Description

Technical Field

[0001] The utility model relates to the technical field of bow-twister machines, in particular to a bow-twister machine bearing seat with a cooling mechanism. Background Art

[0002] Bow twisting machine is a machine that completes the twisting action to manufacture stranded wire by the synchronous rotation of several rotating bows arranged in a straight line. Each rotating bow rotates around a floating basket of a pay-off reel and can be used for stranding wire or cabling. Wire twisting is achieved by the rotation of twisted single wires around the stranding axis at equal angular velocity and the forward movement of the stranded wire at a uniform speed. Copper and aluminum are commonly used. Copper and aluminum wires can be twisted into conductor cores of various specifications and cross-sections and different types of wires and cables. They are suitable for occasions with high operating frequencies and excessive skin effect and proximity effect losses of single-strand wires. The use of stranded wires can reduce the operating temperature. Compared with single-strand wires of the same cross-sectional area, stranded wires have higher mechanical properties and flexibility.

[0003] When the existing bow winch is in use, its main shaft always keeps the load axial rotation, so the main shaft is greatly worn, which can easily lead to unstable use. In addition, when there is a lack of lubrication or the load is large or the operation is long, the main shaft on the inside of the bearing seat is located inside the bearing seat, so the heat dissipation performance is poor, which can easily lead to overheating of the structure and reduce the service life of the structure.

After the cooling oil is added to the inside of the bearing seat structure 3 through the top cover 6, the main shaft 2 in direct contact can be cooled down to improve the heat dissipation efficiency of the main shaft 2, and the oil will contact the bearings in the seal to lubricate the bearings, avoiding the reduction of the service life of the main shaft 2 due to long-term wear. The coolant is extracted by the circulating pump 9 and then injected into the heat exchanger 8 for cooling, and then re-filled into the inside of the bearing seat structure 3 to circulate the cooling oil.

[0023] As a technical optimization solution of the present invention, a filter cover 10 is installed at the bottom of the top cover 6 , and the filter cover 10 is arranged on the inner side of the bearing seat structure 3 .

[0024] In this embodiment, by providing the filter cover 10, when the oil is added into the bearing seat structure 3 through the top cover 6, the cooling oil can be easily filtered to avoid impurities from contaminating the structure.

[0025] As a technical optimization solution of the utility model, a liquid inlet hole 11 is opened on the left side of the bearing seat structure 3, and a liquid discharge hole 12 is opened on the right side of the bearing seat structure 3.
