Technical Field
The utility model belongs to the technical field of universal joint, a novel six roller mill group final drive cross axle type universal joint of HC is related to.
Background
The novel HC rolling mill is a high-precision roll shape control rolling mill, and the roll system comprises six rolls, two working rolls, two middle pulling rolls and two supporting rolls, and is driven by the working rolls. Under the same condition, the smaller the roll diameter of the working roll, the smaller the rolling force and the better the cold-rolled sheet profile. In order to obtain a better cold-rolled product, a working roll with a small roll diameter needs to be selected as far as possible, so that a transmission device (a universal coupling) selects a shaft diameter as small as possible, otherwise, the two universal couplings collide with each other and cannot be used.
The universal coupling is a transmission device for connecting the working roll and the speed reducer by an HC six-roller mill, so that the two shafts are not on the same axis, the two connected shafts can continuously rotate under the condition of an included angle of the axes, and torque and motion can be reliably transmitted. The universal coupling is mainly formed by welding two cross shaft type universal joints with the same structure and a steel pipe, and the mechanical standard of the universal coupling is JB/T5513-2006.
In the above description, the universal joint is required to have as small a shaft diameter as possible, and the torsional strength is weak, so that the universal joint is frequently damaged.
Disclosure of Invention
The utility model discloses a remedy prior art not enough, provide a novel six roller mill group final drive cross axle type universal joint of HC, realized the torsional strength of reinforcing universal joint's one end cross axle universal joint. The utility model discloses a realize through following technical scheme: the utility model provides a novel six roller mill group final drive cross axle type universal joint of HC, its structure includes flange jaw, welding jaw and cross, the cross inserts in the shaft hole of flange jaw and welding jaw, flange jaw, welding jaw and cross constitute the half-coupling, half-coupling A and half-coupling B pass through connecting pipe fixed connection, half-coupling A and half-coupling B's model size is inequality.
Preferably, the shaft diameter of the half coupling A is smaller than that of the half coupling B.
Preferably, the coupling halves A and B are symmetrically arranged at two sides of the connecting pipe.
Preferably, the welding fork of the half coupling A and the welding fork of the half coupling B are connected with the connecting pipe in a welding mode.
