Metal gear grease: requires high lubricity, high adhesion, durability and other properties. It is recommended to use gear grease produced with synthetic base oil. The oil film is uniform and stable, and the durability is much better than mineral oil.
For all-metal gears, you can choose lubricating grease with higher viscosity, the oil film thickness will be thicker, and choosing the right viscosity will fill it better.
Plastic gear grease: The outstanding feature is that it has almost no chemical and physical reaction with plastics, so there must be necessary plastic compatibility test data, which is a basic performance requirement.
Since plastic gears have certain compatibility issues with grease, good plastic gear grease must be specially formulated for plastic products and use base oil with relatively high compatibility.
Since plastic gears have certain compatibility issues with grease, good plastic gear grease must be specially formulated for plastic products and use base oil with relatively high compatibility.
When selecting grease, you need to consider several standards:
① The working temperature can be divided into three states: high temperature, low temperature and normal temperature;
② Adhesion When the gear rotates, it has a centrifugal effect on the grease, and the size of the gear speed is proportional to the adhesion of the grease;
③ Load involves the selection of starting torque and anti-wear additives;
④ Low noise requirements;
⑤ Plastic material compatibility requirements;
⑥ Waterproof requirements;
⑦ Environmental protection requirements;
⑧ Design life of lubricated parts.
