The invention discloses a landing-gear raising-lowering device. The raising-lowering device comprises a support used for being fixedly connected with a landing gear. A shaft hole is formed in the support. A wheel shaft used for being fixedly connected with an aircraft body is installed in the shaft hole. A sector gear is fixedly installed on the wheel shaft. A worm and gear mechanism driven by a driving mechanism is installed in the support. A worm gear tooth and a synchronous belt gear tooth are arranged on a worm gear shaft of the worm and gear mechanism. The synchronous belt gear tooth is engaged with a gear in a transmission mode through a synchronous belt to form a synchronous belt gear mechanism. The gear fixedly connected with the support is engaged with the sector gear in a transmission mode. The landing-gear raising-lowering device has the advantages that the structure and the functions are integrated, control is easy, working performance is stable and reliable, the manufacturing technology is simple, and maintenance is easy; the requirements for modern small aircraft landing-gear raising-lowering devices are met.
