Technical field
This utility model relates to gear mechanism, particularly to a kind of Novel spiral bevel gear mechanism.
Background technology
In the power transmission process of helical gear, between helical gear and quadrature axis, there is frictional force, so that quadrature axis is at spiral
Rotating more smooth on gear, fluted between each helical tooth, the ground indent of groove defines oil groove to cache lubricating oil,
But the problem arranging existence of this structure is: during life-time service, lubricating oil can deposit in groove forms oil clot,
Oil clot occupies the space of groove, and being subsequently implanted into groove oil mass can be fewer and feweri, needs again oiling, cause profit after using the short time
The waste of lubricating oil.
It addition, gear mechanism is widely used in various drive system, it is by gear shaft and the umbrella being fixed on gear shaft
Gear is constituted, and for general cylindrical gear shaft, a maximum feature of gear shaft can directly change transmission side exactly
To, it is mainly used in the motion that two axles intersect, is suitable in high speed level legacy system.Traditional bevel gear is typically at one section
Being spaced multistage axle on multidiameter to install, this structure space being primarily due to machine is limited, it has to design the longest
A rooted tooth wheel shaft adapt to transmission needs, and may relate to need on an axle to process multiple in some drive system
The situation of bevel gear, then shaft design is the most increasingly complex, size is bigger, processes more difficult；It is known that gear shaft
Machining accuracy plays very important effect to transmission accuracy and the efficiency of drive system, structure gear complicated, larger-size
Axle difficulty of processing is big, and aborning probably because certain section of axle processing error causes whole axle thoroughly to be scrapped, economy is poor.
Utility model content

Face indent forms the oil groove of caching lubricating oil, and described oil groove is trapezoidal-structure, and the one side of oil groove is cleaning face, clean face with
The equal arc transition in the bottom surface of oil groove and the bottom surface of groove, is additionally provided with cleaning structure in described oil groove；
Described gear shaft include diameter different first installation axle, second install axle, the 3rd install axle, described two install axle positions
Installing axle and the 3rd in first and install between axle, it is convex that described second one end installing axle and the first installation axle connection is provided with taper
Platform, described second installs the graduation mark being machined with depression on axle, and described first installs axle has away from second one end installing axle
Cannelure；Described 3rd installation axle is pyramidal structure.
Wherein, described cleaning structure includes two sliding seats, is respectively arranged with two on the two sides that oil groove is adjacent with cleaning face
Individual chute, each chute is all parallel with the face of cleaning, and two sliding seats are slideably positioned in two chutes respectively, two slips
Connect between Zuo and have cleaning brush.
Further, the outer surface of described helical tooth is provided with carburized layer, and the thickness of carburized layer is 1.8～2.2mm.
Compared to prior art, this utility model has the advantages that
1) it is trapezoidal-structure by arranging oil groove, owing to the bottom of trapezoidal-structure is relatively deep, has certain volume, therefore
Ensure that oil groove can accommodate the lubricating oil of certain volume, be simultaneously set to the shape that trapezoidal-structure is cleaning face
One-tenth is laid a good foundation；It is connected by arranging cleaning face arc transition equal with the bottom surface of the bottom surface of oil groove and groove,
The obstruction being subject to during oil clot on the bottom surface removing oil groove reduces, and establishes for the removing of oil clot on the bottom surface of oil groove
Determine basis；By arranging cleaning structure, facilitate and maintenance process is removed the oil clot in oil groove, due to
Whole cleaning structure is positioned at oil groove, and therefore cleaning structure will not hinder the transmission of helical gear to work；
2) first axle is installed, second axle is installed, the 3rd three parts of axle are installed are designed as one, simple in construction, easily
In processing, there is preferable economy, and second install that the graduation mark on axle formed rough
Axial plane can be used for riveting other actuated element such as gear or belt wheel, reaches to increase the purpose of drive line,
Realize multidirectional transmission, make drive system structure the compactest.

Fig. 1 is assembling structural representation of the present utility model；
Fig. 2 is the structural representation of bevel gear in this utility model；
Fig. 3 is the partial enlargement structural representation of aminoacyl site in Fig. 2.
Detailed description of the invention
Below in conjunction with the accompanying drawings and the technical scheme in this utility model is further illustrated by embodiment.
As shown in Figure 2 and Figure 3, the utility model proposes a kind of Novel spiral bevel gear mechanism, including bevel gear 1 and with
The gear shaft of its socket, described bevel gear 1 includes the wheel body that one end is the conical surface, and described wheel body has been evenly arranged multiple spiral
Tooth 2, has groove between adjacent helical tooth 2, and bottom surface 112 indent of groove forms the oil groove of caching lubricating oil, described
Oil groove is trapezoidal-structure, and the one side of oil groove is cleaning face 111, cleans face 111 and the bottom surface 112 of oil groove and the end of groove
The equal arc transition in face 112, is additionally provided with cleaning structure 3 in described oil groove, to be removed from cleaning face 111 by oil clot.Its
In, in order to design simple in construction, easy to use, the cleaning structure 3 of low cost of manufacture, it is preferred that cleaning structure 3 wraps
Include two sliding seats 31, the two sides that oil groove is adjacent with cleaning face 111 are respectively arranged with two chutes 32, each cunning
Groove 32 is all parallel with cleaning face 111, and two sliding seats 31 are slideably positioned in two chutes 32 respectively, two slips
Connect between seat 31 and have cleaning brush 33.So that it is laborsaving when cleaning oil clot.Preferably, sliding in each chute 32
Move and be respectively connected with spring between seat 31 and the end face of chute 32.
As it is shown in figure 1, shown gear shaft includes first installation axle the 4, second installation axle the 5, the 3rd installation axle 6 that diameter is different,
Described second installs axle 5 installs between axle 4 and the 3rd installation axle 6 first, and described second installs axle 5 and first installs axle 4
The one end connected is provided with cone boss 7, cone boss 7, it is simple to gear shaft axially positions, and described second installs processing on axle 5
Having a graduation mark of depression, described first installs axle 4 has cannelure 8 away from second one end installing axle 5, cannelure 8 be easy to
The connection of other parts；Described 3rd installation axle 6 is pyramidal structure；Specifically, bevel gear 1 can be made of one formula knot with gear shaft
Structure, it is possible to use key connecting.Unlike conventional tooth wheel shaft, this utility model gear is arranged on the second installation axle 5,
It is respectively arranged at two ends with the first installation axle 4 and second in the left and right of gear and axle 5 is installed, peace can be selected when installing and using as required
Fill at two bearing or bearing at is only installed.In above-mentioned installation axle, the 3rd installs axle 6 is connected with the second installation axle 5, described
Second surface installing axle 5 is axially arranged with the graduation mark of the depression being evenly arranged, and it is rough that above-mentioned graduation mark is formed
Axle surface can be used for installing the actuated elements such as other bevel gear 1, roller gear or belt wheel, makes associated actuator element firmly
It is fixed on the second installation axle.In view of, the simplicity of this gear shaft structure, above-mentioned bevel gear 1 and each section of axle can be made of one
