on the first rotating base 103 transmits the acting force to the first bearing base 101, and the first bearing base 101 directly acts on the upper connecting shaft 100. Similarly, lower spindle 200 is balanced in the same manner as upper spindle 100, except that another set of systems (shown in FIG. 1) corresponding to lower spindle 200 is used.

It should be noted that the balancing device adopts a hydraulic balance mode, and the effect of improving the transmission stability of the rolling mill is better because the hydraulic balance is more accurate and stable relative to the mechanical balance.
