P.T.O. Gear boxes
A transmission gearbox is a central component in many hydraulic and machine applications and enables the targeted adjustment of torque and speed between the drive and output. Depending on the transmission ratio, a transmission gearbox can increase or reduce speeds or amplify torques. This makes it indispensable in agricultural technology, construction and forestry machinery, conveyor systems, energy plants and industrial drive trains. In the LöSi® web shop, you will find high-quality transmission gearboxes in various designs, transmission ratios and performance classes – optimally matched to hydraulic motors and mechanical drives.
What is a Transmission Gearbox?
A transmission gearbox is the mechanical manager for speed and force. It adapts the power of a drive source (e.g., hydraulic motor, PTO shaft, e-motor) exactly to the needs of the driven machine.
There are two basic functions:
- Reduction (i > 1): The speed is reduced, the torque increases massively (e.g., for winches or conveyor belts).
- Step-up (i < 1): The speed is increased (e.g., with PTO gearboxes) to operate fast hydraulic pumps on slow tractors.
Our gearboxes ensure that the motor and load work in the optimal efficiency range.
Advantages of Our Transmission Gearboxes
Why not drive directly? Because direct drives would often require huge, expensive motors. A gearbox makes the system compact and economical.
Technical added value for your system:
- Torque Optimization: Allows the use of smaller, cheaper motors, as the gearbox generates the necessary force through reduction.
- Protection Function: The gearbox absorbs axial and radial forces that would otherwise damage the bearings of the hydraulic motor.
- Efficiency: High-quality gearing and oil bath lubrication ensure efficiencies of often over 95%.
- Flexibility: Different designs (bevel, spur, planetary gearboxes) solve every installation problem.
Typical Areas of Application
Transmission gearboxes are the interface in almost all mobile and stationary applications:
- Agricultural Technology (PTO): Drive of hydraulic pumps on tractors for log splitters or slurry tankers (speed increase).
- Material Handling: Drive of heavy belts and augers (speed reduction for high torque).
- Municipal Technology: Sweeper drives that must rotate slowly and powerfully.
- Industry: Agitators in the chemical or food industry.
Selection Criteria & Technical Data
The wrong ratio leads to the machine running too slowly or the motor stalling.
Define these values before ordering:
- Gear Ratio (i): The ratio of input to output speed (e.g., 1:3.8 for PTOs or 3:1 for reduction).
- Input Power: Does the gearbox withstand the torque (Nm) and the kW power of your drive motor?
- Design: Do you need a Spur Gearbox (offset axes) or a Planetary Gearbox (coaxial axes, compact)?
- Connections: Hollow shaft for PTO, flange for hydraulic motor, or cylindrical shaft?
