Abstract

The bearing box for blower uses automatic circulation to cooling lubricant for lubrication and heat dissipation and features that its rollers can not be jammed and the maximum diameter of main shaft is not limited by the size of bearing as the oil basin of bearing box is made into two with different levels, thus increasing the critical rotation speed of rotor and solving the problem of oil leakage.

Description

Position differential type self-circulation water-cooling bearing box
The invention belongs to the bearing housing in the blower fan industry, bearing housing in the blower fan industry adopts the mode of bearing outer ring cooling to dispel the heat more at present, but this mode is different to the heat dissipating capacity of the inner ring of bearing outer ring and high speed rotating and ball, to cause the outer ring is the trend of contraction, inner ring and ball are the trend of heat expansion, when expanding to the rotation of no gap, then bearing must decrease ring.Especially concerning high-precision bearing, this kind phenomenon is damaged even more serious.And for make that ball is immersed in the oil, the oil sump level height under bearing ball 1/2 ball diameter height place, the maximum diameter 0<dm<dm of main shaft is the span size at two symmetrical ball centers like this).As 0>dm, the diameter of axle will be below the oil level line.Therefore the size of bearing has limited the diameter of axle of main shaft, thereby has limited the critical speed of rotation of rotor.Application number is: 91210220.9 utility model patent discloses a kind of to the water-cooled mode of blower fan exocoel.This mode still can't resolve the different problem of heat dissipating capacity of the inner ring and the ball of bearing outer ring and high speed rotating.The present invention designs at above problem.
Purpose of the present invention designs a kind of bearing outside and essentially identical fan bearing case of ball degree of heat radiation of making exactly, makes that like this bearing internal clearance is constant, has overcome stuck phenomenon in the past.
Design proposal of the present invention is: the bearing housing oil sump is made two oil sumps up and down, and below the ball, following oil sump is below bearing spindle under bearing for last oil sump.Water-cooling tube is placed on down in the oil sump lubricant oil is cooled off, to descend the cold oil in the oil sump to get rid of when being fixed with disc on the main shaft to oil trap with main axis rotation, oil trap is collected cold oil and is splashed into oil hole, and the inflow of process oil-feed tank is gone up in the oil sump, the oil-return groove outlet is placed on ball 1/2 diameter height place under the pool side bearing that oils, when the oil in the last oil sump surpassed down ball 1/2 diameter, oil flowed into oil sump bottom down automatically from oil-return groove through return tube.Oil hole, oil-feed tank, oil-return groove all are to process on the lower base of bearing housing.
The bearing housing oil sump is made two oil sumps up and down, and following oil sump oil level is lower, and the maximum diameter of axle of main shaft is not subjected to the restriction of bearing size like this, can improve the critical speed of rotation of rotor.Simultaneously bearing outer ring is not cooled off, and water-cooling tube is placed on down cutting oil in the oil sump, to descend the cold oil in the oil sump to get rid of when being fixed on disc on the main shaft to oil trap with main axis rotation, oil trap passes through oil hole, oil-feed tank with cold oil, oil sump in the injection, Leng Que lubricant oil is that lubricate plays cooling action again to bearing like this, because bearing outside is also the same substantially with the basic identical heat expansion degree of ball degree of heat radiation, so the gap is constant substantially.Overcome stuck phenomenon in the past.When the oil of last oil sump surpasses down ball 1/2 diameter, then oil will flow into down from oil-return groove, return tube that oil sump cools off so continuous circulation, cold and hot exchange automatically.
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail:
In the accompanying drawing: (1) bearing housing; (2) return tube; (3) water-cooling tube; (4) oil sump under; (5) bearing; (6) disc; (7) main shaft; (8) oil trap; (9) oil hole; (10) oil-feed tank; (11) oil-return groove; (12) go up oil sump.
When main shaft (7) rotates, the disc (6) that is fixed on the main shaft (7) will rotate with main shaft.Disc (6) will descend the lubricant oil of cooling in the oil sump (4) to take up, under action of centrifugal force, oil is got rid of to oil trap (8), by oil trap (8) the oil collection is splashed in the oil hole (9), oil flows to 8 points by the oil-feed tank of processing (10) on bearing housing (1) inwall.In 8 inflows, in the oil sump (12), provide the lubricant oil of cooling to bearing.When oil level is higher than ball 1/2 diameter half under the bearing, then oil will be automatically from oil-return groove (11) process O point, deep fat is flowed into the E point, again through return tube (2), crossing the F point gets back to down in the oil sump (4) to the G point, the deep fat of getting back to down in the oil sump (4) is taken away heat by water-cooling tube (3), by such cyclic process, to reach the purpose of lubricated heat radiation.Simultaneously because oil hole (9), oil-feed tank (10) and solid oil groove (11) are all processed on bearing housing (1) lower base, and the maximum oil position of letting out (12) that oils is the O point, so this bearing housing can leakage of oil, have overcome oil leakage phenomenon in the past.

Claims (3)

1, a kind of by bearing housing, the fan bearing case of compositions such as bearing, main shaft, oil sump, water-cooling tube is characterized by:
The bearing housing oil sump is made oil sump (12) and (4) two oil sumps of following oil sump, water-cooling tube (3) is placed on down in the oil sump (4) lubricant oil is cooled off, can will descend the cold oil in the oil sump (4) to get rid of when being fixed with disc (6) on the main shaft (7) to oil trap (8) with main axis rotation, oil trap (8) is collected cold oil and is splashed into oil hole (9) through in the oil sump (12) in oil-feed tank (10) inflow, oil-return groove (11) outlet is placed on ball 1/2 diameter height place under the pool side bearing that oils, when the oil in the last oil sump (12) surpassed down ball 1/2 diameter, oil flowed into oil sump (4) bottom down from oil-return groove (11) through return tube (2) automatically.
2, it is characterized by according to the bearing housing described in the claim 1: go up oil sump (12) below bearing ball and the maximum oil position be ball 1/2 diameter height place under bearing, following oil sump (4) is below main shaft, oil level is height below the ball minimum point under bearing.
3, it is characterized by oil hole (9) according to the bearing housing described in the claim 1, oil-feed tank (10), oil-return groove (11) all is to process on the lower base of bearing housing (1).
