The utility model provides an installation device that is used for axle head round nut of roots blower rotation axis, simple structure under the not easy -operating situation in the radial region of round nut, can accomplish the installation of round nut easily, and the round nut that the extremely strong and fine protection of practicality was installed is not beated to damage influences its result of use.
Description
Technical field
This utility model relates to aerator and installs equipment, particularly rotates for Roots blower
The erecting device of the axle head round nut of axle.
Background technology
Revolution class frame for movement this for Roots blower, its rotational structure is essentially all to be adopted
Rotate excessively as intermediary with bearing, and fixing being essentially all that bearing is on the rotary shaft makes
Tighten fixing with round nut.Actually shop worker is when installing round nut, is all rough
Directly using club class and directly beat the groove of round nut, the result so produced is round nut
Directly be destroyed, there is potential safety hazard in the fixed effect of round nut, round nut disassembles again
Time directly scrap, cause because percussion power is excessive damage thread；Some in particular cases installs axle head
During round nut, because round nut radially operating region is the least, or round nut radial zone and other
Object is interfered, and the most just installs round nut without space.
Utility model content
Technical problem to be solved in the utility model is to provide for Roots blower rotary shaft
The erecting device of axle head round nut, simple in construction, processing and manufacturing is convenient, operability is very strong,
Under situation the most easy-operating for round nut radial zone, the installation of round nut can be readily accomplished,
The round nut that the extremely strong and good protection of practicality is mounted is not affected it by percussion damage and is used
Effect.
For realizing above-mentioned technique effect, this utility model provides for Roots blower rotary shaft
The erecting device of axle head round nut, it includes torque spanner, sleeve, projection and large end face bolt,
Sleeve is the cylinder being provided with an end face, and the end face centre of sleeve offers square groove,
One end of torque spanner is provided with square abaculus, and square abaculus is sleeved on the square recessed of sleeve end face
In groove, being provided with T-shaped groove inside the stack shell of described sleeve, projection is inlaid in T-shaped groove
In, the axial end of projection is provided with screwed hole, and large end face bolt stretches into the spiral shell of projection axial end
In pit hole, the end face of large end face bolt is close to the end face of sleeve.During use, by round nut set
Being contained in sleeve, set the torque value of torque spanner, rotary torsion spanner can complete circle spiral shell
Female installation.
This utility model improves further, and described projection entirety is T-shaped.
This utility model improves further, and sleeve and projection are designed with chamfering.
The peace of the axle head round nut for Roots blower rotary shaft that this utility model is proposed
Assembling device, simple in construction, processing and manufacturing are convenient, operability is very strong, for round nut radially
Under the most easy-operating situation in region, can be readily accomplished the installation of round nut, practicality is extremely strong and very
The round nut that good protection is mounted is not affected its using effect by tapping damage.

Detonation configuration schematic diagram.
The planar structure schematic diagram that when Fig. 2 is to install, round nut coordinates with erecting device.
Fig. 3 be in Fig. 2 A-A to structural representation.
Detailed description of the invention
See accompanying drawing, for the erecting device of the axle head round nut of Roots blower rotary shaft, it
Including torque spanner 1, sleeve 2, projection 3 and large end face bolt 4, sleeve is for being provided with one
The cylinder of end face, the end face centre of sleeve offers square groove, one end of torque spanner
Being provided with square abaculus, square abaculus is sleeved in the square groove of sleeve end face, described set
Being provided with T-shaped groove inside the stack shell of cylinder, projection is inlaid in T-shaped groove, projection axial
End face is provided with screwed hole, and large end face bolt stretches in the screwed hole hole of projection axial end, holds greatly
The end face of face bolt is close to the end face of sleeve.During use, round nut 5 is sleeved in sleeve,
Setting the torque value of torque spanner, rotary torsion spanner can complete the installation of round nut.
This utility model improves further, and described projection entirety is T-shaped.
This utility model improves further, and sleeve and projection are designed with chamfering 6.
The peace of the axle head round nut for Roots blower rotary shaft that this utility model is proposed
Assembling device, simple in construction, processing and manufacturing are convenient, operability is very strong, for round nut radially
