37 ® HMTP Selection and Ordering Information Example No. 2 Units 107 - 315 Hydraulic Screw Conveyor A hydraulic shaft mount reducer is required to convey dry cement powder. The conveyor will be uniformly fed and operated 12 to 16 hours per day. The screw is 14" diameter and has a 2 7/16" bore with two holes. The conveyor requires 4 ½ HP and will operate at 60 RPM. The application requires a waste pack. 1. Determine the Load Classification From the AGMA Application Classification Numbers section, note the AGMA Class Number is II for a uniformly loaded or fed screw conveyor, operating over 10 hours per day. 2. Determine the Speed Reducer Required From the Hydraulic Reducer Selection Chart section, there are four tables for selecting hydraulic shaft mounts for Class II Service. Locate the 60 RPM row, if available, in each table. Read across the row to find a column with a rating of 4 ½ HP or greater. Read up the column to determine the basic reducer size that corresponds to the design HP. For this application, a 115HMTP15 9T SAE-A 2, 115HMTP25 9T SAE-A 2, 203HMTP25 6B SAEA 2 or a 203HMTP05 6B SAE-A 2 may be used. Generally, the smaller case size is more economical, but the total system should be considered. Select the reducer based upon hydraulic motor characteristics such as spline dimensions and flow rates. (NOTE: Hydraulic motors are not included with the reducer.) For this example, select a 115HMTP15 9T SAE-A 2. 3. Establish Sealing Required for Screw Conveyor The waste pack cartridge is well suited for dry, abrasive materials such as cement powder. Specify the optional waste pack cartridge for the 115 shaft mount selected. From the Accessories section, select part 115-203WPP. 4. Select the Screw Conveyor Adapter and Screw Conveyor Shaft Using the basic reducer size, required drive shaft and screw diameter for the selection; refer to Screw Conveyor Drives in the Accessories section. Note the specification was for a 2 7/16" drive shaft with a two hole arrangement for the 14" diameter screw. From the table select the 115SCA-P and the 115DSP207. 5. Select the Trough End From the Screw Conveyor Trough Ends Sizes 107-407 table, select the SCTE14 X 2 7/16 trough end. 6. List of Components: 1, 115HMTP15 9T SAE-A 2 reducer 1, 115SCA-P screw conveyor adapter 1, 115DSP207 screw conveyor drive shaft kit 1, 115-203WPP waste pack cartridge 1, SCTE14X2 7/16 trough end 1, hydraulic motor (separate) Note: See “Application Considerations” on back cover.
