Description

Servomotor

Technical field

This utility model relates to machine field, particularly to a kind of servomotor.

Background technology

Motor is a kind of common power source, and range of application is quite varied, generally includes polytype, such as stepping electricity Machine, servomotor etc.；Wherein, servomotor, by voltage signal being converted into torque and rotating speed to drive control object, controls Speed and positional precision are accurate, the important component part being normally used as in servosystem, it is achieved power exports；Due to servo electricity Machine needs to meet the demand that runs up, therefore, to the cooling of servomotor with dispel the heat extremely important, especially for high-power For servomotor, the heat radiation in its running is directly connected to its service life, if operating temperature is too high, it is possible that Fault, reduction of service life, although be provided with cooling system in the existing servomotor of part, but radiating effect is limited, in pole Under end operating mode, still it is difficult to meet radiating requirements.

Utility model content

In order to solve above-mentioned technical problem, this utility model provides a kind of servomotor, can improve the heat radiation effect of motor Really, increase the service life.

Servomotor of the present utility model, including stator, rotor, rotating shaft, housing, flabellum and heat abstractor, described stator, Rotor and flabellum are all located in housing, and described rotating shaft passes rotor and two ends by bearing bracket stand on housing, and described flabellum is installed Rotation is driven in rotating shaft front end and by rotating shaft；Described heat abstractor includes the radiating sleeve and being removably enclosed within outside housing Air pump, described radiating sleeve includes outer wall, inwall and the hot channel being located between outer wall and inwall, and described hot channel is with spiral Mode is wrapped on inwall, one end of described hot channel is connected with the air inlet pipe penetrating outer wall, the other end with penetrate outer wall Escape pipe is connected, and described air inlet pipe is connected with the outlet side of air pump, described escape pipe connection air.

The beneficial effects of the utility model: servomotor of the present utility model, flabellum together rotates with rotating shaft, rotation process Middle formation negative pressure, improves enclosure interior air-flow velocity, strengthens radiating effect；The heat of housing reaches radiating sleeve, due to radiating tube Road is wrapped on inwall, carries out heat exchange, to carry out housing with radiating sleeve when the air-flow that air pump produces flows in radiating tube Heat radiation；Additionally, due to hot channel is helically wound on inwall, can effectively extend the length of radiating tube, increase heat radiation Pipe and the contact surface of radiating sleeve, improving radiating effect, extend the service life of motor.

As further improving, the inner surface of described housing is provided with electromagnetism interference layer；Thus without additional at motor If an electromagnetism interference cover or electromagnetic interference resistant device, it is to avoid the waste in space, save space, and made housing be easier to dissipate Heat.

As further improving, described rotor is provided with corrugated heat dissipation channel vertically；This heat dissipation channel is near turning Son is peripheral, enhances the radiating effect of rotor, protects rotor, and then protect motor.

As further improving, described outer wall, inwall and hot channel all use heating resisting metal material to make, can be at height Normally using under temperature operating mode, heat conductivility is good simultaneously, is conducive to heat radiation, and intensity is higher, is hardly damaged.

Accompanying drawing explanation

In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, the accompanying drawing in describing below is only Embodiments more of the present utility model, for those of ordinary skill in the art, in the premise not paying creative work Under, it is also possible to other accompanying drawing is obtained according to these accompanying drawings.

Fig. 1 is the structural representation of the embodiment of the present application.

Detailed description of the invention

As it is shown in figure 1, in the preferred embodiment, servomotor includes stator 1, rotor 2, rotating shaft 3, housing 4, flabellum 5 And heat abstractor, described stator 1, rotor 2 and flabellum 5 be all located in housing 4, and described rotating shaft 3 passes through axle through rotor 2 and two ends Holding 10 framves on housing 4, described flabellum 5 is arranged on rotating shaft 3 front end and is driven rotation by rotating shaft 3；Described heat abstractor include with Removably is enclosed within the radiating sleeve outside housing 4 and an air pump 7, and described radiating sleeve includes outer wall 61, inwall 62 and is located at outer wall Hot channel 63 between 61 and inwall 62, described hot channel 63 is helically wound on inwall 62, described radiating tube The one end in road 63 is connected with the air inlet pipe 81 penetrating outer wall 61, the other end is connected with the escape pipe 82 penetrating outer wall 61, described in enter Trachea 81 is connected with the outlet side of air pump 7, and described escape pipe 82 connects air；Radiating sleeve can by being spirally connected, the mode such as clamping even It is connected on housing 4；The inner surface of described housing 4 is provided with electromagnetism interference layer (not shown)；Described rotor 2 is provided with vertically Corrugated heat dissipation channel 9；Described outer wall 61, inwall 62 and hot channel 63 all use heating resisting metal material to make；Flabellum 5 with Rotating shaft 3 together rotates, and forms negative pressure, improves housing 4 internal gas flow flow velocity, strengthen radiating effect in rotation process；The heat of housing 4 Amount reaches radiating sleeve, owing to hot channel 63 is wrapped on inwall 62, with scattered when the air-flow that air pump 7 produces flows in radiating tube Hot jacket carries out heat exchange, to dispel the heat housing 4；Additionally, due to hot channel 63 is helically wound on inwall 62, Can effectively extend the length of radiating tube, increase the contact surface of radiating tube and radiating sleeve, improving radiating effect, extend the use of motor Life-span.
