Description

Detachable output flange structure, gearbox and engineering vehicle

Technical Field

The utility model relates to a can dismantle output flange structure belongs to gearbox technical field.

Background

The output flange is one of indispensable important parts on the gearbox in the engineering machinery industry, and the space of the joint is smaller after the output flange is installed on most of the gearboxes at present, and although the overall structure of the gearbox is greatly designed and improved, the obvious defect that the space of the joint is smaller cannot be obviously improved. If the gearbox is maintained or parts such as an output flange and the like are replaced, the problem of difficulty in disassembly is often existed, for example, the disassembly is inconvenient, the labor intensity is high, the disassembly efficiency is low, and the like. Especially under the condition that the installation space of the output flange of the existing gearbox is limited or smaller, the disassembly difficulty is more obvious. Not only cause the degree of difficulty increase, the work load grow of dismantlement and assembly, still bring very big inconvenience for the maintenance personal, inefficiency during the operation, waste time and energy, bring very big inconvenience for its whole maintenance and whole overall process of change.

Disclosure of Invention

The utility model aims at providing a can dismantle output flange structure especially is applicable to occasions such as dismantlement, the maintenance of output flange under the limited condition in space.

In order to achieve the above purpose, the utility model adopts the technical scheme that:

a detachable output flange structure comprises a bearing, a rotary oil seal, a dust cover I, a dust cover II, an output shaft and an output flange; the bearing is installed to gearbox box bearing hole department, the output shaft is installed to the bearing hole position, rotatory oil blanket is installed to gearbox output flange aperture department, output flange boss position on the gearbox is installed to dust cover I, output flange is installed to gearbox output flange aperture department, dust cover II is installed to output flange tang position.

Further, the output flange is connected with the output shaft through a spline.

Further, the dust cover II is welded at the spigot position of the output flange.

Further, the rotary oil seal is of a double-lip structure.

A gearbox is provided with the detachable output flange structure.

A work vehicle is provided with the gearbox.

The utility model discloses can dismantle output flange structure compares with current output flange structure, possesses characteristics such as simple structure, economical applicable, maneuverability is strong and safe and reliable. It adopts the rotatory oil blanket of two lips, possesses good oil sealing function to dispose two dust covers, play dual dirt-proof effect, under the comparatively abominable condition of gearbox operating mode, filths such as ability to a great extent avoid external mud, dust get into, cleanliness between output flange and the rotatory oil blanket has been guaranteed to existing effect, cleanliness between output flange and the output shaft has also been guaranteed simultaneously, the probability that greatly reduced gearbox broke down, the life of extension gearbox. The disassembly process is simple, other auxiliary tools are not needed, the disassembly can be directly carried out, the labor intensity is greatly reduced, the safety of the disassembly process is guaranteed, and the disassembly efficiency is improved. The structure is also suitable for field disassembly with poor working conditions, and the problem that the output flange is difficult to disassemble under the condition that the installation space of the output flange of the gearbox is limited or the installation space is small is solved.

Drawings

Fig. 1 is a schematic structural view of the present invention;

FIG. 2 is a partial enlarged view of the present invention;

the device comprises a bearing 1, a bearing 2, a gearbox 3, a rotary oil seal 4, a dust cover I, 5, a dust cover II, 6, an output shaft 7 and an output flange.

Detailed Description

In order to make the implementation objects, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be described in more detail below with reference to the accompanying drawings in the embodiments of the present invention. In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The described embodiments are only some, but not all embodiments of the invention. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in figure 1, the utility model relates to a can dismantle output flange structure includes bearing 1, rotatory oil blanket 3, dust cover I4, dust cover II 5, output shaft 6 and output flange 7.

The output flange 7 and the output shaft 6 in the structure of the utility model are connected by splines and can freely move in a certain range, and the interference of accessory parts such as hand brakes and the like to the installation space is avoided; the rotary oil seal 3 that adopts is two lip structures, and the oil seal effect is showing fairly to contain two dust covers, play dual dirt-proof function, this cleanliness in output flange 7 and rotary oil seal 3 and output flange 7 and output shaft 6 junction space has greatly been guaranteed.

The assembly process for a removable output flange configuration is substantially as follows: install bearing 1 to 2 box bearing hole departments of gearbox at first, assemble output shaft 6 to the bearing hole position again, secondly assemble rotatory oil blanket 3 to 2 output flange pore departments of gearbox, pack into I4 dust cover to the 2 output flange boss positions of gearbox on, assemble output flange 7 to 2 output flange pore departments of gearbox (through the spline hookup between output flange and the output shaft) again, assemble II 5 dust covers to output flange tang position through the welding at last again.

The utility model has the advantages of simple structure, economy is suitable for, dismantles process security reliable, the dismantlement under the less condition of specially adapted gearbox output flange installation space, and it dismantles the process simply, and maneuverability is strong, need not be with the help of other appurtenance such as hammer or spanner, alright direct dismantlement. The problem of output flange dismantle the difficulty under the less condition in gearbox space is solved, intensity of labour has been reduced simultaneously and the cost is dismantled, has promoted the maintenance efficiency of gearbox output flange. It adopts two lip oil blanket structures, and the oil seal effect is showing to dispose two dust covers, play dual dustproof effect, can effectively avoid the gearbox to get into at filths such as the external mud of abominable working process, dust, prolonged the life of gearbox.

The utility model also discloses a gearbox has aforementioned output flange structure of dismantling.

The utility model also discloses an engineering vehicle has aforementioned gearbox.

Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present invention and not to limit the same; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will understand that: modifications to the specific embodiments of the invention or equivalent substitutions for parts of the technical features may be made; without departing from the spirit of the present invention, it is intended to cover all aspects of the invention as defined by the appended claims.
