Lubricating oil selection for hardened bevel gear reducer

I. Introduction

With the continuous development of industry, hardened bevel gear reducer, as an important transmission device, is widely used in various mechanical systems.However, in order for the reducer to achieve optimal performance, the selection of lubricant is particularly important.This article will introduce in detail the lubricant selection for hardened bevel gear reducers.

2. Characteristics of hardened bevel gear reducer

The hardened bevel gear reducer has the characteristics of high transmission efficiency, strong load-bearing capacity and long service life.However, due to the large gear contact stress and the high friction coefficient of the gear friction pair, the requirements for lubricating oil are also high.

3. Basic knowledge of lubricants

Lubricating oil is a liquid that can reduce the friction coefficient of gears and can protect the gear surface and prevent oxidation and corrosion.The selection of lubricating oil should consider the following factors: viscosity, oxidation resistance, anti-wear, extreme pressure, etc.

4. Lubricant selection for hardened bevel gear reducer

1. Viscosity selection: Viscosity is an important indicator of the fluidity of lubricating oil.Choosing the appropriate viscosity can ensure the formation of a sufficient lubricating oil film on the gear contact surface, thereby reducing the gear friction coefficient and improving transmission efficiency.Generally speaking, hard-tooth surface bevel gear reducers need to choose high-viscosity lubricating oil to ensure the lubrication effect of the gear surface under high-speed and heavy-load conditions.

2. Oxidation resistance selection: The hard-tooth surface bevel gear reducer will generate a large amount of heat during operation. This heat will increase the temperature of the lubricating oil and accelerate its oxidation and deterioration.Therefore, choosing a lubricant with good oxidation resistance can extend the service life of the lubricant.

3. Anti-wear selection: Since the gear contact stress of the hard-toothed bevel gear reducer is large, it is necessary to select lubricating oil with good anti-wear properties.This can reduce the wear of the gear friction pair and extend the service life of the gear.

4. Extreme pressure selection: Extreme pressure refers to the ability of lubricating oil to maintain stability under high pressure and high temperature.Choosing lubricating oil with good extreme pressure properties can prevent the lubrication film from breaking under the high-pressure and high-temperature working conditions of the hard-tooth surface bevel gear reducer, thereby ensuring the lubrication effect of the gear surface.

5. Lubricating oil replacement cycle

In order to ensure the normal operation of the hardened bevel gear reducer, the lubricating oil needs to be replaced regularly.Generally speaking, the lubricating oil replacement cycle should follow the following principles:

1. Change the lubricating oil once a week after the first operation to remove impurities and dirt brought into the gearbox during new installation;

2. Check the cleanliness and viscosity of the lubricating oil every three months. If the lubricating oil is found to be deteriorated or contaminated, it should be replaced in time;

3. Replace the lubricating oil at least once a year to ensure the normal operation of the hardened bevel gear reducer.

6. Conclusion The selection of lubricant for the hardened bevel gear reducer is an important link to ensure its normal operation.Only by selecting the appropriate lubricating oil can the best performance of the hard-tooth surface bevel gear reducer be fully exerted.I hope this article will be helpful to readers when selecting and using hardened bevel gear reducers.
