A rotating part limit mechanism and its use method

Abstract

The invention discloses a rotating part limiting mechanism and an application method thereof, and belongs to the field of mechanical design. The rotating part limiting mechanism comprises a rotating part, a limiting nail and a fastening part, and further comprises a travel adjusting sleeve and a neutral position sleeve; an arc groove is formed in the rotating part; the circle center of the arc groove is coaxial with the rotating part; a round hole is formed in the side wall of the arc section of the arc groove; the diameter of the round hole is larger than the groove width of the arc groove; the limiting nail is a fixed part, and the axis thereof is positioned on a theoretic arc line of the arc groove; inner holes of the travel adjusting sleeve and the neutral position sleeve can be arranged in a way to match the limiting nail, and are fixed on the limiting nail through the fastening part; the arc groove with the round hole is formed, and is respectively matched with the neutral position sleeve and the travel adjusting sleeve; and the rotating part limiting mechanism realizes limitation of a neutral position and a rotating travel of the rotating part in a time sharing manner according to differences of working conditions, and is simple in structure, low in production cost, short in debugging and adjusting periods, simple in operation and relatively high in practical value.

Description

technical field [0001] The invention belongs to the field of mechanism design in the field of mechanical design, and in particular relates to the positioning technology of rotating parts and its application method. Background technique [0002] In the field of traditional mechanical design, especially in the field of mechanism design, it is often necessary to adjust the neutral position limit of some rotating parts, such as drums, sector wheels, and sector rocker arms, or to limit and adjust their rotation strokes to achieve The motion mechanism is debugged and inspected so that the motion mechanism can meet its operating requirements. In general, take the input or output drum of the aircraft's control system as an example. When it is necessary to limit the neutral position of the drum to facilitate the adjustment of the length or connection relationship of other components in the system, a neutral pin will be used to neutralize it. The position is limited. After the adjust...

Problems solved by technology

This method will complicate the design of the parts, increase the number of parts, and increase the difficulty of debugging. At the same time, if the adjustment of the stroke is to be realized, an adjustable stopper is required, which increases the complexity of the parts and reduces the system. reliability
