Embodiment Construction

[0021] Below in conjunction with specific embodiment and contrast appendix Figures 1 to 3 The present invention is described in further detail. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0022] A shaft coupling applied to a tilting speed change flywheel includes an inner shaft 1 and an outer shaft sleeve 2 composed of rotating bodies, as shown in figure 1 and figure 2 shown. The inner shaft 1 has a cylindrical shape as a whole, one of which has a small boss 1-2 with a through hole, and a blind hole on the other side, and a cutting groove 1-1 at a symmetrical position in the radial direction. Orthogonally and alternately distributed upwards, wherein the depth of the blind holes is slightly greater than the total axial length of the cutting groove. One side of the outer shaft sleeve 2 is a flange-like structure 2-2, and a plurality of through holes are evenly distribut...

Abstract

The invention discloses a coupler applied to a tilt variable speed flywheel, and relates to the technical field of couplers. The coupler is applied to the tile variable speed flywheel. The problem that an existing coupler applied to a tilt variable speed flywheel causes unstability of a rotor is solved. The coupler comprises an inner shaft and an outer shaft sleeve with which the inner shaft is sleeved, one end face of the inner shaft is provided with a small boss with a through hole, the other end of the inner shaft is provided with a blind hole, the blind hole communicates with the through hole in the small boss, cutting slots are formed in the symmetrical positions on the side wall of the inner shaft in the circumferential direction, and the cutting slots are alternately distributed inan upward-orthogonal mode; and a flange-shaped structure used for being connected with the rotor is arranged on the outer side of one end of the outer shaft sleeve, cutting slots are formed in the symmetrical positions on the side wall of the outer shaft sleeve in the circumferential direction, and the cutting slots are alternately distributed in an upward-orthogonal mode. The design structure iscomposed of only two parts, positioning precision of two-shaft connection is improved, assembling work procedures are reduced, and the whole device is more compact in layout.

Description

technical field [0001] The invention relates to the technical field of shaft couplings, in particular to a shaft coupling applied to a tilting speed change flywheel. Background technique [0002] As a new type of momentum exchange device, the tilting variable speed flywheel is inspired by the dynamic tuning gyroscope. It can not only provide angular momentum bias for the spacecraft, but also output three-axis angular momentum while measuring the angular rate of two axes. control torque. A coupling is a mechanical part used to connect two shafts in different mechanisms so that they rotate together to transmit torque. At present, the flexible support in the tilting variable speed flywheel and the power tuning gyroscope is a kind of coupling. It is One of the key components of the device. The flexible support connects the rotor with the drive shaft, and the motor drives the drive shaft to move the rotor at high speed through the flexible support to generate angular momentum. ...
