Abstract
The utility model discloses an oil return device of a gearbox of a rolling mill. The key is that the oil return device comprises a base oil return box arranged at the lower part of the gearbox of the rolling mill, wherein a lower oil return pipe is arranged at the bottom of the gearbox of the rolling mill; an oil return hole is formed in the upper part of the base oil return box; the bottom oil return pipe of the gearbox is inserted into the oil return hole; a lateral oil return pipe is arranged at one side of the base oil return box; and the upper surface of the lateral oil return pipe is lower than the lower bottom surface of the gearbox. For one hand, the oil return device of the gearbox of the rolling mill can be used as a middle oil return box to return oil rapidly and fully, isolate oil return heat energy and abrade filings, and radiate heat rapidly, so that a significant function is played on a high-speed gearbox; and for the other hand, the oil return device of the gearbox of the rolling mill can be used as a mounting base of the gearbox, and the gear in the gearbox can be placed at the bottom as close as possible to the box body, the gear in the gearbox can be placed at the bottom as close as possible to the box body to reduce the gravity of the gearbox body, so that positive function on vibration reduction of the gearbox, especially the high-speed gearbox is played.
Description
Technical field
The utility model relates to a kind of oil return apparatus of gear-box.
Background technique
For improving the gear life of gear-box, existing milling train gear-box, particularly the mode of thin oil spray lubrication is generally adopted in the gear lubrication of fast mill gear-box, so that gear obtains sufficient lubrication, and take away the heat of generation fast, therefore require oil return can flow out casing fast, oil return is totally abundant.And generally adopting the side to install back oil pipe, present gear-box carries out oil return, often residual lubricant oil can be formed on the bottom, oil return is insufficient, on the one hand, accumulate a part of heat in casing, the wearing and tearing iron that also may cause the gear rotation to roll in the residual lubricant oil is on the other hand cut the wearing and tearing of accelerating gear.
The model utility content
The purpose of this utility model provides a kind of milling train gear-box oil return apparatus, makes the gear-box oil return abundant fast, avoids the accumulation of the heat that oil return freely do not cause and the wearing and tearing of gear etc., improves gear life, and is applicable to high-speed gear box.
To achieve these goals, by the following technical solutions: a kind of milling train gear-box oil return apparatus is characterized in that: described device comprises the base oil sump tank that is arranged at the milling train lower gearbox portion
,Wherein the base oil sump tank is the mounting base of milling train gear-box, be provided with the bottom return tube in the bottom of milling train gear-box, base oil sump tank top has spill port, gear-box bottom return tube inserts in the spill port, side at the base oil sump tank is provided with the side return tube, and the upper surface of side return tube is lower than the bottom surface of gear-box.
The inside of described base oil sump tank is provided with the oil return cavity, and chamber outer surface is provided with the gusset that increases heat diffusion area.
The utility model has two effects, is used for as middle oil sump tank on the one hand, and play fully oil return fast, isolation oil return heat and wearing and tearing iron and cut, and the effect of quick heat radiating, this is particularly important to high-speed gear box; On the other hand, itself also is used for the mounting base as gear-box.In addition, oil sump tank in the middle of base is set to, the gear in the gear-box can be positioned over as far as possible near bottom half so, plays the effect that reduces the gear housing center of gravity, this also to gear-box particularly high-speed gear box reduce vibration and play positive role.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Also by reference to the accompanying drawings the utility model is described in further detail below by embodiment.
As shown in Figure 1, a kind of milling train gear-box oil return apparatus comprises the bottom return tube 2 of base oil sump tank 1, gear-box bottom.Have spill port 3 on base oil sump tank 1 top, be used for inserting the bottom return tube 2 of gear-box bottom; Described base oil sump tank 1 inside is provided with oil return cavity 4, and cavity one side has side return tube 5, and the upper surface of side return tube 5 is lower than the gear-box bottom, and D1 as shown in Figure 1 is abundant to guarantee oil return.The bottom return tube 2 of employing gear-box bottom inserts the mode of the spill port 3 on base oil sump tanks 1 top, is convenient to the installation of gear-box.
Lubricant oil is fully discharged from the bottom return tube 2 of gear-box bottom, the flow through oil return cavity 4 of base, residual lubricant oil is concentrated in this oil return cavity 4, thereby form isolation with the gear-box cavity, comprise the isolation that heat and wearing and tearing iron are cut, thereby can reduce the influence to parts such as gear-box cavity internal gear and bearings, in addition, because the external surface area of base oil sump tank 1 is big, also can further increase heat diffusion area and strengthen base rigidity by gusset is set, the heat that lubricant oil is taken away also can be distributed fast by base oil sump tank 1, plays the effect of quick heat radiating.
The base oil sump tank has two effects, is used for as middle oil sump tank on the one hand, and play fully oil return fast, isolation oil return heat and wearing and tearing iron and cut, and the effect of quick heat radiating, particularly high-speed gear box is particularly important to gear-box for these; On the other hand, itself also is used for the mounting base as gear-box.
In addition, oil sump tank in the middle of base is set to, the gear in the gear-box can be positioned near bottom half as far as possible so, but D2 value as shown in Figure 1 is littler, play the effect that reduces the gear housing center of gravity, this also to gear-box particularly high-speed gear box reduce vibration and play positive role.
Claims (2)
1. milling train gear-box oil return apparatus, it is characterized in that: described device comprises the base oil sump tank that is arranged at the milling train lower gearbox portion
