Embodiment
plane table thermoconductivity meter in this example as shown in Figure 1.This retarder comprises the shell be made up of ring gear 11 and end cap 10, and end cap 10 is connected with ring gear 11 through screw.The shape of ring gear 11 is that the open circular cup-shaped member of the other end is closed in one end, and closed end is the output terminal of retarder, is provided with the flange plate be connected with load, and the inwall of ring gear 11 is provided with annular internal tooth.
be provided with planet carrier 8 in shell, the center hole on endoporus respectively through exporting bearing 6 and ring gear 11 output terminal of the coupling shaft at planet carrier 8 two ends and end cap 10 is rotationally connected.Be provided with two input shaft bearing 12 in the endoporus of planet carrier 8, the inner ring of input shaft bearing 12 is connected with the axis of rotation at sun gear 1 two ends.Planet carrier 8 is provided with planet wheel 9, and the planet axis 5 at planet wheel 9 center is slidably connected through sliding bearing 4 and planet carrier 8; Planet wheel 9 is connected with a joggle with ring gear 11 and sun gear 1.
in this example, the lubricating structure at planet wheel place is as shown in 2 ~ 5, and planet wheel 9 both ends of the surface are provided with oil guide slot 13, and oil guide slot 13 extends to endoporus from planet wheel 9 tooth top cylindrical, and two oil guide slot 13 are symmetrically formed 30 ± 20 ° of angles with the center line 15 of planet wheel.The planet axis 5 at planet wheel 9 center, planet axis 5 is provided with oil storage tank 14, oil storage tank 14 communicates with the oil guide slot 13 of planet wheel 9 both ends of the surface, the lubrication channel oil guide slot 13 of planet wheel 9 both ends of the surface linked together between formation planet axis 5 and sliding bearing 4 by oil storage tank 14.Described oil storage tank 14 to be actually in planet axis 5 flat horizontal surface or straight line oil groove vertically, therefore when installing planet axis 5, oil storage tank 14 in planet axis 5 must be aimed at the oil guide slot 13 of planet wheel 9 both ends of the surface, and adopt interference Placement between planet wheel 9 and planet axis 5, misplace to prevent from producing between oil storage tank 14 and oil guide slot 13 in rotation process.
the lubrication principle of this example as shown in Figure 6.When planet wheel 9 be clockwise to oil guide slot 13 be positioned at non-coincidence region (Tian You district 15) with planet carrier 8 of planet wheel 9 time, the grease around planet wheel 9 flows into oil guide slot 13 automatically.When planet wheel 9 continues to rotate to planet wheel 9 and planet carrier 8 overlapping region (oil suction district 16), grease in oil guide slot 13 is under the effect of relatively-stationary planet carrier 8 and oil guide slot 13, do centripetal screwfeed campaign, grease flows along oil guide slot A to central suction, realizes pump functional oil.Oil guide slot 13 circulates repeatedly in Tian You district 15 and oil suction district 16, and grease is sucked continuously to be filled in lubrication channel.On the contrary, when planet wheel 9 rotates counterclockwise, grease is sucked continuously along oil guide slot 13 and is filled in lubrication channel.Rotation with planet axis 5 makes sliding bearing 4 endoporus cylndrical surface be lubricated fully.
the sealing configuration of this example mainly contains following two places: a place is at sun gear place.As shown in Figure 7.Sun gear 1 is provided with the gear teeth engaged with planet wheel 9, when processing the gear teeth, on sun gear 1, inevitably leave gear hobbing allows tool marks 17, gear hobbing allow tool marks 17 place directly can not install rubber seal, and therefore this example allows tool marks 17 place arrange annular oil seal cover 2 in the gear hobbing of sun gear 1.The length of annular oil seal cover 2 covers gear hobbing completely allows tool marks region.Annular oil seal cover 2 forms a rigid body with sun gear 1 interference fit.Realize sealing by reinforced seal 3 between the cylindrical of annular oil seal cover 2 and the endoporus of planet carrier 8, reinforced seal 3 for sectional shape be the loop configuration of U-shaped, reinforced seal 3 is positioned at annular oil seal and overlaps 2 cylindricals, fits inside U-shaped bottom surface and input shaft bearing 12.
another place is inside output bearing 6.As shown in Figure 8, exporting inside bearing 6 and be provided with oil baffle 7 between planet carrier 8.By planet carrier 8 and the interference fit exported between bearing 6 inner ring, oil baffle 7 is fixed.Oil baffle 7 endoporus and bearing outer ring keep small―gap suture to coordinate, and the gap keeping less between oil baffle 7 lower end surface and end cap 10 forms maze spatial.After retarder long time running, temperature rising casing confined space internal air pressure also raises, and has certain mobility after lubricant grease dilution.But due to the existence of oil baffle 7, make grease not hold outside 6 inflow retarders by output shaft, realize the mechanical sealing exporting bearing 6.
