Further, the bolt hole length of described shaft extension is not less than 5cm, mainly in order to ensure axial pressure intensity.
Further, described bolt hole is the bolt hole of same specification, is conducive to when dismantling like this, directly utilizes bolt during installation as instrument.
Further, described boss number of bolt hole is no less than 3.
Further, described bolt is also accompanied with compression spring, strengthens the axial pressure of gland.
Further, described bolt is made up of manganese steel, and manganese steel has the advantages such as intensity is high, wear-resisting, heat-resisting, corrosion-resistant, when can ensure that equipment transmits high power kinetic energy, not fragile.
Described gland has two kinds of functions in the utility model, and the first is in use, with coordinating of bolt group, rotating component and shaft extension is fitted tightly, realize transmission of power by gland; The second is when dismantling, and by gland reversion one side, by the cooperation of bolt group, only needs easily easily be separated with shaft extension by rotating component once secondary spanner.
A kind of rotating component actuating unit that the utility model provides not only can transmit high-power power, and install, convenient disassembly, do not need to install by professional equipment or alternate manner, dismounting, as long as can deal with problems once secondary spanner, reduce labor strength, enhance productivity.Moreover, the utility model equipment in installation, unloading process is not easy to wear, damage, extends the working life of equipment, reduces the equipment cost of enterprise.

Embodiment
In order to better set forth the utility model, elaborate below in conjunction with accompanying drawing.
As shown in figures 1 to 6, a kind of rotating component actuating unit, comprises rotating component 1, axis hole 10, shaft extension 4, its central axis hole 10 is arranged on rotating component 1 central authorities, and shaft extension 4 is power source main-axis end part, as motor shaft end, transmission group axle head etc., be arranged on axis hole 10, described axis hole 10 is the axis hole of frustum structure, and axis hole 10 outer surface diameter is less than internal surface 11 diameter, namely the plane that frustum is little is outer surface 11, large one side is internal surface, and shaft extension 4 has tapering, and shaft extension 4 coordinates with axis hole 10 installs.Shaft extension 4 is fit into from axis hole internal surface.
Rotating component actuating unit also comprises gland 2, gland 2 comprises cylindrical base 21 and cylindrical boss 22 two-part, their shaft axis is overlapping, outer surface 24 diameter of boss is less than or equal to outer surface 11 diameter of axis hole, and namely boss 22 can enter axis hole inside from the axis hole of outer surface 11 side of axis hole 10.Internal surface 25 diameter of base is greater than outer surface 11 diameter of axis hole, and namely base 21 can not enter axis hole inside from the axis hole of outer surface 11 side of axis hole 10.Concrete, base 21 and boss 22 are integrated, and base thickness is not less than 2cm.
Described boss 22 is provided with bolt hole 23, base 21 is provided with bolt hole 20, shaft extension 4 is provided with bolt hole 41, rotating component 1 is provided with bolt hole 12, the bolt hole 41 shaft axis overlap that bolt hole 23 on boss is corresponding with in shaft extension, the bolt hole 12 shaft axis overlap that the bolt hole 20 on base is corresponding with on rotating component; Described rotating component actuating unit also comprises bolt 3, and bolt 3 screws in bolt hole 41 corresponding in shaft extension, together with base inner surface 25 being fitted tightly with rotating component 1 through boss bolt hole 23.Make gland 2 have enough axial pressures, powerful transmission can be met like this.
Concrete, the bolt hole length of described shaft extension is not less than 5cm, mainly in order to ensure axial pressure intensity.The longer axial pressure intensity that it provides of length can be larger.Bolt hole is the bolt hole of same specification, is conducive to when dismantling like this, directly utilizes bolt during installation as instrument.
Concrete, boss number of bolt hole is no less than 3.Here boss number of bolt hole is 3, and is equilateral triangle by the triangle of their bolt hole 23 center of circle interconnecting line.According to mechanics, this structure is relatively stable, is conducive to equipment operation.
Concrete, described bolt 3 is also accompanied with compression spring, strengthens the axial pressure of gland.Bolt is made up of manganese steel, and manganese steel has the advantages such as intensity is high, wear-resisting, heat-resisting, corrosion-resistant, when can ensure that equipment transmits high power kinetic energy, not fragile.These designs are mainly all the axial pressures strengthening gland, provide safeguard for device can meet high-power transmission of power.
Concrete, when mounted, together with the base inner surface 25 of gland 2 fits tightly with rotating component 1, boss 22 side of gland 2 outwardly.During dismounting, screwed out by the bolt 3 being originally tightly locked in shaft extension bolt hole 41, then reversed by gland 2 with spanner, the outer surface 11 that axis hole 10 aimed at by boss 22 enters the end face that shaft extension 4 is withstood in axis hole inside.The bolt 3 screwed out is passed the bolt hole 20 of base, screw in the bolt hole 12 on rotating component 1, order tights a bolt 3 repeatedly, departs from until rotating component 1 loosens with shaft extension 4.Unload bolt and gland 2, just can realize the dismounting of rotating component 1 and shaft extension 4.
Compared with prior art, the utility model can realize high-power transmission of power, by professional equipment, can not need be removed and installed by a secondary spanner, very convenient, has significant progressive.
Above-mentioned embodiment can not be thought further restriction of the present utility model, and the unsubstantiality change that those skilled in the art make according to the utility model content all should fall in the utility model protection domain.
