Abstract
The utility model discloses a combined sealing structure of a main bearing of a roller press. The combined sealing structure of the main bearing of the roller press comprises a roller shaft, a shaft sleeve, a bearing pedestal, a transparent cover, a sealing baffle and a sealing ring, wherein the roller shaft is installed on the bearing pedestal through the shaft sleeve and the bearing, the roller shaft is sleeved with the transparent cover, the transparent cover is in sealing connection with the outer end face of the bearing pedestal, a sealing loop is arranged on the contact face between the transparent cover and the shaft sleeve, an oil filling hole is formed in the transparent cover, and the oil filling hole penetrates into the contact face between the transparent cover and the shaft sleeve; the sealing baffle is arranged on the outer side of the transparent cover; the roller shaft is sleeved with the sealing ring, the sealing ring is in interference fit with the end of the shaft sleeve, the sealing ring is located on the outer side of the sealing baffle, and sealing connection is formed between the sealing ring and the transparent cover. Due to the design of a rotating oil seal and a labyrinth seal, impurities and the like are prevented from entering, and the service life of the rotating oil seal is guaranteed.
Description
Technical field
The utility model relates generally to the bearing seal structure of roll squeezer.
Background technique
Roll squeezer is due to advantages such as its energy-conservation, volume increase significantly, is widely used in the grinding of raw material, grog of cement industry, and in addition, it can also be used to the brittle materials such as grinding ore, slag, coal, industrial chemicals.
Roll squeezer is a kind of high pressure bed of material milling equipment, and its main bearing belongs to heavy-duty bearing, and working condition is mainly low speed, heavy duty, impulsive load and vibration.In the time of operation, roll squeezer main bearing working condition is severe, wherein also front and back slip and beat in frame of movable roll and bearing support thereof, when roll squeezer pressing materials, produce a large amount of fine powders, whole milling plant running environment is also very severe simultaneously, must adopt reliable sealing configuration to guarantee the works fine environment of main bearing, prevent that main bearing from causing damaging owing to entering impurity.
The two groups of lip-type packings of many employings of current roll squeezer main shaft seals structure or lip-type packing are in conjunction with the sealing configuration of the forms such as v-ring.Because sealing is in the inner side of bearing support, cannot carry out examination and maintenance in wearing and tearing or after damaging, once damage the damage that very easily causes main bearing, and replacing main bearing and inner seal must be dismantled the pipe of input on roll squeezer top, feeder, frame, speed reducer, pipeline and electric elements etc., finally hang out roller maintenance, the maintenance replacement cycle is long, main bearing is as the key components and parts of roll squeezer simultaneously, price is high, lead time is long, after damaging, direct and consequential damage is all larger, therefore must adopt a kind of reliable sealing configuration to guarantee the good running environment of main bearing.
Summary of the invention
For the defect existing in prior art and technical problem, the utility model provides a kind of combined sealing structure of roll squeezer main bearing, has overcome the shortcoming that current roll squeezer main shaft seals structural reliability is poor, part life is low.。
For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of combined sealing structure of roll squeezer main bearing, comprise roll shaft, axle sleeve, bearing support, transparent cover, sealing baffle and seal ring, described roll shaft is arranged on bearing support by axle sleeve and bearing, described transparent cover is enclosed within on roll shaft and with the exterior edge face of bearing support and is tightly connected, surface of contact between transparent cover and axle sleeve is provided with seal ring, and described transparent cover is provided with tank filler sleeve, and this tank filler sleeve connects to the surface of contact of transparent cover and axle sleeve; Described sealing baffle is located at the outside of transparent cover; Described seal ring set forms interference fit on roll shaft and with sleeve end, and seal ring is in sealing baffle outside, and and transparent cover between form and be tightly connected.
As preferably, between described transparent cover and axle sleeve, surface of contact is provided with 2 lip-type packings vertically, and is provided with spacer ring in the middle of two lip-type packings, and the hydraulic fluid port of this spacer ring is connected with the tank filler sleeve of transparent cover.
As preferably, described seal ring is boss structure, and and transparent cover between form labyrinth shape sealing.
As preferably, described seal ring is provided with v-ring, and forms rotary oil seal with sealing baffle.
As preferably, the inner ring of described sealing baffle is labyrinth structure.
Beneficial effect: with respect to prior art, the utlity model has following advantage: in rotary oil seal outside, be equipped with labyrinth seal, entering of prevention and minimizing impurity etc., guarantees the working life of rotary oil seal; The design of twice rotary oil seal and labyrinth seal, has improved the reliability of sealing greatly; When operation, roll squeezer lubrication system constantly joins lubricating grease in seal chamber by the spacer ring between oilhole and the lip-type packing of transparent cover, discharge finally by outside labyrinth seal place, both can guarantee the sealing effect of rotary oil seal, also can take away impurity in seal chamber etc., guarantee good sealing effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, transparent cover 1, O-ring seals 2, bearing support 3, oil hole 4, sealing baffle 5, lip-type packing 6, bearing 7, spacer ring 8, axle sleeve 9, roll shaft 10, seal ring 11, v-ring 12.
Embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is described in further detail.
As shown in Figure 1, a kind of combined sealing structure of roll squeezer main bearing, bearing is arranged in bearing support, and transparent cover is arranged on the exterior edge face of bearing support, forms static seal by the O-ring seals being arranged in transparent cover.Two groups of lip-type packings are installed in transparent cover, between two groups of lip-type packings, are provided with the spacer ring with hydraulic fluid port, the hydraulic fluid port of spacer ring is connected with the tank filler sleeve in transparent cover, and lip-type packing is axially being fixed by sealing baffle.Sealing baffle is bolted on the exterior edge face of transparent cover, and the inner ring of sealing baffle is labyrinth structure, and outer ring coordinates with transparent cover.Seal ring and axle sleeve are arranged on roll shaft by interference fit joint, and v-ring is arranged on seal ring, form rotary oil seal with sealing baffle.Transparent cover inner side is designed to form of grooves, and seal ring is boss structure, and both form labyrinth seal.
When roll squeezer work, lip-type packing and axle sleeve form rotary oil seal, its outside is the labyrinth seal that sealing baffle and seal ring, axle sleeve form, then outside be the rotary oil seal of v-ring and sealing baffle formation, and most external is transparent cover and seal ring formation labyrinth seal.Lubricating grease timing adds from the tank filler sleeve of transparent cover, finally discharges from the labyrinth between seal ring and transparent cover.
Roll squeezer carries out large repairs or checks, while changing main bearing, must check lip-type packing and the v-ring of bearing support inner side simultaneously, if necessary, must change in time, to guarantee the good running environment of main bearing.The utility model improves main shaft seals reliability of structure greatly, has guaranteed the working life of lip-type packing, v-ring and main bearing etc., and economic benefit is obvious.
