Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Shown in Fig. 1-8, first specific embodiment of damping sealed type gear-box of the present utility model, comprise gear upper box 1, gear lower box 2 and the motor shaft eckband 3 and the seize eckband 2 that are arranged on described box inside, be connected with small end fitting seat 10 by big end fitting seat 9 between gear upper box 1 and the gear lower box 2, be provided with axle-hang box 01 in the described gear-box seize eckband, be provided with sealing gasket 02 between the seize eckband position of described gear-box and the described axle-hang box, described sealing gasket middle part is to being outside equipped with bump, described bump cross section is a swallow-tail form, the seize eckband position of described gear-box is provided with and the suitable dovetail groove of described sealing gasket bump shape, and described sealing gasket bump is bumped in the dovetail groove at described gear-box eckband position.
Above-mentioned structure, because of model is SS3, SS 3B, SS4, SS4 changes, SS4B, the gear-box of SS6B is subjected to the internal structure spatial constraints, can't be by labyrinth seal be installed, therefore, the concrete structure of taking to improve sealing gasket for the gear-box of above-mentioned model reaches sealing effect, the bump at described sealing gasket middle part is bumped in the dovetail groove at gear-box seize eckband position, sealing gasket can displacement not be scurried out with the mutually frequent play of traction motor and axle-hang box and gear shaft, avoided in installation process by squeeze crack or moved axially the problem that causes revealing with casing taking place, sealing effect is better.
As second specific embodiment of the present utility model, described casing is provided with the last fitting seat 11 that is used to install motor; Wherein, the described fitting seat of going up is located in the other ends in the spiral shell seat board 21 by an end and is located at the steel bushing 25 in the spiral shell seat board outside and is arranged on the locking nut 22 that steel bushing wears end and constitute, be equipped with on the described steel bushing and have boss cross section L-shaped elastic sleeve 24 and cushion 23, described elastic sleeve projection section is arranged between spiral shell seat board outside steel bushing outboard end and the spiral shell seat board, remaining part is arranged between spiral shell seat board inwall and the steel bushing outer wall, and cushion is arranged between spiral shell seat board inboard and the described locking nut.
As the 3rd specific embodiment of the present utility model, described casing is provided with the following fitting seat 6 that is used to install axle suspension bearing box; Wherein, described fitting seat down connects spiral shell seat top board 31 by periphery by bolt 36, spiral shell seat base plate 35 and the installation spiral shell seat 33 that is arranged in the described spiral shell seat top board constitute, described spiral shell seat base plate and spiral shell seat top board are respectively arranged with center hole, be arranged on center hole on the described spiral shell seat top board by last, following two sections formations, wherein the epimere aperture is less than the hypomere aperture, form a step, described spiral shell seat lower end is to being outside equipped with diameter and the suitable boss of described spiral shell seat top board hypomere pore size, be provided with elastic sleeve 32 between described boss and the step, be provided with cushion 34 in the center hole of described spiral shell seat base plate.
