Advancing Chain technology231 Roller Drive Chain SelectionTechnical Information29 Required Information for Drive Selection :1. Type of input power (electric motor, internal combustionengine, etc.).2. Type of equipment to be Horsepower (HP) to be Full load speed of the fastest running shaft (RPM).5. Desired speed of the slow-running : If thespeeds are variable, determine the horsepower to betransmitted at each Diameters of the driver and driven Center distance of the : If this distance is adjustable, determine theamount of Position of Drive and space limitations (if any).9. Conditions of the Drive . Drives with more than twosprockets, idlers, or unusual conditions such as severelyabrasive or corrosive environments, severely high or lowtemperatures, widely fluctuating loads, frequent startsand stops, etc., require special attention. It is advisableto consult with Renold Jeffrey Engineering personnel inthese :NNumber of teeth on large sprocketnNumber of teeth on small sprocketRRPM of large sprocketrRPM of small sprocketCShaft center distance in Chain pitchesHPHorsepower of Drive motorStep 1: Determine the Class of Driven the Application Classifications chart on page 233,determine the class of driven load to be uniform, moderate,or heavy 2: Determine the Service Table 1, determine the service factor for theapplicatio
Step 8: Check the Final Design. Use the checklist found on page 235 (Table 4) to assure the best balance of drive life, performance, and cost. Step 9: Calculate the Chain Length. Chain Length in Pitches = [(N + n)/2] + (2C) + (K/C) To determine “K”, subtract the number of teeth on the small sprocket from the number of teeth on the large ...
