Why Should The Speed Reducer Be Equipped With A Cooling Fan?

图片
We often see the installation of a cooling fan on the high-speed shaft of the geared motor. As we all know, the installation of a cooling fan is to enhance the cooling of the temperature of the geared motor. Thermal power refers to the actual power that does not exceed a certain calculated oil temperature during continuous operation of the gearbox. The heat treatment method of the gearbox is generally carburizing and quenching. When selecting a hard-tooth surface reducer, an important parameter is the thermal power. The thermal power of the reducer is closely related to its heat dissipation. To increase the thermal power, the heating problem in the box should be solved first. When the reducer is running due to excessive heat (heating and heat dissipation process), due to meshing loss, bearing loss, oil stirring loss, and sealing loss, a large amount of heat is generated, which causes the temperature of the reducer to rise due to excessive power loss, which limits the system The normal ...

What Are Common Problems And Solutions For Cycloidal Reducers?

图片
Cycloidal pinwheel reducer is a common equipment in the factory. Since it is a mechanical device, more or less mechanical problems will naturally occur. Let's introduce some common problems of cycloid pinwheel reducer. 1. Noise The most common fault of the cycloid reducer is noise, which is also the easiest problem to find. Generally speaking, if there is noise, it is likely to be poor gear meshing or corresponding damage. If there is a noise, you need to turn off the equipment immediately and disassemble it to check the condition of the relevant parts. If you leave it alone, it is prone to bigger problems. 2. The host is overheated The host is overheated. If the host is overheated, it is most likely due to overload or too little grease. At this time, we need to let the reducer take a break. If the operation still overheats after the break, it may be that the model does not match, and the model needs to be replaced. In addition, it is necessary to confirm the grease indicator line,...

How To Calculate Reduction Ratio And Torque?

图片
1. Definition of reduction ratio: The reducer is generally used for low-speed and high-torque transmission equipment. The motor, internal combustion engine or other high-speed running power is used to achieve the purpose of deceleration through the gear with a small number of teeth on the input shaft of the reducer and the large gear on the output shaft. The reducer will also have several pairs of gears with the same principle to achieve the ideal reduction effect. The ratio of the number of teeth of the large and small gears is the reduction ratio, also called the transmission ratio (referred to as ""speed ratio""). 2. Calculation method of reduction ratio 1. Define the calculation method: reduction ratio = input speed ÷ output speed. 2. General calculation method: reduction ratio = operating torque ÷ 9550 ÷ motor power × motor power input revolutions ÷ use coefficient. 3. Gear system calculation method: reduction ratio = number of driven gear teeth ÷ number of dri...

What Are The Matters Needing Attention When Installing Reducer Coupling?

图片
When installing the reducer, it is necessary to install a coupling. The installation of the coupling is very important. If the coupling is not installed properly, it will cause problems such as broken shaft of the reducer, which will bring unnecessary trouble to the user. How to install the coupling of the reducer? What should I pay attention to when installing?  Here is an introduction for everyone: If you purchase a coupling by yourself, please pay special attention to the following dynamic/static balance requirements for the coupling, otherwise the coupling will generate additional radial and axial forces on the reducer shaft and bearings, and accidentally damage the reducer . When the peripheral speed of the outer diameter of the coupling is 30m/s and below, it must be statically balanced; when the peripheral speed of the outer diameter of the coupling exceeds 30m/s, it must be dynamically balanced. If the coupling needs to be pre-heated during installation, it is recommended t...

Why Does The Reducer Use Oil?

图片
With the rise of tribology in the 1860s, an organic connection was established between friction, wear, lubrication, and part design. 1. Wear Initial wear stage – Due to manufacturing and installation reasons, the initial wear of the parts is relatively fast, so the first oil change time is short Stable wear stage – The wear rate is slow and constant, usually the length of the mechanical life refers to this period of time Accelerated wear stage – Decrease in mechanical efficiency, change in gap and shape, generate noise and vibration, and must be repaired or replaced 2. Lubrication The lubrication mechanism of gear transmission is to allow lubricant to enter the meshing gear surface, forming a lubricating film to force the meshing tooth surfaces to separate, and turning the dry friction of the meshing tooth surface into internal friction between the internal molecules of the lubricant. Reduce friction Avoid direct contact between metal and metal, turning dry friction into fluid friction...

