All gears shall be case ambient and meets USDA class H-2 standards. carburized to insure a high surface durability and resilient tooth core for greater impact resistance and longer service life. C-face reducers shall be of the cross split hollow bore and clamp collar design so as to eliminate backlash at the motor connection, and eliminate, or minimize, fretting corrosion between the motor shaft and the reducer stub shaft.

6 Specification combogear . HOW TO ORDER. APG Reducers and Gearmotors have part numbers assigned that can be found on the selection pages. Refer to the part number when ordering. Always specify mounting position if other than standard, and specify flange mounting and accessories/ modifications, if required. Refer to the following procedure for selection assistance. How To Order 2. Step 1: For applications with one start/hr. or less and nonpulsating ( Motor Load RPM. ). moto drive . Rotating Driven Inertia = Load Inertia x load (starting factor = ) skip Steps 2 and 3 and proceed to Step 4. RPM. For applications with more than one start/hr. proceed to Step 2. 2. Step 2: Determine inertia ratio. Linear Driven Inertia = W x ( __V__. N ). Inertia Ratio = Driven Inertia Where: W = Weight (Lbs.). Driving Inertia V = Linear Velocity ( ). N = Motor RPM.

7 Where: Driving Inertia is defined as the motor inertia. This value must be provided by the motor manufacturer. On APG Gearmotors, If these values are unobtainable proceed to Step 3. driving inertia data is available from your Master Sales Engineer or Application Engineering. ultima . NOTE: Gearbox Inertias, not addressed above, are typically negligible. Driven Inertia is defined as the load inertia referred to the motor If required, inertia values for the APG unit may be obtained speed. The load inertia must be provided by the driven machine from your Master Sales Engineer or Application Engineering. manufacturer. For assistance contact application engineering or see the following formulas. PULLEYS. APG-4. HOW TO ORDER. APG. APG. Step 3: With inertia ratio determined, use Chart 1 to select starting Gearmotor Selection - factor. Chart 1: Starting Factors Determine class of service from Chart 3.

Reducer Selection - Step 4: Determine Driven Machine Factor from Chart 2 below. From rating tables pages D1-7 through D1-48, make reducer selection Master combogear . Chart 2: Driven Machine Factor based on input RPM, ratio, and equivalent HP.

This will indicate Intermittent 2 hrs.

Motor 10-24 hours Multi-cylinder Step 8: Check overhung loads by using the following formula: Internal Intermittent 2 hrs. Combustion Up to 10 hours OHL = 126,000 x HP x Fc x Lf Engine 10-24 hours PD x RPM. moto drive . Single Cylinder Internal Intermittent 2 hrs. Where: OHL = Overhung Load (lbs.). Combustion Up to 10 hours HP = Demand Horsepower Engine 10-24 hours Fc = Load Connection Factor Step 5: Determine service factor. Chain drive : Fc = Synchronous Belt drive Fc = Service Factor = Starting Factor x Driven Machine Factor Spur or Helical Gear Fc = Step 6: V-Belt drive Fc = Flat Belt drive Fc = Reducer Selection- Lf = Load Location Factor. For Lf of low ultima . Using the service factor obtained in Step 5, calculate the equivalent HP speed shaft see page D1-85.

10 By multiplying the demand HP to be transmitted by the service factor. PD = Pitch Diameter (inches). RPM = Revolutions per Minute (output). Equivalent HP = Demand HP x Service Factor Nominal Efficiency To minimize overhung load and increase bearing life, load centerline should be located as close to the shaft shoulder as possible. For Where: Single Reduction Nominal Eff. = applications where OHL exceeds catalogued values contact Application Double Reduction Nominal Eff. = Engineering or use the reducer selection tables to select the next largest Triple Reduction Nominal Eff. = size gearcase.
