In above-mentioned plane bearing, the axis of described needle roller two is parallel with the axis of locating stud, and is provided with a retainer two between locating stud and the hole wall of positioning hole, and described needle roller two is arranged in described retainer two.Limit the position of two pairs of needle rollers two of retainer, makes each needle roller two can be evenly distributed, and the circumferential mass distribution of bearing evenly, each needle roller two load of bearing is also identical.
In above-mentioned plane bearing, on described support plate two, offer an annular mounting groove, described retainer one is arranged in described mounting groove.Because the support plate one of this plane bearing is connected with positioning hole by locating stud with support plate two, without the structure that other are set on support plate one and support plate two, position, the structure of having simplified support plate one and support plate two, has also facilitated the assembling of this plane bearing.
In above-mentioned plane bearing, the outer side surface of the outer side surface of described support plate one and support plate two is equipped with an installation base.Support plate one is fixed with the link that is connected this plane bearing by this positioning boss with support plate two.
In above-mentioned plane bearing, described needle roller one has 24, and described needle roller two has 6.
Compared with prior art, the utlity model has following advantage;
1, in order to make support plate one and support plate two can bear larger radial force, center position at support plate one is provided with a locating stud, this locating stud is plugged in the positioning hole on support plate two, between locating stud and positioning hole, be provided with some needle rollers two, can improve the transmission stability of this plane bearing.
2, locating stud and needle roller two have increased the ability to bear of the radial load of this bearing, and axial force also has needle roller one and needle roller two shareds, and the bulk strength of this bearing is improved, and effectively extend working life.
3, the support plate one due to this plane bearing is connected with positioning hole by locating stud with support plate two, without the structure that other are set on support plate one and support plate two, position, the structure of having simplified support plate one and support plate two, has also facilitated the assembling of this plane bearing.
