Gear Grease Series For Plastic Gears, Metal Gears

Gear grease is often used for the lubrication of plastic gears, metal gears (spur gears, helical gears, worm gears, helical bevel gears or staggered shaft gears), sliding parts, metal parts of electronic components, etc. Gear transmission pairs have different requirements for grease due to different materials, different sizes, different speeds, different gear shapes, different precision and many other factors.

product details

VNOVO developed gear lubricating greases with various functions and different viscosities,which can support various structural designs and material requirements, and can also meet the requirements of products in terms of high speed, high and low temperature, low current, noise reduction, damping, sealing, water resistance, corrosion resistance, etc;Compatible with most plastics and metals; With high adhesion, can effectively reduce the noise generated when the gear is running,anti-wear, anti-oxidation and long-lasting lubricating properties,complies with EU environmental requirements and is suitable for lifetime lubrication of products.

Plastic gears are the key basic components of mechanical equipment products.Plastic and composite gears can replace non-ferrous metal or alloy gears in many cases because of their advantages of light weight, low price, low transmission noise, fewer production processes, and at the same time the strength is close to that of metal gears,and widely used in industrial manufacturing, such as auto parts, instrumentation, digital electronics, household appliances, toys, energy, transportation and aviation and other fields.In order to ensure the correct lubrication of the gear parts of the equipment, it is necessary to know the operating conditions of the equipment in detail (including operating temperature, load, operating speed, structure, material, surrounding environment, etc) to facilitate the selection of the type of lubricating grease ,and meet the lifetime lubrication requirements of the product.

There are several criteria to consider when choosing the plastic gear grease:

1. When plastic gear grease is used for assembly type products, it is impossible to add and maintain in the middle.It needs to meet the lifetime lubrication and the long life of gears.

2. Good compatibility with plastics. because there are many types of plastic parts materials, it must be required that the assembly type grease must not have volume expansion, shrinkage, cracking, and mechanical properties decline with the plastic parts;

3. Suitable viscosity. Strong adhesion, thick oil film, can reduce noise and improve comfort.

4. can meet the high low temperature requirements of the product, the starting and running torque is small, and it has no effect on the current.

5. Low-odor, light-colored grease prevents pollution and meets EU environmental requirements.

In the metal pinion transmission mechanism, these metal pinion transmission pairs have different requirements for grease due to different materials, different sizes, different speeds, different gear shapes, different precision and many other factors.There are several criteria to consider when selecting the metal gear grease:

1. Wear resistance, low friction coefficient, prevent gear surface wear, ensure high efficiency and long life of gears

2. Good adhesion.Due to the grease rejection caused by the centrifugal force generated by the high-speed rotation of the gear, the grease must have good adhesion to the metal, and can form a high-adhesion oil film on the gear tooth surface, while effectively suppressing noise.

3. Good mechanical stability. When the gear is running, the grease will be sheared, which will cause the mechanical disintegration of the soap dispenser structure of the grease, and the grease will become soft and thin and will be lost, resulting in no oil film on the tooth surface, generating noise, and temperature rise, thus losing the lubricating effect;

4. Select temperature base oil and thickener according to the requirements of the operating environment.Fully synthetic base oil can reduce starting and running torque in cold environments without affecting motor temperature rise and current;Choosing the high dropping point thickeners,such as polyurea, lithium complex, can better meet the high temperature resistance requirements of metal gears.

5. Excellent compatibility: anti-corrosion, anti-rust effect, good compatibility with most of metals, plastics and rubber and contacting media.

Noise is often generated when two materials rub and slide against each other at high speed.Friction and stick-slip can be reduced or prevented by using suitable lubricants.Some rotating speed is as high as more than 10,000r/min, which brings a serious test to metal materials and plastic materials with poor geometric accuracy, soft materials and non-wear-resistant.There are several criteria to consider when selecting the high speed gear grease:

1. Select the appropriate base oil viscosity according to the gearbox structure, material and rotating speed.Balance starting, running torque, motor current and noise.

2. Thickener need to have good mechanical stability and adhesion.The choice of thickeners of lithium complex , lithium-based and calcium-based can effectively prevent the grease from softening, thinning and loss under the high-speed shearing of the gear, and meeting the requirement of lasting noise reduction.

3. Strong bearing capacity, additives containing high-quality anti-wear and anti-load can reduce the softening and failure of grease caused by friction and heating.

4. can meet the high low temperature requirements of the product, the starting and running torque is small, and it has no effect on the current.

5.Anti-corrosion, anti-rust effect, good compatibility with most of metals, plastics and rubber and contacting media.

6. Meet environmental requirements.

Low temperature greases are a grease that retain their properties at low temperatures.With the continuous development of the industry, the environment where the products are located has also changed from normal temperature and pressure to high temperature, low temperature, high pressure, low speed, high speed and other complex environments.If the working environment temperature is low, conventional grease is prone to solidification and hardening,and increase the frictional resistance and increase the wear of the internal parts of the product.The low-temperature grease adopts low-viscosity fully synthetic base oil, starts at low temperature and has a small running torque, which can well solve the problems of solidification and hardening of general grease at low temperature, ensure that the product is well lubricated and protected at the start-up stage, and reduce wear of parts and improved operational performance, giving products more stable, longer-lasting protection.
