Abstract

The invention discloses an antenna mast lifting speed reducer gear shifting mechanism. The antenna mast lifting speed reducer gear shifting mechanism comprises an output shaft, an electric input shaftand a manual input shaft, wherein the electric input shaft and the manual input shaft are arranged in parallel to the output shaft. The output shaft is in sliding and engaged connection with a shifting gear. An electric end gear is fixed to the electric input shaft. A manual end gear is fixed to the manual input shaft. The electric end gear and the manual end gear are located in different planes.The shifting gear is fixedly connected with a gear shifting mechanism. The gear shifting mechanism comprises a shifting fork fixedly connected with the shifting gear. The shifting fork is connected with a cam rotating mechanism. The antenna mast lifting speed reducer gear shifting mechanism is convenient to machine, fast and convenient to operate during gear shifting and simple and reliable in structure, and can conveniently switch power sources for lifting an antenna mast as required.

Description

Technical field: [0001] The invention belongs to the field of machinery, in particular to a shift mechanism for an antenna mast lifting reducer. Background technique: [0002] The reducer is a power transmission mechanism that uses the speed conversion of the gear to reduce the speed of the motor to the required speed and obtain a larger torque device. The reducer has a large transmission ratio, a large output torque, and a low speed. , stable transmission, low noise, high output rigidity and so on. It has been widely used in various industries. [0003] The military antenna mast lifting reducer is used for the field antenna lifting of the troops, and is used to send and receive information. When the vehicle has power, the motor can be used as power to raise and lower the antenna mast; when there is no power, switch to manual gear and use the hand crank to raise and lower the antenna mast. The antenna mast lifting reducer on the market adopts a worm gear mechanism, which ...
