Description

Technical Field

[0001] The invention relates to the field of universal shafts, and in particular to a detachable trunnion support seat. Background Art

[0002] At present, the rolling mill equipment uses a drum gear universal shaft. Due to the relatively full production tasks and less downtime, the universal shaft is supported under the balancing device. The radial force under normal working conditions is large, especially when the process rolls are changed, the thrust of the traverse cylinder may cause the bearing seat ear shaft to break and be damaged. Due to the damage of the bearing seat ear shaft, the upper and lower universal shafts lose their relative position, resulting in a longer process roll change time. If it needs to be restored, the whole machine must be stopped for replacement, which is time-consuming and labor-intensive. In addition, the cost of replacing the whole bearing seat is relatively high.

[0003] Therefore, it is necessary to develop a new type of detachable trunnion support seat to overcome the above problems. Summary of the invention

[0004] Purpose of the invention: In view of the shortcomings and defects of the prior art, the present invention provides a detachable ear shaft support seat, which is suitable for equipment of wire rolling universal shaft. By replacing the ear shaft separately, the replacement time can be greatly reduced to meet the requirements of online replacement. The cost of replacing the ear shaft separately is significantly lower than that of replacing the entire original support seat.

[0005] Technical solution: A detachable ear shaft support seat of the present invention is characterized in that it includes an ear shaft, a support seat and bolts, the ear shaft and the support seat are detachable structures, both ends of the support seat are connected to the ear shaft, and the ear shaft and the support seat are connected by a plurality of bolts.

[0006] The ear shaft connection end is provided with a connecting plate with an arc-shaped structure that fits the support seat, the connecting plate is provided with a threaded hole, and the support seat is provided with a corresponding threaded hole.

[0007] Wherein, the bolts pass through corresponding threaded holes on the connecting plate and the supporting seat to connect and fix the ear shaft and the supporting seat.

[0008] Wherein, the connecting plate is connected to the supporting seat by means of 4 bolts, and the bolts are arranged in groups of 2 on both sides of the ear shaft.

[0009] Wherein, the ear shaft is provided with a protruding key structure, and the supporting seat is provided with a corresponding recessed keyway structure.

[0010] Wherein, the key structure is inserted into the keyway structure to connect and fix the ear shaft and the supporting seat.

[0011] Wherein, a double fixing structure is provided between the ear shaft and the supporting seat, and the double fixing structure includes a key structure, a keyway structure, and bolts.

[0012] When in use, the support seat and the ear shaft are made separately, the ear shaft and the support seat are connected by a key structure and bolts, and the keyway structure is matched and the bolts are locked and fixed, so that the ear shaft can be replaced separately when it is broken.

[0013] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: The detachable trunnion support seat of the present invention can achieve the purpose of online replacement when the trunnion of the universal shaft breaks, solving the problem of needing offline maintenance. It can save the cost of overall processing and manufacturing, and at the same time reduce the difficulty and time of maintenance. The present invention saves procurement costs, reduces the labor intensity of workers, and shortens maintenance time. BRIEF DESCRIPTION OF THE DRAWINGS
