Diaphragm coupling characteristics and design applications
幸运飞艇计划格式Diaphragm coupling with high-strength austenitic stainless steel diaphragm, the torque can be twisted in the larger deformation, thus compensating for misalignment between the two axes. Non-metallic elastic coupling by non-metallic elastic components of low-strength and easy to aging constraints, not only short life, but also compensation ability. Tooth coupling by the tooth surface relative slip speed and lubrication conditions constraints (with information, the relative slip of the tooth surface speed should not exceed 0.12 m / s), the angular compensation ability is small. Therefore, non-metallic flexible couplings and gear couplings require a higher installation. Once misaligned out of the scope of the permit, it will cause rapid failure of the coupling.
Dry coupling, no lubrication required
幸运飞艇计划格式All-metal structure, transmission torque capacity, long service life
幸运飞艇计划格式Diaphragm coupling metal diaphragm as a flexible element, high strength, transmission load capacity, and the entire product does not exist non-metallic parts, no aging problems, long life, but also for harsh environments. This is non-metallic elastic couplings unmatched.
Compensation misalignment ability, easy to find installation
幸运飞艇计划格式Diaphragm couplings rely on metal diaphragm to transmit torque and absorb deformation caused by misalignment. There is no relative movement between components and there is no friction / wear, so lubrication is not required, which is in line with the development direction of process equipment without oil. Teeth couplings are rigid, moveable couplings that compensate for misalignment between shafts by the relative slip between the tooth flanks, so the gear coupling must be lubricated, and the lubrication conditions determine the gear coupling The key to good or bad shaft work. Especially in the high-speed operation is more prominent, such as the role of centrifugal force, oil separation, leakage, etc., and the choice of lubricant, often due to lubrication design is connected to the machine bearing lubricant, rather than carrying capacity More suitable gear lubricant. Therefore, high-speed gear coupling lubrication problems are particularly prominent. On the other hand, the wear caused by the relative slip of the tooth surface can cause a series of problems such as sludge and imbalance. So, although the gear coupling was once the best choice for high-speed high-power applications, with the advent and development of the diaphragm coupling, the gear coupling gradually faded out。
