Description
Technical field
The present invention relates to a kind of delivering device, and in particular to a kind of ship unloaders large vehicle walking wheel with seal disc.
Background technology
Ship unloaders are the heads for being constructed to be lifted bulk granular material using continuous conveyor, or have voluntarily reclaiming capacity concurrently,
Or feeding, drawing-in device are equipped with, bulk granular material is continuously proposed into cabin, arm support or frame is then unloaded to and can be transported to
Bank master send in defeated place the special-purpose machinery that machine system is gone.Rate of discharging is greatly improved using ship unloaders, minimum dust is dirty
Dye can keep clean environment, high-efficiency environment friendly.Cart walking mechanism is the principle mechanical components of ship unloaders, and running wheel is capable
The key of mechanism is walked, if running wheel breaks down, causes cart not walk, so as to cause ship unloaders to perform off-bearger
Make.
At present, ship unloaders large vehicle walking wheel structure as shown in figure 3, including wheel hub, the horizontal rotary shaft in the wheel hub,
The end of the rotary shaft is provided with a gear drive disk, and the rotary shaft is the axle that diameter does not wait and small in ends broad in the middle, is located at
The bearing that is connected with it is set in the rotary shaft of wheel hub both sides, coordinates in two bearings and is provided with bearing cap, but bearing cap and
10mm gap between bearing be present, and this gap lower horizontal direction is bearing chamber, because ship unloaders are typically being mingled with powder
Worked under dirt environment, therefore dust can enter in bearing bore room from gap, bearing lubrication grease is hardened, and destroy bearing profit
It is sliding, and then cause bearing heavy wear, No. 1~2 bearing is typically monthly changed, environment is more severe, monthly changes 3~4 times,
Frequent, maintenance cost height is changed, and increases workload, has an effect on ship unloaders normal work.
The content of the invention
In view of the deficienciess of the prior art, the present invention provides a kind of ship unloaders large vehicle walking wheel with seal disc,
This running wheel is provided with a seal disc at the gap between bearing (ball) cover and bearing, realize the thorough seal of bearing, effectively resistance
Only dust enters bearing chamber, ensures bearing lubrication, prevents bearing wear, greatly reduce maintenance frequency, both reduce maintenance cost,
Also ensure ship unloaders normal work, and then improve rate of discharging.
In order to achieve the above object, the technical scheme that the present invention takes：
Ship unloaders large vehicle walking wheel with seal disc, including wheel hub, the horizontal rotary shaft in wheel hub, described turn
The end of moving axis is provided with a gear drive disk, the both ends of the rotary shaft and coordinates provided with a bearing positioned at the both sides of wheel hub,
The bearing cap coordinated with it is equipped with the bearing, a seal disc, the seal disc are provided between the bearing cap and bearing
Including the sealing inner ring being sheathed on bearing and the sealed outer ring being fixedly connected with bearing cap, and the sealed outer ring passes through screw
It is connected with the flange being fixedly mounted on bearing cap.
It is close in order to ensure to seal between seal disc and bearing as optimal technical scheme, further ensure that the complete of bearing
Face seals, while prevents seal disc from hindering the rotation of bearing, it is ensured that ship unloaders normal work, between the sealing inner ring and bearing
It is equipped with an elastic O-ring.
As optimal technical scheme, in order that seal disc has good sealing property, bearing and bearing are further ensured that
Sealed between lid, while make seal disc that there is good processability, it is ensured that seal disc simple installation, the seal disc are by gathering
Ptfe plastic material is made.
Compared with prior art, the device have the advantages that：
1st, a seal disc is provided with gap of this running wheel between bearing (ball) cover and bearing, realizes the comprehensive close of bearing
Envelope, effectively prevent dust from entering bearing chamber, ensure bearing lubrication, prevent bearing wear, greatly reduce maintenance frequency, both reduced
Maintenance cost, also ensure ship unloaders normal work, and then improve rate of discharging.
2nd, seal and an elastic O-ring is equipped between inner ring and bearing, ensure to seal closely between seal disc and bearing, enter
One step ensures the thorough seal of bearing, while prevents seal disc from hindering the rotation of bearing, it is ensured that ship unloaders normal work.
3rd, seal disc is made up of polytetrafluoroethylplastic plastic material, seal disc is had good sealing property, further
Ensure to seal between bearing and bearing cap, while make seal disc that there is good processability, it is ensured that seal disc simple installation.
Brief description of the drawings
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
