Problems solved by technology

[0003] However, when the transmission mechanism in the existing gearbox needs the external ring gear to output large torque, the strength of the gear is insufficient, the structure is not compact, the gearbox is prone to broken teeth and shafts, and the transmission stability is poor. Operation in the environment will generate a lot of noise

Abstract

The invention discloses an A+B gearbox integrating structure. The A+B gearbox integrating structure comprises an A gearbox body and a B gearbox body, wherein an A box bottom plate is mounted at one end of the A gearbox body, and an A box cover plate is mounted at the other end of the A gearbox body; a B box bottom plate is mounted at one end of the B gearbox body, and a B box cover plate is mounted at the other end of the B gearbox body; a plurality of positioning pins are mounted between the A box cover plate and the B box bottom plate; a rolling bearing which sleeves an output shaft is positioned at one end of the A box cover plate and is rotatably connected into the A gearbox body; a first tooth groove is arranged in one end of the output shaft and is formed in the B gearbox body; a supporting sleeve sleeves an inner hexagonal screw, and a long planetary gear sleeves the supporting sleeve; a second tooth groove is formed in the inner wall of the B gearbox body; and the first tooth groove and the second tooth groove are correspondingly engaged with the long planetary gear. The A+B gearbox integrating structure is high in structure strength, capable of bearing high torque, stableto transmit, and small in noise while running in high-speed and heavy load conditions.

Description

technical field [0001] The invention relates to the technical field of gearboxes, in particular to an A+B gearbox complete structure. Background technique [0002] The gear box is generally used in the up and down adjustment mechanism of the back of the medical bed. [0003] However, when the transmission mechanism in the existing gearbox needs the external ring gear to output large torque, the strength of the gear is insufficient, the structure is not compact, the gearbox is prone to broken teeth and shafts, and the transmission stability is poor. Operating in the environment will generate a lot of noise. Contents of the invention [0004] The object of the present invention is to propose a complete structure of A+B gear box in order to solve the shortcomings in the prior art. [0005] In order to achieve the above object, the present invention adopts the following technical solutions: [0006] A complete structure of A+B gear box, including A gear box body and B gear ...
