Embodiment Construction
[0021] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0022] The purpose of the present invention is to provide a two-way reverse transmission backstop device, which can be used as a shaft coupling to realize normal output when the driving shaft drives the driven shaft, and when the driven shaft reversely drags the driving shaft, both clockwise / counterclockwise The reverse drive in both directions is backstopped.
[0023] The housing 2 of the two-way reverse transmission backstop device is fixed, and the double-sided rollers 4 are pressed by the spring pressure piece 5 to realize the wedging of the rollers 4, the casing 2 and the driven wheel 3, and the two-way reverse transmission backstop is realized; During transmission, the roller 4 is pushed aside by the claw of the driving wheel 1 to realize forward normal transmission.
[0024] like figure 1 Shown is a schematic diagram of a two-way anti-t...

The invention discloses a bidirectional reverse transmission back stop device, and relates to the field of mechanical transmission. The bidirectional reverse transmission back stop device comprises adriving wheel, a shell, a driven wheel, eight rollers, four spring pressing pieces and screws; the driving wheel and the driven wheel are in butt joint in the axial direction, and the four spring pressing pieces are evenly distributed on the side wall of the driven wheel in the circumferential direction; the spring pressing pieces are fixedly connected with the driven wheel through the screws, thetwo sides of all the spring pressing pieces are each provided with the corresponding roller, and the rollers are arranged between the spring pressing pieces and the driven wheel; the shell sleeves the outer walls of the rollers and is located at the butt-joint position of the driving wheel and the driven wheel; the shell of the bidirectional reverse transmission back stop device is fixed, and therollers on the two sides are pressed through the spring pressing pieces to achieve wedge-caulking between the rollers and the shell as well as between the rollers and the driven wheel so as to achieve bidirectional reverse transmission back stop; during forward transmission, the rollers are shifted away through a shift claw of the driving wheel to achieve forward normal transmission; and when a driving shaft drives a driven shaft, normal output is achieved, and when the driven shaft reversely drags the driving shaft, reverse transmission in two directions of the clockwise direction and the anticlockwise direction is back stopped.
Description
technical field [0001] The invention relates to the field of mechanical transmission, in particular to a bidirectional reverse transmission backstop device. Background technique [0002] When the electromechanical actuator pushes the aircraft cargo door open / close to any position, it requires reliable locking to prevent the door from falling and hurting people. It is necessary to design a two-way reverse drive backstop device. If transmission devices such as trapezoidal screw and worm gear are used, self-locking can realize bidirectional reverse transmission and backstop, but the transmission efficiency of this scheme is too low to realize light weight and miniaturization of electromechanical actuators. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art, and provide a two-way anti-transmission backstop device, which realizes normal output when the driving shaft drives the driven shaft, an...
