Description

Swing arm
Technical field
The present invention relates to the mechanical part field, relate in particular to a kind of swing arm.
Background technique
In the existing mechanical equipment, swing arm has become a very important constituent element, and it is playing the effect of transmit force and moment, thereby it bears the pressure effect 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 on support, rotate, and existing swing arm all has rotary part and is fixed in the arm of force of rotary part outer side surface; In order to guarantee rotary part and arm of force connection stability; The arm of force is welded in the rotary part outer surface, and makes 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 appears in rotary part and arm of force attachment portion regular meeting; Cause the fracture of swing arm, and then cause can't normally using of machinery, cause the certain economic loss.
Therefore, a kind of new swing arm is not proposed to address the above problem again.
Summary of the invention
The invention provides a kind of integrated swing arm.
For solving the foregoing invention purpose, the invention provides a kind of swing arm, said swing arm comprises
The arm of force portion and the arm of relying on oneself be towards extended first rotary part of first direction, and said arm of force portion comprises two relative sides; The said first rotary part outer surface is a circular arc, and said side is a straight line, and said side and the said first rotary part outer surface are tangent.
As further improvement of the present invention, the angle between two sides of said arm of force portion is 25 degree.
As further improvement of the present invention, be provided with first through hole in the middle of said first rotary part, said first through hole is circular.
As further improvement of the present invention, the inner surface of said first through hole is provided with a square breach.
As further improvement of the present invention; Definition is a second direction with first party in the opposite direction; Second rotary part extends towards said second direction in said arm of force portion, and the said second rotary part outer surface is a circular arc, and said two sides and the said second rotary part outer surface are tangent.
As further improvement of the present invention, be provided with second through hole in the middle of said second rotary part, said second through hole is circular.
As further improvement of the present invention, the radius of said second through hole is 1/3rd of the said first through hole radius.
As further improvement of the present invention, the radius of said first through hole is 75 millimeters.
Compared with prior art, swing arm provided by the present invention, its arm of force portion and rotary part are formed in one; And the side of arm of force portion 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 embodiment of the invention or technological scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing relevant of the present invention in describing below only is some embodiments of the present invention, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the side view of swing arm in one embodiment of the invention.
Wherein, reference character is:
Swing arm, 100; Arm of force portion, 10; First rotary part, 11; Second rotary part, 12; First through hole, 111; Square breach, 112; Second through hole, 121.
Embodiment
Below will combine each embodiment shown in the drawings to describe the present invention.But these embodiments do not limit the present invention, and those of ordinary skill in the art all is included in protection scope of the present invention according to the conversion on structure, method or the function that these embodiments made.
Join shown in Figure 1ly, the invention provides a kind of swing arm 100, said swing arm 100 comprises
The arm of force portion 10 and the arm 10 of relying on oneself be towards extended first rotary part 11 of first direction, and said arm of force portion 10 comprises two relative sides; Said first rotary part, 11 outer surfaces are circular arc, and said side is a straight line, and said side and the said first rotary part outer surface are tangent.
Special, the angle between two sides of said arm of force portion 10 is 25 degree.
Wherein, be provided with first through hole 111 in the middle of said first rotary part 11, said 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 said first through hole 111 is provided with a square breach 112, has reduced the weight of first rotary part 11, has reduced the driving swing arm and has rotated required electric power, and is effectively energy-conservation.
Definition is a second direction with first party in the opposite direction, and second rotary part 12 extends towards said second direction in said arm of force portion 10, and said second rotary part, 12 outer surfaces are circular arc, and said two sides and the said second rotary part outer surface are tangent.
Wherein, be provided with second through hole 121 in the middle of said second rotary part, said second through hole 121 is circular, and this second through hole 121 can be accommodated the support upper bearing (metal) that swing arm 100 is mated.
Concrete, the radius of said second through hole 121 is 1/3rd of said first through hole, 111 radiuses, and the radius with two bearings of the correspondence on the coupling support improves the matching degree of swing arm.
Special, the radius of said first through hole 111 is 75 millimeters.
