On the end face of upper box and lower box and it is open and arranges towards in casing, the sealed liner extends by opening towards in casing,
Space is left between the opening of depth of the thickness of the sealed liner higher than ladder mouth, the sealed liner and ladder mouth,
The ladder mouth is provided with the projection contacted with sealed liner adaptation, when the upper box and lower box seal against each other connection, institute
State sealed liner and be resilient extruding contact；The radiator structure is the curvilinear hot channel around lower box outer wall.
This utility model is further arranged to：The hot channel is provided with multiple and is equipped with inlet and outlet, described enter
Rational height of the rational height of mouth higher than outlet.
This utility model is further arranged to：The radiator structure is adopted and uses water as circulation medium.
This utility model is further arranged to：The sealed liner is made using polytetrafluoroethylmaterial material.
This utility model is further arranged to：The sealed liner is pasted onto on ladder mouth by glue.
This utility model is further arranged to：Some reinforcements are equipped with the upper box and lower box.
This utility model is further arranged to：The upper box and lower box seal against each other connection by screw.
The beneficial effects of the utility model：The reductor that this utility model is provided changes existing box body of speed reducer internal gear
The set-up mode that group triangle or axis are all arranged parallel to each other in same level, but all gears are set to which most
In same level, such set-up mode not only reduces space to the line of the minimum point in outside, it is often more important that all gears
Lubricating oil is touched simultaneously can, the rotation work for gear provides more preferable lubricant effect；This utility model to upper box and
Being tightly connected between lower box has made further improvement, arranges ladder mouth, Ran Hou first on the end face of upper lower box
Sealed liner of the thickness higher than the elasticity of ladder mouth is pasted on ladder mouth, when upper box and lower box seal against each other connection, sealing
Lining mutually extrudes generation creep, and space provides utilization space for the pressurized creep diffusion of sealed liner, on ladder mouth
Projection serve positioning action for creep direction, make lower box formed when being connected with each other close, rigid be tightly connected, this
The setting of sample avoids lubricating oil in casing from wasting, and extends the Use Limitation of lubricating oil, protects gear；On the lower box outer wall
It is additionally provided with radiator structure and adopts and use water as circulation medium, is not only simple in structure low cost, and can quickly disperse casing table
The heat in face.
