Abstract
The utility model discloses a kind of marine gear box body, it includes upper gear box, the lower tooth roller box being rotatablely connected with the upper gear box and the seal assembly being arranged between the upper gear box and the lower tooth roller box, the lower gear case includes body part, with the pipe of coming about of upper gear box rotation connection, connect the connecting plate of the body part Yu the pipe of coming about, the body part is detachably connected with the connecting plate by bolt, the pipe of coming about is detachably connected with the connecting plate by bolt, since lower tooth roller box is divided into the body part being detachably connected by connecting plate and pipe of coming about by the utility model, when needing replacing sealing element, it only needs to remove connecting plate and body part is i.e. replaceable, to more simple and convenient, improve the replacement efficiency of sealing element.
Description
Technical field
The utility model relates to field of ship equipment, especially a kind of marine gear box body.
Background technique
Marine gearbox needs to rotate when coming about between upper and lower gear case body, and usually upper and lower gear-box case
The turned position of body is located under water, therefore the sealing of the part is particularly important.Sealing of coming about is generally rubber material, belongs to rapid wear
Part.When need replacing come about seal when, need first to remove upper gear box, could replace sealing of coming about, replacement is more not
Just.
Therefore, need one kind being capable of the quick and convenient gear case body for replacing sealing element of coming about at present.
Summary of the invention
The purpose of the utility model is to provide one kind being capable of the quick and convenient gear case body for replacing sealing element of coming about.
In order to achieve the above objectives, the technical solution adopted in the utility model is:
A kind of marine gear box body comprising upper gear box, with the upper gear box rotation connection lower tooth roller box and
Seal assembly between the upper gear box and the lower tooth roller box is set, the lower gear case include body part, with it is described
The connecting plate of the pipe of coming about of upper gear box rotation connection, the connection body part and the pipe of coming about, the body part with it is described
Connecting plate is detachably connected by bolt, and the pipe of coming about is detachably connected with the connecting plate by bolt.
Preferably, the upper surface of the connecting plate is connected with the lower end surface of the pipe of coming about, the following table of the connecting plate
Face is connected with the upper surface of the body part.
It is further preferred that on the connecting plate for connect the spiro keyhole position of the pipe of coming about in the connecting plate with
On the joint face of the body part.
It is further preferred that the connecting plate is connect with the pipe of coming about using hexagon socket head cap screw.
It is further preferred that the connecting plate is connect with the body part using studs.
Preferably, the seal assembly includes the internal sealed ring being fixedly connected with the outer wall of the pipe of coming about and the upper tooth
Multiple sealings of coming about of the outer seal ring that roller box is fixedly connected and the inner wall for being fixed at the outer seal ring.
It is further preferred that described come about is sealed into rubber and comes about sealing.
Preferably, described come about is provided with rolling bearing between pipe and the upper gear box.
Since above-mentioned technical proposal is used, the utility model has the advantage that compared with prior art
Since lower tooth roller box is divided into the body part being detachably connected by connecting plate and pipe of coming about by the utility model, when
When needing replacing sealing element, it is only necessary to it removes connecting plate and body part is i.e. replaceable, thus it is more simple and convenient, improve sealing
The replacement efficiency of part.
Detailed description of the invention
Attached drawing 1 is the structural schematic diagram of the utility model.
In the figures above: 1, upper gear box；21, body part；22, it comes about pipe；23, connecting plate；3, rolling bearing；41, interior
Seal ring；42, outer seal ring；43, it comes about sealing.
Specific embodiment
Embodiment shown in reference to the accompanying drawing is further described the utility model:
Referring to figure 1, a kind of marine gear box body comprising upper gear box 1 is rotatablely connected with upper gear box 1
Lower tooth roller box and the seal assembly that is arranged between upper gear box 1 and lower tooth roller box, lower gear case include body part 21, with it is upper
The connecting plate 23 of pipe 22 of coming about, connection body part 21 and pipe 22 of coming about that gear-box 1 is rotatablely connected, body part 21 and connecting plate 23
Be detachably connected by bolt, pipe 22 of coming about is detachably connected with connecting plate 23 by bolt, come about pipe 22 and upper gear box 1 it
Between be provided with rolling bearing 3.
The upper surface of connecting plate 23 is connected with the lower end surface for pipe 22 of coming about, lower surface and the body part 21 of connecting plate 23
Upper surface is connected.The spiro keyhole position for connecting pipe 22 of coming about on connecting plate 23 is in the connection of connecting plate 23 and body part 21
On face.Connecting plate 23 uses hexagon socket head cap screw to connect with pipe 22 of coming about, and connecting plate 23 is connect with body part 21 using studs.
Including hexagon socket head cap screw is protected, it is not easy to be corroded.
Seal assembly includes the internal sealed ring 41 being fixedly connected with the outer wall for pipe 22 of coming about, is fixedly connected with upper gear box 1
Multiple sealings 43 of coming about of outer seal ring 42 and the inner wall for being fixed at outer seal ring 42, sealing 43 of coming about are rubber seal.
Since lower tooth roller box is divided into the body part being detachably connected by connecting plate 23 21 and pipe of coming about by the present embodiment
22, when needing replacing sealing element, it is only necessary to it removes connecting plate 23 and body part 21 is i.e. replaceable, thus it is more simple and convenient,
Improve the replacement efficiency of sealing element.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention.
All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover the protection scope of the utility model it
It is interior.