How To Replace The Bearings Of The Reducer?

图片
There are many types of reducers. According to the type of transmission, it can be divided into cycloid reducer, gear reducer, worm reducer and planetary gear reducer. Reducers usually use tapered bearings and deep groove ball bearings. So how to correctly replace the reducer bearing in use? 1. If the reducer is running and the bearing is in an abnormally high position, stop the machine and check whether the bearing is damaged. If it is damaged, it should be replaced immediately, and the transmission will not fail to prevent damage to other parts and reduce productivity. 2. When the reducer is running, the bearing position produces noise. Stop the equipment at this time and check whether the bearings are damaged. If damaged, it should be replaced immediately. In this case, consider whether the noise is caused by the bearing or gear meshing. 3. If there is no oil in the reducer, it is forbidden to run. Using proper lubricating oil, during the operation of the reducer, a very thin protec...

What Are The Reasons For The Bearing Damage Of The Reducer?

图片
1. The bearing cavity is not cleaned or the grease added is not clean. For example, the tiny rigid material in the bearing cage is not completely cleaned up, and the bearing raceway is damaged during operation, causing excessive temperature rise to burn the bearing. Solution The gearbox cleaning and maintenance machine uses the original lubricating oil of the gearbox to clean the gearbox without adding any cleaning agent, which will not cause secondary pollution to the gear; the filtered oil can also be used again in low-end occasions to achieve Resource reuse. 2.Due to the excessively high operating temperature of the motor body and the lack of oil in the bearing and the lack of grease in the bearing in time, the bearing may even be burned. 3. Improper assembly of the bearing, such as unevenly knocking the inner ring of the bearing during cold assembly to cause the shaft to wear out, causing the inner ring of the bearing and the bearing to lose or reduce the amount of interference, an...

What Are The Common Treatment Methods For Reducer Noise?

The reason why the reducer produces noise is mainly due to the friction, vibration and collision of the transmission gear. How to effectively reduce and reduce the noise and make the reducer more in line with environmental protection requirements is also a key research topic at home and abroad. Reducing the gear transmission noise during the operation of the reducer has become an important research topic in the industry. Many scholars at home and abroad regard the change of gear tooth meshing stiffness in gear transmission as the main factor of gear dynamic load, vibration and noise. Use the method of shape modification to minimize the dynamic load and speed fluctuation to achieve the purpose of reducing noise. This method has proved to be a more effective method in practice. However, with this method, the process requires shaping equipment, which is often impossible for the majority of small and medium-sized factories. After years of research, some scholars have proposed that by optim...

What Are The Reasons And Countermeasures For The Oil Leakage Of The Reducer?

图片
Reason analysis:   There are many ways of oil leakage in the reducer, but the most common one is the oil leakage at the seals of the driving and driven shaft heads, especially the oil leakage at the sealing ring of the driving shaft. In addition to the above cases, there are the following 3 oil leakage locations.   a. Oil leakage along the box surface of the reducer; b. Oil leakage along the sight hole cover above the reducer; c. Oil leakage along the oil drain hole at the bottom of the reducer;   Oil leakage at the sight hole cover and the oil drain hole is mainly caused by the fixing bolts are not fully tightened or the sealing gasket is not installed. When assembling the box for individual reducers, there are iron filings on the box surface, which makes the box surface not tight and leaks oil. In addition to the above-mentioned factors, the reason for oil leakage on the sealing surface is that the housing of the reducer is deformed after a period of use, causing the se...

What Are The Causes And Solutions Of Reducer Fever?

图片
When the reducer is in normal operation, due to the loss of efficiency, part of the input power will be converted into heat energy, making the internal temperature of the reducer rise, if the temperature is too high, it will cause damage to the internal parts. Therefore, the pre-selection and checking of reducer should meet the requirements of thermal power. Cause of reducer fever: 1. Possible causes: reducer overload operation, bearing wear, improper assembly of bearings, gears, shafts and other parts, too high or too low voltage, too much start and stop in a short time, poor lubrication, etc. 2.
