With the high-speed train, subway, expressway and Mining industry and other industries developing, it is, in one way or another, influence our life. The workplace is changed frequently in that the disassemble and install convenient machinery be needed, especially the large and medium-sized portable belt conveyor. As one of the most important parts of the portable belt conveyor, the transmission mechanism can provide the transmission power to it. The design of transmission mechanism for portable belt conveyor has a direct impact on the performance and cost of the conveyor. The design of transmission mechanisn is studied in this article. Portable belt conveyor is mainly used for inclined conveying bulk and practical materials. It has the advantage of large capacity, simple structure, convenient maintenance. The transmission mechanism of the portable belt conveyor is composed of mortor, transmission drum, coupling, reducer.
Motor Selection:
Different type of portable belt conveyor has a different motor type. If the motor is not properly selected, the portable belt conveyor will break down during operation. As a matter of fact, the motor selection of portable belt conveyor is far more than the actual requirements, it is mainly in order to prevent the phenomenon of the crash in the use process. Therefore, we should select the motor depend on the belt width, lifting height, inclined angle, handling capacity, and the character of the material, the water content of the material. Only the choice of the properly power of the motor, in order to avoid the portable belt conveyor’s motor damage, equipment shutdown and other problems. So as to ensure the smooth operation of the entire production line.
Transmission Drum Selection:
The surface of the transmission drum is covered with rubber or ceramic to increase the friction coefficient between the transmission drum and the conveyor belt. If the load of the transmission drum is too heavy, the design and selection of the drum is not reasonable, which is likely to cause the drum shaft breaking accident.
Reducer Selection:
As the equipment between the motor and transmission drum, the reducer device is one of the most important parts of belt conveyor. It not only to meet the requirement of the transmission power, speed ratio, torque, etc. But also has the characteristics of the lightweight, small size, high efficiency, durable and sturdy, easy maintenance and so on.
Coupling Selection:
Due to the large transmission inclination, in order to reduce the impact on the conveyor belt, reducer, motor and its components, so it is necessary to install the coupling between the motor and reducer. The two shafts connected by the machine always rotate together and cannot be separated during operation. Only by stopping the machine and disconnecting the coupling can the two shafts be separated. The use of coupling is mostly standardized, the design of the choice of rigid movable coupling.
The design of transmission mechanism for portable belt conveyor has the advantage of compact and reasonable structure, safety and reliable operation, and satisfactory design. The design of portable belt conveyor overcomes the disadvantage of the traditional belt conveyor. It can greatly reduce the consumption of energy, and reduces the cost of equipment procurement and maintenance, reduce the incidence of failure, and improves the flexibility and production efficiency of the equipment. Achieved the goal of reducing cost and increasing efficiency.
