Abstract
The utility model discloses a three-column groove shell, and aims at providing a three-column groove shell which is provided with a cylindrical external surface at one end, can simplify the processing technology of a dustproof cover, reduces the production cost of the dustproof cover, can effectively avoid oil leakage, and improves the sealing performance of assembly. The three-column groove shell comprises a three-column groove shell body. The dustproof cover is in sleeved connection with the external surface of the three-column groove shell body, the external surface of the joint of the three-column groove shell body and the dustproof cover is a cylinder surface matched with the internal surface of the dustproof cover, and a transition cambered surface is arranged between the cylinder surface and the external wall of the three-column groove shell body. Three channels which are evenly distributed along the circumference are arranged in the three-column groove shell body, and a chamfer is positioned between adjacent channels. The three-column groove shell improves an existing circular groove structure of the external surface of the three-column groove shell body, designs the external surface of the joint of the three-column groove shell body and the dustproof cover into the cylindrical surface so that the cylindrical surface can be matched with the internal surface of the dustproof cover much better, can effectively avoid oil leakage, and improves the sealing performance of assembly.
Description
Technical field
The utility model relates to a kind of universal joint parts, the housing on particularly a kind of tripod universal joint.
Background technique
At present, as shown in Figure 2, the inside of the housing body 2 on the three ball pin style universal joint is provided with three raceway grooves 3, be used to connect three ball pin bearings, and the external structure form is on the basis of cylndrical surface, between two raceway grooves 3, be provided with along equally distributed three circular grooves 5 of circumference, to reach under the prerequisite that does not influence intensity, the purpose that alleviates quality and reduce cost.But in the existing structure, usually will be at housing external mounting dust-proof cover, because existing housing external surface shape relative complex, make the interface shape of dust-proof cover to fit like a glove with the housing profile of housing, in the fashionable space that occurs of cover, therefore cause assembling back leakage of oil easily, the problem of sealing difference.
Patent Office of the People's Republic of China on November 17th, 2010 announced the utility model patent that name is called a kind of tripod universal joint, and notification number is 201636225U.This tripod universal joint comprises housing, three ball pin assemblies and three ball pin back-up rings, three ball pin assemblies are installed in the housing, three ball pin back-up rings are provided with opening, three ball pin back-up rings are embedded in the housing, and the part that three ball pin back-up rings pass the housing alley matches with the shape of housing alley.This model utility is improved the shape and the mounting point of three ball pin back-up rings, but the external shape of housing does not change, its outside is distributed with three circular grooves, make when dust-proof cover is installed, there is big space between housing and the dust-proof cover, cause assembling back leakage of oil easily, the problem of sealing difference.
Summary of the invention
The purpose of this utility model is that the housing outer surface that solves existing three ball pin style universal joint is provided with circular groove, cause the problem of leakage of oil and sealing difference behind the installation dust-proof cover easily, it is the cylndrical surface that an a kind of end outer surface is provided, can simplify the dust-proof cover processing technology, reduce the dust-proof cover cost of production and can effectively prevent oil leakage phenomenon, improve the housing of fitting tight.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of housing, comprise the housing body, be socketed with dust-proof cover on this external surface of housing, the outer surface of described housing body and dust-proof cover joint is and the suitable cylndrical surface of dust-proof cover internal surface.The utility model is designed to the cylndrical surface with the outer surface of housing body and dust-proof cover joint, make its cross section become a full circle, thereby better match with the dust-proof cover internal surface, eliminated the space between the housing body and dust-proof cover in the original structure, can effectively prevent leakage of oil, and improve the sealing of assembling.Whole relatively housing is the product of full circle, has alleviated weight again as much as possible, has simplified the processing of dust-proof cover simultaneously, reduces the cost of dust-proof cover.
As preferably, be provided with the transition cambered surface between described cylndrical surface and the housing body outer wall.The transition cambered surface plays transitional function between the two, can effectively eliminate cylndrical surface and housing body because the different wedge angles that cause of size.
As preferably, described housing body interior is provided with three raceway grooves, and described three raceway grooves evenly distribute along circumference.The housing body interior is provided with three raceway grooves, and in order to connect three ball pin bearings, three raceway grooves evenly distribute along circumference, makes between the bearing location more accurate.
As preferably, the joint of described housing body interior adjacent channel is provided with chamfering.The installation that convenient three ball pin bearings are set of chamfering.
The utility model has improved the structure of original this external surface of housing circular groove, the one end outer surface that will be connected with dust-proof cover is designed to the cylndrical surface, make the internal surface of its better matching dust-proof cover, can effectively prevent oil leakage phenomenon, sealing when having improved assembling, simplify the processing technology of dust-proof cover simultaneously, reduced the processing cost of dust-proof cover.
