Description
Technical field
The utility model is mainly concerned with the printing equipment field, refers in particular to a kind of printing machine wavers assembly.
Background technology
In printing machine, the transmission of wavers has dual mode, spur gear transmission and helical gear transmission.As shown in Figure 1, be the helical gear structure of a kind of employing.Transmission system is given wavers 9 transmission of power by helical gear 1, realizes the axial float of wavers 9 by play mechanism 5.Wherein, the outer shroud 301 of ball spline 3 is fixed on to be paid on the wallboard 2, and helical gear 1 links to each other with the interior ring 302 of ball spline 3.The right-hand member spindle nose of splined shaft 303 links to each other with the left end of the worm shaft 501 of play mechanism 5 by first shaft coupling 4 in the ball spline 3, and the right-hand member of worm shaft 501 links to each other with wavers 9 left end spindle noses by second shaft coupling 6.Wavers 9 is supported by ball bearing guide bushing 7, and ball bearing guide bushing 7 is contained on the wallboard 8, and power need be connected through first shaft coupling 4 and second shaft coupling 6 twice to wavers 9 through play mechanism 5 from helical gear 1.In this structure, because twice above-mentioned connection, cause from helical gear 1 to wavers 9 axiality to be difficult to guarantee, and the requirement on machining accuracy in the hole of pair wallboard 2 upper support ball splines 3 and wallboard 8 upper support ball bearing guide bushings 7 is very high, be difficult to guarantee, cause wavers 9 in the process of rotation and play, the entire mechanism imbalance influences printing quality.In addition, in actual use, also very difficult to lubricating of ball bearing guide bushing 7.
The utility model content
The technical problems to be solved in the utility model just is: at the technical problem that prior art exists, the utility model provides a kind of simple and compact for structure, with low cost, easy to assembly, printing machine wavers assembly that can guarantee wavers job stability and reliability.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of printing machine wavers assembly, comprise helical gear, wavers, play mechanism and ball spline, described helical gear is connected on the interior ring of ball of ball spline, it is characterized in that: the outer shroud of described ball spline is fixed on the bearing, described wavers is installed in the bearing by bearing, an end of splined shaft is connected in play mechanism in the described ball spline, and the other end of described splined shaft is inserted in the locating hole of offering on the wavers.
As further improvement of the utility model:
All be arranged with ringfeder on the link of the link of described splined shaft and play mechanism and splined shaft and wavers.
The outside of described wavers is arranged with axle sleeve, and described axle sleeve and bearing all are fixed on the wallboard of printing machine.
Offer the fuel feed hole that is used for to bearing lubrication on described bearing and the axle sleeve.
Compared with prior art, advantage of the present utility model is: of the present utility model simple and compact for structure, easy for installation, not only created condition for the appearance design of printing unit, and make that also wavers rotation and play are more steady; The utility model is lubricated convenient, under good lubrication, each support member also can reach best duty, finally guarantee for whole printing unit printing quality improves.
