Problems solved by technology

Electric spindles generally use bearings as the main shaft support. At this stage, ordinary deep groove ball bearings used in woodworking motors cannot meet the above-mentioned high-speed and precision requirements.
For the high-speed operation of the spindle, the ordinary sealing structure cannot well guarantee the dust-proof requirements of the electric spindle

Embodiment Construction

[0011] It can be seen from Figure 1 that the high-speed woodworking electric spindle includes a spindle, a stator and a rotor. Two front angular contact ball bearings 3, 6 are provided at the front shaft extension of the spindle, and an inner partition is provided in the middle of the two front angular contact ball bearings 3, 6 Ring 4 and outer spacer ring 5, the rear shaft extension end of the main shaft is provided with two rear angular contact ball bearings 7, 10, and an inner spacer ring 8 and an outer spacer ring 9 are arranged between the two rear angular contact ball bearings 7, 10. In order to meet the high-speed requirements of high-speed woodworking electric spindles and the high precision of the spindle shaft extension, high-precision angular contact ball bearings are used in the bearing structure design. The high-precision angular contact ball bearings have high precision and high limit speed, which can meet the requirements of high-speed woodworking electrical The sp...

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 [0001] The invention relates to an electric spindle technology, in particular to a woodworking electric spindle with high precision and high rotational speed. Background technique [0002] High-speed woodworking electric spindle is a high-tech mechatronics product, mainly used in wood processing industry. After years of development and changes in demand for wood products, the wood processing industry will inevitably encounter high-speed and precision machining problems during the machining process. Due to high-speed machining, the dust-proof technology of electric spindles also has high requirements. Electric spindles generally use bearings as spindle supports. At this stage, ordinary deep groove ball bearings used in woodworking motors cannot meet the above-mentioned high-speed and precision requirements. For the high-speed operation of the spindle, the ordinary sealing structure cannot guarantee the dustproof requirements of the electric spindle. Summary of the...
