Problems solved by technology

The disadvantage of the two friction wheel mine hoists is that the cooling of the motor is not effective
Also in the above solutions there are either relatively large bearing spacings, which are limited by the connection of the cooling air channels between the bearings, or they are bulky or the shaft members are difficult to handle

Embodiment Construction

[0029] figure 1 A friction wheel mine hoist is shown with a friction wheel 2 around which a hoisting wire rope is guided in a friction wheel liner 31 . The cylindrical housing 4 is connected to the motor 5 via a web 32 . The motor 5 is arranged in a cavity 12 which is surrounded by a cylindrical housing 4 and side panels 13 . The cavity 12 is used for forced ventilation of the motor 5 or the rotor 6 and the stator carrier 7 with cooling air which flows into the cavity 12 via the hollow shaft 3 and flows out of the cavity again. The two partial shafts 18 and 19 are connected via connecting flanges 14 and 15 to the supporting wall 8 which is here integral. Here, the bearing wall 8 , the hollow shaft 3 and the stator carrier 7 form a bearing structure 10 . Bores 33 remain, shown here only for feeding cooling air in the direction of cavity 12 . The support wall 8 simultaneously serves as a partition wall 16 . Arrow 51 indicates the flow of cooling air from the hollow shaft 3 ...

Abstract

A friction wheel or drum hoist, which has an electric motor (5) for driving the hoisting wire rope (11), the rotor (6) of the motor is connected to the cylindrical casing (4) of the friction wheel (2) , while the stator bracket (7) of the motor is fixed on a support structure with a hollow shaft (3), the hoist is characterized by improved ventilation. Wherein the motor (5) is arranged in a cavity (12) inside the cylindrical housing (4) between the guard plates (13) of the friction wheel (2), which can be used for forced ventilation of the motor (5) Apply a shot of cooling air. The hollow shaft (3) is formed here by two partial shafts (18, 19), which together with at least one bearing plate (8) and the stator carrier (7) form the bearing structure (10).

Description

technical field [0001] The invention relates to a friction wheel or drum hoist with an electric motor for driving the hoisting rope, the rotor of which motor is connected to the cylindrical housing of the friction wheel, while the stator support of which is fixed to a support structure with a hollow shaft , wherein the motor is arranged within the cylindrical housing between the shields of the friction wheels in a cavity that can be filled with cooling air for forced ventilation of the motor. Background technique [0002] A mine hoist of this type is known, for example, from DE-PS 4222094 or DE-PS 4405593. The former has a hollow shaft with an enlarged diameter in the middle and two oppositely inclined wall sections, through which the cooling air is to be directed essentially radially towards the inside of the friction wheel cover of the cylindrical housing. The latter has a solid one-piece shaft with a fan outer ring for the circulation of cooling air between the shaft and...
