And input shaft 122 is supported freely by bearing 137 rotations in speed-changing gear box 102.In addition, with input shaft 122 abreast output shaft 124 be supported freely by bearing (omit diagram) rotation.Be fixed on the gear (gear of minor diameter) 120 of the high-speed side of input shaft 122 and low speed side gear (large diameter gear) 126 engagements that are fixed on output shaft 124.
Bottom at these gears 120,126 is provided with oil groove 136.Stockpile a large amount of lubricant oil Oi at this oil groove 136, thereby the bottom of the gear 126 of low speed side is being soaked.Bearing is installed with food tray 138,140 in the bottom of (bearing of output shaft 124 sides: omit diagram) of bearing 137, so that around separately bottom.And, be provided with semi-moon shaped gear with food tray 142, so that cover the periphery of the gear 126 of low speed side.
Secondly, near the structure the gear 120,126 of cooling tubing 132 is described.
Be formed with a plurality of (being 6 in illustrated embodiment) pipe arrangement fixed hole 154 (154A～154F) at fixed plate 134.At this pipe arrangement fixed hole 154, insert the importing pipeline 156 that cooling medium is installed, the derivation pipeline 158 of cooling medium in its part.
The inlet channel of cooling medium (omitting diagram) is connected with the cooling medium importing side end 132In (with reference to Fig. 3,4) of cooling tubing 132 by importing with pipeline 156.On the other hand, the outlet passage of cooling medium (omitting diagram) is connected with the cooling medium derivation side end 132Ot of cooling tubing 132 by deriving with pipeline 158.
Fixed plate 134 up and down direction be formed with a plurality of be used to insert install import with pipeline 156, derive pipe arrangement fixed hole 154 with pipeline 158 (154A～154F).Is H1 from the lower end of fixed plate 134 to the pipe arrangement fixed hole 154C of foot, the height of 154F.Height from the lower end of fixed plate 134 to pipe arrangement fixed hole 154B, the 154E of central authorities is the H2 bigger than H1.Is the H3 also bigger than H2 (H1＜H2＜H3) from the lower end of fixed plate 134 to the height of pipe arrangement fixed hole 154A, the 154D of the topmost part.
Importing is inserted respectively with pipeline 158 with pipeline 156, derivation and is installed in pipe arrangement fixed hole 154 arbitrarily, and is installed by nut 160.In the present embodiment, will derive to insert and be installed in pipe arrangement fixed hole 154C (highly: H1), be installed in pipe arrangement fixed hole 154D (highly: H3) and will import with pipeline 156 insertions with pipeline 158.
In addition, the hole that is positioned at the central lower of fixed plate 134 is the lubricant oil tap hole 162 that is used to discharge oil.And the lubricant oil input hole 144 that is formed on upside cover 106 also is used for maintenance of speed reducer 100 etc.In the running, the cover of being used by the lubricant oil input hole 146 is closed.
At this, the structure of cooling tubing 132 further is elaborated.
In oil groove 136, be equipped with cooling tubing 132.
And, represent the sectional view ((A) cross-sectional view, (B) longitudinal section, (C) front section view) of cooling tubing 132 at Fig. 4, represent the stereogram of cooling tubing 132 at Fig. 5.
At this, " cooling tubing 132 sets abreast with respect to the surperficial Oi1 of the lubricant oil Oi in the speed-changing gear box 102 " is meant flatly to dispose speed-changing gear box 102 as prerequisite with respect to ground (reference level), but be included in when being obliquely installed speed-changing gear box 102 a little with respect to ground, surperficial Oi1 and the cooling tubing 132 of lubricant oil Oi finally become uneven situation.
And " serpentine shape " be meant when specific substantially horizontal is observed, have the position of the flow velocity drastic change of the cooling water in 2 cooling tubings at least, for example, gets rid of the cooling tubing of U font of the position of the flow velocity drastic change that only has 1 cooling water.
