Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and embodiments, and it is to be understood that the described embodiments are only some embodiments, but not all embodiments, and all other embodiments obtained by those skilled in the art without any inventive work are within the scope of the present invention.

The utility model provides a driving sheave mechanism as shown in fig. 1, including the supporting seat, its characterized in that supporting seat 1 divide into about two parts, installs shaft 3 on the supporting seat 1, install a pair of bearing 5 on the shaft 3, bearing 5 installs between shaft 3 and driving sheave 8, bearing end cover 4 is installed in the shaft left side, shaft 3 cooperates fixed mounting on supporting seat 1 through epaxial vertical draw-in groove and cardboard 6.

Further, the wheel shaft 3 is fixed on the supporting seat 1 through a clamping plate 6 and a longitudinal clamping groove in the wheel shaft 3, and the clamping plate 6 and the supporting seat 1 are fixedly installed.

Further, the right side of the bearing 5 is positioned through a thin tooth 7 in the shaft hole of the traction sheave 8 and the shaft shoulder of the wheel shaft 3, and the left side of the bearing 5 is positioned through the bearing end cover 4 and the shaft shoulder of the wheel shaft 3.

Further, the bearing end cover 4 is fixed on the traction sheave 8, and a sealing felt 2 is arranged between the bearing end cover 4 and the wheel shaft 3.

The utility model discloses a theory of operation does: the axle 3, which is fixed by means of the clamping plate 6 and the support 1, is a fixed axle, because in this way the traction sheave 8 is fixed in the axial and radial directions, so that the axle 3 is a fixed axle, which axle 3 supports the traction sheave 8 during operation. A pair of bearings 5 are arranged between the traction sheave 8 and the wheel shaft 3, two sides of the pair of bearings 5 are respectively axially positioned through the bearing end cover 4 and the shaft shoulder, and the thin teeth 7 in the shaft hole of the traction sheave 8 and the shaft shoulder, and the bearings 5 cannot axially move in the working process.
