Data output transmission mechanism

Abstract

The invention discloses a data output transmission mechanism. The data output transmission mechanism comprises a data output shaft, a data output gear, a data acquirer connection shifting fork and a power input shaft; the data output shaft and the power input shaft are each a thin-wall sleeve-shaped part; the data output shaft is sleeved with the power input shaft; the upper end and the lower endof the data output shaft are installed in inner holes of the upper end and the lower end of the power input shaft through bearings correspondingly; a power input gear is arranged on the middle portionof the power input shaft, and the power input gear and the power input shaft are fixedly connected in the axial direction through a screw and a positioning pin after being matched through a hole shaft; and the upper end and the lower end of the power input shaft are installed in inner holes of an upper supporting base and a lower supporting base correspondingly through bearings. According to thedata output transmission mechanism, when the space rotating angle information of an orientation mechanism is acquired by means of gear transmission, not only is a clearance eliminating gear structureadopted to eliminate the gear engaging side clearance, but also a speed increasing transmission manner is adopted for data output.

Description

technical field [0001] The invention relates to a data output transmission mechanism, which belongs to the technical field of gear transmission design. Background technique [0002] Gear transmission is widely used in launchers. The transmission device can change the transmission ratio between the power and the slewing mechanism by using the gear transmission, and can also use the gear transmission to stop the slewing mechanism with a large moment of inertia within the required braking angle range, and can also use the gear transmission to obtain the spatial rotation of the azimuth mechanism. angle information. [0003] In the prior art, when the launching device obtains the spatial rotation angle information of the azimuth mechanism through gear transmission, it adopts a deceleration transmission mode that does not eliminate the backlash of gear meshing. Its main shortcomings are manifested in two aspects: one is that the deceleration transmission is Reduce the rotation s...

Problems solved by technology

[0003] In the prior art, when the launching device acquires the spatial rotation angle information of the azimuth mechanism through gear transmission, it adopts a deceleration transmission mode that does not eliminate the backlash of gear meshing. Reduce the rotation speed of the azimuth mechanism before outputting, so the data collector must have a higher sensitivity, otherwise, the accuracy of the spatial rotation angle information of the azimuth mechanism calculated through the data output by the gear transmission will not reach the set value Second, due to the existence of gear meshing backlash, when calculating the spatial rotation angle information of the azimuth mechanism through the data output by the gear transmission in the later stage, necessary technical processing must be performed on the impact caused by the gear meshing backlash, otherwise, all The obtained spatial rotation angle information of the azimuth mechanism is not the real data required
