Abstract
The utility model discloses a split type frame seal, aiming at solving the problems of time wasting and labor wasting since the part which prevents the frame seal from passing though a shaft end has to be disassembled when changing the frame seal due to an integrated structure. The split type frame seal comprises an annular seal body which is internally provided with a strengthening frame and a reinforcing spring, wherein the annular seal body is formed by the split joint of two semicircular seal bodies which are internally provided with strengthening frames, the reinforcing spring is an opened structure, one end of the reinforcing spring is provided with outer screw thread, and the other end of the reinforcing spring is provided with inner screw thread. The split type frame seal can fast change the frame seal without disassembling the parts such as a coupler and the like when changing the frame seal during overhauling, thereby saving the overhauling time and reducing the labor intensity.
Description
Technical field
The utility model relates to reinforced seal, is specifically related to a kind of split type reinforced seal.
Background technique
Existing reinforced seal is an outside framework oil seal, and being used for needs the parts that lubricate and the parts of exerting oneself to isolate transmission part, is unlikely to allow oil seepage.Existing reinforced seal is an integral type, comprises the annular seal body and the reinforcement spring that are provided with web frame in it, and seal is divided into bottom, waist, cutting edge and sealing lip etc. again according to different parts, and the reinforcement spring is placed in the waist of seal.Web frame plays the effect of reinforcement, and makes the sealing physical efficiency keep shape and tension force.The reinforcement spring is compensation sealing self-tightening power at any time.Under free state, the internal diameter of reinforced seal is littler than the diameter of axle, promptly has certain " magnitude of interference ", when sealing is packed into after sealing seat and axle go up, the contractile force of the pressure of the cutting edge of seal and reinforcement spring produces certain radially tight power to axle, and the reinforcement spring is compensation sealing self-tightening power at any time.Owing between sealing and axle, exist the oil film of sealing cutting edge control, this oil film has the fluid lubrication characteristic, and under the effect of surface tension of liquid, the rigidity of oil film makes oil film and air contact jaw form a new lunar surface just, prevent the leakage of working medium, thereby realized the sealing of running shaft.
In use, seal directly contacts with the rotation axial workpiece, and is improper in the reinforced seal model that runs into selection, when reason such as not in place is installed, can cause reinforced seal that the contact surface abrasion of rotating axial workpiece is caused leakage of oil.Because the seal and the reinforcement spring of existing reinforced seal are the ring structurees of one, must its part by axle head will be limited during replacing, as dismountings such as coupling, can install, in order to change a reinforced seal, maintenance process usually needs speed reducer is disintegrated, and needs very big labor intensity, with a large amount of repair times, waste time and energy.
Summary of the invention
The utility model must be removed limiting its part by axle head during replacing in order to solve existing reinforced seal owing to be integral type, can install, and has the problem that wastes time and energy, and a kind of split type reinforced seal is provided.
The utility model is achieved through the following technical solutions:
Split type reinforced seal, comprise the annular seal body and the reinforcement spring that are provided with web frame in it, wherein the annular seal body is combined into by two semicircular seals that are provided with web frame in it, and the reinforcement spring is an open architecture, one end is provided with outside thread, and an end is provided with internal thread.During use, two semicircular seals that are provided with web frame in it are docked on the axle, the reinforced seal integral body of synthesis of cyclic, the reinforcement spring is in place, internal thread and outside thread by two ends connect into ring, it is the same with existing reinforced seal structure that the back is installed, and produces sealing and frizing effect.
The described semicircular web frame that is provided with seal one end of web frame in it protrudes from the end face of seal and forms positive groove, recessed time of the web frame of the other end is in the end face of seal and form cloudy groove, the negative and positive groove plays the effect of location, positive groove and cloudy groove with two seals during installation are docked on the axle, the reinforced seal integral body of synthesis of cyclic.
When the utility model has realized that maintenance process is changed reinforced seal, do not need to remove the effect that component such as coupling can be changed reinforced seal fast, saved the repair time, reduced labor intensity.
