Detailed Description

The following describes embodiments of the present invention in detail with reference to fig. 1 to 2.

Lubricated drainage structure of bearing in reduction gear, its characterized in that: including seting up the oil trap 2 in the main casing body 1 of reduction gear, seting up in the procapsid 3 of reduction gear and with the oil trap 2 butt joint connect oil groove 4 and set up in the procapsid 3 UNICOM connect the drainage 6 of oil groove 4 and bearing mounting hole 5, oil trap 2 be located the one-level driven gear 7 side of reduction gear, collect the fluid that splashes when one-level driven gear 7 rotates to with fluid leading-in to connect in the oil groove 4.

Above lubricated drainage structure of bearing in the reduction gear, set up oil trap 2 in the main casing body 1, set up in the procapsid 3 and connect oil groove 4 and drainage way 6, oil trap 2 is located one-level driven gear 7 side, one-level driven gear 7 rotates and drives fluid and splash, oil trap 2 collects the fluid that splashes, and lead fluid to connect in the oil groove 4, connect fluid in the oil groove 4 in drainage way 6 drainage to bearing mounting hole 5, realize lubricating oil drainage in the bearing position that splashes, fully lubricate the bearing, prevent bearing high temperature burn, prolong its life.

Wherein, oil trap 2 and main casing body 1 integrated into one piece, be located the oblique top of one-level driven gear 7, oil liquid collection mouth 21 is seted up to the bottom of oil trap 2, oil liquid collection mouth 21 is close to one-level driven gear 7, oil trap 2 slopes forward, the height of front end is minimum. Oil trap 2 integrated into one piece when main casing body 1 shaping, need not in addition processing, the latter half of one-level driven gear 7 soaks in fluid, one-level driven gear 7 can drive fluid upwards to splash when rotating, the fluid that splashes gets into in oil trap 2 from fluid collection mouth 21, oil trap 2 slopes forward, the height of front end is minimum, can lead fluid to connect in oil groove 4 in, 7 rotational speeds of one-level driven gear are very high, can constantly get into fluid in the fluid collection mouth 21, fluid can not flow out, oil trap 7 constantly collects fluid, and lead to connect in the oil groove 4, flow into to connect in oil groove 4 fluid through 6 drainage to bearing mounting hole 5 of drainage way.

Wherein, the oil collecting groove 2 is in a forward flaring shape, and the cross section of the front end is the largest.
