Description

Each diaphragm group is made up of multiple pieces stacked together and is divided into connecting rod type and integral type structures. Its core features include: ‌ high torque transmission capacity ‌ (suitable for heavy-load working conditions), ‌ excellent dynamic balance performance ‌ (rotational speed up to over 10,000rpm), ‌ large eccentricity compensation range ‌ (angular displacement up to ±1.5°), and it also has the characteristics of ‌ no lubrication, zero wear, and low noise ‌, with a transmission efficiency as high as 99.86%. It is particularly suitable for high-speed precision transmission (such as servo systems) and corrosive environments (chemical industry, shipping, etc.). Typical applications include shaft transmission of equipment such as water pumps, fans, and compressors. ‌


Product Features


1.High torque transmission capacity ‌
It adopts a seamless connection design of stainless steel diaphragm groups and expansion sleeves, which can withstand heavy-load working conditions and has a transmission efficiency as high as 99.86%. It is particularly suitable for high-power power units ‌.


2.Outstanding dynamic balance performance ‌
The rotational speed can reach over 10,000rpm, the initial dynamic balance accuracy remains stable, and there is no operating noise. It is suitable for high-speed precision transmission (such as servo systems) ‌.


3.Strong deviation compensation capability
The angular displacement compensation reaches ±1.5°, the radial displacement reaction force is small, and it can simultaneously compensate for axial, radial and angular deviations, adapting to complex installation conditions


4.Maintenance-free design
No lubrication requirement, zero wear, long service life, fault status can be checked with the naked eye when the machine stops, low maintenance cost


5.Environmental adaptability
The operating temperature range is from -80℃ to +300℃. It is resistant to acid, alkali and salt spray corrosion and can be applied in harsh environments such as chemical industry and shipping
