Spur Gears Technopolymer, pressure angle 20° MATERIAL Glass-fibre reinforced polyamide-based (PA) technopolymer, grey colour. STANDARD EXECUTIONS - ZCL-0.5: module 0.5, non-drilled hub (for number of teeth Z ≤ 50) or pre-drilled pass-through hole (for number of teeth Z ≥ 55). - ZCL-1.0: module 1.0, non-drilled hub (for number of teeth Z = 10) or pre-drilled pass-through hole. - ZCL-1.5: module 1.5, pre-drilled pass-through hole - ZCL-2.0: module 2.0, pre-drilled pass-through hole - ZCL-2.5: module 2.5, pre-drilled pass-through hole. - ZCL-3.0: module 3.0, pre-drilled pass-through hole. - ZCL-1.0-K: module 1.0, drilled hub with keyway UNI 6604 (see page A-16), D10 tolerance. - ZCL-1.5-K: module 1.5, drilled hub with keyway UNI 6604 (see page A-16), D10 tolerance. - ZCL-2.0-K: module 2.0, drilled hub with keyway UNI 6604 (see page A-16), D10 tolerance. - ZCL-2.5-K: module 2.5, drilled hub with keyway UNI 6604 (see page A-16), D10 tolerance. - ZCL-3.0-K: module 3.0, drilled hub with keyway UNI 6604 (see page A-16), D10 tolerance. For operations with the pre-drilled pass-through hole, in the table the size "d" of the hole represents the minimum diameter of the hole that can be obtained through machining. FEATURES The torques indicated in the tables are granted with rpm included between 0 and 150. Torque values can vary depending on lubrication, temperature, pairing with different materials and continuous operating hours. Maximum tolerance on plain pass-through hole: IT 9. TECHNICAL DATA See: Transmission elements (on page -). SPECIAL EXECUTIONS ON REQUEST - Assembly by means of a transversal grub screw. - Various non-standard gears with hub with keyway according to UNI 6604 tolerance D10. MOUNTING To pair two spur gears, a positive backlash must be considered. For modules 0.5 - 1.0 - 1.5 is recommended the tolerance (+0.03 +0.1). For modules 2.0 - 2.5 - 3.0 is recommended the tolerance (+0.08 +0.3). Standard machine parts Models all rights reserved in accordance with the law.
