The model utility content
The utility model technical issues that need to address are: provide a kind of the location, axle center is united two into one with the moment of torsion transmission, and axle center positioning accurate accuracy is high, can effectively reduce the linkage structure of motor output shaft and transmission shaft in the Handheld engraving machine of complete machine noise and cost of production.
for addressing the above problem, the technical solution adopted in the utility model is: the linkage structure of motor output shaft and transmission shaft in Handheld engraving machine, comprise: be arranged on the connecting base in casing, one end of connecting base is fixedly connected with an end of transmission shaft, the other end of connecting base is connected with motor output shaft, concrete linkage structure between connecting base and motor output shaft is: be fixedly installed rectangular spline on motor output shaft, the other end of connecting base is provided with the rectangular spline cover that is used in conjunction with rectangular spline, rectangular spline on motor output shaft and the rectangular spline cover on connecting base are used in conjunction with, the axle center of described rectangular spline cover and transmission shaft and motor output shaft is on same straight line.
Further, the linkage structure of motor output shaft and transmission shaft in aforesaid Handheld engraving machine, wherein, on rectangular spline, the quantity of key tooth is at least one and no more than eight, and the keyway in the rectangular spline cover on connecting base is corresponding with the key tooth on rectangular spline and be used in conjunction with respectively.
the beneficial effects of the utility model: the linkage structure that adopts rectangular spline and rectangular spline cover between connecting base and motor output shaft, played the effect of location, axle center and transmitting torque, such linkage structure unites two into one location, axle center and moment of torsion transmission, make in Handheld engraving machine the structure of driving mechanism simpler, reduced the cost of production of product, and between rectangular spline and rectangular spline cover, the precision of location, axle center is high, good stability, noise when effectively reducing complete machine work, and reduced the housing heating, make the handicraft producer can better carry out chasing.
