What oil should be added to the reduction gearbox: comprehensive analysis and practical guide

As the core component of mechanical equipment, the reduction gearbox has a direct impact on the life and operating efficiency of the equipment. This article combines the hot topics on the Internet in the past 10 days to provide you with detailed answers to the selection standards, common questions and precautions for gearbox oil.

1. Types and selection criteria of reduction gearbox oil

What oil should be added to the reduction gearbox?

There are many types of reduction gearbox oil, which need to be selected according to the equipment model, working environment and load conditions. The following are common types of reduction gearbox oil and their applicable scenarios:

Oil typeFeaturesApplicable scenarios
mineral oilLow cost, basic lubricityLow speed and light load equipment, such as small transmissions
synthetic oilStrong high temperature stability and long lifeHigh load, high temperature environment (such as metallurgical equipment)
Extreme pressure gear oilContains anti-wear additivesHeavy load, impact load (such as mining machinery)

2. Recent popular questions and answers

Based on the discussions on the entire network in the past 10 days, the following are the reduction gearbox lubrication issues that users are most concerned about:

1. How often should the gearbox oil be replaced?

Depending on the frequency of device use and environment, general recommendations are:

Working conditionsReplacement cycle
Normal working conditions (8 hours/day)6-12 months
High temperature/high dust environment3-6 months

2. Is it possible to mix different brands of oil?

Not recommended! Different brands of additives may undergo chemical reactions, resulting in reduced lubrication performance.

3. Precautions for refueling the reduction gearbox

  • Oil level check:The amount of oil needs to be 1/2~2/3 of the viewing window. Too much oil will cause heat generation, and too little oil will cause insufficient lubrication.
  • Cleanliness:Clean the oil port before refueling to prevent impurities from entering.
  • Temperature adaptation:Choose low-viscosity oil (such as ISO VG 68) for low-temperature environments, and high-viscosity oil (such as ISO VG 220) for high temperatures.

4. A hotly discussed case across the entire network: Equipment damage in a factory due to improper oil selection

A recent case came to light on a forum: The factory suffered gear pitting due to misuse of non-extreme pressure oil, and the repair cost exceeded 50,000 yuan. Expert advice:Be sure to consult the equipment manual or consult the manufacturer, avoid losing big for small things.

Summary

The correct selection and maintenance of reduction gearbox oil is the key to efficient operation of the equipment. Through the structured data and hot spot analysis in this article, I hope it can help you make scientific decisions. If you need further guidance, please contact a professional lubrication service provider.
