Detailed description of the invention
In order to illustrate more clearly of technical solution provided by the present application, attached drawing will be briefly described below.It is aobvious and easy
Insight, drawings discussed below are only some embodiments of the present application.
Fig. 1 is spanner schematic diagram used in the prior art.
Fig. 2 is that schematic diagram is worn and tightened to nut in the prior art.
Fig. 3 is the steel wire drive spanner schematic diagram of the application.
Specific embodiment
To keep the purposes, technical schemes and advantages of the application implementation clearer, below in conjunction in the embodiment of the present application
Attached drawing, technical solutions in the embodiments of the present application is further described in more detail.
The purpose of the application is in the case that solution twisting angle is small, and nut single rotates 180 or more problem, to guarantee
Nut is reliably worn.Secondly, it is small to can solve twisting angle, nut, which is twisted, frequently lifts-the problem of matching spanner by needs.
Therefore, application provides the nut installation method in a kind of small-diameter deep disk chamber, mainly includes three phases: nut
In the wearing stage, nut, which is twisted, leans on stage and nut limiter stage.
The stage is worn in nut, nut wears stage needs satisfaction installation and single rotates 180 requirements above in order to meet.
The common spanner that rotation angle is greater than twisting angle has ratchet spanner and gear wrench, but the rotation angle of ratchet spanner passes through
It moves back and forth and realizes, one direction rotation angle equally cannot be guaranteed the reliable connection of screw thread, usual situation because being unable to reach 180
Under, ratchet spanner need to use after nut tightens 1 circle；Gear or toothed belt transmission spanner size are big, the structure between compressor disc
Under size limitation, installation is very poor, and structure is complicated, at high cost.
For this purpose, this application provides steel wire drive spanners, as shown in Figure 3.Steel wire drive spanner mainly by active line wheel 5,
Diameter 0.6mm wirerope 8 (2), driven line wheel 1, connecting rod 3, retaining ring 2, nut 4, shaft 6 and handle 7 form, connecting rod 3 with turn
Axis 6 is vertically arranged, and active line wheel 5 rotatably covers in shaft 6 and be arranged in one end of connecting rod 3, and driven line wheel 1 is rotatable
Be set to the other end of connecting rod 3, and driven line wheel 1 is parallel with 5 axis of active line wheel, wirerope 8 be connected to active line wheel 5 and from
Moving-wire wheel 1, for rotating driven line wheel 1 with active line wheel 5.Nut is mounted in the driven line wheel 1 with spanner driving head,
Operator can drive driven line wheel 1 and nut synchronous rotary by rotating active line wheel 5.It rotates angle and depends on wirerope 8
Length.Not in contact with the faying face and nothing but limiter due to the stage nut, therefore spanner size is of less demanding, it is only necessary to meet installation
?.
To avoid wirerope 8 from respect to line wheel frictional force being not enough to that line wheel is driven to move, guarantee that it can overcome bolt and nut
Between active force, drive nut rotation, the application realizes the driving of driven line wheel 1, abandoning tradition by the pulling force of wirerope 8
Frictional force action mode.If borrowing its pulling force, the both ends by wirerope 8 is needed to be separately fixed at active line wheel 5 and from moving-wire
On wheel 1；And to guarantee that wirerope 8 moves in line wheel steel wire trough always, certain tensile force should be made it have.Due to steel wire
The limitation for material and the spanner size of restricting, the modes such as welding, screw in compression are all unavailable, and the method that wirerope is reliably fixed has very much
Limit, the application borrow in advance tubule truncation mode by fixation with steel wire in tubule, change line wheel central moment realize steel wire tensioning.
Need to meet installation and installation effectiveness requirement in the nut stage of tightening.Since nut is reliably connected with bolt,
And it is not necessarily to limiter, therefore, which can be operated more simple using rotatable ratchet spanner at any angle after single installation
Just, more efficient.
Nut tightens nut in the stage and needs to contact faying face, therefore to need to design step convex to hide core for pinch bar
Finished parts may be selected in edge, driving end.
It needs to meet installation and limiter requirement in the nut limiter stage, continues to use the c-type spanner of original process, but specific structure
It can be more flexible.For example, disk inner wall away from distance between Bolt sizes are small or disk it is small when, spanner driving head can be designed as
Opening form, spanner is moved radially and is cooperated as nut, and installation is higher.
The steel wire drive spanner and the nut installation method in small-diameter deep disk chamber of the application comes compared with the prior art
It says, improves assembly efficiency, the assembly time of 48 nuts was reduced to 6h by 5 days of original process, secondly steel wire drive spanner
Structure design is simple, and installation is good.Suitable for narrow installation space, the steel wire drive spanner structure driven by pulling force.
The above, the only specific embodiment of the application, but the protection scope of the application is not limited thereto, it is any
Within the technical scope of the present application, any changes or substitutions that can be easily thought of by those familiar with the art, all answers
Cover within the scope of protection of this application.Therefore, the protection scope of the application should be with the scope of protection of the claims
It is quasi-.
