Problems solved by technology

[0003] The existing powertrain part manufacturing is extremely complicated, but it is extremely difficult to guarantee the accuracy, and the installation and accuracy adjustment are very complicated. Due to the limited space of the structure, the reducer in front of the motor must also choose a smaller link flange to ensure the structure. The result is that the overall installation structure of the motor is uncoordinated, and there is unstable shaking during rapid movement, so that the overall structural accuracy cannot be maintained and guaranteed for a long time. In the power transmission of this structure, the output of the motor After the reducer, the coupling, and the shaft are connected, and the power in it is transmitted by a single key. After a long time, the key gap will increase, the transmission accuracy will decline, and frequent maintenance will occur.

Abstract

The invention discloses a printing unit transmission set based on a shaftless motor. The printing unit transmission set comprises the motor, a spline, a rotating shaft, a motor base and a shaft barrel, a motor flange is installed at one end of the motor base, and a movable ring is fixedly installed at one end of the inner surface of the motor base. The motor is arranged, spline connection is adopted for outputting power, connection stress is uniform, meanwhile, motor abrasion is reduced, the shaft barrel and the motor base are both cylindrical parts, the advantages of being easy to machine and high in precision are achieved, meanwhile, the motor is convenient to install, precision is improved, a transmission route is simplified, the characteristics of the motor are fully applied, by arranging a sliding sleeve and the movable ring, the flexibility of rotation is achieved, small-gap flexible movement during stretching and retracting of a rotating shaft is guaranteed, separation of movement and rotation is achieved, a bearing is arranged to guarantee overall rotation and bear radial pressure, a transmission route is greatly optimized, the structure is optimized, the overall precision is improved on the basis that cost is saved, ad later disassembly and maintenance are convenient.

Description

technical field [0001] The invention relates to the technical field of a printing unit transmission group, in particular to a printing unit transmission group based on a shaftless motor. Background technique [0002] In the existing universal printing unit, the transmission power of the printing plate and the horizontal installation size and adjustment of the plate are concentrated in the power assembly part, but the existing power assembly part has the following defects: [0003] The existing powertrain part manufacturing is extremely complicated, but it is extremely difficult to ensure the accuracy, and the installation and accuracy adjustment are very complicated. Due to the limited space of the structure, the reducer in front of the motor must also choose a smaller link flange to ensure the structure. The result is that the overall installation structure of the motor is uncoordinated, and there is unstable shaking during rapid movement, so that the overall structural acc...
