Abstract
The invention relates to the technical field of screws, in particular to a novel ball screw which is installed on various kinds of industrial equipment and precise instruments. The novel ball screw comprises a screw body and screw nuts, wherein the screw body is sleeved with the screw nuts. The screw nuts include the first screw nut and the second screw nut. A spacer is arranged between the first screw nut and the second screw nut. A flange is integrally formed on the first screw nut. A plurality of balls are arranged on the inner wall of the first screw nut and the inner wall of the second screw nut. Elbow pipe inverters are arranged on the screw nuts. Pressing plates are installed on the screw nuts. Sealing rings are arranged in the portions, making contact with the screw body, of the two ends of each screw nut. An oil delivery pipeline coaxial with the screw body is formed on the first screw nut. The novel ball screw is reasonable in design; the lubricating performance of the ball screw is improved, noise can be lowered when the balls rotate at a high speed, the abrasion resistance of the ball screw is improved, and the service life of the ball screw is prolonged; the novel ball screw has the advantage of being dustproof.
Description
Technical field
The present invention relates to leading screw technical field, especially a kind of new pattern rolling ball leading screw being installed on various industry equipment and precision type instrument.
Background technique
Ball screw is that rotation motion is converted into straight line motion, or is the desirable product of rotation motion by transform linear motion, is widely used in various industry equipment and precision type instrument.But traditional ball screw complex structure, install and keep in repair loaded down with trivial details, precision and stationary performance are all not high, and wear-resisting property is poor, greasy property is also bad, need often maintenance or change, after service time is long, the wearing and tearing of screw mandrel are very large, and can generate heat, the working life of screw mandrel can shorten, and reduces manufacturing efficiency, improves cost of production.Therefore, a kind of new technological scheme is needed to solve the problem.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, provides a kind of structure simple, the new pattern rolling ball leading screw of long service life.
The technical solution adopted for the present invention to solve the technical problems is: a kind of new pattern rolling ball leading screw, comprise leading screw and be set in the screw outside leading screw, screw comprises the first screw and the second screw, pad is provided with between first screw and the second screw, one-body molded on first screw have flange, described first screw and the second screw inwall are provided with multiple ball around leading screw screw winding, and screw is provided with the bend pipe reverser making ball form circulation loop, and screw is provided with the pressing plate of fixed bending tube reverser; The position that contacts with leading screw, described screw two ends is provided with seal ring, described first screw offers with leading screw homoaxial pipeline road.
Further, the first described screw, pad are fixedly connected with by locking plate with the second screw, and it is comparatively convenient to mount and dismount.
Further, described bend pipe reverser is resin reverser, can reduce noise when ball high speed rotating.
Further, described leading screw is high manganese leading screw, and wear-resisting property is good.
Further, described flange offers mounting hole.
The invention has the beneficial effects as follows: the present invention is reasonable in design, be provided with the greasy property that pipeline road can improve ball screw, adopt resin reverser, noise can be reduced when ball high speed rotating, leading screw is high manganese leading screw, improves the wear-resisting property of ball screw, increases the service life, the position that contacts with leading screw, screw two ends is provided with seal ring, has dust-proof advantage.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
1. first screws, 2. the second screw, 3. flange, 4. leading screw, 5. pad, 6. pressing plate, 7. seal ring, 8. locking plate, 9. ball, 10. bend pipe reverser in figure, 11. pipeline roads, 12. mounting holes.
Embodiment
The present invention is further illustrated with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
A kind of new pattern rolling ball leading screw as shown in Figure 1, the screw comprising leading screw 4 and be set in outside leading screw 4, screw comprises the first screw 1 and the second screw 2, pad 5 is provided with between first screw 1 and the second screw 2, one-body molded on first screw 1 have flange 3, first screw 1 and the second screw 2 inwall are provided with multiple ball 9 around leading screw 4 screw winding, and screw is provided with the bend pipe reverser 10 making ball 9 form circulation loop, and screw is provided with the pressing plate 6 of fixed bending tube reverser 10; The position that contacts with leading screw 4, screw two ends is provided with seal ring 7, the first screw 1 offers the homoaxial pipeline road 11 with leading screw 4.
First screw 1, pad 5 are fixedly connected with by locking plate 8 with the second screw 2; Bend pipe reverser 10 is resin reverser; Leading screw 4 is high manganese leading screw; Flange 3 offers mounting hole 12.
Leading screw 4 starts to rotate under motor drives, and ball 9 forms circulation loop bend pipe reverser 10 in, thus the first screw 1 of being fixedly connected with of drive and the second screw 2 slide on leading screw 4.Pipeline road 11 injects lubricant oil, improves the greasy property of ball screw; The position that contacts with leading screw 4 at screw two ends is provided with seal ring 7, can be dust-proof.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
