Detailed description of the invention
Below in conjunction with accompanying drawing 1-4, the present invention is described in detail.
According to a kind of sewage disposal tank arrangement of the present invention, comprise the tank body 1 of setting, described tank body 1 has the upper tank body and lower tank that are provided separately, and upper tank body and lower tank are fixedly connected with tank body fixed mount 12 respectively, thus can realize the support that is separated from each other, from a distance thus form maintenance window 2, the external peripheral surface of upper tank body and lower tank is provided with outside thread, and coupling bush 14 can cover described maintenance window place thus by airtight for described tank body 1 by screw thread fit for upper tank body and lower tank, the external peripheral surface of described coupling bush 14 is provided with upper ring gear 22 separately and lower ring gear 23, the left driving shaft 7 and right driving axle 6 that vertically extend is respectively arranged with at the left and right sides place of described tank body 1, described left driving shaft 7 is relative in the diametric(al) of described tank body 1 with right driving axle 6, each in described left driving shaft 7 and right driving axle 6 is all installed in rotation on described tank body fixed mount 12, and lower end is connected with described tank body fixed mount 12 by lower bearing, left, right sprocket wheel 5, 4 are connected with Power Drive Unit by chain 13, described left driving shaft 7 and right driving axle 6 are on a close described left side, right sprocket wheel 5, 4 positions are connected with tank body fixed mount 12 respectively by head bearing, and described left driving shaft 7 and right driving axle 6 are disposed with upper limit portion 8 and lower limit portion 9 between corresponding head bearing and lower bearing, spline slide portion 27 is provided with between upper limit portion 8 and lower limit portion 9, described spline slide portion each in described left driving shaft 7 and right driving axle 6 all can be combined with Double-gear sleeve member 24 slidably, described Double-gear sleeve member 24 is fixing on rotating with corresponding axle drive shaft by spline fitted, two ends up and down each in two described Double-gear sleeve members 24 arrange cog 10 and lower gear 11 respectively regularly, described cog 10 and lower gear 11 engage with described upper ring gear 22 and lower ring gear 23 respectively, and two described Double-gear sleeve members 24 cog 10 in the diametric(al) of described tank body 1 relatively, the lower gear 10 of two described Double-gear sleeve members 24 is also relative in the diametric(al) of described tank body 1
Described coupling bush 14 is fixedly installed upper limit ring 15, middle spacing ring 16 and lower limit ring 17 from top to bottom successively, middle spacing ring 16 is between described upper ring gear 22 and lower ring gear 23, upper limit ring 15 is positioned on the upside of upper ring gear 22, and lower limit ring 17 is positioned on the downside of described lower ring gear 23; At described upper limit ring 15 and cog between 10, cogging between 10 and middle spacing ring 16, between middle spacing ring 16 and lower gear 11, between lower gear 11 and lower limit ring 17 is respectively arranged with the first elastomeric ring 18, second elastomeric ring 19, the 3rd elastomeric ring 20 and the 4th elastomeric ring 21 successively
Wherein, between the negative thread tooth of described coupling bush 14 and described tank body 1 outside thread tooth, there is longitudinal tolerance clearance, described sewage disposal tank arrangement also comprises zigzag tread patterns frame 3, zigzag tread patterns frame 3 has two actuating arms, and described two actuating arms are connected with described two Double-gear sleeve members 24 respectively by bogie thrust baring 25.
