Fig. 1 is the structural schematic diagram of retarder 10 provided in this embodiment, and Fig. 2 is in retarder 10 provided in this embodiment
Input the structural schematic diagram of shell 200.Incorporated by reference to reference Fig. 1 and Fig. 2, a kind of retarder 10 is present embodiments provided comprising
Speed reducer 100 (rear to be described in detail) and input shell 200, input shell 200 are mounted on speed reducer 100.Specifically, the input shell
The structure of body 200 is as follows:
Input shell 200 includes ontology 210 and the permeability cell 220 that is connected on ontology 210, one end of ontology 210 with
Speed reducer 100 connects, and the other end with actuator for connecting, and in the present embodiment, actuator is motor.It is opened up on ontology 210
There is the swollen chamber 211 of oil, oil is swollen, and chamber 211 is connected to the installation cavity of speed reducer 100, so that temperature increases Shi Weirun in speed reducer 100
Lubricating oil provides expansion space, and then guarantees that speed reducer 100 can satisfy lubricating requirement.One end of permeability cell 220 and the swollen chamber 211 of oil
Connection, thus in 100 operational process of speed reducer, gas can pass in and out speed reducer 100 by permeability cell 220, permeability cell 220 it is another
One end forms venthole 222, and the height of venthole 222 is higher than the height of permeability cell 220 and swollen 211 connectivity part of chamber of oil, therefore oil
It steeps or mixes aerial mist of oil etc. after entering permeability cell 220 with air, it can be along ventilative before being left from venthole 222
220 inner wall cooling for reflux of pipe, avoids lubricating oil from spraying, and good lubricant effect can be obtained by further ensuring speed reducer 100,
To facilitate the service life of prolonged deceleration machine 100.
Retarder 10 provided in this embodiment is further described below:
Continuing with combining referring to Figures 1 and 2, ontology 210 is circular tube shaped, and oily swollen chamber 211 is the internal cavities of ontology 210,
And open at both ends is arranged, and is respectively formed the first opening 212 and the second opening 213.First opening 212 is located at the second opening 213
Lower section.Input shell 200 is mounted on the input end of speed reducer 100, and the swollen chamber 211 of oil by the first opening 212 and slows down
The installation cavity of machine 100 is connected to.Speed reducer 100 includes reducer shell 110 and reduction assemblies, the installation cavity shape of speed reducer 100
At in reducer shell 110, reduction assemblies are mounted in installation cavity.The input shaft 120 of reduction assemblies passes through the first opening 212
Into in the swollen chamber 211 of oil.(not shown go out) is mounted on the input one end of shell 200 far from speed reducer 100 in use, motor, and
The output shaft (not shown go out) of motor passes through the second opening 213 and enters in the swollen chamber 211 of oil, to realize the biography with input shaft 120
Dynamic connection.Optionally, input shaft 120 is driven with output shaft by spline fitted.
When temperature raising, gas expansion in speed reducer 100, it is swollen that oily swollen chamber 211 can provide enough oil for lubricating oil
Space avoids increasing because of 100 internal temperature of speed reducer, and lubricating oil is caused to expand the problem of overflowing, and guarantees in speed reducer 100
Lubricating oil is capable of providing enough lubricant effects, satisfies the use demand.
Fig. 3 is the partial structurtes enlarged diagram in Fig. 2 at III.It is in the present embodiment, defeated incorporated by reference to reference Fig. 2 and Fig. 3

Air pressure balance in chamber 211.The height of venthole 222 is higher than the height of permeability cell 220 and swollen 211 connectivity part of chamber of oil, therefore when mixed
It closes after aerial mist of oil or oil vacuole etc. enter permeability cell 220 with air, and is leaving input shell from venthole 222
Before 200, lubricating oil can further avoid lubricating oil ejection, guarantee speed reducer along the cooling oil return of the inner wall of permeability cell 220
The volume of lubricating oil can satisfy the lubrication needs of reduction assemblies in 100, to facilitate the use longevity of prolonged deceleration machine 100
Life.
Further, the height of venthole 222 is higher than the height of swollen 211 highest point of chamber of oil.Due to the height of venthole 222
Higher than the height of swollen 211 highest point of chamber of oil, air pressure requirement needed for lubricating oil enters permeability cell 220 is higher, thus lubricating oil into
A possibility that entering permeability cell 220 and spraying eventually by venthole 222 is smaller, further ensures and lubricating oil is avoided to spray feelings
The generation of condition, while also to provide enough distances into the lubricating oil of permeability cell 220, to guarantee that lubricating oil can be along ventilative
The cooling oil return of the inner wall of pipe 220, thus helps to ensure that lubricant effect.
In the present embodiment, air hole 214 is offered on ontology 210, the one end of permeability cell 220 far from venthole 222 is
Installation end, installation end removably cooperate with air hole 214.It is opened specifically, air hole 214 is provided with ontology 210 close to second
On the wall surface of mouth 213, the position of air hole 214 is the position of permeability cell 220 and swollen 211 connectivity part of chamber of oil.
Fig. 4 is the partial structurtes enlarged diagram in Fig. 2 at IV.Incorporated by reference to referring to Fig. 3 and Fig. 4, further, shell is inputted
Body 200 further includes plug cock 230.The quantity of air hole 214 be it is multiple, multiple air holes 214 are uniformly opened up along the circumferential direction of ontology 210
In ontology 210 close to one end of the second opening 213.In use, permeability cell 220 is selectively matched with one of air hole 214
It closes, remaining air hole 214 cooperates with corresponding plug cock 230, to be closed remaining air hole 214 by plug cock 230.To
When in use, user can select the air hole 214 of suitable position to install permeability cell 220 according to demand, avoid permeability cell 220 and its
His component interferes, to impact to the work of retarder 10.
