Description

A kind of planetary reducer of automatic heat radiation
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
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is the schematic diagram of the utility model retarder end cap;
Fig. 3 is the planetary schematic diagram of the utility model.
Embodiment
Further understand for making to have structure characteristic of the present utility model and effect of reaching and be familiar with, coordinate detailed description in order to preferred embodiment and accompanying drawing, be described as follows:
As shown in Figure 1 to Figure 3, a kind of planetary reducer of automatic heat radiation, comprise the retarder end cap 2 that is connected with motor 1 and be arranged on the multiple gear trains be connected with retarder end cap in reducer shell 3, this gear train comprises multiple planetary pinion 4 and the planetary carrier 6 with a sun gear 5, multiple bearing pins 7 on planetary carrier 6 are connected with multiple planetary pinions 4 of its side respectively, sun gear 5 on planetary carrier 6 engages with the multiple planetary pinions 4 on its opposite side gear train, retarder end cap 2 comprises mutually socket and the inner casing 8 that connected by multiple stiffening rib of side face and shell 9 in opposite directions, inner casing 8 outer wall and shell 9 inwall are provided with some radial directions and extend and interlaced radiating fin, heat dissipation channel 10 is formed between adjacent radiating fin, the air guide channel 11 prolonging its width direction and extend is provided with between teeth adjacent between two outside planetary pinion 4, this air guide channel 11 is parallel to each other with described heat dissipation channel 10.
Further, retarder end cap 2 is with the flange 12 that contact open-ended with reducer shell 3, reducer shell 3 is provided with fixed hole, fixed hole is equipped with set screw 13, the end of this set screw 13 and the circumferential contact of retarder end cap 2 upper flange 12, after retarder inner planet gear frame 6 and planetary pinion 4 installation, cover retarder end cap 2, directly extruded by the set screw 13 on reducer shell 3, the flange 12 of fastening retarder end cap 2, this means of fixation makes retarder end cap have certain axial tensile force, when component in reducer shell produces and axially rocks, the axis increased between each component rocks displacement, reduce the noise produced because of collision,
The retarder end cap 2 at these planetary reducer two ends is dispelled the heat by the radiating fin on inner casing 8 and shell 9, the heat dissipation channel 10 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 4, between adjacent between two teeth, be provided with the air guide channel 11 prolonging its width direction and extend, this air guide channel 11 is parallel to each other with heat dissipation channel 10, the retarder end cap 2 at reducer shell 3 two ends carries out air-flow exchange by the air guide channel 11 on planetary pinion 4 be communicated with, radiating effect is fine.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; the just principle of the present utility model described in above-described embodiment and specification; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
