Abstract
One is used at the same line but the coupling that not necessarily coaxial a pair of axle links together.Comprise a pair ofly being connected sleeve and interconnective with it outer hull shape device on the axle by key, and between coupling and shell as a series of circular roller of connecting element.
Description
The invention provides a kind of correct coupling of arranging of a pair of of connecting head that is used for.The structure of above-mentioned coupling makes, even some off-centre of two connection, it still can be without any the work of fault ground.
In addition, coupling of the present invention only is made up of less elements.Compare it is easy to install and can reduce maintenance with conventional device.
The known coupling that many different types are arranged can be used to a pair of axle of correct some slight eccentricity of arranging of connecting head.
For example, known rubber pin coupler, form by a pair of flange plate that has sleeve in fact, sleeve is connected by key with the end of axle, the a series of staggered pin that has cantilever to install thereon, these pins are wrapped in the hollow rubber element, and with clutch disk on the corresponding hole of making be meshed.
, the coupling of this class, restricted to the eccentric degree of axle, because the wearing and tearing of pin rubber cover in one period, it is easy to damage.
Other coupling, as the Falk formula, it comprises a pair of flange plate that has sleeve, sleeve is connected with axle head by key, above-mentioned disk is equipped with a series of outstanding elements, be connected with another disk by flexible metal tape, between two parts of its permission composition coupling limited moving back and forth can take place.
This example also can only allow a spot of off-centre.Because its complex structure, cost is very high.
Also have known paul pawl coupling, wherein be fixed on two sleeves on the axle and be provided with tooth along circumference, this tooth is meshed with the internal tooth of outer hull shape device, and two sleeves are linked together.These teeth all have circular cross section, in order that allow axle that slight skew is arranged.But be no more than 2-3 ° at most.
, the coupling of this class is not immaculate yet, and reason has two, and the manufacturing that the first has the profile of tooth of circular cross section is quite expensive; It two is that frictional force in the attachment portion makes coupling self produce wearing and tearing and reduced working life.
In order to eliminate above-mentioned shortcoming, the invention provides a kind of coupling by a series of circular roller transmitting movements.
After this coupling was installed, can make two semiaxis offset each other approximately was the twice of known class like coupling, but did not have the latter to be easy to wear and tear and shortcoming that the manufacturing expense height is brought.
With reference to accompanying drawing, the present invention will be explained in detail by embodiment.
Fig. 1 is the partial sectional view of coupling of the present invention.
Fig. 2 is the view of the edge of the coupling direction vertical with Fig. 1 line of vision.
Coupling of the present invention is to make like this:
Be placed on the same straight line, but a pair of semiaxis 1 and 2 of coaxial line necessarily, link together by key or other known device, two sleeves 3, a circular baffle ring 5 is equipped with at 4 opposing side place, have a series of axial groove 6 on the sleeve, be equipped with on this groove and the as many circular roller 7 of groove quantity, it has been the element of transmitting movement effect.
Half housing interconnects by bolt 10 or other similar device, and a pair of skeleton shape seal washer 11 is contained between sleeve and the shell simultaneously, plays the effect of seal lubrication element.
Circular baffle ring 5 has circular cross-section, so that hub being mounted becomes with respect to shell deflection more or less.
Certainly, the quantity and the size of circular roller and bolt 10 depend on the moment of torsion that will transmit.
Owing to used circular roller,, between the contact surface of roller and corresponding seat, also can realize rolling motion even two semiaxis mutual alignments are eccentric.By comparison, in existing apparatus, adopted, be generally sliding contact surface-, and with regard to rubber column coupling and " Falk " coupling with regard to paul pawl coupling-because frictional force and distortion can produce heat, can consumed energy and make element heavy wear.
According to the feature that is described, coupling of the present invention is compared with existing scheme, has the relative offset except allowing two axles, and its job failure seldom has long Endurance life.
Claims (3)
1, one is used on the same line but the coupling that not necessarily coaxial a pair of axle links together, and it comprises and a pair ofly is connected sleeve and interconnective with it outer hull shape device on the axle by key.It is characterized in that: the connecting element between sleeve and shell is many circular rollers.
2, at the coupling of transmitting movement on the same line but between the not necessarily coaxial a pair of axle, it is characterized in that comprising: a pair of sleeve that is connected separately spool by key has a series of circumferential axial grooves on it.
A pair of half housing that is installed on the described sleeve and is mutually permanently connected has the corresponding groove in position of groove on a series of and the sleeve at the internal surface of shell.
A series of circular rollers that are inserted in the cavity of forming by above-mentioned a pair of groove.
According to the coupling of claim 2, it is characterized in that 3, sleeve ends is shaped on ring-type arc baffle ring, settle described roller in the groove on above-mentioned ring-type baffle ring.
