Abstract
The invention discloses a high speed electric main shaft used for carpentry, which comprises a main shaft, a stator and a rotor. The front extension end of the main shaft is provided with two front rake touch ball bearings (3, 6). An inner ring spacer (4) and an outer ring spacer (5) are arranged between the two front rake touch ball bearings (3, 6). The rear extension end of the main shaft is provided with two bottom rake touch ball bearings (7, 10). An inner ring spacer (8) and an outer ring spacer (9) are arranged between the two bottom rake touch ball bearings (7, 10). The utility model adopts the structure, and the extension ends of the main shaft can receive radial force, axial force and rigidity, the utility model can also be dustproof, and meets the requirement of present numerical control wood processors. Accordingly, the field of application of the high speed electric main shaft used for carpentry is widened; and the service life of the high speed electric main shaft used for carpentry is increased.
Description
Technical field
The present invention relates to a kind of electric spindle technology, especially relate to a kind of high accuracy that has, and can realize high-revolving woodworker power principle axis.
Background technology
High-speed woodworker power principle axis is the very high electromechanical integrated product of a kind of technology content, is mainly used in wooden processing industry.The wood processing industry, will inevitably run at a high speed and precision machined problem in the course of processing through the variation of years of development and wood products demand, owing to the reason of High-speed machining also has very high requirement to the dust control technology of electric main shaft.The electricity main shaft generally adopts bearing as main shaft supporting, and the common deep groove ball bearing that present stage carpenter motor uses can't satisfy the requirement of above-mentioned high speed, precision.For running up of main shaft, common hermetically-sealed construction can not well guarantee the dustproof requirement of electric main shaft.
Summary of the invention
The purpose of this invention is to provide a kind of high-speed woodworker power principle axis, can satisfy the requirement of bearing radial force, axial force and rigidity simultaneously of main shaft shaft extension end, also can solve the dustproof problem.
The problem that will solve required for the present invention realizes by the following technical solutions: it comprises main shaft, stator and rotor, angular contact ball bearing before the preceding shaft extension end of main shaft is provided with two, be provided with cone spacer and outer ring spacer before two in the middle of the angular contact ball bearing, the back shaft extension end of main shaft is provided with two back angular contact ball bearings, is provided with cone spacer and outer ring spacer in the middle of the two back angular contact ball bearings.
Seal cover and protecgulum before the preceding shaft extension end of described main shaft is provided with, the cooperation place of preceding seal cover and protecgulum is provided with the labyrinth ring structure, seal cover and bonnet after the back shaft extension end of main shaft is provided with, the cooperation place of back seal cover and bonnet is provided with the labyrinth ring structure.
The place, Bearing Installation position of described main shaft is provided with the escape structure.
The said structure that the present invention adopts, owing to can satisfy the requirement of bearing radial force, axial force and rigidity simultaneously of main shaft shaft extension end, also can solve the dustproof problem, satisfied the requirement of present stage numerical control wood processing equipment, expand the range of application of high-speed woodworker power principle axis, also improved the useful life of high-speed woodworker power principle axis.
Description of drawings
The present invention is described further below in conjunction with accompanying drawing:
Figure 1 shows that structural representation of the present invention
Figure 2 shows that the partial enlarged drawing at K place among Fig. 1
Embodiment
As shown in Figure 1, this high-speed woodworker power principle axis comprises main shaft, stator and rotor, angular contact ball bearing 3,6 before the preceding shaft extension end of main shaft is provided with two, be provided with cone spacer 4 and outer ring spacer 5 before two in the middle of the angular contact ball bearing 3,6, the back shaft extension end of main shaft is provided with cone spacer 8 and outer ring spacer 9 in the middle of being provided with two back angular contact ball bearings, 7,10, two back angular contact ball bearings 7,10.For high speed, the high requirement of main shaft shaft extension end precision of satisfying high-speed woodworker power principle axis, in the bearing arrangement design, adopt the high accuracy angular contact ball bearing, the precision height of high accuracy angular contact ball bearing, limit speed height, the speed that can satisfy high-speed woodworker power principle axis reaches the requirement of 7000-24000r/min, also can satisfy the circular runout of main shaft shaft extension end, the requirement that end face run-out reaches 0.003mm.Preceding angular contact ball bearing 3,6 and back angular contact ball bearing 7,10 all adopt paired back-to-back installation pattern.The preload size of angular contact ball bearing and back angular contact ball bearing before adjusting with inside and outside spacer ring satisfies the requirement of bearing radial force and axial force, rigidity simultaneously of main shaft shaft extension end.The electricity main shaft can also directly be installed process tool at main shaft shaft extension end and process.
Seal cover 1 and protecgulum 2 before the preceding shaft extension end of main shaft is provided with, preceding seal cover 1 is sleeved on the main shaft, and cooperate installation with protecgulum 2, the cooperation place of preceding seal cover 1 and protecgulum 2 is processed with the labyrinth ring structure, back shaft extension end at main shaft is provided with back seal cover 12 and bonnet 11, back seal cover 12 is sleeved on the main shaft, and cooperates installation with bonnet 11, and the cooperation place of back seal cover 12 and bonnet 11 is processed with the labyrinth ring structure.Solve the dustproof problem of high-speed woodworker power principle axis with the structure of labyrinth ring.As seen from Figure 1, Figure 2, be processed with the escape structure, guarantee the installation quality of high accuracy angular contact ball bearing, thereby satisfy the shaft extension end precision height of high-speed woodworker power principle axis, the requirement that limit speed is high at the place, Bearing Installation position of main shaft.
