Description
Technical field
This utility model belongs to wind power generating set fastener areas, particularly relates to a kind of check bolt group
Part.
Background technology
There is the vibration of upper frequency, impact and varying load situation in the working environment of wind-driven generator so that
One or more fasteners is difficult to play fastening effect, and the kind quantity of the sensor installed in wind-driven generator is more,
The securing members such as bolt can be made to loosen under for a long time vibration, cause sensor cannot normally detect rotating speed,
The signal such as temperature or pressure, makes unit fault rate too increase maintenance cost while raising.To this, wind
Such as anemoclinograph in power generator group, temperature sensor, the installation spiral shell of generator speed proximity switch etc.
Bolt all can add some locking measures.
The most conventional screw retention method has three kinds: rub locking, mechanical locking and the most locking.Rub
Erasing is locking to be utilized increases between screw thread or bolt and the frictional force in nut support face or increase both frictions simultaneously
Power reaches locking purpose.Rub locking not by use space limited, can the most repeatedly dismantle,
Can motor-driven assemble, it needs securing member is applied enough pretightning forces, and pretightning force is the most just difficult to reach to increase
The purpose of major thread frictional force, the simultaneously Proper Match of hardness to be considered, and the punching of unit frequent vibration
Hit, varying load all can affect the frictional force between securing member and cause securing member to loosen.During mechanical type is locking often
Slotted nut is had to join split pin, round nut band locked spacer, series connection steel wire bundle, these methods reliable
Property typically additionally depends on the intensity of mechanical fixed part, too increases the weight being fastenedly connected, manufactures and install
Inconvenience, and motor-driven installation can not be carried out.It is for the fastening effect of some large diameter bolts inconspicuous,
As in wind-driven generator, bolt is fixed in the installation of shaft coupling.Permanent anti-loose structure is owing to mostly wanting when dismounting
Destroy threaded fastener, so that it cannot reuse, so reality is seldom used spot welding, riveting
Or bonding method carry out fastening bolt.
It is therefore proposed that a kind of locking spiral shell being applicable under the vibration of upper frequency, impact and varying load operating mode
Bolt assembly just seems the most necessary.
