Abstract
A transverse rotary drum connection device of a coal mining machine utilizes the straight-through type integration technical scheme that a transmission shaft is transversely fixed on a housing of a rocker gearbox housing through a shaft sleeve, a bearing and a gearbox end cover, the middle portion of the transmission shaft, which is in the gearbox housing, is connected with a transmission gear through a keyway, and the portion of the transmission shaft, which is on both sides of the outside of the gearbox housing, are connected with a rotary drum through a hub member. The transverse rotary drum connection device of the coal mining machine overcomes the problems of uneven stress, maintenance difficulty and less bearing load of a traditional rotary drum connected through flanges, and is applicable to mechanical coal mining of small and medium coal mines, especially to mining of coal seams at the bottom of a roadway.
Description
Technical field
The utility model relates to a kind of coal-winning machine transverse rollers linkage.
Background technology
Existing middle and small scale coal mine quantity accounts for more than 90% of national colliery sum, but the scale of all exploiting is less, and the exploitation tunnel is narrow, technical equipment falls behind, the colliery that has even also adopt pneumatic pick to carry out the man-made recovery, and its coal mining efficient is lower, working environment is more abominable, and personal security more is difficult to guarantee; Then feeling simply helpless especially in coal seam, bottom surface for exploitation high inclination-angle tunnel structure, causes the serious waste of a large amount of coal resources, becomes a great problem of implementing in resource-conserving and the coal resources exploitation protection strategy.
Part is used mechanical coal mining in the existing middle and small scale coal mine, the type of its use mainly is cutting coal machine, transverse rollers coal-winning machine, wherein the production efficiency of transverse rollers coal-winning machine can be exploited bottom coal seam, tunnel than the height of other type, is applied in medium and small colliery easily; But the cylinder of existing transverse rollers coal-winning machine adopts the flange syndeton more, this flange syndeton can't adapt to abominable coal work environment, not only increased cylinder impact load in the course of the work, and the load change scope is bigger, cause flange to damage the cylinder discontinuity easily; In addition, flange is installed in the cylinder inboard, changes and safeguards comparatively difficulty, has limited the expansion of transverse rollers coal-winning machine and has used.
Summary of the invention
At above-mentioned situation, the purpose of this utility model is to provide a kind of coal-winning machine transverse rollers linkage, and it is both simple in structure, practical; Be convenient for changing again, safeguard; Can also carry shock loading and on a large scale load change and work safer, reliable, production efficiency is higher, is easy to apply.
To achieve these goals, a kind of coal-winning machine transverse rollers linkage, power transmission shaft warp beam sleeve, bearing and gear-box end cap crosswise fixed are in the casing of rocker gear case, and casing intermediate solid drive shaft middle part connects travelling gear through keyway, connect cylinder through hub unit on the power transmission shaft of the outer both sides of casing.
In order to realize the full section exploitation of girdle and structure, effect optimization, its further step is:
Described power transmission shaft middle part is provided with the location shaft shoulder.
Described power transmission shaft both ends are provided with plane of orientation.
Described hub unit comprises spill end cap and the lock nut that connects power transmission shaft.
A kind of coal-winning machine transverse rollers linkage, it adopts power transmission shaft warp beam sleeve, bearing and gear-box end cap crosswise fixed in the casing of rocker gear case, casing intermediate solid drive shaft middle part connects travelling gear through keyway, connects the straight integrated technique scheme of cylinder on the power transmission shaft of the outer both sides of casing through hub unit; Overcome conventional rollers and adopted flange to connect, caused installing discontinuity, maintenance difficult, a bearing load difficult problem very little.
The beneficial effect that the utility model produces compared to existing technology:
(I) the utility model adopts the integrated power transmission shaft scheme of straight, makes the power transmission structure of cylinder simpler, compact, is convenient to installation, maintenance;
(II) the utility model adopts the integrated power transmission shaft scheme of straight, causes the inefficacy of retaining element in the time of effectively reducing the cylinder coal mining because of mechanical shock, has improved the body anti-seismic performance, has increased the application life of equipment;
(III) the utility model adopts the integrated power transmission shaft scheme of straight, and two cylinders are stressed more even about making;
(IV) the utility model adopts at power transmission shaft and sets the transmission of power connectivity scenario that bit plane adds interference fit, connects than the conventional flange disc type to have higher intensity and stability, can bear bigger load;
(V) the utility model is simple in structure, compact, practical, and cylinder is changed quick, and is easy to maintenance, can carry big load and work safelyr, reliable, and production efficiency is higher, and long service life is easy to apply, and market prospects are good.
The utility model is fit to the mechanical coal mining of middle and small scale coal mine, is particularly suitable for the exploitation in bottom coal seam, tunnel.
Below in conjunction with drawings and Examples the utility model is described in further detail.
