Abstract
The utility model provides an aircraft undercarriage bearing bolt sleeve belongs to aviation equipment technical field. The sleeve is formed by connecting an upper cylinder and a lower cylinder through a connecting cavity; the utility model discloses an undercarriage bearing bolt that will treat the fastening or relax is installed in the sleeve bottom, and the sleeve other end is connected with spanner or file, has solved the problem of the operation difficulty that traditional spanner and fuselage distance closely caused, has saved workman's manual labor and operating time, improves work efficiency, has certain guide meaning in the actual assembling process of undercarriage.
Description
Technical Field
The utility model belongs to the technical field of the aviation is equipped, concretely relates to be applied to bolt sleeve of undercarriage bearing.
Background
When operating personnel used tools such as open-ended wrenches or box wrenches to tighten the bolts in the current aircraft landing gear disassembling and assembling process, the wrenches are attached to aircraft parts closely, the acting force is hard to apply, and the operation process is time-consuming and labor-consuming and low in efficiency. And adopt a bolt sleeve and the mode that the spanner combination was used, can enlarge spanner and fuselage interval, the workman manually operation of being convenient for reduces the amount of labour, improves operating efficiency. However, at present, there is no special sleeve between the bolt and the wrench of the landing gear bearing, and therefore, it is very necessary to design a sleeve to solve the problem of torque transmission in connection between the bolt and the wrench.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides an aircraft landing gear bearing bolt sleeve.
The technical scheme of the utility model as follows:
a bolt sleeve for a bearing of an aircraft landing gear is formed by connecting an upper cylinder and a lower cylinder through a connecting cavity 4. Wherein, the top of the upper cylinder is provided with a wrench jack 1 for fixing a bidirectional ratchet wrench; the side surface of the upper cylinder is provided with a round hole 2 for fixing a file. The bottom of the lower cylinder is provided with a bolt jack 3 matched with a bolt.
Further, the axial leads of the wrench insertion hole 1 and the bolt insertion hole 3 are consistent with the axial lead of the connecting cavity 4.
Furthermore, the round holes 2 are provided with six positions which are uniformly distributed along the circumference of the upper cylinder at equal intervals.
Furthermore, the connecting cavity 4 is in a circular truncated cone shape, the upper part and the lower part of the connecting cavity 4 are in inclined transition, and the connecting cavity is formed in one step.
The utility model has the advantages that:
(1) the utility model provides an aircraft undercarriage bearing bolt sleeve through treating the undercarriage bearing bolt fastening or relaxing and fixing in the sleeve bottom, the other end is connected with spanner or file, has solved the problem of the operation difficulty that traditional spanner and fuselage distance lead to near excessively, has saved workman's manual labor and operating time, improves work efficiency, has certain guide meaning in the actual assembling process of undercarriage.
(2) The utility model provides an among the aircraft undercarriage bearing bolt sleeve, use ratchet spanner or ordinary file all can be independent work of going on, not only depend on ratchet spanner, use convenient and fast more.

Detailed Description
In order to make the objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. It should be apparent that the described embodiments are only exemplary of some, but not all, embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art without inventive labour based on the embodiments of the invention, such as for example only changes in use without changing the claims as to the embodiments relating to the basic principles, are within the scope of protection of the invention.
In the description of the present invention, it should be understood that the terms "upper", "lower", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, which are merely for convenience of description and simplification of description, and do not indicate or imply that the indicated position or member must have a specific orientation, be constituted in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
As shown in fig. 1, an aircraft landing gear bearing bolt sleeve is a shell structure formed by connecting an upper cylinder and a lower cylinder through a connecting cavity 4. Wherein, the top of the upper cylinder is provided with a wrench jack 1 for fixing a bidirectional ratchet wrench; the side surface of the upper cylinder is provided with a round hole 2 for fixing a common file. The bottom of the lower cylinder is provided with a bolt jack 3 matched with a bolt for installing the bolt.
The wrench jack 1 and the bolt jack 3 are aligned with the axis of the connecting cavity 4. The connecting cavity 4 is in a circular truncated cone shape, the upper part and the lower part of the connecting cavity 4 are in inclined transition, and the connecting cavity is manufactured in a one-step forming mode. The circular holes 2 are provided with six positions and are evenly distributed along the circumference of the upper cylinder at equal intervals.
During the use, will wait to fasten or the undercarriage bearing bolt that relaxs installs in the bolt jack 3 of sleeve bottom, and the sleeve other end is connected with spanner or file, realizes the installation and the dismantlement of aircraft undercarriage bearing bolt through rotating the sleeve.
