Together, screw rod head also makes rotating motion, moves along a straight line.The linear motion for advancing, retreating only is done because of operating mechanism, so
There must be a kind of rotating device between screw rod head and operating mechanism.Often with rolling in general Machine Design, machine-building
Dynamic bearing or spherical bearing are as rotating device.
In above-mentioned transmission (lead screw transmission that forward-reverse linear motion does in operating mechanism), two axis of rolling are often used
It holds or a rolling bearing adds the mode of a spherical bearing as rotating device, but the rolling bearing in this kind of device
Failure is higher, and especially failure rate is higher on long stroke, heave-load device.Main cause is work of the rolling bearing by complex load
With, lead to discontinuity and generates damage, and the failure rate of spherical bearing is much lower.
Summary of the invention
The purpose of the present invention is to provide a kind of double spherical surface sliding rotating apparatus of novel screw rod transmission, reduce transmission mechanism
Failure.
Realizing the technical solution of above-mentioned purpose is: a kind of double spherical surface sliding rotating apparatus of screw rod transmission, it is characterised in that: packet
The screw for including screw rod and being connected on screw rod, one end of the screw rod are used to connect the driving mechanism of driving screw rod rotation, institute
The other end for stating screw rod is connected with sliding rotating mechanism, and sliding rotating mechanism includes axle sleeve open at one end, and the axle sleeve is opened
Mouthful end connects gland, the inner cavity setting of axle sleeve there are two be connected to axle sleeve, the Concave pad on gland, two Concave pads are opposite
It is arranged, and the concave spherical surface in opposite side, double ball rings, double ball rings is provided between described two Concave pads
Both sides of the face be respectively outer convex spherical, the outer convex spherical of double ball ring two sides, which respectively corresponds, to be equipped in respective side Concave pad
Concave ball surfaces in, one end of the screw rod sequentially passes through gland, connect after the Concave pad that is connected on gland with double ball rings.
As a further improvement of the present invention, the Concave pad connected between the axle sleeve and gland, on axle sleeve and axle sleeve it
Between, be detachably connected between the Concave pad that is connected on gland and gland, between screw rod and double ball rings.
As a further improvement of the present invention, the driving mechanism includes motor and retarder interconnected.
As a further improvement of the present invention, it is connected between the output end and screw rod of the retarder by spline.
The beneficial effects of the present invention are: spherical surface is adapted to the load of all directions, and has certralizing ability.In scheme
Two spherical surfaces of double ball rings are contacted with two sides Concave pad respectively when operating mechanism advances or retreats, and effectively adapt to complexity
The effect of load, instead of because rolling bearing is not suitable with complex load damage the problem of.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the structural schematic diagram for sliding rotating mechanism.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples, so that those skilled in the art can be with
It better understands the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
A kind of double spherical rotary devices of screw rod transmission described in the present embodiment, referring to attached drawing 1, Fig. 2: it includes motor 1, subtracts
Fast device 2, splined shaft 3, screw rod 4, screw 5, gland 6, axle sleeve 7, preceding Concave pad 8, operating mechanism 9, double ball rings 10, back concave surface pad
11。
Wherein screw 5 is connected on screw rod 4, and one end of screw rod 4 is used to connect the driving mechanism of driving screw rod rotation, driving
Mechanism includes motor 1 and retarder 2 interconnected, and the other end of screw rod 4 is connected with sliding rotating mechanism 12, slides whirler
Structure 12 includes for connecting operating mechanism 9 and one end is the axle sleeve 7 of opening, and the open end of axle sleeve 7 connects gland 6, on axle sleeve 7
It is connected with back concave surface pad 11, Concave pad 8 before being connected separately on gland 6, preceding Concave pad 8 and back concave surface pad 11 are oppositely arranged, and
And the concave spherical surface in opposite side, double ball rings 10, double ball rings 10 are provided between preceding Concave pad 8 and back concave surface pad 11
Both sides of the face be respectively outer convex spherical, the outer convex spherical of double 10 two sides of ball ring, which respectively corresponds, to be equipped with corresponding preceding recessed
In the concave ball surfaces of face pad 8 and back concave surface pad 11, one end of screw rod 4 sequentially pass through after gland 6, preceding Concave pad 8 with double ball rings
