English to Italian Tech/Engineering Engineering (general)

Come tradurreste "gear adjustment wheel"?
So che "gear wheel" vuol dire "ruota dentata", ma in questo caso non saprei come rendere bene la traduzione.

"As noted above, the first asymmetrical differential 102 includes a gear adjustment wheel 144, having gear teeth 150, which extends from the extension (141 in FIGs. 4, 5A-5B, 7A-7B) that is connected to the first high torque gear 120a. The teeth 150 of the gear adjustment wheel 144 are intermeshed with a braking gear 302 of a gear range selector device 300."




Grazie!
