Abstract:

Purpose. To estimate the effectiveness of the coupling with rubber-cord shells for evenly distributed load between the transmission lines in the twin-motor drives of tumbling mills.

Methodology. We gave the dynamic and static elastic characteristics of clutches and drive containing the coupling with rubber-cord shells. The performance of couplings containing rubber-cord shell was analyzed based on the mathematical models describing the load transmission lines of each engine depending on the displacement angle of the motor and hydraulic couplings parameters.

Findings. The schemes and characteristics of clutches containing rubber-cord shell are presented. It was proved that these couplings, in case of use of the rubber-cord shells available at the market, allow transmitting the torque of up to 8,000 kN ∙ m, which satisfies the twin-engine drives with a total capacity up to 10,000 kW.

We considered the drives containing the coupling with rubber-cord shells filled with a liquid and connected with hydropneumatic accumulator for the cases when the hydraulic system of rubber-cord shells is independent and connected by the common pipeline. The technique of quantitative evaluation of the uneven distribution of load between the engines was developed.

Originality. The regularities of distribution of static loads in synchronous twin-drum drive mills containing elastic couplings with rubber-cord shells

Practical value. It was proved that the use of flexible couplings with rubber-cord shells without hydraulic connection between the couplings results in a more even load distribution due to the increased compliance of the mechanical system.
