Description
Technical field
The present invention relates to a kind of paddy field machine chassis walking wheel rotary sealing appts, particularly relate to the simple but paddy field machine chassis walking wheel automatic pressure-maintaining rotary sealing appts of good sealing effect of a kind of structure.
Background technology
The walking wheel on paddy field machine chassis, because it works for a long time in muddy water, often causes wear-out of a bearing, corrosion because water, silt particle etc. enter bearing, makes bearing early failure, causes road wheel to damage.Current mud water sealing structure has: contact oil seal seals, and structure is simple but sealing effectiveness is poor, and the wearing and tearing caused because of silt particle cause oil sealing and axle, bearing damage; Contactless labyrinth+oil sealing sealing, structure is comparatively complicated and silt particle still can invade oil sealing causes early failure; Combined grease seal (namely oil sealing self turns kinematic pair once) cost is higher and the rear silt particle of wearing and tearing still can invade bearing; Other sealing is not applied because of structure and cost reason in paddy field machine.
Summary of the invention
The object of the invention is for background technology Problems existing, design that a kind of structure is simple, the paddy field machine chassis walking wheel automatic pressure-maintaining rotary sealing appts of good sealing effect.
Technical scheme of the present invention is: a kind of paddy field machine chassis walking wheel automatic pressure-maintaining rotary sealing appts, comprise axle, axle sleeve, inside cap, inside cap packing ring, spring washer, tightening seal washer, oil sealing, semiclosed bearing, roller bearing end cap, road wheel, described axle is arranged in the frame axle sleeve of paddy field machine, road wheel is arranged on axle by bearing, it is characterized in that: be provided with spring washer and tightening seal washer between inside cap and axle; Described inside cap keeps 0.1-2Mpa precompressed compression by the binding face of pre-pressing to tightening seal washer and axle of spring washer, and the sealing surface of tightening seal washer is fitted tightly when there is relative rotation with the sealing surface of axle.
The precompressed compression that inside cap of the present invention is kept by the pre-pressing of the spring washer binding face to tightening seal washer and axle is realized by the elastic force of the inside cap gasket thickness between adjustment inside cap and road wheel and/or spring washer itself.
The precompressed compression of the binding face of tightening seal washer of the present invention and axle is 0.1-0.5Mpa or 0.4-1Mpa or 0.8-1.5Mpa or 1.0-2Mpa or 0.5-2Mpa.
The binding face of tightening seal washer of the present invention and axle is plane or circular conical surface.
Spring washer of the present invention is made by having elastomeric compactness material, is specially steel or rubber or its complex.
The material of tightening seal washer of the present invention is steel or cast iron or copper alloy or partial metallurgy or plastics or stupalith.
The words of oil sealing of the present invention are arranged towards semiclosed bearing.
Inside cap of the present invention is provided with oil filling hole, fills with lubricating oil or lubricating grease between its inside cap and oil sealing.
Automatic pressure-maintaining slewing arrangement of the present invention is applied on 1G series crawler belt rotovator.
Automatic pressure-maintaining slewing arrangement of the present invention is applied on 4LZ series caterpillar band harvester.
Technical essential of the present invention is: combined by inside cap, spring washer, tightening seal washer, oil sealing, axle, forms a kind of automatic pressure-maintaining rotary sealing appts.During assembling, inside cap keeps pressure by the binding face of pre-pressing to tightening seal washer and axle of spring washer, the sealing surface of tightening seal washer is fitted tightly when there is relative rotation with the sealing surface of axle, thus the impurity such as silt particle, water is blocked in outside, the words of oil sealing are inside, the leakage of block axis bearing lubrication oil; Combine and both can effectively prevent the impurity such as silt particle, water from entering oil sealing, effectively can prevent again the oil leak in bearing.Ensure that the works fine environment that bearing lubrication is clean, improve the service life of bearing, again because the lubricating oil between inside cap and oil sealing lubricates oil sealing, also improve functional reliability and the service life of oil sealing.

Detailed description of the invention
Embodiment 1
As shown in Figure 1 and Figure 2, the present invention forms primarily of axle 1, axle sleeve 2, inside cap 3, spring washer 4, tightening seal washer 5, oil sealing 6, semitight bearing 7, road wheel 8, roller bearing end cap 10, inside cap packing ring 11, and inside cap is provided with oil filling hole 9.Spring washer 4 of the present invention and tightening seal washer 5 are arranged on the axle between inside cap 3 and axle 1.
The present invention is combined by inside cap, spring washer, tightening seal washer, oil sealing, axle, forms a kind of 1G series crawler-type rotary cultivator automatic pressure-maintaining rotary sealing appts.The pre-pressing force of adjustable elastic packing ring to tightening seal washer is carried out by the elastic force of the inside cap gasket thickness between adjustment inside cap and road wheel and spring washer during assembling, the precompressed compression of the binding face of tightening seal washer and axle is made to be between 0.1-2Mpa, tightening seal washer is fitted tightly thus outside being blocked in by the impurity such as silt particle, water when there is relative rotation with the binding face of axle, the words of oil sealing are inside, the leakage of block axis bearing lubrication oil; Combine and both can effectively prevent the impurity such as silt particle, water from entering oil sealing, effectively can prevent again the oil leak in bearing.Ensure that the works fine environment that bearing lubrication is clean, improving the service life of bearing, again because the filler port on inside cap can lubricate oil sealing by charging-up lubricant oil, also improve functional reliability and the service life of oil sealing.
