Abstract
The utility model relates to a three pot shells, especially a three pot shells of tip indent formula. The utility model discloses a three pot shell main parts, the three pot shell handles body, the inside three channel that is equipped with evenly distributed of three pot shell main parts, contact surface middle part that channel and the earth contacted sets up the recess, and the recess can long -term storage lubricating oil, has guaranteed the lubricated effect of three pot shells with the earth, and reducing wear has lengthened life.
Description
Technical field
This utility model relates to a kind of three pot shells, particularly a kind of end concave three pot shell.
Background technology
Existing constant velocity driving shaft assembly all includes three pot shells, is provided with equally distributed three raceway grooves inside three pot shells, during use, and global motion in raceway groove., through using for a long time, often there is abrasion, use is impacted in global and raceway groove, and even global sometimes breaks, and for this problem, simple dependence uses lubricating fluid to increase lubrication and can not solve.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of reasonable in design, can reduce three pot shells and global abrasion, the three pot shell devices increased the service life.
This utility model includes three pot shell main bodys, three pot shell shank body, and described three pot shell body interior are provided with equally distributed three raceway grooves, and in the middle part of the contact surface that described raceway groove and ball contact, indent forms groove, and described groove and contact surface junction are with arc transition.
Further, the radian of described contact surface is identical with the axial radian of global sphere.
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 shank body junctions are provided with stairstepping reinforcement structure.
Further, described three pot shell body end and dust cover junction are provided with cylindrical boss, and described boss and dust cover match.
This utility model indent in the middle part of raceway groove and the global contact surface contacted defines groove, groove can store lubricating oil, and can be long-term lubricating oil is remained at, simultaneously, the harder impurity such as sandstone, iron filings can be brought in groove and contained therein in the process of global motion, had both substantially increased lubricant effect, and had reduced again abrasion, decrease the hard impurity such as sandstone, iron filings and to three pot shells and global cause damage, extend service life.
This utility model compared with the existing technology has the following advantages and effect:
1, reduce three pot shells and global abrasion, extend service life；
2, three pot shells and global ability to bear are added；
3, maintenance maintenance is with low cost；
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.

Detailed description of the invention
Below in conjunction with embodiment, this utility model being described in further detail, following example are that this utility model is not limited to following example to explanation of the present utility model.
Embodiment 1: as shown in Figure 1 and Figure 2, the present embodiment includes three pot shell main body 1, three pot shell shank body 2, three pot shell main bodys 1 are internal is provided with three raceway grooves 3 being uniformly arranged, raceway groove 3 and the global contact surface 4 contacted are provided with the groove 5 to three pot shell main body 1 direction indents, and groove 5 and contact surface 4 junction are with arc transition.After installation, global motion in raceway groove 3, lubricating oil enters groove 5 also extended stationary periods wherein, ensure that contact surface 4 and global be in lubricating status all the time, the hard impurity such as sandstone, iron filings is moved in groove 5 as well as global, while being greatly improved greasy property, decrease abrasion, extend service life.
Embodiment 2: in the present embodiment, the radian of contact surface 4 is identical with the axial radian of global sphere, ensure that global and three pot shells fit tightly, changing point cantact is face contact, increasing contact area, lubricating oil forms complete oil film between, further increases lubricating ability and antiwear property, improve lubricant effect and decrease three pot shell main bodys 1 and global abrasion, adding three pot shell main bodys 1 and global ability to bear.
Embodiment 3: in the present embodiment, the degree of depth of groove 5 is 0.5-5mm, and width is 0.5-5mm.The depth and width of groove 5 are more big, it is more many that lubricating oil stores, greasy property is more good, but when excessive, owing to global groove 5 part that is positioned at is not affected by power, cause global and three pot shells discontinuity, will also result in abrasion on the contrary, the integral hardness of three pot shell main bodys 1 additionally also can be made to be affected.It is proper for as the case may be the depth and width of groove 5 being arranged on 0.5-5mm.
Embodiment 4: in the present embodiment, three pot shell main bodys 1 and three pot shell shank body 2 junctions are additionally provided with stairstepping reinforcement structure 6, stairstepping reinforcement structure 6 can so that the connection of three pot shell main bodys 1 and three pot shell shank body 2 be firmer, it is not easy to fracture, further increases the service life of three pot shells.
Embodiment 5: in the present embodiment, the end of three pot shell main bodys 1 and dust cover junction are provided with cylindrical boss 7, and cylindrical boss 7 size and dust cover match, so make both laminatings tightr, ensure that the result of use of dust cover, contribute to preventing dust from entering three pot shells, less abrasion.
Furthermore, it is necessary to illustrate, the specific embodiment described in this specification, the shape of its parts and components, be named title etc. can be different.All equivalences done according to the structure described in this utility model inventional idea, feature and principle or simple change, be all included in the protection domain of this utility model patent.Described specific embodiment can be made various amendment or supplements or adopt similar mode to substitute by this utility model person of ordinary skill in the field; without departing from structure of the present utility model or surmount the scope that present claims book is defined, protection domain of the present utility model all should be belonged to.
