Angular-linear displacement conversion pull rope encoder and angular-linear displacement conversion method

The invention discloses an angular-linear displacement conversion pull rope encoder and an angular-linear displacement conversion method. The angular-linear displacement conversion pull rope encoder comprises a shell, a tape shaft system and a constant-force spring shaft system are arranged in the shell side by side, an angle encoder is arranged on the tape shaft system, the tape shaft system is connected with the constant-force spring shaft system through a narrow band, and a zero mark point is arranged on the angle encoder. The pull rope encoder solves the problem that an existing wide-range pull rope encoder is large in longitudinal size. 本发明公开了角-线位移转换拉绳编码器及角-线位移转换方法，包括外壳，外壳内并列设置有尺带轴系、恒力弹簧轴系，尺带轴系上设置有角度编码器，尺带轴系与恒力弹簧轴系通过窄带连接，角度编码器上设置有零位标记点。本发明拉绳编码器解决了现有大量程拉绳编码器纵向体积较大的问题。
