Abstract
The invention relates to a three-groove shell, in particular to an end recessed three-groove shell. The end recessed three-groove shell comprises a three-groove shell body and a three-groove shell handle; three grooves are uniformly distributed in the three-groove shell body; grooves are formed in the middle parts of contact surfaces of the grooves with ring balls; and lubricating oil can be stored in the grooves for a long time, so that the lubrication effect of the three-groove shell and the ring balls is guaranteed, the wear is reduced, and the service life is prolonged.
Description
Technical field
The present invention relates to a kind of three pot shells, particularly a kind of end concave three pot shell.
Background technique
Existing constant velocity driving shaft assembly all comprises three pot shells, and three pot shell inside are provided with equally distributed three raceway grooves, during use, globally to move in raceway groove.Global and raceway groove, through using for a long time, often there will be wearing and tearing, impacts use, even globally sometimes breaks, and for this problem, simple dependence uses Lubricants to increase lubrication and can not solve.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of reasonable in design, can reduces three pot shells and global wearing and tearing, the three pot shell devices increased the service life.
The present invention includes three pot shell main bodys, three pot shell handle bodies, described three pot shell body interior are provided with equally distributed three raceway grooves, and in the middle part of the surface of contact that described raceway groove and ball contact, indent forms groove, and described groove and surface of contact joint are with arc transition.
Further, the radian of described surface of contact is identical to radian with global spherical axis.
Further, described depth of groove is 0.5-5mm, and width is 0.5-5mm.
Further, described three pot shell main bodys and three pot shell handle body joints are provided with stepped shaft reinforcement structure.
Further, described three pot shell body end and dust-proof cover joint are provided with cylindrical boss, and described boss and dust-proof cover match.
The present invention's indent in the middle part of raceway groove and the global surface of contact contacted defines groove, groove can store lubricant oil, and can be long-term lubricant oil is remained on wherein, simultaneously, the impurity that sandstone, iron filings etc. are harder to be brought in groove and to be contained in wherein in the process of global motion, both substantially increases lubrication effect, and again reduces wearing and tearing, decrease the hard impurity such as sandstone, iron filings to three pot shells with globally cause damage, extend working life.
The present invention compared with the existing technology has the following advantages and effect:
1, reduce three pot shells and global wearing and tearing, extend working life;
2, three pot shells and global ability to bear is added;
3, maintenance maintenance is with low cost;

Embodiment
Below in conjunction with embodiment, the present invention is described in further detail, and following examples are explanation of the invention and the present invention is not limited to following examples.
Embodiment 1: as shown in Figure 1 and Figure 2, the present embodiment comprises three pot shell main body 1, three pot shell handle bodies 2, three pot shell main body 1 inside are provided with three raceway grooves 3 evenly arranged, raceway groove 3 and the global surface of contact 4 contacted are provided with the groove 5 to three pot shell main body 1 direction indents, and groove 5 and surface of contact 4 joint are with arc transition.After installation, global motion in raceway groove 3, lubricant oil enters groove 5 extended stationary periods wherein, ensure that surface of contact 4 and be globally in lubricating status all the time, the hard impurity such as sandstone, iron filings also can be moved in groove 5 along with global, while greatly improving greasy property, decrease wearing and tearing, extend working life.
Embodiment 2: in the present embodiment, the radian of surface of contact 4 is identical to radian with global spherical axis, ensure that global and three pot shells fit tightly, changing point cantact is face contact, increase area of contact, lubricant oil forms complete oil film between, further increases lubricating ability and antiwear property, improve lubrication effect and decrease three pot shell main bodys 1 and global wearing and tearing, adding three pot shell main bodys 1 and global ability to bear.
Embodiment 3: in the present embodiment, and the degree of depth of groove 5 is 0.5-5mm, and width is 0.5-5mm.The degree of depth and the width of groove 5 are larger, it is more that lubricant oil stores, greasy property is better, but when excessive, because global groove 5 part that is positioned at does not stress, cause discontinuity that is global and three pot shells, also can cause wearing and tearing on the contrary, the integral hardness of three pot shell main bodys 1 also can be made in addition to be affected.It is proper for as the case may be the degree of depth of groove 5 and width being arranged on 0.5-5mm.
Embodiment 4: in the present embodiment, three pot shell main bodys 1 and three pot shell handle body 2 joints are also provided with stepped shaft and strengthen structure 6, stepped shaft is strengthened structure 6 and the connection of three pot shell main bodys 1 and three pot shell handle bodies 2 can be made firmer, is not easy fracture, further increases the working life of three pot shells.
Embodiment 5: in the present embodiment, end and the dust-proof cover joint of three pot shell main bodys 1 are provided with cylindrical boss 7, cylindrical boss 7 size and dust-proof cover match, make both laminatings tightr like this, ensure that the using effect of dust-proof cover, contribute to preventing dust from entering three pot shells, less wearing and tearing.
In addition, it should be noted that, the specific embodiment described in this specification, the shape, institute's title of being named etc. of its parts and components can be different.All equivalences of doing according to structure, feature and the principle described in inventional idea of the present invention or simple change, be included in the protection domain of patent of the present invention.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment; only otherwise depart from structure of the present invention or surmount this scope as defined in the claims, protection scope of the present invention all should be belonged to.
