Abstract
The utility model relates to an eccentric transmission gear for a graticule machine. The structure is that a draw bar is connected to the upper end of a straight arm; the lower end of the straight arm is connected with a bearing base; a bearing is connected with the middle part of the straight arm; the bearing is seated in an eccentric disc, and the eccentric disc is sleeved on a transmission shaft. The eccentric transmission gear for the graticule machine uses an oval eccentric disc to internally buckle the bearing on the straight arm, so that the straight arm can drive the draw bar to do reciprocating motion with large amplitude, and the eccentric transmission gear can meet the operating stroke required by a wire drawing shaft in reciprocating swing, therefore, the transmission mechanism for driving a weft wire drawing shaft to swing in a reciprocating manner is simplified. Furthermore, the transmission bearing on the straight arm carries out rotational motion in a slide way in the eccentric disc, is not separated due to the constraint of the eccentric disc, and is stable in transmission performance; the fault rate is reduced, and the work reliability is improved.
Description
Technical field
The utility model relates to a kind of eccentric drive mechanism, specifically a kind of Graticule machine radial gear.
Background technique
On the existing Graticule machine, drive the driving mechanism more complicated of parallel wire drawing axle reciprocally swinging, adjust to some extent inconvenience, it is longer that the shutdown maintenance after breaking down is adjusted the time, affected working efficiency.
The model utility content
The purpose of this utility model just provides a kind of Graticule machine radial gear, to simplify wire drawing shaft transmission, reduce trouble.
The utility model is achieved in that a kind of Graticule machine radial gear, termination pull bar on straight-arm, and abutting shaft holds base under the straight-arm, and straight-arm middle part spindle is held, and described bearing is seated in the eccentric disc, and described eccentric disc is socketed on the transmission shaft.
Described eccentric disc comprises oval-shaped disk body, is provided with the vertical edge perpendicular with disc surfaces in disc perimeter, is provided with oval-shaped boss at disk body middle part, one side at the axis hole that has perforation of described boss.
The utility model utilizes the drive bearing on the button straight-arm in the oval eccentric disc, can make straight-arm drive pull bar and form significantly to-and-fro motion form.Just can satisfy the required working stroke of wire drawing axle reciprocally swinging with this eccentric drive mechanism, thereby simplify the mechanical transmission mechanism that drives parallel wire drawing axle reciprocally swinging.And the rotation motion in the slideway of the drive bearing on the straight-arm in eccentric disc is subjected to the constraint of eccentric disc, can not break away from voluntarily, and transmission performance is stable, and rate of fault reduces, and functional reliability improves thereupon.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of eccentric disc.
Among the figure: 1, pull bar, 2, eccentric disc, 3, boss, 4, transmission shaft, 5, straight-arm, 6, bearing, 7, bearing base.
Embodiment
As shown in Figure 1, the utility model is the upper termination pull bar 1 at straight-arm 5, and the lower end of straight-arm 5 is hinged on the bearing base 7, and the middle part spindle of straight-arm 5 holds 6, and bearing 6 is seated in the eccentric disc 2, and eccentric disc 2 keys are connected on the transmission shaft 4.
As shown in Figure 2, eccentric disc 2 has an oval-shaped disk body, periphery at disk body is provided with the vertical edge perpendicular with disc surfaces, is provided with oval-shaped boss 3 at the disk body middle part, forms between the side edge of boss 3 and the vertical edge of disk body and drives the slideway that straight-arm drive bearing 6 rotates.Have the axis hole of perforation on one side of boss 3, in order to cross-under transmission shaft 4.
