Description

Detachable roller bearing seat mechanism Technical Field The utility model relates to the technical field of roller bearing seats, in particular to a detachable roller bearing seat mechanism. Background The roller bearing seat is located the roller both ends of drive harrow suppression assembly, plays fixed connection roller to assembly and makes the roller can pivoted effect. The existing standard component bearing seat is used as a bearing seat of a pressing roller, when the existing standard component bearing seat is used, if a bearing is worn out, the bearing is required to be replaced after being disassembled integrally, the time and effort are wasted when the bearing is damaged in advance, if the bearing is damaged during field operation, the replacement is time and effort consuming (the weight of the pressing roller is heavier), the operation efficiency is affected, the existing standard component bearing seat cannot be completely suitable for the field extreme environment and the severe service condition of a driving rake due to the general design limitation, the durability of a sealing element is poor, pollutants (such as gravel and dust) are easy to invade the inside of the bearing to accelerate the abrasion of the bearing, the service life of the bearing is reduced, and a part of the bearing seat cannot bear larger axial load. Disclosure of utility model The utility model aims to provide a durable detachable bearing seat mechanism which can predict whether bearing tightness is good in advance under the severe working condition of field operation of a driving harrow so as to solve the problems that the durability of a sealing element is poor and the bearing damage cannot be known in advance in the existing standard component bearing seat. The detachable pressing roller bearing seat mechanism comprises a bearing seat, a bearing seat welding piece, a clamp spring a, a round nut, a gasket, a backstop gasket, an oil seal a, a clamp spring b and an oil cup, wherein the bearing is rotationally connected inside the bearing seat welding piece, the bearing is sleeved on the bearing seat and is in interference fit with the bearing seat, the clamp spring a and the clamp spring b are arranged inside the bearing seat welding piece, the bearing seat is provided with a first step, the bearing is limited between the first step and the clamp spring a, the gasket is sleeved on the bearing seat positioned on the inner ring of the clamp spring a, the backstop gasket is tightly sleeved on the bearing seat, the round nut is sleeved at the end part of the bearing seat and is connected with the backstop gasket, the bearing seat welding piece is internally provided with a step, the oil seal a is arranged between the bearing seat and the bearing seat welding piece and is axially limited by the step and the clamp spring b, and the oil cup is fixed on the bearing seat welding piece. Preferably, the bearing housing has a second step. Preferably, the bearing seat further comprises an oil seal b, wherein the oil seal b is arranged between the bearing seat and the bearing seat welding piece adjacent to the oil seal a, and is limited by the second step of the bearing seat and the clamp spring b in the axial direction. Preferably, the bearing seat welding piece further comprises a sealing ring, the side end face of the bearing seat welding piece is provided with a groove, and the sealing ring is arranged in the groove. Preferably, the bearing seat welding device further comprises a round head cross bolt which is screwed on the bearing seat welding piece. Compared with the prior art, the bearing seat has the advantages that compared with the traditional standard component bearing seat, the bearing seat is more durable, the replacement frequency of a user can be reduced, the operation efficiency in an operation season is improved, the round nut and the aligning roller bearing are used, the detachable bearing seat can bear load in the vertical direction of the pressing roller and can bear larger axial load (when the user actually uses the bearing seat, the machine can not be lifted to turn around according to the use requirement and can directly drag the machine to turn around, the harrow pressing roller can be driven to form larger axial load on the bearing seat, meanwhile, the bearing seat can also predict the damage condition of a sealing element (oil seal) in advance through the resistance when butter is applied, so that the user can replace the sealing element in time in idle time, and the situation that the operation efficiency is affected due to the damage of a driving harrow pressing assembly when the user works in the field is avoided.
