Abstract
This utility model discloses an eccentric drive gear used in a vibratory pile hammer, consisting of a drive gear (1) and an eccentricity mass (2), which is characterized in that: the drive gear (1) and the eccentricity mass (2) are integrated. The utility model is an eccentric drive gear used in a vibratory pile hammer which ensures a light and small reduction gearbox of the vibratory pile hammer with high working reliability, compact and simple structure, easy production, and reliable performance.
Description
Technical field
The utility model relates to a kind of machine work device that produces excitation force in the vibrohammer gear-box, particularly a kind of vibrohammer eccentric drive gear of being used in.
Background technique
At present, the eccentric massblock that vibrohammer uses all separates with gear, needs links such as bolt or spline to connect between them, and this has often reduced system reliability of using and the volume that has increased gear-box; Simultaneously, centrifugal moment is by the decision of the weight of eccentric massblock and throw of eccentric, increase eccentric moment, must increase the volume of eccentric mass, thereby make the volume of related device increase, and this makes that the volume of speed reducer of present large-scale vibrating pile monkey is too huge.
The model utility content
Technical problem to be solved in the utility model provides a kind of less vibrohammer eccentric drive gear of functional reliability height, compact structure, weight and volume that can make the vibrohammer speed reducer.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of vibrohammer eccentric drive gear, constitute by eccentric massblock and driving gear, and it is characterized in that: described eccentric massblock and driving gear are an integral body.
As a kind of improvement of the present utility model, on eccentric massblock, be perfused with heavy metal.
As further improvement of the utility model, on gear mass, be provided with a through hole that is used to lift by crane transportation at least.
The utility model is because eccentric massblock and being made of one of driving gear, in eccentric massblock, pour into simultaneously heavy metal, under the situation that guarantees the eccentric mass constancy of volume, increase its eccentric moment, simplify the structure of exciting device in the vibrohammer speed reducer, saved unnecessary link, strengthened the reliability of system, under the prerequisite that produces equal eccentric moment, compare with common unit, its volume dwindles greatly, has optimized the structure of speed reducer.So, the utility model be a kind ofly can make functional reliability height, compact structure, the weight and volume of vibrohammer speed reducer less and simple in structure, easily manufactured, the vibrohammer eccentric drive gear of reliable performance.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an axial view of the present utility model;
Fig. 3 is that the A-A of Fig. 2 is to sectional view.
Embodiment
By Fig. 1, Fig. 2 and Fig. 3 as can be seen, end-grain cutting on a circular metal body goes out driving gear 1, cut out eccentric massblock 2 at the other end, the center of metal body is a transmission axis hole 5, wherein cut out two cylindrical holes on the eccentric massblock 2 and be used to pour into heavy metal 3, be used for cooperating transmitting torque with transmission shaft and pin at two pin-and-holes 6,7 that radially cut out of eccentric massblock 2.Three through holes 4 that are used to lift by crane transportation have been gone out in driving gear 1 one end-grain cutting.
The utility model is because eccentric massblock 2 and driving gear 1 being made of one, in eccentric massblock 2, pour into heavy metal 3 simultaneously, under the situation that guarantees eccentric massblock 2 constancies of volume, increase its eccentric moment, simplify the structure of exciting device in the vibrohammer speed reducer, saved unnecessary link, strengthened the reliability of system, under the prerequisite that produces equal eccentric moment, compare with common unit, its volume dwindles greatly, has optimized the structure of speed reducer.
Claims (3)
1, a kind of vibrohammer eccentric drive gear is made of driving gear (1) and eccentric massblock (2), and it is characterized in that: described driving gear (1) and eccentric massblock (2) are an integral body.
2, a kind of vibrohammer eccentric drive gear according to claim 1 is characterized in that: be perfused with heavy metal (3) on described eccentric massblock (2).
3, a kind of vibrohammer eccentric drive gear according to claim 1 and 2 is characterized in that: be provided with a through hole (4) that is used to lift by crane transportation on described driving gear (1) body at least.