In addition, when cooling tubing 132 is observed from substantially horizontal (Fig. 4 (B), (C)) and when observing (Fig. 4 (A)), the cooling tubing 132 that is adapted to immediate at least the upper and lower does not overlap each other.Particularly, cooling tubing 132 is adapted to the rectangular shape that varies in size, so that center on gear 120,126 from the surperficial Oi1 of lubricant oil Oi towards Vertical direction.For example, the 1st layer of cooling tubing 132 by the rectangular shape till being adapted to from position 132A1 to position 132A2 constitutes (with reference to Fig. 5).In addition, the 2nd layer of cooling tubing 132 by the rectangular shape till being adapted to from position 132B1 to position 132B2 constitutes.Similarly, the 3rd layer of cooling tubing 132 by the rectangular shape till being adapted to from position 132C1 to position 132C2 constitutes.About the 4th layer (till), the 5th layer (till) of back layer, the 6th layer (till) similarly, constitute by the cooling tubing 132 that is adapted to rectangular shape from position 132F1 to position 132F2 from the position 132E1 to position 132E2 from position 132D1 to position 132D2.
And the number of plies of cooling tubing 132 of gear 120 of being arranged to high-speed side is more than the number of plies of the cooling tubing 132 of the gear 126 of low speed side.In this embodiment, the number of plies Y2 of the cooling tubing 132 of the gear 120 of high-speed side is 6 levels, is 4 levels with respect to the number of plies Y1 of the cooling tubing 132 of the gear 126 of this low speed side.
Secondly, the effect to speed reducer 100 describes.
The transmission of power of motor is to the input shaft 122 that is linked to motor reel (motor, motor reel: all omit diagram).By input shaft 122 rotation, be fixed on gear 120 rotations of the high-speed side of input shaft 122, and with gear 126 rotations of the low speed side of gear 120 engagements of high-speed side.Thus, the rotation of the gear 126 of low speed side is slowed down with predetermined reduction speed ratio, from output shaft 124 outputs.
And by the setting of food tray 138,140,142, a part and the lubricant oil Oi of bearing 137 (output shaft 124 sides: omit diagram) are close to, so can supply with the lubricant oil Oi of q.s to bearing 137, just can keep sufficient greasy property.In addition, the part of the gear 126 of low speed side is immersed in lubricant oil Oi, so can supply with the lubricant oil Oi of q.s to the gear 126 of low speed side, just can keep sufficient greasy property.
Cooling water from inlet channel flows into flows into by importing with the importing side end 132In of pipeline 156 from cooling tubing 132.If cooling water contacts with lubricant oil Oi by cooling tubing 132, then the cooling water of low temperature can be from the lubricant oil Oi picked-up heat and cooling (temperature is descended) the lubricant oil Oi of high temperature.That is, this cooling water carries out heat exchange by cooling tubing 132 with lubricant oil Oi.Then, cooling water flow is to the derivation side end 132Ot of cooling tubing 132, and flows out to outlet passage by the derivation that is connected with the derivation side end 132Ot of cooling tubing 132 with pipeline 158.
Then, the effect according near the structure the gear 120,126 of cooling tubing 132 is described.
Fig. 6 (A) is the brief configuration figure when cooling tubing 132 is equipped on upside, (B) is the brief configuration figure when cooling tubing 132 is equipped on downside.
Be formed with a plurality of pipeline 158 is used in the installation importing with pipeline 156 and derivation pipe arrangement fixed holes 154 that are used to insert at fixed plate 134 above-below directions.By utilize using the fixed plate 134 of this structure, can move to position (highly) arbitrarily with pipeline 158 with importing according to the diameter of gear, and (highly) sets cooling tubing 132 in position with pipeline 156 and derivation.
For example, when hanging down reduction speed ratio, the diameter of the gear 120 of high-speed side and the gear 126 of low speed side is roughly the same size.(Fig. 6 (B)) is in a ratio of minor diameter (Fig. 6 (A)) when the gear 126 of low speed side and high reduction speed ratio.At this moment, be installed in pipe arrangement fixed hole 154D by importing with pipeline 156 insertions, be installed in pipe arrangement fixed hole 154B and will derive to insert, can set the cooling tubing 132 (distance till from the center of gear 120,126 to the upper end of cooling tubing 132: HA) at upside with pipeline 158.
