Description

The motor that a kind of shale electric drill is used

Technical field

The utility model relates to the mining machinery field, the motor that particularly a kind of shale electric drill is used.

Background technology

In the prior art, be used for the electric drill of rock mining boring, because the speed reducing ratio of its inner deceleration device is too little, thereby its rotating speed is generally higher, is suitable for using in harder rock and the mine.When being used to exploit the lower and drilling cuttings end of hardness and having the purple shale of viscosity, the phenomenon of viscous drill bit takes place easily, influence is normally used.

Summary of the invention

At the existing deficiency of existing product, technical problem to be solved in the utility model provides the motor that a kind of rotating speed is lower, its supporting electric drill can be fit to the exploitation of purple shale.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is the motor that a kind of shale electric drill of design is used: comprise casing 14, stator 8, rotor 10, bottom end cover 9 and upper end cover 11; The inner chamber of casing 14 installs stator 8 and rotor 10 successively; Bottom end cover 9 and upper end cover 11 install the two ends up and down at casing 14 respectively; Also include the planet circular system deceleration device that constitutes by rotor axle sleeve 13, central gear 7, planet pin 5, planetary gear 6, ring gear 4, pivoted arm 3, pivoted housing 1 and gear box cover 2 and upward auxiliary end cap 12; Rotor axle sleeve 13 devices are at the center of rotor 10, and it is end device central gear 7 down; Extend downwards the bottom of casing 14, this extending part device ring gear 4; Pivoted housing 1 device is in the axis hole of rotor axle sleeve 13, and it is end device pivoted arm 3 down, and the end fitting planet pin 5 of this pivoted arm 3, planetary gear 6 are sleeved on the planet pin 5; Planetary gear 6 is between ring gear 4 and the central gear 7, with ring gear 4 and central gear 7 engagements; Gear box cover 2 devices cover pivoted arm 3 in the bottom of casing 14; Go up auxiliary end cap 12 devices on upper end cover 11.

The motor that shale electric drill of the present utility model is used adopt the bigger planet circular system deceleration device of speed reducing ratio to slow down, thereby its rotating speed is lower, so the electric drill supporting with it can be fit to the exploitation of purple shale.

Among the figure: the 1st, pivoted housing, the 2nd, gear box cover, the 3rd, pivoted arm, the 4th, ring gear, the 5th, planet pin, the 6th, planetary gear, the 7th, central gear, the 8th, stator, the 9th, bottom end cover, the 10th, rotor, the 11st, upper end cover, the 12nd, go up auxiliary end cap, the 13rd, rotor axle sleeve, the 14th, casing.

Embodiment

Below in conjunction with drawings and Examples, the utility model is further described.

Present embodiment is by casing 14, stator 8, rotor 10, bottom end cover 9, upper end cover 11, rotor axle sleeve 13, central gear 7, planet pin 5, planetary gear 6, ring gear 4, pivoted arm 3, pivoted housing 1, gear box cover 2 and goes up and assist end cap 12 to constitute.

Casing 14 is cylindric, and the upper end has the inner stopper step, and the lower end has inside and outside two-stage inner stopper step; The inner chamber of casing 14 installs stator 8 and rotor 10 successively, and rotor axle sleeve 13 fixtures are at the center of rotor 10; The two ends of rotor axle sleeve 13 are respectively by bottom end cover 9 and upper end cover 11 location of device at casing two ends about in the of 14; Bottom end cover 9 device is on the inner inner stopper step in casing 14 lower ends, and upper end cover 11 devices are on casing 14 upper end inner stopper steps.

Pivoted housing 1 device in the axis hole of rotor axle sleeve 13, after upper end cover 11 is stretched out in its upper end, by device on upper end cover 11 on auxiliary end cap 12 locate; After the lower end of rotor axle sleeve 13 passes bottom end cover 9, its end fixture central gear 7.The outward flange device of ring gear 4 is on the outer inner stopper step in casing 14 lower ends, (this planetary gear 6 can adopt one or two even three or four to device planetary gear 6 between the internal tooth of ring gear 4 and the central gear 7, present embodiment adopts two), and this planetary gear 6 simultaneously with the internal tooth and central gear 7 engagements of ring gear 4.Planet pin 5 is equipped with at the center of planetary gear 6, and the following end device of this planet pin 5 is in the end of pivoted arm 3.On the pivoted housing 1 that the centre bore fixture of pivoted arm 3 extends out in the axis hole by rotor axle sleeve 13, the lower end of pivoted housing 1 is by the central shaft hole location of gear box cover 2, gear box cover 2 devices all cover central gear 7, planet pin 5, planetary gear 6, ring gear 4 and pivoted arm 3 on the outward flange of ring gear 4.Central gear 7, planet pin 5, planetary gear 6, ring gear 4 and pivoted arm 3 constitute planet circular system.Pivoted housing 1 is as the power output shaft of motor.

During use, need the utility model and other is kitting.Only the operation principle of this motor is described further below.

When electric motor starting, its rotor 10 drives rotor axle sleeve 13 and rotates, and then drives central gear 7 rotations; Because ring gear 4 is not active, rotate (rotation of this moment is slowed down through planet circular system, and its rotating speed is lower) with planet pin 5 together with pivoted arm 3 with 6 of ring gear 4 and central gear 7 planet gear meshed; The rotation of pivoted arm 3 drives pivoted housing 1 again and rotates, thereby by the lower power of pivoted housing 1 output speed.

The motor that shale electric drill of the present utility model is used with other kitting electric drill of making, can be fit to drill the less purple shale of hardness and other mineral, also can be used for drilling bigger rock of hardness and mineral.
