Description
Technical Field
[0001] The utility model relates to the technical field of pulleys, in particular to a pulley supporting structure. Background Art
[0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy. Wind power generation is very environmentally friendly and has huge wind energy reserves. Therefore, it is increasingly valued by countries around the world. In the process of wind power generation, a pulley needs to be connected to one end of the blade so that the rotation of the blade drives the pulley to rotate, so that the pulley can be connected to other devices to obtain greater wind energy, which can then be converted into electrical energy.
[0003] The existing pulley is a conventional structure, consisting of a one-way mechanism in the middle and support bearings at both ends. The support bearings can keep the torque transmission needle roller in a relative position on the circumference and prevent it from sliding and tilting at will; however, since there is no other support structure on the surface of the conventional pulley, the pulley may shake during the high-speed rotation of the pulley, which will increase the loss of the pulley under long-term shaking, reduce the strength of the pulley itself, and shorten the service life of the pulley, making it inconvenient to use. In view of this, we have introduced a pulley support structure. Utility Model Content
