Description
Technical Field
The utility model relates to a building engineering machine, concretely relates to kinetic energy vibrating device's low resistance eccentric wheel.
Background
The vibration device is a basic engineering device which generates strong exciting force to drive objects into the ground or pull the objects upwards after being connected with kinetic energy. The working principle is that kinetic energy is utilized to drive the paired eccentric wheels to rotate oppositely, so that the transverse centrifugal forces generated by the paired eccentric wheels are mutually offset, the vertical centrifugal forces are mutually superposed, and the gear box generates vertical up-and-down vibration through the high-speed rotation of the eccentric wheels, thereby achieving the purpose of downward or upward depth of an object.
The vibrator in the prior art mainly comprises a motor, a box body, an eccentric wheel, a driving shaft, a driven shaft, a gear and the like. The power is transmitted to the driving and driven shafts in the box body by the motor, and the driving and driven shafts are meshed with each other by a pair of cylindrical gears. The eccentric wheel is in the shape of a semicircular cross section, as shown in fig. 1, the eccentric wheel comprises an eccentric wheel body 1, a central shaft 12 and a central shaft hole 11, the eccentric wheel body 1 is an arc-shaped solid body, and the eccentric wheel is soaked in gear grease during working, so that when the eccentric wheel rotates, the plane part of the eccentric wheel is subjected to the resistance of the gear grease.
Thus, the eccentric wheels of the prior art have also a place to lift.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an eccentric wheel of efficient, low resistance to solve current technical problem.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a low resistance eccentric wheel for building engineering machinery, the eccentric wheel includes an eccentric wheel somatic part, a center pin, a central shaft hole and an arc piece, the eccentric wheel somatic part is connected the arc piece, the eccentric wheel somatic part with the arc piece surrounds and forms 360 degrees of outer surface eccentric in the circle.
The low resistance eccentric wheel of the preferred embodiment of this application, the eccentric wheel still includes an arc film, the arc film sets up the gear is kept away from to the arc film one end, the arc film with eccentric wheel body's terminal surface forms outer 360 degrees in the circle vacuum eccentric.
The design theory of this application is, designs a surface and is a whole cylindrical, and inside has the cylinder of vacancy inside to be the vacuum state eccentric wheel, and inside has the vacancy to make its eccentric function that keeps the eccentric wheel, and apparent complete resistance that then can not produce the face with the gear grease realizes low resistance operation, reaches safe operation, saves power and reduces the effect of spending, improves enterprise market competition.
Owing to adopted above technical scheme, make the utility model discloses following advantage effect has:
firstly, the eccentric wheel runs at low resistance, so that the safe running is achieved, the power is saved, the energy consumption and the noise are reduced, the environment-friendly effect is improved, and the market competitiveness of enterprises is improved;
secondly, this application structure is reliable resistance low, long service life.
Of course, implementing any particular embodiment of the present disclosure does not necessarily have all of the above technical advantages at the same time.

Detailed Description
For the purpose of understanding, the preferred embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 2, the present application relates to a low resistance eccentric for construction machinery, the eccentric comprises an eccentric body 10, a central shaft 20, a central shaft hole 21 and an arc-shaped plate 30, the eccentric body 10 is connected to the arc-shaped plate 30, and as shown in the figure, the eccentric body 10 and the arc-shaped plate 30 surround to form an inner circle eccentricity of 360 degrees on the outer surface. In the figure, the arc-shaped sheet 30 is an arc-shaped surface generated by hollowing a part of a cylinder, the outer surface is a complete circle, and the complete outer surface does not generate resistance with gear grease, so that the low-resistance running of the eccentric wheel is realized.
Preferably, the eccentric wheel further comprises an arc-shaped bottom plate (not shown), the arc-shaped bottom plate is arranged at one end of the arc-shaped plate 30 far away from the gear 40, and the arc-shaped bottom plate and the end surface of the eccentric wheel body 10 form an inner vacuum inner eccentric of 360 degrees outside the circle. The arc-shaped bottom plate can prevent gear oil from entering a space formed between the arc-shaped plate 30 and the eccentric wheel body 10, and the resistance influence of the gear oil is reduced. The arc bottom plate can be a bottom surface reserved when the cylinder is hollowed, or can be connected after being processed and formed additionally, such as screw locking, rivet riveting and the like; when the eccentric is coupled to gear 40, the eccentric appears as a cylinder.
This application designs a surface and is a whole cylindrical, and inside has the cylindric eccentric wheel of vacancy, and inside vacancy makes its eccentric function that keeps the eccentric wheel, and apparent complete cylindrical then can not produce the resistance of face with gear oil, realizes the low resistance operation, saves the effect that power reduces the cost.
Owing to adopted above technical scheme, make the utility model discloses following advantage effect has:
firstly, the eccentric wheel runs at low resistance, so that the safe running is achieved, the power is saved, the energy consumption and the noise are reduced, the environment-friendly effect is improved, and the market competitiveness of enterprises is improved;
secondly, this application structure is reliable resistance low, long service life.
Of course, it is not necessary to implement any particular embodiment of the present invention to achieve all of the above technical effects at the same time.
The above disclosure is only for the preferred embodiment of the present invention, but not intended to limit itself, and those skilled in the art can make variations and changes equally without departing from the spirit of the present invention, and all such variations and changes are deemed to fall within the scope of the present invention.
