Train Coulper
1. Train Coulper can reduce the vibration of mechanical transmission system.
2. Train Coulper has a strong ability to compensate for two-axis misalignment.
3. Train Coulper has no noise and no lubrication.
- Information
Introduction of Train Coulper:
Train Coulper is used to connect the driving shaft and driven shaft on the train to make them rotate together, and is mainly used for high-speed and heavy-duty power transmission.
Applications of the Train Coulper:
Train Coulper is the key component of high-speed train drive and the driving soul of high-speed train. It can fully meet the high-speed train's high-speed, low-vibration, and low-noise requirements.
Features of the Train Coulper:
1. Train casting can be assembled and disassembled without interfering with the master and slave devices.
2. Train casting has a strong ability to withstand eccentricity and has a corresponding ability to reduce vibration and noise. The misalignment capability can meet the misalignment requirements of most operating transmission equipment.
3. With a high power-to-mass ratio, Train casting is especially suitable for connecting high-power power equipment.
4. Train casting imposes predictable low additional load on connected equipment.
5. Train casting has zero clearance and constant low unbalance.
