Hydraulic shrink disc

What is a hydraulic shrink disc?

The hydraulic shrink disc uses hydraulic pressure to create a secure connection between the shaft and hub. First, the disc is pushed onto the hub and then hydraulic oil is introduced into the hydraulic chamber. This causes the two pressure rings to move axially towards each other. The conical surfaces create radial pressure on the hub. This creates a firm, backlash-free and maintenance-free connection between the shaft and hub

Advantages of the hydraulic shrink disc

The use of a hydraulic shrink disc offers numerous advantages:

  1. High transmission forces: It can transmit high torques and forces.
  2. Precise and backlash-free connection: The connection is precisely aligned and free of play.
  3. Simple assembly and disassembly: Assembly is quick and easy without any time-consuming reworking.
  4. Maintenance-free: It requires no regular maintenance after installation.

Applications of the hydraulic shrink disc

Hydraulic shrink discs are used in many areas of mechanical engineering:

  1. Machine tools: In lathes, milling machines and drilling machines.
  2. Drive technology: In gearboxes, pumps and compressors.
  3. Heavy industry: In rolling mills, presses and large machines.
  4. Energy technology: In generators, wind turbines and turbines.

Selection and installation of the hydraulic shrink disc

Selecting the right hydraulic shrink disc depends on the size of the shaft, torque requirements, operating temperature and other specific requirements. Installation usually requires specialized hydraulic components and a thorough understanding of the assembly processes to ensure a safe and effective connection.
