Description
Technical field
The utility model relates to a kind of planetary reducer, especially a kind of planetary reducer of automatic heat radiation.
Background technique
Planetary reducer is a kind of reducing gear playing deceleration, increase square effect, in the process that planetary reducer runs up, easily a large amount of heats is produced between the planetary pinion of phase mutual friction, if do not distributed in time, the easy normal performance affecting retarder, present planetary reducer is all generally dispelled the heat by cooling liquid or cold water, and in the structure of retarder self and without heat sinking function, if artificial maintenance or supervision are not, retarder is easily heating just, will break down time serious, bring inconvenience to normal production technology.
Model utility content
The purpose of this utility model is the defect in order to solve in prior art existing for planetary reducer, provides a kind of planetary reducer of automatic heat radiation.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of planetary reducer of automatic heat radiation, comprise the retarder end cap that is connected with motor and be arranged on the multiple gear trains be connected with retarder end cap in reducer shell, this gear train comprises multiple planetary pinion and the planetary carrier with a sun gear, multiple bearing pins on planetary carrier are connected with multiple planetary pinions of its side respectively, sun gear on planetary carrier engages with the multiple planetary pinions on its opposite side gear train, described retarder end cap comprises mutually socket and the inner casing that connected by multiple stiffening rib of side face and shell in opposite directions, described inner casing outer wall and outer casing inner wall are provided with some radial directions and extend and interlaced radiating fin, heat dissipation channel is formed between adjacent radiating fin, the air guide channel prolonging its width direction and extend is provided with between teeth adjacent between two outside described planetary pinion, this air guide channel and described heat dissipation channel are parallel to each other.
The planetary reducer of above-mentioned a kind of automatic heat radiation, described retarder end cap is with the flange that contact open-ended with reducer shell, described reducer shell is provided with fixed hole, fixed hole is equipped with set screw, the end of this set screw and the circumferential contact of described retarder end cap upper flange.
The planetary reducer of above-mentioned a kind of automatic heat radiation, the planetary quantity on described planetary carrier is three.
The planetary reducer of above-mentioned a kind of automatic heat radiation, the fixed hole on described reducer shell and set screw are arranged on the two ends of reducer shell.
The planetary reducer of above-mentioned a kind of automatic heat radiation, the cross section semicircular in shape of described air guide channel.
The beneficial effects of the utility model are: the retarder end cap at these planetary reducer two ends is dispelled the heat by the radiating fin on inner casing and shell, the heat dissipation channel that hot air flow is formed between adjacent heat radiation fin flows out toward both sides, extraneous new cold airflow pours in heat dissipation channel, go round and begin again, the circulation defining hot and cold air exchanges, and outside each planetary pinion, between adjacent between two teeth, be provided with the air guide channel prolonging its width direction and extend, this air guide channel and heat dissipation channel are parallel to each other, the retarder end cap at reducer shell two ends carries out air-flow exchange by the air guide channel on planetary pinion be communicated with, radiating effect is fine.
Accompanying drawing explanation
