Problems solved by technology
[0005] Adopting the gear cover of the deceleration device for industrial and mining electric locomotives of the present invention effectively solves the problem that the traction motor rotates at a high speed and causes grease splashing to cause pollution inside the locomotive and the rails in the roadway, reduces the loss of grease, and prevents debris from falling on the gears. The gears can keep the state of grease lubrication for a long time, prolonging the life of the gears

Embodiment Construction
[0009] The gear cover of the deceleration device of industrial and mining electric locomotives includes upper and lower covers 5a, 5b matched with the cover of the pinion 3 and the large gear 4, the upper and lower covers 5a, 5b are interlocked to form the gear cover 5, the gear cover Have pinion shaft hole 6 on the front side of 5, have axle hole 7 oppositely on the front and back sides of gear cover body 5, be provided with the holder 8 that is fixedly connected with traction motor 1 on the front side of gear cover body 5.
[0010] Further, the fastening structure includes an upper mounting plate 9 installed on the left and right sides of the upper cover body 5a, and a lower mounting plate 10 respectively installed on the left and right sides of the lower cover body 5b. The lower mounting plate 10 is fixedly connected. In addition to the above-mentioned fastening structure, the present invention can also adopt any known fastening structure in the art, but the fastening struc...

The invention relates to a gear cover and particularly relates to a gear cover for a speed reducing device of an industrial and mining electric locomotive. The gear cover comprises an upper cover body and a lower cover body which are matched with a small gear and a large gear in a covering manner, wherein the upper cover body and the lower cover body are buckled to form a gear cover body; a small gear shaft hole is formed in the front side face of the gear cover body; axle holes are relatively formed in the two front and rear side faces of the gear cover body; the front side face of the gear cover body is provided with a fixed seat which is fixedly connected with a traction motor. With the adoption of the gear cover for the speed reducing device of the industrial and mining electric locomotive, the problem that grease splashes to pollute the inner part of the locomotive and a rail in a roadway when the traction motor rotates at a high speed is solved effectively; the loss of the grease is reduced and impurities are prevented from falling down to the gears; the gears can keep a grease lubricating state for long time so that the service life of the gears is prolonged.
Description
technical field [0001] The invention relates to a gear cover, in particular to a gear cover for a deceleration device of an industrial and mining electric locomotive. Background technique [0002] At present, the gear transmission reduction device structure of the first-stage transmission industrial and mining electric locomotive is used in domestic coal mines and tunnel construction rails (see figure 1 ) One end of the traction motor 1 slides to hold the axle (axle 2), and the output end of the traction motor 1 is equipped with a small gear 3, which meshes with the large gear 4 installed on the axle 2 to drive the axle 2 to rotate. Due to its slow continuous speed, grease lubrication is often used as the lubrication method. During operation, the grease will splash with the rotation of the gears (pinion 3 and large gear 4). If there is a gear cover, the splash of grease will cause great pollution to the interior of the locomotive and on the track, which not only causes diff...
