Bearing roller central axis is arranged symmetrically with, and becomes 25 with bearing roller central axis0Angle.
Further, the top of described arm body arranges connecting portion, the centrally disposed connection through hole of described connecting portion.
Further, described arm body is that one end is big, the triangular structure that the other end is little, and wherein stub end is with bearing outer ring even
Connecing, little head end is connected with connecting portion.
Further, described connection through hole is circular port.
Further, described bearing roller is inlaid in retainer, and be provided with in the both sides of bearing roller with
The dust-blocking ring that bearing outer ring and bearing inner race connect.
Further, described bearing outer ring is provided with the outer ring draw-in groove of fixing dust-blocking ring in the both sides of bearing outer ring slot rolling.
Further, described bearing inner race is provided with the inner ring draw-in groove of fixing dust-blocking ring in the both sides of bearing inner race slot rolling.
Compared with prior art, the invention has the beneficial effects as follows: the structure of the structure particularly operation part of bearing sets
Meter reasonability, the effectiveness of countershaft acknowledgement of consignment row and stability tool have a significant impact, and bearing run whether stablize, direct shadow
Ring the operational effect of whole set equipment, for bearing used by machine head of embroidery machine linkage, according to actually used scene, bearing is rolled
Son runs with the roller of bearing internal external circle and improves coordinating of raceway groove, goes out when effectively prevent the work of existing machine head of embroidery machine
Existing axial runout phenomenon, preferably improves the operation stability of machine head of embroidery machine linkage.

Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, right
The present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, not
For limiting the present invention.
As Figure 1-4, the present invention relates to a kind of embroidery machine connecting rod special bearing, including bearing outer ring 1 and bearing inner race
2, it is provided with bearing roller 4 between described bearing outer ring 1 and bearing inner race 2, and is provided with bearing outer ring at the medial surface of bearing outer ring 1
Slot rolling 9, outer arc face connects an arm body 6, and the lateral surface at bearing inner race 2 is provided with bearing inner race slot rolling 11, and described bearing rolls
Son 4 is spheroplast, and described bearing outer ring slot rolling 9 and bearing inner race slot rolling 11 are arc groove, and bearing roller 4 and bearing outer ring
