[0014] See also Figures 2 to 4 The invention discloses a spun rope pulley for an elevator tensioning device, comprising a rope pulley body 1 of an annular structure, wherein the rope pulley body 1 is an integrally spun rope pulley body 1, an integrally spun wheel groove 101 is provided on the outer periphery of the rope pulley body 1, a bearing seat mounting hole 103 is provided at the center of the rope pulley body 1, and a stamping groove 102 is provided on the annular surface of the rope pulley body 1, and the stamping groove 102 can play a role in strengthening the strength.

[0015] The stamping groove 102 is a wave-shaped structure.

[0016] The rope pulley body 1 is formed by spinning a metal plate into a structure with a thin inner circle and a thick outer circle through a spinning process.

[0017] In this embodiment, the wheel groove 101 of the rope pulley body 1 is integrally formed by spinning a metal plate, and the metal plate can be a steel plate or a steel alloy plate; the stamping groove 102 on the rope pulley body 1 has a wave-shaped three-dimensional enhanced stamping feature, and according to the force analysis, the stamping plane feature may not be required;

[0018] The bearing support seat is fixed inside the bearing seat mounting hole 103 by welding.

[0019] The working principle of the utility model is: cutting by laser cutting, and then using spinning equipment to process the metal sheet into shape, the spinning deformation makes the metallographic structure more uniform and dense than the cast state; and the material utilization rate is high, the processing efficiency is high, the production cost is low, the product economy is improved, the service life of the spinning parts is extended, and the quality of the finished product is reduced. After the rope pulley body 1 is processed, the bearing support seat is fixed to the inside of the bearing seat mounting hole 103 by welding, and then it is installed on the tensioning support device.

[0020] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
