Description
[technical field]
The present invention relates to plastic extruder special retarding technical field, is the improvement of prior art ZLYJ type parallel axis hard-tooth surface Special reducer for plastic extruder, a kind of air-cooled plastic extruder dynamic balancing few teeth difference speed reducer.
[background technique] prior art ZLYJ plastic speed reducer special for extruder, be ZLY type two-stage parallel axis hard-tooth surface gear reducer thrust-bearing is set, in order to bear the improvement type of plastics machine screw axial power, be the largest domestic speed reducer Guo Mao of private enterprise speed reducer group in the main product of 2010.6 releases, company claims: " ZLYJ plastic speed reducer special for extruder has that volume is little, bearing capacity is high, stable drive, noise are low, efficiency high." according to speed reducer industry statistics, ZLYJ plastic speed reducer special for extruder, is one of special reduction gear product that the existing Domestic market Accounting amount of having is maximum, imitation producer is maximum.
Research discovery, there is following two large problems in ZLYJ plastic speed reducer special for extruder:
(1) in the plastic barrel that speed reducer front end connects, screw rod, in the condition of high temperature, causes oil temperature in decelerating chassis to rise, thereby the oily circulating cooler of pressure must be set, so that additionally increased manufacture cost and increased complete machine weight;
(2) the lightweight degree of the driving of parallel axes is lower than Gear Planet Transmission, and Gear Planet Transmission comprises planet and the large class of few teeth difference (involute and cycloid) two.The theoretical explanation that Gear Planet Transmission lightweight degree is high sees following authoritative monograph:
(1) < < gear handbook > > (1-4 page): " Gear Planet Transmission has substituted a collection of parallel axes structure driven form; this is because Gear Planet Transmission adopts several planet wheels transfer charges simultaneously; and utilized the combining form of interior engagement, thereby there is the advantages such as bearing capacity is high, volume is little, lightweight, efficiency is high, noise is little.”
(2) Zhu's filial piety record < < Gear Transmission Design handbook > > is 660 pages: " Gear Planet Transmission is compared with fixed shaft gear train, has that volume is little, lightweight, gear range is large, efficiency is high and the advantage such as stable working.Gear Planet Transmission has substituted a collection of parallel axes structure driven form, this is because Gear Planet Transmission adopts several planet wheels transfer charge simultaneously, and utilized the combining form of interior engagement, thereby there is the advantages such as bearing capacity is high, volume is little, lightweight, efficiency is high, noise is little.”
(3) face is thought strong < < involute planet gear driven Design and is manufactured > >: " involute planet gear transmission is compared with common fixed axis gear transmission, there is bearing capacity large, volume is little, efficiency is high, lightweight, noise is little, reliability is high, life-span is long, be convenient to the advantages such as maintenance, ... the casing of Gear Planet Transmission than the casing of common fixed axis gear transmission under similarity condition, it is little several times that its weight is wanted, because planet cage body overall sizes is little more a lot of than the casing of common fixed axis gear transmission.”
Background technique is pointed out, improve the speed reducer dedicated lightweight degree of plastic extruder, the driving of parallel axes of prior art must be improved to Gear Planet Transmission.The calculated example of 7-126 page on < < gear handbook > >: planetary gear train with a small tooth difference efficiency eta=0.944 (two teeth difference Z
d=2); The inventor is according to 100 examples (tooth difference Z
d=2,3,4) calculating, draws following result: efficiency eta=0.934 (Z
d=2), 0.96 (Z
d=3), 0.97 (Z
d=4).Involute Small Teeth Difference Planetary Gearing technical characteristics is known completely for those skilled in the art, and prior art ZLYJ speed reducer special for extruder reduction speed ratio little (i=16) therefore adopts Z
d=4 can obtain high transmission efficiency: η=0.97., thereby single-stage involute less tooth difference can replace the transmission of background technique secondary parallel-axes gears.
Attached: Reducer With Involute Gear of Less-tooth Difference of the present invention and prior art ZLYJ type speed reducer profile and weight comparison sheet
Four planetary gear structures " remarkable advantage is: both sides ring flat-plate uniform thickness, and because both sides ring flat-plate and middle two ring flat-plate phase angles differ 180 °, thereby can realize under dynamic equilibrium state and turning round, transmission is steady especially." (project of national nature science fund project that < < Dual-motors Driving double-crank Fourth Ring board-like pin pendulum Gear Planet Transmission research > > Dalian University Of Communications bears, fund approval number: 50175011)
The technological means of implementing:
An axial fan F is equipped with in described casing side, and the air outlet window P that an exhaust air rate can regulate is equipped with at casing top;
On the end face of described casing output terminal, connect built-in cylinder flange, a side of described built-in cylinder band radiating fin forms the cooling cavity of air-flow in casing and between casing, and it is placed in the barrel of the cylinder end face connection plastic extruder outside casing;
Described built-in cylinder input end end face connects cylinder end cap, the input end cylindrical of described cylinder end cap and casing input end endoporus close-fitting, described cylinder end cap input end face connects with same circle ring disk with the nose circle face of casing input end, makes the freely supported structure of built-in cylinder in two-side supporting;
Described planet wheel is four wheels that parameter is identical, phase place differs, and wherein: both sides planet wheel phase place is identical, middle two planet wheel phase places are identical, 180 ° of both sides planet wheel and middle two planet wheel phase differences;
Described ring gear is fastened on the input end endoporus of built-in cylinder.
[beneficial effect] each independent technical characteristics is supported each other, and can be produced the useful technique effect known to those skilled in the art:
(1) have that bearing capacity is large, volume is little, efficiency is high, noise is little and be convenient to the advantages such as maintenance;
(2) calculate and show: lightweight 40-55%; (3) air cooling structure is simple, and reliability is high, low cost of manufacture.
[summary of the invention] the object of the invention is to provide with air-cooled alternative forced oil cooling radiator cooler to reduce manufacture cost, to replace the existing ZLYJ driving of parallel axes by the planetary drive with small teeth difference of multiple tooth engagement, a kind of air-cooled plastic extruder dynamic balancing few teeth difference speed reducer.
For achieving the above object, its implementer's case and theoretical foundation are as follows:
The present invention take modern Involute Small Teeth Difference Planetary Gearing as basis, and the common practise such as the powerful cooling heat dissipation of combined axis flow type fan, connecting mode, have formed the present patent application claim required for protection.The theoretical foundation of axial-flow blower cooling technology:
972 pages of < < Gear Transmission Design handbook > > point out: " plane table thermoconductivity meter relative volume and surface radiating area greatly reduce; because temperature of equilibrium is still very high; the bearing capacity Power Limitation of being heated ... take auxiliary cooling heat radiator to improve thermal power.”
