Abstract

A hoisting machine arrangement includes a rope drum, which has a driven gearwheel; a hoisting motor for driving the rope drum; and a gear between the hoisting motor and the rope drum. The gear has a body and a driving gearwheel, the driving gearwheel of the gear being coupled to the driven gearwheel of the rope drum. The body of the gear has a first drilling, which is arranged for fitting a shaft of the driving gearwheel; and a second drilling, which is parallel to the first drilling and arranged for fitting a shaft of the rope drum or the like. A method is disclosed for preparing a gear of a hoisting machine arrangement of this type.

First claim

The invention claimed is:

1. A hoisting machine arrangement comprising:
a rope drum, which has a driven gearwheel;
a hoisting motor for driving the rope drum; and
a gear between the hoisting motor and the rope drum, the gear having a body and a driving gearwheel, the driving gearwheel of the gear being coupled to the driven gearwheel of the rope drum, wherein the gear body includes:
a first drilling, which is arranged for fitting a shaft of the driving gearwheel; and
a second drilling, which is parallel to the first drilling and arranged for fitting a portion of a shaft of the rope drum,

wherein the driven gearwheel is formed or attached to the rope drum,
wherein the driving gearwheel forms an open transmission in combination with the driven gearwheel, and
wherein the rope drum includes an end part, the end part being directly mounted on two bearings located one after the other on the shaft of the rope drum to align the rope drum and the gear to obtain parallel axial lines of the shaft of the rope drum and the shaft of the driving gearwheel to provide a correct center distance between the shaft of the rope drum and the shaft of the driving gearwheel and a correct tooth contact for the driving gearwheel and the driven gearwheel.

2. The hoisting machine arrangement as claimed in claim 1 , wherein the gear body or a part of the gear body where the first and second drillings are located is a single piece.

3. The hoisting machine arrangement as claimed in claim 1 , wherein the shaft of the driving gearwheel and the portion of the shaft of the rope drum extend to the same side in relation to the gear.

4. The hoisting machine arrangement as claimed in claim 1 , wherein the driven gearwheel is formed or fastened to an inner circumference of the rope drum or to an edge of the rope drum.

5. The hoisting machine arrangement as in claim 1 , wherein a distance between the first and second drillings and their parallel orientation define a centre distance between the driving gearwheel and the rope drum.
