DEUTZ engine flywheel , Iran

The flywheel ring gear of DEUTZ engines is manufactured from medium carbon steel grade CK45. Induction hardening heat treatment raises the tooth surface hardness to 45 to 50 HRC. The tooth module in most series equals 2.5 or 3.0 millimeters. The number of teeth varies between 110 and 135 depending on starter power. The outer diameter of the ring gear in series 1013 is approximately 320 millimeters. Series 912 and 913 have an outer diameter of 280 millimeters. The tooth width (face width) is typically designed between 18 and 22 millimeters. The pressure angle is a standard 20 degrees for optimal starter engagement. The ring gear is mounted on the flywheel with an interference fit of 0.25 to 0.35 millimeters. This press fit requires no key or bolts and is completely non-detachable.

The ring gear withstands the highest torque during engine starting. The torque transmitted from the starter to the teeth ranges between 150 and 300 Newton meters. CK45 steel has a thermal expansion coefficient of 11.5 micrometers per meter-Kelvin. This value differs slightly from the cast iron flywheel coefficient of 10.8. The differential thermal expansion maintains the interference fit at operating temperatures up to 120 degrees Celsius. The tooth profile is typically involute with tip modification. This profile optimizes stress distribution during starter impact. The case hardening depth on tooth surfaces reaches 0.8 to 1.2 millimeters. This hardened layer reduces wear and increases service life. Damaged teeth can be replaced separately without replacing the entire flywheel assembly.You can order and buy DEUTZ engine flywheel from Iran by contacting us through whatsaap and email.