On the other hand, during high reduction speed ratio, the diameter of the gear 126 of low speed side is compared with the diameter of the gear 120 of high-speed side and is become big (Fig. 6 (B)).Therefore, to import with pipeline 156 insertions and be installed in pipe arrangement fixed hole 154E, and will derive to insert and be installed in pipe arrangement fixed hole 154C, cooling tubing 132 will be provided in downside (Fig. 6 (B)) (distance till from the center of gear 120,126 to the upper end of cooling tubing 132: HB (HA＜HB)) with pipeline 158.Thus, can avoid contacting of gear 120,126 and cooling tubing 132.
By above-mentioned mechanism, can make cooling tubing 132 approach gear 120,126 as far as possible, realize the mechanism of the distance of adjustment cooling tubing 132 relative gears 120,126.
By diameter that changes gear 120,126 or the position that is fixed with the axle 122,124 of gear 120,126, even when need changing the equipping position of cooling tubing 132, utilize this mechanism (mechanism) also can be easily be combined as identical shaped cooling tubing 132 whole with gear 120,126 near or away from.Thus, can seek the optimization of the equipping position of the High Level of the stirring action by gear 120,126 and cooling tubing 132, and the cooling effectiveness of lubricant oil Oi is further improved (carrying out aftermentioned) for detailed content.Its result prevents the deterioration of gear 120,126 or bearing 137 etc., and can use speed reducer 100 for a long time.
And, fixed plate 134 up and down direction be formed with a plurality of pipe arrangement fixed holes 154, so can be a plurality of positions with the position change of cooling tubing 132 with 1 fixed plate 134.Thus, for multiple class speed reducer 100, but common application fixed plate 134.Its result, the shared part that fixed plate 134 be can be used as speed reducer 100 series is made, so manufacture cost, manufacturing process when speed reducer 100 serial whole observations are reduced.
Because cooling tubing 132 is coppers, so have enough heat-conducting propertys.And, form cooling fin 148 made of copper in the periphery of cooling tubing 132, and enlarge the area of contact of lubricant oil Oi and cooling tubing 132.
Cooling tubing 132 sets abreast with respect to the surperficial Oi1 of the lubricant oil Oi in the speed-changing gear box 102, and sets multilayer from this surface Oi1 towards the Vertical direction downside.In addition, cooling tubing 132 is observed from substantially horizontal and is serpentine shape, becomes coiled type.In addition, during speed reducer 100, the cooling tubing 132 that is adapted to immediate at least the upper and lower with respect to the Vertical direction downside does not overlap each other when substantially horizontal is observed.
Thus, it is big that the surface area that lubricant oil Oi is contacted with cooling tubing 132 becomes, so as a whole, the surface area that cooling tubing 132 is contacted with lubricant oil Oi becomes big.Therefore, can further successfully carry out the high-efficiency thermal exchange of cooling water by cooling tubing 132 from the more heat of lubricant oil Oi picked-up.
Cooling tubing 132 sets ((importing the height with pipeline 156)＞(deriving the height with pipeline 158)) from the surperficial Oi1 of lubricant oil Oi towards the Vertical direction downside.That is, cooling tubing 132 is from the surperficial Oi1 side of lubricant oil Oi, more specifically from being provided in the lubricant oil Oi with the nearest position of gear 120,126.Thus, the lubricant oil Oi that becomes gear 120,126 peripheries of the highest temperature in lubricant oil Oi can carry out heat exchange at first with the cooling liquid of not carrying out the lowest temperature of heat exchange.Therefore, in the present embodiment, according to the heat that is taken place, can be with the optimal heat exchange of the power of heat exchange.The locality high-temperature portion does not take place and the temperature of lubricant oil Oi can be made as equalization in its result in lubricant oil Oi.
For the temperature of cooling off equably in this lubricant oil Oi, setting the number of plies and also can replenish towards the cooling tubing 132 of Vertical direction downside from gear 120 sides of high-speed side gear 126 side faces more than low speed side.
