Abstract
The invention discloses a liquid level adjusting oil tank for a gearbox. The top of the adjusting oil tank is provided with an oil tank port; a side wall on the top of the adjusting oil tank is provided with a fixing hole; the liquid level adjusting oil tank is fixed in the gearbox through the fixing hole; an oil outlet pipe is arranged at the bottom of the adjusting oil tank; the lower side of the oil outlet pipe is over against the lubricating hole of a bearing of a gearbox transmission device; the adjusting oil tank is in the form of a flat cuboid; the bottom section of the adjusting oil tank is arc-shaped or conical; the oil outlet pipe is arranged at the lowermost position of the bottom of the adjusting oil tank. The area of the oil tank port of the adjusting oil tank is large, and the amount of received lubricating oil is greater than the amount of oil discharged from the oil outlet pipe, so that the adjusting oil tank is full of splashing lubricating oil during working of the gearbox. The liquid level of lubricating oil in a gearbox body is lowered effectively, so that the bearing lubricating condition is improved, the oil seal sealing effect is enhanced, and the service lives of the lubricating oil and the bearing are prolonged. Moreover, the liquid level adjusting oil tank is simple in structure, is low in cost, and has a good effect.
Description
Technical field
The present invention relates to a kind of lubricating fitting of actuating unit, precisely a kind of lubricating fitting of gear-box.
Background technique
For horizontally-mounted gear-box, according to the linear velocity of working gear and the working speed determination lubricating system of bearing.Relatively good for sealing, rotating speed is higher, and load is large, and what closed performance was good can use gear oil to lubricate.Thus, most of gear-box meets flooding system lubrication condition, and lubricant oil liquid level will ensure that three rollers of minimum bearing are immersed in oil.
And gear-box is once work together, the rotating speed of input shaft is higher, and generally between 1000rpm to 1500rpm, stir oil strongly, liquid level can rise obviously.Because liquid level rises, cause churning loss to increase, bearing heating amount increases, and then causes lubricant oil temperature rise increase to make lubricant oil accelerate to lose efficacy.Shaft seal is dipped in oil and makes sealing difficulty, more easily occurs oil leakage phenomenon.
At present, the liquid level regulation device under gear-box working state is not also had.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of liquid level regulating oil tank for gear-box, this device can effectively solve when gear normally works because liquid level rises, churning loss is caused to increase, bearing heating amount increases, and then cause lubricant oil temperature rise increase to make lubricant oil accelerate to lose efficacy, and shaft seal be dipped in oil make sealing difficulty, more easily there is the problem of leakage of oil.
For solving the problems of the technologies described above, a kind of liquid level regulating oil tank for gear-box of the present invention, the top of regulating oil tank is reservoir port; The sidewall at regulating oil tank top is provided with fixed hole, and liquid level regulating oil tank is fixed in gear-box by fixed hole; The bottom of regulating oil tank is provided with oil outlet tube; The upright lubrication hole to the bearing of gearbox drive device under oil outlet tube.
Regulating oil tank is flat cuboid shape, and the cross section of the bottom of regulating oil tank is arc or vertebra shape, and oil outlet tube is arranged on the lowest part bottom regulating oil tank.
The regulating oil tank of this device is fixed on the bearing portion top of gear housing inner driver by fixed hole.Gear-box duration of work, its lubricant oil splashed in a large number is received by regulating oil tank mouth, and is stored within regulating oil tank, then the bearing being supplied transmission device by oil outlet tube is continuously to provide continuous lubrication.Because the reservoir port area of regulating oil tank is comparatively large, the oil mass of the lubricant oil received is greater than the oil mass of oil outlet tube discharge, so can store up the full lubricant oil splashed in regulating oil tank in gear-box working procedure.Like this, the lubricant oil liquid level in gear housing can be effectively reduced, thus reach and improve bearing lubrication condition, improve oil sealing sealing effect, extend the working life of lubricant oil and bearing.And structure of the present invention is simple, cost is low, effective.

Embodiment
The present invention is further detailed explanation for connection with figures below.
Index map 1 is known, and the top of a kind of liquid level regulating oil tank 2 regulating oil tank 2 for gear-box of the present invention is reservoir port 4; The sidewall at regulating oil tank 2 top is provided with fixed hole 1, and liquid level regulating oil tank 2 is fixed in gear-box by fixed hole 1; The bottom of regulating oil tank 2 is provided with oil outlet tube 3; Oil outlet tube 3 times Founders are to the lubrication hole of the bearing of gearbox drive device.
Regulating oil tank 2 is in flat cuboid shape, and the cross section of the bottom of regulating oil tank 2 is arc or vertebra shape, and oil outlet tube 3 is arranged on the lowest part bottom regulating oil tank 2.
The present invention can adopt multiple regulating oil tank 2 to be arranged on the position of close bearing top lubrication hole above liquid level, have a large amount of lubrication to splash in gear case body when gear-box works, parts of lubricating oil is collected in regulating oil tank 2 by reservoir port 4 by regulating oil tank 2, more slowly flows back in the lubrication hole of bearing from the oil outlet tube 3 of bottom.
Regulating oil tank 2 is greater than the rate of outflow of oil outlet tube 3 bottom regulating oil tank 2 by the speed of getting rid of oil-feed, and the oil level in regulating oil tank 2 will rise, until regulating oil tank 2 is filled.Like this, the part oil causing liquid level to rise during gear-box work is just temporarily left in regulating oil tank 2, and gear-box can be made to be in the minimum liquid level ensureing lubricating status always.Like this, the lubricant oil liquid level in gear housing can be effectively reduced, thus reach and improve bearing lubrication condition, improve oil sealing sealing effect, extend the working life of lubricant oil and bearing.
Here is the contrast of two experimental states
Calculate with FLENDER H3SH16A-31.5 speed reducer, as motor speed 1500rpm, gear-box output power is 450KW, ambient temperature 30 DEG C, adopts mineral oil VG320, and when adopting flooding system lubrication, every content-data contrast is as follows:
Above embodiment not does any pro forma restriction to the present invention; if do not departing within the scope of technical solution of the present invention; the equivalence utilizing the done local of this disclosed technology contents to change or to modify is implemented, and all still belongs to protection scope of the present invention.
