Reducing machine noise processing method

Gear transmission schematic The noise generation of the Cycloidal reducers is mainly due to the friction, vibration and collision of the transmission gear, how to effectively reduce and reduce the noise, make it more environmentally friendly requirements is also a key research topic at home and abroad.
Reducing the gear transmission noise of the parallel shaft helical gearbox has become an important research topic in the industry. Many scholars at home and abroad regard the change of the meshing stiffness of the gear in the gear transmission as the main factor of the dynamic load, vibration and noise of the gear. With the modified method, so that the dynamic load and speed fluctuations to a minimum, in order to achieve the purpose of reducing noise. This method proved to be a more effective method in practice. But with this method, the process needs to have modified equipment, the majority of small factories are often unable to implement.
After years of research, it is proposed that by optimizing the gear parameters such as the displacement coefficient, the tooth height coefficient, the pressure angle and the center distance, the meshing impact velocity is reduced to a minimum, and the ratio of the outburst impact velocity to the hitting impact velocity is at a certain value Range, to reduce or avoid the impact of the pitch circle gear design method, but also significantly reduce the gear unit gear noise.

Reducer type

The high torque gearbox is a relatively sophisticated machine that uses its purpose to reduce the speed and increase the torque. It has a wide variety of models, different types, different types have different uses.
There are many kinds of reducer, according to the type of transmission can be divided into worm reducer gearbox, worm reduction and planetary gear reducer; according to the different transmission stages can be divided into single and multi-stage reducer; according to the shape of the gear can be divided into cylindrical gear Reducer, Cycloidal Speed Reducer Gearbox and conical - cylindrical gear reducer; in accordance with the transmission layout can be divided into expansion, split and coaxial reducer.

Special reducer, is dedicated to specific areas and industry reducer.

variable speed electric motor types are mill reducer, oilfield double word arc gear special reducer, wind turbine with speed changer, planetary differential gear reducer, planer with planetary gear reducer, hardened gear reducer, Deepening reducer, combination worm gearbox for oil extraction machine, special reducer for irrigation machine, reducer for screw conveyor, reducer for asphalt mixer, reducer for reducer, Flying shear machine and so on.
Application areas: advantages of variable speed drives is widely used in metallurgy, mining, lifting transport, electricity, energy, building materials, light industry, transportation and other fields.

Brief introduction of combined reducer

WAH hypoid gearbox, that is, to meet the needs of different operations, according to a certain principle to combine two or more components used in the reducer.
Common combination series with CVT series stepless, WJ series reducer combination; Universal modular reducer, UDL and NMRV combination reducer, PC and NMRV reducer combination, NMRV and NMRV combination reducer, worm reducer and no JWB-X series CVT, JWB-X continuously variable transmission + WWJ rod reducer, multi-functional polyhedron hardened surface combination, DMB series CVT and WJ series of screw Reducer PC Helical Gearbox, ring cone differential planetary transmission and cycloid reducer combination.
Applications: worm gear speed reducer is widely used in metallurgy, mining, lifting, transportation, cement, construction, chemical, textile, printing and dyeing, pharmaceutical and other fields.

What is the transmission reducer

The helical worm gearmotor is a power transmission mechanism which uses a gear speed converter to decelerate the number of revolutions of the motor to the desired number of revolutions and obtain a larger torque. The transmission reducer is a relatively sophisticated machine that uses its purpose to reduce the speed and increase the torque.
Transmission reducer type Hypoid Reducer, with transmission reducer, unilateral double drive reducer, harmonic transmission reducer, the central transmission reducer, edge drive Bevel helical gearbox and so on.
The mechanical variable speed gearbox has the characteristics of large transmission ratio, wide range, high precision, small back load, large carrying capacity, high efficiency, small volume, light weight, smooth transmission, low noise, transmission to the sealed space, etc. It is widely used In the space technology, energy, electronics industry, petrochemical, military industry, robots, instrumentation, textile machinery, printing machinery, packaging machinery, lifting transport machinery, medical equipment, food processing machinery and other industries.

The typical structure of the cycloidal planetary reducer, which consists mainly of four parts:

(1) The planetary frame consists of an input shaft and a double eccentric sleeve, and the eccentric sets of eccentric sets are 180 degrees.
(2) planetary wheel, also known as cycloid, the tooth profile is usually short outside the Cycloidal reducers of the inside of the equidistant curve. According to the requirements of the movement, a planetary wheel can be driven, but in order to make the input shaft to achieve static balance and improve the carrying capacity, for a tooth difference pin pendulum drive, often with two identical odd teeth of the planetary wheel Transmission is not subject to this limit), installed in the double eccentric sets, two rounds of position just 180 degrees difference. A roller bearing (called a boom bearing) is fitted between the planetary wheel (cycloidal wheel) and the eccentric sleeve to reduce friction. In order to save radial space, rolling bearings usually use roller bearings that do not have outer race The pinhole surface of the variable gear motor is directly used as a raceway. In recent years, the structure of the optimized design of the double eccentric sleeve and the bearing made of a whole, said the overall double eccentric bearing.
(3) Central wheel, also known as hypoid gearbox wheel, needle shell with a set of needle pin, usually pin pin is also equipped with needle sets.
(4) Output mechanism This is often used pin-type output mechanism.
