Embodiment
As shown in Figure 1-Figure 3: a kind of spherical shell assembly, comprise ball pin 1 and spherical shell 3, described ball pin 1 comprises interconnective pin rod 10 and rolling ball 2, described pin rod 10 comprises the first step 11 connected successively, second step 12 and main paragraph 13, described first step 11 is connected by breeze way 14 with between second step 12, annular groove 15 is provided with between described second step 12 and main paragraph 13, the secondary section 132 that described main paragraph 13 comprises principal piece 131 and is connected with rolling ball 2, described secondary section 132 is connected by strengthening segment with rolling ball 2, described strengthening segment comprises interconnective first strengthening segment 134 and the second strengthening segment 135, the curved shape of outer wall of described first strengthening segment 134, the outer wall of the second strengthening segment 135 takes the form of inclined plane, the outer wall radian of this first strengthening segment 134 is π/10-π/8, described second strengthening segment 135 is fitted and connected with rolling ball 2, the diameter of described second strengthening segment 135 is greater than the diameter of principal piece 131, the outer wall of described rolling ball 2 there is the flat body 22 of terraced body 21 and terraced body 21 both sides by two circular groove 20 segmentations,
Comprise in described spherical shell 3 through connection bucket chamber 31 and ball chamber 32, described rolling ball 2 rolls with ball chamber 32 and is connected, described bucket chamber 31 is in funnel-like, and the setting of bucket chamber 31 facilitates the rolling ball 2 of ball pin 1 to stretch in ball chamber 32, and further facilitate to circular groove 20 topping-up.Be provided with ball seat 4 bottom described ball chamber 32, this ball seat 4 is provided with the foundation trench 40 coordinating rolling ball 2 to roll, and what this foundation trench 40 inwall offers corresponding two circular grooves 20 agrees with groove 41, and agreeing with groove 41 is means of complementary annular groove 20 oils in reserve.The bottom of described spherical shell 3 is connected with stifle 5, between this stifle 5 and ball seat 4, is provided with belleville spring 6.Belleville spring 6 can alleviate and operationally produces active force to stifle 5 in ball pin 1, and can improve the sealing between stifle 5 and ball seat 4 further, reduces outer member influence power, ensures the stability that ball pin 1 works.
