Abstract
The invention discloses a planetary mechanism of a drum coal shearer. The planetary mechanism of a drum coal shearer comprises a sun gear, a planetary gear set, an internal ring gear, a planetary carrier, a gland, bolts, a bearing base and a bearing, wherein the planetary gear set is installed on the planetary carrier and is installed inside the internal ring gear together with the sun gear; the bearing is installed inside the bearing base and is installed on the internal ring gear together with the bearing base; the inner side of the bearing is matched with the planetary carrier and is fixed through the gland; the gland is fixed on the internal ring gear of the planetary mechanism through the bolts; and the internal ring gear of the planetary mechanism is fixed on a rocker arm shell through the bolt 1 and the bolt 2 and a locking nut. The external diameter of the planetary mechanism is reduced and the coal loading effect of a drum is improved mainly by changing the structures of the internal ring gear and components matched with the internal ring gear.
Description
Technical field
The present invention relates to the cutting portion of the coal winning machine in machine technology field, colliery, particularly the planetary mechanism of drum shearer.
Background technique
Existing drum shearer in order to adapt to the special geologic condition of girdle and ultra-thin coal seam, also will guarantee enough big cut power when forcing down machine height.In order to guarantee that cylinder has enough big clipping force, common through increasing the realization recently of slowing down, common cutting portion ways of deceleration has two kinds: 1, the transmission of one-level straight-tooth adds the deceleration of two-stage planetary mechanism; 2, two-stage or three grades of straight-tooth transmissions add the deceleration of one-level planetary mechanism.
At present, the structure of the planetary mechanism that drum shearer is conventional, as shown in Figure 1.In the exploitation work of girdle, because the external diameter of planetary mechanism is bigger, makes that the degree of depth of the helical blade on the cylinder is less relatively, thereby influence the effect of loading coal of coal mining machine roller, influence coal mining output.
Summary of the invention
In order to overcome above-mentioned defective, the present invention provides a kind of can effectively reduce the outside dimension of planetary mechanism, thereby improves effect of loading coal, improves the planetary mechanism of the drum shearer of coal mining output.
The present invention for the technological scheme that solves its technical problem and adopt is: a kind of planetary mechanism of drum shearer, comprise sun gear, planetary gear set, ring gear, planet carrier, gland, screw, bearing support and bearing, and planetary gear set is contained on the planet carrier and together packs in the ring gear with sun gear; Sun gear and planetary gear set engagement, planetary gear set and ring gear engagement, Bearing Installation is in bearing support; And together be installed on the ring gear; And the inboard of bearing cooperates with planet carrier, and bearing and bearing support are fixed through gland, and said gland passes through screw on the ring gear of planetary mechanism; Said ring gear is fixed on the rocking arm housing through bolt one, bolt two and locking nut; Bolt one is used with locking nut, and the rocking arm housing is provided with the interior threaded hole that matches and use with the outside thread of bolt two, and bolt two is directly twisted solid on the rocking arm housing; Through the structure of change ring gear and parts with matching, thereby reach the purpose that reduces the planetary mechanism outside dimension.
As further improvement of the present invention, the form structure of said ring gear is a T shape, and it is arranged to T shape, has changed the structure of the parts that match with ring gear simultaneously, has effectively reduced the planetary mechanism outside dimension.
The present invention is mainly through changing the structure of winning machine cutting part upper planet mechanism ring gear; Diameter of movement in the roller tube of packing into is reduced; Relative increase the degree of depth of cylinder helical blade, reduce the planetary mechanism external diameter thereby reached, improved the efficient of coalingging of cylinder.
