Be equipped with the expansion joint on the clamp ring, the expansion joint is used for adjusting the size of clamp ring self, and when clamp ring inwards pressed from both sides tightly, the expansion joint reduces, and the clamp ring inside wall can the even application of force, prevents that the application of force is uneven, and the skew takes place for the axle sleeve to press from both sides tight structure axle center.
In the shaft sleeve clamping structure, the clamping ring is provided with a first threaded hole and a second threaded hole, the first threaded hole and the second threaded hole respectively penetrate through two side walls of the expansion joint, and one end of each threaded hole is provided with a propping surface.
Screw hole one and screw hole two are seted up to the expansion joint both sides, and screw hole one can change the size of expansion joint through bolted connection with screw hole two, makes clamp ring inside press from both sides tightly, and the face of supporting that screw hole one end has is used for supporting to lean on the bolt, prevents that the bolt from destroying the periphery wall of clamp ring at the wrong income in-process, also avoids the bolt to collide impaired with its spare part after fixed, prevents to have the phenomenon that the bolt remainder in the screw hole can't take out.
Compared with the prior art, this axle sleeve presss from both sides tight structure has following advantage:
one end of the body clamping portion is provided with a plurality of deformation holes along the axial direction of the body, the deformation holes are connected to form a deformation portion which is matched with the clamping ring to clamp the deformation portion inwards, so that the body is fixed on the rotating shaft, force is uniformly applied in the clamping process, and the axis of the shaft sleeve clamping structure cannot deviate.
And one end of the body clamping part is provided with an annular blocking edge I, one end of the clamping ring is abutted against the annular blocking edge I, the inner peripheral wall clamps the deformation part, and the clamping ring is prevented from applying force to a part without the deformation hole to cause the breakage and the fracture of the outer wall of the clamping part in the inward clamping process.
And thirdly, the clamping ring is provided with a first threaded hole and a second threaded hole, an expansion joint is arranged between the first threaded hole and the second threaded hole, and the size of the expansion joint is adjusted by screwing a bolt into the first threaded hole and the second threaded hole, so that the clamping ring attaching and clamping part is clamped on the rotating shaft.
And fourthly, the annular blocking edge formed by inwards recessing one end of the clamping part thickens the thickness of the deformation part, and the deformation part is prevented from being broken or damaged in the clamping process.
And fifthly, the other end of the deformation part extends inwards and is sunken downwards to form a limiting groove, so that the rotating shaft is limited in the clamping process, and the axle center of the shaft sleeve clamping structure is prevented from deviating in the clamping process.
