Abstract
The utility model relates to an upper bearing support structure of a high-speed electric spindle, in particular to a bearing support assembly for an air-floating high-speed electric spindle of a mechanical processing lathe. The inner wall of an axial through hole of a bearing body (1) is provided with at least one bearing bush. The upper bearing support structure utilizes a combination structure, thereby being easy to process and convenient to assemble and disassemble, preventing a central spindle and bearing from locking, having good vibration damping effect, and being high in radiation efficiency, long in service life and suitable for popularization and application.
Description
Technical field
The utility model relates to a kind of machining equipment, specifically a kind ofly is used for the bearing block assembly that the mechanical processing machine air floated high speed electric mandrel is used.
Background technology
In the prior art, the bearing block assembly that air floated high speed electric mandrel is used, structure is single, and locking phenomenon takes place in processing difficulties easily, loading and unloading inconvenience, heat-sinking capability is low, and Oscillation Amplitude is big, and service life is short, needs shortcomings such as frequent replacing.
Summary of the invention
The utility model relates to a kind of top chock structure of high-speed electric main shaft, and it uses fabricated structure, makes handling ease, and is easy to loading and unloading, good damping result, and radiating efficiency height, axle core and bearing can lockings, and long service life is convenient to promote and use.
The utility model technical solution is that the utility model is provided with at least one bearing shell 2 particularly in the inwall at the axial pass-through holes place of bearing body 1 on the basis of existing bearing body 1, throttling damping plug 3, passage 4, cannelure 5, screwed hole 6, power hole 7 and flat position 8.
Inwall at the axial pass-through holes place of described bearing body 1 is provided with two bearing shells 2.
The utility model operation principle is that this structure is packed into when mainly using in the body, feed gas by the body place and enter the flat position 8 of bearing block, be connected with upper and lower cannelure 5 owing to flat 8, gas flows a week along cannelure 5 circumferencial directions, enters each passage 4 and throttling damping plug 3, produces radial suspension force, make a core diameter to suspension, the axle core is in the suspended state like this, without any contact friction, has reduced friction loss and heating most possibly when a core is rotated; Advance when the rotation of axle core is unbalance, axle core and top chock friction even locking phenomenon, we design composite bearing shell 2 in bearing block at above defective, even friction locking phenomenon can not occur yet. design has screwed hole 6 at the bearing body place, when needs are dismantled, be screwed into screw from screwed hole and be convenient to dismounting; There is power hole 7 in the upper bearing (metal) body, and stator lead-out wire can lightly be installed.
Advantage of the present utility model is:
1, this structural behaviour is stable, and is reliable;
2, increase bearing shell and shaft bearing plate and be difficult for locking, bearing and axle core are improved service life, convenient disassembly, maintenance cost is low.
3, be convenient to remove and install, simple to operate.

The specific embodiment
Embodiment 1
According to Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, the utility model is on the basis of existing bearing body 1, throttling damping plug 3, passage 4, cannelure 5, screwed hole 6, power hole 7 and flat position 8, and the inwall at the axial pass-through holes place of bearing body 1 is provided with at least one bearing shell 2.
Identical with embodiment 1, the inwall that is the axial pass-through holes place of described bearing body 1 is provided with two bearing shells 2.
Claims (2)
1. the top chock structure of a high-speed electric main shaft, it has comprised bearing body (1), throttling damping plug (3), passage (4), cannelure (5), screwed hole (6), power hole (7) and flat position (8), it is characterized in that the inwall at the axial pass-through holes place of bearing body (1) is provided with at least one bearing shell (2).
2. the top chock structure of a kind of high-speed electric main shaft according to claim 1 is characterized in that the inwall at the axial pass-through holes place of bearing body (1) is provided with two bearing shells (2).
