Filed: 1989-02-01
Abstract: PURPOSE:To improve the adhesive strength by inserting a shaft into a magnet, and heating and hardening epoxy resin to make the magnet and the shaft adhere to each other after immersing the magnet in epoxy resin and drying when the shaft adheres to the magnet. CONSTITUTION:Epoxy resin is generally hardened once in a temperature ranging from room temperature to about 80 deg.C, softening with the temperature-rise afterward, and when a temperature reaches 120-150 deg.C, a final hardening reaction occurs. Generally, the first hardening conditions are referred to 'stage B'. After immersing the magnet in epoxy resin, when 'stage B hardening conditions' are attained through a normal temperature drying or at a normal temperature, the magnet is treated under the same conditions as before the immersion. A shaft is inserted into the magnet, and when treated for 1-4 hours at 120-150 deg.C, the resin in stage B conditions in the process of rising temperature is once softened to enter a space between the inside diameter of the magnet and the shaft, and when a temperature rises furthermore, it is hardened at the next step, so that connection between the magnet and the shaft can be made.
