For oil lubrication, the sealing mode of filling lubricating grease into the sealed guide rail in advance, and the filling and supplying mode of filling and supplying grease with proper amount of lubricating grease inside the shell and replenishing or replacing at intervals.
In addition, the centralized grease supply mode of pipeline connection to each lubrication point is also adopted for the machinery with multiple sliding rails to be lubricated. Grease lubrication can be achieved after a long time of filling the lubricating grease, and the structure of its sealing device is simple, so it is widely used. Oil lubrication is relatively simple, regular lubrication can greatly improve the service life of linear guide and maintain a certain accuracy and preloading.
1. Considering the friction affordable loading. The square meter is the contact friction of the square linear guide surface. The friction is large. Uniform load. Regular oil lubrication is required, but the circular guide is a cylindrical linear guide.
The friction is small. Because it's a series of point contact ball bearings. Support is limited. The rigidity difference load performance is limited. Only the radial load has good bearing capacity and the axial load is very small. Therefore, it has the advantages of high speed and square guide rail.
2. The function positioning accuracy of Shangyin linear guide is high. The friction coefficient is small. In particular, the difference between static friction and friction is very small. Even if there is no idle slippage. Analytical ability and best reproducibility.
Therefore, it can be realized that the woodworking engraving machine can maintain the positioning accuracy of the precise linear guide rail rolling friction μ m level for a long time. Low friction resistance, easy lubrication, can reduce the sliding resistance of guide rail by 1 / 20 ~ 1 / 40, especially the lubrication structure is simple. The friction contact surface has the lowest wear and good sliding effect. The walking accuracy can be maintained for a long time.
