Description
The utility model relates to the coupling in a kind of common engineering domain engineering parts, particularly relates to a kind of universal coupling with spider that self has accumulator.
In existing universal coupling with spider, China has formulated the universal coupling with spider of three kinds of standard types, be JB3241-91SWP type (segment bounds), JB5513-91SWC type (whole fork head type), JB/T3242-93SWZ type (solid housing formula), the universal coupling with spider that also has some nonstandard products, they are widely used in the transmission of heavy machinery of all kinds of rolling mill, inspection machine and heavy duty, frequent clockwise and anticlockwise.These existing universal coupling with spiders all need refuel before use, beginning a period of time is one class and adds once oil, length also wants to add in two weeks once oil more later on, otherwise the thirsty phenomenon of oil promptly takes place in coupling for want of lubricant oil, and make cross axle and bearing wear, have a strong impact on the working life of coupling.Yet frequent the oiling, then increased the weight of working strength of workers, particularly in steel rolling mill, the operating time continuity is long, and work under bad environment, be full of dust, made that miantainers are not easy to refuel, and often forget oiling, renew thereby when not reaching due service life, scrapped the working life that causes coupling, particularly under hot environment, because lubricant oil volatilization and leakage easily easily then causes its filling cycle shorter.The basic reason that produces the problems referred to above is that its lubricant oil of existing coupling is after tank filler sleeve refuels, and the cross oil circuit in cross axle removes the surface of contact of lubricating bearings and cross axle again to the bearing diffusion, then at the tank filler sleeve plug screw of screwing on.This structure makes that volume read-out of lubricant oil is few, so its filling cycle is short, comes off easily after its plug screw is vibrated simultaneously and produces oil leakage phenomenon, has then more shortened the cycle of refueling.This shows that above-mentioned existing universal coupling with spider still has many defectives, and the assistant officer waits to be improved.
Because the defective that above-mentioned existing universal coupling with spider exists, the design people is actively studied innovation, through constantly studying, designing based on abundant practical experience and professional knowledge, and after studying sample and improvement repeatedly, create the utility model finally.
Main purpose of the present utility model is, overcome the defective that existing universal coupling with spider exists, and provide a kind of new structure self to have the universal coupling with spider of accumulator, make its volume read-out big, lubricant oil can be used reached six months even the longer time, prolong the cycle of refueling greatly, have the oiling of minimizing number of times, alleviate maintenance labor intensity, improve coupling working life and economical and practical effect.
The purpose of this utility model is realized by following technological scheme.According to a kind of universal coupling with spider that self has accumulator that the utility model proposes, be provided with cross axle and bearing, it is characterized in that it comprises cross axle, bearing, check valve sheet, accumulator and vinyl cover, wherein: this cross axle, be respectively equipped with four bearings, be provided with the cross oil circuit in this bearing, offer accumulator at the central part of this cross axle, this accumulator is connected with above-mentioned cross oil circuit; This bearing, its outer shroud center is provided with tank filler sleeve, and the spiral shell establishing is closed and is provided with a plug screw in this tank filler sleeve, and the bottom interior wall of bearing is provided with the groove of a logical oil; This check valve sheet is arranged in the inner groovy of the cross oil circuit port part in the cross axle, is provided with a spring in the groove of the cross oil circuit port part of cross axle, and the central part internal surface that this spring holds check valve sheet and outer race fits; This accumulator, its two ends spiral shell respectively are provided with a vinyl cover; This vinyl cover, it is respectively equipped with seal ring in the groove of cross axle exterior edge face, and the outer rim internal surface formation sealing shape with this vinyl cover is provided with an air hole at the center of vinyl cover.
The purpose of this utility model can also further realize by following technical measures.
The aforesaid universal coupling with spider that self has accumulator, wherein said air hole are designed to the very little air hole in aperture that oil is difficult for overflowing.
The aforesaid universal coupling with spider that self has accumulator, wherein said air hole is provided with non cohesive gel paper and is closed shape.
The aforesaid universal coupling with spider that self has accumulator, wherein said vinyl cover are transparent plastic cover.
The utility model compared with prior art has tangible advantage and good effect.By above technological scheme as can be known, owing to have an accumulator in cross axle, volume read-out can use six months greatly even be longer.It is that air is selected and is convenient to refuel in order to refuel that transparent plastic is stamped air hole.Under the action of centrifugal force that the oil of accumulator produces when coupling turns round, automatically diffuse to and need lubricated place to the oil transportation of cross oil circuit, and can be from the air hole leakage of oil.Cross oil circuit mouth in the cross axle places spring and check valve sheet does not influence oiling (oiling injection force energy against the force of the spring), and refuel finish after check valve sheet under spring force and oil pressure effect, seal tank filler sleeve, even plug screw is come off also not from the tank filler sleeve leakage of oil by vibration, thereby this universal coupling with spider that self has accumulator, a volume read-out not easy oil leakage greatly again, prolonged filling cycle, alleviate miantainers' labor intensity, relatively guaranteed the working life that coupling is used.The utility model is applicable to three kinds of canonical form universal coupling with spiders and other nonstandard product.
In sum, volume read-out of the utility model is big, lubricant oil can be used reached six months even the longer time, prolonged filling cycle greatly, and have reduce to refuel number of times, alleviate maintenance labor intensity, improve coupling working life and economical and practical effect.It is in limited field, technical development space, no matter structurally or bigger improvement all arranged on the function, and have large improvement technically, and produced handy and practical effect, and has the effect of enhancement really, thereby being suitable for practicality more, really is a new and innovative, progressive, practical new design.
