What is coupling in conveyor belt?

Hydraulic couplings are used to gently accelerate belt drives. Hydraulic couplings limit torque, allow load sharing when starting and dampen torsional vibrations, increasing the productivity and longevity of the transport system. Maximum energy savings are also achieved when using fluid couplings, due to the reduction of current peaks. The belt is usually the most expensive part of a conveyor system.

The couplings protect this investment through a smooth and reliable operation that eliminates mechanical shocks in the drive chain. Benefits and advantages The belt is often the most expensive part of a conveyor system, and couplings must protect that investment through smooth and reliable operation. As mentioned earlier, hydrodynamic couplings, by design, transfer energy with negligible wear and tear and eliminate mechanical shocks in the drive chain. These are some additional advantages over other methods of energy transmission.

GN 2244 bellows transmit angular positions and torques with extreme precision and without clearance. The metal bellows also reliably compensate for shaft misalignments and eccentricity tolerances.

In the material handling industry, an individual conveyor belt is usually just one link in a narrow chain of material handling machinery. Beam couplings are best suited for small, lightweight belt-driven conveyors used in applications such as assembling or loading parts by CNC. In large conveyor systems, the belt is in most cases the most expensive component and therefore determines the investment cost and economy of the entire plant. These larger capacity conveyors are usually designed with reduced safety margins on the belt, requiring greater control of the drive system to ensure maximum availability and reduce any unexpected downtime.

The conveyor belt can only be started after receiving the green light from the system monitoring the general operation (tension, speed, lubrication pressure, etc.) The TV is perfectly adapted to short horizontal conveyors or conveyors with a sharp inclination in a straight line, and is mainly used with low-power belt drives. Design 3 (TVVS coupling) Thanks to its smooth accumulation of torque, this type is also suitable for longer conveyor belts with starting times of up to 50 s. Based on these calculations, the software can generate starting curves that can be used to optimize other belt parameters, such as belt quality and tension settings. With reference to the VDI standards, suitable couplings for conveyor belts can be classified as shown in the figure.

Variable speed and filling-controlled couplings are used on conveyor belts with special requirements related to increased tensile force, torque limitation and operating behavior. The above-mentioned examples can only be considered an extract of the numerous applications of hydrodynamic couplings in conveyor belts for the transport of bulk material. In particular, TurboSim allows engineers to simulate the starting behavior of conveyor belts under various environmental conditions and load scenarios. Voith, for example, offers a wide range of couplings for conveyor belts with power levels from 37 to 4000 kW.

Torque accumulation time is used as the main control variable until the conveyor breaks, while constant acceleration is used as a control variable after the conveyor breaks. Precision conveyors for semiconductors These pallet conveyors usually require high speeds and torque, which are two of the main advantages of using a bellows coupling. .
