Background
The rolling device suitable for the ultra-large-diameter steel pipe is particularly necessary, most of the existing large-diameter sizing mills only have one transmission mechanism, and once the transmission mechanism fails, the whole large-diameter sizing mill cannot normally work, so that the production progress of the steel pipe is influenced. There is therefore a need for a rolling mill that can be driven individually, and no matter which of the multiple drives fails, the remaining drives can still function properly to drive the sizer to roll the steel tube.
Disclosure of Invention
The utility model discloses a solve above problem and provide a compact structure, independent transmission, job stabilization, reduction fault rate, wide heavy-calibre sizing mill independent transmission of application scope.
The technical scheme of the utility model is that: an individual transmission device of a large-diameter sizing mill comprises a pull rod, a main transmission connecting sleeve, a transmission spline sleeve, a gland, a long positioning sleeve, a transmission shaft, a short positioning sleeve, a bearing long sleeve cup, a bearing, a roller, a spline sleeve and a bearing short sleeve cup,
the main transmission connecting sleeve is connected with an external power mechanism and is driven to rotate by the external power mechanism, the bearing is arranged outside the transmission shaft, the transmission shaft is supported in a rotating mode, the long positioning sleeve is arranged outside the bearing and is used for positioning an outer ring of the bearing, the short positioning sleeve is positioned outside the bearing and is used for positioning an inner ring of the bearing, a gland is arranged outside the long positioning sleeve and is fixed through the gland, a sealing ring is arranged on the inner ring of the gland, the transmission spline sleeve is connected in the main transmission connecting sleeve through a bolt and rotates along with the main transmission connecting sleeve, the transmission spline sleeve is connected with the transmission shaft through a spline, the transmission shaft is connected with the spline sleeve through a spline, and the roller is in interference fit with the spline sleeve and rotates along with the spline sleeve.
Furthermore, the transmission device of the large-caliber sizing mill is composed of three independent transmission devices, and the three independent transmission devices have the same structure.
Furthermore, the internal spline of the transmission spline housing is meshed with the external spline of the transmission shaft.
Furthermore, the external spline of the transmission shaft is meshed with the internal spline of the spline housing.
Further, the pull rod transversely penetrates through the single transmission device and is used for shrinking the gap during assembly.
The utility model has the advantages that: 1. the three sets of transmission devices are respectively and independently driven by the three power devices, and even if one set of transmission device has problems, the other two sets of transmission devices can also work normally without influencing the production progress of the steel pipe; 2. because the product is formed by combining various parts, accumulated gaps exist during assembly, and the gap can be contracted by rotating the pull rod after the assembly is finished; 3. the structure is compact, the transmission is independent, the work is stable, and the failure rate is reduced; 4. the application range is wide, the product is suitable for rolling large-caliber steel pipes, and the rolling range is phi 508-phi 711.
