Description
Technical field
The present invention relates to a kind of frock on the automatic coil winding machine, the jack shaft of using more specifically to a kind of winding machine.
Background technique
Jack shaft is as directly accepting power on motor or the motor and sending power to device that power is exported main shaft; Be widely used on machining center and other lathes or the mechanized equipment; It is decision drivign belt working life; Decompose belt load, eliminate belt and beat the realization main shaft by setting the key components that rotating speed accurately rotates.Yet general jack shaft is because the narrow limitation of material and structure is difficult to solve the Concentricity tolerance problem that produces because of high speed rotating.The present invention is exactly the solution that proposes to the Concentricity tolerance problem, and this invention is applied on the winding machine, can satisfy the requirement of high speed rotating and the accurate transmission of rotating speed.
Summary of the invention
The objective of the invention is to overcome the deficiency of existing technology, the jack shaft that provides a kind of winding machine to use, this jack shaft Concentricity tolerance when high speed rotating is less.
The scheme that the present invention solve the technical problem is: the jack shaft that a kind of winding machine is used; Comprise a core; The axle core comprises input end and output terminal; Said axle core passes Mandrel seat, is disposed with first end cap, clutch shaft bearing, axle core spacer, second bearing, second end cap, locking nut from input end to output terminal on the axle core; Locking nut is made up of nut portions and annulus portion, and the inner ring that second end cap and second bearing pass in annulus portion offsets; The inwall of Mandrel seat is provided with the protruding and circle groove of a circle, and rubber ring is arranged in the groove, and the outer ring of clutch shaft bearing is stuck between protruding and first end cap, and the outer surface and the rubber ring of second bearing offset; Be with spring and bearing washer on the axle core spacer, length of spring compressed is between bearing washer and convexity, and the outer ring of the bearing washer and second bearing offsets.
Locking nut is made up of nut portions and annulus portion; Locking nut and axle core screw-thread fit area have been increased; And the annulus portion of locking nut passes second end cap and directly offsets with the inner ring of second bearing; Not only be difficult for becoming flexible between locking nut and the axle core, the relation of closely cooperating of the locking nut and second bearing is also survivable.
Generally speaking, because second bearing is positioned at the output terminal of a core, the concussion at the second bearing place and jumping phenomena are obvious than the clutch shaft bearing place.The inwall of Mandrel seat is provided with a circle groove, and rubber ring is arranged in the groove, and this scheme can be alleviated second bearing beating on above-below direction, can also reduce the outer wall of second bearing and collision and the friction between the Mandrel seat inwall.Second bearing in the horizontal direction because the existence of spring, spring can absorb the vibrations in the horizontal direction of second bearing.The setting of rubber ring and spring makes second bearing stably move in the precalculated position.
It is protruding that the inwall of Mandrel seat is provided with a circle, and clutch shaft bearing is limited between protruding and first end cap, guarantees the fixing of clutch shaft bearing position.Simultaneously, protruding avoid when high speed operation for spring provides the support point of a power, the outer ring of the clutch shaft bearing and second bearing all has spring to come tensioning and the unstability brought.
In addition, all vitals of the present invention all are sleeved on the core, make the parts of whole jack shaft be securely fixed in the neutral position of a core through locking nut and spring, and structural reduction is mutually nested, installs compact.
The synergy of above characteristic can reduce this jack shaft Concentricity tolerance when high speed rotating to greatest extent.
As further technological scheme, the protuberance that a circle and the outer ring of clutch shaft bearing offset is set on said first end cap, it is circular that protuberance is, and the wall thickness of the wall thickness of protuberance and clutch shaft bearing outer ring is corresponding.
This programme is said corresponding, is meant that the wall thickness of protuberance is a bit larger tham or is slightly smaller than the wall thickness of clutch shaft bearing outer ring.Protuberance be provided with the heat radiation that is beneficial to clutch shaft bearing, prevent that simultaneously first end cap from contacting with the inner ring of clutch shaft bearing.
As further technological scheme again, said convexity is provided with chamfering in the contacting point with the outer ring of clutch shaft bearing, and said bearing washer is provided with chamfering in the contacting point with the outer ring of second bearing.
The setting of chamfering can be avoided the contacting of inner ring of protruding and clutch shaft bearing, and the contacting of the inner ring of bearing washer and second bearing, and prevents to influence jack shaft and rotates.
As technological scheme further; Said axle core has boss; The inner ring of clutch shaft bearing is fixed between boss and the axle core spacer, and boss is corresponding with the thickness of clutch shaft bearing inner ring with the thickness of clutch shaft bearing contacting point, and the wall thickness of a core spacer is corresponding with the thickness of clutch shaft bearing inner ring.
This programme is said corresponding, is meant that boss is a bit larger tham or is slightly smaller than the wall thickness of clutch shaft bearing inner ring at the thickness with the clutch shaft bearing contacting point, and the wall thickness of axle core spacer is a bit larger tham or is slightly smaller than the wall thickness of clutch shaft bearing inner ring.Between clutch shaft bearing and the axle core is interference fit, and boss and axle core spacer play the effect of auxiliary fixing clutch shaft bearing, to the qualification of thickness, help reducing the influence to the bearing ball part, help heat radiation.
In sum, the present invention has compact structure, reliable advantage, can reduce the Concentricity tolerance of jack shaft under the high-speed rotation state, and better heat stability.
