Description
Technical field
The utility model 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 accurate key components of rotating of rotating speed.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 Rotation Speed.The utility model is exactly the solution that proposes for the Concentricity tolerance problem, and this model utility is applied on the winding machine, can satisfy the requirement of High Rotation Speed and the accurate transmission of rotating speed.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, and the jack shaft that provides a kind of winding machine to use, this jack shaft Concentricity tolerance when High Rotation Speed is less.
The scheme that the utility model solve the technical problem is: the jack shaft that a kind of winding machine is used, comprise the axle core, the axle core comprises input end and output terminal, described axle core passes Mandrel seat, is disposed with the first end cap, clutch shaft bearing, axle core spacer, the second bearing, the second end cap, locking nut on the axle core from input end to output terminal; Locking nut is comprised of nut portions and annulus section, and the inner ring that the second end cap and the second bearing pass in annulus section offsets; The inwall of Mandrel seat arranges a circle projection and a circle groove, and rubber ring is arranged in the groove, and the outer ring of clutch shaft bearing is stuck between projection and the first end cap, and outer surface and the rubber ring of the second bearing offset; Cover has spring and bearing washer on the axle core spacer, and spring-compressed is between bearing washer and projection, and the outer ring of bearing washer and the second bearing offsets.
Locking nut is comprised of nut portions and annulus section, locking nut and axle core screw-thread fit area have been increased, and the second end cap passes directly in the annulus section of locking nut and the inner ring of the second bearing offsets, not only be difficult between locking nut and the axle core becoming flexible, the relation of closely cooperating of locking nut and the second bearing is also survivable.
In general, because the second bearing is positioned at the output terminal of axle core, the concussion at the second bearing place and jumping phenomena are obvious than the clutch shaft bearing place.The inwall of Mandrel seat arranges a circle groove, and rubber ring is arranged in the groove, and this scheme can be alleviated the second bearing beating on above-below direction, can also reduce the outer wall of the second bearing and collision and the friction between the Mandrel seat inwall.The second bearing in the horizontal direction because the existence of spring, spring can absorb the vibrations in the horizontal direction of the second bearing.The setting of rubber ring and spring makes the second bearing stably move in the precalculated position.
The inwall of Mandrel seat arranges a circle projection, and clutch shaft bearing is limited between projection and the first end cap, guarantees the fixing of clutch shaft bearing position.Simultaneously, projection provides the support point of a power for spring, avoids when high speed operation, and the outer ring of clutch shaft bearing and the second bearing all has spring to come tensioning and the unstability brought.
In addition, all vitals of the utility model all are sleeved on the axle core, make the parts of whole jack shaft be securely fixed in the neutral position of axle core by locking nut and spring, and structural reduction is mutually nested, installs compact.
The synergy of above feature can reduce this jack shaft Concentricity tolerance when High Rotation Speed to greatest extent.
As further technological scheme, described first end covers the protuberance that a circle and the outer ring of clutch shaft bearing offset is set, and 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, refers to 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 the first end cap from contacting with the inner ring of clutch shaft bearing.
As technological scheme further, described projection is provided with chamfering in the contacting point with the outer ring of clutch shaft bearing, and described bearing washer is provided with chamfering in the contacting point with the outer ring of the second bearing.
The setting of chamfering can be avoided contacting of projection and the inner ring of clutch shaft bearing, and the contacting of the inner ring of bearing washer and the second bearing, and prevents from affecting jack shaft and rotates.
As technological scheme further, described 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 the thickness of clutch shaft bearing contacting point and clutch shaft bearing inner ring, and the wall thickness of axle core spacer is corresponding with the thickness of clutch shaft bearing inner ring.
This programme is said corresponding, refers to 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.Be interference fit between clutch shaft bearing and the axle core, boss and axle core spacer play the auxiliary fixedly effect of clutch shaft bearing, to the restriction of thickness, are conducive to reduce the impact on the bearing ball part, are conducive to heat radiation.
In sum, the utlity model has compact structure, reliable advantage, can reduce the Concentricity tolerance of jack shaft under the high speed rotating state, and better heat stability.
