Embodiment Construction

[0019] Preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0020] Such as figure 1 To such as Figure 4 As shown, the X axis is the axial direction of the input shaft and the output shaft, and the Y axis is the radial direction.

[0021] The output shaft 3 is supported on the output shaft housing 1 through the output shaft bearing 2 and can rotate relative to the output shaft housing 1 . The output shaft 3 has an end surface tooth structure 12 . The sliding shaft 5 is connected with the sleeve 4 through a spline 14 and can slide relative to the sleeve 4 along the X-axis. There is a tooth structure 12 on the end surface of the sleeve 4, which can engage with the tooth structure 12 on the end surface of the output shaft 3. The wing nut 8 is fixed on the outside of the sliding shaft 5, and the disc spring 6 is connected to the sleeve 4 and the wing nut 8 at both ends along the X-axis. The sliding shaft 5 is ...

Abstract

A self-lock type engaging and disengaging device comprises a belt speed reducer motor, pin drive structures, pin structures, a sliding disc, an input shaft, a sliding mechanism and an output shaft structure. The belt speed reducer motor drives the two pin structures to move along the Y axis through the pin drive structures. The pin structures move along the Y axis to drive the sliding disc to slide along the X axis and then drive the sliding mechanism to slide along the X axis, and finally engaging and disengaging between the sliding mechanism and the output shaft structure are achieved through sliding of the sliding mechanism along the X axis. The self-lock type connecting and disconnecting device has the advantages of being rapid in engaging and disengaging, large in transmitting torque and capable of achieving the self-lock keeping state after outage and meanwhile, has the beneficial effects of being simple in structure and low in weight.

Description

technical field [0001] The invention belongs to the technical field of mechanical transmission clutch, in particular to a self-locking clutch device for transmission engagement and disconnection of a spacecraft. Background technique [0002] At present, in the known space vehicle mechanical transmission devices, the switching of power transmission is mostly realized by electromagnetic clutches. There are two working modes of the clutch: one is energized to engage, and the other is energized to disconnect. Both methods require energization to operate the engaged or disengaged state. If the aircraft needs to maintain this state for a long time, it needs to be powered on all the time, which consumes a lot of electric energy, which is a big waste for spacecraft with relatively tight energy supply. Contents of the invention [0003] In order to solve the problem in the prior art that a large amount of electric energy is required to maintain the clutch state, the present invent...
