Planetary roller screw is a transmission component that converts rotational motion into linear motion. It has the advantages of high running speed, strong load-bearing capacity, good environmental adaptability and long service life, and has broad application prospects. The structure of the planetary roller screw is similar to that of the ball screw. The difference is that the load transmission element of the planetary roller screw is a threaded roller, which is a typical line contact.;The ball screw load transmission element is a ball, which is a point contact. The main advantage is the numerous contact points to support the load. Threaded rollers instead of balls will allow the load to be released quickly through numerous contact points, resulting in higher impact resistance. Folding load capacity life。
Regarding the lubrication of planetary roller screws, it is necessary to make a key introduction here, because good lubrication can ensure the service life of the screw and customer experience.Bisanu LubricationThe team has many years of experience inPlanetary screwFriction and lubrication technologyexperience,can be very goodSolve the lubrication problem of precision planetary roller screws,Since the threaded rollers of the planetary roller screw have many close contact lines, the friction coefficient of the grease must be low to ensure high accuracy during frequent reversals. Under a certain load, when the oil film is sufficient, it must also have a certain cooling effect.Successfully solved the heating problem of planetary roller screw during high-speed rotation.Planetary roller screw greaseIt uses high-quality, low-viscosity, high-performance synthetic base oil and is precisely produced through special processes. It is a relatively maturePlanetary roller screwgrease, andHas ultra-low friction coefficient,It can provide unparalleled shear stability; the special structure improver ensures low diffusion of grease and does not contaminate other parts; the structure is stable, the viscosity does not change much with temperature, and can provide stable torque, specifically solving the vibration problem of the planetary roller screw and ensuring the smoothness of the transmission motion of the planetary roller screw.
adoptgreaseThere are generally two ways to add oil during lubrication:
1, If the nut does not have a dust ring, just apply grease directly to the screw rod.
2Nuts with dust rings usually have oil holes and grease nipples on the nut. Just use a grease gun to drive grease into the nut.
Things to note when applying grease:
1, Please confirm the lubrication status before use. If the lubrication is not good, the function of the ball screw will be lost in a short period of time.
2, when coated with grease, please use it directly. However, during use, if dust or powder adheres to the surface of the grease, please wash it off with clean white kerosene, and then re-apply new grease that is the same as the original grease before use. The mixed use of greases of different properties should be avoided.
3, asgreaseinspection for putting into use2~3Months, when it is found that the dirt is obvious, it is recommended to wipe off the old lubricant on the product and re-apply new lubricant. After that, check the grease and replace the lubricant regularly. Under normal circumstances,1years, but please set the appropriate interval and grease replacement time according to the use environment.
