Abstract

The utility model discloses a double-integral-bearing driving cam structure, which comprises a bearing large connecting rod, a flange bearing outer ring and a main shaft, wherein the main shaft is integrally provided with an upper bearing double-integral-cam connecting rod inner ring and a lower bearing double-integral-flange inner ring; a plurality of balls are arranged between the large bearing connecting rod and the inner ring of the upper bearing double-integral cam connecting rod and between the outer ring of the flange bearing and the inner ring of the lower bearing double-integral flange; has the advantages that: the utility model has the advantages of the practicality, low in production cost, novel structure, the setting of two whole cam connecting rod inner circles of upper bearing and the two whole flange inner circles integrated into one piece of lower bearing on the main shaft, the bearing of original installation has been saved to integral structure, and the structure is simpler, assembles more swift, and job stabilization nature is higher.

Description

Double-integral-bearing driving cam structure

Technical Field

The utility model relates to a, in particular to two solid bearing drive cam structures.

Background

A driving cam is used on the existing textile machinery computerized embroidery machine, a bearing is sleeved on a main shaft, and then a connecting rod and a flange are sleeved on the bearing. This structure is owing to need install the bearing additional, in the time of the assembly, has increased the supply and demand, has reduced efficiency, in the time of the use, poor stability.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that to prior art not enough, provide a two solid bearing drive cam structure.

In order to achieve the above object, the present invention takes the following measures:

a double-integral-bearing driving cam structure comprises a bearing large connecting rod, a flange bearing outer ring and a main shaft, wherein an upper bearing double-integral-cam connecting rod inner ring and a lower bearing double-integral-flange inner ring are integrally formed on the main shaft;

a plurality of balls are arranged between the large bearing connecting rod and the inner ring of the upper bearing double-integral cam connecting rod and between the outer ring of the flange bearing and the inner ring of the lower bearing double-integral flange;

and rolling grooves for rolling balls are formed in the inner side surface of the large bearing connecting rod, the outer side surface of the inner ring of the upper bearing double-integral cam connecting rod, the inner side surface of the outer ring of the flange bearing and the outer side surface of the lower bearing double-integral flange inner ring along the circumferential direction.

The utility model has the advantages that: the utility model has the advantages of the practicality, low in production cost, novel structure, the setting of two whole cam connecting rod inner circles of upper bearing and the two whole flange inner circles integrated into one piece of lower bearing on the main shaft, the bearing of original installation has been saved to integral structure, and the structure is simpler, assembles more swift, and job stabilization nature is higher.

Detailed Description

A double-integral-bearing driving cam structure comprises a bearing large connecting rod 1, a flange bearing outer ring 2 and a main shaft 3, wherein an upper bearing double-integral-cam connecting rod inner ring 3-1 and a lower bearing double-integral-flange inner ring 3-2 are integrally formed on the main shaft 3, the bearing large connecting rod 1 is sleeved outside the upper bearing double-integral-cam connecting rod inner ring 3-1, and the flange bearing outer ring 2 is sleeved outside the lower bearing double-integral-flange inner ring 3-2.

And a plurality of balls are arranged between the bearing large connecting rod 1 and the inner ring 3-1 of the upper bearing double-integral cam connecting rod, and between the flange bearing outer ring 2 and the lower bearing double-integral flange inner ring 3-2.

And rolling grooves 4 for rolling balls are formed in the inner side surface of the large bearing connecting rod 1, the outer side surface of the upper bearing double-integral cam connecting rod inner ring 3-1, the inner side surface of the flange bearing outer ring 2 and the outer side surface of the lower bearing double-integral flange inner ring 3-2 along the circumferential direction.

The technical scheme of the utility model, through the two whole cam link inner circles of bearing 3-1 and the two whole flange inner circles of lower bearing 3-2 on the main shaft 3 integrated into one piece's setting, the structure of ball and rolling groove 4 of deuterogamying has played the effect of bearing equally, has saved the assembly of original bearing arrangement under the condition that has the same function, has improved efficiency, simultaneously, because the part reduces, has also increased the stability of mechanism work.
