A stator, a rotor, a coil and a motor shaft are arranged in the engine base, a junction box is arranged on the engine base, and the front end of the motor shaft is equipped with an annular shaft outer cover of which the outer side surface is equipped with a segment of positioning seam allowance; the shaft outer cover is equipped with a horizontal radial connecting hole and a vertical downwards radial connecting hole, an oil injecting pipe is connected with the horizontal radial connecting hole, and an oil discharging pipe is connected with the vertical downwards radial connecting hole. On the basis of an original blower fan explosion suppression type three-phase asynchronous motor, the blower fan explosion suppression type three-phase asynchronous motor supporting the use of the mining blower fan of the utility model enables the shaft outer cover to be improved, the outer side surface of the shaft outer cover is equipped with the positioning seam allowance, and the oil injecting pipe and the oil discharging pipe are connected on the shaft outer cover, so that the requirement is satisfied that clients are convenient to install a braking device, and the horizontal oil-feeding and vertical oil-discharging requirements are satisfied.
Description
Technical field
The utility model relates to the necessary electromotor of mine ventilator, relates in particular to the supporting explosion-proof type three-phase asynchronous motor used for fan of a kind of mine ventilator.
Background technology
Flame-Proof Three-Phase Induction Motors is totally-enclosed from fanning cold cage modle flame proof asynchronous motor, meets the ZBK25002-1989 standard.That this motor has is efficient, energy-conservation, margin of temperature rise reach greatly the life-span long, performance good, noise is low, little, the reliability high of vibration.
Wherein YBF2 series is the special-purpose Flame-Proof Three-Phase Induction Motors of blower fan, the YBF2-200-4.6.8P explosion-proof type three-phase asynchronous motor used for fan of present common use as illustrated in fig. 1 and 2, comprise support, stator, rotor, coil and motor shaft are installed in support, at support terminal box are installed.But the special-purpose Flame-Proof Three-Phase Induction Motors of this blower fan is without this positioning spigot, and the injection-discharge oil device of horizontal oil-feed, vertical oil extraction is not set, when brake gear is installed, need to connect in addition keeper, take larger installing space, be not easy to the installation of brake gear.
The utility model content
For the problems referred to above, the explosion-proof type three-phase asynchronous motor used for fan that provides a kind of mine ventilator supporting is provided the purpose of this utility model, to satisfy the convenient demand that brake gear and horizontal oil-feed, vertical oil extraction are installed of client.
To achieve these goals, the technical solution of the utility model is as follows:
The explosion-proof type three-phase asynchronous motor used for fan that mine ventilator is supporting, comprise support, stator, rotor, coil and motor shaft are installed in support, at support terminal box is installed, the front end of described motor shaft is provided with the axle enclosing cover of annular, it is characterized in that, be provided with one section positioning spigot on the lateral surface of described axle enclosing cover; Described axle covers outward and is provided with horizontal radial connecting hole and radially connecting hole vertically downward; One oil fuel tube is connected with the horizontal radial connecting hole, and an oil exit pipe is connected with vertically downward radially connecting hole.
In preferred embodiment of the present utility model, described horizontal radial connecting hole has two, a left side horizontal radial connecting hole, and one is right side horizontal radial connecting hole.
In preferred embodiment of the present utility model, described positioning spigot and the bearing cap structure that is formed in one.
The utility model improves the axle enclosing cover on original explosion-proof type three-phase asynchronous motor used for fan basis, is provided with positioning spigot on the lateral surface of this axle enclosing cover; Axle covers outward and is connected with oil fuel tube and oil exit pipe, satisfies the convenient demand that brake gear and horizontal oil-feed, vertical oil extraction are installed of client.
Positioning spigot of the present utility model and bearing cap are designed to one, and be simple in structure, intensity is higher, saves client's installing space, makes client's blower fan structure compacter.
Characteristics of the present utility model can be consulted the detailed description of the graphic and following better execution mode of this case and be obtained to be well understood to.
