Specific embodiment
The utility model provides a kind of rudder blade nut installation tool, makees referring to the drawings to the utility model detailed
Description, but following the description is not limited to the utility model.
As shown in Fig. 2, lower supporting plate (9) are installed with bolt (B4) first in the gusset of rudder blade nut peep hole, under
A through-hole is equipped with inside support plate (9), interior screw (B6) installs nut (14), and screw rod is arranged in nut (14)
(13), the thread forms of screw rod are consistent with the screw thread of rudder stock or rudder pintle, and the pivot flange (15) of screw rod (13) is in nut (14)
Top, four sides of lower supporting plate (9) are all provided with adjusting support (8) with bolt (B5), and inside adjusting support (8)
It is arranged adjusting rod (7), can adjust the center of lower supporting plate (9) by mobile adjusting rod (7).
As shown in attached drawing 6, attached drawing 6b, also set up shaft (16) on the pivot flange (15), and bracing ring (12)
Upper panel is equipped with the through-hole of installation shaft (16), so that bracing ring (12) is covered, in pivot flange (15), shaft (16) is also provided with afterwards
Inside the upper panel of bracing ring (12).End plate (1) is provided at this time and uses bolt (B1) fixed rotating shaft (16) and bracing ring (12),
So that bracing ring (12) is rotated together with screw rod (13)；The structure of the end plate (1) is as shown in attached drawing 4, attached drawing 4a, the support
The structure of (12) is enclosed as shown in attached drawing 5, attached drawing 5a.And bracing ring (12) has been welded as a whole in advance with upper backup pad (10), makes
Upper backup pad (10) is fixed on bracing ring (12) periphery, then installs plain thrust bearing (A) and pallet (5), and in pallet
(5) rudder blade nut is placed on.
Upper plain thrust bearing (A) further includes steel ball seat (2), steel ball (B3), cage ring (3), spacing collar (4)；Steel
The bottom and top of pearl seat (2) are fixed on upper backup pad (10) and pallet (5) with screw (B2)；Steel ball (B3) is arranged in steel
Pearl seat (2) is internal, and it is fixed by cage ring (3)；Spacing collar (4) is arranged in the outside of steel ball seat (2), and one end passes through
Screw (B2) is fixed on the pallet (5), and structure is as shown in Fig. 3.
The working principle of the utility model is as follows:
When rudder blade nut is installed on rudder stock as shown in Fig. 1, rudder blade nut is mounted on pallet (5), adjusts lower
The adjusting support (8) and adjusting rod (7) of fagging (9), adjustment rudder blade nut center and rudder stock or rudder pintle center, make rudder blade nut
Internal screw thread center and the externally threaded center of rudder stock or rudder pintle keep with one heart, adjusting center rami posterior inferior fagging (9) and being fixed on rudder blade sight
It examines on the gusset in hole.By spanner (11) rotary screw (13), lower supporting plate (9) is fixed at this time, so in rotary screw
(13) increase rudder blade nut, the upper branch that the shaft (16) of pivot flange (15) drives bracing ring (12) and welds together with it
Fagging (10) and pallet (5) increase together, and the rudder blade nut on pallet (5) also raises simultaneously.
After the internal screw thread and rudder stock of rudder blade nut or the external screw thread head tooth of rudder pintle are overlapped, by rotating upper backup pad (10)
On handle (6), so that rudder blade nut is screwed on rudder stock or rudder pintle.Due to being plane axis between pivot flange (15) and bracing ring (12)
It holds, so the power of rotation is smaller, when rudder blade nut constantly rises, screw rod (13) also constantly follow-up makes the branch of screw rod (13)
Staying orchid (15) supports the bracing ring on upper backup pad always.
By this tooling, rudder blade nut can be installed into rudder head or rudder pintle.
It is discussed in detail although the content of the utility model has passed through above preferred embodiment, but it should be appreciated that on
The description stated is not considered as limitations of the present invention.After those skilled in the art have read above content, for
A variety of modifications and substitutions of the utility model all will be apparent.Therefore, the protection scope of the utility model should be by appended
