Abstract
The utility model discloses a kind of triroller gate movement main shaft, comprise helical thread portion, bearing A mounting portion, keyway A, little U-type groove, keyway B, the bearing B mounting portion of the shaft shoulder and afterbody, the utility model applies to the drive part of triroller gate, for bearing and rotating disk are played a supporting role.Top helical thread portion is used for mounting nuts to be played and index plate connection function, and the keyway A that triroller gate main shaft is arranged and keyway B is respectively used to install rotating disk and fixed tray; Little U-type groove is provided with at afterbody, and middle porose, facilitate clamping when triroller gate main shaft manufactures and processing like this.The utility model is reasonable in design, and structure is simple, and easy to process, cost is lower.
Description
Technical field
The utility model relates to the transmission device of gate inhibition, particularly a kind of triroller gate movement main shaft.
Background technique
Nowadays triroller gate receives tourist attraction, school, and the parents such as enterprise look at, and the quantity of demand also constantly increases; Certainly also just more and more harsher to the requirement of triroller gate each several part.Main shaft particularly in triroller gate movement drive part, to this main shaft no matter in intensity, rigidity or size have specific requirement.Spindle design reasonable, long service life, manufacturing price is cheap, easily installs; These are exactly a kind of trend of current axle class.
In order to better cater to and solve above-mentioned trend, the utility model provides a kind of triroller gate movement main shaft at this.
Model utility content
The purpose of this utility model is to provide a kind of design ingenious at this, and transmission is accurate, and reliability is high, and structure is simple, assembling and triroller gate movement main shaft easy to maintenance.
The utility model is achieved in that a kind of triroller gate movement main shaft of structure, and its top is provided with helical thread portion, and afterbody is provided with little U-type groove, is provided with bearing A mounting portion and keyway below helical thread portion; Side, bearing A mounting portion is the shaft shoulder, and shaft shoulder lower end is provided with keyway A, is bearing B mounting portion above the little U-type groove of afterbody.
The little U-type groove part of afterbody is provided with the hole of certain depth; Bearing A mounting portion is for installing bearing A, and keyway A for installing square key, and is used in combination with rotating disk keyway; Helical thread portion be used for mounting nuts and with the index plate of triroller gate with the use of, when the little U-type groove that main shaft tail is established and cone shape hole spindle processing, convenient clamping, is beneficial to the machine shaping of axle.
The utility model tool has the following advantages:
Advantage one: the utility model structure is simple, and load and unload very convenient, it is very convenient to safeguard; Physical life is also long.
Advantage three: the utility model easily manufactures, manufacture cost is also low; There is good economic performance, be suitable for large range promotion use.
