Abstract
The utility model discloses ball universal coupling, it comprises: flange seat (1), be installed on flange seat ring gear (2), be installed on external tooth cover (3) inside flange seat and ring gear, axle (7) is established in described external tooth cover, be provided with multiple ball rollers (4) of transmitting torque between described ring gear and external tooth cover, the end of described ring gear is provided with by the fixing end cap (6) of bolt (5).The beneficial effects of the utility model are: by the position of multiple ball roller, ring gear be connected with external tooth cover and transmit larger torque, because tooth designing and calculating is umbilical point contact stress, its admissible value proof stress value that is more curved than other, that turn round state is much higher, therefore can transmitting torque be improved, again because its contact is ball roller, therefore its friction ractor is little, efficiency is high, rotate freely, general axis knuckle 0-10 °.
Description
Technical field
The utility model relates to coupling, especially relates to a kind of ball universal coupling.
Background technique
At present, the universal coupling with spider of extensive use in China's mechanical transmission fields, through updating, its transmission capacity is enhanced, but still can not meet the requirement in mechanical transmission ability and working life.
Model utility content
The purpose of this utility model is exactly to solve the problem, and provides a kind of ball universal coupling, and its transmission capacity is large, long service life.
To achieve these goals, the utility model adopts following technological scheme:
Ball universal coupling, it comprises: flange seat (1), be installed on flange seat ring gear (2), be installed on external tooth cover (3) inside flange seat and ring gear, axle (7) is established in described external tooth cover, it is characterized in that, be provided with multiple ball rollers (4) of transmitting torque between described ring gear and external tooth cover, the end of described ring gear is provided with by the fixing end cap (6) of bolt (5).
The utility model has following beneficial effect: by the position of key component multiple ball roller, ring gear be connected with external tooth cover and transmit larger torque, because tooth designing and calculating is umbilical point contact stress, its admissible value proof stress value that is more curved than other, that turn round state is much higher, therefore can transmitting torque be improved, again because its contact is ball roller, therefore its friction ractor is little, efficiency is high, rotate freely.General axis knuckle 0-10 °.
Accompanying drawing explanation
Fig. 1 is ball universal coupling structural representation.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with specific embodiment, setting forth the utility model further.
As shown in Figure 1, ball universal coupling, it comprises: flange seat 1, be installed on flange seat ring gear 2, be installed on external tooth cover 3 inside flange seat and ring gear, axle 7 is established in described external tooth cover, it is characterized in that, be provided with multiple ball rollers 4 (ring gear and external tooth cover corresponding position are provided with the groove/opening with ball rollers co-operate) of transmitting torque between described ring gear and external tooth cover, the end of described ring gear is provided with by the fixing end cap 6 of bolt 5.
By multiple ball roller, ring gear be connected with external tooth cover and transmit larger torque (playing key effect), because tooth designing and calculating is umbilical point contact stress, its admissible value proof stress value that is more curved than other, that turn round state is much higher, therefore can transmitting torque be improved, again because its contact is ball roller, therefore its friction ractor is little, efficiency is high, rotate freely.General axis knuckle 0-10 °.
The foregoing is only preferred implementation of the present utility model, protection domain of the present utility model is not limited in above-mentioned mode of execution, and every technological scheme belonging to the utility model principle all belongs to protection domain of the present utility model.For a person skilled in the art, the some improvement carried out under the prerequisite not departing from principle of the present utility model, these improvement also should be considered as protection domain of the present utility model.
