Detailed Description

The present invention will be described in detail with reference to the accompanying drawings, as shown in fig. 1, a traction sheave which is easily disassembled and assembled. The utility model provides a driving sheave of convenient dismouting, includes pivot 1, its characterized in that, connect fixed mounting through keyway 2 in the pivot 1 and have an axle connecting piece 3, be equipped with first bolt hole 4 on the axle connecting piece 3, axle connecting piece 3 adopts bolted connection mode fixed mounting with driving sheave 5, be equipped with supporting seat 12 on the axle connecting piece 3, supporting seat 12 and 5 in close contact with of driving sheave, through the screw connection fixed mounting has locating plate 13 on the axle connecting piece.

The material of the shaft connecting piece 3 is steel, the material of the traction sheave 5 is nodular cast iron, the wheel groove 6 on the traction sheave 5 is an arc groove, the shaft connecting piece 3 and the rotating shaft 1 are fixedly installed as a whole, the rotating shaft 1 and the shaft connecting piece 3 are connected through the key groove 2, the traction sheave 5 and the shaft connecting piece 3 are connected in a screw mode, the shaft connecting piece 3 and the positioning plate 13 are connected in a screw mode, the traction sheave 5 is supported by the supporting seat 12, and the positioning plate 13 is in close contact with the traction sheave 5 to prevent the traction sheave 5 from axial movement. When the traction sheave 5 has a fault, the traction sheave 5 can be detached and replaced by detaching the screw for connecting the positioning plate 13 and the shaft connecting piece 3 and the screw for connecting the traction sheave 5 and the shaft connecting piece 3.

As shown in fig. 2-3, an end cover 7 is arranged at the upper end of the traction sheave 5, a second bolt hole 8 is arranged on the end surface of the traction sheave 5, a large gear 9 is fixedly mounted on the end surface of the traction sheave 5 through bolt connection, the large gear 9 mounted on the end surface of the traction sheave 5 is in meshing transmission with a small gear inside a manual rescue system 10, and when the traction sheave mechanism fails, the rotation of the traction sheave 5 can be controlled only by manually rotating the manual rescue system 10.
