Detailed Description
The embodiments of the invention are given below with reference to the accompanying drawings:
as shown in the figure: this embodiment is mainly by single-stage thrust tapered roller bearing, shaft collar (010), outer spacer ring (030), interior spacer ring (050), step shaft (060), seat ring constitution (020), positioning screw (070), single-stage thrust tapered roller bearing is a plurality of, it is through setting up inner spacer ring (050) between every single-stage thrust tapered roller bearing, outer spacer ring (030), seat ring (020) is with this a plurality of single-stage thrust cylindrical roller bearing series connection on the step shaft, with positioning screw (070) with locating hole (021) and the locating hole (062) of step shaft on last single-stage tapered roller bearing seat ring location, form that detachable takes shaft type tandem thrust tapered roller bearing whole (as shown in fig. 1). A race (020) is arranged in the middle of the inner spacer (050), the race (020) is fixedly connected with the inner spacer (050), a shaft ring (010) is arranged on the upper portion of the race (020), and a plurality of conical rollers (040) are arranged on the periphery between the shaft ring (010) and the race (020); the outer spacer ring (030) is arranged at the lower part of the inner spacer ring (050) and is fixedly connected with the inner spacer ring. The end of the stepped shaft forming a single thrust roller bearing structure is provided with a keyway (061) which can be directly butted against a screw shaft of an extruder to bear a strong thrust load. The end part of the stepped shaft close to the stepped shaft is provided with a step which is convenient for positioning the first single-stage tapered roller bearing ring. The bottom of the stepped shaft is provided with a positioning hole (061) which can be positioned with a positioning hole (021) of the last tapered roller bearing race, so that the shaft and the bearing are not easy to separate (as shown in fig. 4).
The shaft has two structures, one is a shaft without a lubricating oil hole (as shown in figure 1), when the shaft is used, the bearing assembly is soaked in thin oil, and circulating oil flows through gaps among parts of the bearing to fully lubricate the roller, the shaft and a race; another type is a shaft (as shown in fig. 2) having oil holes (063) and oil outlet (064) through which oil flows into the bearing to lubricate the components of the bearing when in use.
The bearing has two structures, a single-stage tapered thrust bearing without a lubricating oil hole (as shown in figure 1), a serial bearing is integrally immersed in thin oil when in use, circulating oil flows through gaps among parts of the bearing to be fully lubricated, and the other bearing is a bearing with an oil injection hole (031) and an oil outlet hole (032) on the outer ring of the single-stage tapered roller bearing (as shown in figure 3), and oil can be injected into the oil hole when in use, so that the parts of the bearing are lubricated.
