Spur gear ZCL

straight-toothedhub

MATERIAL Glass-fibre reinforced polyamide-based (PA) technopolymer, grey colour. STANDARD EXECUTIONS - ZCL-0.5: module 0.5, not drilled hub (number of teeth Z ≤ 50) or plain pass-through hole (number of teeth Z ≥ 55). - ZCL-1.0: module 1.0, not drilled hub (number of teeth Z = 10) or plain pass-through hole. - ZCL-1.5: module 1.5, plain pass-through hole. - ZCL-2.0: module 2.0, plain pass-through hole. - ZCL-2.5: module 2.5, plain pass-through hole. - ZCL-3.0: module 3.0, plain pass-through hole. In the execution with the plain pass-through hole, the size d in the tables represents the diameter of the minimum 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. TECHNICAL DATA See: Transmission elements. SPECIAL EXECUTIONS ON REQUEST - Assembly by means of a transversal grub screw. - Hub with hole and keyway in compliance with DIN 6885/1 tolerance P9. - Maximum tolerance on plain pass-through hole: IT 9. 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).
