Problems solved by technology

[0003] Many reducers in the prior art will produce a lot of noise during use, and these noises will cause great harm to the operators of the equipment, which is not conducive to the normal work of the staff. This is one of the existing technologies. Big deficiency; In addition, some noise reduction devices in the prior art will greatly affect the overhaul and maintenance operations of the reducer in the later stage after installation, which is not conducive to the normal use and operation of the reducer. This is the existing technology Therefore, based on the reason of use, the present invention proposes a high-efficiency noise reduction structure for the reducer to solve these deficiencies

Embodiment 1

[0025] see Figure 1-7 , a high-efficiency noise reduction structure for a reducer, a high-efficiency noise reduction structure for a reducer, comprising a lower sealing cover 1 and an upper sealing cover 2, and the outer walls on both sides of the lower sealing cover 1 and the upper sealing cover 2 are fixedly installed with a first connection The plate 3 and the second connecting plate 4, the first connecting plate 3 and the second connecting plate 4 are all provided with fixing holes, and the lower sealing cover 1 and the upper sealing cover 2 are fixedly installed with an arc-shaped storage table 5. The arc-shaped storage The surface of the table 5 is provided with a reducer input shaft 7 and a reducer output shaft 8, a reducer body 6 is arranged between the reducer input shaft 7 and the reducer output shaft 8, and the outer walls of the reducer input shaft 7 and the reducer output shaft 8 are both. A fixed shock absorbing device 9 is sleeved, and the fixed shock absorbing...

Embodiment 2

[0028] see Figure 7 , On the basis of the first embodiment, a sealing ring 12 is arranged between the lower sealing cover 1 and the upper sealing cover 2, and the inner diameter of the sealing ring 12 matches the outer diameter of the reducer input shaft 7 and the reducer output shaft 8. , the sealing ring 12 and the arc-shaped stage 5 are provided with parallel fixing holes. The sealing ring 12 is made of elastic sound-absorbing material. The use of the lower sealing cover 1, the upper sealing cover 2 and the sealing ring 12 can effectively reduce the operation of the reducer. The phenomenon that the noise is transmitted to the outside world improves the protection of the staff; the inner side wall of the lower sealing cover 1 is fixedly installed with a sound-absorbing pad 13, the sound-absorbing pad 13 is made of foam metal, the surface of the sound-absorbing pad 13 is wavy, and the sound-absorbing pad 13 It can absorb the noise generated when the machine is working, and the...

Abstract

The invention discloses an efficient noise reduction structure for a speed reducer, and relates to the technical field of speed reducer noise reduction, in particular to the efficient noise reduction structure for the speed reducer, which comprises a lower sealing cover and an upper sealing cover, and a first connecting plate and a second connecting plate are fixedly mounted on the outer walls of the two sides of the lower sealing cover and the upper sealing cover; fixing holes are formed in the first connecting plate and the second connecting plate correspondingly, arc-shaped storage tables are fixedly installed in the lower sealing cover and the upper sealing cover correspondingly, a speed reducer input shaft and a speed reducer output shaft are arranged on the surfaces of the arc-shaped storage tables, and a speed reducer body is arranged between the speed reducer input shaft and the speed reducer output shaft. The power input shaft and the outer wall of the input shaft of the speed reducer are sleeved with the arc-shaped fixing frames, noise generated by shaking in the use process of the speed reducer can be reduced while effective shock absorption can be achieved, and meanwhile the phenomenon that the noise is diffused to the outside can be effectively reduced by designing the sound absorption pad on the inner wall of the lower sealing cover.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to a high-efficiency noise reduction structure for a reducer. Background technique [0002] In the daily life of machinery manufacturing and the production of various equipment, the reducer is required. The reducer is an independent component composed of a gear drive, a worm drive, and a gear-worm drive enclosed in a rigid casing. It is a deceleration transmission device between the prime mover and the working machine, which plays the role of matching the rotational speed and transmitting torque between the prime mover and the working machine or the actuator, and is widely used in modern machinery. [0003] Many reducers in the prior art will generate a lot of noise during use, and these noises will cause great harm to the operators of the equipment and are not conducive to the normal work of the staff. This is one of the prior art. There is a big disadvantage; in addition, some n...
