Applications and Operating Principle<\/h3>\n

The Borelli Group 3.5 Speed Increaser – 80000 Series is used to connect gear pumps directly to the power take-offs of agricultural tractors. Since the standard PTO output speed is 540 rpm, this speed increaser adjusts that speed to the optimal operating speeds required by hydraulic pumps. Different input speeds may be used, provided that the output speed of the speed increaser does not exceed the maximum limit of 3000 rpm. Mounting the hydraulic pump requires a coupling half and a specific adapter flange.<\/p>\n

Construction Features<\/h3>\n

The design prioritizes strength and long-term durability in demanding operating environments. The housings are manufactured from cast aluminium and high-strength cast iron. The core transmission system consists of gears designed in accordance with ISO\/DIN 3990-80 standards and manufactured from UNI 18NiCrMo5 steel. The specially corrected, low-profile gear teeth provide not only greater resistance to mechanical stress but also exceptionally quiet operation. The shafts, manufactured from UNI 16CrNi4 steel, are connected to the gears through robust splined profiles, optimized to withstand the torque ratings specified in the catalogue for continuous-duty operation. Under intermittent-duty conditions, these torque ratings may be exceeded by up to 20%.<\/p>\n

Lubrication Specifications and Operating Temperatures<\/h3>\n

To ensure maximum service life and reliability of the transmission assembly, SAE 90 oil must be used, with a maximum oil capacity of 1.00 litre. Routine maintenance requires visual inspection of the lubricant level through the dedicated sight glass every 1500 operating hours. The first mandatory oil change must be performed after the initial 60 to 80 hours of operation. During continuous operation, the system’s operating temperature must never exceed the maximum limit of 120\u00b0C.<\/p>\n
