Abstract
The utility model relates to accessories of a machine tool, and discloses a main shaft of the machine tool. The main shaft of the machine tool comprises a main central spindle, bearings and a bearing sleeve. At least three bearings are uniformly arranged between the interior of bearing sleeve and the main central spindle, respectively. The main central spindle is ladder-shaped. The bearings are arranged from one side to the other side in a sequential enlarging manner. The main shaft has the advantages of strong bearing capacity, no need of frequent maintenance and reduction of production cost.
Description
Technical field
The utility model relates to machine tool accessories, specifically relates to a kind of main shaft.
Background technology
Machine tool chief axis refers to the axle that drives workpiece or cutter rotation on the lathe; Usually by main shaft core, bearing and and axle sleeve form, in the prior art, just be provided with bearing at the two ends of axle sleeve; The intensity that such main shaft has tolerance is not high; The shortcoming of damaging easily needs often maintenance, has increased production cost.
Summary of the invention
The purpose of the utility model is exactly to above-mentioned shortcoming, the machine tool chief axis that provides a kind of ability to bear by force, not need frequent maintenance, reduce production costs.
The technical scheme of the utility model is achieved in that a kind of main shaft of lathe, comprises main shaft core, bearing and axle sleeve, it is characterized in that: three bearings are arranged at least respectively between axle sleeve inside and main shaft core uniformly.
Say that further described main shaft core becomes notch cuttype, described bearing increases setting successively from a side to opposite side.
The beneficial effect of the utility model is: such main shaft has the advantage that ability to bear by force, does not need frequent maintenance, reduces production costs.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model main shaft.
Wherein: 1, main shaft core 2, bearing 3, axle sleeve.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, a kind of main shaft of lathe, comprise main shaft core 1, bearing 2 and and axle sleeve 3, it is characterized in that: three bearings are arranged at least respectively between axle sleeve 3 inside and main shaft core 1 uniformly.
Further say, 1 one-tenth notch cuttype of described main shaft core, described bearing 2 increases setting successively from a side to opposite side.
Claims (2)
1. the main shaft of a lathe comprises main shaft core, bearing and axle sleeve, it is characterized in that: three bearings are arranged at least respectively between axle sleeve inside and main shaft core uniformly.
