Specific embodiment
The utility model embodiment is described further below in conjunction with the accompanying drawings：
As shown in Figure 1, a kind of three ball pin assemblies, including including spider 1, the spider 1 includes frame body 11 and three
Root axis pin 12 is equipped with interior ball 2 on described every axis pin 12, it is each in be arranged with outer ball 3 outside ball 2, it is described
Interior ball 2 is sheathed on corresponding axis pin 12 and along it, axially sliding coordinates with the axis pin 12, the outer ball 3 and interior ball 2
It circumferentially rotates and coordinates along the axial wobble of the interior 2 place axis pin 12 of ball.The beneficial effects of the utility model are to eliminate rolling
Needle, and the space of needle roller imputed to the axis pin of spider, increase the diameter of axis pin in this way and axis pin and flower draw a bow to the full between hold cultivation
Area makes three ball pin assemblies that can bear higher torque, compared to three ball pin assemblies equipped with needle roller, avoid needle roller be crushed from
And cause the failure of three ball pin assemblies.The utility model directly sets two balls, can realize sliding of the ball with respect to axis pin, together
When can enable ball relative swing, increase the swing angle of product.The utility model also has simple in structure, assembling side
Just, reliable in action, easy to maintenance, the advantages that service life is long.
Outside axis pin 12 of the inner surface of the interior ball 2 for the inner surface of cylindrical, described interior ball 2 and where it
Surface fits.The interior ball of cylindrical form interior surface is steady when interior ball is slid with axis pin, ensures slippage.
The interior ball 2 outwardly convexes to form inner circle arc surface 21, the inner surface and inner circle of the outer ball 3
Arc surface 21 offsets.Specifically, the interior ball 2 outwardly convexes to form inner circle arc surface 21 as spherical surface.More specifically
Say, between the inner surface of the outer ball 3 and inner circle arc surface 21 be equipped with swing gap 22.Such structure causes outer ball
It is swung reliably with interior ball, and increases swing angle.
The inner surface of the outer ball 3 is cylindrical surface.Such structure so that the contact with interior ball of outer ball is one
Straight line, more conducively three ball pins are swung, while can reduce the abrasion of ball, it can also be made to bear the torque of bigger.
The outer surface of the outer ball 3 is outer circle arc surface 31.Specifically, the outer ball 3 is close to 11 one end of frame body
Outer circle arc surface 31 slope be more than far from 11 one end of frame body outer circle arc surface 31 slope.The setting of outer circle arc surface makes
It is sphere-contact to obtain contact of the outer ball with housing, reduces friction, reduces ball and wears so that long product lifecycle, and
The setting of Different Slope be based under different operating modes three ball pins abrasion and swing performance specific consideration so that product can be born more
Big torque reduces abrasion simultaneously so that long product lifecycle.
The every one end of axis pin 12 far from frame body 11 is equipped with slides limit stop ring 4 in place for interior ball 2.Limiting block
The setting of circle avoids inside and outside ball from crossing movement and unexpected, guarantee product safety performance occurs.
The length of the outer ball 3 is more than the length of interior ball 2, and the end of interior ball 2 is protruded at the both ends of the outer ball 3
Outside portion.Such structure causes the internal ball of outer ball to play certain protective effect, so that long product lifecycle.
