What is the lubrication cycle for chain-driven electric pallet tilters?

2025-09-03 11:58:54

The lubrication cycle of the electric tray flipping machine with chain drive is not a fixed value, and the core depends on three key factors: frequency of use, load intensity, and environmental dust/humidity. It needs to be flexibly adjusted according to actual working conditions. The following are general lubrication cycle standards and optimization suggestions for different scenarios, which can cover the vast majority of industrial application scenarios:

Basic lubrication cycle: divided by "frequency of use+load".

The influence of environmental factors on lubrication cycle

The above basic cycle needs to be adjusted in conjunction with environmental conditions. Adverse environments can accelerate grease failure, so the lubrication interval needs to be shortened. The specific adjustment rules are as follows:

Dust/particle environment

Dust easily mixes with oil to form "sludge", blocking the gaps between chain links and exacerbating friction. Therefore, the basic cycle needs to be shortened by 30% -50%;

Before lubrication, it is necessary to clean the dust on the surface of the chain with compressed air or a brush, and then inject new oil to prevent the residue of old oil sludge.

High humidity/humid environment

Moisture can easily cause rusting of chains, emulsification and deterioration of grease. It is necessary to shorten the basic cycle by 20% -30% and prioritize the use of rust proof chain lubricants;

If there is condensation in the environment, it is necessary to check whether there is water accumulation at the joint of the chain link after each lubrication, wipe it dry in a timely manner, and apply a small amount of lubricating oil.

high temperature environment

High temperature can accelerate the evaporation and oxidation of lubricating oil, leading to oil film failure. It is necessary to shorten the basic cycle by 40% -60% and choose high-temperature chain oil to avoid oil carbonization and agglomeration at high temperatures.

Special circumstances: Scenarios that do not require strict periodic lubrication and require "immediate lubrication"

When the following signals appear, regardless of whether the cycle is reached, it is necessary to immediately stop the machine for inspection and supplement lubrication to avoid chain damage:

There is a "squeaking" dry friction sound when the chain is running;

Visually observe the disappearance of oil film and the appearance of dry rust on the surface of the chain;

After maintenance, the newly installed/adjusted parts of the equipment need to be re lubricated;

If the continuous operation time exceeds 12 hours, an additional lubrication should be added after the operation is completed.

Suggestions for optimizing lubrication cycle

Record "lubrication log": Record the date, operating conditions, and lubrication amount for each lubrication, and find the most suitable cycle for your own equipment through 1-2 months of data accumulation.

Avoid "excessive lubrication": too much grease will adsorb more dust, form sludge, and accelerate wear. Normal lubrication should have a "uniform thin oil film on the chain rollers and hinges, without obvious grease dripping".

Seasonal adjustment: In winter, when the temperature is low, the viscosity of lubricating oil increases and the fluidity is poor. It is advisable to increase the lubrication frequency appropriately or choose lubricating oil with good low-temperature fluidity to avoid chain links from getting stuck due to grease solidification.

Through the above layered adjustments, it is possible to ensure that the chain is always in an effective lubrication state, while avoiding losses caused by insufficient or excessive lubrication, and maximizing the service life of the chain and sprocket.

Is it necessary to shorten the lubrication cycle of the electric tray flipping machine with chain drive when used in environments with high humidity?

The lubrication cycle of the chain driven electric tray flipping machine must be shortened when used in environments with high humidity. High humidity environments can accelerate the failure of chain lubrication and cause metal corrosion. If lubrication is still carried out according to regular cycles, it can easily lead to increased chain wear, jamming, or even breakage. The specific reasons and adjustment plans are as follows:

The core reason for shortening the lubrication cycle in humid environments

Lubricating oil emulsifies and deteriorates, losing its lubricating effect

Water vapor in high humidity environments can seep into the hinge joints of chain links and mix with lubricating oil to form an "emulsion" - the original oil film is destroyed, the lubrication performance is greatly reduced, and the metal parts of the chain come into direct contact and friction, accelerating the wear rate by 2-3 times.

Accelerate chain corrosion and exacerbate friction damage

Even if the lubricating oil is not completely emulsified, water vapor will still adhere to the surface of the chain, causing oxidation and corrosion. Rust will act like an "abrasive" and scrape the sprocket teeth and the interior of the chain links during chain transmission, further damaging the lubrication layer and forming a vicious cycle of "rust lubrication failure more severe wear".

Precautions for lubrication supplementation in humid environments

Prioritize the use of "rust proof chain lubricant"

Avoid using ordinary mineral oil and choose specialized chain oil containing "extreme pressure anti rust additives". This type of oil can form a water-resistant protective film on the metal surface of the chain, reducing direct contact with water vapor and delaying corrosion and emulsification.

Before lubrication, it is necessary to clean the water vapor and rust on the surface of the chain

Before each lubrication, wipe the condensed water on the surface of the chain with a dry cloth. If slight rust has appeared, use fine sandpaper to gently polish and remove rust, then use compressed air to blow away residual impurities, and finally inject new oil - to avoid mixing old rust with new oil and affecting the lubrication effect.

Focus on strengthening the lubrication of the "chain link hinge joint"

Water vapor is most likely to seep into the gap between the pin shaft and the sleeve. It is necessary to use a lubricating oil gun to accurately inject oil into the hinge joint to ensure that the oil fills the gap and forms an effective oil film; If conditions permit, a "chain injector" can be used to achieve uniform coverage of the entire chain and reduce omissions.

In summary, environments with high humidity can significantly weaken the effectiveness of lubricating oil and accelerate chain damage. Therefore, a combination of measures such as shortening the lubrication cycle, selecting rust proof oil, and pre cleaning must be taken to ensure stable chain transmission and avoid equipment failures.
