German CSK 15-P-2RS coupling, CSK 15-P-2RS model, CSK 15-P-2RS price

CSK 15-P-2RS coupling contains an elastic compound with pre-compressed rubber, providing additional strength and extending service life. This coupling accommodates all types of misalignment. The hub material is high-strength aluminum alloy, which is lightweight and corrosion-resistant. The rubber component is primarily used for vibration damping, ensuring smooth and quiet power transmission, thereby protecting the driving force and the driven machinery. Installation is simple; since the rubber part is a split insert, it can be installed by insertion after shaft alignment. The flexible coupling uses a parallel or spiral slot system to accommodate various misalignments and transmit torque precisely. Flexible couplings generally offer good performance and price advantages, making them the preferred choice in many practical applications of stepper and servo systems. The one-piece design enables the flexible coupling to achieve zero-backlash torque transmission and maintenance-free operation. Flexible couplings mainly consist of the following two basic series: spiral slot type and parallel slot type.

CSK 15-P-2RS coupling introduction

Gear couplings have small radial dimensions and high load-carrying capacity. They are commonly used for shaft transmissions under low-speed and heavy-load conditions, such as in metallurgy, mining, and lifting/transport industries, and are also suitable for petroleum, chemical, and general machinery industries. High-precision gear couplings that have undergone dynamic balancing can be used for high-speed transmissions, such as gas turbine shaft transmissions. Since drum-shaped gear couplings offer greater angular compensation than straight-tooth gear couplings, drum-shaped gear couplings are widely adopted both domestically and internationally, while straight-tooth gear couplings should be avoided whenever possible. Gear couplings are a type of movable rigid coupling. They transmit torque and rotational motion between the two halves of the coupling through the meshing of internal and external teeth, suitable for connecting transmission shaft systems of two concentric shafts, and possess certain capability to compensate for relative displacement between the two shafts. Its structure is shown in Figure One, consisting mainly of internal gear rings, gear shaft sleeves, and end covers. Generally, for small-sized gear couplings, the end covers and internal gear rings can form an integrated unit. Due to their compact structure, high load-carrying capacity, wide operating speed range, and reliable operation, gear couplings are widely used in various mechanical industries such as metallurgy, mining, lifting/transport, petroleum, and shipbuilding.

Since drum-shaped gear couplings offer greater angular compensation than straight-tooth gear couplings, drum-shaped gear couplings are widely adopted both domestically and internationally, while straight-tooth gear couplings are considered obsolete products and should be avoided whenever possible. Commonly available gear couplings on the market include standard structural gear couplings, drum-shaped gear couplings, and nylon gear couplings. Among these, drum-shaped gear couplings come in numerous models and are widely applied.

CSK 15-P-2RS coupling maintenance

There are hundreds of varieties of gear couplings, but the basic forms are just two: 1) internal and external gear combination type; 2) end face gear combination type. Other forms are variations based on these two. The internal and external gear combination type gear coupling transmits relatively high torque, taking into account the different needs of users during design, it is intentionally designed so that the lengths of the shaft ends on both sides of the gears are inconsistent, so that users can choose the installation direction according to their needs. Therefore, There is no specification regarding which end faces which direction. If replacing on existing equipment during installation, then generally it should be consistent with the original direction; if it is newly designed and manufactured equipment, then it must be installed under the premise of not interfering with other surrounding parts, following the principle that the more internal and external gear contact surfaces, the more reliable the installation. When inspecting gear couplings, the following methods are generally used: 1) Check the meshing condition of the coupling gear teeth, the contact area along the tooth height shall not be less than 50%, and along the tooth width shall not be less than 70%, the gear surface must not have severe pitting, wear, or cracks. 2) The total radial runout of the coupling external gear ring shall not exceed 0.03mm, and the axial runout shall not exceed 0.02mm. 3) If the gear ring needs to be removed, special tools must be used, do not hammer, To avoid bending or damaging the shaft. During reassembly, heat the gear ring to approximately 200 °C before mounting it onto the shaft. The interference fit between the external gear ring and the shaft is generally 0.01 to 0.03mm. 4) When reinstalling the intermediate sleeve or other components, assemble them according to the original markings and data. 5) Tighten the bolts evenly using a torque wrench.
