DETAILED DESCRIPTION

[0016] The present invention will be further described below through examples in conjunction with the accompanying drawings.

[0017] A shock-resistant dual-output shaft roller table comprises a dual-output shaft roller 6, a bearing seat locating sleeve 7, a bearing pressure cover 8, a bearing 9, a bearing seat 10, a bearing locating sleeve 11 and a spacing locating sleeve 12. Output shafts are provided at both ends of the dual-output shaft roller 6. Bearing seats 10 are installed on the output shafts. Bearings 9 are arranged in the bearing seats 10. Bearing locating sleeves 11 are respectively installed on both sides of the bearings 9 in the bearing seats 10. Bearing pressure covers 8 are respectively installed on both sides of the bearing seats 10 and fastened by bolts; a bearing seat locating sleeve 7 and a spacing locating sleeve 12 are provided between the output shaft and the bearing seat 10, and the bearing 9 is arranged on the output shaft between the bearing seat locating sleeve 7 and the spacing locating sleeve 12; a coupling connecting shaft 13 is provided at the end of the output shaft, and the spacing locating sleeve 12 is arranged close to the coupling connecting shaft 13.

[0018] The bearing locating sleeve 11 and the bearing pressure cover 8 on one side of the bearing 9 are arranged on the bearing seat locating sleeve 7 , and the bearing locating sleeve 11 and the bearing pressure cover 8 on the other side are arranged on the spacing locating sleeve 12 .

[0019] A baffle plate 14 is disposed on the outer side of the bearing gland 8 on the other side of the bearing 9 , and the baffle plate 14 is disposed on the spacing and positioning sleeve 12 .

[0020] The diameter of the coupling connecting shaft 13 is 105 mm.

[0021] The coupling connecting shaft 13 is connected to the coupling 3 , the coupling 3 is connected to the reducer 2 , and the reducer 2 is connected to the motor 1 .

[0022] When installing the utility model, first assemble the bearing seat 10, put the bearing 9 into the bearing seat 10, install the bearing locating sleeves 11 on both sides of the bearing 9, install the bearing gland 8 after installing the bearing locating sleeves 11, and fasten the bearing gland 8 in place with bolts; then assemble the roller 4, install the bearing seat locating sleeve 7 on the output shaft of the double output shaft roller 6, continue to install the assembled bearing seat 10, and finally install the spacing locating sleeve 12 on the output shaft of the double output shaft roller 6, then install the baffle 14 on the spacing locating sleeve 12, and fix it with the bearing gland 8 by bolts. The output shafts at both ends of the double output shaft roller 6 have the same structure, and both ends of the double output shaft roller 6 are assembled, that is, the assembly of the utility model is completed.

[0023] The roller table 4 of the utility model relies on the motor 1 to drive the reducer 2, and the reducer 2 drives the roller table 4 to rotate through the coupling 3, and the blank 5 is transported to the rolling mill for processing through the roller table 4.

Even if one end is broken, it can still be used normally after rotating 180 degrees, which improves production efficiency and reduces the maintenance cost of the roller table equipment.

[0024] The utility model improves the impact resistance of the working roller, prevents the roller from breaking at the root of the coupling connecting shaft, reduces the failure rate of the roller equipment, and improves production efficiency. Through on-site investigation, it is found that the working roller breaks after the weight of the billet increases. The original billet weight is 10 tons at most, and the current billet weight is 13 tons at most. After measurement, the root diameter of the broken output shaft is 95mm. According to the impact force calculation formula: Ft=mv2-mv1, the output shaft with a diameter of 95mm cannot meet the current production needs. The output shaft diameter can be increased to 105mm to improve the impact resistance of the working roller. At the same time, a double output shaft structure is adopted. Even if the root of the connecting shaft at one end is broken, the roller can continue to be used after rotating 180 degrees, thereby improving the reuse rate of the roller and reducing the equipment maintenance cost.
