Unique Features of Planetary Gearbox

1. High-duty planetary gearbox of modular construction
2. Brand high-performance tapered roller bearing absorbing the forces exerted by the swing gear
3. Built-in multi-chip friction brake
4. Low-noise running, long service life, high efficiency
 

Application Conditions:

The gearboxes have been designed for use at ambient temperatures ranging between -20°Ê and + 40°Ê. Environmental influences such as salt water, salty air, sand, dust, overpressure, heavy vibrations, extreme shocks and ambient temperature, aggressive media, and the like impede the product’s function. To enable a safe design of the winch drive, such conditions must be reported to the factory.
 

Gearbox Design:

The gearbox design is based on many years of practical application experience. The maximum output torques T2max indicated under technical data for crane applications relate to FEM Section 1, 3rd Edition and Section IX (FEM — Federation Europeenne de la Manutention), as well as DIN 15020, collective load class L2, service time category T5 corresponding to driver group M5.
The reference output speed is 25 revolutions per minute maximum. If the swing drive is classified in another driver group, the required output torque must be converted by applying a factor.

Machining Process

Step1. housing processing process: marking → milling the bottom surface to ensure the center height → rough and fine tedious each hole → drilling → inspection and warehousing

Step2. Gear processing process: blanking → rough turning → normalizing → fine turning → gear hobbing → keyway → carburization and quenching → plane grinding → inner hole grinding → gear grinding → inspection and warehousing

Step3. Shaft processing process: blanking → rough turning → tempering → fine turning → keyway insertion → cylindrical grinding → inspection and warehousing

Step4. Inspection equipment: CMM, measuring machine, hole processing accuracy, geometric tolerance, coarseness level 6 remarks:

Each reducer produced by our company is processed through the above process, and the quality is guaranteed
