Speed increasers are essential components in mechanical transmissions used in hydraulic systems, designed to increase the output rotational speed relative to the input speed. Primarily used to connect the power take-offs (PTOs) of industrial vehicles and agricultural machinery to hydraulic pumps, they convert low rotational speeds into the operating speeds required to ensure proper hydraulic fluid flow rates. These units are commonly installed on earthmoving equipment, forestry vehicles, and truck-mounted hydraulic systems, ensuring continuous power transmission through high-strength gears.
Within the range, solutions vary according to pump size and the operating conditions of the hydraulic circuit. For coupling medium-sized gear pumps, the Borelli Speed Increaser Gr. 3 Series 71000 ensures optimal speed adjustment while minimizing overall dimensions. When higher flow rates are required, the Borelli Speed Increaser Gr. 3.5 Series 80000 is designed to safely transmit higher starting torques. In systems requiring precise coupling solutions, the Borelli Pump Coupling Gr. 2/3 Series 85000 ensures perfect alignment between the drive shaft and the hydraulic pump.
For heavy-duty applications characterized by pressure peaks and prolonged operating cycles, the preferred choice is components with maximum structural rigidity, such as the Borelli Cast Iron Speed Increaser Gr. 2/3 Series 97701, whose cast iron housing provides superior heat dissipation. The entire range stands out for its high wear resistance, precision-ground gear tooth profiles that reduce noise and vibrations, and full dimensional compatibility with commonly used SAE and DIN flanges, facilitating retrofitting and maintenance operations.
