Abstract
The utility model relates to a sealing structure of a big gear of a ball grinder. The sealing structure comprises a big gear oil groove (1), a gear cover oil groove (2), a sealing gasket (3), felt (4) and a pressing plate (5). The gear cover oil groove (2) is formed in the radial inner ring of the big gear oil groove (1) and extends to the position below the big gear oil groove, and therefore all lubricating oil thrown out by the big gear can be collected. The felt (4) and the pressing plate (5) are sealed flexibly through the sealing gasket (3), and therefore external dust can be prevented from entering a gear cover.
Description
Technical field
The utility model relates to a kind of sealing configuration, especially a kind of ball milling gearwheel sealing configuration.
Background technique
At present, the Edge-Transmission pebble mill using on market, its gearwheel sealing principal mode mainly contains radially packing seal, end face packing seal, but due to the long term wear of filler and gear sealing, between filler and sealing surface, form gap and cause leakage of oil, both wasted lubricant oil, and also had a strong impact on environment, to such an extent as to gearwheel leakage of oil becomes the problem that never has fine solution.
The Edge-Transmission pebble mill using at present, its gearwheel seals main deficiency and mainly contains: gear cover inwall welding oil groove, easily distortion, and in gearwheel finishing bathtray footpath upward, when installation, often interfere, cause installing.In structure: the long-pending oil of gearwheel oil groove can be thrown on gear cover oil groove inner ring in turning course, thereby flow out, cause leakage of oil, affect environment.This technology changes gear cover finishing bathtray position and structure from structure, and gear cover oil groove is designed below gearwheel oil groove, changes bolt into and connects, and can solve installation interference problem again can effective sealing lubricant oil.
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 Gear of Ball Mill sealing configuration, this structure comprises gearwheel oil groove, gear cover oil groove, sealing gasket, felt, pressing plate, sealing structure is first installed gearwheel finishing bathtray, then sealing gasket, gear cover oil groove, felt and pressing plate are installed.In gearwheel turning course, long-pending lubricant oil is thrown to gear cover inwall by gearwheel oil groove, and the oil on inwall flows on gear cover oil groove, and gear cover oil groove extends to below gearwheel oil groove, can collect the lubricant oil that all gear covers flow down, then flow to fuel tank along gear cover oil groove.Felt and pressing plate adopt sealing gasket flexible sealing, can prevent that external dust from entering gear cover.
Wherein, described gear cover oil groove is with bolts.
Brief description of the drawings
Fig. 1 is ball Gear of Ball Mill sealing configuration sectional drawing of the present utility model.
Wherein, 1-gearwheel oil groove, 2-gear cover oil groove, 3-sealing gasket, 4-felt, 5-pressing plate
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
As Fig. 1, Gear of Ball Mill sealing configuration, this structure comprises gearwheel oil groove, gear cover oil groove, sealing gasket, felt, pressing plate, sealing structure is first installed gearwheel finishing bathtray, then sealing gasket, gear cover oil groove, felt and pressing plate are installed.In gearwheel turning course, long-pending lubricant oil is thrown to gear cover inwall by gearwheel oil groove, and the oil on inwall flows on gear cover oil groove, and gear cover oil groove extends to below gearwheel oil groove, can collect the lubricant oil that all gear covers flow down, then flow to fuel tank along gear cover oil groove.Felt and pressing plate adopt sealing gasket flexible sealing, can prevent that external dust from entering gear cover.Gear cover oil groove is with bolts.
The key point of technical solutions of the utility model:
A, gear cover oil groove positions is designed at radially inner ring of gearwheel oil groove, extend under gearwheel oil groove, can collect all lubricant oil that gearwheel throws away.This is simple in structure, without leakage of oil point.
B, felt and pressing plate adopt sealing gasket flexible sealing, can prevent that external dust from entering gear cover.
C, gear cover oil groove are with bolts, are out of shape littlely, and install and adjust is convenient.
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.
Claims (2)
1. a Gear of Ball Mill sealing configuration, it is characterized in that, this structure comprises gearwheel oil groove (1), gear cover oil groove (2), sealing gasket (3), felt (4), pressing plate (5), gear cover oil groove (2) is arranged on radially inner ring of gearwheel oil groove (1), extends under gearwheel oil groove, can collect all lubricant oil that gearwheel throws away, felt (4) and pressing plate (5) adopt sealing gasket (3) flexible sealing.
2. Gear of Ball Mill sealing configuration according to claim 1, is characterized in that, described gear cover oil groove (1) is with bolts.
