German LEINE LINDE coupling, LEINE LINDE model, LEINE LINDE price

LEINE LINDE couplings utilize their mechanical characteristics to enable continuous rotation of the connected shafts and reliably transmit torque and motion, even when the two shafts are not on the same axis and an angular misalignment exists. The most significant feature of universal couplings is their large angular compensation capability, compact structure, and high transmission efficiency. The angle between the two shaft axes varies with different structural types of universal couplings, generally ranging from 5° to 45°.

LEINE LINDE coupling structure and applications

Universal couplings come in various structural types, such as cross-axis type, ball cage type, ball fork type, block type, ball pin type, ball joint type, ball joint plunger type, three-pin type, triple-yoke type, triple-ball-pin type, and hinge-yoke type; the most common is the cross-axis type, followed by the ball cage type. In practical applications, they are classified into heavy-duty, medium-duty, light-duty, and small-size categories based on the magnitude of the transmitted torque. They are mechanical components used to connect two shafts (drive shaft and driven shaft) in different mechanisms, causing them to rotate together to transmit torque. In high-speed, heavy-load power transmission, some couplings also provide buffering, vibration damping, and improved dynamic performance of the shaft system. A coupling consists of two halves, each connected to the drive shaft and the driven shaft respectively. Prime movers are generally connected to working machines via couplings.

LEINE LINDE coupling classification

Couplings are diverse and can be classified according to the relative position of the two connected shafts and the nature of positional changes as follows: 1) Rigid couplings. Primarily used where strict alignment of the two shafts is required and no relative displacement occurs during operation. The structure is generally simple, easy to manufacture, and ensures identical instantaneous rotational speeds for both shafts. Main types include flange couplings, sleeve couplings, and clamp-shell couplings. 2) Flexible couplings. Primarily used where shaft misalignment exists or relative displacement occurs during operation. Based on the method of compensating for displacement, they are further divided into rigid flexible couplings and elastic flexible couplings. Rigid flexible couplings compensate for displacement by utilizing the mobility in one or several directions provided by the movable connections between the coupling's working parts, such as claw couplings (allowing axial displacement), cross-groove couplings (used to connect two shafts with small parallel or angular displacement), universal couplings (used where there is a large misalignment angle or significant angular displacement during operation), gear couplings (allowing combined displacement), and chain couplings (allowing radial displacement). Elastic flexible couplings (abbreviated as elastic couplings) use the elastic deformation of elastic elements to compensate for shaft misalignment and displacement; these elastic elements also provide buffering and vibration damping properties. Examples include serpentine spring couplings, radial multi-leaf spring couplings, elastic ring pin couplings, nylon pin couplings, and rubber sleeve couplings. Some couplings have been standardized. When selecting a coupling, first determine the suitable type based on operational requirements, then calculate torque and speed based on the shaft diameter, identify the applicable model from relevant manuals, and finally perform necessary calculations for certain critical components.

LEINE LINDE coupling selection

Before selecting a universal coupling, the following prerequisites and conditions must be clearly defined: 1) Whether there is a transmission device between the prime mover and the universal coupling. If yes, what is the transmission ratio? How many output shafts are there after the intermediate transmission device, i.e., is there power splitting? Consider the type, power, and speed of the prime mover. 2) Consider the type of prime mover and the load category for selecting a cross-axis universal coupling to transmit the load: unidirectional constant load, pulsating load, or bidirectional alternating load. What is the installation orientation of the universal coupling? Horizontal, vertical, or inclined? Try to keep the shaft break angle less than 3 degrees. If inclined installation is unavoidable, determine the horizontal and vertical angles. 3) Consider the working environment of the prime mover. Are there adverse environmental conditions such as high temperature, dust, water spray, or chemical corrosion? Select the corresponding type of universal coupling based on the usage environment. 4) Determine the required connection forms at both ends of the universal coupling and specific installation dimensions, and ascertain whether there are special requirements such as mounting brackets. 5) What is the rotational speed of the cross-axis universal coupling itself? Is dynamic balancing required? If dynamic balancing or balancing is required, specify the required balance quality grade. 6) Are there limitations on the installation position? What is the specific installation length? Is telescopic movement required? If telescopic movement is required, what is the outward extension length from the shortest state of the universal coupling? For universal couplings that do not require telescopic movement, compensation for axial dimensional errors must be considered, and the location for compensation within the system must be determined. By understanding the above prerequisites, gradually determine the specifications of the universal shaft and finally decide on the structural type. Structural types of universal couplings include cross-axis type, ball cage type, ball fork type, block type, ball pin type, ball joint type, ball joint plunger type, three-pin type, triple-yoke type, triple-ball-pin type, and hinge-yoke type. The most common is the cross-axis type, followed by the ball cage type. In practical applications, they are classified into heavy-duty, medium-duty, light-duty, and small-size categories based on the magnitude of the transmitted torque. To select a coupling suitable for the prime mover from the wide variety of universal couplings, a thorough understanding of the aforementioned prerequisites and external influencing factors is essential.
