Abstract
The present invention relates to a kind of machine tool chief axis, and including main shaft body, which connect with a bearing；An at least elastic buffer structure is equipped between the front end of the main shaft body and the bearing, which is used for the buffering of main shaft body and bearing；An anti-wearing liner is arranged with outside the front end area of the main shaft body, the gap floated for main shaft body is equipped between the anti-wearing liner and main shaft body.Good reliability of the present invention, wear-resistant, service life is longer, and when replacement only needs to change bushing.
Description
Technical field
The invention belongs to machine component fields, and in particular to a kind of main shaft more particularly to a kind of machine tool chief axis.
Background technology
Machine tool chief axis refers to the axis that workpiece or cutter rotation are driven on lathe.Usually by main shaft, bearing and driving member（Tooth
Wheel or belt wheel）Deng composition spindle unit.It is mainly used to support driving parts such as gear, belt wheel in the machine, transmit movement and turns round
Square.
Main shaft of the prior art can cause to wear when working long hours, and also not have defencive function, so as to cause it
Service life is not grown, and is needed frequent integral replacing, is caused the wasting of resources.
It is therefore proposed that a kind of machine tool chief axis is the subject of the invention to be studied.
Invention content
The main purpose of the application is to provide a kind of machine tool chief axis, with overcome the prior art can wear, service life compared with
Short, the problems such as needing integral replacing when replacing.
To realize aforementioned application purpose, the technical solution that the application uses includes：A kind of machine tool chief axis, including main shaft sheet
Body, the main shaft body are connect with a bearing；
An at least elastic buffer structure is equipped between the front end of the main shaft body and the bearing, which is used for
The buffering of main shaft body and bearing；An anti-wearing liner is arranged with outside the front end area of the main shaft body, the anti-wearing liner and master
The gap floated for main shaft body is equipped between shaft body.
Further, the elastic buffer structure is a ring washer, the ring washer be located at main shaft body and bearing it
Between.
Further, the bearing includes bearing inner race, bearing outer ring and bearing roller.
Further, the ring shape that is sticked on the inner wall of the bearing inner race is expanded with heat and contract with cold structure, and the annular heat expansion is cold
The coefficient of thermal expansion of shrinking structure is more than the coefficient of thermal expansion of bearing inner race.
Further, the annular is expanded with heat and contract with cold between structure and bearing inner race using interference fit.
Further, the anti-wearing liner uses cermet composite bush.
Further, the main shaft body axially inside offers a straight slot.
By above technical solution, the advantageous effect of the application is：Good reliability of the present invention, it is wear-resistant, use the longevity
Life is longer, and when replacement only needs to change bushing.
With reference to following explanation and attached drawing, the particular implementation of the application is disclosed in detail, specifies the original of the application
Reason can be in a manner of adopted.It should be understood that presently filed embodiment is not so limited in range.In appended power
In the range of the spirit and terms of profit requirement, presently filed embodiment includes many changes, modifications and is equal.

Specific embodiment
Embodiment：A kind of machine tool chief axis
Referring to attached drawing 1, including main shaft body 1, which connect with a bearing 5.
An elastic buffer structure 3, the elastic buffer structure 3 are equipped between the front end of the main shaft body 1 and the bearing 5
For the buffering of main shaft body 1 and bearing 5.An anti-wearing liner 2 is arranged with outside the front end area of the main shaft body 1, this is wear-resisting
The gap floated for main shaft body is equipped between bushing 2 and main shaft body 1, anti-wearing liner 2 uses cermet composite bush.
In the present embodiment, the elastic buffer structure 3 is a ring washer, which is located at main shaft body 1 and axis
It holds between 5.The bearing 5 includes bearing inner race, bearing outer ring and bearing roller, is pasted on the inner wall of the bearing inner race
It expands with heat and contract with cold structure equipped with a ring shape, the expand with heat and contract with cold coefficient of thermal expansion of structure of the annular is more than the thermal expansion system of bearing inner race
Number, the annular are expanded with heat and contract with cold between structure and bearing inner race using interference fit.
In addition, the main shaft body 1 axially inside offers a straight slot 4, the straight slot is for injecting lubricating oil, use
It is better.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar can understand present disclosure and implement according to this, and it is not intended to limit the scope of the present invention.It is all according to the present invention
The equivalent change or modification that Spirit Essence is made, should be covered by the protection scope of the present invention.
