Abstract
The utility model discloses a seal structure of outboard bearing dustproof and waterproof cylinder is connected quiet floating seal ring through the flange with the bearing frame, move superficial and be connected with an adoption interference, wherein moves superficial and a superficial quiet formation labyrinth sealing, and floating oil seal is equipped with to inside, when the leader of the government rotates, moves the rotation of superficial drive floating oil seal one end, moving and float sealing a seat hole and open and have the ring channel, O type circle III is installed to the ring channel, becomes static sealing with the axiform, the quiet seat hole that float to seal is opened and is had the ring channel, and felt ring is installed to the ring channel, and felt ring seals a seat excircle and forms a labyrinth sealing with moving to float. The utility model provides the high life of cylinder has reduced the disability rate of spare part, has solved effectively that the cylinder sealedly became invalid easily, sealed difficult problem.
Description
Technical field
This utility model relates to belt conveyer roller, particularly relates to the sealing structure of a kind of outboard bearing dustproof and waterproof cylinder.
Background technology
Strong belt machine cylinder is the vitals in belt conveyor systems and ingredient.Aircraft tail cylinder, in transportation, is in the cylinder of ribbon conveyer lower end, and operating mode site environment is extremely complex, is immersed in the most for a long time in the mixture such as water coal slime, and environment is extremely severe, therefore it is required that cylinder has preferable sealing property to water, coal slime, dust etc..And current existing cylinder its to seal structure the most relatively simple, only at rotary shaft, play sealing function by outside framework oil seal, after working long hours, seal failure directly contributes cylinder support bearing unstable wear and causes cylinder normally to work.
Summary of the invention
The purpose of this utility model is to provide the sealing structure of a kind of outboard bearing dustproof and waterproof cylinder.This utility model have employed the combination sealing of float grease seal and various ways, efficiently solves cylinder and seals easily inefficacy, the problem of difficult sealing, reduces the scrappage of parts, improve the service life of cylinder.
The technical solution of the utility model is: the sealing structure of a kind of outboard bearing dustproof and waterproof cylinder, it is characterized in that being connected with bearing block by quiet floating sealing base by flange, dynamic floating sealing base uses interference to be connected with axle, wherein move floating sealing base and form labyrinth seal with quiet floating sealing base, move between floating sealing base and quiet floating sealing base equipped with float grease seal, when axle rotates, dynamic floating sealing base drives float grease seal one end to rotate；Dynamic floating sealing base endoporus has cannelure, and cannelure is provided with O III, forms static sealing with axle；Quiet floating sealing base endoporus has cannelure, and cannelure is provided with felt collar, and felt collar forms labyrinth seal with dynamic floating sealing base cylindrical.
Bearing block uses unsymmetric form, is provided with fuel feed hole, and the lubrication for float grease seal provides safeguard.
This utility model is that outboard bearing dustproof and waterproof cylinder provides one and seals structure reliably, by using the combination sealings such as float grease seal, labyrinth seal, static sealing, it is effectively increased external cylinder sealing effectiveness and service life, reduce the scrappage of parts, it is ensured that the normal use of delivered downhole mechanism.
Accompanying drawing explanation
Fig. 1 is this utility model entirety sectional arrangement drawing.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further illustrated.
As shown in Figure 1 and Figure 2, this utility model includes reel 1, support 2, axle 3, key 4, bearing block 5, end cap 6, bearing 7, shaft block ring 8, O I9, bolt 10, quiet floating sealing base 11, O II12, felt collar 13, float grease seal 14, dynamic floating sealing base 15, O III16.Wherein being connected with bearing block 5 by quiet floating sealing base by flange, dynamic floating sealing base 15 uses interference to be connected with axle 3, equipped with float grease seal 14 between dynamic and static floating sealing base.The most quiet floating sealing base 11, bearing block 5 are connected by bolt 10, are fixed on base.
When axle 3 rotates, dynamic floating sealing base 15 drives float grease seal 14 one end to rotate, and plays sealing function；Quiet floating sealing base 11 endoporus has cannelure, and cannelure is provided with felt collar 13, is formed with dynamic floating sealing base 15 cylindrical and seals；Dynamic floating sealing base 15 endoporus has cannelure, and cannelure is provided with O III16, and coordinates with axle 3, plays static seal effect.
Dynamic floating sealing base 15 and axle 3 interference fit, and play static sealing effect by O III16.Change the version of tradition rotatory sealing, it is ensured that effective sealing effectiveness.
Dynamic floating sealing base 15 and quiet floating sealing base 11 form labyrinth seal, internal and equipped with float grease seal 14.
Bearing block 5 uses unsymmetric form, is provided with fuel feed hole, and the lubrication for float grease seal 14 provides safeguard.
In cylinder rotation process, rotation is transmitted successively by reel, support, axle, dynamic floating sealing base, quiet floating sealing base and bearing block are fixed on base, produce one with dynamic floating sealing base to relatively rotate, and play sealing function by float grease seal and multiple seal combination, improve the problem that conventional rollers axial-rotation seals difference.
Embodiment described above is a kind of preferred version of the present utility model, and this utility model is not made any pro forma restriction, also has other variant and remodeling on the premise of without departing from the technical scheme described in claim.
