Abstract
The utility model relates to a vertical type speed reducer (change gear) with sealed lubricating structure, including speed reducer housing, pump oil device, input shaft and output shaft, set up down the end bearing between output shaft and speed reducer housing's the bottom, inner chamber bottom at speed reducer housing is the oil bath, pump oil device passes through each lubrication points that the speed reducer was carried to the lubricating oil of oil pipe in with the oil bath, spacer spacer outside and in the cover has on the output shaft, outer spacer is fixed on the output shaft, the bottom mounting of interior spacer is bottom speed reducer housing's inner chamber, the top of interior spacer is higher than the liquid level of oil bath, the top of spacer in outer spacer and interior spacer cover through the crisscross mode that sets up. The beneficial effects of the utility model are that: carry out force -feed lubrication through pump oil device, improved lubricated effect, because the inside gear of speed reducer does not soak in lubricating oil, can not produce the resistance, do not influence transmission efficiency. And through adopting inside and outside spacer to keep apart the contact of lubricating oil and oil blanket completely, reach the phenomenon of thoroughly getting rid of seepage oil.
Description
Technical field
This utility model relates to a kind of vertical type speed reducer (change gear) having and sealing lubrication system.
Background technology
The lubrication of current vertical type speed reducer (change gear) adopts bath lubrication, seals and generally uses nitrile rubber oil sealing sealing again.Bath lubrication is to be full of gear oil inside reductor, and its shortcoming is to produce very big resistance when high-speed gear operates, and makes the operational efficiency of reductor be substantially reduced.And, nitrile rubber oil sealing sealing is owing to rubber oil sea to certain lifetime can aging follow the string to such an extent as to completely loses sealing function.
Utility model content
The technical problems to be solved in the utility model is: provides a kind of vertical type speed reducer (change gear) having and sealing lubrication system, improves lubrication and seal effect.
This utility model solves its technical problem and be the technical scheme is that a kind of vertical type speed reducer (change gear) having and sealing lubrication system, including reducer shell and the power shaft and the output shaft that are arranged on reducer shell top and bottom, bottom end bearing is set between output shaft and the bottom of reducer shell, also include oil pumping device, intracavity bottom at reducer shell is oil sump, lubricating oil in oil sump is transported to each oil site of reductor by oil pumping device by oil pipe, output shaft is cased with inner spacing collar and outer separator, outer separator is fixed on output shaft, the bottom of inner spacing collar is fixed on the intracavity bottom of reducer shell, the top of inner spacing collar is higher than the liquid level of oil sump, lubricating oil in oil sump and output shaft are isolated, outer separator and inner spacing collar cover the top of inner spacing collar by the mode being crisscross arranged.
Limiting further, bottom end bearing is lubricated by extreme pressure grease.
Limiting further, be additionally provided with oil sealing between output shaft and the bottom of reducer shell, oil sealing is in the lower section of bottom end bearing.
Limiting further, oil pumping device is electric oil pump, and electric oil pump is arranged on the side of reducer shell, and oil site is positioned at the top of reducer shell.
The beneficial effects of the utility model are: by oil pumping device to reductor each oil site forced feed lubrication respectively, improve lubricant effect, owing to reductor internal gear is not immersed in lubricating oil, will not produce resistance, not affect the transmission efficiency of reductor.And contacting by the lubricating oil in the completely isolated reductor of outer separator in adopting and oil sealing, reach thoroughly to get rid of the phenomenon of leakage of oil.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, this utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. reducer shell in figure, 2. power shaft, 3. output shaft, 4. bottom end bearing, 5. oil pipe, 6. lubricating oil, 7. inner spacing collar, 8. outer separator, 9. oil sealing, 10. electric oil pump.
Detailed description of the invention
As shown in Figure 1, a kind of have the vertical type speed reducer (change gear) sealing lubrication system, including reducer shell 1, oil pumping device and the power shaft 2 and the output shaft 3 that are arranged on reducer shell 1 top and bottom, arranging bottom end bearing 4 and oil sealing 9 between the bottom of output shaft 3 and reducer shell 1, oil sealing 9 is in the lower section of bottom end bearing 4.Bottom end bearing 4 is lubricated by extreme pressure grease, grease seepage hardly itself.
Intracavity bottom at reducer shell 1 is oil sump, oil pumping device down drains back to oil sump after the lubricating oil 6 in oil sump being transported to each oil sites such as the bearing of reductor, gear by oil pipe 5, oil site is positioned at the top of reducer shell 1, i.e. the upper end cover of reducer shell.Each oil site thus can be made to be lubricated fully, be also avoided that gear is immersed in fluid thus gear is produced resistance simultaneously, the transmission efficiency of whole reductor is not affected.Oil pumping device is electric oil pump 10, and electric oil pump 10 is arranged on the side of reducer shell 1.
Output shaft 3 is cased with inner spacing collar 7 and outer separator 8, outer separator 8 and output shaft 3 are fixed as one, common operating, the bottom of inner spacing collar 7 is fixed on the intracavity bottom of reducer shell 1, the top of inner spacing collar 7 is higher than the liquid level of oil sump, thus the lubricating oil 6 in oil sump and output shaft 3 being isolated, outer separator 8 and inner spacing collar 7 cover the top of inner spacing collar 7 by the mode being crisscross arranged.Make lubricating oil can not leak oil sealing 9 place to bottom end bearing 4 and quality of rubber materials.
For various agitators create good effect in this vertical type speed reducer (change gear) reality, from actually used, occur that conventional oil bath lubrication and rubber oil sea seal and have that efficiency is low and the phenomenon of leakage of oil hardly.
