What are the reasons that affect the efficiency of planetary reducer?
Latest company news about What are the reasons that affect the efficiency of planetary reducer?

 

Planetary reducer is a widely used reduction transmission equipment. It reduces the speed of the input shaft through the meshing of planetary gears, and at the same time increases the output torque. The reduction efficiency is higher than that of ordinary reducers.

At present, the following factors affecting the operating efficiency of planetary reducer have been summarized:

 

Thermal management:

  1. During the operation of the precision planetary reducer, its iron core is located in the alternating magnetic field, which will produce iron losses. After the winding is energized, it will produce copper losses, which will also be mixed with other losses. These will cause the reducer to malfunction. temperature rises. The reducer itself has a heat dissipation function. When the heat generation and heat dissipation are equal, it will be in a state of equilibrium. If the temperature suddenly rises to break this balance, the temperature will continue to rise, thus affecting the normal operation of the reducer.
  2. Temperature rise refers to the temperature difference between the precision planetary reducer and the environment. It is generally caused by the heat of the reducer. The temperature rise is an important indicator during the operation of the reducer. It can clearly know the degree of heat generated by the reducer. . During work, if the temperature of the reducer suddenly rises, it means that the reducer is faulty, the vent is blocked, or the reducer is overloaded.
  3. The operating temperature refers to the operating temperature of the precision planetary reducer during the expected design life. If the operating temperature exceeds the operating temperature for a long time, the aging of the insulating material will be accelerated, thereby greatly shortening the service life of the reducer. Therefore , During the operation of the reducer, temperature is one of the main factors that affects the service life of the reducer.

 

Energy loss:

  1. Gear set losses: Depending on the type of gear set, efficiency losses can have a minor or major impact. Spur, helical and bevel gear losses will fall from 0.5%-3%, while flank and bevel gear losses may be as high as 5%. Hyperboloids and planar surfaces will lose efficiency by 2%-10%. Gear sets that may exhibit higher efficiency losses include: crossed helical 5%–50%; cylindrical worm and high reduction hypoid 10%–50%; double-enveloping worm and helix 2%–50%; helical 3%– 50%.
  2. Seal loss: Seals are used to prevent lubricating oil from escaping from the inside of the planetary reducer and to prevent external ash layers from entering the reducer. The static seals used between the housing parts have no effect on the efficiency of the planetary reducer. Dynamic seals do affect efficiency, however, because they are in contact with a rotating component, usually a shaft. As the shaft rotates within the stationary seal, friction and heat reduce efficiency. To reduce the effects of friction, lubrication is provided between the shaft and seal. It is important to note that different seal types will exert different resistance on the shaft. For example, a double lip shaft seal will have a higher level of ingress protection but will exert more friction than a single lip seal. Applications using O-rings as rotary seals may experience greater losses than double-lip shaft seals.
  3. Bearing Loss: Bearings come in many different types and styles. Effective are roller bearings that do not contain seals. Many different kinds of seals can be added to roller bearings; doing so may add a level of drag that reduces the overall planetary reducer's efficiency. Many different types of bearing grease can also be used and may affect efficiency depending on the viscosity of the grease. Other slightly less efficient bearing types include: powdered metal bronze, iron bushings, and molded plastic bushings. Lubrication Planetary reducers are lubricated with grease or oil. There are many variations of greases and oils with properties such as: high temperature, low temperature, extreme pressure, water resistance, corrosion protection, etc.

 

Lubrication condition:

  1. One key factor that can affect the efficiency of a planetary reducer is the viscosity of the lubricant. As the lubrication becomes more viscous or "thicker" - due to a drop in temperature - more resistance is introduced within the planetary reducer, making it less efficient. The opposite is true when the temperature increases; the viscosity of the lubricant decreases and becomes "thinner", thereby increasing the efficiency of the planetary reducer. The lubricant fill or how much lubricant is added to the planetary reducer can also affect efficiency. Too much lubrication in a high-speed planetary reducer can cause a stirring action that generates excessive heat and efficiency losses; however, insufficient lubrication can cause excessive wear on the gear set.
