Abstract
The utility model relates to a high-speed gear box with an improved structure, which includes a lower box body (1), an upper box body (2), a vent cap (3), blower blades (4), a gear wheel I (5), a gear wheel II (6), a gear wheel III (7), a gear wheel IV (8), an oil pump (9) and an oil baffle plate (10), and is characterized in that input power of the gear box is loaded to the gear wheel II (6); the gear wheel I (5) is mounted on an output shaft; the gear wheel IV (8) is engaged with the gear wheel III (7) on an input shaft, so as to provide power for the oil pump (9); the vent cap (3) with function of oil collection is mounted on the upper box body (2); the oil baffle plate (10) is mounted in the lower box body (1); the oil baffle plate (10) is made of a thin steel sheet uniformly distributed with small holes, and is slightly wider than the tooth width of the gear wheel II (6); and the oil baffle plate(10) can prevent high-temperature lubricating oil from being directly hit on the lower box body (1), so as to produce bubbles and lead to form the overhigh temperature of the gear box.
Description
Technical field
The utility model relates to high-speed gear box, is specifically related to a kind of improved high-speed gear box.
Background technique
The oil pump of tradition high-speed gear box needs exterior power to provide, and has caused the increase of cost and the increase of apparent size, and the motor of increase has also strengthened the loss of electric energy undoubtedly.In addition, the lubricant oil of conventional gearbox can directly beat on casing, caused the increase of gear housing temperature, and direct the beating of lubricant oil have the foam generation on casing, directly had influence on lubrication effect.High-temperature oil gas in the gear-box can directly be discharged in the atmosphere, and the oil droplet that the high-temperature oil gas condensation produces can not in time collect, and has polluted environment.
Summary of the invention
The purpose of the utility model is the shortcoming to traditional high-speed gear box, and a kind of high-speed gear box that improves structure is provided.Main oil pump rotates with main shaft, and when unit turned round in rated speed, main oil pump can be given the gear-box fuel feeding, does not need the additional electric motors oil pump feed, and this greatly reduces the cost to the gear-box fuel feeding, has practiced thrift the energy.Adorned a steel plate with holes at casing internal gear place gear is encased, lubricant oil can not directly be splashed on the casing in the high-speed gear rotation, and is not easy to produce oily foam.Because the temperature of the lubricant oil that high speed rotating brings is very high, so not only reduced the temperature of gear-box overall operation, also improved the lubrication effect of gear-box.Traditional gas permeable devices can only be with exhaust of oil in atmosphere, because temperature is very high in the casing, the oil gas that is discharged in the atmosphere can condensation form oil droplet, and this has caused very big pollution to environment.The utility model is divided into an oil catcher at gas permeable devices, and the oil droplet of condensation is back in the oil catcher, has protected environment.
The technological scheme of the utility model is:
High-speed gear box comprises lower box 1, upper box 2, abat-vent 3, fan blade 4, gear 1, gear 26, gear 37, gear 48, oil pump 9, oil baffle 10, it is characterized in that the input power of gear-box is carried on the gear 26; Gear 1 is installed on the output shaft; Gear 37 engagements on gear 48 and the input shaft, thus oil feed pump 9 provides power; The abat-vent 3 that has the oil-collecting function is installed on the upper box 2; Oil baffle 10 is installed in the lower box 1; Oil baffle 10 is by processing with the sheet metal of even distribution aperture, and the width of oil baffle 10 is bigger slightly than the facewidth of gear 26; Oil baffle 10 can stop the lubricant oil of high temperature directly to be beaten on lower box 1, to cause the gear housing temperature too high, and can prevent that lubricant oil from beating on lower box 1 and produce foam.
The utlity model has following advantage:
1) the improvement cost is low.The utility model is simple to the improvement of traditional high-speed gear box, realize more or less freely, but but can improve the working efficiency of gear-box than the highland.
2) energy-saving and emission-reduction.Main oil pump rotates with main shaft, and when unit turned round in rated speed, main oil pump can be given the gear-box fuel feeding, does not need the additional electric motors oil pump feed, and this greatly reduces the cost to the gear-box fuel feeding, has practiced thrift the energy.
3) lubrication effect improves.Adorned a steel plate with holes at casing internal gear place gear is encased, lubricant oil can not directly be splashed on the casing in the high-speed gear rotation, and is not easy to produce oily foam.Because the temperature of the lubricant oil that high speed rotating brings is very high, so not only reduced the temperature of gear-box overall operation, also improved the lubrication effect of gear-box.

Among the figure, 1. lower box, 2. upper box, 3. abat-vent, 4. fan blade, 5. gear one, and 6. gear two, and 7. gear three, and 8. gear four, 9. oil pump, 10. oil baffle.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 1.
High-speed gear box comprises lower box 1, upper box 2, abat-vent 3, fan blade 4, gear 1, gear 26, gear 37, gear 48, oil pump 9, oil baffle 10, it is characterized in that the input power of gear-box is carried on the gear 26; Gear 1 drives output shaft; Gear 37 engagements on gear 48 and the input shaft, thus oil feed pump 9 provides power; The abat-vent 3 that has the oil-collecting function is installed on the upper box 2; Oil baffle 10 is installed in the lower box 1; Oil baffle 10 is by processing with the sheet metal of even distribution aperture, and the width of oil baffle 10 is bigger slightly than the facewidth of gear 26; Oil baffle 10 can stop the lubricant oil of high temperature directly to be beaten on lower box 10, to cause the gear housing temperature too high, and can prevent that lubricant oil from beating and on lower box, produce foam.
Working procedure
At first oil baffle 10 is fixed on the lower box 1, then the Assembling gear case through two screws.Main oil pump 9 rotates with main shaft, and when unit turned round in rated speed, main oil pump can be given the gear-box fuel feeding, does not need the additional electric motors oil pump feed.When high-speed gear rotated, lubricant oil was beaten on oil baffle 10 earlier, can not directly be splashed on the casing, is not easy to produce oily foam like this, has not only reduced the temperature of gear-box overall operation, has also improved the lubrication effect of gear-box.Ventilative cap 3 makes the oil droplet of condensation be back in the oil catcher, has protected environment.
