Abstract
The invention relates to an internal shaft oil supply-type rotating shaft, and relates to the field of machine tool equipment. The inner shaft oil supply-type shaft comprises an outer shaft, an inner shaft and a ball. The ball is arranged between the inner shaft and the outer shaft; an oil channel is arranged in the inner shaft; the surface of the inner shaft is provided with an oil port; and the internal shaft is communicated with the oil port. The internal shaft oil supply-type rotating shaft provided by the invention changes the hard connection mode between the ball and shaft body, uses the oil body for lubrication, reduces the friction between the parts and improved the service life.
Description
Technical field
The present invention relates to axle oil feeding type rotating shaft in one, relate to field of machine tool equipment.
Background technology
Lathe refers to manufacture the machine of machine, also known as machine-tool or toolroom machine, is called for short lathe traditionally.It is generally divided into Metal Cutting Machine Tool, forging machine tool and wood craft machines etc..In modern mechanical manufacturing, the method for processing equipment part is a lot: in addition to machining, also cast, forge, weld, punching press, extruding etc., in every case belong to the part that required precision is higher and surface roughness requirements is thinner, the most all finally need to process by the method for cutting on lathe.
In lathe, part is more, it is the basic kind of drive that axle moves, roller bearing bears bigger torsional forces and extrusion stress in the course of the work, fit clearance in use once occurs between axle and bearing, abrasion aggravation between axle journal and bearing inner race will be made, make equipment produce bigger vibration and noise, reduce the service behaviour of equipment.Due to the change of volume of material in work process, causing bearing easily to produce radial impact collision, can damage bearing time serious, roller bearing is scrapped, and causes malignant event.
Traditional method wants repair welding or brush plating or even replacing, but several method all exists certain drawback: the thermal stress that repair welding high temperature produces cannot be completely eliminated, and easily causes Material damage, causes parts bending or fracture occur；And Brush Plating is limited by coating layer thickness, easily peel off, and both the above method is all to use metallic prosthetic metal, it is impossible to change hard matching relationship, under each power comprehensive function, still can cause and again wear and tear；Scrap renewal and then need great amount of cost.
Summary of the invention
The present invention is directed to above-mentioned deficiency and provide axle oil feeding type rotating shaft in one.
The present invention adopts the following technical scheme that
Interior axle oil feeding type rotating shaft of the present invention, including outer shaft, interior axle, ball, described interior axle, and ball is set between outer shaft；Being provided with oil duct in described interior axle, the surface of interior axle is provided with hydraulic fluid port；Oil duct is connected with hydraulic fluid port.
Interior axle oil feeding type rotating shaft of the present invention, the described oil duct on interior axle is one or some.
Interior axle oil feeding type rotating shaft of the present invention, the width of described hydraulic fluid port is less than the diameter of ball.
Interior axle oil feeding type rotating shaft of the present invention, the cross section of described oil duct is trapezoidal.
Interior axle oil feeding type rotating shaft of the present invention, described ball contacts each other.
Interior axle oil feeding type rotating shaft of the present invention, described rotating shaft one end is provided with oil-in, is blocked by capping.
Beneficial effect
The interior axle oil feeding type rotating shaft that the present invention provides, changes the Hard link pattern between ball axis body, uses oil body to be lubricated, and the friction reduced between parts improves service life.
The interior axle oil feeding type rotating shaft that the present invention provides, can fill lubricating oil by oil transportation hole, carries out oil product and supplements.
The interior axle oil feeding type rotating shaft that the present invention provides, uses porous or single hole oil transportation, it is ensured that fill completion in whole rotating shaft, it is ensured that lubrication comprehensive.
The interior axle oil feeding type rotating shaft that the present invention provides, use disengaging type end face can countershaft in be carried out, improve further the service life of axle.

Detailed description of the invention
Purpose and technical scheme for making the embodiment of the present invention are clearer, below in conjunction with the accompanying drawing of the embodiment of the present invention, are clearly and completely described the technical scheme of the embodiment of the present invention.Obviously, described embodiment is a part of embodiment of the present invention rather than whole embodiments.Based on described embodiments of the invention, the every other embodiment that those of ordinary skill in the art are obtained on the premise of without creative work, broadly fall into the scope of protection of the invention:
As shown in the figure: interior axle oil feeding type rotating shaft, including outer shaft 1, interior axle 2, ball 3, described interior axle 2, and ball 3 is set between outer shaft 1；Being provided with oil duct 4 in described interior axle 2, the surface of interior axle 2 is provided with hydraulic fluid port 5；Oil duct 4 is connected with hydraulic fluid port 5.
Preferred version as interior axle oil feeding type rotating shaft of the present invention: the oil duct 4 on described interior axle 2 is one or some.
Preferred version as interior axle oil feeding type rotating shaft of the present invention: the width of described hydraulic fluid port 5 is less than the diameter of ball 3.
Preferred version as interior axle oil feeding type rotating shaft of the present invention: the cross section of described oil duct 4 is trapezoidal.
Preferred version as interior axle oil feeding type rotating shaft of the present invention: described ball 3 contacts each other.
Preferred version as interior axle oil feeding type rotating shaft of the present invention: described rotating shaft one end is provided with oil-in, is blocked by capping.
Those skilled in the art of the present technique are appreciated that unless otherwise defined, all terms used herein (including technical term and scientific terminology) have with the those of ordinary skill in art of the present invention be commonly understood by identical meaning.Should also be understood that those terms defined in such as general dictionary should be understood that have the meaning consistent with the meaning in the context of prior art, and unless defined as here, will not explain by idealization or the most formal implication.
The implication of heretofore described " connection " can be being directly connected between parts can also be by being indirectly connected with of other parts between parts.
The above; being only the present invention preferably detailed description of the invention, but protection scope of the present invention is not limited thereto, any those familiar with the art is in the technical scope that the invention discloses; the change that can readily occur in or replacement, all should contain within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with scope of the claims.
