Abstract
The utility model relates to a track roller unit for tracked self-propelled harvesters. The track roller unit mainly comprises a track roller shaft, a labyrinth shaft sleeve, a felt ring, a bearing cap, an oil seal A, an oil seal B, a track roller, a semi-closed bearing and a bearing end cap. The track roller shaft is mounted on the labyrinth shaft sleeve of the chassis of a tracked self-propelled harvester, the track roller is mounted on the track roller shaft through the semi-closed bearing, and the semi-closed bearing is sealed by the sealing combination of the labyrinth seal, the felt ring seal and the two oil seals. The track roller unit has the outstanding effects that since the bearing of the track roller of the tracked self-propelled harvester is under the quadruple protection of the labyrinth seal, the felt ring seal and the two oil seals, a good working environment of clean lubrication still can be guaranteed even if the tracked self-propelled harvester often operates in the muddy paddy field, so that the service life of the bearing can be greatly prolonged, and the service reliability of the tracked self-propelled harvester can be greatly enhanced.
Description
Technical field
The utility model relates to a kind of labyrinth, felt collar and oil sealing combination sealing thrust wheel device of caterpillar band self-propelled reaper.
Background technology
The caterpillar wheel on facility chassis such as caterpillar band self-propelled reaper is worked muddy water Tanaka for a long time because of it, tends to cause wear-out of a bearing, axle wearing and tearing because water, mud etc. enters, and makes its early failure, causes the oil sealing of caterpillar wheel and bearing to damage easily.
Summary of the invention
The purpose of this utility model is the problem that exists at background technology, designs a kind of band labyrinth, felt collar and oil sealing combination sealing thrust wheel device simple in structure, convenient, suitable.
The technical solution of the utility model is: a kind of thrust wheel device of caterpillar band self-propelled reaper mainly comprises supporting wheel shaft, labyrinth axle sleeve, felt collar, bearing cap shim, oil sealing A, oil sealing B, caterpillar wheel, semiclosed bearing and roller bearing end cap; It is characterized in that: described supporting wheel shaft is installed on the frame labyrinth axle sleeve of caterpillar band self-propelled reaper; Described caterpillar wheel is installed on the supporting wheel shaft by semiclosed bearing; Described bearing cap shim is installed in the left end of caterpillar wheel by screw; Described felt collar is arranged in the felt collar groove of labyrinth axle sleeve, and contacts with the protruding circle of bearing cap shim left end; Described oil sealing A and oil sealing B are installed in respectively on the labyrinth axle sleeve and supporting wheel shaft between semitight bearing and the bearing cap shim; The words of oil sealing A are outside, and the words of oil sealing B are inside; Described roller bearing end cap is installed in the right-hand member of caterpillar wheel by screw.
The utility model adopts labyrinth, felt collar and two oil sealings combinations, and labyrinth, felt collar are filtered silt and be blocked in outside the oil sealing, has only the water can be by labyrinth and felt collar; The words of oil sealing A are outside, the entering of block water; The words of oil sealing B are inside, stop the leakage of lubricating oil; Two oil sealings fit together both can prevent effectively that sealing enters between the interior outer oil seal, can effectively prevent the oil leak in the bearing again.Works fine environment having guaranteed the bearing lubrication cleaning improves the service life of bearing simultaneously, again because felt collar to the filtration of silt, has guaranteed the working environment that oil sealing A and B clean, functional reliability and the service life of also having improved oil sealing simultaneously.
Description of drawings
Fig. 1 is the utility model inner structure scheme drawing.
Among the figure: 1, supporting wheel shaft; 2, labyrinth axle sleeve; 3, felt collar; 4, bearing cap shim; 5, oil sealing A; 6, oil sealing B; 7, caterpillar wheel; 8, semiclosed bearing; 9, roller bearing end cap.
The specific embodiment
As shown in Figure 1, the utility model is made up of supporting wheel shaft 1, labyrinth axle sleeve 2, felt collar 3, bearing cap shim 4, oil sealing A5, oil sealing B6, caterpillar wheel 7, semiclosed bearing 8 and roller bearing end cap 9; It is characterized in that: supporting wheel shaft 1 is installed on the frame labyrinth axle sleeve 2 of caterpillar band self-propelled reaper; Caterpillar wheel 7 is installed on the supporting wheel shaft 1 by semiclosed bearing 8; Bearing cap shim 4 is installed in the left end of caterpillar wheel 7 by screw; Felt collar 3 is arranged in the felt collar groove of labyrinth axle sleeve 2, and contacts with the protruding circle of bearing cap shim 4 left ends; Oil sealing A5 and oil sealing B6 are installed in respectively on the labyrinth axle sleeve 2 and supporting wheel shaft 1 between semitight bearing 8 and the bearing cap shim 4; The words of oil sealing A5 are outside, and the words of oil sealing B6 are inside; Roller bearing end cap 9 is installed in the right-hand member of caterpillar wheel 7 by screw.
The utility model thrust wheel device is by labyrinth, felt collar and two oil sealings combinations, labyrinth, felt collar with silt filter be blocked in outside, have only the water can be by labyrinth and felt collar; The words of oil sealing A are outside, the entering of block water; The words of oil sealing B are inside, stop the leakage of lubricating oil; Two oil sealings fit together both can prevent effectively that sealing enters between the interior outer oil seal, can effectively prevent the oil leak in the bearing again.Works fine environment having guaranteed the bearing lubrication cleaning improves the service life of bearing simultaneously, again because felt collar to the filtration of silt, has guaranteed the working environment that oil sealing A and B clean, functional reliability and the service life of also having improved oil sealing simultaneously.
Embodiment of the present utility model is the description to preferred embodiment of the present utility model; be not that scope of the present utility model and design are limited, the various modification under the prerequisite that does not break away from the utility model design philosophy and improvement all should fall into protection domain of the present utility model.
