KL nylon slider coupling

KL nylon slider coupling is a kind of slider coupling. Its structure is similar to that of the cross slider coupling, except that the middle block is a nylon block.The intermediate sliding block is used to slide in the corresponding radial grooves on the end faces of the coupling halves on both sides to realize the coupling of the two coupling halves.

KL nylon slider coupling is suitable for occasions where the transmission torque is small. It has the performance of compensating the relative offset of the two shafts and buffering. The working temperature is -20℃-70℃, and the allowable speed is 1500-10000r/min. , The transmission torque is 16-5000N.m. Allowable compensation amount: axial △ x=1~2mm, radial △ y ≤ 0.2mm, angular △α≤ 40'.The coupling is noisy, low in efficiency, and wears quickly. Generally, it is not used as much as possible. It is only used when the speed is very low, such as a ball mill.The research and analysis of "KL nylon slider coupling" only focused on the analysis and research of the transmission principle, but did not study the law of motion of each component, the speed, acceleration, inertial force, friction force distribution law and Problems such as energy loss and mechanical efficiency.These problems have a great influence on the transmission performance of the "Old Cross Slider Coupling" in high-power and high-speed transmission, and this is an important theoretical basis in the design of high-power shafts.Using the principles of kinematics and mechanism dynamics, the motion and dynamic characteristics of the "Cross Coupling" are analyzed, and some results in this regard are obtained, and the design and selection of the "Cross Coupling" are provided. The basis.

The KL nylon slider coupling is composed of two half couplings $, L with grooves on the end faces and a middle plate with convex teeth on both sides". Because the convex teeth can slide in the surface groove, it can be compensated. The relative radial and axial displacement between the two shafts during installation and operation. The two halves of the coupling and the intermediate disc form a moving pair, which cannot rotate relative to each other. Therefore, the angular velocity and angular displacement of the main and driven shafts are equal. But when the main and the driven When the axis of the shaft has a radial displacement, the speed and acceleration of each point are different in magnitude and direction, which generates a large inertial force, which increases the dynamic load, friction loss and wear.
