The locking plates, skillfully embedded in the pin grooves and firmly affixed to the flywheel or machine body with screws, expertly prevent any axial movement of the pins.


IV. Working Principle
(I) Clutching Process
When external compressed air enters the clutch cylinder through the intake hole, it propels the piston into motion. This action, transmitted through the friction pads, clutch body, and flat key, rotates the driven part, achieving seamless clutch engagement and enabling flawless power transmission.

(II) Braking Process
Upon halting the air supply, the piston strategically moves in the reverse direction, guided by the spring. Through the friction pads, clutch body, and flat key, the driven part is swiftly braked. With an astonishing braking time of merely 0.01 - 0.02 seconds, the equipment ensures rapid stopping capability.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
Precision is key—the hole tolerance for installing the four pins must adhere to H7 standards, and the hole center should align parallel to the main shaft center, ensuring unparalleled installation accuracy and stability of the pins.

(II) Geometric Tolerance and Roughness Requirements
Adherence to national standards is non-negotiable for the geometric tolerance and roughness of the center hole and keyway. Similarly, the customer's main shaft must meet these stringent requirements to elevate product performance to its zenith.

(III) Installation Sequence Suggestions
Customers enjoy flexibility in determining the installation sequence. Typically, it is advisable to first install the clutch and brake ear plates, pins, and locking plates, followed by the clutch brake body, for optimal setup.

(IV) Installation Notes for Square Pins
Square pins are invaluable for eliminating installation size discrepancies between two pins and counteracting the thermal deformation of the plate caused by clutch heating. It is crucial to ensure that the two flat surfaces of the square pin remain parallel to the radial direction of the ear plate.

(V) Sealing Requirements for Axial Air Intake
For axial air intake systems, it is imperative to install sealing caps at both ends of the clutch to prevent any potential gas leakage, thereby maintaining system integrity.

(VI) Check after Installation
Post-installation, ensure that both the clutch end and brake end can move freely. This is vital for the smooth and normal operation of the clutch and brake systems, securing uncompromised performance.
