Problems solved by technology
[0005] However, general printing equipment must transmit power from one side of the base to the other side, requiring the use of movable shafts, which often results in unstable power transmission and affects product quality, or makes the device too complicated and expensive to achieve stable power system; In order to solve this technical problem, it is necessary to design a cantilever transmission device with simple structure and easy assembly to reduce the performance requirements of the bearing, thereby improving the fatigue life and stability of the bearing

Embodiment Construction
[0021] In order to better understand the technical content of the present invention, the specific embodiments are specifically cited and described as follows in conjunction with the accompanying drawings:
[0022] Examples of the present invention are as figure 1 As shown, it includes a shaft 1, a bushing 2, a clutch device 3 for power input, a bearing housing 4, a gear 5 for power output, bearings 6, 7 and a supporting fixed plate 8. The bearing seat 4 is embedded in the base of the machine, and the bearings 6 and 7 are located in the bearing seat 4 as the first support position of the shaft 1. The gear 5 and the shaft 1 are fastened and rotate together through the pin on the shaft 1, and the shaft 1 passes through the bearing. The inner ring and the two are clearance fit. The inner ring of the clutch device 3 is sleeved on the shaft 1 with a D-type fit. The gear structure of the outer ring is connected to the power. When the clutch device is working, the gear structure of th...

The invention provides a cantilever shaft supporting system of a printer. The system includes a shaft, a bushing, a device for providing a power input, a device for providing a power output, and a fixed plate for supporting; the bushing serves as a second supporting level of the shaft, an outer ring of the bushing is a D-type structure, and the bushing is embedded in the fixed plate; and a joint between the shaft and the device for providing the power input and the device for providing the power output is designed to be the D-type structure, or a pins or a key protrusion structure. The cantilever shaft supporting system of the printer of the invention is simple in structure and convenient in assembly, and is stable in transmission power so as to improve the printing quality of the image; the performance requirement for the bearing is reduced; the bearing fatigue life is improved; and the manufacturing and use cost of the printer of the invention is further reduced.
Description
technical field [0001] The invention relates to a cantilever type power transmission device in an imaging device such as a printer, in particular to a cantilever shaft support system of the printer. Background technique [0002] The cantilever transmission device is widely used in the field of printers. It is mainly used in power transmission to solve the problem of transmitting power from one side of the machine base to the other side. It needs to use a movable shaft, which often causes unstable power transmission, especially for non-text printing. Images with grayscale requirements, such as images or photos, will cause image quality degradation, or the device will be too complicated and costly to stabilize the power system. [0003] In this field, a similar patent (application number: 201010281701.9; name: cantilever shaft support device); the device of this patent includes a shaft, a bearing housing, a bearing cap, at least four rolling bearings, two sleeves, two sealing ...
