Description
Technical field
The present invention relates in a kind of machinery running shaft with bearing housing or gear box lubricating oil (fat) seal arrangement, specifically a kind of assembly type Split type framework oil seal.
Background technique
On market, be generally used for bearing housing and the main employing of gear-box sealing felt rug sealing and labyrinth seal that axle head is difficult to disassemble, or the seal form of felt rug sealing and labyrinth seal use.These two kinds of seal form are in equipment confession, the normal situation of oil return, and sealing effect is relatively good, and working life is longer.But, when equipment supplies, oil return system breaks down or artificially fuel feeding is excessive, surely there will be a large amount of leakages, and when start and shutdown, no matter whether fuel feeding is normal, all can occur leaking.
For above-mentioned seal leakage situation, lack in the market solution and product supply targetedly.While seal failure occurring, mostly adopt the devices such as oil trap is set below seal leakage point to collect the fluid leaked, also have and directly below leakage point, stack the fluid that sand or slag absorb leakage.These methods can only be controlled the unlikely large size diffusion of the fluid leaked, and can't avoid oil liquid leakage, waste and environmental pollution.Oil liquid leakage directly threatens equipment safety operation, thereby impact is produced.
Summary of the invention
The object of the invention is to solve the sealing difficult problem in existing labyrinth seal and felt rug seal failure situation, provide a kind of and form the split type one by sealing lip, bizet, spring groove, skeleton, shoulder, boss, groove, latch, jack, back, waist, dust excluder lips, and mounting spring applies pretightening force to sealing lip in spring groove, easy for installation, seal reliable assembly type Split type framework oil seal.
Solve the problems of the technologies described above by the following technical solutions: a kind of assembly type Split type framework oil seal comprises the sealing lip, bizet, spring groove, skeleton, shoulder, several boss, groove, latch, jack, back, waist and the dust excluder lips that form the split type integrative-structure; Described sealing lip is positioned at the described spring groove in the described bizet outside and is positioned at described bizet inboard, and described dust excluder lips is positioned at the described waist outside; Described boss is positioned at described shoulder excircle central authorities, is provided with described groove between every two boss, and described shoulder and boss, groove, back, dust excluder lips, waist, bizet, sealing lip, spring groove are connected to one.
Described skeleton is arranged in described shoulder, and the two ends, subdivision place of described shoulder are respectively equipped with latch and jack; Described skeleton is the loop configuration with the subdivision mouth, and latch and skeleton are the split type integrative-structure.
Described latch and described jack, for connecting matching mechanism, lay respectively at the two ends, subdivision place of assembly type Split type framework oil seal, and two ends, subdivision place connect as one by latch and jack respectively, and latch and skeleton are the split type integrative-structure.
Described bizet inboard is provided with described spring groove, described spring is installed in described spring groove, for to sealing lip, applying pretightening force.
Compared with prior art, the invention has the beneficial effects as follows:
While (1) installing, only the assembly type Split type framework oil seal need be installed in split type equipment end cap and get final product, without the original-pack sealed member of device for disassembling, install extremely convenient and swift.
(2) adopt latch and jack to connect matching mechanism the subdivision place is connected, be aided with simultaneously gluingly, can realize the sealability identical with unitized seal and effect.
(3) frame design in shoulder improves shoulder intensity of the present invention greatly, thereby guarantees closely cooperating between its shoulder and split type equipment end cap endoporus.
(4) skeleton in shoulder is the spring steel material, and while guaranteeing that it is installed, breaking into two with one's hands from subdivision can also free fourth contact after being enclosed within on running shaft and indeformable.
(5) be positioned at the boss design of shoulder excircle central authorities, guaranteed concentricity and the perpendicularity of a whole set of assembly type Split type framework oil seal and running shaft.
(6) simple in structure, to process easyly, cost is lower, and strong adaptability is conveniently changed online, can effectively increase work efficiency, saves time and reduce cost of equipment maintenance.
