Description
Technical field
The utility model relates to a kind of cooling device, especially a kind of cooling end cap of labyrinth type.
Background technique
As the power density of power transmitting apparatus is continuously improved, high efficiency and heat radiation becomes the technology difficulty that must be solved
Topic.For the speed reducer of bath lubrication, speed reducer relies primarily on outside heat dissipation to realize the cooling of body, and unlikely makes to lubricate
The problems such as oil temperature is excessively high, generates viscosity decline, stability reduction, to make lubrication failure, threatens the reliable, steady of speed reducer
Fixed, high-efficiency operation.
Existing frequently-used cooling means has plus fan or cooling water pipe.The cooling efficiency of one side fan is relatively low, another
Aspect fan certainly will occupy certain space as additional cooling equipment, will also increase the complexity of equipment.Using fan
Cooling must be connected with ambient atmosphere, form the convection loop of air, and severe to confined space or operating condition is dusty,
Strong vibration environment is difficult to be applicable in.The present cooling water pipe type of cooling, mainly to coil pipe is arranged in speed reducer internal lubrication oil,
Heat exchange is generated by the lubricating oil in cooling water flow and speed reducer, to realize cooling, reduces speed reducer temperature rise.But this side
Formula implemented for this actuation types of on-fixed planetary reducer it is relatively difficult, since cooling coil directly invades unconcerned moistening
In lubricating oil, there are cooling water leakage risks, especially dusty, under strong vibration environment, work can high property substantially reduce.To pick
Into for the similar planetary reducer mobile with chassis of machine cutterhead speed reducer, with the raising of power density, proper lubrication
With a cooling even more severe challenge.
A kind of cooling efficiency is high, compact-sized, can be in dusty, strong vibration, confined space, the cooling of reliable efficient operation
Structure becomes technical problem urgently to be resolved.
Utility model content
The goal of the invention of the utility model is: it is low for the existing cooling efficiency that there is a problem of speed reducer, provide one
The cooling end cap of kind labyrinth type.
To achieve the goals above, what the utility model used is technical solution are as follows:
A kind of cooling end cap of labyrinth type, including cooling fin, end cap outer wall and end cap inner wall, described cooling fin one end and end cap
Outer wall is fixedly connected, and the cooling fin other end is fixedly connected with end cap inner wall, is provided with coolant liquid on the end cap outer wall and is entered
Mouth and outlet.
Further, the cooling end cap of the labyrinth type further includes end cover body, outside described end cover body one end and end cap outer wall
Anchor ring is fixedly connected, and the end cover body other end is fixedly connected with end cap inner wall outer ring surface, in this way, foring a confined air
Between, sealing effect is improved.
Further, the entrance is set at end cap inner annular edge, and the entrance is set at end cap outer wall inner annular edge,
The outlet is set to end cap outer wall outer ring edge, and the line of the entrance and exit is crossed the center line of end cap, is thus arranged
Entrance and exit position, cooling circulation area can be increased to greatest extent, it is making end cap to be handed over coolant liquid heat
It changes more completely.
Further, the cooling fin is annular sheet, and the cooling fin forms multilayer annulus knot using end cap central as the center of circle
Structure is provided with an opening on the annulus, and the line at the midpoint of the opening of two neighboring annulus crosses the center line of end cap, described
Entrance and adjacent cooling fin annulus maximum distance are opening position, the outlet and adjacent cooling fin annulus most long distance
From for the position that is open, the maze-type structure being thusly-formed increases cooling circulation area, and cooling effect is more preferable.
In conclusion due to the adoption of the above technical solution, the beneficial effect of the application is:
1. being capable of increasing the cooling circulation area in end cap by the installation cooling fin of annular, improving cooling efficiency.
2. the closed performance of end cap can be effectively improved by fixed end cover body, end cap inner wall and end cap outer wall.
