The utility model content
The purpose of this utility model is to provide a kind of cutter with double saw bits transmission mechanism, and this transmission mechanism has convenience simple in structure, is convenient to install the high advantages such as cutting service life that strengthens of installation accuracy.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: a kind of cutter with double saw bits transmission mechanism, it comprises motor, blade shroud, motor shaft, interior saw blade connecting axle, outer saw blade connecting axle, the motor shaft left and right sides is combined with respectively curved circular bevel gear a and curved circular bevel gear b by wildhaber-novikov gear, curved circular bevel gear a is threaded connection the side at interior saw blade connecting axle afterbody, curved circular bevel gear b is threaded connection a side of saw blade connecting axle afterbody outside, curved circular bevel gear b opposite side is provided with a back-up ring, described interior saw blade connecting axle output is provided with inboard saw blade, inboard saw blade is by straight pin b location, described outer saw blade connecting axle output is provided with outside saw blade and saw blade nut successively, described outside saw blade is by straight pin a location.
Described a kind of pair of saw blade cutting transmission mechanism, be provided with bearing a and bearing b between curved circular bevel gear a and saw blades groups, in bearing a and bearing b, ring is arranged on outer saw blade connecting axle, the output of outer saw blade connecting axle is provided with bearing c and bearing d, bearing d lower end is provided with fin, described back-up ring one side is provided with a bearing e, and bearing e outer shroud is arranged on the saw blade connecting axle of the outside, be provided with a packing ring between bearing e and curved circular bevel gear b, the wildhaber-novikov gear below of motor shaft is provided with a bearing f, and bearing f outer shroud is arranged on motor shaft, described outside saw blade is arranged with blade shroud outward, the blade shroud outside is provided with the blade shroud retaining ring.
Described curved circular bevel gear a is identical with curved circular bevel gear b gear ratio, but the gear opposite direction, thereby make outer saw blade and inner circle saw blade rotate in opposite directions.
Operation principle: electric machine rotation drives curved circular bevel gear a by wildhaber-novikov gear and rotates counterclockwise, and thereby outside being threaded connection drive with outer saw blade connecting axle, saw blade rotates counterclockwise, drive curved circular bevel gear b clockwise rotates simultaneously, thereby be threaded with interior saw blade connecting axle power transmission shaft and drive inboard saw blade and clockwise rotate, thereby adopt identical gear ratio to realize the move toward one another of two saw blades, adopt identical gear ratio, guaranteed relatively synchronous running up between saw blade, reduce the asynchronous excessive risk of a certain single saw blade loss that causes of coping saw blade cutting in cutting process, the ability that has strengthened cutting also guarantees the service life of saw blade simultaneously.
In sum, these utility model characteristics are as follows: this transmission mechanism has convenience simple in structure, interior saw blade transmission shaft and outer saw blade transmission shaft directly are connected on the wildhaber-novikov gear of motor shaft by the curved circular bevel gear respectively, transmission efficiency is high, adopt identical gear ratio, strengthen cutting machine stability, cutting accuracy is high, strengthens saw blade and cuts service life.
