Description

Hydraulic excavating owner Qu Gaoxiao rotary motive power assembly
Technical field
The utility model relates to excavator device, specifically a kind of hydraulic excavating owner Qu Gaoxiao rotary motive power assembly.
Background technique
At present, on market, common digger revolving power assembly reduction speed ratio is conventionally between 18~22, and the rotary motive power assembly starting torque of this reduction speed ratio is little.The actual conditions of excavator, as the side of getting rid of, entrucking are moved required angle of revolution comparatively common 90,120,180, it is long that the time that reduction speed ratio starts and stop during in these angles at the excavator of the rotary motive power assembly between 18~22 is installed, and causes efficiency of excavator low.So research and development one effectively high efficiency rotary motive power assembly seems particularly important.
Summary of the invention
The purpose of this utility model is to provide a kind of hydraulic excavating owner Qu Gaoxiao rotary motive power assembly, can effectively strengthen the velocity ratio of rotary motive power assembly, increases power output torque value, improves the revolution efficiency of excavator.
The purpose of this utility model can realize by following technical solution:
This hydraulic excavating owner Qu Gaoxiao rotary motive power assembly is mainly made up of output shaft, secondary solar gear, secondary planet wheel, one-level sun gear, one-level planet wheel, described secondary solar gear and one-level sun gear are connected to the axle head of output shaft in turn, described secondary planet wheel is engaged on secondary solar gear outside, one-level planet wheel is engaged on one-level sun gear outside, all engagement gear rings separately of described secondary planet wheel and one-level planet wheel outside, the number of teeth of the output gear of described output shaft becomes 11 teeth.
The purpose of this utility model also can realize by following technical solution:
Further, described in this hydraulic excavating owner Qu Gaoxiao rotary motive power assembly, the number of teeth of the gear of secondary solar gear becomes 13 teeth.
Further, the number of teeth of the gear of the wheel of the secondary planet described in this hydraulic excavating owner Qu Gaoxiao rotary motive power assembly becomes 19 teeth.
Further, described in this hydraulic excavating owner Qu Gaoxiao rotary motive power assembly, the number of teeth of the gear of one-level sun gear becomes 13 teeth.
Further, described in this hydraulic excavating owner Qu Gaoxiao rotary motive power assembly, the number of teeth of the gear of one-level planet wheel becomes 19 teeth.
Compared to prior art, the utlity model has following beneficial effect:
The utility model, in the situation that not changing rotary motive power assembly integral structure, adjusts to 25 by reduction speed ratio, has increased the velocity ratio of rotary motive power assembly, has increased power output torque value.
Brief description of the drawings
Fig. 1 is the schematic diagram of a kind of hydraulic excavating owner Qu Gaoxiao rotary motive power assembly of the present utility model.
In figure: 1, output shaft; 2, secondary solar gear; 3, secondary planet wheel; 4, one-level sun gear; 5, one-level planet wheel.
Embodiment
Relevant detailed description of the present utility model and technology contents, coordinate brief description of the drawings as follows, but accompanying drawing only provides the use of reference with explanation, is not used for the utility model to be limited.
With reference to accompanying drawing 1, this hydraulic excavating owner Qu Gaoxiao rotary motive power assembly is mainly made up of output shaft 1, secondary solar gear 2, secondary planet wheel 3, one-level sun gear 4, one-level planet wheel 5, described secondary solar gear and one-level sun gear are connected to the axle head of output shaft in turn, described secondary planet wheel is engaged on secondary solar gear outside, one-level planet wheel is engaged on one-level sun gear outside, all engagement gear rings separately of described secondary planet wheel and one-level planet wheel outside, the number of teeth of the output gear of described output shaft 1 becomes 11 teeth.The number of teeth of the gear of described secondary solar gear 2 becomes 13 teeth.The number of teeth of the gear of described secondary planet wheel 3 becomes 19 teeth.The number of teeth of the gear of described one-level sun gear 4 becomes 13 teeth.The number of teeth of the gear of described one-level planet wheel 5 becomes 19 teeth.
According to formula: i=(Z5/Z1+1) × (Z5/Z3+1)
Improve driving front ratio: i=(Z5/Z1+1) × (Z5/Z3+1)=(52/14+1) × (52/16+1)=20.04.
Velocity ratio: i=(Z5/Z1+1) × (Z5/Z3+1)=(52/13+1) × (52/13+1)=25 after improving.
In the situation that not changing rotary motive power assembly integral structure, reduction speed ratio is adjusted to 25, increase the velocity ratio of rotary motive power assembly, increase power output torque value.
The foregoing is only preferred embodiment of the present utility model, non-in order to limit the scope of the claims of the present utility model, other use the equivalence of patent spirit of the present utility model to change, and all should all belong to the scope of the claims of the present utility model.
