Embodiment Construction

[0017] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0018] Such as figure 1 and figure 2 As shown, the single bearing supporting tensioning winch drum structure of the present invention includes a drum body 5 and a drum shaft 6. The main body of the drum shaft 6 passes through the drum body 5 and is connected by an expansion sleeve 4. One end of the drum body 5 A key sleeve 8 is provided, and the key sleeve 8 is fixedly connected to the drum body 5 through a bolt group 7. The drum structure is also provided with a support frame 9, and a reducer 10 is fixedly installed on the support frame 9 through a flange structure. The reducer The output shaft of 10 is directly connected to the drum body 5 through the key sleeve 8; through this connection, the output shaft of the reducer 10 can directly tran...

Abstract

The invention discloses a roller structure of a tensioning winch supported by a single bearing, which comprises a roller body and a roller shaft. A main body of the roller shaft passes through the roller body and is connected with the roller body through an expansion sleeve; and a spline sleeve is arranged at one end of the roller body and is fixedly connected with the roller body through a bolt group. The roller structure is also provided with a supporting frame; a speed reducer is fixedly installed on the supporting frame, and an output shaft of the speed reducer is directly connected with the roller body through the spline sleeve; one end of the roller shaft is connected with a bearing pedestal through an axial positioning structure; and an end cover is also arranged at the end part of the roller body. The roller structure has the beneficial effects that the defects of larger axial size of the traditional roller structure and the like are overcome, the weight is reduced, the cost is reduced, and the application occasion is also greatly enlarged.

Description

technical field [0001] The invention relates to the technical field of engineering manufacturing, in particular to a single-bearing supporting tensioning winch drum structure. Background technique [0002] The tensioning winch is one of the important components of the belt conveyor, and its performance will directly affect the performance of the belt conveyor. The tensioning winch is mainly to provide sufficient tension for the loose side of the belt conveyor, to prevent the conveyor belt from slipping on the driving roller during start-up or operation, and also to ensure a certain sag between the idler rollers, reducing the Belt running resistance between rollers. [0003] Tensioning winches are mainly divided into heavy hammer type, hydraulic winch type and electric winch type from the structural point of view, especially the winch drum tensioning is the most common. The advantages of winch drum tensioning are large tensioning force, fast tensioning speed, large tensioni...
