Abstract
A novel sealing structure of a gear cover comprises the gear cover (1), a large gear sealing ring (2), a large gear oil groove (3), a large gear (4), a small gear (5), a small gear sealing ring (6), a small gear shaft (7), an oil receiving groove (8) and a small gear oil receiving groove (9). The gear cover (1), the large gear sealing ring (2) and the small gear sealing ring (6) seal the large gear oil groove (3), the large gear (4), the small gear (5), the small gear shaft (7), the oil receiving groove (8) and the small gear oil receiving groove (9). The small gear oil receiving groove (9) is formed in the lower portion of the small gear (5). The oil receiving groove (8) of the whole sealing structure is communicated, according to the novel sealing structure of the gear cover, a sealing mode is changed, lubricating oil is arranged on a sealing face, the phenomenon of oil leakage is avoided, the structure is novel, and effect is obvious.
Description
Technical field
The utility model relates to oven dry, Coolers equipment technical field, is specifically related to a kind of reversible impact sand machine processed.
Background technique
Oven dry, Coolers are a kind of heavy duty equipments that tilts to install and rotate by certain rotating speed, and it is widely used in the every profession and trades such as cement building material, metallurgical mine, chemical industry.Wherein, gearwheel is the vitals of oven dry, Coolers transferring power, and gear cover is sealing gearwheel critical component.Gear cover act as: play foreign matters such as stopping extraneous dust and enter fuel tank; Reclaim the lubricant oil on gearwheel, and prevent that gear lubricant from flowing out gear cover.The quality of gear cover sealing effect, will directly have influence on working life, the consumption of equipment lubrication oil and the running of device security of gearwheel.
As traditional gear cover sealing configuration, comprise following component: gear cover, gearwheel seal ring, gearwheel oil groove, gearwheel, small gear, small gear seal ring, pinion shaft; Its working principle is: the power of motor passes to pinion shaft after the part such as retarder, coupling, and pinion shaft drives small gear, drives the cylindrical shell rotation of Drying and cooling machine after small gear engages with gearwheel.Small gear is in rotary course, and the small gear flank of tooth takes up lubricant oil afterwards and pass to the flank of tooth of gearwheel, forms oil film in large small gear engagement place, thus the lubrication of playing.
Old-fashioned gear cover sealing configuration, in equipment operation process, the parts of lubricating oil above large and small gear is dripped or is splashed on gear cover housing inwall, gearwheel oil groove sealing surface, on pinion shaft sealing surface.Install because of the inclination of equipment, be subject to the impact of gravity, lubricant oil just can be to the trickling of gear cover low side, adds equipment running in 24 hours, and lubricant oil just trickles to the sealing surface of low side continuously: oil groove sealing surface and pinion shaft sealing surface.Equipment does not move several days, and after soft felt wearing and tearing, lubricant oil just flows out gear cover along " oil groove sealing surface and pinion shaft sealing surface ".As a result, after parts of lubricating oil drops on cooling drier body cylindrical, what have trickles after 2～3 meters just to fall on the ground on cylindrical shell periphery.
From above analysis, can find out the shortcoming of old-fashioned gear cover sealing configuration: cause a large amount of gear lubricant to slattern; Contaminated equipment site environment; Increase the workload of workman's lubricating oil filling; Bury the hidden danger (as fire) of device security running.
Model utility content
In order to solve above-mentioned deficiency of the prior art, the utility model proposes a kind of new solution.
A kind of novel sealing structure of gear cover, comprise: gear cover (1), gearwheel seal ring (2), gearwheel oil groove (3), gearwheel (4), small gear (5), small gear seal ring (6), pinion shaft (7), oil-containing groove (8), small gear oil-containing groove (9), gear cover (1), gearwheel seal ring (2), small gear seal ring (6) is by gearwheel oil groove (3), gearwheel (4), small gear (5), pinion shaft (7), oil-containing groove (8), small gear oil-containing groove (9) sealing, small gear oil-containing groove (9) is positioned at small gear (5) bottom, the oil-containing groove (8) of whole sealing configuration is communicated with.Its relevant structural representation refers to Figure of description 1, and this gear cover novel sealing structure changes the sealing surface of " gearwheel seal ring " and " gearwheel oil groove ", increases oil-containing groove; Change pinion shaft sealing means, and increase small gear oil-containing groove.In equipment operation process, the parts of lubricating oil above large and small gear can only drip or splash on gear cover housing inwall, gearwheel oil groove non-tight face.And drippage or the lubricant oil that splashes in gear cover housing inwall is by oil-containing groove, a part enters the oil sump of small gear bottom, and another part flows into small gear oil-containing groove; The parts of lubricating oil that small gear takes up is all connect away the oil sump of rear inflow small gear bottom by small gear oil-containing groove.
This gear cover novel sealing structure, has changed sealing means, and at sealing surface, place does not have lubricant oil, does not certainly just have the phenomenon of leakage of oil, its novel structure, and effect is remarkable.In the equipment of use, solve certainly Drying and cooling machine gear cover oil leak problem completely!

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
A kind of novel sealing structure of gear cover, comprise: gear cover (1), gearwheel seal ring (2), gearwheel oil groove (3), gearwheel (4), small gear (5), small gear seal ring (6), pinion shaft (7), oil-containing groove (8), small gear oil-containing groove (9), gear cover (1), gearwheel seal ring (2), small gear seal ring (6) is by gearwheel oil groove (3), gearwheel (4), small gear (5), pinion shaft (7), oil-containing groove (8), small gear oil-containing groove (9) sealing, small gear oil-containing groove (9) is positioned at small gear (5) bottom, the oil-containing groove (8) of whole sealing configuration is communicated with.Its relevant structural representation refers to Figure of description 1, and this gear cover novel sealing structure changes the sealing surface of " gearwheel seal ring " and " gearwheel oil groove ", increases oil-containing groove; Change pinion shaft sealing means, and increase small gear oil-containing groove.In equipment operation process, the parts of lubricating oil above large and small gear can only drip or splash on gear cover housing inwall, gearwheel oil groove non-tight face.And drippage or the lubricant oil that splashes in gear cover housing inwall is by oil-containing groove, a part enters the oil sump of small gear bottom, and another part flows into small gear oil-containing groove; The parts of lubricating oil that small gear takes up is all connect away the oil sump of rear inflow small gear bottom by small gear oil-containing groove.
The above is only the utility model preferred implementation; should be understood that; for the member of ordinary skill of the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
