Abstract
The utility model discloses a kind of oil return apparatus for forced lubricating system bearing housing, it is characterized in that, this device comprises a spill port joint, described spill port joint has the cavity volume that holds oil return, is provided with downward-sloping return tube connection mouth in the oil circuit output terminal bottom of spill port joint.The utility model device adopts spill port joint to be connected with spill port, be connected with return line by return tube connection mouth again, thereby increase the oil return area at spill port place, under equal conditions, cooling oil mass can be significantly increased and can oil spilling, oil return effect and lubrication effect can be significantly improved.
Description
Technical field
The utility model relates to a kind of for forced lubricating system bearing housing and oil return apparatus thereof.
Background technique
Adopt the fluid machinery rolling bearing bearing case of pressure lubrication, for ensureing lubrication effect and the safety reliability of rolling bearing, when General Requirements is normally worked, oil return is effective, reliability high (adopt top petrol tank) when non-normal working (as Lubricating-oil Station power-off).The mode that the oil supply of existing bearing housing lubricant oil and oil return generally all adopt pipeline to connect, but in actual use, in the situation that Lubricating-oil Station machine operation rotating speed is constant, due to the factor such as temperature, the viscosity impact of lubricant oil, can cause following two kinds of situations to occur: 1, when oil temperature is high, oil viscosity hour, because pipe resistance diminishes, cause increasing to oil mass, cause oil return not smooth, in bearing housing, oil level raises gradually, when oil leakage phenomenon appears in height to a certain extent.2, when oil temperature is low, oil viscosity is when large, because pipe resistance becomes large, cause to low on fuel, in bearing housing, oil level reduces gradually, when to a certain extent low and cause bearing lubrication poor effect, if lubricant oil does not directly pour the operating mode on bearing, even can cause bearing to burn because of lack of lubrication.
Model utility content
The deficiency existing for fear of prior art, the utility model provides a kind of oil return apparatus for forced lubricating system bearing housing.
The utility model technical solution problem adopts following technological scheme:
A kind of oil return apparatus for forced lubricating system bearing housing, its structural feature is, this device comprises a spill port joint, and described spill port joint has the cavity volume that holds oil return, is provided with downward-sloping return tube connection mouth in the oil circuit output terminal bottom of spill port joint.
The utility model structural feature is also:
Described return tube connection mouth downtilt angles is greater than 15 °.
Described spill port joint and return tube connection mouth are integral type structure.
A kind of comprise bearing housing for forced lubricating system bearing housing, described bearing housing is provided with spill port, and its structural feature is, described spill port place is connected with the oil return apparatus described in claim 1-3 any one.
Described spill port is rectangular, and the bottom interior wall of described spill port joint is lower than the bottom plane of spill port.
Described spill port bottom plane flushes with the minimum guarantee lubricant oil of bearing bit line or is slightly high.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model device adopts spill port joint to be connected with spill port, be connected with return line by return tube connection mouth again, thereby increase the oil return area at spill port place, under equal conditions, cooling oil mass can be significantly increased and can oil spilling, oil return effect and lubrication effect can be significantly improved.
2, the utility model bearing housing return opening bottom line (being bottom plane) is higher than the minimum lubricant oil bit line of bearing, and in the time of dilute oil lubrication station power-off, the trapped fuel in bearing housing also can ensure the lubricated of bearing.
3, oil return apparatus and have the bearing housing of large sump volume combination replacement the combination of top petrol tank and traditional bearing case, saved top petrol tank and associated conduit, valve etc., saved manufacture cost, reduced maintenance cost.
4, because the return opening of bearing support becomes rectangular from circle, strengthened oil return ability, at least 15 ° of return tube pipe maintenances are downward-sloping in addition, even if ensured, increase to oil mass, lubricant oil is oil return in time also, it is stable that oil level can keep all the time, there will not be and leak oil condition because oil level is too high.
Brief description of the drawings
Fig. 1 is the utility model oil return apparatus structural representation.
Fig. 2 is the utility model oil return apparatus side cutaway view.
Fig. 3 is the utility model oil return apparatus and bearing housing assembling schematic diagram.
Fig. 4 is the utility model oil return apparatus and bearing housing assembling stereoscopic-state figure.
Number in the figure: 1 spill port joint, 2 return tube connection mouths, 3 bearing housings, 4 bearings, 5 spill ports, the minimum bit line of 6 lubricant oil, 7 oil sumps, 8 sealing surfaces, 9 are fastenedly connected hole, 10 return opening bottom planes.
By embodiment, technical solutions of the utility model are further explained to explanation below in conjunction with accompanying drawing.
Embodiment
As shown in Figure 1, 2, oil return apparatus, comprises a cuboid spill port joint 1, and spill port joint has the cavity volume that holds buffer memory oil return, is provided with downward-sloping return tube connection mouth 2 in the oil circuit output terminal bottom of spill port joint; Return tube connection mouth downtilt angles a is more than or equal to 15 °, and the bottom plane of return tube connection mouth should be lower than return opening bottom plane.When production, spill port joint and return tube connection mouth are welded into an entirety, sealing surface is set and is fastenedly connected hole at the connecting end surface of spill port joint, are convenient to be connected with bearing housing and seal with fastening piece.
Forced lubricating system bearing housing as shown in Figure 3-4, comprise bearing housing 3, profit is changed bearing 4 and is located in bearing housing 3, and bearing housing 3 is provided with rectangular spill port 5, and spill port bottom plane 10 flushes with the minimum lubricant oil bit line of bearing or slightly high (ensureing that bearing ball 1/3 is immersed in lubricant oil).Spill port 5 places connect oil return apparatus as above; When assembling, the spill port joint bottom plane (being bottom interior wall) of oil return apparatus should be lower than the bottom plane 5cm left and right of spill port.
Claims (4)
