Embodiment Construction

[0011] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0012] The working principle of the present invention is to design at least three input teeth 4 meshing with the center teeth 3, the transmission ratio between the mutual transmission gears is higher, and the transmission efficiency between the input gears is improved, and then the gear box 1 in front of the inner wall A baffle plate 9 is provided, and a sound insulation panel 12 made of a damping material is added on the outer plate of the baffle plate 9 to improve the sound insulation effect of the whole gear box. ...

Abstract

The invention discloses a sound-insulating gear box, which comprises: a gear box body, an input gear shaft is arranged in the center of the gear box body, one end of the input gear shaft is connected to a central tooth, and at least three outer teeth of the central tooth are engaged. Input teeth, the input teeth mesh with the external gear housing, transition teeth are provided on the other end of the input gear shaft, the transition teeth are meshed with the output teeth, and the output teeth are provided with an output shaft, so A baffle plate is also arranged in front of the inner wall around the gear case body. Through the above method, the present invention can make the transmission ratio between the input gears higher, so that the transmission efficiency of the input gears increases, thereby driving the efficiency of the output gears to increase, and the baffles provided can prevent the lubricant between the gears from splashing, and the baffles also It has sound insulation effect.

Description

technical field [0001] The invention relates to the field of gear boxes, in particular to a high-efficiency sound-insulating gear box. Background technique [0002] The gears in the gear boxes currently on the market usually have a low transmission ratio between the gears, resulting in low transmission efficiency between the gears, so that the efficiency of the gear box is low during operation. And common gear box is not done sound insulation treatment, and when working, the sound is louder, causes certain influence to the user. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a gear box, which can improve the transmission efficiency of the input gear, drive the transmission efficiency of other gears, and perform sound insulation treatment on the gear box. [0004] In order to solve the above-mentioned technical problems, a technical solution adopted by the present invention is to provide a gear box, including: ...
