Description
Technical field
The utility model relates to retarder gear rings, more particularly to retarder gear ring.
Background technique
Retarder gear ring is important one of transmission mechanism, with transmitting power bracket is big, transmission efficiency is high, can be any
The characteristics of transmitting movement and the power between two axis.Currently, retarder gear ring in the market is mostly solid construction, required production
The problem of material is more, and it is big that there are weight, high production cost is badly in need of solving as a result, in addition, existing gear-driven efficiency is high.
Summary of the invention
The utility model is directed to the problems of the prior art, provides retarder gear ring.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals:
Retarder gear ring, including gear, gear include centre tooth wheel body and outer ring, the outer surface setting of outer ring
There are several gear teeth, the center of centre tooth wheel body is provided with axis hole, and central gear outside is connected with outer ring medial surface, centre tooth
Offer multiple through-holes on wheel body, the both ends of axis hole and through-hole offer chamfering, and upper end chamfer is 45 °, and lower end chamfer is equal
It is 30 °.
Preferably, outer ring and centre tooth wheel body junction are equipped with arc surface, the two is excessive by arc surface.
Preferably, the medial surface both ends of outer ring are equipped with chamfering, chamfering is 45 °.
Preferably, being provided with wearing layer in gear.
Preferably, the number of teeth is 56, pressure angle is 20 °, reference diameter 192.08mm, and helical angle is 29 °.
Preferably, the section of the tooth of outer ring is the isosceles trapezoid of two stackings, the tooth socket between tooth is arc-shaped.
The utility model has significant technical effect: the utility model retarder due to using above technical scheme
Gear ring structure is simple, it is easy to accomplish, life is greatly reduced under the premise of guaranteeing its integral strength by using such structure
Material is produced, saves production cost, in addition, improving by the parameters to gear, so that it is when in use, efficiency is more
Height, noise are smaller.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the cross-sectional view of the utility model.
The toponym that each number designation is referred in attached drawing is as follows: 1-centre tooth wheel body, 2-axis holes, 3-through-holes,
4-outer rings.
Specific embodiment
The utility model is described in further detail with embodiment with reference to the accompanying drawing.
Embodiment
Retarder gear ring, including gear, gear include centre tooth wheel body 1 and outer ring 4, the outer surface of outer ring 4
Several gear teeth are provided with, the center of centre tooth wheel body 1 is provided with axis hole 2,1 lateral surface of centre tooth wheel body and 4 medial surface phase of outer ring
Even, multiple through-holes 3 are offered on centre tooth wheel body 1, axis hole 2 and the both ends of through-hole 3 offer chamfering, and upper end chamfer is
45 °, lower end chamfer is 30 °.Circle is equipped with arc surface with 1 junction of centre tooth wheel body, and the two is excessive by arc surface.Outer ring
Medial surface both ends are equipped with chamfering, and chamfering is 45 °.Wearing layer is provided in gear.
The number of teeth is 56, and pressure angle is 20 °, reference diameter 192.08mm, and helical angle is 29 °.In addition, root circle is straight
Diameter is 184.43mm, and graduated arc transverse tooth thickness is 4.878mm.
The section of the tooth of outer ring is the isosceles trapezoid of two stackings, and the tooth socket between tooth is arc-shaped.
In short, the above is only the preferred embodiment of the present invention, it is all according to present utility model application the scope of the patents institute
The equivalent changes and modifications of work should all belong to the covering scope of the utility model patent.
