Background technique
Displacement pump line running state is the gap working state, and its bent axle motion is stressed mainly to be radial force, and the situation before the cold rolling unit transformation after the generation of displacement pump fault mainly shows the wear damage of sliding bearing; The transverse breakage of bent axle.Rolling dose of use of technology during the rolling flat cold-rolled sheet of the cold rolling unit of former flat cold-rolled sheet factory be animal oil and fat, after animal oil and fat entered cesspool, its sewage with oil was bigger; Therefore cold-rolling process is transformed, the technology that cold rolling unit is adopted changes emulsified liquid into for rolling dose, and the oiliness of sewage has reduced much like this.But because the change of rolling dose of the technology of rolling flat cold-rolled sheet, make the lubricated conformability of former displacement pump material for sliding bearing (special porous matter) change, make the sliding bearing lubricating decreased performance of displacement pump, form sliding bearing easily with the bonding phenomenon of anti-wear sleeve, thereby the fault that causes the displacement pump crankshaft rotating to stop.
Summary of the invention
The utility model is intended to overcome the defective of existing bearing means, and a kind of displacement pump bent axle tail end bearing means is provided.The utility model has effectively been blocked liquid seepage in bearing support in the pump, has guaranteed the lubricating status of needle bearing, has prolonged the working life of pump crankcase greatly, thereby has avoided causing cold rolling compressor emergency shutdown because of displacement pump quits work.
The utility model is achieved in that a kind of displacement pump bent axle tail end bearing means, comprise the displacement pump body, bent axle, bearing support, bearing cover, the Bearing Installation axle sleeve, be sleeved on the Bearing Installation seat of displacement pump bent axle tail end and the bearing between the bearing support, bearing support is located in the displacement pump body axis hole, this bearing support is to connect the displacement pump body by set screw nut, the terminal bearing installation shaft of described bent axle cover is covered with a bearing setting sleeve that props up bearing, to use check ring, described bearing near the internal circlip of bearing and axle be needle bearing and be set with on the described Bearing Installation axle sleeve.
Described displacement pump bent axle tail end bearing means, with screw a trapezoidal mazy type water holding ring is arranged on the described bearing support interior edge face, this trapezoidal mazy type water holding ring is provided with some dashpots towards the end face of pump inner chamber, and the hole wall of endoporus is provided with the trapezoidal radially convex surface in some roads; Described Bearing Installation axle sleeve is fixed on described bent axle tail end with an assembling-disassembling bolt, and its front end is provided with the groove with trapezoidal mazy type water holding ring internal diameter convex surface coupling; Described needle bearing is sleeved on described installation shaft and puts; Described axle with and internal circlip is arranged on the two ends of needle bearing and respectively near the axial motion with the qualification needle bearing of the inside and outside circle of needle bearing.
Described displacement pump bent axle tail end bearing means also is provided with a pair of backbone sealing ring between described trapezoidal mazy type water holding ring and needle bearing interior edge face, and described backbone sealing ring is back-to-back setting or connects towards bearing.
Described displacement pump bent axle tail end bearing means, described bearing support is provided with the lubricating oil path that leads to needle bearing that has direct-filling type drier oil mouth, and described bearing setting sleeve bottom is provided with fuel outlet and to drain the oil screw sealing.
The utility model needle bearing inner ring is contained on the bearing supporting sleeve of band maze trough of pump crankcase tail end, between needle roller dynamic bearing and swing volume wheel rotor, trapezoidal mazy type water holding ring is set, sealing between needle bearing and mazy type water holding ring is adopted twice reinforced seal (back-to-back form or towards the bearing series connection) is installed, the needle bearing inner ring is located by check ring, processed lubricating oil path on the pump shaft bearing and the needle bearing outer ring has been installed, the needle bearing outer ring is moved axially by check ring and bearing cover (needle bearing setting sleeve) positioning control, and the dismounting of bearing supporting sleeve is carried out by the special-purpose assembling-disassembling bolt on the bent axle tail end.As seen, the utility model has been discarded the sliding bearing of former special porous material, adopts needle bearing, reduces manufacture cost, improves installation precision; Increase the installation of mazy type water holding ring and twice reinforced seal, effectively blocked liquid seepage in bearing support in the pump, guaranteed the lubricating status of needle bearing, prolonged the working life of pump crankcase greatly.