According to this structure, the cooling tubing 132 of gear 120 sides of the high-speed side by setting a lot of minor diameters towards the Vertical direction downside, the distance of the foot of cooling tubing 132 and two gears 120,126 can be set as roughly certain, so can be from two gears 120,126 (at the Vertical direction downside) heat that taken place of same position picked-up roughly.And, 120,126 engaging position and gear 120 peripheries of (high speed rotating) high-speed side set more cooling tubing 132 each other in that the gear that the worry that heat uprises takes place is arranged, so with respect to the high position of the heat that is taken place, cooling performance is also strengthened.Thus, the locality high-temperature portion not taking place and can be with the lubricant oil Oi of cooling to integral extension at lubricant oil Oi, and makes the further convergence equably of temperature in the lubricant oil Oi.
And, approaching by the distance that further makes gear 120,126 and cooling tubing 132, utilize the stirring action of gear 120,126, the further expansion in a wide range of lubricant oil Oi with cooling just can make the whipping performance of heat exchange improve.Especially, the gear 120 of (high speed rotating) high-speed side is strong by the stirring action of the lubricant oil Oi that rotating force causes, so the lubricant oil Oi of cooling is further expanded in a wide range, the whipping performance of heat exchange is improved.
Promptly, be set as the distance of the foot of cooling tubing 132 and two gears 120,126 roughly certain, generation heat and stirring action that consideration is caused by the difference of the rotational speed of gear 120,126, by setting cooling tubing 132, the just temperature of cutting oil Oi equably.
In addition, the heat exchange by the phenomenon that cooling tubing 132 is set at gear 120,126 peripheries causes makes between the lubricant oil Oi of bottom surface and produces temperature difference.Its result, its temperature official post produces flow phenomenon in lubricant oil Oi, and the lubricant oil Oi of temperature difference is flowed, so can promote above-mentioned stirring action.
In the present embodiment, the mechanicalness stirring action that is caused by gear 120,126 is assisted the high efficiency stirring action of realizing in the heat exchange mutually with the convection effects according to law of nature.
The effect that its effect and expansion by above-mentioned surface area cause is auxilliary mutually and cooling performance is further improved.
In addition, towards the cooling tubing 132 that the Vertical direction downside sets, the cooling tubing 132 that is adapted to immediate at least the upper and lower does not overlap each other from the surperficial Oi1 of lubricant oil Oi.
Thus, because the cooling tubing 132 of immediate the upper and lower do not contact each other, so lubricant oil Oi can flow to each other at this cooling tubing 132.That is, cooling tubing 132 does not hinder flowing of lubricant oil Oi and the flow velocity of lubricant oil Oi around the cooling tubing 132 accelerates, and above-mentioned stirring efficiency is further risen.Therefore, its effect can make cooling performance further improve.
Promptly, the raising of the flowability of the lubricant oil Oi of Vertical direction downside, not only to adopt stacked cooling tubing 132, and the effect of having only the arrangement of having adopted the related structure of present embodiment to realize, and be for further improving the effective factor of cooling performance.
The ledge structure of the cooling tubing 132 that embodiments of the present invention are related is assisted mutually with the effect based on the mechanism of the distance of adjusting above-mentioned cooling tubing 132 relative gears 120,126, from the surperficial Oi1 of lubricant oil Oi towards the Vertical direction downside, it is big that the surface area that cooling tubing 132 is contacted with lubricant oil Oi becomes, and can seek the raising of whipping performance.Its result can make the cooling capacity of cooling unit further improve.
Promptly, the present invention is not limited to (2 dimension) in the same level with the pattern that sets of cooling tubing 132, consideration can make-up oil Oi the cooling tubing 132 of flowability of smoothness and the position relation of gear 120,126, by also extending to the pattern that sets that short transverse (3 dimension) forms cooling tubing 132, the raising of the significant cooling performance that can't obtain to realize only simple stacked cooling tubing 132.
Prevent the especially bearing 137 of gear 120,126, deterioration of (bearing of output shaft 124 sides: omit diagram) part by the raising of this cooling performance, can realize long-term and service cycle long-term between spreadable life of speed reducer 100.
