The utility model is achieved in that a kind of mini engine bent axle of structure, it is characterized in that: comprise connecting end, conical section, two eccentric part; Described conical section front end is axle head, and be provided with tool withdrawal groove between axle head and conical section, be column part in the rear end of conical section, it is the front support end that diameter is greater than column part in the rear end of column part, front support end rear end is two identical eccentric part, between two eccentric part, be provided with an attachment portion, rear end, attachment portion is rear support end, is connecting end at rear support end afterbody.Ensure that convenient installation of the present utility model by reasonably designing conical section, described front and back support end is for bearings mounted, reliable and stable during guarantee utility model works; Described eccentric part is taken turns for setting-up eccentricity.The central axis of described eccentric part and other segment axis are not on the same line.
According to mini engine bent axle described in the utility model, it is characterized in that: described front support part, attachment portion and two eccentric part joints are all rounded down.Described chamfering fillet is the generation in order to prevent concentrated stress, ensures Rigidity and strength of the present utility model.
According to mini engine bent axle described in the utility model, it is characterized in that: the connecting end being positioned at rear support end afterbody offers rectangle keyway; Being for installing square key at the rectangle keyway of connecting end, ensureing that the utility model can better be connected also transferring power with power section.
The utility model tool has the following advantages: mini engine bent axle described in the utility model; It one of improves; Ensure that convenient installation of the present utility model by reasonably designing conical section, described front and back support end is for bearings mounted, reliable and stable during guarantee utility model works; Described eccentric part is taken turns for setting-up eccentricity.The central axis of described eccentric part and other segment axis are not on the same line.
Two of its improvement is; Front support part, attachment portion and two eccentric part joints are all rounded down; The benefit of its chamfering fillet is the generation in order to prevent concentrated stress, ensures Rigidity and strength of the present utility model.
Three of its improvement is; The connecting end being positioned at rear support end afterbody offers rectangle keyway; Being for installing square key at the rectangle keyway of connecting end, ensureing that the utility model can better be connected also transferring power with power section.
The utility model global design is reasonable, and structure is simple, by the rational design of every part ensure that this bent axle stable and reliable for performance, transmission is accurate; The utility model is installed simple simultaneously, and convenient disassembly, seems very convenient in maintenance afterwards; The utility model is by reasonably designing the distance of eccentric part center line and other segment centerline, and ensure that the utility model is more accurate in the process medium power transmission of work, orientation is more reliable.
