A Slotted Disc Spring is used to enable the controlled movement and locking of the planetary gears within the transmission. It is positioned within the rotation housing of the transmission planetary and located between the planetary gear carrier and the rotation housing, securing and controlling the movement of the planetary gears.Attributes:• Prevents unintended movement or slippage with its supporting components• Hardened with Rockwell Hardness Scale value in the range of 42 - 47, indicating its resistance against deformationApplications:A Slotted Disc Spring acts as a locking mechanism for the planetary gears. When torque is applied in the opposite direction, the disc spring expands and engages with the rotation housing, preventing the gears from rotating freely.
