Abstract
The utility model relates to a biting roll bearing of a sintering machine, comprising an outer ring, roller pins, an inner ring and two check rings. The inner ring is installed on a biting roll shaft and is in interference fit with the biting roll shaft. An annular trough is arranged at the middle part inside the inner ring and is communicated with four radial oil filler holes. The two check rings are respectively installed at two sides of the inner ring and are directly contacted with the biting roll shaft, and the two sides of the radial oil filler holes outside the inner ring are filled with two rows of roller pins. The outer ring covers the two rows of roller pins and the two check rings, the two ends of the outer ring are in interference fit with the two check rings, and the middle of the outer ring is contacted with the roller pins. The parts on the two check rings, which are in interference fit with the outer ring, are respectively provided with a pair of sealing spring snap rings. The bearing has large carrying capacity, impact resistance, good sealing, flexible rotation, no easy abrasion and convenient maintenance.
Description
Technical field
The utility model relates to a kind of sintering pallet and nibbles roller bearing, is that a kind of sintering pallet is nibbled the nonstandard double-row full-complement needle bearing of using on the roller specifically.
Background technique
Sintering pallet is the vitals of steel-making SINTERING PRODUCTION wire system, carrying is big, and operating mode is abominable and complicated, works long hours in alternating thermal stress and dust pollution serious environmental, but also will bear in the impact at bend place end to end, this has just caused the regular of chassis to fall to take turns and axial float.Nibble roller bearing on the shaft part between bogie wheels and the car body, main effect is in the bend movement process that turns under rising of chassis great wheel and tail wheel, drives the smooth upset of chassis by the engagement driving with star wheel toothed plate.Bearing is as the critical piece of nibbling roller transferring power and bearing load when bend, and its performance affects the operational situation of chassis to a great extent, and then affects the life-span of SINTERING PRODUCTION wire system really.Existing technical pattern is installation sleeve cartridge type sliding bearing or the oil-containing solids lubricating bearings on the roll shaft nibbled between chassis and wheel.The problem that this structure exists is: the sliding bearing sealability is bad, under the bad working environments, oiling agent is easy to lose efficacy, and very easily produces dry friction, causes axle sleeve, axle journal heavy wear and scraps, or axle, axle sleeve, nibble between roller and kill, not working easily causes the chassis arch camber and sticks up tail that more serious consequence is that chassis is gnawed mutually, air leak rate of air curtain increases, even chassis sideslip arterial highway; In addition, the rigidity slideway sealing of chassis operation is very high to the requirement of oiling agent, needs regular it is overhauled, and the dismounting difficulty of sliding bearing, frequent shutdown maintenance causes the installation and maintenance expense of whole system to increase, and has influenced the overall operation of system, has reduced productivity; And existing structure is very big to the oiling agent consumption.
The model utility content
The purpose of this utility model is the deficiency at prior art, provide that a kind of bearing capacity is big, shock-resistant, good seal, rotation flexibly, sintering pallet easy to wear and not easy to maintenance nibbles roller bearing.
In order to achieve the above object, the utility model adopts following technical proposals:
A kind of sintering pallet is nibbled roller bearing, be that a kind of sintering pallet is nibbled the nonstandard double-row full-complement needle bearing of using on the roller specifically, comprise inner ring, back-up ring, needle roller and outer ring, it is characterized in that: described inner ring is installed in to be nibbled on the roll shaft, with nibble the roll shaft interference fit, the intermediate portion of inner ring inside has circumferential groove to be communicated with four radially oil holes; Respectively there is a described back-up ring on the inner ring both sides, and nibble roll shaft and directly contact; Inner ring completely is equipped with the described needle roller of two row outward; Described outer ring covers described two row needle rollers and two back-up rings, its two ends and two back-up ring Spielpassung, and the centre contacts with needle roller, and on described two back-up rings, the contacting point of outer ring and both sides back-up ring respectively is equipped with a pair of Packing spring snap ring.
The utility model has following conspicuous outstanding feature and advantage compared with prior art: the utility model is nibbled roller bearing and directly is enclosed within and nibbles on the roll shaft, installs, convenient disassembly; Completely adorn the biserial needle roller in the bearing, make original sliding friction become rolling friction, bearing capacity is big, rotates flexibly; Be communicated with by circumferential groove on the inner ring four radially oil hole make things convenient for the interpolation and the maintenance of oiling agent; The use of paired Packing spring snap ring makes that dust is difficult for invading, and lubricating grease is difficult for inefficacy and leaks, and needle roller and lasso are not easy to wear, can realize the long-time maintenance use of not having.Nibble roller shell cartridge type sliding bearing and compare with existing, the existing roller shell cartridge type sliding bearing of nibbling needed overhaul to change in 3～6 months, and the utility model 3～5 years just overhaul is changed, and has improved 10 times working life, has reduced maintenance cost, has improved productivity.
Description of drawings
Fig. 1 is a sectional view of the present utility model.
Embodiment
Introduce a preferred embodiment of the present utility model below in conjunction with accompanying drawing:
With reference to Fig. 1, this sintering pallet is nibbled roller bearing and is comprised outer ring 1, needle roller 2, inner ring 3 and back-up ring 4.Inner ring 3 is installed in to be nibbled on the roll shaft, and nibbles the roll shaft interference fit, and the intermediate portion of inner ring 3 inside has a circumferential groove 7 to be communicated with four radially oil holes 6, convenient interpolation and maintenance to oiling agent.Two back-up rings 4 are installed in the both sides of inner ring 3 respectively, directly contact with nibbling roll shaft, needle roller 2 are played the effect of axially locating.Two row needle rollers 2 completely are equipped with in inner ring 3 outer radial oil holes 6 both sides, have improved the bearing capacity of bearing.Outer ring 1 covers two row needle rollers 2 and two back-up rings 4, its two ends and two back-up rings, 4 Spielpassung, and the centre contacts with needle roller 2.On two back-up rings 4, with 1 cooperation place, outer ring a pair of Packing spring snap ring 5 is installed respectively, good airproof performance, oiling agent is difficult for to external leakage, and external dust is difficult for entering, and can make bearing realize long-time the use.
