Abstract
The invention relates to a vertical reducer seal structure and a vertical reducer. The vertical reducer seal structure comprises a reducer box, a gear, and an output shaft. An oil spacer ring sleeves an outer ring of the output shaft. The bottom of the oil spacer ring is fixed at the bottom of an inner cavity of the reducer box. A distance ring is mounted between the gear and the shoulder of the output shaft. The top of the oil spacer ring is hermetically connected with the distance ring. The oil spacer ring is higher than oil level in the inner cavity of the reducer box. The oil spacer ring isolates oil in the inner cavity of the reducer box and the output shaft. A shaft sleeve is mounted on the outer wall of the output shaft and located below a bearing. An unclosed end cover is fixed at the bottom of a bearing block. Two oil seals arranged from top to bottom are disposed between the unclosed end cover and the shaft sleeve; the shaft sleeve is in hermetic fit with inner lips of the oil seals. The downward portion of the output shaft and lubricating oil in the inner cavity of the reducer box are fully isolated by the oil spacer ring, and lubricating oil rarely leaks from the output shaft.
Description
Technical field
The present invention relates to speed reducer technical field, especially relate to a kind of vertical type speed reducer (change gear) sealing configuration and vertical type speed reducer (change gear).
Background technique
The vertical type speed reducer (change gear) that user uses at present; output shaft down; most of use flooding system lubrication; because output terminal issues bearing and is immersed in all the time in oil, issue by oil sealing sealing, use for a long time Rear oil seal wearing and tearing; output terminal just starts leakage of oil; this leakage of oil situation is seriously perplexing user, once leakage of oil, the loss that shutdown, dismounting, maintenance cause is unable to estimate.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, a kind of vertical type speed reducer (change gear) sealing configuration and vertical type speed reducer (change gear) of not easy oil leakage is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of vertical type speed reducer (change gear) sealing configuration, there is box body of speed reducer, gear, output shaft, described output shaft outer ring sleeve is provided with oil flinger ring, described oil flinger ring bottom is fixed on the intracavity bottom of box body of speed reducer, between described gear and the shaft shoulder of output shaft, distance ring is installed, described oil flinger ring top and distance ring are tightly connected, the height of described oil flinger ring is greater than the level height of decelerating chassis intracoelomic cavity, and described oil flinger ring separates the fluid of cabinets cavity and output shaft.
Further, between described oil flinger ring top and distance ring, form labyrinth seal.
Further, installation shaft bearing between described output shaft and box body of speed reducer outer wall, installs bearing between bearing support and output shaft.
Further, described output shaft outer wall is equipped with axle sleeve, and axle sleeve is positioned at bearing below, and described bearing support bottom is transparent cover fixedly, and two oil sealings, axle sleeve and the oil sealing inner lip fitted seal being arranged above and below is set between transparent cover and axle sleeve.
Further, in described transparent cover, be provided with for laying the lubricating cup of grease.
A vertical type speed reducer (change gear), has above-mentioned vertical type speed reducer (change gear) sealing configuration.
The invention has the beneficial effects as follows: the present invention by oil flinger ring by output shaft down part and decelerating chassis intracoelomic cavity lubricant oil keep apart completely, lubricant oil is difficult to be spilt by output shaft.Axle sleeve and oil sealing inner lip coordinate, and guarantee that grease does not spill easily; Axle sleeve is easily to change part, and after long time running, oil sealing and axle sleeve have wearing and tearing in various degree, only transparent cover need be pulled down together with oil sealing, and axle sleeve heating is pulled down, and replace with spare part, continue to use, and the time is fast, and it is convenient to change.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is structural representation of the present invention;
Wherein: 1, gear, 2, distance ring, 3, oil flinger ring, 4, box body of speed reducer, 5, bearing support, 6, transparent cover, 7, oil sealing, 8, axle sleeve, 9, output shaft.
Embodiment
The present invention is further illustrated by reference to the accompanying drawings now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present invention in a schematic way, so it only shows the formation relevant with the present invention.
As shown in Figure 1, a kind of vertical type speed reducer (change gear) sealing configuration, there is box body of speed reducer 4, gear 1, output shaft 9, output shaft 9 outer ring sleeves are provided with oil flinger ring 3, oil flinger ring 3 bottoms are fixed on the intracavity bottom of box body of speed reducer 4, between gear 1 and the shaft shoulder of output shaft 9, distance ring 2 are installed, and oil flinger ring 3 tops and distance ring 2 are tightly connected, the height of oil flinger ring 3 is greater than the level height of box body of speed reducer 4 inner chambers, and oil flinger ring 3 separates the fluid of cabinets cavity and output shaft 9.Between oil flinger ring 3 tops and distance ring 2, form labyrinth seal.
In Fig. 1, the double dot dash line at oil flinger ring 3 places represents the level height of box body of speed reducer 4 inner chambers.
Installation shaft bearing 5 between output shaft 9 and box body of speed reducer 4 outer walls, installs bearing between bearing support 5 and output shaft 9.
Output shaft 9 outer walls are equipped with axle sleeve 8, and axle sleeve 8 is positioned at bearing below, and bearing support 5 bottoms are transparent cover 6 fixedly, and two oil sealings 7 that are arranged above and below, axle sleeve 8 and oil sealing 7 inner lip fitted seal are set between transparent cover 6 and axle sleeve 8.
In transparent cover 6, be provided with for laying the lubricating cup of grease.
A vertical type speed reducer (change gear), has above-mentioned vertical type speed reducer (change gear) sealing configuration.
The present invention by oil flinger ring 3 by output shaft 9 down part and box body of speed reducer 4 inner chamber lubricant oil keep apart completely, lubricant oil is difficult to be spilt by output shaft 9.
Between gear 1 and output shaft 9 shaft shoulders, increase distance ring 2, between distance ring 2 and oil flinger ring 3, form labyrinth seal, during speed reducer work, distance ring 2 rotates with gear 1, and oil flinger ring 3 keeps static, form effective seal ring, more effectively stop lubricant oil to flow out from gap;
Sealing configuration of the present invention can effectively turn round for a long time, in transparent cover 6, increase and have lubricating cup simultaneously, can regular replenishment grease, output shaft 9 bottoms, by fatten, are lubricated below bearing, because rotating speed is low, grease can meet usage requirement completely, and grease viscosity is high, is difficult for spilling, and output shaft 9 belows are designed with 2 oil sealings 7, can more guarantee that grease does not spill; Assurance bearing runs well.
Axle sleeve 8 and oil sealing 7 inner lips coordinate, and guarantee that grease does not spill easily.
Axle sleeve 8 is easily to change part, and after long time running, oil sealing 7 and axle sleeve 8 have wearing and tearing in various degree, only transparent cover 6 need be pulled down together with oil sealing 7, and axle sleeve 8 heating are pulled down, and replaces with spare part, continues to use, and the time is fast, and it is convenient to change.
The above-mentioned foundation desirable embodiment of the present invention of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this invention technological thought, carry out various change and modification completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to claim scope.
