Description
Technical field
The present invention relates to a kind of motorized pulleys, particularly relate to a kind of built-in motor and with the motorized pulleys of oil sealer.
Background technology
The inner integrated electric motor of common motorized pulleys, can realize autonomous rotation, therefore volume is little, save space, and its electrical motor, transmission system are all integrated in the inner barrel of sealing, are therefore not easily affected by the external environment, adaptable, not fragile, long service life.
And the open oil immersion motor that motorized pulleys inside is installed, parts of lubricating oil can have been filled with in barrel, cylindrical shell lubricating oil in rotation process can flow inside and outside oil immersion motor, for lubricating the moving part of motor, the heat energy that the heat generating components of motor produces is directed at drum surface simultaneously, is distributed by cylindrical shell.
Cylindrical shell is originally as full-closed structure, and the power supply of motor must be accessed by outside, and therefore the power supply fixture wire of motor also must do Seal treatment.In the course of the work, motor can produce heat to motorized pulleys, the lubricating oil in this heat meeting heating cylinder and air, make inner barrel pressure increase, lubricating oil can from the gap of power lead to outer seepage, Long-Time Service can make these seepages formed oil droplet, cause conveying article pollute.There is no the solution of this respect at present.
Summary of the invention
The present invention for solving prior art problem, provide a kind of reliability high, can not the motorized pulleys of built-in motor of seepage.
Technical scheme of the present invention is: a kind of motorized pulleys of built-in motor, comprise columniform cylindrical shell, open motor is provided with in described cylindrical shell, described cylindrical shell two ends are provided with for will the end cap of mutually sealing inside and outside cylindrical shell, fill with in described cylindrical shell have can inside and outside described open motor free-pouring lubricating oil; End cap described in one of them is wire end cap, and the central axis of described wire end cap is provided with the guide hole for the cable by described open motor, and described cable comprises seal section and non-tight section; Described seal section comprises sealing conductor and is fixedly arranged on the outer and sealed insulation block fitted tightly with sealing conductor of sealing conductor, and described non-tight section comprises the non-tight conductor be connected with described sealing conductor electrical and the non-tight insulating barrier be wrapped in outside this non-tight conductor; Described sealed insulation block and described sealing conductor seal fits.
As preferably, in described sealed insulation block, have conductor chamber; The volume in described conductor chamber is identical with shape with the volume of described sealing conductor with shape.
As preferably, between the outside face of the part of described cable in described guide hole and the inside face of described guide hole, be provided with sealing member.
As preferably, described cable comprises the wire of several mutually insulated, and the quantity of this wire is the integral multiple of three.
As preferably, the quantity of described sealed insulation body is identical with the quantity of described wire.
As preferably, described sealed insulation body is cylindrical or cuboid.
As preferably, the outside face of described sealed insulation block and the inside face of described guide hole seal fits.
As preferably, the rotor that the output shaft that described open motor comprises motor open with this is fixedly connected with, and the stator be fixedly connected with described wire end cap; Described stator is outside equipped with the motor housing of hollow out.
As preferably, described non-tight insulating barrier comprises inner insulating layer and external insulation layer, and described inner insulating layer is insulating lacquer layer.
In sum, the gap of power lead is mainly formed by the space between the copper wire in wire and the space between copper wire and the outer rubber of wire, and the present invention increases a sealed insulation block on lead-in wire, and sealing collets can by insulating resin cast molding.When insulating resin is liquid, insulating resin can go deep in the gap of power lead, when after insulating resin solidification, can be full of these gaps, makes these gaps can not seepage lubricating oil, thoroughly blocks the path of lubricating oil.
Therefore the present invention has the following advantages:
1, block the path of lubricating oil, good airproof performance inside and outside cylindrical shell, can not produce seepage;
2, the wire be dipped in lubricating oil is enamel wire, and not easily lubricated oil corrodes compared with the rubber insulating barrier of common rubber wire, long service life.
