A multi-speed reducer switched by double-taper screw

Abstract

The invention discloses a multi-speed reducer switched by a double-taper screw. The multi-speed reducer comprises: a box body, a central shaft and an output shaft arranged in the box and connected in rotation, from one end of the central shaft to the other A torque motor, a fixed cone, a double-cone slider, a sun gear and a planetary carrier are nested in sequence at one end, and planetary gears and epicyclic gears are arranged on the side wall of the sun gear in sequence from the inside to the outside, and are nested on the double-taper slider. The block and the friction cone on the epicyclic gear, the micro switch fixedly arranged on the side wall of the box and above the double cone slider, and the control end electrically connected with the micro switch. Among them, the central axis of the box, the central shaft and the output shaft are at the same position; the end of the torque motor is fixedly connected to the end of the fixed cone, and the end of the double-cone slider is fixedly connected to the end of the epicyclic gear. The end of the cone is fixedly connected with the end of the planet carrier. The speed reducer of the invention has small and exquisite structure, compact structure, reliable braking and low energy consumption during braking.

Description

technical field [0001] The invention relates to a reducer, in particular to a multi-speed reducer switched by a double-taper screw. Background technique [0002] At present, most mechanical devices that rely on motion to work generally have two common working states. One is high-speed operation under low load conditions; the other is low-speed operation under heavy load conditions. Therefore, when the two working states are converted to each other, whether the control is convenient and fast, and whether the conversion is smooth are important indicators for evaluating the efficiency of the conversion mechanism. [0003] The existing reducers are: single-stage or multi-stage planetary reducer, and electromagnetic control switching reducer. [0004] As for the planetary reducer, its structure is compact, the reduction ratio is large, and it can realize various speed outputs, so it is widely used. The single planetary gear reducer is mainly composed of sun gear, planetary gea...
