Description
Technical field:
The present invention relates to rubber processing machinery apparatus field, particularly relate to the screw drive of a kind of single screw rod Rubber Extruder
Set.
Background technology:
The screw rod operation characteristics of macintoss screw rod Rubber Extruder (including hot feeding and cold feeding) is the slow-speed of revolution, permanent torsion
Square.Generally with gear reduction box, motor is reduced to low speed and is improved driving torque at a high speed, to meet screw rod operating needs.Screw rod
Driving is certain by screw rod tail and gear reduction box hollow output shaft (main purpose of hollow axle is for cooling screw)
The connection of form realizes.
Single screw rod Rubber Extruder in early days, screw rod tail axle journal generally with (one or two is separated by 180 °) flat key or
Rectangular spline matches with reduction box hollow output shaft hole connection, does not design drive sleeve.So it is designed with its inherent shortcoming: feed
The driving gear of material roller gear pair generally uses and designs all-in-one-piece gear shaft form with screw rod tail, when extruding feeding, and tooth
The engagement of wheel set can make screw rod produce extra side force, add feeding zone impact (feeding roller to and wedge shape lead to
Road), screw rod will be caused to produce big flexural deformation, cause screw rod to engage bad with machine barrel scraping and feeding roller gear pair.
In order to overcome the defect of above-mentioned Earlier designs, some employings are by the driving gear Flat dey joint of feeding roller gear pair
Stretch out prolongation (may be considered the concept embryo of drive sleeve) in reduction box hollow output shaft, and screw rod tail axle journal is used
Flat key matches with hollow output shaft hole.The major defect of this design is when feeding overload causes the key damage of driving gear
Time, whole reduction box hollow output shaft can be made to scrap.
But, in most of the cases, the design of employing is feeding roller drive sleeve.In this type of design, drive sleeve
Rear end end face flat key or pin be connected with the front end surface of reduction box hollow output shaft, and with screw, drive sleeve is fixed on
On reduction box hollow output shaft end face, the front portion of drive sleeve is designed to the external tooth being meshed with the driven gear of feeding roller gear pair
Wheel, screw rod tail axle journal through feeding roller drive sleeve endoporus and is matched with reduction box hollow output shaft hole by involute spline
Close.This design defect includes: (1) feeding roller drive sleeve to be regulated and reduction box hollow output shaft, screw rod and feeding roller during assembling
The axiality of drive sleeve, centering regulation complexity；(2) reduction box hollow output shaft is designed with interior involute spline, processing difficulties；⑶
Screw rod tail is because of elongated through feeding roller drive sleeve, and cost is high.
Summary of the invention:
The present invention is in order to overcome the defect of existing feeding roller drive sleeve, it is provided that a kind of alignment is good, centering is easy to adjust,
Handling ease, advantageously reduce single screw rod screw rod for rubber extruder drive sleeve of extruder cost.
A kind of single screw rod screw rod for rubber extruder drive sleeve of the present invention, the interior involute spline at drive sleeve rear portion with
The outer involute spline of reduction box hollow output shaft matches, the interior involute spline in the middle part of drive sleeve and screw rod tail axle journal
Outer involute spline matches, and outer involute gear and feeding roller gear that drive sleeve is anterior constitute feeding roller gear pair.Described
Drive sleeve, it is possible to realize to screw rod and feeding roller integral drive.
Compared with prior art, the present invention has the beneficial effects that:
The most all interior involute splines design in drive sleeve, and reduction gearbox output shaft is only designed with outer involute spline, hold
Easily ensured the coaxial accuracy of part by machining, during assembling, only need to regulate the same of drive sleeve and reduction box hollow output shaft
Axle degree, centering easy to adjust and handling drive sleeve and screw rod easy.
2. drive sleeve couples with the involute spline of reduction gearbox output shaft, makes torque-transfer capability increase.
3. it is easily worked the outer involute spline of reduction gearbox output shaft, and screw rod tail length shortens, be also beneficial to reduce
Extruder cost.
Accompanying drawing illustrates:
The structure that Fig. 1 is the present invention and assembling schematic diagram
Wherein 1 is screw rod, and 2 is feeding pedestal, and 3 is reduction gearbox output shaft, and 4 is drive sleeve, and 5 is the gear on feeding roller, 6
For feeding roller.
Detailed description of the invention:
Below against accompanying drawing and the present invention is described further in conjunction with specific embodiments.
As it is shown in figure 1, a kind of single screw rod screw rod for rubber extruder drive sleeve, concrete structure is: screw rod 1 is arranged on feeding seat
In body 2, the interior involute spline at drive sleeve 4 rear portion matches with the outer involute spline of reduction gearbox output shaft 3, in drive sleeve 4
The interior involute spline in portion matches with the outer involute spline of screw rod 1 afterbody axle journal, the outer involute gear of drive sleeve 4 front portion
Feeding roller gear pair is constituted with the gear 5 of feeding roller 6.
The principle of the present invention is:
Moment of torsion and rotating speed are passed to drive sleeve 4 by involute spline by reduction gearbox output shaft 3, and drive sleeve 4 is again by gradually
Burst at the seams the cooperation of spline and gear, respectively moment of torsion and rotating speed are passed to screw rod 1 and feeding roller 6.
The concrete application approach of the present invention is a lot, and the above is only the preferred embodiment of the present invention, it is noted that for
For those skilled in the art, under the premise without departing from the principles of the invention, it is also possible to make some improvement, this
A little improvement also should be regarded as protection scope of the present invention.
