Abstract

The invention discloses a self-lubricating bearing for a hydraulic steel gate, and the self-lubricating bearing comprises a tubular base body which is arranged on the neck of a shaft in a cup joint way, wherein a plurality of pre-openings are distributed on the tubular base body, each pre-opening is sequentially provided with a solid lubricant and a thrust spring from inside to outside, the solid lubricant is in clearance fit with the pre-openings, the tubular base body is externally provided with a bearing bush type fixed shell fixed on the tubular base body by sunk screws, and the inner wall of the bearing bush type fixed shell leans against the outer ends of the thrust springs. The lubricating mode provided by the self-lubricating bearing is active lubricating, i.e., the solid lubricant is in clearance fit with the pre-openings of the tubular base body, the pre-openings are gradually exposed under the effect of the thrust springs, and the pre-openings can be well contacted with the neck of the shaft, so that the lubricant can be continuously provided due to the 'active wear' of the solid lubricant, therefore, the wear of the base body can be reduced, and the service life of the bearing can be prolonged; and when lubricating blocks taken as the solid lubricant are exhausted, the self-lubricating bearing can be continuously used only by changing the lubricating blocks, so that the maintenance cost can be reduced.

Description

A kind of self oiling bearing that is used for hydraulic steel gate
Technical field
The present invention relates to a kind of bearing structure, specifically, relate to a kind of and lubricated relevant bearing structure.
Background technique
Construction along with some high dams of China; The water pressure that main gate and bulkhead gate bore of its bottom outlet is increasing; And as the structure that these water pressures is passed to dam body; The walking support of plane steel gate and the swirl gears such as rotating hinge of steel arch-gate operate mainly under the condition of low-speed heave-load, and this operating mode form has determined the sliding bearing of these revolving mebers can not form the oil film of complete densification.If use traditional grease lubrication, with sliding bearing is operated under the situation of boundary friction, this will cause between axle journal and the bearing and produce rapid wearing, or even stuck phenomenon.Because the requirement of the not competent this special operation condition of common liq lubricating bearings, so inlaid type self oiling bearing and the integral sintered type self oiling bearing of powder metallurgy arise at the historic moment.
The structural feature and the working principle of traditional inlaid type self oiling bearing are: as depicted in figs. 1 and 2; On metallic matrix, design, process the hole of certain area ratio in advance; And in these preset holes, be inlaid into solid lubricant; Through binder-treatment, make these two kinds of structures of metallic matrix and solid lubricant form an integral body, and be processed into bearing, bearing shell or liner plate.As shown in Figure 3, all inlaid holes are crisscross arranged along gyratory directions, axially or radially between each inlaid hole certain degree of overlapping α should arranged, and cover whole glide direction to guarantee solid lubricant, form complete solid lubricant film.Self oiling bearing because heat effect and axle journal and the rubbing action of self make solid lubricant constantly ooze out transfer, along with the continuous wearing and tearing of metallic matrix, makes solid lubricant expose out gradually when motion simultaneously, thereby plays lubricated and antifriction function.
The structural feature and the working principle of the integral sintered type self oiling bearing of traditional powder metallurgy are: like Fig. 4 and shown in Figure 5; The integral sintered self-lubricating solid bearing of powder metallurgy is that solid lubricant powder and metallic matrix raw material are mixed each other; And through zine stearate as Bond with its press forming, sintering; Formation has the selflubricating matrix composite in a lot of spaces, is processed into bearing, bearing shell or liner plate.Because material itself has added certain solid lubricant and bearing will produce heat effect at work; Make the solid lubricant of self will form the comparatively stable lubricating layer of one deck in its surface; And rely on the wearing and tearing of self constantly to replenish solid lubricant; Repair the lubricating film of being torn, thereby reach lubricated and antifriction function.
It is thus clear that above-mentioned two kinds of traditional self oiling bearings all are to adopt " self-loss " to come constantly to provide oiling agent, this lubricating system to cause axle journal and bearing wear serious.
Summary of the invention
The present invention will solve is to be embedded in the technical problem that solid lubricant on the matrix can not " initiatively wearing and tearing " comes constantly to provide oiling agent; A kind of self oiling bearing that is used for hydraulic steel gate is provided; Can make the body material of self oiling bearing self not wear and tear or wear and tear seldom; But let solid lubricant self " initiatively wearing and tearing " reach oiling agent is provided constantly, satisfies lubricated needs.
In order to solve the problems of the technologies described above, the present invention is achieved through following technological scheme:
A kind of self oiling bearing that is used for hydraulic steel gate; Comprise that being used for socket is installed in the tubular matrix on the axle journal; Be distributed with a plurality of pre-drilled cavities on the said tubular matrix; Solid lubricant and thrust spring are installed in the said pre-drilled cavity from inside to outside successively; Said solid lubricant and said pre-drilled cavity Spielpassung, the outside socket of said tubular matrix is equipped with through sunk screw and is fixed on the bearing shell formula set casing on the said tubular matrix, and the inwall of said bearing shell formula set casing is resisted against said thrust spring outer end.
Said bearing shell formula set casing is put together by two same bearing shell formula set casing assemblies, and two said bearing shell formula set casing assemblies line of position each other is a stepped shaft.
Said tubular matrix two ends are respectively arranged with seal ring, and said seal ring outer installment has through the fixing end cap of the seal ring of screw on said tubular matrix.
The clearance distance of said solid lubricant and said pre-drilled cavity is 0.00005m~0.00015m.
The internal diameter of said tubular matrix is d 2, unit is m; d 2=d 1+ (0.00005m~0.00015m); In the formula: d 1Be the diameter of said axle journal, unit is m.
The wall thickness of said tubular matrix is l 3, unit is m; l 3>=l 1+ l 2In the formula: l 1Be the minimum length of said thrust spring after being compressed, unit is m; l 2Be the height of said solid lubricant, unit is m.
The quantity of said pre-drilled cavity In the formula: S is the area of said pre-drilled cavity, and unit is m 2d 3Be the diameter of said pre-drilled cavity, unit is m.
The invention has the beneficial effects as follows:
The lubricating system that self oiling bearing provided that is used for hydraulic steel gate of the present invention is initiatively lubricated; To be solid lubricant unlike traditional self oiling bearing such and matrix is fixed or mix; But with the pre-drilled cavity Spielpassung of tubular matrix, solid lubricant can move freely in pre-drilled cavity.Solid lubricant just can expose pre-drilled cavity gradually under the effect of thrust spring like this; And contact well with axle journal; " initiatively wearing and tearing " come to provide continuously oiling agent so that solid lubricant self, thereby reduce the matrix wearing and tearing, improve bearing working life; When the lubricated piece as solid lubricant exhausts, only need to change lubricated piece and just can continue to use in addition, reduced maintenance cost.
