Mining excavator "reassurance" | Sany transmission GS27D2 rotary reducer

The rotary reducer of the excavator is the core transmission component that realizes the positive and negative rotation of the excavator top at the required speed and completes the specified action. It mainly uses the speed conversion of the gear to decelerate the rotary speed of the hydraulic motor to the rotary speed required by the top and obtain a larger torque mechanism.

The Sany transmission GS27D25 rotary reducer is primarily designed for use with the Sany SY485, SY550, and other large tonnage mining excavators. With technological support from the SY485 and SY550 models, the rotary capacity and driving force have been improved by more than 12%. The stability of operation on slopes and performance in various complex conditions has been significantly enhanced. The starting speed of rotation and working efficiency are excellent. As a result, this type of large mining excavator equipped with the "GS27D25" rotary reducer has become an industry favorite, earning reputations such as "new darling" and "red", as well as being recognized for its strong performance in hardcore mining operations.

Advantages of GS27D25 series:

1) Incorporation of enhanced non-standard main bearings in the high load bearing design significantly improves service life;

2) The modular design allows for easy interchangeability with mainstream market configurations after reinforcement, facilitating convenient disassembly and maintenance. It can also be customized to meet customer requirements and is suitable for well-known domestic and foreign brand motors;

3) High-strength steel gears undergo special heat treatment to ensure extended service life;

4) Suitable for use in large excavation, super excavation rotation, and 90-125 ton excavators.
