The three-gear input gear shaft 31, the three-gear intermediate gear shaft 32 and the three-gear output gear shaft 33 are supported by the mounting bracket 2, which effectively reduces the span and improves the service life.

[0034] Example

[0035] like Figure 5-7As shown, when 11 straightening rollers are driven, when 4 of the straightening rollers are small roller systems and 7 are large roller systems, the output end of the motor group is connected to the 9 transmission mechanisms 5 through a coupling, and after being decelerated by the transmission mechanism 5, the torque is transmitted to the 7 three-gear input gear shafts 31 and the 2 four-gear input gear shafts 41 through the output end, and the three-gear input gear shaft 31 transmits the output torque to the three-gear output gear shaft 33 through the three-gear intermediate gear shaft 32 to provide straightening force for one large roller system, and the four-gear input gear shaft 41 transmits the output torque to the first four-gear output gear shaft 43 and the second four-gear output gear shaft 44 through the four-gear intermediate gear shaft 42 to provide straightening force for the two small roller systems. When performing maintenance or replacement, the mounting bracket 2 can be removed from the gear box body 1, and the maintenance and replacement can be performed by separating the transmission mechanism 5 from the mounting bracket 2.

[0037] It should be noted that, in this article, unless otherwise clearly specified and limited, the term "connection" or its synonyms should be understood in a broad sense. For example, "connection" can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. Moreover, expressions such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
