Compared with the prior art, the swing arm is integrally formed by the actuating arm and the rotating portion, the side edges of the actuating arm are tangent to the outer surface of the rotating portion, mechanical strength of the swing arm is improved, service life of the swing arm is prolonged, and the swing arm has well market prospects.
Description
Technical field
The utility model relates to the mechanical part field, relates in particular to a kind of swing arm.
Background technique
In the existing machinery, swing arm has become a very important constituent element, and it is playing the effect of transmitting force and moment, thereby it bears pressure-acting in the course of the work for a long time, thereby the mechanical strength of himself is determining the working life of swing arm.
Swing arm is all used with support equipped; and can rotate at support; existing swing arm all has rotary part and is fixed in the arm of force of rotary part outer side surface; for the stability that guarantees that rotary part is connected with the arm of force; the arm of force is welded in the rotary part outer surface; and so that the arm of force perpendicular to the outer side surface of rotary part; yet along with the swing arm increase of service time; bursting apart often can appear in rotary part and arm of force attachment portion; cause the fracture of swing arm; and then cause can't normally using of machinery, cause certain economic loss.
Therefore, a kind of new swing arm is not proposed again to address the above problem.
The model utility content
The utility model provides a kind of integrated swing arm.
For solving above-mentioned model utility purpose, the utility model provides a kind of swing arm, and described swing arm comprises
Arm of force section and the arm of relying on oneself be towards extended the first rotary part of first direction, and described arm of force section comprises two relative sides; Described the first rotary part outer surface is circular arc, and described side is straight line, and described side and described the first rotary part outer surface are tangent.
As further improvement of the utility model, the angle between two sides of described arm of force section is 25 degree.
As further improvement of the utility model, be provided with the first through hole in the middle of described the first rotary part, described the first through hole is circular.
As further improvement of the utility model, the inner surface of described the first through hole is provided with a square breach.
As further improvement of the utility model, definition is second direction with first party in the opposite direction, the second rotary part extends towards described second direction in described arm of force section, and described the second rotary part outer surface is circular arc, and described two sides and described the second rotary part outer surface are tangent.
As further improvement of the utility model, be provided with the second through hole in the middle of described the second rotary part, described the second through hole is circular.
As further improvement of the utility model, the radius of described the second through hole is 1/3rd of described the first through hole radius.
As further improvement of the utility model, the radius of described the first through hole is 75 millimeters.
Compared with prior art, swing arm provided by the utility model, its arm of force section and rotary part are formed in one, and the side of arm of force section and the outer side surface of rotary part are tangent, improve the mechanical strength of swing arm, prolonged the working life of swing arm, had good market prospects.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing relevant of the present utility model in the following describes only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the side view of swing arm among the utility model one embodiment.
Wherein, reference character is:
Swing arm, 100; Arm of force section, 10; The first rotary part, 11; The second rotary part, 12; The first through hole, 111; Square breach, 112; The second through hole, 121.
Embodiment
Below with reference to each embodiment shown in the drawings the utility model is described in detail.But these embodiments do not limit the utility model, and the conversion on the structure that those of ordinary skill in the art makes according to these embodiments, method or the function all is included in the protection domain of the present utility model.
Join shown in Figure 1ly, the utility model provides a kind of swing arm 100, and described swing arm 100 comprises
Arm of force section 10 and the arm 10 of relying on oneself be towards extended the first rotary part 11 of first direction, and described arm of force section 10 comprises two relative sides; Described the first rotary part 11 outer surfaces are circular arc, and described side is straight line, and described side and described the first rotary part outer surface are tangent.
Especially, the angle between two sides of described arm of force section 10 is 25 degree.
Wherein, be provided with the first through hole 111 in the middle of described the first rotary part 11, described the first through hole 111 is circular, and this first through hole 111 can be accommodated the support upper bearing (metal) that swing arm 100 is mated.
The inner surface of described the first through hole 111 is provided with a square breach 112, has reduced the weight of the first rotary part 11, has reduced the driving swing arm and has rotated required electric power, and is effectively energy-conservation.
Definition is second direction with first party in the opposite direction, and the second rotary part 12 extends towards described second direction in described arm of force section 10, and described the second rotary part 12 outer surfaces are circular arc, and described two sides and described the second rotary part outer surface are tangent.
