Abstract
A dust ring for high-density dust occasion comprises a support framework and an elastic sealing member, wherein the support framework comprises a longitudinal outer framework section, a horizontal transitional framework section and an inclined inner framework section; the longitudinal outer framework section and the inclined inner framework section are connected into an integral structure by the horizontal transitional framework section; and the surface at the connecting position of the horizontal transitional framework section and the inclined inner framework section are fixedly provided with at least two horizontal dust lips. In the utility model, the dust ring is designed with two dust lips; the thickness of the dust lips is thinner; the interference is larger; and after being assembled with a shaft, the dust lips have larger-scale contact zones, the dustproof effect is good, and the friction torque is also lower.
Description
Technical field
The utility model relates to a kind of dust ring, especially relates to a kind of high density dust occasion dust ring.
Background technique
Sandstone shredder, agricultural products shredder etc. in use can cause higher dust density.Therefore at the axle and the position that bearing rotates of sandstone shredder, agricultural products shredder etc., need to install sealed product and reveal, keep the good lubrication of bearing to prevent the lubricating grease in the bearing; To prevent that also the larger particles dusts of pulverizing such as sandstone from entering bearing inside, cause damage of bearings.Common dust ring is bad to larger particles Dust guard effects such as sandstones, reach good sealing effect, need dust excluder lips that bigger magnitude of interference is arranged, but this can strengthen the friction to axle, brings bigger rotation torque.
The model utility content
The technical problems to be solved in the utility model provides a kind of high density dust occasion dust ring; This dust ring has designed two dust excluder lips, the thinner thickness of dust excluder lips design, and magnitude of interference is bigger, has the larger area contact zones after assembling with axle, good dustproof effect, friction torque is also lower.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: it comprises support frame and elastic sealed body; Described support frame comprises vertically outer skeleton segment, cross transition skeleton segment and inclination inner frame section, and described vertical outer skeleton segment and inclination inner frame section are by the cross transition skeleton segment structure that is connected to form one; The surface of described cross transition skeleton segment and inclination inner frame section joint is installed with at least two dust excluder lips of level.
Further, described dust excluder lips length is 4-8 centimetre, forms accumulator between two lips; Accumulator injected lubricating grease in the past, the friction when reducing the axle rotation, the wearing and tearing of protection lip.
Further, described dust excluder lips is a rectangular, and thickness is 0.5-1 centimetre; Matching allowance design with axle.
Further, the described vertically outer surface of outer skeleton segment is provided with black sealing enamelled coating.
The utlity model has following beneficial effect:
1) skeleton that leaks outside is done seal, with the housing interference fit, does not hang rubber, saves rubber material.
2) dust excluder lips is designed to thin rectangular, and is bigger than common dust ring with the matching allowance design of axle, good dustproof effect, and friction and rotation torque are little.
3) dust excluder lips is designed to 2～3, improves sealing effect
4) the dust excluder lips design is longer, forms accumulator between two lips, can annotate lubricating grease, the friction when reducing the axle rotation, the wearing and tearing of protection sealing lip.
In a word, the utility model has improved sealing reliability, has prolonged the working life of Sealing and axle and bearing.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail
Fig. 1 is the utility model structural representation;
Fig. 2 is a user mode reference drawing of the present utility model.
Embodiment
Participate in shown in Fig. 1,2, the utility model comprises support frame 1 and elastic sealed body 2; Described support frame 1 comprises vertically outer skeleton segment 11, cross transition skeleton segment 12 and inclination inner frame section 13, and described vertically outer skeleton segment 11 and inclination inner frame section 13 are by cross transition skeleton segment 12 structure that is connected to form one; Described cross transition skeleton segment 12 has horizontally extending two dust excluder lips 21,22 with the surface sulfuration one of inclination inner frame section 13 joints;
Described dust excluder lips length is 4-8 centimetre, forms accumulator 23 between two dust excluder lips 21,22; Accumulator 23 injected lubricating grease 24 in the past, the friction when reducing the axle rotation, the wearing and tearing of protection lip;
Described dust excluder lips 21,22 is a rectangular, and thickness is 0.5-1 centimetre; Matching allowance design with axle;
The described vertically outer surface of outer skeleton segment 11 is provided with black sealing enamelled coating 111.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here can't give exhaustive to all mode of executions.Everyly belong to the row that conspicuous variation that the technical solution of the utility model extends out or change still are in protection domain of the present utility model.
