Abstract
The utility model provides a taper sleeve. The front end is an exterior conical surface. The cylinder on the back of the taper sleeve is uniformly provided with three thread through-holes and three unthreaded holes. The unthreaded holes are arranged inside the taper sleeve body, and are in clearance fit with a direct axis under the free state. A seam is arranged along the axial direction of the taper sleeve, which better solves the installation problem of the belt pulley and the shaft. The technical proposal saves labors and time, and the operation is reliable. In addition, the structure of the taper sleeve is simple and reasonable, which is convenient to be manufactured.
Description
Technical field:
The utility model relates to a kind of oil field operation instrument, is a kind of tapered sleeve that belt pulley is connected with d-axis that is used to dismantle specifically.
Background technique:
At present, known belt pulley is that interference fit directly is connected with the Placement of d-axis.Effort very all when using the belt pulley of this Placement on d-axis, to assemble or dismantle, and be easy to injury axle and belt pulley.
Summary of the invention:
The purpose of this utility model is to avoid the deficiencies in the prior art and provide a kind of belt pulley of easily detachable to be connected tapered sleeve with d-axis.
The purpose of this utility model is achieved in that tapered sleeve, front end is an outer conical surface, and equally distributed three tapped through holes and three unthreaded holes are arranged on the cylindrical body of tapered sleeve body back, and tapered sleeve body inside is unthreaded hole, it and d-axis are Spielpassung when free state, axially have a seam along tapered sleeve.
Compared with prior art, tapered sleeve is connected this technology refer to belt pulley and install up, solved the installation difficult problem of belt pulley well with axle.This technological scheme is time saving and energy saving, reliable operation.In addition, tapered sleeve simple and reasonable is convenient to manufacture.
Description of drawings:
Fig. 1 is a sectional view structural representation of the present utility model.
Fig. 2 is a left view of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is elaborated.
Tapered sleeve body front end is an outer conical surface 5, and equally distributed three tapped holes 1 and three unthreaded holes 2 are arranged on the cylindrical body of tapered sleeve body back, and tapered sleeve body inside is a unthreaded hole 3, with d-axis be Spielpassung when the free state.Axially have interspace seam 4 along tapered sleeve.
Be connected with use tapered sleeve in the middle of the d-axis at belt pulley, solved the problem that common interference fit directly is linked and packed or dismantles effort.
When assembling, the belt pulley internal conical surface matches with tapered sleeve outer conical surface 5.Three bolts pass unthreaded hole 2 and are connected with tapped hole on the belt pulley.By tightening this three bolts, belt pulley internal conical surface extruding tapered sleeve outer conical surface 5 causes outer conical surface 5 to shrink, and tapered sleeve opened gap seam 4 diminishes, and then causes the tapered sleeve internal diameter to diminish.Belt pulley and axle sleeve just have been fixed on axle upward tightly like this.When dismounting, these three bolts are backed out, and penetrated in the tapped hole 1 of tapered sleeve.Tighten this three bolts, the belt pulley internal conical surface separates with tapered sleeve outer conical surface 5, causes outer conical surface 5 to recover distortion, and tapered sleeve opened gap seam 4 recovers, and then causes the tapered sleeve internal diameter to recover.Belt pulley and axle sleeve have just been thrown off with axle like this.
Claims (1)
1, tapered sleeve, its structure characteristic is that front end is an outer conical surface, and equally distributed three tapped through holes and three unthreaded holes are arranged on the cylindrical body of tapered sleeve body back, and tapered sleeve body inside is unthreaded hole, it and d-axis are Spielpassung when free state, axially have a seam along tapered sleeve.
