The inner ring seat 3 is detachably disposed in the receiving chamber 220 of the outer ring seat 2 along the axis L, and the inner ring seat 3 can rotate relative to the outer ring seat 2 at an angle oblique to the axis L. The inner ring seat 3 includes an inner wall surface 31 and an outer wall surface 32 which are oppositely arranged, the inner wall surface 31 surrounds and defines a connecting hole 30 for the shaft connection of the transmission shaft 91, and the connecting hole 30 is suitable for being jointed with the transmission shaft 91. The outer wall surface 32 has a plurality of spaced inner grooves 321, the inner grooves 321 penetrate through the top and the bottom and extend in the same direction as the outer grooves 224, the number of the inner grooves 321 is a factor of the number of the outer grooves 224, and the number of the inner grooves 321 is greater than or equal to three.
The retainer 4 is detachably disposed between the outer ring seat 2 and the inner ring seat 3 along the axis L, and the retainer 4 is rotatable with the inner ring seat 3 relative to the outer ring seat 2. The retainer 4 includes a plurality of through holes 41 spaced apart from each other and penetrating from the inner side to the outer side, the number of the through holes 41 is greater than or equal to three, in the first embodiment, the number of the through holes 41 is six, the through holes 41 respectively correspond to the inner groove 321 and the outer groove 224, and each through hole 41 faces one of the outer grooves 224 and one of the inner grooves 321.
The balls 5 are detachably mounted in the through holes 41 of the retainer 4, the balls 5 are arranged at equal intervals, each ball 5 is rollably accommodated between one of the inner grooves 321 of the inner ring base 3 and one of the outer grooves 224 of the outer ring base 2, the number of the balls 5 is a factor of the number of the outer grooves 224, the number of the balls 5 is greater than or equal to three, and the number of the balls 5 is not equal to the number of the outer grooves 224, in the first embodiment, the number of the balls 5 is three.

Referring to fig. 4 and 5, the outer grooves 224 of the outer ring seat 2 are regarded as two groups of regular triangular combinations, each group including three outer grooves 224. First, as shown in fig. 4, the balls 5 are accommodated in three of the through holes 41 and the corresponding three inner grooves 321, and then the balls 5 are aligned with one of the outer grooves 224 and installed in the outer ring seat 2. When the three outer grooves 224 are worn and cannot smoothly transmit, as shown in fig. 5, the user can take out the balls 5 and replace the balls in another set of outer grooves 224 and three other inner grooves 321, so that the ball bearing can be continuously used.
Referring to fig. 6, in a variation of the first embodiment, the number of the inner grooves 321 of the inner ring seat 3 is changed to three, and since the hardness of the inner ring seat 3 is higher than that of the outer ring seat 2, and the inner grooves 321 are less worn, the inner grooves 321 do not need to be replaced when the balls 5 are replaced, and thus, the inner grooves 321 can be used. For the same reason, the number of the through holes 41 of the retainer 4 can be three, and the retainer can be used continuously when being replaced.
Referring to fig. 7 and 8, a second embodiment of the present invention is shown, which is similar to the first embodiment, except that:
the number of the outer grooves 224 is eight, the number of the inner grooves 321 is eight, the number of the through holes 41 is eight, and the number of the balls 5 is four.
The outer grooves 224 are considered to be two sets of square-shaped combinations, each set containing four of the outer grooves 224. As shown in fig. 7, four balls 5 are firstly installed in four of the inner grooves 321 of the inner ring seat 3 and one set of the outer grooves 224 of the outer ring seat 2, and then the operation is completed. Subsequently, as shown in fig. 8, the user can replace the ball 5 with another four inner grooves 321 and another set of outer grooves 224 for further use, and this second embodiment also has the effect of increasing the service life by two times.
Referring to fig. 9, in a variation of the second embodiment, since the ball 5 can continue to use the inner groove 321 when being replaced, the number of the inner grooves 321 of the inner ring seat 3 is four, and the effect of increasing the service life by two times is also achieved.
It can be seen from the above variations that the number of the inner grooves 321 and the through holes 41 of the present invention may be equal to or different from the number of the outer grooves 224, and the variations are all within the scope of the present invention as long as the number of the inner grooves 321 and the through holes 41 can be correspondingly varied in accordance with the balls 5, so that each ball 5 can be stably installed in one of the inner grooves 321 and one of the outer grooves 224.
Referring to fig. 10 and 11, a third embodiment of the present invention is shown, which is similar to the first embodiment except that:
the number of the outer grooves 224 is twelve, the number of the inner grooves 321 is twelve, the number of the through holes 41 is twelve, and the number of the balls 5 is six.
The outer grooves 224 are considered to be two sets of regular hexagonal arrangements, each set containing six of the outer grooves 224. As shown in fig. 10, six balls 5 are firstly installed in six of the inner grooves 321 of the inner ring seat 3 and one set of the outer grooves 224 of the outer ring seat 2, and then the operation is completed. Subsequently, as shown in fig. 11, the user can replace the ball 5 with another six inner grooves 321 and another set of outer grooves 224 for further use, and this third embodiment also has the effect of increasing the service life by two times.
Referring to fig. 12, in a variation of the third embodiment, the number of the balls 5 is four, and the outer grooves 224 are regarded as three groups of combinations arranged in a square shape, each group including four outer grooves 224. Four balls 5 are firstly installed in four of the inner grooves 321 of the inner ring seat 3 and the first group of the outer grooves 224 of the outer ring seat 2, and then the operation is completed. Subsequently, the balls 5 can be sequentially replaced in the second set of the outer grooves 224 and the third set of the outer grooves 224 for further use, so that the service life of the ball bearing device can be improved by three times.
Referring to fig. 13, in another variation of the third embodiment, the number of the balls 5 is three, and the outer grooves 224 are regarded as four groups arranged in a regular triangle, each group includes three outer grooves 224. Three balls 5 are firstly installed in three of the inner grooves 321 of the inner ring seat 3 and the first group of the outer grooves 224 of the outer ring seat 2, and then the operation is performed. Then, the balls 5 can be sequentially replaced in the second set of the outer grooves 224, the third set of the outer grooves 224 and the fourth set of the outer grooves 224 for continuous use, thereby the service life of the invention can be increased by four times. It can be understood that, when the ball 5 is replaced, if the inner groove 321 and the through hole 41 are worn more, the inner groove 321 and the through hole 41 can be replaced at the same time, and the service life of the present invention can be improved.
As can be seen from the above-mentioned variations, the number of the balls 5 in the third embodiment is equal to or greater than three, the number of the balls 5 is not equal to the number of the outer grooves 224 and is a factor of the number of the outer grooves 224, and the balls 5 are arranged at equal intervals, i.e., the balls 5 have the same function of being used in groups.
In summary, the front wheel transmission steering apparatus of the present invention utilizes the number of the balls 5 less than the number of the outer grooves 224 and matches with the specific number condition, so that the balls 5 can be installed in one set of the outer grooves 224 of the outer ring seat 2 first, and then the balls 5 can be installed in the other set of the outer grooves 224 again for continuous use.
The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and the invention is still within the scope of the present invention by simple equivalent changes and modifications made according to the claims and the contents of the specification.
