Abstract
The utility model discloses a high-strength eccentric shaft, which comprises an eccentric shaft rod body (1), a left eccentric shaft body (2) and a right eccentric shaft body (3); the left eccentric shaft body (2) and the right eccentric shaft body (3) are respectively arranged at two ends of the eccentric shaft rod body (1); flat-key grooves (4) are also formed on the left eccentric shaft body (2) and the right eccentric shaft body (3); axial leads of the left eccentric shaft body (2) and the right eccentric shaft body (3) are on the same straight line; and hanging screw holes (5) are formed at the ends of the left eccentric shaft body (2) and the right eccentric shaft body (3). Due to adoption of the structure, the axial leads of the left eccentric shaft body and the right eccentric shaft body are on the same straight line, thereby greatly reducing the force moment consumed by the torsion, and preventing the eccentric shafts from cracking, breakage and fracture to a certain extent.
Description
Technical field
The utility model relates to the axial workpiece field, is a kind of high strength eccentric shaft that is used for applications such as edge mill, grouter, large-scale intermittent movement working machine specifically.
Background technique
Generally all need to use eccentric shaft in edge mill, grouter, the large-scale fields such as the motion working machine of having a rest of asking, the eccentric shaft of prior art generally comprises the eccentric shaft body of rod, left avertence axle body, right avertence axle body, described left avertence axle body and right avertence axle body are separately positioned on the two ends of the eccentric shaft body of rod, also be provided with the flat key groove on left avertence axle body and the right avertence axle body, the shaft axis of described left avertence axle body and right avertence axle body is not generally on same straight line.Using large-scale edge mill when (as grinding stone machine etc.), because object (as the stone) volume ratio that will be pulverized is bigger, common eccentric shaft because left avertence axle body and right avertence axle body not on same straight line, it is relatively large to reverse the moment that is consumed, and occur crackle, breakage or fracture easily, had a strong impact on job scheduling.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of work moment big high strength eccentric shaft.
Technical solution of the present utility model is, a kind of high strength eccentric shaft of following structure is provided, comprise the eccentric shaft body of rod, left avertence axle body, right avertence axle body, described left avertence axle body and right avertence axle body are separately positioned on the two ends of the eccentric shaft body of rod, also be provided with the flat key groove on left avertence axle body and the right avertence axle body, its feature is that the shaft axis of described left avertence axle body and right avertence axle body is on same straight line.
Adopt above structure, the utility model compared with prior art has the following advantages: adopt the utility model structure, because the shaft axis of described left avertence axle body and right avertence axle body is on same straight line, so just reduced to reverse the moment that is consumed greatly, and prevented that to a certain extent crackle, breakage, fracture from appearring in eccentric shaft.
As improvement, the end of described left avertence axle body and right avertence axle body is provided with the suspention screw, because this type of eccentric shaft is relatively large, carrying is difficulty, and the suspention screw can be used for lifting by crane and certain eccentric shaft by being provided with.

Fig. 3 is the left view of the utility model high strength eccentric shaft.
As shown in the figure 1, the eccentric shaft body of rod, 2, left avertence axle body, 3, right avertence axle body, 4, the flat key groove, 5, the suspention screw.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
High strength eccentric shaft of the present utility model, comprise the eccentric shaft body of rod 1, left avertence axle body 2, right avertence axle body 3, described left avertence axle body 2 and right avertence axle body 3 are separately positioned on the two ends of the eccentric shaft body of rod 1, also be provided with flat key groove 4 on left avertence axle body 2 and the right avertence axle body 3, its feature is that the shaft axis of described left avertence axle body 2 and right avertence axle body 3 is on same straight line; The end of described left avertence axle body 2 and right avertence axle body 3 is provided with suspention screw 5.
Claims (2)
1. high strength eccentric shaft, comprise the eccentric shaft body of rod (1), left avertence axle body (2), right avertence axle body (3), described left avertence axle body (2) and right avertence axle body (3) are separately positioned on the two ends of the eccentric shaft body of rod (1), also be provided with flat key groove (4) on left avertence axle body (2) and the right avertence axle body (3), it is characterized in that: the shaft axis of described left avertence axle body (2) and right avertence axle body (3) is on same straight line.
