The material selection

The worm gear reducer is not well prepared in processing technology and material, it can cause the transmission failure. Worm gear speed reducer is also the problem that the gear reducer may encounter when making parts, such as the hardness of the hard surface speed reducer, and the unreasonable design of the screw lift bearing design.
Due to large worm drive meshing friction, worm gear hob is difficult to accurately backoff size and shape error. As a result of that the worm gear tooth surface is very difficult to work out and the worm tooth surface match completely to meet the requirements of the theory of conjugate condition. Therefore, the worm and worm gear tooth should have both wear resistance and good running performance.
Worm materials generally made of alloy steel or high quality carbon steel, and worm gear tooth surface by carburizing, quenching and nitriding heat treatment and high hardness, its hardness is between 35-55 HRC in general, but also has more than 60 HRC.
The materials used in worm gear ring are the most ideal for tin bronze, and the mechanical properties of centrifugal casting are the best in the process, followed by casting of metal mould, the most of which is not cast in sand mold.

Considerations

The worm gear reducer shall not be damaged by gravity hammer and reducer. Worm gear speed reducer is normal to overhaul the installation foundation, sealing parts and transmission gearbox. If normal use, the highest temperature of the lubricating oil should be less than 85 ℃. If the oil temperature rise and change abnormal, produce abnormal noise and so on, must stop immediately check, after troubleshooting, can continue to use.

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.

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.
