Abstract
The utility model relates to a soft supporting sliding bearing. The radial position between the bearing and the supporting surface of the main axis is provided with a space for the heat inflation and the springy transformation. The space for the heat inflation and the springy transformation caused by the friction of the bearing extends outwards to ensure the smallest clearance between the main axis and the bearing. The utility model enhances the active effect of the centering precision, the operating precision and the vibrating proof function of the main axis.
Description
Technical field: the utility model provides a kind of flexible support sliding bearing.
Background technique: at present, machine tool chief axis adopts sliding bearing to support always.Because of between the bearing support of sliding bearing and bearing outside fixedly being belongs to the rigidity supporting.When producing thermal expansion and resiliently deformable because of rubbing at main shaft rotation process middle (center) bearing, easily cause the seize stuck phenomenon, limited the raising of lathe high-precision rotary and machining accuracy.
Summary of the invention: the purpose of this utility model provides a kind of flexible support sliding bearing that the lathe highi degree of accuracy turns round, resistance to shock is strong, stable cutting efficient is high that makes.
Technical solution of the present utility model is: a kind of Flexible Sliding bearing, comprise bearing support and the overcoat of being with oil film wedge, and it is characterized in that: thermal expansion amount that in the radial position of bearing and main shaft support face, is provided with and resiliently deformable leeway.
The utility model is that thermal expansion amount and the resiliently deformable leeway in the supporting surface radial position is provided in a side of on the bearing support.
Thermal expansion amount and the resiliently deformable leeway of the utility model in the supporting surface radial position puts outside can also being provided in a side of.
Owing to adopt said structure, the leeway that thermal expansion amount that bearing produces because of rubbing and elastic deformation amount radially are provided with stretches out, thereby has guaranteed the minimal gaps between main shaft and bearing, has improved centering precision, running accuracy and the resistance to shock of main shaft.
Description of drawings: the technical solution of the utility model is described further below in conjunction with the drawings and specific embodiments.
Fig. 1 is the utility model embodiment 1 a structural representation.
Fig. 2 is the A---A sound view of Fig. 1.
Fig. 3 is the utility model embodiment 2 a structural representation.
Tool example embodiment: embodiment 1.With reference to figure 1, Fig. 2.On sleeve type bearing body 1, be provided with oil film wedge 4; Outside bearing support 1, be provided with thermal expansion amount and resiliently deformable leeway 3 on the garden with on three supporting surface corresponding positions of main shaft; Overcoat 2 fixed covers are loaded on the bearing support 1.
Embodiment 2.With reference to figure 3.Itself and embodiment's 1 difference is that its thermal expansion amount and resiliently deformable leeway 3 are provided in a side of on the overcoat 2.
Thermal expansion amount described in the utility model and resiliently deformable leeway can be designed to shapes such as blade type, honeycomb.
