INTRODUCTION Nexen 5HPSP‑E Single Position Tooth Clutches are designed for applications where exact timing to two components is required.. EXAMPLE: The required differential engagement speed using a Model 5H45P-E clutch at 60 psi is 150 RPM. (Clutch rotating at 1250, machine component at 1100). The referred inertia is 3 lb. • ft2. The differential RPM limit for the clutch is: Tooth clutches are normally engaged when stationary.
INSTALLATION Refer to Figure 1. Nexen 5HPSP-E Series clutches have a drive flange with two bearings, a pilot diameter, and tapped holes for mounting a pulley, sprocket, or the Nexen Clutch Coupling (Refer to Sales Brochure L-20208) (See Table 2 for recommended tightening torques). 1. Install Nexen Clutch Coupling , Bearing Supported Pulley, Sprocket, or Gear (Table 2). 2. Insert customer supplied key into shaft.

LUBRICATION NOTE Nexen pneumatically actuated devices require clean, pressure regulated air for maximum performance and life. All seals in Nexen Pneumatically operated devices are lubricated for life and do not require additional lubrication. However, some customers prefer to use an air line lubricator, which injects oil into the pressurized air, forcing an oil mist into the air chamber.
AIR CONNECTIONS The following is a common air supply scheme used with this product. This is an example and not an all-inclusive list. All air circuits to be used with this product must be designed following EN983 guidelines. Although Nexen 5HPSP‑E Enclosed Tooth Clutches are air actuated with a maximum operating air pressure of 80 PSI, use only enough air pressure to deliver ample torque for the application. Operating air pressures over 80 PSI will eventually cause bearing and seal damage.
TROUBLESHOOTING PROBLEM PROBABLE CAUSE SOLUTION Failure to Engage Control Valve malfunction or low air pressure. Check system for air leaks or replace Control Valve. Lack of lubrication on Hub Spline or in Air Chamber Lubricate Hub Spline and check Air Chamber Lubrication. Using rigid pipe or tubing for air line connections. Use flexible pipe or tubing for air line connections. Use of a rigid inline coupling mounted directly to the Drive Flange. Use Nexen's Flexible Clutch Coupling.
