Description
Technical field
The present invention relates to a kind of for the direct-cooled type bearing support of oil cooling with interior heating hollow shaft equipment technical field equipment.
Background technology
For with interior heating hollow shaft equipment, due to being situated between by high-temperature heating inside hollow shaft in process of production
Matter so that when bearing is mounted on an axle, bearing inner race are heated because being heated axle, with the bearing outer ring hot temperature difference of generation and
Cause Internal and external cycle to expand inconsistent, bearing friction power can be caused to increase even stuck, bearing life is greatly shortened and scrap
Existing cooling type bearing support is that bearing is directly installed on axle, and confined space is formed with pedestal, and to the confined air
Interior injection cooling oil, and coolant is only passed through in bearing seat, after cooling bearing pedestal, then cooling connects with bearing indirectly
The indirect type of cooling of tactile cooling oil, cooling effect is not good, is used reluctantly for low-temperature heat axle, but in the condition of high temperature
When, cooling effect is undesirable, and bearing service life is short.
The content of the invention
Shortcoming it is an object of the invention to overcome prior art, there is provided a kind of good cooling results for interior heating
The direct-cooled type bearing support of oil cooling of hollow shaft equipment, prevents bearing stuck.
The purpose of the present invention is achieved through the following technical solutions：It is a kind of for it is interior heating hollow shaft equipment oil cooling
Direct-cooled type bearing support, including pedestal, axle sleeve and bearing, axle sleeve are sleeved in hollow shaft, and the inner ring of bearing is arranged on axle sleeve middle part,
The outer ring of bearing is equipped with drive end bearing bracket in pedestal in the front side of pedestal, equipped with preceding between the center of drive end bearing bracket and axle sleeve
Seal, locking is provided with preceding sealing gland on drive end bearing bracket, and front seal is pressed in drive end bearing bracket, is filled in the rear side of pedestal
There is rear end cap, rear seal be housed between the center of rear end cap and axle sleeve, locking is provided with rear sealing gland on rear end cap,
And rear seal is pressed in rear end cap, pedestal, axle sleeve, drive end bearing bracket, front seal, rear end cap and rear seal are collectively forming
Airtight cavity, is connected to the coolant inlet joint that is connected with airtight cavity and cooling liquid outlet connects in the both sides of pedestal
Head.
Further, the coolant inlet joint and cooling liquid outlet joint stagger setting.
Further, the coolant inlet joint is arranged at the top rear of pedestal, and the cooling liquid outlet joint sets
It is placed in the lower front of pedestal.
Further, front seal and rear seal are oil sealing.
Further, the axle sleeve includes bearing base, annular groove and cooling bath, and bearing base is respectively provided on two sides with ring
Groove, annular groove is radially extended to bearing base, and multiple cooling baths are provided with vertically in bearing base, and cooling bath is connected with annular groove.
Further, the cooling bath is groove, and the two ends of cooling bath are clogged by sealing plug.
Further, be additionally provided with bearing baffle ring and circlip groove on the bearing base between described two annular grooves, bearing it is interior
Circle side is pressed on the side wall of bearing baffle ring, and opposite side realizes axially position by the end ring in circlip groove.
The present invention has advantages below：
1st, when cooling type bearing support of the invention fixes shaft end, coolant enters in airtight cavity from pedestal, and flows successively
Enter in annular groove and cooling groove, directly axle sleeve cooled down, the Internal and external cycle of bearing heat up will not too high and temperature it is consistent, really
Protecting bearing will not be stuck because inside and outside coil temperature rise is uneven, and on the other hand, axle is not cooled down directly by coolant, can prevented in axle
High-temp liquid is lowered the temperature.
2nd, the invention increased a hollow shaft sleeve between bearing and hollow shaft, by bearing and hollow shaft
Isolated, the annular groove of radial direction and the cooling bath of axial direction are set on axle sleeve, effectively axle sleeve can be cooled down.
3rd, coolant inlet joint and cooling liquid outlet joint stagger setting, can extend stream of the coolant in airtight cavity
Dynamic distance so that each position in airtight cavity is cooled, prevents the even phenomenon of inhomogeneous cooling from occurring.
