The utility model discloses the further improvement scheme is, the constant head tank on the cell wall in bar groove is equipped with two respectively along outside-in's direction.

The utility model discloses further improve the scheme and be, the distance between the notch in bar groove and the constant head tank that is close to ring body lateral wall one side equals the distance between two adjacent constant head tanks that the same side slot in bar groove was closed, also equals the distance between the constant head tank that the bar groove is close to ring body axle center department one side and the cell wall bottom in bar groove.

The utility model discloses a further improvement scheme is, the convex surface and the concave surface of cutting are the arc surface of mutual matching.

The utility model discloses further improve the scheme and be, the convex surface of cutting is towards the concave arc surface of the tank bottom in bar groove to when the location arch of cutting is just in time connected with the constant head tank cooperation that the bar inslot is close to ring body centre of a circle department, the convex surface of cutting and the concave arc surface of the tank bottom in bar groove laminate each other.

The beneficial effects of the utility model reside in that:

first, the utility model discloses a wide dynamic balance ring of control range according to the dynamic balance state of the pivot that records, through inserting the suitable position of bar inslot according to suitable angle with the poor strip of tai to realize the dynamic balance ring to the dynamic balance's of pivot regulation.

Second, the utility model discloses a wide dynamic balance ring of control range, the constant head tank in protruding, the bar groove of location through the cutting lateral wall to and the concave surface of cutting one end and the convex surface of one end make dynamic balance ring can have great control range, have improved dynamic balance ring's suitability.

Third, the utility model discloses a wide dynamic balance ring of control range, through the setting of a plurality of installation through-holes, the dynamic balance ring of being convenient for and the installation of pivot.

Description of the drawings:

fig. 1 is a schematic view of the present invention in partial section from the front view.

The specific implementation mode is as follows:

as shown in fig. 1, the utility model relates to a wide dynamic balance ring of control range, including ring body 1, the lateral wall of ring body 1 is equipped with a plurality of bar grooves 2 along the axis, bar groove 2 evenly distributed is in ring body 1's lateral wall, be equipped with cutting 3 in the bar groove 2, the both sides wall center of cutting 3 is equipped with the location arch, the cell wall of bar groove 2, correspond to the location arch and be equipped with the constant head tank 4 that matches, one end of cutting 3 is convex surface 5, the other end is concave surface 6, the tank bottom of bar groove 2 is the concave arc surface 7 that matches with the convex surface 6 of cutting 3, be equipped with the mounting through-hole 8 that runs through ring body 1 on ring body 1's lateral wall, be located between two adjacent bar grooves 2; two positioning grooves 4 are respectively arranged on the groove wall of the strip-shaped groove 2 along the direction from outside to inside; the distance between the notch of the strip-shaped groove 2 and the positioning groove 4 close to one side of the outer side wall of the circular ring body 1 is equal to the distance between two adjacent positioning grooves 4 on the same side of the groove closure of the strip-shaped groove 2 and also equal to the distance between the positioning groove 4 on one side of the strip-shaped groove 2 close to the axis of the circular ring body 1 and the bottom of the groove wall of the strip-shaped groove 2; the convex surface 5 and the concave surface 6 of the cutting 3 are arc surfaces matched with each other; when the convex surface 5 of cutting 3 is towards the concave cambered surface 7 of the tank bottom of bar groove 2 to the protruding constant head tank 4 cooperation that is close to the 1 centre of a circle department of ring body in 2 with bar groove of the location of cutting 3 is connected in time, the convex surface 5 of cutting 3 laminates with the concave cambered surface 7 of the tank bottom of bar groove 2 each other.
