Abstract
The utility model discloses a liquid level adjustment oil tank for a gear box. An oil tank opening is formed in the top of the adjustment oil tank, a fixing hole is formed in the side wall of the top of the adjustment oil tank, the liquid level adjustment oil tank is fixed in the gear box through the fixing hole, an oil outlet pipe is arranged at the bottom of the adjustment oil tank, and the lower portion of the oil outlet pipe exactly faces a lubricating hole of a bearing of a gear box transmission device. The adjustment oil tank is in a flat cuboid shape, the cross section of the bottom of the adjustment oil tank is arc or conical, and the oil outlet pipe is arranged at the lowest position of the bottom of the adjustment oil tank. Due to the fact that the area of the oil tank opening of the adjustment oil tank is larger, and the quantity of received lubrication oil is larger than that of discharged oil of the oil outlet pipe, so that in the working process of the gear box, splashed lubrication oil can be filled into the adjustment oil tank. Therefore, the lubrication oil liquid level in the gear box can be effectively reduced, therefore, the condition of bearing lubrication is improved, the oil seal effect is improved, the service life of the lubrication oil and the service life of the bearing can be prolonged, and the liquid level adjustment oil tank is simple in structure, low in cost and good in effect.
Description
Technical field
The present invention relates to a kind of lubricating fitting of actuating unit, say exactly a kind of lubricating fitting of gear-box.
Background technique
For horizontally-mounted gear-box, according to the working speed of the linear velocity of working gear and bearing, determine lubricating system.Relatively good for sealing, rotating speed is higher, and load is large, and what closed performance was good can use gear oil lubricated.Thereby most of gear-box meets flooding system lubrication condition, lubricant oil liquid level will guarantee that three rollers of minimum bearing are immersed in oil.
Once and gear-box works together, the rotating speed of input shaft is higher, generally at 1000rpm between 1500rpm, stir oil very strong, 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, also there is no the liquid level regulation device under gear-box working state.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of liquid level regulating oil tank for gear-box, this device can effectively solve gear while normally working because liquid level rises, cause churning loss 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 is dipped in oil and makes 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 utility model, 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 lubrication hole of the upright bearing to 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 of regulating oil tank bottom.
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 splashing is in a large number received by regulating oil tank mouth, and within being stored in regulating oil tank, then the bearing of supplying with continuously transmission device by oil outlet tube is to provide continuous lubrication.Because the reservoir port area of regulating oil tank is larger, the oil mass of the lubricant oil receiving is greater than the oil mass that oil outlet tube is discharged, so can store up the lubricant oil completely splashing in regulating oil tank in gear-box working procedure.Like this, can effectively reduce the lubricant oil liquid level in gear housing, thereby reach, improve bearing lubrication condition, improve oil sealing sealing effect, extend the working life of lubricant oil and bearing.And the utility model is simple in structure, cost is low, effective.

Description of reference numerals
1-fixed hole; 2-regulating oil tank; 3-oil outlet tube; 4-reservoir port.
Embodiment
Engaging accompanying drawing is below described in further detail the utility model.
Index map 1 is known, and the top of a kind of liquid level regulating oil tank 2 regulating oil tanks 2 for gear-box of the present utility model is reservoir port 4; The sidewall at regulating oil tank 2 tops 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; The lubrication hole of the bearing of 3 times Founders of oil outlet tube to gearbox drive device.
Regulating oil tank 2 is 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 of regulating oil tank 2 bottoms.
The utility model can adopt multiple regulating oil tanks 2 to be arranged on the position of liquid level top near bearing top lubrication hole, when gear-box is worked, have in a large number and lubricate in gear case body and splash, regulating oil tank 2 is collected in parts of lubricating oil in regulating oil tank 2 by reservoir port 4, more slowly flows back in the lubrication hole of bearing from the oil outlet tube 3 of bottom.
The speed that regulating oil tank 2 is got rid of oil-feed is greater than the rate of outflow of regulating oil tank 2 bottom oil outlet tubes 3, and the oil level in regulating oil tank 2 will rise, until regulating oil tank 2 is filled.Like this, the part oil that causes liquid level to rise during gear-box work is just temporarily left in regulating oil tank 2, can make gear-box be in the minimum liquid level that guarantees lubricating status always.Like this, can effectively reduce the lubricant oil liquid level in gear housing, thereby reach, improve bearing lubrication condition, improve oil sealing sealing effect, extend the working life of lubricant oil and bearing.
The contrast of two experimental states below
With FLENDER H3SH16A-31.5 speed reducer, calculate, when motor speed 1500rpm, gear-box output power is 450KW, and 30 ℃ of ambient temperatures adopt mineral oil VG320, and while adopting flooding system lubrication, every content-data contrast is as follows:
| Numbering | Relatively content | Do not install the liquid level regulating oil tank of gear-box additional | Install the liquid level regulating oil tank of gear-box additional |
| １ | Total losses | 19.05KW | 18.06KW |
| ２ | Total efficiency | 95.77% | 95.99% |
| ３ | Gear engagement loss | 11.51KW | 11.22 |
| ４ | Bearing loss | 5.09KW | 4.67KW |
| ５ | Shaft seal frictional loss | 0.16KW | 0.16KW |
| ６ | Churning loss | 2.29KW | 2.00KW |
Above embodiment is not done any pro forma restriction to the utility model; if do not departing within the scope of technical solutions of the utility model; utilize technology contents that this utility model discloses to do local equivalence of changing or modify and implement, all still belong to protection domain of the present utility model.
