Abstract

The utility model provides a casting split type water-cooling rolling bearing seat. The casting split type water-cooling rolling bearing seat comprises a bearing seat, a bearing seat cover plate, a bearing cover, a bearing cover cover plate, a sealing ring, a blocking ring, a penetrable cover and an impenetrable cover and is characterized in that the bearing cover and the bearing cover cover plate are welded into a sealed box body with an upper limber hole; the bearing seat and the bearing seat cover plate are welded into a sealed box body with a lower limber hole; and the bearing cover and the bearing seat are communicated through a water hole. A joint face of the bearing cover and the bearing seat is provided with the sealing ring, the bearing seat is provided with a water inlet, and the bearing cover cover plate is provided with a water outlet. Abearing and a bearing sleeve are arranged on a shaft, and the bearing cover and the bearing seat are mounted into a whole through bolts, nuts and a gasket. The casting split type water-cooling rolling bearing seat has the advantages of being simple and compact in structure, convenient to demount and maintain and low in construction cost. Spill points of water are few, water flow is smooth in the cavity, service life of the bearing is long, and accident rate is low.

Description

A kind of casting Split type water-cooling rolling bearing pedestal

Technical field:

The utility model relates to hot rolling supplementary equipment technical field, particularly relates to a kind of casting Split type water-cooling rolling bearing pedestal that uses under high temperature, the rugged environment.

Background technique:

At present, in hot rolling supplementary equipment technical field, plain bearing housing generally all adopts the entity shell type structure, does not have self-cooling function, at high temperature or have under the working environment of infrared source, behind the heat absorption of bearing support body and the bearing movable frictional heat, temperature is higher in the bearing support, and lubricated environment is destroyed, can have a strong impact on the working life of bearing, even finally cause bearing support to lose efficacy the driving mechanism cisco unity malfunction.In the prior art, usually can adopt with spraying heat radiation, neither attractive in appearancely again water resources caused severe contamination and waste.

The model utility content:

The purpose of this utility model is exactly to overcome the defective that above-mentioned prior art exists, provide a kind of under high temperature or rugged environment the water-cooled rolling bearing support of the critical component long service life such as reliable performance, safety, environmental protection, bearing.

The utility model is achieved through the following technical solutions: a kind of casting Split type water-cooling rolling bearing pedestal is provided, comprise that interconnective bearing base, bearing base cover plate, bearing cap, bearing cap cover plate, seal ring, back-up ring, transparent cover, stifle form, it is characterized in that: bearing cap and bearing cap bridge welding are connected into the airtight casing with upper water port; Bearing base and bearing base bridge welding are connected into the airtight casing in water port under the band; Bearing cap is communicated with by water passage hole with bearing base; Bearing cap and bearing base mating face are provided with seal ring, have on the bearing base on water inlet, the bearing cap cover plate and have osculum; Bearing and axle sleeve are contained on the axle; Bearing cap and bearing base are mounted to an integral body by bolt, nuts and washers; The end bearing block that moves about utilizes the shaft shoulder, axle end baffle plate and screw that bearing inner race is fixed, and moves about in the outer ring, is provided with oilhole at the fixing distolateral circular stifle middle part of axle; The fixed end bearing support contacts with transparent cover by 2 back-up rings the outer ring of bearing is fixed, and by the shaft shoulder and axle sleeve bearing inner race is fixed; Transparent cover is provided with oil inlet hole; Bearing cap and bearing base are designed with the mazy type lubrication sealing structure.

The beneficial effects of the utility model are: only open a water port at upper ball cover and lower bearing base surface of contact, and the design sealing configuration, effectively prevented overflowing of water; The die cavity that is filled water around the bearing surrounds, current are unimpeded without the dead point in the whole die cavity, and heat and the effectively thermal etching of isolated environment of flowing and effectively producing with bearing running of water always work under the lower temperature bearing, thereby guarantee the long service life of bearing, the critical component accident rate is low; It is simple in structure, compact, demolition and maintenance convenient, cost is low.
