Abstract
The utility model discloses a reciprocating sliding sleeve bearing. The sliding sleeve bearing comprises a lower bearing pedestal (1) and an upper bearing pedestal (3) which match with each other in the vertical direction, wherein sliding sleeve bearing bodies are mounted in the lower bearing pedestal (1) and the upper bearing pedestal (3); the sliding sleeve bearing bodies are formed by butt-joint of an upper sliding sleeve bearing body (6) and a lower sliding sleeve bearing body (8) which are symmetric to each other; and the upper sliding sleeve bearing body (6) and the lower sliding sleeve bearing body (8) are made from a material filled with tetra-fluorine. After the reciprocating sliding sleeve bearing disclosed by the utility model is used, the wear and damage of the sliding sleeve bearing bodies and high pressure spraying pipes can be largely reduced, the operation rate of the equipment is increased, the replacing time of spare parts is reduced, the fault in the operation process of the equipment is prevented and the service life of the equipment is prolonged.
Description
Technical field
The utility model relates to a kind of reciprocal sliding sleeve bearing of new structure, belongs to the sliding bearing mechanical equipment technical field.
Background technique
The high-pressure spraying wash tub pipe of pulp machine polyester webs, woollen blanket needs to-and-fro motion, and existing sliding sleeve bearing lubrication poor performance wears no resistance, and water inlet causes lubrication failure easily, sliding sleeve bearing and spray tubular axis easy abrasion.The sliding sleeve bearing wear causes that developing result is poor after damaging, and influences quality of product; And the seat that runs out bearing, damage drive unit, cause shutdown.Causing the spraying tube perforation to damage after the wearing and tearing of high-pressure spraying tubular axis scraps.
Summary of the invention
The technical problem that the utility model will solve is: the reciprocal sliding sleeve bearing that a kind of selflubricating ability is strong, wear-resisting property good, the maintenance grease does not run off, lubricated face is not intake is provided, can overcomes the deficiency of existing technology.
The technological scheme of the utility model is: it comprises step and the upper bearing bracket that cooperates up and down, and the sliding sleeve bearing support is housed in step and the upper bearing bracket, and the sliding sleeve bearing support is made up of the upper sliding sleeve bearing support and the butt joint of low sleeve bearing support of symmetry; Upper sliding sleeve bearing support and low sleeve bearing support are processed by filling PTFE.
On the surface of contact that reciprocatingly slides of sliding sleeve bearing support, offer the oil storage tank that spiral intersects.
On step and upper bearing bracket, be respectively equipped with step oil nozzle and upper bearing bracket oil nozzle, be provided with annular oil groove at the outer surface of upper sliding sleeve bearing support and low sleeve bearing support, step oil nozzle and upper bearing bracket oil nozzle and annular oil groove link.
Offer logical oily aperture on upper sliding sleeve bearing support and the low sleeve bearing support, an end of logical oily aperture is positioned at annular oil groove, and the other end is positioned at the infall of oil storage tank.
Upper sliding sleeve bearing support and low sleeve bearing support are equivalent structure.
On the internal surface of upper sliding sleeve bearing support and low sleeve bearing support, be provided with closure gasket groove, on closure gasket groove, be connected with seal ring.
Compare with existing technology, the utility model has strengthened the wear resistance and the self lubricity of bearing support, the operation period that can improve equipment significantly through changing the material of sliding sleeve bearing support.Upper sliding sleeve bearing support and low sleeve bearing support are designed to horizonally split peering structure up and down, can after the wearing and tearing of lower bearing body, the metal (upper body be exchanged, reduce the maintenance cost of equipment.Through the oil storage tank that spiral intersects is set on reciprocatingly sliding face at the sliding sleeve bearing support, grease can be stored in sliding friction surface like this, reduces friction factor greatly, further increases service life of equipment.Offer logical oily aperture in the oil storage tank and can just lubricating grease be added to sliding friction surface and the spherical surface of rotating through the fuel filler neck from bearing support.Take away when the O V-shaped ring can prevent lubricating grease by the spraying tube to-and-fro motion through being provided with, and can prevent the spraying water engaging friction face of outside at the reciprocating sliding friction face.It is to adapt to the bigger bending deflection that sprays tubular axis that outer surface is designed to spherical.Can greatly reduce the wear damage of sliding sleeve bearing support and high-pressure spraying pipe behind use the utility model, improve the running rate of equipment, reduce the replacing time of spare part, prevent the phenomenon of the failure in the equipment running process simultaneously, increase the working life of equipment.
