[0003] Even if the machine base adopts ductile iron, due to cost considerations, the safety factor still cannot reach the level of 8 times or 10 times. The front bearing chamber of the machine base is the main force supporting place, and there are situations such as large stress and stress concentration. Possible risk of rupture, once a failure such as rupture occurs, serious personal and property injuries will occur

The invention discloses a fracture protection structure for an elevator traction machine, and relates to the field of elevators. The fracture protection structure of the elevator traction machine comprises a front main body frame and a rear machine base, the front main body frame and the rear machine base are provided with a front bearing and a rear bearing respectively, a main shaft and a brake wheel are assembled between the front bearing and the rear bearing, the outer surface of the main shaft is fixedly sleeved with the brake wheel, and the brake wheel is in transmission connection with a traction wheel; and the four supporting and protecting blocks are all arranged below the front main body frame and located below the traction wheel. According to the fracture protection structure of the elevator traction machine, due to the fact that the distance between the outermost edge of the traction wheel and the four supporting protection blocks is only about 3 mm, when the structure just falls, the structure is supported, the falling potential energy is reduced, impact on supporting protection is reduced, and meanwhile the personnel falling feeling and the impact feeling possibly existing in an elevator car are reduced.
Description
technical field [0001] The invention relates to the technical field of elevators, in particular to a break protection structure for an elevator traction machine. Background technique [0002] The current permanent magnet synchronous gearless elevator traction machine usually adopts a cantilever structure, and the main support is the front side bearing, which bears the shaft load. For a certain safety factor, the traction machine frame usually adopts ductile iron. [0003] Even if the machine base is made of ductile iron, due to cost considerations, the safety factor still cannot reach the level of 8 times or 10 times. The front bearing chamber of the machine base is the main force supporting place, and there are situations such as large stress and stress concentration. Possible risk of rupture, once a failure such as rupture occurs, serious personal and property injuries will occur.
