Abstract
The invention discloses an environment-friendly high-speed motor spindle with a self-airtight-seal function. The environment-friendly high-speed motor spindle comprises a shaft shell and a spindle body installed in the shaft shell. The two ends of the spindle body are sleeved with bearings respectively. A rotor is arranged in the middle of the spindle body in a sleeving mode. The two ends of the rotor are sleeved with two balance disks respectively. A stator corresponding to the rotor is also arranged in the shaft shell. The two ends of the spindle body are supported by ceramic bearings. The spindle body is hollow, cooling liquid enters the hollow spindle body from a shaft shell hole, and labyrinth-shaped cooling water troughs are formed in the outer walls of the ceramic bearings. The environment-friendly high-speed motor spindle has the advantages of being simple in overall structure and long in service life and reducing the harm to the environment and workers.
Description
Technical field
The present invention relates to electro spindle technical field, be specifically related to autonomous air impervious environment-friendly type high-speed electric main shaft.
Background technology
High-sp eed spindle unit is the most key parts of high-speed processing machine tool.The type of High-sp eed spindle unit mainly contains electro spindle, pneumatic main shaft, hydrodynamic(al) main shaft.Dissimilar power output difference is comparatively large, and high-speed processing machine tool main shaft need realize lifting speed within the extremely short time, and stops in the quick standard of assigned address.This just requires that main shaft has very high angular deceleration and angular acceleration.If by intermediate links such as belts, not only can skid at fast state, produce vibration and noise, and increase rotary inertia, stop causing very large difficulty to the quick standard of lathe.At present, most high-speed machine tool main shaft adopts the main axle unit of built-in type spindle motor integration, i.e. so-called built-in electric motor main shaft (Build-inMotorSpindle), is called for short " electro spindle ".It adopts frameless motor, motor stator with coolant jacket is assemblied in the housing of spindle motor unit, the rotary part of rotor and machine tool chief axis is made of one, and the slewing range of main shaft is controlled by frequency-conversion alternating current motor completely, and variable-frequency motor and machine tool chief axis are united two into one.
Existing electro spindle generally adopts oils to lubricate, and its main cause is this electro spindle all dress steel ball bearings, and its produced heat that runs up all is distributed naturally by compressed air source.But its disadvantage is many.1, the air compressor machine that power consumption is large need be increased.2, secondary-atomizing system need be increased.3, discarded have several large pollution to surrounding enviroment.4, the potential safety hazard brought for mist of oil and enterprise employee health.
