Abstract
The utility model discloses a kind of trapezoidal screw nut, including flange, nut body, the gap that disappears nut, anti-backlash and screw；Flange one end attaching nut's body, and set through hole in flange and nut body, through hole runs through flange and nut body, the nut body includes first step and second step, spring eye is set on the outside of the second step, the gap that disappears nut sets spring eye close to second step side, and nut body is connected with the gap nut that disappears by the dowel hole of second step, and the anti-backlash, which inserts in, to be disappeared in gap nut and nut body and fixed by the screw in gap nut that disappears.The trapezoidal screw of the utility model is had the following advantages with nut：The gap that disappears type can play the role of eliminating thread pitch, ensure the stability of nut, strengthen practicality with disappear gap nut and 3 anti-backlash.
Description
Technical field
A kind of nut is the utility model is related to, more precisely, being a kind of trapezoidal screw nut.
Background technology
Traditional trapezoidal screw nut includes flange and nut body, and flange connects integral with nut, and centre is
The through hole of trapezoidal screw, as shown in Figure 1, but leading screw usually can cause nut body all in rotary state, long-time service
There is gap and causes to loosen in inside, and is often difficult to discover, and replaces inconvenience.
Utility model content
The utility model is mainly the technical problem solved present in the prior art, so as to provide a kind of trapezoidal screw spiral shell
Mother, solves the problems, such as that connection easily loosens, ensures the stability of apparatus.
The above-mentioned technical problem of the utility model is mainly what is be addressed by following technical proposals：A kind of trapezoidal screw
With nut, including flange, nut body, the gap that disappears nut, anti-backlash and screw；Flange one end attaching nut's sheet
Body, and through hole is set in flange and nut body, through hole run through flange and nut body, the nut body include first step and
Second step, sets spring eye on the outside of the second step, and the gap that disappears nut sets spring eye close to second step side, nut body and
The gap that disappears nut is connected by the dowel hole of second step, and the anti-backlash, which inserts in, to be disappeared in gap nut and nut body and pass through
Screw in the gap that disappears nut is fixed.
The circumference of flange direction is evenly distributed with four circular holes, for being connected with adjacent parts.
The first step diameter of the nut body is more than second step diameter.
The spring eye and dowel hole are three and interval is uniformly distributed.
The screw is two, is juxtaposed on the outside of the anti-backlash to disappear in gap nut.
The nut body, flange and the gap nut that disappears are that one-ton brass makes, wear-resisting and be suitable for high-speed motion occasion.
The trapezoidal screw of the utility model is had the following advantages with nut：The gap that disappears type is with disappear gap nut and 3 gap bullets that disappear
Spring, can play the role of eliminating thread pitch, ensure the stability of nut, strengthen practicality.
Brief description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment

Embodiment
The preferred embodiment of the utility model is described in detail in 1-4 below in conjunction with the accompanying drawings, so that the utility model
Advantages and features can be easier to be readily appreciated by one skilled in the art, so as to be made to the scope of protection of the utility model apparent
Clearly define.
As shown in Figure 2, Figure 3, Figure 4, a kind of trapezoidal screw nut, including flange (1), nut body (2), the gap that disappears nut
(3), anti-backlash (4) and screw (5)；Flange (1) one end attaching nut's body (2), and flange (1) and nut sheet
Through hole is set in body (2), through hole runs through flange and nut body, and the nut body (2) includes first step and second step, institute
State and spring eye (6) is set on the outside of second step, the gap that disappears nut (3) sets spring eye (6), nut body (2) close to second step side
Gap nut (3) is connected by the dowel hole (7) of second step with disappearing, and the anti-backlash (4) inserts in disappear gap nut (3) and spiral shell
It is in maternal body (2) and fixed by the screw (5) in gap nut (3) that disappears.
Flange (1) circumferencial direction is evenly distributed with four circular holes, for being connected with adjacent parts.
The first step diameter of the nut body (2) is more than second step diameter.
The spring eye (6) and dowel hole (7) are three and interval is uniformly distributed.
The screw (5) is two, is juxtaposed on the outside of the anti-backlash (4) to disappear in gap nut (3).
The nut body (2), flange (1) and the gap nut (3) that disappears be one-ton brass make, it is wear-resisting and suitable at a high speed transport
Dynamic occasion.
The trapezoidal screw of the utility model is had the following advantages with nut：The gap that disappears type is with disappear gap nut (3) and 3 gaps that disappear
Spring (4), can play the role of eliminating thread pitch, ensure the stability of nut, strengthen practicality.
Not limited to this, any change or replacement expected without creative work, should all cover in the utility model
Protection domain within.Therefore, the scope of protection of the utility model should be determined by the scope of protection defined in the claims.
