Embodiment Construction
[0025] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings.
[0026] Such as figure 1 As shown, the split type dynamic pressure oil film bearing 1 for the laying head (referred to as the oil film bearing) is arranged on the output shaft 2 of the laying head, and the split type dynamic pressure oil film bearing 1 for the laying head includes: The bearing surface 11 of the tile-shaped semi-circular ring and the non-bearing surface 12 of the tile-shaped semi-circular ring, the bearing surface 11 and the non-bearing surface 12 are all provided with oil wedges and oil inlet holes communicated with the oil wedges , the non-bearing surface 12 is also provided with an oil return port 123 . Such as figure 2 and image 3 As shown, the oil film bearing 1 is divided into two tile-shaped semicircula...

The invention provides a split dynamic pressure oil film bearing for a silking machine, which is arranged at the output shaft of the silking machine and includes a bush-shaped semi-annular bearing surface and a bush-shaped semi-annular non-bearing surface that are connected, wherein oil wedges and oil inlets that are communicated with the oil wedges are arranged on both the bearing surface and the non-bearing surface; and an oil return port is arranged on the non-bearing surface. By adopting the split fixed bush structure, the split dynamic pressure oil film bearing has a simple pattern, is easy to realize, and is lower in cost; and the bigger openings of the oil wedges in the oil film bearing facilitate the diffusion of the lubricating oil in the oil cavity, the lubricating oil has big flow rate and small oil resistance, the big oil return port on the non-bearing surface facilitates the oil return, the temperature rise of the lubricating oil is lower, and the split dynamic pressure oil film bearing is more suitable for the high-speed work condition.
Description
technical field [0001] The invention relates to the field of steel rolling machinery, in particular to a high-speed wire laying machine, in particular to a split type dynamic pressure oil film bearing for the laying machine. Background technique [0002] The wire laying machine is an important equipment in the high-speed wire rod production line unit. When the wire laying machine works, it bends the continuous straight rolling material passing through it into a circular rolling material. The main components of the laying machine include: motor, input shaft and gear, output shaft and gear, spinning head, spinning tube, spinning disc, safety cover, etc. Its main structure is: the motor transmits the rotary motion from the input shaft to the output shaft of the laying machine through a pair of spiral bevel gears, the spinning head is connected with the output shaft and rotates together, and the spinning tube is fixed on the spinning head . The steel rolled and formed by the h...
