Abstract
The utility model relates to a mute slid platform that is used for a car constant velocity cardan joint periodic-cycling service life test platform, which comprises a slid platform main body, wherein, a nylon slide rail (8) is added between an upper metal slide rail and a lower metal slide rail of the slid platform main body; the nylon slide rail (8) is connected with the upper metal slide rail (7), and the upper metal slide rail (7) is connected with a rotation part (1) of the slid platform through a bolt; the lower metal slide rail (9) is connected with a slid platform base (4) through a bolt; both of the upper and the lower metal slide rails are of an arc shape. Since the nylon slide rail with a mute function is added between the upper and the lower metal slide rails, and the friction between the upper and the lower metal slide rails is transformed to be the sliding friction between the nylon slide rail and the lower metal slide rail, so that the noise is smaller, and even no noise exists; the nylon slide rail is of a flat structure, and the nylon slide rail is contacted with the lower metal slide rail in face-face way, thereby not only being convenient to be locked and to stably turn around, but also having homogenous stress, thereby realizing the mute turn-around movement of a heavy load slid platform.
Description
Technical field
The utility model relates to testing table, particularly relates to a kind of quiet slide unit that is used for CV joint for car loop cycle life test rack.
Background technology
Rotary table structural volume in the CV joint for car loop cycle life test rack is big, Heavy Weight, friction and noise in the time of should not between rail plate and rotary table, adopting roll structure to reduce table revolving movement, in addition, ball slide unit structure can't be locked the significant deficiency of rotary table in addition.If rotary table can't be locked, during testing table work, the powerful vibration of the heavy-duty motor on the rotary table can make rotary table take off lock, causes peril.Also have, general slide unit adopts the structure that ball is set for friction and the noise that reduces between the metal slide rail between upper and lower arc-shaped slide rail, and the shortcoming of this structure is: the one, and upper and lower slide rail and ball are to contact, contact area is little, is not suitable for bearing heavy load; The 2nd, because contact area is little, can't lock between the upper and lower slide rail.
Therefore, must design a kind of can making has big surface of contact between the slide rail, be convenient to lock rotary table and bear heavy load, makes friction and the minimum slide unit structure of noise between the slide rail again.A kind of quiet slide unit that is used for CV joint for car loop cycle life test rack that the utility model relates to is exactly the slide unit with these two kinds of design features.
Summary of the invention
Technical problem to be solved in the utility model is: at the prior art defective, provide a kind of structure simple relatively, the quiet slide unit that is used for CV joint for car loop cycle life test rack stable and reliable for performance.
The technical scheme that its technical matters that solves the utility model adopts is: comprise the slide unit main body, between the slide rail of metal up and down of its slide track component, increase a nylon slide rail, wherein, the nylon slide rail links to each other with last metal slide rail, last metal slide rail links to each other with the slide unit pivotable parts with bolt, and following metal slide rail links to each other with the slide unit base with bolt; Two metal slide rails all are arcs.
The utility model compared with prior art has following main beneficial effect:
One. having adopted increases the new structure with nylon slide rail of quiet effect in upper and lower metal slide rail.The nylon slide rail is to make with nylon material, and it is fixed on the metal slide rail, can move with last metal slide rail.When gyration was done in slide unit moving part wraparound rotating shaft, the friction between the upper and lower metal slide rail just became the sliding friction between nylon slide rail and the following metal slide rail, so noise is little, even does not have noise.
They are two years old. and the nylon slide rail is a slab construction, is that face-face contacts with following metal slide rail, is convenient to locking.
They are three years old. the nylon slide rail is with after following metal slide rail employing face contacts, and not only the slide rail surface of contact is big, revolution steadily, and stressed evenly, thereby realized the quiet gyration of heavy load slide unit.
Description of drawings
Fig. 1 is the front view of structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the structure enlarged diagram of slide track component 3 among Fig. 1.
Among the figure: 1. slide unit pivotable parts; 2. slide unit locking device; 3. slide track component; 4. slide unit base; 5. slide unit rotating shaft; 6. slide unit hydraulic pressure pull bar; 7. go up the metal slide rail; 8. nylon slide rail; 9. descend the metal slide rail.
Embodiment
The quiet slide unit that is used for CV joint for car loop cycle life test rack that the utility model provides, comprise the slide unit main body, concrete structure is as depicted in figs. 1 and 2: described slide unit main body increases a nylon slide rail 8 between the slide rail of metal up and down of its slide track component 3.Wherein, nylon slide rail 8 links to each other with last metal slide rail 7, and last metal slide rail 7 usefulness bolts link to each other with slide unit pivotable parts 1; Following metal slide rail 9 usefulness bolts link to each other with slide unit base 4; Two metal slide rails all are arcs.
As shown in Figure 3: described nylon slide rail 8 is slab constructions, is face-face with following metal slide rail 9 and contacts.
The slide unit main body is a prior art, mainly is made up of slide unit pivotable parts 1, slide unit locking device 2, slide track component 3, slide unit base 4 and slide unit hydraulic pressure pull bar 6.Slide unit pivotable parts 1 connects by slide track component 3 with slide unit base 4.Slide unit pivotable parts 1 is under the effect of slide unit hydraulic push rod 6, (concrete angle is determined according to testing requirements can to turn round certain angle around slide unit rotating shaft 5, maximum angle can reach 45 degree), after 1 revolution of slide unit pivotable parts puts in place, slide unit locking device 2 is with slide track component 3 lockings, and this has just realized the locking with slide unit moving part 1 and slide unit base 4.
During the utility model work, can between nylon slide rail 8 and following metal slide rail 9, coat lubricating oil, when slide unit turned round, the friction between nylon slide rail 8 and the following metal slide rail 9 was the face contact friction of metal and nylon material, and not only friction factor is little, there is not noise, and the slide rail surface of contact is big, and revolution steadily, and is stressed even, be convenient to locking, this has just realized the quiet gyration of heavy load slide unit.
