Technical field
This utility model relates to mechanical transmission mechanism field, is specially the double sphere sliding rotating apparatus of a kind of screw rod transmission.
Background technology
In screw rod transmission, a kind of screw is had to maintain static the motion mode that screw mandrel rotates and does straight line.In the transmission of this kind of mode, screw mandrel head often does the linear motion advancing, retreating with operating mechanism, and screw mandrel head and screw mandrel body are fixed together, and screw mandrel head also rotates, moves along a straight line.The linear motion advancing, retreating only is done, so must there be a kind of rotary apparatus between screw mandrel head and operating mechanism because of operating mechanism.In general Machine Design, machine-building often with rolling bearing or spherical bearing as rotary apparatus.
In above-mentioned transmission (lead screw transmission that forward-reverse moves along a straight line is done by operating mechanism), two rolling bearings or a rolling bearing is often used to add the mode of a spherical bearing as rotary apparatus, but the rolling bearing fault in this kind of device is higher, on Long travel, heave-load device, fault rate is higher especially.Main cause is that rolling bearing is acted on by complex load, causes discontinuity to produce damage, and the fault rate of spherical bearing is much lower.
Utility model content
The purpose of this utility model is to provide a kind of novel screw rod transmission double sphere sliding rotating apparatus, reduces the fault of drive mechanism.
nullThe technical scheme realizing above-mentioned purpose is: the double sphere sliding rotating apparatus of a kind of screw rod transmission，It is characterized in that: include screw mandrel and the screw being connected on screw mandrel，One end of described screw mandrel is for connecting the drive mechanism driving screw mandrel to rotate，The other end of described screw mandrel connects slip rotating mechanism，Slip rotating mechanism includes the axle sleeve of one end open，The opening of described axle sleeve connects gland，The inner chamber of axle sleeve is provided with two and is connected to axle sleeve、Concave surface pad on gland，Two concave surface pads are oppositely arranged，And the most concave sphere in relative side，Double ball ring it is provided with between said two concave surface pad，The both sides end face of described pair of ball ring is respectively outer convex spherical，The outer convex spherical corresponding matching respectively of double ball ring both sides is arranged in the concave ball surfaces of respective side concave surface pad，One end of described screw mandrel sequentially passes through gland、It is connected with double ball rings after the concave surface pad being connected on gland.
As further improvement of the utility model, between described axle sleeve and gland, between axle sleeve and the concave surface pad being connected on axle sleeve, between gland and the concave surface pad being connected on gland, all removably connect between screw mandrel and double ball ring.
As further improvement of the utility model, described drive mechanism includes interconnective motor and decelerator.
As further improvement of the utility model, it is connected by spline between the outfan of described decelerator and screw mandrel.
The beneficial effects of the utility model are: sphere is adapted to the load of all directions, and has certralizing ability.In scheme, two spheres of double ball rings contact with both sides concave surface pad respectively when operating mechanism advances or retreats, and effectively adapt to the effect of complex load, the problem replacing damaging because rolling bearing is not suitable with complex load.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of slip rotating mechanism.
Detailed description of the invention
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, so that those skilled in the art can be better understood from this utility model and can be practiced, but illustrated embodiment is not as to restriction of the present utility model.
The double spherical rotary device of a kind of screw rod transmission described in the present embodiment, sees accompanying drawing 1, Fig. 2: it includes motor 1, decelerator 2, splined shaft 3, screw mandrel 4, screw 5, gland 6, axle sleeve 7, front concave surface pad 8, operating mechanism 9, double ball ring 10, back concave surface pad 11.
nullWherein screw 5 is connected on screw mandrel 4，One end of screw mandrel 4 is for connecting the drive mechanism driving screw mandrel to rotate，Drive mechanism includes interconnective motor 1 and decelerator 2，The other end of screw mandrel 4 connects slip rotating mechanism 12，Slip rotating mechanism 12 includes for connecting operating mechanism 9 and axle sleeve 7 that one end is opening，The opening of axle sleeve 7 connects gland 6，Connect on axle sleeve 7 and have back concave surface pad 11，Front concave surface pad 8 it is connected on gland 6，Front concave surface pad 8 and back concave surface pad 11 are oppositely arranged，And the most concave sphere in relative side，Double ball ring 10 it is provided with between front concave surface pad 8 and back concave surface pad 11，The both sides end face of double ball rings 10 is respectively outer convex spherical，The outer convex spherical corresponding matching respectively of double ball ring 10 both sides is arranged in the front concave surface pad 8 of correspondence and the concave ball surfaces of back concave surface pad 11，One end of screw mandrel 4 sequentially passes through gland 6、It is connected with double ball rings 10 after front concave surface pad 8.
One end that the outfan of decelerator 2 and screw mandrel 4 are connected with decelerator 2 is provided with hub splines, and splined shaft 3 one end is built in the spline housing of decelerator 2, and fixing with decelerator 2 is connected.The other end is built in the spline housing of screw mandrel 4, and screw mandrel can slide on splined shaft, and this scheme requires that screw mandrel 4 is relatively large in diameter, and screw mandrel 4 center is emptied, it is simple to the stretching motion of spline；Optionally, it is also possible to be connected fixing with screw mandrel 4 for splined shaft 3 or both are integrally formed.
Optical axis shape is made in one end that screw mandrel 4 is connected with slip rotating mechanism 12, and diameter is more smaller than screw mandrel path；Can be removably connected by multiple first screws between double ball rings 10 and the head circular shaft of screw mandrel 4.So it is easy to maintenance and assembling.
