3 Right Angle Bevel Gear Reducers Selection and Ordering Information Overload Service Factors Load and operating characteristics of both driver and driven units must be considered thoroughly when selecting Browning Bevel Gear Boxes. It is essential that all gear boxes be selected for maximum load conditions to be encountered. Browning Bevel Gear Boxes will safely transmit momentary starting loads as great as % of the mechanical input ratings. First determine the load classification of the driven unit from the table on page B-4. Then from the table below, select an overload service factor for this classification, for duration of service to be involved and for the type of prime mover to be used. Overhung Loads When a gear box is driven by any belt, chain, or gear drive, or when the gear box drives a driven unit through a belt, chain or gear drive, overhung loads must not exceed those shown in the tables on pages B-5 - B-8. se the following formula to calculate the overhung load. OL = Prime over Duration of Service Driven achine Load Classification Electric otor ulti-cylinder Internal Combustion Engine Single Cylinder Internal Combustion Engine 2TK D niform oderate Shock eavy Shock Occasional hour per day Intermittent - 3 hours per day p to 10 hours per day hours per day Occasional hour per day Intermittent - 3 hours per day p to 10 hours per day hours per day Occasional hour per day Intermittent - 3 hours per day p to 10 hours per day hours per day Where: OL = Overhung Load (pounds) T = Actual Shaft Torque (Inch-Pounds) D = P.D. of Sprocket, Sheave, Pulley or Gear K = 1.0 for Chain Drives 1.25 for Gear Drives 1.25 for Gearbelt Drives 1.50 for V-Belt Drives No overhung loads are encountered when the gear box is coupling connected to the driver and/or driven machine. owever, care should be taken in aligning the shafts to avoid pre-loading bearings by misalignment. Selection Example A right angle gear box is needed for a line shaft driving processing machinery which requires 30 inch-pounds torque and will operate about 10 hours per day. This line shaft will be coupling connected at a right angle to an existing line shaft which is driven by an 1 rpm electric motor. Existing line shaft is 1 7/16" diameter and the new line shaft is 1 3/16" diameter. 1. Determine the Load Classification of the driven unit. From page B-4, the load class for a line shaft driving processing machinery is. 2. Determine the Overload Service Factor. From the table on this page, the service factor for a moderate shock () load driven by an electric motor 10 hours per day is Determine the Normal Torque (or the Normal hp). ultiply the required torque by the service factor: 30 x 1.25 =12.5 Normal Torque 4. Select the Gear Box. From page B-6 under the 1 RP column, select a gear box which has a mechanical rating of, or slightly greater, which in this case is 1670 and the gear box is 12SB1-10. Check to see that the thermal rating (1670) exceeds the transmitted load (30). 5. Select the Couplings Required. Note: If a chain drive or the other drive has been specified for either or both input or output shafts, the overhung loads would have to be checked from the formula above and from the table on page B List Components 1, 12SB1-10 Bevel Gear Box B-3
