Winding drum speed reduction all-in-one machine

Abstract

The invention discloses a winding drum speed reduction all-in-one machine. The winding drum speed reduction all-in-one machine comprises a sun gear, a duplex planetary gear, a first gear ring, a second gear ring, an outer drum and a gear cover; the sun gear, the duplex planetary gear, the first gear ring and the second gear ring form a planetary gear train; the duplex planetary gear is engaged with the first gear ring and the second gear ring; the first gear ring serves as a fixed end; the planetary gear train is installed in the outer drum; the gear cover fixedly covers the left end of the outer drum; and the second gear ring serves as an output end and is in transmission fit with the gear cover. According to the winding drum speed reduction all-in-one machine, a speed reduction device is integrated in a winding drum, the structural compactness of the whole winding drum is improved, the size of the whole winding drum is reduced, and then the occupied space of winding drum arrangement is reduced; and through the arrangement structure of the duplex planetary gear and the double gear rings, a large transmission ratio is achieved through few parts in the limited layout space, and the load capacity of the winding drum is improved.

Description

technical field [0001] The invention relates to the technical field of hoisting, in particular to a reel deceleration integrated machine. Background technique [0002] As an important output part in the lifting field, the reel is usually used in conjunction with a reducer to achieve a larger output torque, while the existing reel is usually used in conjunction with the purchased finished reducer, and the output end of the lifting reducer passes through The coupling is driven and matched with the input end of the reel, and this structure makes the entire reel structure occupy a large space, which is not conducive to space layout. Contents of the invention [0003] In view of this, the present invention provides a reel deceleration integrated machine, in which the deceleration device is integrated inside the reel, which improves the structural compactness of the entire reel, reduces the volume of the entire reel, and further reduces the occupied space of the reel arrangement...
