Abstract
The invention relates to a split bearing bush seat type sliding bearing tank, which comprises a tank body connected with a casing, a sliding bearing component and a rolling bearing component which are arranged in the tank body and used for supporting a shaft,; the sliding bearing component comprises a bearing bush, an oil ring and a bearing bush installation seat; the rolling bearing is a single four-point contact ball bearing; and a gravity support surface between the tank body and the casing is positioned at the lower part of the sliding bearing component. According to the invention, the technical problems of large volume, large weight and large bending moment of the current sliding bearing tank can be solved, the weight of the bearing tank can be reduced, the capacity of the lubricating oil can be raised, and the installation of the sliding bearing tank is more stable and reliable.
Description
Technical field
The present invention relates to a kind of sliding bearing housing.
Background technique
The bearing housing of existing pump, motor, gearbox need adopt sliding bearing housing sometimes, and the bearing shell fitting seat in the sliding bearing housing is one, and integral body is processed into sphere so that bearing shell to be installed, and this structure has structure and processes simple advantage.Shortcoming is that box weight is big, and the oil sump actual volume is less.
In addition, the general double-row angular contact bal bearing that adopts bears axial force in the sliding bearing housing.But, the big and lubricated cooling inconvenience of double-row angular contact bal bearing heating, and architecture quality is big, complex structure, working service inconvenience.
Also have, rotate in order to prevent the axial force bearing outer ring, sliding bearing housing generally increases overcoat outside the axial force bearing, prevents that through the key that puts the axial force bearing outer ring from rotating outward.
Summary of the invention
The object of the invention provides a kind of split bush seat formula sliding bearing housing, its solved existing sliding bearing housing volume and weight big, bear the big technical problem of moment of flexure.
Technical solution of the present invention is:
A kind of split bush seat formula sliding bearing housing comprises the casing 12 that is connected with housing 7, is arranged on slide bearing assembly that is used for back shaft 8 and rolling bearing assembly in the casing 12; Said slide bearing assembly comprises bearing shell 9, oil ring 11 and bearing shell fitting seat. its special way is:
Said rolling bearing assembly is single four-point contact ball 2;
The gravity supporting surface 1 that said casing 12 and housing are 7 is positioned at the below of slide bearing assembly;
Said bearing shell fitting seat comprises the left bearing shell fitting seat 42 and right bearing shell fitting seat 41 that is symmetricly set on the bearing shell outside; Said oil ring 11 is arranged between left bearing shell fitting seat 42 and the right bearing shell fitting seat 41; Be respectively arranged with the oilhole 10 that is communicated with oil ring and casing on said left bearing shell fitting seat 42 and the right bearing shell fitting seat 41.
Fix through axle sleeve 15 and key between the bearing inner race 14 of above-mentioned single four-point contact ball 2 and the axle 8; Said rear end cover 5 extends in the casing 12 and withstands the bearing outer ring 13 of single four-point contact ball 2; The bearing outer ring 13 of said single four-point contact ball 2 is provided with breach 6; The end face of said rear end cover 5 is provided with pin 3, and said pin 3 inserts in the breach 6 of bearing outer ring 13.
Advantage of the present invention:
1, the present invention is arranged on the link position of sliding bearing box body and housing near near the bearing shell center.Bearing shell bears the radial force that produces in gravity and the operation process of whole axle system, and link position is arranged near the moment of flexure that can reduce gravity the bearing shell center greatly, reduces the load that construction bolt bore, and makes the installation of sliding bearing housing stable more and reliable.
2, bearing shell fitting seat of the present invention is divided into two, and the centre is empty so that oil ring is installed, and sphere is processed in the mounting point of two place's bearing shell fitting seats bearing shell is installed, and such structure greatly reduces the weight of bearing housing, has improved the capacity of lubricant oil.
3, the present invention's bearing structure of bearing axle-system axial power is improved to the axial force that single four-point contact ball bears both direction; Can simplified structure, improve working service property, reduce the heating value of bearing; Make the lubricated and cooling of bearing simpler, make stable and reliable structure.
4, the present invention is through axle sleeve and key stationary axle and bearing inner race; The breach that inserts on the bearing outer ring through the pin on the rear end cover prevents that bearing outer ring from rotating, and has abandoned the design of overcoat, simplifies the structure; Improve the lubricated and cooling effectiveness of this bearing, improve reliability of structure and maintainability.
