Abstract
The utility model relates to a lubrication structure for a thin seam large-dip-angle coal cutter cutting part. A gear cavity (6) of a second-level reduction gear and a third-level reduction gear is provided with a first gear (1) and a second gear (2) respectively, a lubrication pump (3) is installed in the gear cavity (6), an oil inlet (5) of the lubrication pump (3) is located in the upper portion of the gear cavity (6), and an oil outlet (4) of the lubrication pump (3) is located in the lower portion of the gear cavity (6). Because lubrication oil of the lubrication structure is self-sufficient and achieves circulation, the task of gear lubrication in the large dip angle working process can be finished on the premise of not affecting normal operation of other gear cavities, and normal transmission of the gears is fully guaranteed.
Description
Technical field
The utility model relates to a kind of lubricating structure of girdle large inclined angle winning machine cutting part.
Background technique
When at present low seam mining machinery cutting portion (hereinafter to be referred as cutting portion) is applied to large inclination working surface, there are the following problems: because working surface inclination angle is larger, the gear lubricant in winning machine cutting part gear cavity can be inclined to the one side that relative level face is lower because of the effect of gravity.And the lubricating system of most of cutting portion gear is lubricated by lubricating oil splash, this just very likely occurs in the time that cutting portion is operated in large inclination working surface, some gears are subject to the restriction of structure and can not get lubricated fully, as shown in Figure 1, in the time that working surface inclination angle is larger, first order reduction gear chamber is due to structural relation, lubricating of gear is substantially unrestricted, and the second level, the gear cavity (6) that the third level is slowed down has very serious problem: when working surface favours cylinder one side, lubricant oil in gear cavity (6) is because the effect of gravity all can concentrate on the second gear 2 sides, and only splash by gear oil, just be difficult to guarantee the sufficient lubrication of the first gear 1, in like manner, when working surface favours motor side, the lubricant oil in this gear cavity is concentrated in the first gear 1 place, and only ensures by splash lubricated being also difficult to of the second gear 2 of gear oil, this with regard to serious impact the working life of gear, the working life of even whole cutting portion.
Summary of the invention
The purpose of this utility model is to provide one and is not subject to structure influence, the lubricating structure of the girdle large inclined angle winning machine cutting part to gear sufficient lubrication.The technical solution of the utility model is: a kind of girdle large inclined angle winning machine cutting part lubricating structure, the first gear (1), the second gear (2) are installed respectively in the gear cavity (6) of the second level and third level reducing gear, lubricant pump (3) is installed in gear cavity (6), the filler opening (5) of lubricant pump (3) is positioned at the top of gear cavity (6), and lubricant pump (3) oil outlet (4) is positioned at gear cavity (6) bottom.
The utility model adds a little lubricant pump in needs improve lubricated gear cavity, transmission shaft with suitable rotational speed drives, and divide by the filler opening of lubricant pump and oil outlet the two ends that are placed on this gear cavity, allow this pump inhale this gear cavity with respect to the lubricant oil of ground low spot (in the time that large inclination working surface is worked, the one side of lubricant oil tendency), and oil outlet needs special treatment on lubricated gear while being placed on large inclined angle in this gear cavity, so just allow this gear cavity inside form self-centered oil circulation, do not affecting under the prerequisite of other gear cavity internal gears uses, while greatly having improved large inclination working surface, the lubrication problem of gear.If working surface tilts to other direction, only need to adjust the position of hydraulic fluid port and filler opening, can realize lubricated object, but necessarily be noted that this oil outlet and filler opening can only, in same gear cavity, circulate otherwise just cannot form self-centered gear oil.What the utility model lubricant pump 3 was inhaled is the oil of own oil sump, again to oneself oil sump fuel feeding, just the oil outlet end of oil return just in time by especially need to be lubricated gear, lubricant oil again can be self-sufficient simultaneously, form circulation, so just can be under the prerequisite that ensures not affect the normal work of other gear cavities, the gear lubrication task while completing large inclined angle work, thus fully ensure the normal transmission of gear.
