Operating Principle<\/h3>\n

Speed reducers are used to connect hydraulic motors in self-propelled agricultural machinery, earthmoving equipment and marine applications. The output speed of these reducers is consistently set at 200 rpm. Accordingly, the operating speed of the connected hydraulic motors is adjusted to ensure efficient performance, provided that the input speed never exceeds the maximum limit of 3000 rpm.<\/p>\n

Construction Features<\/h3>\n

The Borelli Group 2 SAE A Cast Iron Speed Reducer – 97500 Series features a housing manufactured from high-strength aluminium and cast iron, designed to withstand demanding operating cycles. The internal gears are carefully designed in full compliance with ISO\/DIN 3990-80 industrial standards and manufactured from high-quality UNI 18NiCrMo5 steel. The gear teeth are precisely corrected and shaved to maximize accuracy and reduce friction. For power transmission, the shafts are manufactured from robust 16CrNi4 steel and securely connected to the gears using dedicated mechanical keys.<\/p>\n

Operating Specifications and Maintenance<\/h3>\n

The torque ratings specified for the speed reducers are optimized for continuous-duty operation. Under intermittent-duty conditions, the nominal torque ratings may be safely exceeded by up to 20%. The component has a rated power of 18 kW and a compact total weight of 10 kg, making installation easier in confined spaces.<\/p>\n

For maintenance, the correct use of SAE 90 oil, with a maximum oil capacity of 0.220 litres, ensures excellent operation and extends the service life of the assembly. The oil level must be visually inspected through the dedicated sight glass every 2000 operating hours. The first oil change is mandatory after the initial 100-150 hours of operation. Finally, to prevent thermal damage, the operating temperature during continuous duty must never exceed 120\u00b0C.<\/p>\n

Hydraulic Motor Coupling and Variants<\/h3>\n

Mounting hydraulic motors onto these speed reducers requires specific connections but offers considerable versatility. Users can connect motors equipped with cylindrical shafts, which require a standard coupling key. Alternatively, motors featuring splined shafts compliant with international DIN or SAE standards can be used; in these cases, power transmission takes place through direct coupling.<\/p>\n
