    The invention relates to a change-speed transmission with a bevel and spur gear mechanism for driving the belt conveyor in above-ground coal mining. The invention relates to the constructional solution for the two-part case of the bevel and spur gear mechanism and the manner of mounting the rolling bearings of the driving bevel gear in the transmission case. It is the object of the invention to make a considerable improvement in the lubrication of the three bearings mentioned and to simplify the structure and manufacture of the transmission case. The essence of the invention of the bevel and spur gear mechanism with shafts in the horizontal position which are supported in a two-part case of the transmission, which is split in the axis of the shafts and consists of a lower part and a cover of the transmission case, lies in the constructional solution for the case of the transmission, in which the flanges of the lower part of the transmission for supporting the rolling bearings of the driving bevel gear are formed in the interior of the lower part and of the cover of the transmission casing. In this arrangement, the driving bevel gear is supported with its rolling bearings in the said flanges of the lower part of the transmission case such that, on one side, it is supported next to the hub in the flange, radially in a radial rolling bearing and axially in two axial barrel-type rolling bearings and, on its other side, is supported at the entry journal in the inner flange, radially in the radial rolling bearing.

    The invention relates to a constructive solution of a two-half gear case with a bevel and a spur gear and a method for installing the bevel rolling bearings in the gear body.
    A gearbox with bevel and cylindrical gears and horizontally arranged shafts, sized 1, is known in the two-half gear case with a connector along the axis of the gear, in which a freely mounted bevel gear is installed on its hub radially in one radial bearing in the flange inner partition of the pallet of the gearbox, and at the entrance axle is installed axially in two axial bearings and radially in one radial bearing in B1 of the iiapy flange of the K case wall and programs (Aug. St. USSR № 401845, class, F 16 N 57/04. 1971 ;,
    With such an installation of a conical i.user, a closed space is created, g; which, through the corresponding blocks, drilled into the outer flange of the outer wall of the gearbox housing or vtu:; undersize cushion, oil is supplied for rolling stock. Oil is fed into these holes or channels from the oil of the side pockets, which are cast or welded to the inside of the outer wall of the gearbox housing. The gears floating in the oil bath, which is located in the bottom of the crankcase, disassemble the oil and thereby lubricate everything (; -; gal1, the box rolling bearings, and the oil flowing from the gearbox housing step to the aforementioned oils; St.;: 1 casting pockets, through distributing hole holes drilled in the flange of the outer wall of Kopiivc; ь ..:. | robots of gears or bearing bushings, lubricate; those three tips indicate; iodine and rolls that are displaced in w.yum iut closed npocTpancriie. method of lubrication of gears and luvunniiiuuiot: bypass schiys without oily iasssa

After such a design of the pallet 11, its flanges 111, 112 for fitting the rolling bearings 4 of the bevel gear 21 and the cover 12, all the rolling bearings 4 become an integral part of the internal arrangement of the gear 13 and can be spread out the oil from the bevel gear 22 and the spur gear 31, which float in the oil bath 6 formed in the pan 11. The upper hollow space 1113, cast in the top, is filled with oil spread inside the gearbox 13 It flange half 1112 of the hole 1114 which oil flows between the axial barrel rolling bearings 42.
    It is possible to group rolling bearings 4 of bevel gear 21 in a different number of flanges 111, 112 than indicated in the drawing, however, all rolling bearings 4 are necessarily part of the internal structure of the gear box 13.
