In use, the content needs of the lubricating oil in retarder reach the height close to 4 axis of semiaxis, at this point, velocity-reducing chamber 6 and lubricating oil
Contain lubricating oil in channel 7, lubricating oil can absorb the heat that retarder work generates, and the intracorporal heat conduction velocity of liquid is big
Therefore heat conduction velocity in air is clamped grease channel 7 by first passage 1021 and second channel 1022, cold
But liquid can carry out heat exchange with the lubricating oil in grease channel 7 simultaneously from two sides, so as to improve lubrication when passing through
Rate of heat exchange between oil and coolant liquid, in addition, second channel 1022 and velocity-reducing chamber 6 are close to cold in second channel 1022
But liquid can carry out heat exchange with the high temperature in velocity-reducing chamber 6, and therefore, the setting of first passage 1021 and second channel 1022 can
So that coolant liquid and retarder carry out sufficient heat exchange, so as to improve cooling effect.
Several first heat conducting bars 13 are plugged in the shell 1, one end of each first heat conducting bar 13 is respectively positioned on
In velocity-reducing chamber 6, the other end of each first heat conducting bar 13 sequentially passes through first passage 1021 and grease channel 7 and extends
In second channel 1022；In the present invention, the first heat conducting bar 13 is made of the preferable material of heat conductivity, passes through the first heat conducting bar 13
Effect the heat in velocity-reducing chamber 6 and grease channel 7 can be transmitted to first passage by first heat conducting bar 13
1021 and second channel 1022 in, then thermally conductive dry connect with the coolant liquid in first passage 1021 and second channel 1022 by first
Touching, can further increase coolant liquid to the cooling effect of retarder.
The cooling mechanism 11 includes cooling slot 111 and cooling fin 112, and the cooling slot 111 is arranged on shell 1, institute
State cooling fin 112 be set on corresponding semiaxis 4 and cooling fin 112 be located at cooling slot 111 in, the two sides of the cooling fin 112
It is rotatablely connected with shell 1 by bearing, is provided with several heat release holes 113, the cooling fin 112 on the cooling fin 112
Side wall be equipped with several fan blades 114 for being circumferentially distributed；When in use, semiaxis 4 can rotate drive cooling fin to retarder
112 rotations are formed around firstly, the heat on semiaxis 4 can be transmitted on cooling fin 112, then rotated by cooling fin 112
Air-flow, so as to quickly remove the heat on semiaxis 4, the setting of heat release hole 113 is, when cooling fin 112 is in rotation,
The air-flow of two sides can be different, to generate pressure difference, and then can further increase the heat dissipation effect of cooling fin 112, fan blades 114
Setting be, when cooling fin 112 rotate when, will drive fan blades 114 rotation, fan blades 114 rotate when air can be dispelled out outward
Go, thus fan blades 114 middle part and around formed draught head, and then formed air-flow, cooling fin 112 can be further increased
Heat dissipation effect.
The side wall of the cooling slot 111 is equipped with several second heat conducting bars 14, one end position of second heat conducting bar 14
In in cooling slot 111, the other end of second heat conducting bar 14 through shell 1 and is extended in velocity-reducing chamber 6；Second heat conducting bar 14
Work be the position that the heat in velocity-reducing chamber 6 can be led to cooling fin 112, then by cooling fin 112 rotation can be quick
Heat is distributed, to play the heat dissipation effect to retarder.
The air cooling mechanism 12 includes fan 121 and fan board 122, and the shell 1 is equipped with air-cooled slot 123, the wind
Fan 121 is arranged on driving shaft 2, and the two sides of fan 121 are rotatablely connected with shell 1 by bearing, before the fan 121
End is arranged towards shell 1, and the fan board 122 is fixedly connected with shell 1 and fan 121 is located at the outside of fan 121；Work as deceleration
When device works, the rotation of drive shaft 2 will drive the rotation of fan 121, and the rotation of fan 121 can blow away air-flow towards retarder, so as to
It is enough that the dispersion of cooling fin 112 is come out and be centered around the heat around retarder and dispel and come, it can more effectively help to cool down
Mechanism 11 works, and improves retarder heat dissipation effect.
Working principle: when retarder is worked, cooling fin 112 is driven to rotate firstly, semiaxis 4 can rotate, and half
Heat on axis 4 can be transmitted on cooling fin 112, then be rotated by cooling fin 112, form air-flow, around so as to fast
Speed disperses the heat on semiaxis 4；Meanwhile when the rotation of cooling fin 112, the rotation of fan blades 114 will drive, when fan blades 114 rotates
Air can be dispelled away outward, thus fan blades 114 middle part with around formed draught head, and then formation air-flow, Neng Goujin
The heat dissipation effect of one step raising cooling fin 112.In addition, the rotation of drive shaft 2 will drive the rotation of fan 121, the rotation of fan 121 can court
Retarder blow away air-flow, so as to that the dispersion of cooling fin 112 is come out and be centered around the heat around retarder and dispel out
Come, cooling mechanism 11 can more effectively be helped to work, improves retarder heat dissipation effect.If cooling mechanism 11 and air cooling mechanism 12
When enough to the cooling effect of retarder, Water-cooling circulating mechanism 10 then causes to cool down without work if weather temperature is higher
Mechanism 11 and air cooling mechanism 12 are insufficient to the cooling effect of retarder, and Water-cooling circulating mechanism 10 works, logical by water inlet port 101
Enter coolant liquid, when coolant liquid passes through water passage 102, carries out heat exchange with shell 1, absorb the heat inside retarder, logical
It crosses water outlet port 103 coolant liquid is discharged, to be taken away the heat in retarder by coolant liquid, plays and cool down to retarder
Effect.
