Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1-5, the present invention provides a technical solution: a low-noise speed reducer comprises a shell 1, a base 2 and a first sleeve 3, wherein the base 2 is installed at the bottom of the shell 1, first through holes 8 are respectively formed in the front side wall and the rear side wall of the shell 1, second through holes 9 are respectively formed in the front side wall and the rear side wall of the shell 1, first mounting holes 11 are respectively formed in the positions, corresponding to the first through holes 8 and the second through holes, of the front side wall and the rear side wall of the shell 1, a third through hole 10 is formed in the top of the shell 1, a second mounting hole 12 is formed in the position, corresponding to the third through hole 10, of the top of the shell 1, the first sleeve 3 is sleeved at the position, corresponding to the third through hole 10, of the top of the first sleeve 3, a first screw hole 5 is formed in the position, corresponding to the first through hole 8 and the second through hole, of the front side wall and the rear, and a second screw hole 6 is formed in the position, corresponding to the first mounting hole 11, of one side of the second sleeve 4, which is far away from the shell 1.

In this embodiment (please refer to fig. 1 and fig. 4), the combination of the integrated speed reducer casing 1 and the first sleeve 3 and the second sleeve 4 avoids noise generated by collision of too many combinations of components, reduces noise sources during operation of the speed reducer, and reduces noise of the speed reducer.

The bulges 7 are arranged on the side wall of the inner cavity of the shell 1, and the bulges 7 are honeycomb-shaped bulges.

In this embodiment (see fig. 2), when the speed reducer operates and noise is generated inside, the honeycomb-shaped protrusions 7 on the side wall of the inner cavity of the housing 1 allow sound waves to collide with the side wall of the housing 1, so that sound loss is caused, and the noise is reduced in the noise transmission process.

A gasket 13 is arranged between the bottom of the first sleeve 3 and one side of the second sleeve 4 close to the housing 1 and the top of the housing 1, and through holes 14 are formed in positions of the gasket 13 corresponding to the first mounting hole 11 and the second mounting hole 12.

Wherein the first and second casings 3, 4 are T-section casings.

In this embodiment (see fig. 5), the gap between the casing and the casing 1 is filled up by the spacers between the first casing 3, the second casing 4 and the casing 1, so as to prevent the casing from colliding with the casing 1 and generating noise.

Wherein, the base 2 is an inverted U-shaped base.

In this embodiment (see fig. 2), a gap is left between the speed reducer and the mounting plane through the inverted U-shaped base 2, so that the contact between the speed reducer and the solid is reduced, and the propagation speed of sound waves in the gas is slower than that in the solid, so that the propagation speed of sound is reduced.

When the low-noise speed reducer is used, the combination of the integrated speed reducer shell 1 and the first sleeve 3 and the second sleeve 4 avoids the noise generated by mutual collision of excessive component combinations, reduces the noise source when the speed reducer runs, meanwhile, the spacers between the first sleeve 3, the second sleeve 4 and the shell 1 fill up the gap between the sleeves and the shell 1, so that the noise generated by the collision between the sleeves and the shell 1 is avoided, the honeycomb-shaped bulge 7 on the side wall of the inner cavity of the shell 1 runs in the speed reducer, when the noise is generated inside, the sound waves can collide with the side wall of the shell 1 inside to cause sound loss, noise is reduced in the noise transmission process, the inverted U-shaped base 2 enables a gap to be reserved between the speed reducer and the installation plane, contact between the speed reducer and a solid is reduced, the transmission speed of sound is reduced due to the fact that the transmission speed of sound waves in gas is slower than that of the sound waves in the solid, and noise reduction of the speed reducer is achieved. The device simple structure, the operation of being convenient for, the practicality is strong.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above, it will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, but that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.
