Brief description
Fig. 1 is the cross-sectional schematic of one embodiment of the utility model.
Fig. 2 is the cross-sectional schematic of double ditch transmission sections of one embodiment of the utility model.
Fig. 3 is the schematic side view of double ditch transmission sections of one embodiment of the utility model.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：As illustrated, a kind of efficient double-cage super large pivot angle
Universal joint, including the outer cage 9 being mutually adapted and interior cage 8, described outer cage 9 includes being slidably matched in flange shell 1 and described flange shell 1
The first retainer 2, described interior cage 8 includes the second retainer 4；Described first retainer 2 inner chamber is provided with the double ditches being slidably matched
Transmission section 3, described pair of ditch transmission section 3 inner chambers are provided with described second retainer 4 being slidably matched.
As preferred, outer cage can be from the outer cage of VL type（I.e. concertina type universal joint）Both it had been provided that 20 ° of pivot angles, and can carry again
For 40mm about stroke, and interior cage can choose cage in RF type（I.e. fixed universal joint）It is provided that 47 ° of pivot angle.And it is double
Ditch transmission section is connected to the power transmission of outer cage and interior cage, preferably, the first raceway groove 211 and the second raceway groove 421 is concentric sets
Put so that cage all does pivot angle so that outer cage and interior cage combine centered on point O in the outer cage of VL type and RF type, it is to avoid
Compound tense increases the free degree that cage transmits end and Partner.The flexible of this double-cage universal joint is provided by the outer cage of VL type, stretches
Contracting amount is 40mm, and pivot angle then has cage in the outer cage of VL type and RF type jointly to provide, when cage stretches, maximum pendulum angle up to
47°+20°=67°.The utility model provides a kind of efficient double-cage super large pivot angle universal joint, including the outer cage being mutually adapted and interior
Cage, outer cage includes the first retainer being slidably matched in flange shell and flange shell, and interior cage includes the second retainer；First retainer
Inner chamber is provided with the double ditch transmission sections being slidably matched, and double ditch transmission section inner chambers are provided with the second retainer being slidably matched.Set in housing
There is the maximum angle that two retainer guarantees each other by the transmission section cooperation of double ditches can be slided, structure is simple, using effect
Good.The pivot angle during work of double-cage universal joint, by outer cage and interior cage shared, reduces steel ball sliding amplitude in channels,
While making cage turn to more smooth, also mitigate the abrasion to raceway groove for the steel ball, improve the service life of cage.Safety coefficient
High.During universal joint operating, because when various operating mode reason leads to pivot angle clamping stagnation, driving-shaft assembly will be unable to transmit power, causes
Exploration on Train Operation Safety.And this universal joint is because pivot angle is by cage shared in the outer cage of VL type and RF type, even if one of which raceway groove
Clamping stagnation, another set raceway groove is still provided that pivot angle, safer.
In the utility model, as illustrated, described first retainer 2 is provided with the first spin 21, described pair of ditch transmission
Save 3 outer walls and be provided with the first raceway groove 211 being slidably matched with described first spin 21.Certainly flange shell inwall also should be provided with for
The raceway groove being slidably matched with the first spin, is prior art, repeats no more.
In the utility model, as illustrated, being provided with inner race 41, described second retainer 4 in described second retainer 4
It is provided with the second spin 42, described pair of ditch transmission section 3 inwalls are provided with the second raceway groove 421 being slidably matched with described second spin.
It is additionally provided with inner race in second retainer, inner race also is provided with the raceway groove being slidably matched with described second spin.
In the utility model, as illustrated, described outer cage 9 is concertina type universal joint.
In the utility model, as illustrated, described interior cage 8 is fixed universal joint.
In the utility model, as illustrated, described first raceway groove 211 and the concentric setting of described second raceway groove 421.Fortune
Row is more steady.
In the utility model, as illustrated, correspond to described first retainer 2 in described flange shell 1 and hold axially back and forth dividing
It is not provided with the first catch spring 15 and the second catch spring 16.By two catch springs, the first retainer is carried out spacing, structure is simple, assembling side
Just.
