LMS-type梅花-shaped elastic coupling

The梅花-shaped elastic coupling consists of two identical half-couplings with claw-shaped protrusions and an elastic element. The梅花-shaped elastic element is positioned between the claws of the two half-couplings, thereby connecting them together.

Detailed introduction

Product Features
The梅花-shaped elastic coupling consists of two identical half-couplings with claw-shaped protrusions and an elastic element. The梅花-shaped elastic element is placed between the claws of the two half-couplings, thereby achieving the connection between them.

It features compensation for relative misalignment between the two shafts, vibration damping, shock absorption, a small radial dimension, a simple structure, no lubrication required, relatively high load-carrying capacity, and easy maintenance.

Application scenarios
Suitable for applications involving the connection of two coaxial shafts, frequent starts and stops, reversible operation, medium-to-low speeds, small-to-medium power transmission systems, and operating environments that demand high reliability.

LMS-type梅花-shaped elastic coupling
The LMS (double-flange type) plum-blossom-shaped elastic coupling allows replacement of the elastic element without axially moving the coupling. Its structural configuration is shown in Figure 6.2, and its technical parameters and main dimensions are listed in Table 6-2.

Diaphragm coupling

The diaphragm coupling is a metallic flexible coupling that can compensate for deviations in the radial, axial, and angular directions. Compared to conventional diaphragm couplings, it features a compact structure, strong corrosion resistance inherent in the diaphragm itself, high load-carrying capacity, light weight, and suitability for high rotational speeds.

T-type and D-type diaphragm couplings

The diaphragm coupling compensates for the relative displacement between the two connected shafts through the elastic deformation of its diaphragm, making it a high-performance, metal-based flexible coupling with strong mechanical properties.

F-type diaphragm coupling

The F-type structure combines the advantages of both the R-type and G-type designs. For the same specification, the F-type has a greater shaft diameter capacity than the R-type and a smaller outer diameter than the G-type.

G-type diaphragm coupling

In addition to the key advantages of R-type couplings, the G-type coupling’s half-coupling features a larger shaft diameter capacity and can be manufactured with either straight bores or tapered bores (for hydraulic assembly and disassembly), or it can be conveniently connected to flanged shaft discs. The G-type is particularly well-suited for large electric motors, generators, or steam turbine units. Among all types of couplings, the G-type coupling is the easiest to assemble and disassemble.

R-type diaphragm coupling

The R-type structure ensures that the center of gravity on both sides is as close as possible to the support bearings of the two units, minimizing additional bending moments at the rotor shaft end and thereby promoting smooth, high-speed operation. The flexible components—comprising the half-coupling, diaphragm assembly, and protective sleeve—have been fully assembled prior to leaving the factory and are connected via a stop collar on the intermediate section, allowing for easy overall assembly and disassembly. Even after multiple reassemblies and disassemblies, this coupling maintains permanent alignment and dynamic balance. The large distance between the two flexible elements (diaphragms) enables the coupling to effectively absorb misalignment between the units. The intermediate section—being sufficiently long—can be removed to facilitate easy disassembly of the half-coupling from the shaft without requiring any movement of the entire unit (the same applies during installation). Shims at both ends of the intermediate section can be added or removed to compensate for installation errors and to conveniently achieve pre-tensioning, thereby accommodating thermal expansion or other dynamic misalignments of the units.

NUP New Elastic Sleeve Pin Coupling

The NUP flexible coupling’s elastomer material is made of polyurethane reinforced with graphite, offering excellent toughness, self-lubrication, and wear resistance. It features a hollow-grid design and comes in three different elasticity options, providing superior vibration absorption and impact resistance. The conical-bore bolts ensure a tight fit that remains secure and does not loosen over time. Thanks to its high safety and reliability, as well as its outstanding vibration absorption and impact resistance, this coupling has received unanimous praise from more than 100 users. As a result, it has been awarded innovation funds by the Ministry of Science and Technology of China, the Provincial Department of Science and Technology, and the Municipal Science and Technology Commission.

NUPEX Combination Flexible Coupling

The NUPEX combination elastomeric coupling is a high-performance coupling developed and launched onto the market in 2000 by Schenck Power specifically for the characteristics of variable-frequency drive units. After successful application at the Jinxi Petrochemical Plant, more than 300 units have been installed to date, all operating smoothly and delivering excellent results.

Compensating capacity for relative displacement between the two shafts of a drum-type gear coupling

1) When there is no radial displacement between the two shaft axes, the permissible radial misalignment △α is as follows: For each pair of meshing internal and external teeth in a gear-type coupling with drum-shaped teeth, the permissible angular misalignment △α is 1°30'.
