Abstract
The utility model relates to a felt ring and oil seal combined sealing thrust wheel device of a crawler self-propelled rotary tiller. The felt ring and oil seal combined sealing thrust wheel device mainly comprises a rack bushing, a thrust wheel shaft, a felt ring, a bearing cover with a felt ring groove, an oil seal A, an oil seal B, a semi-enclosed bearing, a thrust wheel and a bearing end cap, wherein the thrust wheel shaft is mounted on the rack bushing of the crawler self-propelled rotary tiller, the thrust wheel is mounted on the thrust wheel shaft through the semi-enclosed bearing, and the semi-enclosed bearing is subjected to combined sealing by the felt ring and the two oil seals. The felt ring and oil seal combined sealing thrust wheel device has the outstanding effects that the thrust wheel bearing of the crawler self-propelled rotary tiller is under the triple protection of the felt ring and the two oil seals, so that even if the crawler self-propelled rotary tiller works in muddy fields frequently, a good lubricated and clean work environment can be guaranteed, the service life of the bearing is greatly prolonged, thus, the use reliability of the crawler self-propelled rotary tiller is greatly improved.
Description
Technical field
The utility model relates to a kind of felt collar and oil sealing combination sealing thrust wheel device of caterpillar band self-propelled rotovator.
Background technology
The caterpillar wheel on facility chassis such as caterpillar band self-propelled rotovator 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 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 felt collar of caterpillar band self-propelled rotovator and oil sealing combination sealing thrust wheel device, mainly formed by frame axle sleeve, supporting wheel shaft, felt collar, band felt collar groove bearing lid, oil sealing A, oil sealing B, semiclosed bearing, caterpillar wheel, roller bearing end cap; It is characterized in that: described supporting wheel shaft is installed on the frame axle sleeve; Described caterpillar wheel is installed on the supporting wheel shaft by semiclosed bearing; Described band felt collar groove bearing lid is installed in the left end of caterpillar wheel by screw; Described felt collar is arranged in the felt collar groove of bearing cap shim, and its inner ring closely contacts with the frame axle sleeve; Described oil sealing A and oil sealing B are installed on the supporting wheel shaft between semiclosed bearing and the band felt collar groove bearing lid; 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 is by felt collar and two oil sealing combinations, and felt collar filters silt and is blocked in the outside, has only water can pass through 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, frame axle sleeve; 2, supporting wheel shaft; 3, felt collar; 4, band felt collar groove bearing lid; 5, oil sealing A; 6, oil sealing B; 7, semiclosed bearing; 8, caterpillar wheel; 9, roller bearing end cap.
The specific embodiment
As shown in Figure 1, the utility model is made up of frame axle sleeve 1, supporting wheel shaft 2, felt collar 3, band felt collar groove bearing lid 4, oil sealing A5, oil sealing B6, semiclosed bearing 7, caterpillar wheel 8, roller bearing end cap 9; It is characterized in that: described supporting wheel shaft 2 is installed on the frame axle sleeve 1; Described caterpillar wheel 8 is installed on the supporting wheel shaft 2 by semiclosed bearing 7; Described band felt collar groove bearing lid 4 is installed in the left end of caterpillar wheel 8 by screw; Described felt collar 3 is arranged in the felt collar groove of bearing cap shim, and its inner ring closely contacts with the frame axle sleeve; Described oil sealing A5 and oil sealing B6 are installed on the supporting wheel shaft 2 between semiclosed bearing 7 and the band felt collar groove bearing lid 4; The words of oil sealing A5 are outside, and the words of oil sealing B6 are inside; Described roller bearing end cap 9 is installed in the right-hand member of caterpillar wheel by screw.
The utility model thrust wheel device is by felt collar and two oil sealing combinations, and felt collar filters silt and is blocked in the outside, has only water can pass through 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 described in the 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.
