Description

Large gear case welding casing novel bearing lubricating structure
Technical field
The present invention relates to a kind of box bearing lubricating structure, is a kind of novel bearing lubricating structure of large gear case welding casing specifically.
Background technique
At gear-box middle (center) bearing running hours such as faulty lubrication, bearing is fragile, so the bearing lubrication of gear-box is very important.Gear-box is divided into the cast inblock casing and welds two kinds of casings at present, bearing lubrication method in the cast inblock casing has: a kind of is by cloth oil pipe band lubricating pump bearing to be lubricated, as the patent No. is the gear-box automatic lubricator of CN200520090355.0, oil pump is through the fuel sucking pipe oil suction, send oil to realize lubricated through stop valve, one-way valve, filter and pipeline road to each gear and bearing lubrication point place, the lubricating structure complexity, the user cost height,, promptly can't normally lubricate by lubricating pump maintenance, replacing inconvenience in case damaging gear-box; When being the cast inblock casing, another kind on bearing support, casts out similar oil groove or oily passage is lubricated bearing, as the patent No. is the disclosed gear self-lubricating device for gear box of CN200720032394.4, this gear-box increases a guide plate of casting simultaneously with casing at cabinet wall, on bearing chamber, increase a guiding gutter simultaneously, filler opening and lubricant reservoir, utilize centrifugal force and gravity to collect gearbox medium gear lubricant oil and supply with bearing lubrication, this structure can satisfy the bearing lubrication demand, but cast guide plate simultaneously in casting, guiding gutter, filler opening and lubricant reservoir, casting technique is loaded down with trivial details, produces, the fabricating cost height.
Summary of the invention
Loaded down with trivial details for the complex structure, the casting technique that solve the medium-and-large-sized casting box of prior art casting lubricating fitting, cost of production is high, and in casing, set up the component that lubricating pipe is lubricated various, safeguard inconvenience, the high deficiency of user cost, the invention provides a kind of simple in structure, make, user cost is cheap, easy to maintenance, the large gear case welding casing novel bearing lubricating structure of energy effectively lubricating bearing.
The technical solution used in the present invention is: a kind of large gear case welding casing novel bearing lubricating structure, the welding side plate forms casing on the bearing support, Bearing Installation is in bearing support, its technical characteristics is that the sidewall of described casing inner pedestal welds first baffle plate, and second and third baffle plate of welding forms oil storage tank between the first baffle plate two ends and the box side; Described bearing support is provided with the oil inlet hole that is communicated with the bearing support inner bearing, and first baffle plate upper end exceeds oil inlet hole.
Further, described first baffle plate is straight plate or L template.
Again further, the bearing support upper surface is located in the aperture of described oil inlet hole, or oil inlet hole is made up of oil-feed tank on the casing inner pedestal sidewall and the connection of the oil inlet passage in the bearing support.
After adopting above technological scheme, the beneficial effect that the present invention reaches is: welding formation oil storage tank between first, second and third baffle plate and casing in the gear-box, and lubricating structure is simple, need not additionally set up pipeline or parts, and fabricating cost is low, and is easy to maintenance; When inner gear of the gear box runs up, lubricating oil splash in the casing is to oil storage tank, when first baffle plate is straight plate, straight plate face and box side welding, straight plate face, box side, bearing support upper surface, bearing support madial wall and second and third baffle plate surround oil storage tank and carry out oil storage, and the lubricant oil in the oil storage tank is lubricated to the oil-feed of bearing support inner bearing through the oil inlet hole of bearing support upper surface; When first baffle plate is the L template, the horizontal flanging of L template and box side welding, L template, box side, bearing support upper surface, bearing support madial wall and second and third baffle plate surround oil storage tank and carry out oil storage, and the lubricant oil in the oil storage tank oil-feed tank on the box inside wall, the oil inlet passage in the bearing support successively lubricates the oil-feed of bearing support inner bearing; Lubricant oil is lubricated in oil inlet hole enters bearing by oil storage tank all the time, has guaranteed that bearing is uninterruptedly lubricated.
The present invention adopts the box side of baffle plate and welded gear case to form oil storage tank and stores the lubricant oil that gear splashes, and by the oil inlet hole of bearing support lubricant oil in the oil storage tank is delivered to bearing and realize lubricated, its lubricating structure is simple, easily manufactured, cost is low, easy to maintenance, the pcrmanent lubrication of bearing in the time of guaranteeing gear-box work.
