Description
Technical Field
The utility model relates to a ball spare part technical field specifically is a dust ring for screw nut.
Background
The ball screw is the most commonly used transmission element on tool machinery and precision machinery, and has the main function of converting rotary motion into linear motion or converting torque into axial repeated acting force, and has the characteristics of high precision, reversibility and high efficiency. Ball is in the assembly use, and its screw nut both ends need imbed the dustproof effect of circling and preventing dust and elasticity pretension, and current dust ring is O shape circle, simple structure, and this structure dust ring appears becoming flexible, the problem of skidding easily after the assembly, for this reason, the utility model provides a dust ring is with good above-mentioned drawback of solution for screw nut.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a dust ring for screw nut to solve the problem that proposes among the above-mentioned background art.
The above utility model discloses an above-mentioned utility model purpose can realize through following technical scheme: the utility model provides a dust ring for screw nut, includes the dust ring body, one side of dust ring body, be located interior edge department an organic whole and mould plastics and be the connecting portion of annular structure, an organic whole is connected with the tooth that is annular distribution between the outer wall of connecting portion and the lateral wall of dust ring body.
The utility model discloses further set up to: the outer diameter of the dustproof ring body is smaller than the inner diameter of an annular groove of the lead screw nut, wherein the annular groove is used for pre-installing the dustproof ring, and the outer diameter of the tooth is larger than the inner diameter of the annular groove of the lead screw nut, wherein the annular groove is used for pre-installing the dustproof ring.
The utility model discloses further set up to: the dustproof ring is a tetrafluoroethylene dustproof ring; the outer diameter of the tooth is larger than the inner diameter of an annular groove of a lead screw nut for pre-installing a dust ring by 1-3 mm.
Compared with the prior art, the utility model provides a dust ring for screw nut possesses following beneficial effect: the utility model discloses add tooth on the basis of current dust ring, on carrying out the dirt-proof basis of screw nut assembly dust ring, can increase the friction between dust ring and the screw nut, prevent that the dust ring is not hard up and slide, improved dirt-proof stability.
Drawings
FIG. 1 is a schematic structural view of the present invention;
in the figure: 1. a dust ring body; 2. a connecting portion; 3. and (4) teeth.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example (b): referring to fig. 1, the present invention provides a technical solution: a dustproof ring for a lead screw nut is integrally formed by injection molding of tetrafluoroethylene. The dust ring comprises a dust ring body 1, the outer diameter of the dust ring body 1 is smaller than the inner diameter of an annular groove of a lead screw nut for preassembling the dust ring, one side of the dust ring body 1 is positioned at an inner edge, a connecting part 2 which is of an annular structure is integrally molded, teeth 3 which are annularly distributed are integrally connected between the outer wall of the connecting part 2 and the side wall of the dust ring body 1, the teeth 3 surround and form a gear-shaped structure, and the outer diameter of the teeth 3 is larger than the inner diameter of the annular groove of the lead screw nut for preassembling the dust ring by 2 mm.
The utility model discloses when assembling the use, one side that is located tooth 3 with dust ring body 1 is aimed at lead screw nut and is used for the ring channel of pre-installation dust ring and carry out the pressfitting fixed can, because of tooth 3's external diameter slightly is greater than the internal diameter of ring channel, tooth 3 is fixed with the lateral wall of ring channel tightly pressfitting, on dust ring body 1 plays the basis of dustproof effect, can increase the friction between dust ring and the lead screw nut, prevent that dust ring is not hard up and slide, improved dirt-proof stability.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
