planetary gearbox for slewing drive

Main Features:                                    

1.Flange installation                              
2.The integrated output pinion shaft                 
3.High strength design                            

4.High load capacity                              
5.Heavy load bearing support extreme load from output shaft               
6.Integrated Design  

YJH 700 series is an integrated motor reducer specially designed for less than 20 T excavator. Its

strong momentum comes from hydraulic piston motor which cooperates with KAYABA. It can be

installed in tight spaces. Choose the standard small gear, or customized according to customers'

specifications. 

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

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

The gearbox design is based on many years of practical application experience. The maximum output torques T_2max indicated under technical data for crane applications relate to FEM Section 1, 3^rd 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 factor K.
