Abstract
The invention discloses a milling machine. The milling machine comprises a bearing block, an end cover, a rotating shaft, a roller, a bearing and an oil seal, wherein the end cover is arranged at the bottom of the bearing block; the rotating shaft is arranged in the bearing block; the rotating shaft is connected with the roller in an electric soldering way; the bearing is arranged between the bearing block and the rotating shaft; and oil seal is arranged between the rotating shaft and the bearing block and is used for sealing; the oil seal is adjacent to the bearing; the contact surface between the oil seal and the rotating shaft is provided with a connection sleeve; the connection sleeve is embedded in the rotating shaft; a gland is arranged on the outer end face of the oil seal; a press plate is arranged on the end part of the rotating shaft; and a gap is reserved between the press plate and the end cover. The milling machine can well guarantee the free gap of the bearing to reduce the assembly difficulty; and the structure is applicable to a shaft with large radial load, can endure small bidirectional axial load, is in accordance with the working mode of a milling drum, and protects the bearing of the milling drum from being easily broken.
Description
Technical field
The present invention relates to a kind of milling machine, particularly be the non-damageable milling machine of a kind of milling and planing drum bearing.
Background technology
Pavement milling machine is one of main machine of asphalt pavement conserving construction machinery; Be mainly used in asphalt concrete surface layers such as highway, urban road and remove diseases such as gathering around bag, oil wave, reticulate pattern, rut, be widely used in the maintenance project of cities and towns town road and speedway.Milling and planing drum is the critical component in the milling machine, in the process of using, directly affects the operating efficiency of milling machine.The braced structures of present employed its milling and planing drum of milling machine is the two ends fixed support structure, and the service condition of this supporting form does not conform to the work characteristics of milling machine, in the process of work; The left and right sides span of milling and planing drum is bigger, and milling machine can produce great amount of heat when work; Have certain thermal deformation, in assembling process, because of the weldering between distortion, mismachining tolerance and adjust improper; Make the play of bearing can't reach the requirement of bearing, cause the milling and planing drum damage of bearings of milling machine.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed the non-damageable milling machine of a kind of milling and planing drum bearing.
Technical solution of the present invention is achieved in that a kind of milling machine, comprises bearing support, end cap, rotating shaft, cylinder, bearing and oil sealing, and the bottom of said bearing support is provided with end cap; Be provided with rotating shaft in the said bearing support; Said rotating shaft electric welding is connected with cylinder, is provided with bearing between said bearing support and the rotating shaft, uses oil sealing sealing between said rotating shaft and the bearing support; Said oil sealing and bearing are adjacent, and the contact surface place between said oil sealing and rotating shaft is provided with adapter sleeve; Said adapter sleeve is embedded in the rotating shaft; The outer face of said oil sealing is provided with gland; The end of said rotating shaft is provided with pressing plate; Leave the gap between said pressing plate and the end cap.
Preferably, said bearing support peripheral hardware dust ring; The inner face of said dust ring is connected with the rotating shaft contact.
Preferably, said bearing support is connected with end cap through securing member; Be connected with securing member between said gland and the bearing support; Be fixedly connected through securing member between said pressing plate and the rotating shaft.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Milling machine of the present invention, because the contact surface place between oil sealing and rotating shaft is provided with adapter sleeve, adapter sleeve is embedded in the rotating shaft; The outer face of oil sealing is provided with gland, and the end of rotating shaft is provided with pressing plate, leaves the gap between pressing plate and the end cap; So just can guarantee the play of bearing well, reduced assembly difficulty, and this structure be applicable to the axle that radial load is bigger; Can bear less bi-directional axial load, consistent with the working method of milling and planing drum, the milling and planing drum bearing that makes is not fragile; And bearing support peripheral hardware dust ring, the inner face of dust ring is connected with the rotating shaft contact, can avoid foreign material such as dust and water to get into the corrosion that in the bearing support bearing is caused.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing 1 is the structural representation of milling machine of the present invention;
Wherein: 1, bearing support; 2, end cap; 3, rotating shaft; 4, cylinder; 5, bearing; 6, oil sealing; 7, adapter sleeve; 8, gland; 9, pressing plate; 10, dust ring; 11, securing member.
