Model utility content
According to above-mentioned actual demand, the utility model provides a kind of transfer case body that movable axis is installed, and its support strength and dust-proof effect can meet actual operation requirements.
For addressing the above problem, technical solution adopted in the utility model is as follows:
A kind of transfer case body that movable axis is installed, comprise casing, described casing is provided with movable axis mounting hole, in described movable axis mounting hole, be provided with dustproof seal ring, described dustproof seal ring has edge assembly department and center hole, described center hole is used for being sleeved on movable axis, and installation position, described edge is in described movable axis mounting hole or be positioned at described box inside, and described edge assembly department diameter is more than or equal to the internal diameter of described movable axis mounting hole.
As the improvement of technique scheme, described edge assembly department diameter equals the internal diameter of described movable axis mounting hole, installation position, described edge is in described movable axis mounting hole, and described dustproof seal ring has the flexible structure that its center hole is moved to any direction.
As the improvement of technique scheme, described dustproof seal ring is that nitrile rubber is made, and described dustproof seal ring cross section is snakelike.
As the improvement of technique scheme, the described edge assembly department of described dustproof seal ring is fixedly arranged in described movable axis mounting hole by grommet.
As the improvement of technique scheme, described casing comprises nowel and upper cover, and described upper cover is provided with access cover.
As the improvement of technique scheme, described nowel bottom is provided with fitting seat, described nowel sidewall is vertically provided with reinforces rib muscle, and described reinforcing rib muscle is that wedge shape and width increase from top to bottom successively, and the bottom of described reinforcing rib muscle is fixedly arranged on described fitting seat.
Compared with prior art, implementation result of the present utility model is as follows for the utility model:
The transfer case body that movable axis is installed described in the utility model, moves the axial location that casing can adaptive act axle, and in the process moving at movable axis, remains the sealing of movable axis mounting hole, thereby realize dust-proof effect; And the concrete structure of further preferred dustproof seal ring 2, makes it to have better dust-proof effect and installation, replacing convenience.And improve the mechanical support performance of casing, made it to have better mechanical strength and steadiness is installed.

Fig. 1 is the transfer case body one side structure schematic diagram that movable axis is installed described in the utility model;
Fig. 2 is the transfer case body another side structural representation that movable axis is installed described in the utility model;
Fig. 3 is the dustproof seal ring structural representation of the transfer case body that movable axis is installed described in the utility model;
Fig. 4 is the dustproof seal ring cross section structure schematic diagram of the transfer case body that movable axis is installed described in the utility model.
Embodiment
Content of the present utility model is described below in conjunction with specific embodiments.
As shown in Figures 1 to 4, be the transfer case body structure schematic diagram that movable axis is installed described in the utility model.The transfer case body that movable axis is installed described in the utility model, comprise: comprise casing: it is characterized in that, described casing is provided with movable axis mounting hole 1, in described movable axis mounting hole 1, be provided with dustproof seal ring 2, described dustproof seal ring 2 has edge assembly department 3 and center hole 4, described center hole 4 is for being sleeved on movable axis, described edge assembly department 3 is positioned at described movable axis mounting hole 1 or is positioned at described box inside, and described edge assembly department 3 diameters are more than or equal to the internal diameter of described movable axis mounting hole 1.Described structure moves the axial location that casing can adaptive act axle, and in the process moving at movable axis, remains the sealing of movable axis mounting hole 1, thereby realizes dust-proof effect.
Further with improvement, described edge assembly department 3 diameters equal the internal diameter of described movable axis mounting hole 1, and described edge assembly department 3 is positioned at described movable axis mounting hole 1, and described dustproof seal ring 2 has the flexible structure that its center hole 4 is moved to any direction.Described edge assembly department 3 is positioned at described box inside, and described edge assembly department 3 diameters are greater than the internal diameter of described movable axis mounting hole 1 also can realize dust-proof effect, but the gap between dustproof seal ring 2 and box inside can make a small amount of dust enter, therefore dust-proof effect equals the internal diameter of described movable axis mounting hole 1 not as described edge assembly department 3 diameters, and described edge assembly department 3 is positioned at the good of described movable axis mounting hole 1.Particularly, described dustproof seal ring 2 is made for nitrile rubber, and described dustproof seal ring 2 cross sections are snakelike.Described structure is described dustproof seal ring 2, and to have the one making in flexible structure that its center hole 4 moves to any direction specifically preferred.Specifically preferably, the described edge assembly department 3 of described dustproof seal ring 2 is fixedly arranged in described movable axis mounting hole 1 by grommet 5.Described structure is convenient to installation and the replacing of described dustproof seal ring 2.
