In the composition structure of the disc type coupling, discs of different shapes play their own unique roles, and their characteristics also determine the differences in applicable scenarios, as follows:
Separated Connecting Rod Disc
Each disc is composed of a single thin rod to form a polygon. The shape of the rod is simple and easy to manufacture, but the precision of each hole spacing is required to be high. Its working performance is basically the same as that of the continuous polygonal annular disc, but the strength and the speed it can withstand are lower. It is suitable for occasions where the size of the disc pack coupling is limited, and it can achieve torque transmission and deviation compensation in a limited space.
Spoke Disc
Each lamine coupling is composed of several discs. The screw holes on the outer and inner edges of the disc are respectively connected to the master and slave half couplings, and torsion will occur during operation. The molded holes on the disc are to increase elasticity. Due to the elasticity requirements, the difference between the inner and outer diameters should not be too small. This type of disc is suitable for transmitting small and medium power and is more suitable for medium-load transmission scenarios.
Molded Disc
Each coupling is composed of a single disc, and the thickness of the disc decreases from the inner diameter to the outside according to the hyperbolic law to maintain equal strength conditions. It has high material utilization rate and good integrity, and is particularly suitable for high-speed transmission. However, the manufacturing precision of the disc is high, and it can stably transmit torque under high-speed operation to ensure the accuracy of transmission.
Wave Disc
The disc is wavy in the axial section, with high elasticity and good compensation performance. The disc thickness can be divided into equal thickness and unequal thickness. Among them, the single-piece hyperbolic type has better performance and is currently widely used. It can effectively compensate for the axial, radial and angular deviations of the shaft system, and performs well in occasions with high compensation requirements.
Discs of different shapes meet the needs of membrane couplings in torque transmission, elastic compensation, speed adaptation, etc. through their own structural designs, providing suitable solutions for transmission under different working conditions.
