Description
[0001] The invention provides a closed traveling wheel for laterally-mounted machine, which
belongs to the technical field of transmission equipment.
[0002] There are two traditional idler wheel structures: the idler wheel is sleeved on the shaft
in hollow or, the rolling bearing is installed in the idler wheel, and the bearing is directly
sleeved on the shaft. The former has poor lubricity between the idler wheel and the pin, and
the idler wheel and pin are easy to wear; dust, mud, etc. are easy to enter between the rollers
and thereby cause the idler wheel to jam, and the axial movement is large; the unstable factors
are strong. For the latter, after the rolling bearing is installed, it is improved compared with
the traditional method; however, the inner ring of the bearing is sleeved on the shaft in hollow,
and the idler wheel bounces greatly; dust, mud, etc. are easy to enter between the bearings and
shafts and thereby cause the idler wheel to jam; the lubricity is poor, and the axial movement
is large; especially for traveling on complex roads for a long time, there are also major safety
hazards.
[0003] (1) Technical Problems Solved
[0004] In view of the shortcomings of the prior art, the invention provides a closed traveling
wheel for laterally-mounted machine, which solves the problems of poor lubricity between
the idler wheel and the pin, and that the idler wheel and pin are easy to wear; dust, mud, etc.
are easy to enter between the rollers and thereby cause the idler wheel to jam, and the axial
movement is large.
[0005] (2) Technical Solutions
[0006] In order to achieve the objectives, the invention is achieved through the following
technical solutions: a closed traveling wheel for laterally-mounted machine, comprising a
DESCRIPTION idler wheel body, wherein the inside of the idler wheel body is provided with a idler wheel inner hole; the inside of the idler wheel inner hole is provided with a closed bearing seat; one end of the closed bearing seat extends to the outside of the idler wheel inner hole and is rotatably clamped with the outer side wall of the idler wheel body, and the outer surface of the other end of the closed bearing seat is rotatably connected with a bearing; the outer surface of the bearing is fixedly connected to the inner side wall of the idler wheel body; the outer surface of the enclosed bearing seat is rotatably sleeved with a labyrinth steel disc all-metal sealing ring; the labyrinth steel disc all-metal sealing ring is arranged between the bearing and the idler wheel body; the outer surface of the labyrinth steel disc all-metal sealing ring is fixedly connected to the inner side wall of the idler wheel body; one end of the inner side wall of the idler wheel body away from the closed bearing seat isfixedly connected with a first sealing element; one side of the first sealing element away from the closed bearing seat is provided with a dustproof sealing cover; the dustproof sealing cover is clamped inside the idler wheel body; the inside of the closed bearing seat is provided with a bearing inner hole; the inner side wall of the closed bearing seat isfixedly connected with a second sealing element.
[0007] Preferably, the first sealing element and the second sealing element are both O-rings. The first sealing element has a sealing effect on the shaft and the bearing seat, and the second sealing element has a sealing effect on the idler wheel. The two are combined with the closed bearing and the labyrinth steel disc all-metal sealing ring to form a combination of multi-layer combined sealing methods, so that the pre-filled grease inside the idler wheel does not overflow, which achieves the effect of realizing lubrication-free during the use and maintenance of the idler wheel.
[0008] Preferably, the inner hole of the bearing and the outer diameter of the closed bearing seat, and the outer diameter of the bearing and the idler wheel inner hole adopt an interference fit, which can make the bearing seat and the shaft remain stationary, eliminate the radial gap in the traditional installation method, and make the transmission of the idler wheel more stable.
[0009] Preferably, the interior of the idler wheel body is pre-filled with grease. Due to the multi-layer combined sealing structure, the lubricating grease in the idler wheel will not be
DESCRIPTION lost and the bearings will be fully lubricated, which greatly improves the life of the idler
wheel and reduces maintenance costs.
[0010] Preferably, the outer surface of the closed bearing seat and the inner side wall of the
idler wheel body are both fixedly connected with a bearing limiting ring; the two bearing
limiting rings are both arranged on the same side of the bearing, which has a limiting effect on
the position of the bearing, and improves the stability of the device body during the traveling
process.
[0011] Working principle: when in use, the device is different from traditional equipment in
that a bearing seat structure is introduced and the bearing seat is made into a closed type to
prevent dust and granular materials from entering the idler wheel. At the same time, the inner
hole of the bearing and the outer diameter of the closed bearing seat, and the outer diameter of
the bearing and the idler wheel inner hole adopt an interference fit, which can make the
bearing seat and the shaft remain stationary, eliminate the radial gap in the traditional
installation method, and make the transmission of the idler wheel more stable. In addition, the
high-end sealing element of the labyrinth steel disc all-metal sealing ring can withstand axial
pressure, and at the same time can seal the grease lubricated bearing exposed to the extreme
pollution environment, which avoids the axial movement of the idler wheel. At the same time,
the interior of the idler wheel is pre-filled with grease. Due to the multi-layer combined
sealing structure, the lubricating grease in the idler wheel will not be lost and the bearings will
be fully lubricated, which achieves the effect that the idler wheel can be lubricated-free during
the use and maintenance process; the life of the idler wheel is greatly improved, and
maintenance costs are reduced.
[0012] (3) Advantageous Effects
[0013] The invention provides a closed traveling wheel for laterally-mounted machine, which
has the following advantageous effects:
[0014] 1. The high-end sealing element of the labyrinth steel disc all-metal sealing ring can
withstand axial pressure, and at the same time can seal the grease lubricated bearing exposed
to the extreme pollution environment, which avoids the axial movement of the idler wheel.
[0015] 2. In the closed traveling wheel for laterally-mounted machine, a bearing seat structure
is introduced and the bearing seat is made into a closed type to prevent dust and granular
DESCRIPTION materials from entering the idler wheel.
[0016] 3. In the closed traveling wheel for laterally-mounted machine, the inner hole of the bearing and the outer diameter of the closed bearing seat, and the outer diameter of the bearing and the idler wheel inner hole adopt an interference fit, which can make the bearing seat and the shaft remain stationary, eliminate the radial gap in the traditional installation method, and make the transmission of the idler wheel more stable.
[0017] 4. In the closed traveling wheel for laterally-mounted machine, the interior of the idler wheel is pre-filled with grease. Due to the multi-layer combined sealing structure, the lubricating grease in the idler wheel will not be lost and the bearings will be fully lubricated, which achieves the effect that the idler wheel can be lubricated-free during the use and maintenance process; the life of the idler wheel is greatly improved, and maintenance costs are reduced.
