Description
Technical field
The invention belongs to the pulp and paper industry machinery technical field, especially a kind of novel transmission case of parallel rotary spiral paste mill.
Background technique
Parallel rotary spiral paste mill is a kind of pulping machine of producing paper making pulps with plant fiber material, for the rotation in the same way that realizes twin-screw is rotated, the transmission case of this machine adopts the driving gear of power input shaft to drive the asymmetric drive mechanism (6 gears) of two screw rods axle driven gear respectively by intermediate gear always, perhaps asymmetric pair drive mechanism (10 gears) is to realize the distribution of power.
Along with the increase of parallel rotary spiral paste mill screw diameter and the raising of manufacturing efficiency, require parallel rotary spiral paste mill to have more high pulling torque and Geng Gao rotating speed, the performance of existing transmission case of parallel rotary spiral paste mill is difficult to adapt with it.
The art designs of existing transmission case of parallel rotary spiral paste mill drive mechanism is many, but all exists many problems.By retrieval, some disclosed patents have been found, as " integrated type double screw extruder transmission case " (patent No. is 93203125.0), " a kind of transmission case that is used for double screw extruder " (patent No. is 94225570.4) and " extruder speed reducer " (patent No. is 98225919.0), these several the disclosed technical pattern more complicated of patent, power division is not too reasonable, and drive mechanism is asymmetric; And processing, assembling and detection are inconvenient.
Summary of the invention:
The objective of the invention is to overcome the defective that exists in the prior art, by the remarkable innovation to drive mechanism, it is reasonable to propose a kind of scientific structure design, can satisfy the transmission case of parallel rotary spiral paste mill of high speed, high torque demand.
The present invention realizes that the technological scheme of purpose is:
This transmission case of parallel rotary spiral paste mill, a power input shaft is housed on casing, two idler shafts and two power output shafts, these two power output shafts are connected with two screw rods by coupling respectively, it is characterized in that: be fixed with a driving gear on the power input shaft in casing, this driving gear bilateral symmetry is engaged with two idle pulleys that size is identical, on the idler shaft that these two idle pulleys are installed, all be fixed with two identical driven idle pulleys of size, these two driven idle pulleys mesh two driven gears that size is identical that all are fixed with power output shaft on it, two idler shafts respectively, two power output shafts are arranged on same plane.
And two power output shaft ends in casing all are equipped with the thrust bearing group.
And described two idler shafts, two power output shafts, all idle pulley and the assembling basal plane of bearing overlap with the junction plane of case lid and casing.
And described case lid and casing adopt two cavity configurations.
Remarkable advantage of the present invention and good effect are:
The transmission sports applications of design the basic principle of power dividing, realized that power just begins power dividing from driving gear, and symmetrical transmission, idle pulley on two idler shafts is identical, two driven gears are identical, make design of gears fairly simple, and two idler shaft loads are less.The implication of above-mentioned power dividing basic principle is that the power of two idler shafts and power output shaft transmission equates and be half of input power in transmission case of parallel rotary spiral paste mill.Moment of torsion and stress that the two pairs of idle pulleys bear reduce, and have reduced the dimension volume of idle pulley and idler shaft, have improved their bearing capacity.And the idler shaft of this transmission case of parallel rotary spiral paste mill and power output shaft all on flask joint, make transmission case be easy to processing, assembling and detection.
Description of drawings
Fig. 1 is the structure plan view that removes case lid of the present invention;
Fig. 2 is the gear layout side view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are further described:
The transmission case of parallel rotary spiral paste mill of present embodiment as shown in Figure 1 and Figure 2, whole transmission case is divided into case lid 15 and casing 4, the two is the spiral-lock form, covers by the bolt (not shown) on flask joint 14, and various transmission paries are installed in the transmission case.The outer motor reel (not shown) of casing connects power input shaft 12 by elastic coupling flexible coupling 13, the other end of this power input shaft in casing is fixed with a driving gear 11, this driving gear bilateral symmetry is engaged with two idle pulleys 10 that size is identical, the idler shaft 9 of these two idle pulleys all is packed on the casing, on the idler shaft that these two idle pulleys are installed, all be fixed with two identical driven idle pulleys 5 of size, these two driven idle pulleys mesh the identical driven gear 6 of two sizes that all is fixed with power output shaft 7 on it, these two idler shafts respectively, two power output shafts are arranged on same plane.These two power output shafts are connected with two screw rods 1,2 respectively by coupling 3 outside casing.
End at two above-mentioned power output shafts all is equipped with thrust bearing group 8, is used for bearing when two screw rods rotate the extruding defibrination in the same way the very big axial force that produces.The installation position of power input shaft, power output shaft, idler shaft and casing all is equipped with bearing, and these bearings do not have label.
For the ease of processing, assembling with detect, idler shaft, power output shaft, all idle pulley and the assembling basal plane of bearing and the junction plane of case lid and casing are to locate at grade, are coincidence status, and case lid and casing adopt two cavity configurations, referring to Fig. 1.
Working principle of the present invention is:
The power input shaft drives fixing top driving gear and rotates, this driving gear drives two idle pulleys simultaneously and rotates in the same way, thereby driving idler shaft rotates, make two driven idle pulleys that are fixed on idler shaft rotate in the same way, two driven gears that these two driven idle pulleys drive again on the power output shaft simultaneously rotate in the same way, rotate in the same way thereby drive two screw rods.
The main feature of transmission case of parallel rotary spiral paste mill of the present invention is according to the power dividing principle, and two idler shafts and two driven shafts adopt the symmetric design structure, make designing and calculating simple, and bearing load reduces on idle pulley and the driven gear, and bearing capacity strengthens; The assembling basal plane of two idler shafts and two power output shafts and gear and bearing all overlaps with the junction plane of transmission-case cover and transmission case body, makes transmission-case cover and casing be easy to processing, is convenient to assembling and detects the manufacture cost reduction.
Transmission case of parallel rotary spiral paste mill of the present invention can also be used for the transmission case of homodromal twin-screw extruder in plastics and homodromal double screw extruder of rubber industry and the food industry.