And, owing to be the inner type of cooling, therefore can seek the miniaturization of speed reducer 100, the reductionization of cooling cost.
As known from the above, by utilizing the present invention, though be the inner type of cooling, cooling performance is high, and its result can seek the miniaturization of speed reducer 100 and the reductionization of cooling cost.
In addition, in the present embodiment, consider the high efficiency of heat exchange, be made as to be higher than to derive and use pipeline, but also can be made as identical with pipeline and derivation with the height of pipeline importing is installed with importing mounting point with pipeline.
In addition, consider heat conductivity and utilized the material of cooling tubing made of copper, but consider corrosivity, heat resistance, also can use other material (for example stainless steel etc.).The internal diameter of cooling tubing is not limited to identical, in order further to improve cooling performance, also can enlarge the external diameter of the cooling tubing of high (high-temperature portion) high velocity layer side of heating.And in the plane on the equal height direction, cooling tubing constitutes rectangular shape, but also can further enlarge the area of contact with lubricant oil Oi by crooked setting as coiled type.The cooling fin that is formed on the cooling tubing periphery considers that its shape or size further enlarge and the area of contact of lubricant oil Oi also can make cooling performance improve.
In the above-described embodiment, owing to imagined the speed reducer that is used for paper machine, therefore used cooling water (water-cooled) as cooling medium (changing easily when the corrosion), but so long as the cooling medium that can play a role as cooling medium then especially do not limited.
By the degree of Rotate 180 up and down that makes fixed plate (the length H1 from the lower end to the pipe arrangement fixed hole that is formed at foot is different parts with length H4 from the upper end to the pipe arrangement fixed hole that is formed at the topmost part) use or change the different pipe arrangement fixed hole in the position that forms short transverse about fixed plate, can further carry out inching easily to the height of cooling tubing according to the size of gear, desired cooling performance.And, introduction hole and leadout hole are formed on the same side of speed-changing gear box, but also both can be formed on different separately sides.Import (derivation) the pipe arrangement fixed hole of insertion is passed through in the position when being provided with height (position) adjustment that is provided with pipeline, but after using, the equipping position that can be adjusted the pipe arrangement of importing (derivation) usefulness by operator's manual regulating mechanism or automatic adjusting mechanism (all omitting diagram) can be set also.
As the gear that is installed in the speed-changing gear box, be not only parallel-axes gears, also can use the present invention in orthogonal gear.And the progression of gear is not limited to the progression of 1 grade of gear-type, even the progression of type also can be used the present invention more than 2 grades.
In addition, though not shown, also the pipe arrangement fixed hole can be made as slotted hole.Thus, need not change to derive mounting point of (importings) usefulness pipeline, so can be more easily and more suitably carry out inching according to the cooling tubing fixed hole.And, can carry out the inching of the equipping position of cooling tubing, so also further expansion of the variation of the speed reducer that can use is many as the shared part change of decelerator series integral body, so can reduce the manufacture cost when the decelerator series whole observation.In addition, so long as can then also can use the pipe arrangement fixed hole is made as slotted hole mechanism in addition to deriving the mechanism that (importing) carries out inching with pipeline.
In the present embodiment, cooling tubing is as one and moulding, but it is a plurality of also cooling tubing to be divided into, and each end of cooling tubing is connected by the connector that can load and unload, and at least 1 support that is arranged on described speed-changing gear box side of connector.Thus, except can obtaining the effect identical, can prevent that also the front end of cooling tubing from distorting, and further easily carry out the assembling of pipe arrangement with above-mentioned mode of execution.Can easily and carry out the replacing of cooling tubing partly when for example having some undesirable condition of cooling tubing corrosion in the device etc., so useful.Support is arranged on the bottom surface of speed-changing gear box in the above-described embodiment, but also can be arranged on other sides of speed-changing gear box.
In addition, in the constituent part that mode of execution is put down in writing, the important document, even do not have part, the important document of special record, if the size of constituent part, material, shape, other relatively configuration etc. do not have special specificity to forbid, this scope of invention neither be only limited to its aim.
