Abstract
A plastics extruder with dual screws and parallel axles features three-point engagement, 3 times higher strength than ordinary tooth form and zero-load radial bearing.
Description
Technical field: what the present invention relates to is the plastic processing machinery field, the moment distribution of particularly incorgruous rotation parallel axes twin-screw plastic extruder and transmission mechanism and journal bearing mechanism.
Background technology: in the prior art, the twin-screw plastic extruder is applied to the granulation, painted, mixing of plastics widely, in the batcher of plastic sheeting, plastic material, tubing production and plastic injection equipment.Because it has the intermeshing screw rod of a pair of thread, make plastic product obtain sufficient homogenize therein, these characteristics are that single screw rod can't be compared, and can't satisfy the needs that growing double screw extruder develops to high speed, big L/D ratio, high pulling torque direction but be defined the locus that makes between two screw rods just because of the center of two screw rods.
Summary of the invention: the moment distributor gear that is used for anisotropic parallel axle double screw extruder, it is characterized by: two are meshed with bigger carrier gear 3 and carrier gear 4 symmetrically by the be meshed side separately of the gear 1 of the opposite output gear shaft of direction of rotation and gear 2 of a pair of external tooth mutually, the meshing point of the meshing point of gear 1 and carrier gear 3 and gear 2 and gear 4 is that the common point of contact of reference circle on the tangent line of the reference circle points of tangency of gear 1 and gear 2 with carrier gear 3 and carrier gear 4 is cut to condition mutually, the opposite side of gear 1 and gear 2 is meshed with bigger carrier gear 5 and carrier gear 6 symmetrically separately, and the meshing point of the meshing point of gear 1 and carrier gear 5 and gear 2 and carrier gear 6 is that the common point of contact of reference circle on the other end tangent line of the reference circle points of tangency of gear 1 and gear 2 with carrier gear 5 and carrier gear 6 is cut to condition mutually.The number of teeth of gear 1,2 is identical, and the number of teeth of gear 3,4,5,6 is identical.
Inventive principle: six gear type counter rotation twin screw extruder transmission mechanism output gear shafts 1, the vector of 2 meshing point counter-force is to be clockwise or anticlockwise sealing triangular form, so bearing is carried in its bearing system zero, because gear 3,4 meshing point and gear and 5,6 meshing point is at gear 1, on the tangent line of 2 meshing points, so can obtain gear 1, meshing point between 2 is to gear 1 and carrier gear 3, meshing point between 5 is to 2 angle α of X-axis line and gear 2 and gear 4, between 6 to 2 angle α of X-axis line, with gear 3, link to gear 1 between 4 centers, 3 the line of centres is to 2 angle β of X-axis line, gear 2,4 lines of centres to 2 angle β of X-axis line be supplementary angles, be alpha+beta=180 °, and at gear 1,2 meshing point Y-axis line both sides and gears 1,2 meshing point X-axis line both sides all have symmetry, so interference can not occur between the meshing point of seven sealings of six gear type one-tenth.This invention is a particular solution of rushing in the sealing region of engagement, and it can make passive output shaft obtain three meshing points and make profile of tooth intensity and monolateral engagement contrast strengthen 3 times, and can obtain zero year journal bearing.
Advantage of the present invention: for six gear counter rotation twin screw extruder moment distributor boxes, it can obtain than the monolateral following 3 times flute profile intensity of the identical condition of the facewidth that is engaged on, this notion is that intensity increases by 50% crash rate and promptly descends 100 times, as seen superiority of the present invention, in the prior art because the gear diameter of twin-screw output shaft is very little, but output torque is relatively large, the force of periphery of profile of tooth engagement can be very big like this, if it can affact and makes its life-span very short and can't bear competent its load on the very little journal bearing of external diameter thereby this force of periphery can not get structural balance.The present invention's zero is carried journal bearing and is supposed it to have 15% precision unbalance loading rate then its life-span can increase (100/15)
3.3=523 times, thus not long contradiction of output shaft journal bearing life-span can thoroughly be solved, and it can replace baroque tapering double screw extruder with the parallel axes counter rotation twin screw extruder by this.
Description of drawings:
Fig. 1 is six gear type counter rotation twin screw extruder moment distributor gear schematic diagrames:
The specific embodiment: describe enforcement preferred plan of the present invention in detail below in conjunction with accompanying drawing
1, active output gear shaft
2, passive output gear shaft.
3, carrier gear
