Abstract

The utility model relates to a vertical decelerator sealing structure and a vertical decelerator. The vertical decelerator sealing structure is provided with a decelerator box, a gear and an output shaft. The outer ring of the output shaft is sleeved with an oil isolation ring. The bottom of the oil isolation ring is fixed at the bottom of an inner cavity of the decelerator box. A distance ring is installed between the gear and the shoulder of the output shaft. The top of the oil isolation ring is in sealed connection with the distance ring. The height of the oil isolation ring is larger than the height of the oil level of the inner cavity of the decelerator box. Oil of the inner cavity of the decelerator box is isolated from the output shaft through the oil isolation ring. A shaft sleeve is installed on the outer wall of the output shaft and located below a bearing. A through cover is fixed at the bottom of a bearing seat. Two oil seals arrayed in the vertical direction are arranged between the through cover and the shaft sleeve. The shaft sleeve and inner lips of the oil seals are sealed in a matched mode. As the downward part of the output shaft is completely isolated from lubricating oil of the inner cavity of the decelerator box through the oil isolation ring, the lubricating oil is not prone to leakage through the output shaft.

Technical field
The utility model relates to speed reducer technical field, especially relates 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.
Model utility content
The technical problems to be solved in the utility model 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 utility model solves the technological scheme that its technical problem adopts: 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 the fixing transparent cover in described bearing support bottom, arranges two oil sealings, axle sleeve and the oil sealing inner lip fitted seal that are arranged above and below between transparent cover and axle sleeve.
Further, in described transparent cover, the lubricating cup for laying grease is installed.
A kind of vertical type speed reducer (change gear), has above-mentioned vertical type speed reducer (change gear) sealing configuration.
The beneficial effects of the utility model are: the utility model 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 ensure that grease does not spill easily; Axle sleeve is easily to change part, and when 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.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
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
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
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 transparent cover 6 is fixed in bearing support 5 bottoms, 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.
Lubricating cup for laying grease is installed in transparent cover 6.
A kind of vertical type speed reducer (change gear), has above-mentioned vertical type speed reducer (change gear) sealing configuration.
The utility model 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, when 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;
