Description

High-bearing-capacity, high-speed, bidirectional, double-bolt extruder
The invention belongs to field of plastics processing, what it related to is a kind of twin-screw plastic extruder, particularly have to rotate in the same way at a high speed and have simultaneously the two-way twin-screw plastic extruder series of high speed similarities and differences verticity again, mixing, enhancing, the modification of plastics had both been can be used for, technologies such as painted granulation can be used for producing extruding of abnormity and composite plastic section bar and sheet material again.
The twin-screw plastic extruder nearly all is only to have single steering behaviour in the prior art, and as co-rotating twin screw extruder, it has the good advantage of melting effect, and its rotating speed of PCM series extruder of producing as Japanese pond shellfish company is 30~300r.p.m.Heterodromy double-screw extruder can adopt axially, Totally-enclosed-type screw thread radially, and as the TED series double screw extruder that Toshiba Corp produces, its rotating speed of plastics that is used for production heat endurance and mobile difference only is 12~36r.p.m.The engagement of the profile of tooth of output shaft can only obtain monolateral engagement in the transmission device of prior art, or in two output shafts, only obtain a rooted tooth axle and have bilateral engagement, as the EZ series co-rotating twin screw extruder transmission device of Germany special 2852445 and 3009398, there is the defect end of twin shaft axial thrust bearing capacity inequality in it owing to be subjected to spatial constraints.The life-span of its journal bearing and tooth is very short during the turn up 300r.p.m left and right sides of the double screw extruder of the monolateral engagement of output gear shaft in the prior art, but as a φ 60mm extruder stop production and can lose about 6000 yuan of RMB in 1 hour.
The objective of the invention is for provide high-speed bidirectional twin-screw plastic extruder transmission device that a kind of existing verticity in the same way has incorgruous verticity again it can adapt to the production of various plastics extruded products.And can solve tooth and too short addiction end of journal bearing life-span, and a kind of two-way double output shaft structure of bilateral engagement that has promptly is provided, such device is zero in the moment of flexure sum of perfect condition lower gear.Thereby eliminated the stress concentration phenomenon behind the tooth bending shaft, reached 2.0 o'clock this factor ofs stress concentration at coefficient of facewidth and reach more than 1.5, contained after the bilateral engagement factor so profile of tooth intensity of the present invention has improved more than 3 times.Owing to be that the support reaction of the rolling bearing 10,11 at bilateral engagement input and output gear axle two ends is zero and because the unsymmetrical load that actual mismachining tolerance is brought only is about 15%, so actual raising of journal bearing life-span of the present invention (100/15) 3.3Promptly 523 times.
Of the present invention being characterized as: driving a pair of output shaft drive is by input gear shaft 1, input gear shaft 2, sun gear 3, sun gear 4, ring gear 5, ring gear 6, output gear shaft 7, output gear shaft 8, sun gear axle 9,4 bearings 10 at input gear shaft 1,2 two ends, 4 bearings 11 at output gear shaft 7,8 two ends, 4 bearings 12 of sun gear 3,4,4 rolling bearings 13 of ring gear 5,6.And housing 14 is formed.Sun gear 3 is axially concentric with sun gear 4, and their rolling bearings 12 separately are bearing on its common sun gear axle 9, and the two ends of sun gear axle 9 are cemented on the housing.Sun gear 3,4 separately with ring gear 5,6 radial concentric, ring gear 5 also is bearing on 2 rolling bearings 13 separately with ring gear 6 is axially concentric, the outer ring of rolling bearing 13 is cemented on the housing, the tooth of input gear shaft 1 and the tooth of output gear shaft 7 are in the same plane, and the facewidth equates, their radially inner side is meshed with sun gear 3 respectively, the outside is meshed with ring gear 5 respectively, the tooth of input gear shaft 2 is in the same plane with the tooth of output gear shaft 8 and the facewidth equates, their radially inner side is meshed with sun gear 4 respectively, the outside is meshed with ring gear 6 respectively, two rolling bearings 10 and two rolling bearings 11 are in the same level of sun gear 3 and ring gear 5 left ends, and two rolling bearings 10 and two rolling bearings 11 are in the same level of sun gear 4 and ring gear 6 right-hand members in addition.The centre-to-centre spacing of two output gear shafts is taken from the radially Y-axis line that its center separately of screw rod centre-to-centre spacing in the double screw extruder seriation is symmetrical in sun gear.The center of two power shafts is symmetrical in radially Y-axis line and be positioned at two quadrants beyond two output gear shaft place quadrants of solar shaft.Input gear shaft 1,2 and output gear shaft 7,8 speed of walking around is identical, rotation in the same way between the input gear shaft 1,2, then rotation in the same way between the output gear shaft 7,8, then incorgruous rotation between the output gear shaft 7,8 of incorgruous rotation between the input gear shaft 1,2.Drive input gear shaft 1,2 and adopt common gear reduction and reversing arrangement.Need only change two screw rods (in the same way or incorgruous) during production.And operate the production that general normal reversing arrangement can be realized another kind of rotation mode.Need measuring of incorgruous rotation extruder is about homodromal 3 times in reality is produced, and can make the shaft rotating speed of incorgruous rotation extruder bring up to 400~500r.p.m by present general 36r.p.m owing to improved the bearing capacity of transmission series.Therefore not only enlarge the scope of application, improved output widely, and solved the main too short addiction end of component life in addition.
Its screw diameter of two-way twin-screw plastic extruder series of the present invention from φ 25mm to φ 600mm rotating speed by 30r.p.m to 500r.p.m.
