Abstract
The utility model discloses a transaxle wheel limit seal structure, including box -shaped sealing member (3) of pressure equipment in hub (1), the inner ring and installation tang (2) the cooperation of box -shaped sealing member (3), the outside of hub (1) is close to box -shaped sealing member (3) and locates to set up the V type groove (4) that a plurality of opening angle scopes are 10 degrees to 20 degrees, constitutes mazy seal structure. This transaxle wheel limit seal structure regards as main sealed means and hub rotatory together the box -shaped sealing member, and it is sealed to form the confined, and the V type groove that the hub outside was seted up constitutes the labyrinth seal structure, makes the outside dirty V type inslot of at first piling up, effectual separation the erosion to the box -shaped sealing member of outside greasy dirt, dust and water, guaranteed sealed effect, showing the life who has increased the box -shaped sealing member.
Description
Technical field
The utility model relates to a kind of sealing configuration, specifically a kind of drive axle wheel edge sealing configuration.
Background technique
Traditional drive axle wheel edge sealing configuration for be provided with lip-type packing on seam, but because its structure is simple, working life is shorter, leakage of oil event happens occasionally, and cartridge seal part replaces lip-type packing gradually because its long service life, functional reliability are higher.But the work condition environment of engineering machinery drive axle wheel edge is more severe, the sealing configuration that seam installs boxlike Sealing usually affects sealing effect because of a large amount of greasy dirts and dust, and the working life of cartridge seal part is also shortened greatly.
Model utility content
For above-mentioned prior art Problems existing, the utility model provides a kind of drive axle wheel edge sealing configuration, effectively can intercept outside greasy dirt and dust to the pollution damage of cartridge seal part, significantly increases the working life of cartridge seal part.
To achieve these goals, this drive axle wheel edge sealing configuration comprises the cartridge seal part be fitted in wheel hub;
The inner ring of described cartridge seal part coordinates with installation seam;
The outside of described wheel hub, offers near cartridge seal part place the V-type groove that multiple opening angle scope is 10 degree to 20 degree, forms mazy sealing configuration.
Further, described V-type groove offers three side by side.
Further, the opening angle of described V-type groove is 10 degree.
Compared with prior art, cartridge seal part rotates together with wheel hub as main seal means by this drive axle wheel edge sealing configuration, form the sealing closed, the V-type groove offered outside wheel hub forms labyrinth seal structure, make outside to be dirtyly first stacked in V-type groove, effective outside greasy dirt, dust and the water of intercepting, to the erosion of cartridge seal part, ensure that sealing effect, significantly increases the working life of cartridge seal part.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1, wheel hub, 2, seam is installed, 3, cartridge seal part, 4, V-type groove.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, this drive axle wheel edge sealing configuration comprises the cartridge seal part 3 be fitted in wheel hub 1;
The inner ring of described cartridge seal part 3 coordinates with installation seam 2;
The outside of described wheel hub 1, offers near cartridge seal part 3 place the V-type groove 4 that multiple opening angle scope is 10 degree to 20 degree, forms mazy sealing configuration.
Press-fit in this drive axle wheel edge sealing configuration into wheel hub 1 cartridge seal part 3 with installation seam 2 together with as main seal means, prevent the generation of drive axle wheel edge leakage of oil event, multiple V-type groove 4 forms labyrinth structure, effectively can intercept outside greasy dirt, dust to the impact of wheel limit sealing, add the working life of cartridge seal part 3.
Further, described V-type groove 4 offers three side by side.Offer the sealing effect that three V-type grooves 4 effectively can realize this drive axle wheel edge sealing configuration, the concrete quantity of certain V-type groove 4 also can increase according to concrete structure and actual demand or reduce.
Further, the opening angle of described V-type groove 4 is 10 degree.Namely the opening angle of 10 degree can ensure that V-type groove 4 effectively can intercept outside greasy dirt, dust and water to the erosion of cartridge seal part, ensure that sealing effect.
In sum, cartridge seal part rotates together with wheel hub as main seal means by this drive axle wheel edge sealing configuration, form the sealing closed, the V-type groove offered outside wheel hub forms labyrinth seal structure, make outside to be dirtyly first stacked in V-type groove, effective outside greasy dirt, dust and the water of intercepting, to the erosion of cartridge seal part, ensure that sealing effect, significantly increases the working life of cartridge seal part.
