Description

Technical Field

[0001] The invention relates to a reducer structure, belongs to the field of engineering machinery, and in particular to a one-to-two rotary reducer structure. Background Art

[0002] The slewing mechanism is widely used in cranes, hoists, wind power fields and some rotating platforms with special needs in various fields. In the fields of heavy cranes or cranes, multiple planetary gear reduction mechanisms are usually used to drive a slewing mechanism. When multiple planetary gear reduction mechanisms are used to drive the ring gear, the synchronization is poor and the electronic control system is complicated because the reducers are driven separately, and different installation interfaces and adjustments will cause different phases and uneven loads. At the same time, multiple planetary gear reduction mechanisms also need to be evenly distributed in various directions of the ring gear, resulting in more space occupation, and due to the lifting eccentricity of the crane, the loads of multiple planetary gear reduction mechanisms are more uneven. Therefore, it is necessary to design a reducer structure to solve the shortcomings of the prior art, such as poor real-time synchronization of output power between multiple reducers, uneven load, poor load-bearing capacity, and complex electronic control system, so as to ensure real-time and synchronous output power, make the load uniform, improve the load-bearing capacity, and reduce the complexity of the prime mover system control.

On the one hand, the present invention improves the working stability of the rotary mechanism, and on the other hand, only one set of power source input device is required, which greatly reduces the production and manufacturing cost, but it still has the following defects: This design cannot guarantee real-time and synchronous output power, resulting in poor load uniformity and poor carrying capacity.
