Abstract
The invention relates to a nut, in particular to a radial high-pressure retaining nut, and belongs to the technical field of retaining nuts. The technical scheme is that: the radial high-pressure retaining nut comprises an inner sleeve, wherein a connecting hole which runs through the inner sleeve is formed in a central area in the inner sleeve; a shell is arranged at one end of the inner sleeve, and a locknut is arranged at the other end of the inner sleeve; the locknut and the shell are sleeved on the inner sleeve and are in fastened connection with the inner sleeve; and an oil injection hole is formed in the inner sleeve corresponding to the outer side with the connecting hole, and a sealing plug for sealing the oil injection hole is arranged at one end of the oil injection hole corresponding to the locknut. The inner sleeve is connected with a supporting surface of a screw through the shell, and the other end of the inner sleeve is pressed against the locknut; the oil injection and pressurization are performed through the oil injection hole, and a thread of the inner sleeve corresponding to the inner wall of the connecting hole is connected with a tightening thread of the screw, so that the non-rotation between the connected inner sleeve and the screw is ensured; and the retaining nut has a simple and compact structure, is convenient to install and use, and is reliable in connection, and the pretightening force is increased.
Description
Technical field
The present invention relates to a kind of nut, especially a kind of radially high pressure retainer nut belongs to retainer nut's technical field.
Background technique
In Machine Components and Parts Design, often need link together two or several part or parts, generally adopt bolt to connect, and under and the situation that intensity is severe relatively more frequent in vibrations, the pretightening force of spring pad is difficult to fasten fully.Therefore, the connection effect is very undesirable.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the existing technology, a kind of radially high pressure retainer nut is provided, it is simple and compact for structure, and is easy to install, improves pretightening force, connects reliable.
According to technological scheme provided by the invention, said radially high pressure retainer nut comprises interior cover, the attachment hole that the centre area in the said interior cover is overlapped in being provided with and connecting; One end of interior cover is provided with shell, and the other end of interior cover is provided with locking nut; Put in said locking nut and shell are enclosed within, and be fastenedly connected with interior cover; In cover be provided with oil hole corresponding to the outside that attachment hole is set, said oil hole is corresponding, and to be provided with the sealing that is used to seal oil hole stifled with the corresponding end of locking nut.
The axis of said oil hole and the axis of attachment hole parallel.Cover is provided with corresponding to an end end that links to each other with shell and is connected step in said, and interior cover is through connecting the corresponding cooperation with shell of step.
Be provided with first sealing gasket and an O type circle between said shell and the bottom that is connected step.Be provided with second sealing gasket and the 2nd O type circle between cover and shell in said, said the 2nd O type circle and second sealing gasket are positioned at cover and connect the outer surface of step corresponding to being provided with.
Cover is provided with equally distributed installing and locating hole corresponding to the outer ring that attachment hole is set in said.The end edge setting of the said locking nut outer ring hole that is located by connecting.Said sealing is stifled is embedded in the cover, and sealing is stifled corresponding to the end in the cover in stretching into the 3rd O type circle is set.
Advantage of the present invention: an end of interior cover is provided with the connection step, and interior cover is fastenedly connected after connecting step and shell corresponding matching; Interior cover is fastenedly connected corresponding to the other end that links to each other with shell and locking nut, in the interior cover oil hole is set; Interior cover links to each other with the supporting surface of screw rod through shell, and the other end of interior cover withstands through locking nut; Through oil hole oiling pressurization, the screw thread through the corresponding attachment hole inwall of interior cover is threaded with the screw rod tension, after cover connects in guaranteeing and not rotating between screw rod; Simple and compact for structure, easy to install, improve pretightening force, connect reliable.
