Embodiment
[0015] Such as figure 1 As shown, the transmission pulley used on large-scale construction machinery equipment includes a pulley body 1 , and several grooves 6 are arranged on the circumferential surface of the pulley body 1 . Groove 6 is for placing belt.
[0016] The center of the pulley body 1 is provided with a through hole 4 .
[0017] The shape of the through hole 4 is rhombus. By setting the through hole 4 as a rhombic hole, the connection between the pulley body 1 and the power element is more stable during the rotation process, and no slippage will occur.
[0018] The pulley body 1 is provided with several threaded through holes 3 .
[0019] The number of the threaded through holes 3 is three, and they are evenly distributed around the through holes 4 . The fixing degree between the pulley body 1 and other components is increased through the threaded through hole 3 .
[0020] Several cavities 2 are provided on the pulley body 1 , and the cavities 2 have the same ...
