German CSK 35-2RS coupling, CSK 35-2RS model, CSK 35-2RS price

CSK 35-2RS couplings transmit motion by welding or bonding a thin-walled corrugated tube (bellows) directly to the two coupling halves. This type of coupling has a simple structure, compact dimensions, is easy to machine and install, and offers high transmission accuracy. It is mainly used in low-power precision machinery and control mechanisms that require a compact structure and high transmission accuracy. The coupling consists of two hubs and a thin-walled metal tube, connected by welding or bonding. Although many other materials are available, stainless steel and nickel are the most common materials for the metal tube. Nickel tubes are produced by electrodepositing. This method first involves machining a solid mandrel into a corrugated shape, electroplating nickel onto the mandrel, and then chemically dissolving the mandrel to obtain the nickel bellows. This method allows control over the precision of the bellows wall thickness and can achieve thinner walls than bellows made by other methods. These thin-walled bellows give the coupling high sensitivity and rapid response, making it ideal for applications in extremely small and precise instruments.

CSK 35-2RS coupling structure and applications

Universal couplings have various structural types, such as: cross-axis type, ball cage type, ball fork type, cam type, ball pin type, ball hinge type, ball hinge plunger type, three-pin type, triple-fork type, three-ball pin type, hinged rod type, etc.; 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-sized 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. The coupling consists of two halves, each connected to the drive shaft and driven shaft respectively. Generally, prime movers are connected to working machines via couplings.

CSK 35-2RS coupling classification

There are many types of couplings. Based on the relative position of the two connected shafts and the nature of positional changes, they can be classified into: 1) Rigid couplings. Mainly 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. Mainly used where there is misalignment between the two shafts or relative displacement 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 using the mobility in one or several directions provided by the movable connections between the coupling's working parts, such as jaw 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 (referred to as elastic couplings) use the elastic deformation of elastic elements to compensate for misalignment and displacement between the two shafts. The 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, first choose the appropriate type based on operational requirements, then calculate torque and speed based on the shaft diameter, look up the applicable model in relevant manuals, and finally perform necessary calculations for certain key components.

CSK 35-2RS coupling selection

Before selecting a universal coupling, the following prerequisites and conditions must be clarified: 1) Whether there is a transmission device between the prime mover and the universal coupling. If so, what is the transmission ratio? After passing through the intermediate transmission device, how many shafts are output, 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 status of the universal coupling? Horizontal, vertical, or inclined installation. Try to keep the shaft 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) Know the required connection forms at both ends of the universal coupling and specific installation dimensions, and understand if 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, what level of balance quality grade is needed? 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 should be determined. By understanding the above prerequisites, gradually determine the specifications of the universal shaft and finally decide which structural form to select. Structural forms of universal couplings include cross-axis type, ball cage type, ball fork type, cam type, ball pin type, ball hinge type, ball hinge plunger type, three-pin type, triple-fork type, three-ball pin type, hinged rod type, etc. 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-sized based on the magnitude of the transmitted torque. To select a suitable coupling for the prime mover from such a wide variety of universal couplings, a thorough understanding of the aforementioned prerequisites and external influencing factors is essential.
