Description
Technical Field
The utility model relates to a sealing mechanism, concretely relates to rotary cultivator arbor bearing seal structure.
Background
The rotary cultivator comprises a cutter shaft, and the cutter shaft is arranged on the rack through a bearing seat. The rotary cultivator is a machine for farmland farming, and as mud and water are driven by the rotary cultivator during farming, a small amount of mud and water can rust the bearing after entering the housing of the bearing seat; meanwhile, the time of cultivation in one year is only a few days, namely the rotary cultivator is used for only a few days, and the rotary cultivator can be placed for no use in other time; when the bearing seat is not used after being placed for a long time, the bearing and the space between the bearing and the shaft are easy to rust due to the corrosion of the bearing in the bearing seat shell, so that the shaft cannot rotate; when the rotary cultivator is restarted, because rust between bearing and the axle dies, make the rotary cultivator arbor can not rotate, when the revolving force acted on the rotary cultivator arbor, lead to the rotary cultivator arbor to collapse easily. Therefore, the rotary cultivator generally seals the bearing seat in the production process so as to ensure that mud and water cannot enter the housing of the bearing seat. The existing sealing mode is generally as follows: the inner side of the bearing seat shell is in sliding seal with the shaft through a seal ring (felt, packing or rubber seal ring), and the outer side of the bearing seat shell is sealed through an end cover. After the rotary cultivator works for a long time, due to the long-time friction between the cutter shaft and the sealing ring, the cutter shaft easily abrades the sealing ring, so that the gap between the sealing ring and the cutter shaft is gradually enlarged, the sealing on the inner side of the bearing seat shell is failed, and mud and water easily enter the bearing seat shell from the inner side of the bearing seat shell. Therefore, the sealing structure needs to be improved to prevent the cutter shaft from being broken after the bearing and the cutter shaft are rusted.
Disclosure of Invention
The utility model aims to provide a: aiming at the defects of the prior art, the rotary tiller cutter shaft bearing sealing structure is not easy to rust and break.
The technical scheme of the utility model is that:
a rotary cultivator cutter shaft bearing sealing structure comprises a cutter shaft, a bearing seat shell, a bearing and an end cover, wherein the end of the cutter shaft is provided with the bearing seat shell; the method is characterized in that: a sealing shaft sleeve is sleeved on the cutter shaft at the inner side of the bearing, and the end surface of the sealing shaft sleeve is abutted and hermetically connected with the inner ring of the bearing; the end head of the cutter shaft outside the bearing is provided with a clamp spring through an installation groove, and the clamp spring is abutted against the inner ring of the bearing for sealing connection.
The end of the cutter shaft is in a step shape, and the diameter of the end of the cutter shaft decreases progressively from inside to outside.
The sealing shaft sleeve is also connected with the shoulder of the cutter shaft in a propping and sealing way.
The end surface of the bearing inner ring at one side of the sealing shaft sleeve is also abutted against and in sealing connection with the shoulder of the cutter shaft.
The sealing ring is connected with the sealing shaft sleeve in a sliding and sealing mode.
The beneficial effects of the utility model reside in that:
the rotary cultivator cutter shaft bearing sealing structure can seal the end surface of the bearing inner ring and further seal the bearing inner ring and the cutter shaft through the sealing shaft sleeve, so that mud and water are not easy to enter between the bearing inner ring and the cutter shaft, the bearing inner ring and the cutter shaft cannot be rusted after the sealing ring fails, and the cutter shaft and the bearing inner ring can also slide relatively after the bearing is rusted, so that the cutter shaft is not easy to be locked by the bearing, and the cutter shaft cannot be broken; because the circumferential acting force applied to the sealing shaft sleeve and the bearing inner ring is the rotating force of the cutter shaft to the sealing shaft sleeve and the bearing inner ring, the sealing shaft sleeve and the bearing inner ring cannot slide relatively, so that the sealing shaft sleeve and the bearing inner ring can be always kept sealed, the bearing inner ring and the cutter shaft are further prevented from being rusted, and the cutter shaft is prevented from being broken easily; the problem of current seal structure's sealing washer inefficacy back, the bearing leads to the arbor to collapse disconnected easily with the arbor lock.
