Abstract
The utility model relates to a linear bearing with a resistor. A linear bearing jacket is provided with an arc-shaped elastic steel ball guide rail and a steel ball and is assembled by penetrating through a guide column, and powder metallurgy oil-containing sleeves are fixed on both ends of the linear bearing jacket; the steel ball is pressed on the guide column through the elasticity of the arc-shaped elastic steel ball guide rail to form certain resistance, then the lubrication on the linear bearing is achieved by utilizing the viscosity of lubricating oil contained in the powder metallurgy oil-containing sleeves, the accuracy improving of a print member is realized by stabilizing the resistance of the linear bearing by utilizing the viscosity of the lubricating oil, and the accuracy can be ensured if the speed is relatively high.
Description
Technical field
The utility model is a kind of linear bearing with resistance gauge, belongs to field of mechanical technique.
Background technique
The quality that 3D prints depends on the repetitive positioning accuracy of X-axis and Y-axis, in resetting generally because linear bearing does not have resistance devices, print come and go in due to the existence of inertia, it was caused because of inertia in oppositely in moment, the micro-deformation of guide rail mechanism, make print member precise decreasing, and the faster precision distortion of speed is larger.
Summary of the invention
The purpose of this utility model is to provide a kind of linear bearing with resistance gauge, realizes the object that print member precision improves.
Its objective is such realization, a kind of linear bearing with resistance gauge is made up of guide pillar, power metallurgical oil-retaining cover, steel ball, arc elastic steel ball guide rail, linear bearing overcoat; Linear bearing overcoat is provided with arc elastic steel ball guide rail and steel ball, and through guide pillar assembling, is fixed with power metallurgical oil-retaining cover at the two ends of linear bearing overcoat.
Elastic force by arc elastic steel ball guide rail is pressed in steel ball on guide pillar, to form certain resistance, the toughness of lubricant oil in recycling power metallurgical oil-retaining cover, not only play lubricating linear bearing, and utilize its toughness to stablize its resistance, realized print member precision and improved, and the faster precision of speed can also obtain guarantee.
Accompanying drawing explanation
Concrete structure of the present utility model is provided by following examples and accompanying drawing:
Fig. 1, be a kind of linear bearing structural representation with resistance gauge of the utility model.
In Fig. 1,1, guide pillar, 2, power metallurgical oil-retaining cover, 3, steel ball, 4, arc elastic steel ball guide rail, 5, linear bearing overcoat.
Embodiment
Describe the specific works situation the utility model proposes in detail below in conjunction with Fig. 1, in Fig. 1
Elastic force by arc elastic steel ball guide rail 4 is pressed in steel ball 3 on guide pillar 1 and forms certain resistance, and the toughness of lubricant oil in recycling power metallurgical oil-retaining cover 2 not only plays lubricated to linear bearing, and utilizes its toughness to stablize its resistance.
