Abstract
The utility model discloses a gear for a vibratory hammer. According to the key point of the technical scheme, the gear comprises a gear body, wherein gear teeth, a mounting hole and eccentric holes are formed in the gear body; and the centers of the eccentric holes are separated from the axis of the gear body and the center of the mounting hole. Through holes are formed in the gear, so that the gear can generate eccentric force in the rotation process, is used for transmission and also can be used as an eccentric body, and the vibratory hammer can have high eccentric moment on the premise of not increasing the size of the gear or an eccentric block, can conveniently finish work and has a simple and reasonable structure.
Description
Technical field
The utility model relates to a kind of gear, and more particularly, it relates to a kind of gear of vibration hammer special use.
Background technique
Vibration hammer is widely used on the building site, mainly is the piling for building, and its working principle is that the rotation of two eccentric masss produces vibration, makes object and soil layer on every side separately, reduces surface friction drag, reaches heavy purpose of pulling out.
Vibration hammer generally includes motor, casing, eccentric mass, driving shaft, driven shaft, gear composition, power is to be passed in the casing by the intermeshing master and slave moving axis of a pair of cylindrical gears by v belt by motor, it is equipped with four eccentric masss on the axle, and eccentric mass will produce eccentric moment to satisfy the need of work of vibration hammer.
Gear in the vibration hammer has generally included the gear teeth and mounting hole, and the center of described mounting hole arranges with the axle center of gear is concentric, has been gearing usually in vibration hammer.And in order to strengthen the eccentric moment of vibration hammer, common way is to strengthen the moment of eccentric mass, and this just requires to increase the volume of eccentric mass, the volume of gear, even the volume of whole vibration hammer all can be amid a sharp increase.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model be to provide a kind of can not only carry-over moment when work, can also be used for producing as eccentric body the vibration hammer gear of eccentric moment.
For achieving the above object, the utility model provides following technological scheme: a kind of vibration hammer gear, comprise the gear body, the gear body is provided with the gear teeth and mounting hole, described gear body is provided with eccentric opening, the axle center of the center of described eccentric opening and gear body, the center of eccentric opening and the center of mounting hole are divided equally and are arranged.
By adopting technique scheme, at gear through hole is set, in rotary course, gear just can produce eccentric force, gear can also not increased gear volume or not increase under the prerequisite of eccentric mass volume as eccentric body usefulness in transmission, just can be so that vibration hammer can have larger eccentric moment, thereby finish the work more easily so that vibration hammer is more enough, simple and reasonable.
The utility model further is set to: the coaxial setting in the axle center of described gear body and the center of mounting hole, described eccentric opening is provided with two at least, and is evenly distributed in the circumferential direction of the circle the periphery of mounting hole.
By adopting technique scheme, so that gear can produce larger and more uniform eccentric moment, simple and reasonable.
The utility model further is set to: described eccentric opening is provided with four and evenly distribute in the circumferential direction of the circle and be semicircle shape, and the diameter of described four eccentric openings is identical.
By adopting technique scheme, further so that gear can produce larger and more uniform eccentric moment, simple and reasonable.
Description of drawings
Fig. 1 is the structural representation that the utility model vibration hammer is used gear embodiment;
Fig. 2 is the Application Example schematic diagram of conventional gears in vibration hammer.
Embodiment
Referring to figs. 1 through Fig. 2 the utility model vibration hammer is described further with gear embodiment.
A kind of vibration hammer gear, comprise gear body 1, gear body 1 is provided with the gear teeth 11 and mounting hole 12, and described gear body 1 is provided with eccentric opening 13, the axle center of the center of described eccentric opening 13 and gear body 1, the center of the center of eccentric opening 13 and mounting hole 12 are divided equally and are arranged.
By adopting technique scheme, at gear through hole is set, in rotary course, gear just can produce eccentric force, gear can also not increased gear volume or not increase under the prerequisite of eccentric mass volume as eccentric body usefulness in transmission, just can be so that vibration hammer can have larger eccentric moment, thereby finish the work more easily so that vibration hammer is more enough, simple and reasonable.
The coaxial setting in the center of the axle center of described gear body 1 and mounting hole 12, described eccentric opening 13 is provided with two at least, and is evenly distributed in the circumferential direction of the circle the periphery of mounting hole 12.By adopting technique scheme, so that gear can produce larger and more uniform eccentric moment, simple and reasonable.
Described eccentric opening 13 is provided with four and evenly distribute in the circumferential direction of the circle and be semicircle shape, and the diameter of described four eccentric openings 13 is identical.By adopting technique scheme, further so that gear can produce larger and more uniform eccentric moment, simple and reasonable.
